Description

Oppfinnelsen vedrører pellets, bestående av et The invention relates to pellets, consisting of a

elastisk, åpenporet mykskum til anvendelse i dentaldiagnostikken, elastic, open-pore soft foam for use in dental diagnostics,

idet pelletene er karakterisert ved at de har en volumvekt fra 25 til hO kg pr. m^ og et poretall fra 10 til 20, fortrinnsvis as the pellets are characterized by having a volume weight of from 25 to hO kg per m^ and a pore number from 10 to 20, preferably

15 til 19 porer pr. cm . 15 to 19 pores per cm.

Innen den tannlegemessige diagnostikk inntar fast- Within dental diagnostics, fixed-

slåelse av pulpas levetilstand en sentral stilling. Ved siden av elektrotestfremgangsmåter og anvendelse av karbonsyresne har i den senere tid også kjølemidler som eksempelvis difluordi- striking the pulp's living condition a central position. In addition to electrotest methods and the use of carbonic acid snow, cooling agents such as difluorodi-

klormetan funnet inngang i tannlegediagnostikk. Anvendelsen av dette midlet sikrer en meget høy diagnosenøyaktighet ved dir- chloromethane found its way into dental diagnostics. The use of this agent ensures a very high diagnostic accuracy when dir-

ekte besprøytning av tannen som skal prøves. En slik direkte besprøytning er først å gjennomføre når en forutgående tusjer- real spraying of the tooth to be tested. Such direct spraying can only be carried out when a previous

ing av tannen med kjølemidlet forløper negativt. Ved tusjering sprøytes kjølemidlet på en pellet som etter sin gjennomtreng- ing of the tooth with the coolant proceeds negatively. When douching, the coolant is sprayed onto a pellet which, after its penetration

ning med en gang bringes i kontakt med tannen. Por denne in- ning is immediately brought into contact with the tooth. Por this in-

direkte metode egner det seg ikke cellulose- eller vatt-tamponger, direct method, cellulose or cotton swabs are not suitable,

som som kjent er vanlige i tannlegepraksis i årtier da den kan fryse fast på tannkronen, hvorved pasienten med en vital tann gis unødige smerter. Det ble derfor for dette formål eksempel- which, as you know, have been common in dental practice for decades as it can freeze to the crown of the tooth, whereby the patient with a vital tooth is given unnecessary pain. It was therefore for this purpose example-

vis anvendt fleksible pellets av polyuretan på polyesterbasis med en volumvekt på ca. 20 kg/m'' og med et poretall på ca. 25 ± 2/cm . Disse pellets bevirker etter deres gjennomfuktning med difluordiklormetan under tusjeringen av tannoverflaten et temperaturfall på 50°C i løpet av 0,8 sekunder. Termometriske in-vitro-prøvinger ved hjelp av Servogor-II-kompensasjonsskriver viser at varmefjerningen på tannoverflaten vedvarer for ca. show used flexible pellets of polyurethane on a polyester basis with a volume weight of approx. 20 kg/m'' and with a pore number of approx. 25 ± 2/cm . These pellets cause a temperature drop of 50°C within 0.8 seconds after they are wetted with difluorodichloromethane during the brushing of the tooth surface. Thermometric in-vitro tests using the Servogor-II compensation printer show that the heat removal on the tooth surface persists for approx.

15 sekunder. Disse nevnte pellets har den ulempe at etter rela- 15 seconds. These mentioned pellets have the disadvantage that after rela-

tivt kort tid må det foregå en ny gjennomfuktning med kjølemidlet. within a very short time, a new thorough moistening with the refrigerant must take place.

Ved anvendelse av pellets av polyuretan på polyeterb.asis gjør When using pellets of polyurethane on polyetherb.asis do

også deres statiske oppladning seg uheldig merkbart som fører til also their static charge itself unfortunately noticeable which leads to

en sammenklumpning av pelleten. a clumping of the pellet.

Overraskende ble det nå funnet at ved anvendelse av et skumstoff av volumvekt fra 25 til 40 kg/m^ og som har et poretall fra 10 til 20/cm , kan med en pellet av samme volum og gjennomfuktet med samme mengde kjølemiddel omtrent det dobbelte antall tenner behandles. Som skumstoffer egnet for pelletene ifølge oppfinnelsen har det vist seg slike som har en volumvekt fra 25 til 40 kg/m^, spesielt imidlertid fra 30 til 35 kg/m 3 , fortrinnsvis på 33 kg/m 3. Poretallet ligger mellom ca. 10 til 20, fortrinnsvis mellom 15 til 19, spesielt ved 17 ± 2/cm . Som spesielt egnet har det vist seg skumstoff av polyuretan på polyesterbasis ("Moltopren"). Ved anvendelse av dette spesielle skumstoff ble det oppnådd spesielt gode resultater, når det har en volumvekt på ca. 33 kg/m"<1> og et poretall på ca. 17 ± 2 porer/cm . Et slikt skumstoff viste overraskende heller ikke den ved de kjente pellets opptredende sammenklumpning. Surprisingly, it has now been found that when using a foam material of volume weight from 25 to 40 kg/m^ and which has a pore number from 10 to 20/cm , with a pellet of the same volume and soaked with the same amount of refrigerant, approximately twice the number teeth are treated. Foam materials suitable for the pellets according to the invention have been found to have a volume weight of from 25 to 40 kg/m^, especially however from 30 to 35 kg/m 3 , preferably of 33 kg/m 3. The pore number is between approx. 10 to 20, preferably between 15 to 19, especially at 17 ± 2/cm . Polyurethane foam on a polyester basis ("Moltopren") has proven to be particularly suitable. When using this special foam material, particularly good results were achieved, when it has a volume weight of approx. 33 kg/m"<1> and a pore number of approx. 17 ± 2 pores/cm . Such a foam surprisingly also did not show the clumping that occurs with the known pellets.

