Abstract
Abstract The present invention describes a hollow irrigation probe consisting of two parts: a rigid, straight or bent, metal or plastic arm with a proximal connection hub such as a luer lock or luer connection or threaded hub or other connection element; and a short, flexible, plastic distal end with a blunt tapered or round tip. Said flexible part is fixed to the arm by means such as chemical bonding, glue, welding or insert molding or plasma etching or mechanical lock. The probe lumen opens at the center of the tip or laterally at some distance from the tip. The probe according to the present invention constitutes the end of pumping devices reaching the patient's body engineered for the delivery of antibiotic/antiseptic or other physiologic and medically compatible solutions. These devices include different manual and automatic syringes, spray injectors and mechanically/electrically driven pump systems. Said flexible end part is designed for the atraumatic penetration into the gingival sulcus/periodontal pockets. The rigid arm enforces the flexible end into the space between the gum and tooth.
It is possible to design multiple arm shapes (and sizes) to facilitate accessibility to various teeth and tooth aspects.
The new probe according to said invention is designed for use by professional and nonprofessional personnel including patient self treatment.

Description
FLEXI~3LE-END IRRIGATION PRO~E
sack~round of the Invention The present invention xelates to a hollow periodontal irrigation probe device for the delivery of any antibiotic/antiseptic or other physiologic and medically compatible solutions into a periodontal pocket or the gingival sulcus.
Prior ~rt The periodontal pocket is a pathologic space formed between the soft gum tissue and tooth root as a result of the destruction of the tooth supporting alveolar bone and periodontal ligament. This space opens to the oral cavity and is populated by pathogenic bacterial species (M.A.
Listgarten, J. Periodontol. 47:1-18, 1976). These bacteria cause further destruction of the tooth attachment apparatus leading eventually to tooth loss. Thus, the aim of all curative and preventive periodontal treatments is to arrest the initiation and progression of tissue destruction by removal of the pathogenic flora. Removal of the pathogenic flora from the pockets cannot be achieved by conventional oral hygiene measures which have a limited subgingival effect (P. Kho, F.C. Smales, J.M. Hardie, J. C1in. Periodontol.
12:676-688, 1985). One approach to this problem, widely used over the last decades, has been surgical pocket elimination.
207013~
This procedure is costly, often results in considerable pain and discomfort and in the lon~ run is characterized by a limited success rate. In mammals, particularly dogs and cats, where periodontal disease is the number one cause of tooth loss (B. Colomery 3d P. Frost, Vet. Clin. North Am.
Small Anim. Pract. 16:817-833, 1986) the treatment consists of periodical scaling of dental sulrus that involve general anaesthesia and incubation (S.M. Marretta, Semin. Yet. Med.
DSurg. Small Anim. 2:230-240, 1987). Recently, evidence that control of periodontal disease can be achieved without pocket elimination has been established (S.P. Ramfjord, J. Am. Dent.
Assoc. 114:37-40, 1987). One such nonsurgical approach is the local administration into the pocket of antibiotics and antiseptics alone or in combination with mechanical debridement of the pocket. The simplest technique for such administration is repeated subgingival irrigation using the respective solutions. This is done using a delivery device e~uipped with a conventional blunt, rigid, metà~ needle (L.L.
Soh, H.N. Newman, J.D. Strahan, J. Clin. Periodontol. 9:66-74, 1982; J.G.L. Khoo, H.N. Newman, J. Periodont. Res.
18:607-619, 1983). With this type of needle the device is operated effectively only by trained personnel. To avoid the risk of traumatizing the soft tissue pocket wall and epithelial attachment as well as the discomfort involved in tooth sensitivity resulting from the contact of the root with metal, the sel~-administered ~by the patient) use is limited to buccal aspects of single-rooted teeth which constitute relatively accessible sites ~L. Braatz, S. Garret, N.
Claffey, J. Egelberg, J. Clin. Periodontol. 12:630-638, 198~). This limitation on patient-administered irrigation of antibacterial solutions results from the needle rigidness and associated traumatizing potential as well as the use of only one form of bending. It is rather surprising that an atraumatic probe with a non metallic end of appropriate shapes and dimensions, is not yet known for the purpose of subgingival irrigation in men and small animals (mammals).
