In the present embodiment, a dental laser device 150, which will be described in detail later, is accommodated.

FIG. 2 is a block diagram showing an apparatus configuration in a dental treatment unit according to an embodiment of the present invention, and FIG. 3 shows an internal structure of a dental laser device in a dental treatment unit according to an embodiment of the present invention FIG.
The air turbine 131 is detachable with respect to the turbine hose 122 so that an optimum handpiece can be appropriately selected according to the state of the affected area. The air turbine 131 is rotated by the air turbine main body 131a rotated by the air turbine driving air (compressed air) DA supplied from the turbine hose 122, and the rotational power V of the air turbine main body 131a attached to the air turbine main body 131a. And a rotating cutting bar 131b. By supplying the air turbine driving air DA to the air turbine main body 131a, the cutting bar 131b is rotated together with the air turbine main body 131a to cut the affected area. The air turbine driving air DA supplied to the air turbine main body 131a returns to the turbine hose 122 again after passing through the air turbine main body 131a.
Furthermore, the air turbine 131 has a liquid jet port 131c and an air jet port 131d for injecting water W and air A for cooling the affected area while cutting the affected area.

A turbine hose 122 extending from the work table 120 supplies the air turbine 131 with various fluids. That is, the turbine hose 122 supplies the air turbine driving air DA, the water W, and the air A to the air turbine 131, and recovers the air turbine driving air DA that has passed through the air turbine main body 131a. In other words, the turbine hose 122 has an air turbine drive air supply passage 122a, a water supply passage 122b, an air supply passage 122c, and an air turbine drive air exhaust passage 122d.
Further, a light source (LED) 122e is attached to the tip of the turbine hose 122, and a light beam L is emitted in the long axis direction.

The foot controller 140 is electrically connected to the work table 120, and transmits a control signal S corresponding to the operation on the foot controller 140 to a control unit (not shown) of the dental treatment unit 100. The control unit of the dental treatment unit 100 having received the control signal S adjusts the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 when the air turbine 131 is pulled out of the instrument holder 121.
When the micro engine 132 or the ultrasonic scaler 133 is removed from the instrument holder 121, the control unit in the work table 120 that receives the control signal S adjusts the amount of current supplied to each.

The dental laser device 150 is detachable from the turbine hose 122 in the same manner as the air turbine 131. The dental laser device 150 generates a laser beam and irradiates the patient with a laser irradiation mechanism 151, and an air supply detection unit 152 that senses air for driving an air turbine supplied from the turbine hose 122 to the dental laser device 150. And.
In the present embodiment, a pressure-sensitive element is used as the air supply detection unit 152, and the pressure in the flow path is detected by the pressure-sensitive element. It may be arranged.
Further, the dental laser device 150 further has a liquid jet port 153 and an air jet port 154 for jetting water W and air A for cooling the affected area while cutting the affected area.

  The dental laser device 150 has a substantially cylindrical shape, and a substantially cylindrical recess 150 a is formed on one end side, and the tip of the turbine hose 122 is inserted into the recess 150 a. Thereby, the dental laser device 150 is connected and communicated with the turbine hose 122.

As described above, the dental laser device 150 includes the laser irradiation mechanism 151 that generates a laser beam and irradiates the patient. The laser irradiation mechanism 151 includes a laser diode 151a that generates a laser beam, a heat sink 151b that abuts on the laser diode 151a to release heat generation of the laser diode 151a, and a laser conductor that a laser beam generated from the laser diode 151a passes. It has an optical path 151c, and a chip 151d connected to the exit side of the laser light guide 151c for irradiating the affected part with a laser beam.
The laser irradiation mechanism 151 further includes a power supply 151e for supplying power to the laser diode 151a, and a controller 151f for controlling the amount of power supplied to the laser diode 151a. In the present embodiment, the power supply 151 e is a lithium ion battery.

  The dental laser device 150 has a light guide path 155 through which the light beam L emitted by the light source 122 e of the turbine hose 122 passes. One end of the light guide path 155 is formed in the recess 150 a, and the other end is formed with a guide light irradiation port 156. Thus, the light beam L emitted from the light source 122 e of the turbine hose 122 is irradiated from the guide light irradiation port 156 onto the affected area, and the area around the affected area can be brightly illuminated.

