Adaptation of dental instruments for periodontal purposes.

Modification of instruments used in general dentistry can make them useful in periodontal therapy. A periosteal elevator, a rongeur and instruments for cutting and carrying small particles of bone for grafting procedures have been described.

A set of silver dental instruments from the New Milton Collection.

This short paper studies a set of ten silver instruments belonging to the New Milton Collection, which are believed to be dental and of Roman date. A brief history of the set is given, also a description of each instrument together with suggested name and function, based upon the accounts of dental procedures recorded in classical medical texts. In an attempt to determine the antiquity of the set, results of non-destructive tests upon two of the instruments are compared with those of metal artefacts of authenticated date. In addition, stylistic comparisions are made with ancient instruments in museum collections, and representations of instruments upon ancient stelae and in medical manuscripts.

[Use of a microwave device for dental instrument sterilization: possibilities and limitations].

BACKGROUND: The aim of the present study was the evaluation of the effectiveness as sterilizer of a modified version of a microwave device, which was previously tested by the same authors and found unsatisfactory. MATERIALS AND METHODS: Dental mirrors were contaminated by 10(4)-10(9) microorganisms of Stapbylococcus aureus and spores of Bacillus subtilis and Bacillus stearothermophilus. The inocula used were both wet and dry. The duration of the treatment was 4 minutes. Three series of tests were made: 1) microwaves and "adjuvant" solution (as suggested by the producer of the device); 2) microwaves only (in place of the "adjuvant" solution, a Na Cl 0.9% was used); 3) "adjuvant" solution only (into an oven at 25 degrees C). RESULTS: In the 1st and 3rd series of tests all the microorganisms and the spores were killed. In the 2nd series of tests a bactericidal effect against some, not all, microorganisms of the S. aureus species and against spores of B. subtilis and B. stearothermophilus was found. CONCLUSIONS: The results of this study suggest that the device tested has a sterilizing activity, which, however, is not due to the activity of microwaves only; but to the combined activity of microwaves, "adjuvant" solution and temperature (since inside the device, at the end of the treatment the temperature on the mirrors was 94 degrees C).

[Effect of certain methods of sterilization on the quality of dental instruments].

Comparative investigations of the sterilizing action produced on the stomatological instruments by 4 chemical bactericidal agents and hot air tend to give preference to sterilization with a 2% solution of glutamic acid in a combination with a 70% isopropyl alcohol at a 45 minutes long exposure. Such a sterilization does not cause any corrosion of the instruments and reduces to a lesser degree the resistance of the cutting edges than in the case of sterilization with hot air.

[Sterilization of dental instruments].

Instruments used by dentists are often sterilized with steam sterilization. At this moment three types of processes are described in the European norms: Type N, S and B. According to the norms type N can be used for non-wrapped non-hollow instruments and non-porous instruments, type S can be used for instruments specified by the manufacturer and type B can be used for wrapped, hollow and porous instruments. The principles on which the sterilizors are based are described. It is concluded that before purchasing the sterilizor the method of working and instruments to be sterilized must specified. In most cases a type B process is preferable in order to gaurantee to be certain to have an effective and reproducible process.

[Ancient dental instruments that remain in use today].

Forceps for extraction, scrapers, elements for removing decayed tissue, preparation and obturation of cavities, have all resisted time passing by. And many of these elements, exhibited in museums for their antiquity, are still being used, though perfected and made of lighter materials.

[Dental instrument as foreign body in the air-passage].

A case report on a Kerr-broach aspirated to the left bronchial tree is presented. The broach was removed with difficulties using bronchoscope and forceps. The use of rubber dam is advocated in endodontic therapy. A scheme to handle foreign bodies in the bronchial tree is outlined involving immediate X-ray and removal by an experienced endoscopist.

[Hardening of dental instruments].

The possibility of prolonging the service life of stomatological instruments by the local hardening of their working parts is discussed. Such hardening should be achieved by using hard and wear-resistant materials. The examples of hardening dental elevators and hard-alloy dental drills are given. New trends in the local hardening of instruments are the treatment of their working parts with laser beams, the application of coating on their surface by the gas-detonation method. The results of research work and trials are presented.
