[Effect of the quality of endodontic treatment on the longevity of fixed prostheses. Apropos of 64 pulpectomies].

64 teeth with well-fitting post-retained crown were examined radio graphically and clinically and a number of failures were assessed including the peri-apical condition and the quality of root filling. All the teeth were vital and prosthetic was the only reason of endodontic treatment. Results have shown that 25% of the teeth had areas of radiolucency around the root apices. Various criteria parameters were reviewed for possible correlation to the failures. 15 out of the 16 cases of failures could be related to the endodontic therapy procedures: lack of using a rubber dam during the treatment and an unsatisfactory condensed and sealed root filling. Only one case was related to the deviation of post from the line of canal suggest a lateral perforation. To perform a post-retained crown the quality of endodontics must be considered: the operative procedures should be more controlled and enough time should be observed after root canal therapy to ensure its successful.

Traditional tea drinking in Senegal. A real source of fluoride intake for the population.

Tea drinking after meals is a traditional practice in Senegal where more than 80% of the population from 15 to 60 years old drink tea. According to the tradition, in one session, each tea consumer has to drink 3 cups of decocted tea. The content of a cup is about 30 ml of liquid. Some people drink tea three times daily, that is to say after each meal. Tea plant is rich in fluoride. To determine the effective intake of the Senegalese population from this source, we measured the fluoride concentration not only for each component of the prepared tea but also for each cup of prepared tea. For this study, we used the two main kinds of tea existing locally. The analyses have been done at Rochester, NY Eastman Dental Center, Oral Biology Dept Fluoride Laboratory using the Taves Microdiffusion Method and the fluoride Ion Specific Electrode. The results so that the mean total fluoride concentration of each cup, from the first to the third one, is: 4.0 mg F-/L, 7.436 mg F-/L and 1.230 mg F-/L. It means that on an average in one session, a Senegalese tea consumer has a daily fluoride intake of 1.139 mg F-/L when taking in count the total fluoride and drinking only 90 ml of tea. If we consider the ionic fluoride the amount of daily ingested fluoride for someone who takes only 3 tea-pots of 30 ml each, is 0.830 mg. To conclude, we state that this traditional practice may have a caries preventive effect. Further studies will be grateful for that practice when setting up a caries preventive program in our country. We will also be careful in extending that practice to children less than 8 years old because it might cause dental fluorosis as in Senegal the optimal dose of fluoride is 0.8 mg F-/L.

[Long term evaluation of results of endodontic treatments of dental pulp necrosis (74 cases obturated by the monoconal technique].

Various factors may affect the outcome of root canal therapy. In this study 74 endodontocally treated pulpless teeth were evaluated: (43 with periapical radiolucency and 31 without periapical lesions). These 74 non surgical treatment were performed in 60 patients (26 men and 34 women) by undergraduated students. The overall success rate was 71.62%; the rate of success for cases with no periapical radiolucency exceeded 80% whereas only 62.8% of the cases with perapical radiolucency had undergone partial resolution or complete resolution. Only 17.1% of lesions demonstrated complete radiographic resolution 12 to 16 months after the endodontic treatment. Reasons that may explain the low success rate are lake of asepty, root canal preparation and root canal filling technique.

The role of limb torque, muscle action and proprioception during closed kinetic chain rehabilitation of the lower extremity.

This paper defines the differences between open and closed kinetic chain exercise and explains the role of limb torque, muscle action, and proprioception during rehabilitation of the lower extremity. Closed kinetic chain rehabilitation is shown to decrease shear forces, increase proprioception, and increase muscle group coordination through examples of progressive exercises. The authors conclude that closed kinetic chain rehabilitation is an economical, efficient, and effective means of rehabilitation, with the ultimate goal of enhancing proprioception, thus gaining lower extremity joint stability.

[Clinical use of the Sonic Air MM 1500 and the Meca Sonic 1400 in canal preparation in endodontics].

INTRODUCTION: The preparation for canalisation has remained manual for a long time, technically constrictive and lasting for a long time. The application of ultrasound in Endontony allows us to tackle more calmly the canal course of the teath. The aim of this work is to make a qualitative comparison of the endosonic technique and the manual technique with reference to cases treated in the Dentisterie Opératoire clinic in Dakar. MATERIAL AND METHOD: 40 teeth of a complex canal anatomy and or in the posterior position in the buccal cavity were submitted to either a manual canalisation preparation or endosconic followed by monconic canal filling with a paste: 3 inc oxyde eugenol and iodoform. OPERATING FORMULA: Preparatory X rays: Allow us to evaluate the length of the work or the operating length after catheterisation: LO--length PRO, APEX RADIO-IMM LO--operating length PRO - occlusive point of reference The parietal support technique: The "synergetic" effect of ultrasonic oscillations of cavitation and of micro-acoustic currents associated with the action of the irrigation solution allow us to obtain canal incision. INSTRUMENTS: the pneumatic Sonic Air MM 1500; the Meca Sonic MMR 1400 coupled to a standard ISO motor; SHAPERS and Meca Shapers. Activated by shaper or Méca Shaper. Classic monoconic canal filling: Wadding paste + zinc oxyde paste-iodoform eugenol. X rays for orthocentric monitoring. RESULTS--DISCUSSION: In 60% of the cases treated, the patients presented with a complete dentition. The third inferior molar was in almost all the cases, the cause of the patient seeking a dental consultation. By endosonic treatment-conservation of teeth which would otherwise have been destined for extraction; biopulectomy or instituted pulpectomy for cases of desdodontite, endosconic amplication and canal sealing after the cooling of the inflammation. Duration of treatment: 2 sessions for gangrenous cases or desmodondite and one session for biopulpectomy or pulpectomy, with 4 sessions in 10% of the cases. Operation times: Saving of time of 40-50%. If a second session was necessary, 15-20 minutes was sufficient. Incidents or accidents during or after the operation: breakage of instruments, post-operative inflammatory reaction. CONCLUSION: better distribution of the irrigation solution, lessening of the risk of infection, better quality of the state of the canal surface, reduction in operating time, precision and reliability, conservation of teeth which would otherwise have been extracted, as many of the elements which encourages the appreciation of ultrasound in endodonty.