  Further, the dental laser device 150 has a flow path for air turbine driving air DA, a flow path of air A, water W supplied from the turbine hose 122 and a flow path for discharging the air turbine driving air DA to the turbine hose 122 Have. That is, the dental laser device 150 includes an air turbine drive air introduction passage 157a, an air turbine drive air discharge passage 157b, a water flow passage 157c, and an air flow passage 157d.

All one ends of these flow paths are formed in the recess 150a. The other end of the air turbine drive air introduction passage 157 a and the other end of the air turbine drive air discharge passage 157 b communicate with the air chamber 158. That is, the air turbine drive air introduction passage 157 a and the air turbine drive air discharge passage 157 b communicate with each other via the air chamber 158.
The aforementioned heat sink 151 b is in contact with the air chamber 158. Thus, the heat generated by the laser diode 151a is dissipated to the air chamber 158 via the heat sink 151b.
In addition, a liquid jet port 153 is formed at the end of the water flow path 157c. Similarly, an air jet port 154 is formed at the end of the air flow path 157d.

  The air turbine drive air introduction path 157a is bifurcated in the middle, and an air supply detection means 152 is attached to one end.

  The tip 151d, the liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are formed on the tip side of the dental laser device 150 (the side opposite to the side on which the recess 150a is formed). The liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are disposed in the vicinity of the tip 151d.

Further, the opening positions of the light guide path 155, the air turbine drive air introduction channel 157a, the air turbine drive air discharge channel 157b, the water channel 157c, and the air channel 157d formed in the recess 150a are When the dental laser device 150 and the turbine hose 122 are connected, the light source 122e, the air supply path 122a for driving the air turbine, the water supply path 122b, the air supply path 122c, and the air exhaust for driving the air turbine It is located opposite to the passage 122d. That is, the opening of the light guiding path 155 faces the light source 122e, the opening of the air turbine driving air introduction path 157a faces the opening of the air turbine driving air supply path 122a, and the opening of the air turbine driving air discharge path 157b. The opening of the water flow path 157c faces the opening of the water supply path 122b, and the opening of the air flow path 157d faces the opening of the air supply path 122c.
Although not illustrated, the turbine hose 122 is provided with a plurality of sealing mechanisms. Thus, when the turbine hose 122 and the dental laser device 150 are connected, the air turbine drive air supply passage 122a, the water supply passage 122b, the air supply passage 122c, and the air turbine drive air exhaust passage 122d. And each is independent. Therefore, for example, leakage of water in the water supply passage 122b to the air turbine driving air supply passage 122a or the like is suppressed.

Next, the usage method and operation of the dental laser device 150 will be described using FIGS. 2 and 3.
As described above, the dental laser device 150 is removable with respect to the turbine hose 122 to which the air turbine 131 is usually connected. When using the dental laser device 150, the turbine hose 122 is removed from the air turbine 131 and connected to the dental laser device 150. At this time, the tip of the turbine hose 122 is inserted into the recess 150 a of the dental laser device 150.

Then, if it is desired to irradiate the affected area with a laser beam, the dentist steps on the foot controller 140. Thus, the air turbine driving air DA is supplied from the turbine hose 122 to the dental laser device 150 through the air turbine driving air supply passage 122a. The air turbine driving air DA supplied to the dental laser device 150 flows into the air turbine driving air introduction path 157a. Then, a part of the air turbine driving air DA is supplied to the air supply detection means 152 and the rest is supplied to the air chamber 158 by a branch provided in the air turbine driving air introduction path 157 a. Since air pressure is applied to the air supply detection means 152 by supplying the air turbine driving air DA to the air supply detection means 152, the air supply detection means 152 applies the air pressure to the dental laser device 150. It detects that the air turbine drive air DA has been supplied.
When the air supply detection means 152 detects the air turbine driving air DA, a detection signal is transmitted to the controller 151f, and the controller 151f energizes the laser diode 151a. Thereby, a laser beam is irradiated from the laser diode 151a, passes through the laser light guide path 151c, and is irradiated from the chip 151d toward the affected part.
At this time, water W is supplied from the turbine hose 122 to the dental laser device 150, and the water W passes through the water flow path 157 c in the dental laser device 150 and is jetted from the liquid jet port 153. Further, air A is also supplied from the turbine hose 122 to the dental laser device 150, and the air A passes through the air flow path 157 d in the dental laser device 150 and is jetted from the air jet port 154.