Det må videre anses som overraskende at pelletene ifølge oppfinnelsen, bestående av et åpenporet elastisk mykskum muliggjør behandlingen av et større antall tenner etter at det på grunn av poretallet kunne ventes at det ville foregå en hur-tigere fordampning av kjølemidlet sammenlignet med de kjente pellets. It must also be considered surprising that the pellets according to the invention, consisting of an open-pore elastic soft foam, enable the treatment of a larger number of teeth after it could be expected due to the pore number that a faster evaporation of the coolant would take place compared to the known pellets.

Pelletene ifølge oppfinnelsen kan spesielt anvendes for behandling av tenner. Det er også mulig med dem å behandle svellinger, traumatiske hud- og muskelirritasjoner osv., på hud og slimhud. The pellets according to the invention can especially be used for the treatment of teeth. It is also possible with them to treat swellings, traumatic skin and muscle irritations, etc., on the skin and mucous membranes.

Som kjølemiddel kommer det spesielt i betraktning halogenalkaner som eksempelvis monofluortriklormetan, difluordiklormetan, tetrafluordikloretan ("Prigene") eller eksempelvis også anvendelse av karbonsyresne. Halogen alkanes such as monofluorotrichloromethane, difluorodichloromethane, tetrafluorodichloroethane ("Prigene") or, for example, also the use of carbonic acid snow, are particularly taken into consideration as refrigerants.

Som skummaterial er det spesielt med hensyn til den uteblivende sammenklumpning egnet anvendelse av et polyuretan på polyesterbasis. Det kan imidlertid også anvendes andre skummaterialer, eksempelvis en gelatinsvamp, oksycellulosesvamp eller også en polyuretansvamp på polyeterbasis. As a foam material, the use of a polyester-based polyurethane is suitable, especially with regard to the non-clumping. However, other foam materials can also be used, for example a gelatin sponge, oxycellulose sponge or also a polyurethane sponge on a polyether basis.

Skumstoffenes fremstilling foregår på i og for The production of the foams takes place inside and out

seg kjent måte for polyuretansvamper eksempelvis ved det fra polyisocyanatkomponenter ved tilsetning av vann dannede opp-skumningsbevirkende karbondioksyd. known way for polyurethane sponges, for example by the foaming carbon dioxide formed from polyisocyanate components by the addition of water.

Pelletenes form kan varieres meget. De må i sin størrelse være tilpasset tannet som skal behandles. Med hensyn til størrelsen er det å unngå at ved behandlingen fuktes sam-tidig også de ved siden av liggende tenner med kuldemidlet. Hensiktsmessig har pelletene følgelig en søyleformet form, idet bunnflaten hensiktsmessig også kan være utformet traplsformet (sammenlign figur 1). Det er eksempelvis også mulig å gi en pellet ifølge oppfinnelsen form av en firkantet søyle (sammenlign figur 2), hvis søyle utgjør ca. 8 mm, med sidelengder av grunnflaten på ca. 6 og 3 mm. Er grunnflaten eksempelvis utformet trapesaktig (sammenlign figur 1), så kan trapésets høyde eksempelvis utgjøre ca. 8 mm, lengden av de to parallelt for-løpende sider ca. 3 og 7 mm. En søyleformet pellet kan også The shape of the pellets can be varied widely. Their size must be adapted to the tooth to be treated. With regard to the size, it is to be avoided that the adjacent teeth are also moistened with the coolant during the treatment. Appropriately, the pellets consequently have a columnar shape, as the bottom surface can also suitably be designed in a trapezoidal shape (compare figure 1). For example, it is also possible to give a pellet according to the invention the shape of a square column (compare Figure 2), whose column amounts to approx. 8 mm, with side lengths of the base of approx. 6 and 3 mm. If the ground surface is, for example, trapezoidal (compare Figure 1), then the height of the trapezoid can be, for example, approx. 8 mm, the length of the two parallel sides approx. 3 and 7 mm. A columnar pellet can too

ha en sirkelformet grunnflate med en høyde på eksempelvis 6 mm og en diameter på ca. 3 - 6 mm (sammenlign figur 3). Por å lette behandlingen anvendes fortrinnsvis slike pellets som har en trapesformet grunnflate. Anvendelsen av pelletene foregår således at det holdes med en pinsett og sprøytes med kjølemidlet, fortrinnsvis fra en aerosolflaske så lenge (ca. 3 sekunder) fra en avstand på ca. 2 cm, inntil det er fastslåbart en maksimal metning ved avdrypning. Umiddelbart deretter påtrykkes den tannen som skal undersøkes. have a circular base with a height of, for example, 6 mm and a diameter of approx. 3 - 6 mm (compare figure 3). In order to facilitate processing, such pellets are preferably used which have a trapezoidal base surface. The pellets are used so that they are held with tweezers and sprayed with the coolant, preferably from an aerosol bottle for as long (approx. 3 seconds) from a distance of approx. 2 cm, until a maximum saturation can be determined by draining. Immediately afterwards, the tooth to be examined is pressed on.