  On the other hand, the air turbine driving air DA supplied to the air chamber 158 passes through the air turbine driving air discharge path 157 b and is discharged to the air turbine driving air exhaust path 122 d in the turbine hose 122. Here, since the heat sink 151b is in contact with the air chamber 158, the heat of the laser diode 151a is conducted to the air chamber 158, so that the air for driving the air turbine DA passes through the air chamber 158, so that the laser diode The heat generation 151a can be conducted to the air turbine driving air DA. That is, the air turbine driving air DA can cool the laser diode 151a.

The foot controller 140 can also output a control signal S according to the stepping amount of the dentist. That is, the foot controller 140 does not output the simple ON / OFF binary value, but can output a plurality of values. When such a foot controller 140 is used, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 is also not a constant value, and a plurality of instantaneous flow rates can be supplied. In the present embodiment, as the foot controller 140 is depressed, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 can be increased.
The dental laser device 150 can also detect various instantaneous flow rates (in the present embodiment, air pressure) in addition to detecting simple ON / OFF binary values by the air supply detection means 152. Therefore, not only the binary values corresponding to ON / OFF from the air supply detection unit 152 but also various values from the air supply detection unit 152 are input to the controller 151 f. The controller 151 f can change the voltage applied to the laser diode 151 a according to the input value from the air supply detection means 152. In the present embodiment, as the value input from the air supply detection means 152 becomes larger (that is, as the foot controller 140 is depressed), the voltage applied to the laser diode 151a becomes larger, and the output of the laser beam becomes larger.

  The dental treatment unit 100 and the dental laser device 150 configured and operating in this manner are lasers by the dental laser device 150 according to the presence or absence of the air turbine driving air DA which is compressed air supplied to the dental laser device 150. By switching the irradiation and non-irradiation of the beam, it is not necessary to provide a dedicated foot controller for operating the dental laser device 150, so the foot of the dentist can be cleaned and the working environment can be improved.

  Furthermore, the output of the laser beam emitted from the laser irradiation mechanism 151 of the dental laser device 150 is adjusted according to the instantaneous flow rate detected by the air supply detection means 152, so that the laser can be operated only by the operation to the foot controller 140. Since the power of the beam can be changed, the usability of the dental laser device 150 can be improved.

  Furthermore, since the air supply detection means 152 is a pressure-sensitive element, it has a simple structure as compared with the case where the air turbine driving air DA is detected based on the instantaneous flow rate or flow velocity. It can be improved.

Furthermore, since the laser diode 151a of the dental laser device 150 is cooled by the air turbine driving air DA, the temperature rise of the dental laser device 150 itself is suppressed, so that the usability of the dental laser device 150 can be improved. It can be improved.
Further, by using the air turbine driving air DA for cooling the laser diode 151a, the cooling mechanism of the laser diode 151a can not only be simplified as compared with the case where cooling is performed using a Peltier element or the like. The size of the power supply 151 e can be reduced.

Furthermore, after the air turbine driving air DA supplied from the air turbine driving air supply passage 122a of the turbine hose 122 to the dental laser device 150 passes through the dental laser device 150, the air turbine of the turbine hose 122 By flowing into the driving air exhaust path 122d, the dental laser device 150 is not filled with the air turbine driving air DA, so that excessive air pressure is prevented from being applied to the air supply detection means 152 etc. The durability of the dental laser device 150 can be further improved.
Furthermore, since new air turbine driving air DA is always supplied to the dental laser device 150, the laser diode 151a is compared to the case where the air turbine driving air DA stagnates in the dental laser device 150. The cooling efficiency of the

  Furthermore, the dental laser device 150 can cool the affected area, remove stains and the like in the vicinity of the affected area, and the like by having the liquid ejection port 153 and the air ejection port 154.

As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited above.
For example, in the present embodiment, the dental laser device 150 is used by a dentist, but may be used by a dental hygienist or dental assistant.
Further, in the present embodiment, the dental laser device 150 is intended to treat dental hard tissue such as removal of dental caries and dental canal treatment and pain reduction of hypersensitivity, but the curing of the composite resin It may be for the purpose.
Furthermore, in the present embodiment, the instruments 130 are the air turbine 131, the micro engine 132, and the ultrasonic scaler 133, but the number and types of the instruments 130 are not limited to these.
Further, in the present embodiment, the dental treatment apparatus is the air turbine 131, but the dental treatment apparatus of the present invention is not limited to the air turbine, and any treatment apparatus may be used as long as it operates with compressed air. It may be
Further, in the present embodiment, the air hose is the turbine hose 122 which is attachable to and detachable from the air turbine 131, but the air hose of the present invention is not limited to the turbine hose and supplies compressed air to the dental laser device It can be anything that can be done, for example, a dedicated hose that supplies compressed air to the dental laser device.
Further, in the present embodiment, the power supply 151 e is a lithium ion battery, but may be a small generator.
Further, in the present embodiment, the water W and the air A ejected from the liquid ejection port 153 and the air ejection port 154 are intended to cool the affected area, but other purposes may also be achieved.
Further, in the present embodiment, the water W is jetted from the liquid jet port 153, but a chemical solution or the like may be jetted.

The air turbine driving air DA supplied to the air turbine main body 131a returns to the turbine hose 122 again after passing through the air turbine main body 131a.
Furthermore, the air turbine 131 has a liquid jet port 131c and an air jet port 131d for injecting water W and air A for cooling the affected area while cutting the affected area.

A turbine hose 122 extending from the work table 120 supplies the air turbine 131 with various fluids. That is, the turbine hose 122 supplies the air turbine driving air DA, the water W, and the air A to the air turbine 131, and recovers the air turbine driving air DA that has passed through the air turbine main body 131a. In other words, the turbine hose 122 has an air turbine drive air supply passage 122a, a water supply passage 122b, an air supply passage 122c, and an air turbine drive air exhaust passage 122d.
Further, a light source (LED) 122e is attached to the tip of the turbine hose 122, and a light beam L is emitted in the long axis direction.

The foot controller 140 is electrically connected to the work table 120, and transmits a control signal S corresponding to the operation on the foot controller 140 to a control unit (not shown) of the dental treatment unit 100. The control unit of the dental treatment unit 100 having received the control signal S adjusts the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 when the air turbine 131 is pulled out of the instrument holder 121.
When the micro engine 132 or the ultrasonic scaler 133 is removed from the instrument holder 121, the control unit in the work table 120 that receives the control signal S adjusts the amount of current supplied to each.

The dental laser device 150 is detachable from the turbine hose 122 in the same manner as the air turbine 131. The dental laser device 150 generates a laser beam and irradiates the patient with a laser irradiation mechanism 151, and an air supply detection unit 152 that senses air for driving an air turbine supplied from the turbine hose 122 to the dental laser device 150. And.
In the present embodiment, a pressure-sensitive element is used as the air supply detection unit 152, and the pressure in the flow path is detected by the pressure-sensitive element. It may be arranged.
Further, the dental laser device 150 further has a liquid jet port 153 and an air jet port 154 for jetting water W and air A for cooling the affected area while cutting the affected area.

  The dental laser device 150 has a substantially cylindrical shape, and a substantially cylindrical recess 150 a is formed on one end side, and the tip of the turbine hose 122 is inserted into the recess 150 a. Thereby, the dental laser device 150 is connected and communicated with the turbine hose 122.

As described above, the dental laser device 150 includes the laser irradiation mechanism 151 that generates a laser beam and irradiates the patient. The laser irradiation mechanism 151 includes a laser diode 151a that generates a laser beam, a heat sink 151b that abuts on the laser diode 151a to release heat generation of the laser diode 151a, and a laser conductor that a laser beam generated from the laser diode 151a passes. It has an optical path 151c, and a chip 151d connected to the exit side of the laser light guide 151c for irradiating the affected part with a laser beam.
The laser irradiation mechanism 151 further includes a power supply 151e for supplying power to the laser diode 151a, and a controller 151f for controlling the amount of power supplied to the laser diode 151a. In the present embodiment, the power supply 151 e is a lithium ion battery.

  The dental laser device 150 has a light guide path 155 through which the light beam L emitted by the light source 122 e of the turbine hose 122 passes. One end of the light guide path 155 is formed in the recess 150 a, and the other end is formed with a guide light irradiation port 156. Thus, the light beam L emitted from the light source 122 e of the turbine hose 122 is irradiated from the guide light irradiation port 156 onto the affected area, and the area around the affected area can be brightly illuminated.

  Further, the dental laser device 150 has a flow path for air turbine driving air DA, a flow path of air A, water W supplied from the turbine hose 122 and a flow path for discharging the air turbine driving air DA to the turbine hose 122 Have. That is, the dental laser device 150 includes an air turbine drive air introduction passage 157a, an air turbine drive air discharge passage 157b, a water flow passage 157c, and an air flow passage 157d.

All one ends of these flow paths are formed in the recess 150a. The other end of the air turbine drive air introduction passage 157 a and the other end of the air turbine drive air discharge passage 157 b communicate with the air chamber 158. That is, the air turbine drive air introduction passage 157 a and the air turbine drive air discharge passage 157 b communicate with each other via the air chamber 158.
The aforementioned heat sink 151 b is in contact with the air chamber 158. Thus, the heat generated by the laser diode 151a is dissipated to the air chamber 158 via the heat sink 151b.
In addition, a liquid jet port 153 is formed at the end of the water flow path 157c. Similarly, an air jet port 154 is formed at the end of the air flow path 157d.

  The air turbine drive air introduction path 157a is bifurcated in the middle, and an air supply detection means 152 is attached to one end.

  The tip 151d, the liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are formed on the tip side of the dental laser device 150 (the side opposite to the side on which the recess 150a is formed). The liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are disposed in the vicinity of the tip 151d.

Further, the opening positions of the light guide path 155, the air turbine drive air introduction channel 157a, the air turbine drive air discharge channel 157b, the water channel 157c, and the air channel 157d formed in the recess 150a are When the dental laser device 150 and the turbine hose 122 are connected, the light source 122e, the air supply path 122a for driving the air turbine, the water supply path 122b, the air supply path 122c, and the air exhaust for driving the air turbine It is located opposite to the passage 122d. That is, the opening of the light guiding path 155 faces the light source 122e, the opening of the air turbine driving air introduction path 157a faces the opening of the air turbine driving air supply path 122a, and the opening of the air turbine driving air discharge path 157b. The opening of the water flow path 157c faces the opening of the water supply path 122b, and the opening of the air flow path 157d faces the opening of the air supply path 122c.
Although not illustrated, the turbine hose 122 is provided with a plurality of sealing mechanisms. Thus, when the turbine hose 122 and the dental laser device 150 are connected, the air turbine drive air supply passage 122a, the water supply passage 122b, the air supply passage 122c, and the air turbine drive air exhaust passage 122d. And each is independent. Therefore, for example, leakage of water in the water supply passage 122b to the air turbine driving air supply passage 122a or the like is suppressed.

Next, the usage method and operation of the dental laser device 150 will be described using FIGS. 2 and 3.
As described above, the dental laser device 150 is removable with respect to the turbine hose 122 to which the air turbine 131 is usually connected. When using the dental laser device 150, the turbine hose 122 is removed from the air turbine 131 and connected to the dental laser device 150. At this time, the tip of the turbine hose 122 is inserted into the recess 150 a of the dental laser device 150.

Then, if it is desired to irradiate the affected area with a laser beam, the dentist steps on the foot controller 140. Thus, the air turbine driving air DA is supplied from the turbine hose 122 to the dental laser device 150 through the air turbine driving air supply passage 122a. The air turbine driving air DA supplied to the dental laser device 150 flows into the air turbine driving air introduction path 157a. Then, a part of the air turbine driving air DA is supplied to the air supply detection means 152 and the rest is supplied to the air chamber 158 by a branch provided in the air turbine driving air introduction path 157 a. Since air pressure is applied to the air supply detection means 152 by supplying the air turbine driving air DA to the air supply detection means 152, the air supply detection means 152 applies the air pressure to the dental laser device 150. It detects that the air turbine drive air DA has been supplied.
When the air supply detection means 152 detects the air turbine driving air DA, a detection signal is transmitted to the controller 151f, and the controller 151f energizes the laser diode 151a. Thereby, a laser beam is irradiated from the laser diode 151a, passes through the laser light guide path 151c, and is irradiated from the chip 151d toward the affected part.
At this time, water W is supplied from the turbine hose 122 to the dental laser device 150, and the water W passes through the water flow path 157 c in the dental laser device 150 and is jetted from the liquid jet port 153. Further, air A is also supplied from the turbine hose 122 to the dental laser device 150, and the air A passes through the air flow path 157 d in the dental laser device 150 and is jetted from the air jet port 154.

  On the other hand, the air turbine driving air DA supplied to the air chamber 158 passes through the air turbine driving air discharge path 157 b and is discharged to the air turbine driving air exhaust path 122 d in the turbine hose 122. Here, since the heat sink 151b is in contact with the air chamber 158, the heat of the laser diode 151a is conducted to the air chamber 158, so that the air for driving the air turbine DA passes through the air chamber 158, so that the laser diode The heat generation 151a can be conducted to the air turbine driving air DA. That is, the air turbine driving air DA can cool the laser diode 151a.

The foot controller 140 can also output a control signal S according to the stepping amount of the dentist. That is, the foot controller 140 does not output the simple ON / OFF binary value, but can output a plurality of values. When such a foot controller 140 is used, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 is also not a constant value, and a plurality of instantaneous flow rates can be supplied. In the present embodiment, as the foot controller 140 is depressed, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 can be increased.
The dental laser device 150 can also detect various instantaneous flow rates (in the present embodiment, air pressure) in addition to detecting simple ON / OFF binary values by the air supply detection means 152. Therefore, not only the binary values corresponding to ON / OFF from the air supply detection unit 152 but also various values from the air supply detection unit 152 are input to the controller 151 f. The controller 151 f can change the voltage applied to the laser diode 151 a according to the input value from the air supply detection means 152. In the present embodiment, as the value input from the air supply detection means 152 becomes larger (that is, as the foot controller 140 is depressed), the voltage applied to the laser diode 151a becomes larger, and the output of the laser beam becomes larger.

  The dental treatment unit 100 and the dental laser device 150 configured and operating in this manner are lasers by the dental laser device 150 according to the presence or absence of the air turbine driving air DA which is compressed air supplied to the dental laser device 150. By switching the irradiation and non-irradiation of the beam, it is not necessary to provide a dedicated foot controller for operating the dental laser device 150, so the foot of the dentist can be cleaned and the working environment can be improved.

  Furthermore, the output of the laser beam emitted from the laser irradiation mechanism 151 of the dental laser device 150 is adjusted according to the instantaneous flow rate detected by the air supply detection means 152, so that the laser can be operated only by the operation to the foot controller 140. Since the power of the beam can be changed, the usability of the dental laser device 150 can be improved.

  Furthermore, since the air supply detection means 152 is a pressure-sensitive element, it has a simple structure as compared with the case where the air turbine driving air DA is detected based on the instantaneous flow rate or flow velocity. It can be improved.

Furthermore, since the laser diode 151a of the dental laser device 150 is cooled by the air turbine driving air DA, the temperature rise of the dental laser device 150 itself is suppressed, so that the usability of the dental laser device 150 can be improved. It can be improved.
Further, by using the air turbine driving air DA for cooling the laser diode 151a, the cooling mechanism of the laser diode 151a can not only be simplified as compared with the case where cooling is performed using a Peltier element or the like. The size of the power supply 151 e can be reduced.

Furthermore, after the air turbine driving air DA supplied from the air turbine driving air supply passage 122a of the turbine hose 122 to the dental laser device 150 passes through the dental laser device 150, the air turbine of the turbine hose 122 By flowing into the driving air exhaust path 122d, the dental laser device 150 is not filled with the air turbine driving air DA, so that excessive air pressure is prevented from being applied to the air supply detection means 152 etc. The durability of the dental laser device 150 can be further improved.
Furthermore, since new air turbine driving air DA is always supplied to the dental laser device 150, the laser diode 151a is compared to the case where the air turbine driving air DA stagnates in the dental laser device 150. The cooling efficiency of the

  Furthermore, the dental laser device 150 can cool the affected area, remove stains and the like in the vicinity of the affected area, and the like by having the liquid ejection port 153 and the air ejection port 154.
