Role of Prophylactic Dose of Oral Amoxicillin Trihydrate in Prevention of Bacteremia Post Surgical Removal of Impacted Mandibular Third Molar: A Clinical Study.

The current study is designed to evaluate the efficacy of pre-operative prophylactic antibiotic for prevention of bacteremia after surgical removal of impacted mandibular third molar SRIMTM. The study was carried out as an open clinical trial. Fifty patients who fulfilled the criteria were included. Twenty five randomly selected patients (study group) were administered two grams oral dose of amoxicillin trihydrate, one hour prior to the procedure. Twenty five patients (control group) were not administered any antibiotic prior to the procedure. All patients underwent surgical removal of impacted mandibular third molar through intraoral approach under local anesthesia. Blood culture for detection of aerobic and anaerobic micro-organisms was done for all 50 patients. Eleven out of the twenty five patients (44%) in the control group showed positive growth, including mixed growth (aerobic and anaerobic). Seven patients showed purely anaerobic, 2 patients purely aerobic and two mixed growth. In the study (antibiotic) group, 7 out of the 25 patients (28%) showed positive growth, including mixed growth. Three patients showed purely anaerobic, 2 patients purely aerobic and 2 mixed type of growth. The study suggests that the judicious use of antibiotic prophylaxis, in conjunction with optimal oral health care serves to minimize the adverse effects of antibiotic therapy; and at the same time reduce the significant morbidity and mortality associated with systemic infections that might occur due to bacteremia resulting from surgical procedures of the oral cavity.

A clinical tip for conservative retrieval of fractured abutment screw.

Fractures of the abutment screw are an extremely dreadful and taxing experience even for experienced clinicians. Retrieval of fractured screw segments due to excessive torque and improperly placed implants pose a great challenge to the clinician. The authors present a case wherein the fractured abutment screw was retrieved successfully with the help of an intraoral plastic mixing tip of light body putty material. The intraoral plastic mixing tips are a more readily available, cost-effective, and feasible alternative to other means of screw retrieval like ultrasonic scalers, endodontic files, and screw retrieval kits.

Distraction Osteogenesis as a reliable method in management of Obstructive Sleep Apnoea (OSA) secondary to TMJ Ankylosis: A Case Report.

Obstructive sleep apnoea (OSA) is identified as repetitive and intermittent upper airway collapse or narrowing during sleep. Skeletal advancement through maxillomandibular surgery remains the most effective surgical treatment for OSA but is radical with certain relapse rate. Distraction Osteogenesis of mandible is a single-jaw surgical treatment alternative to bi-jaw surgeries having lesser complications. This case report describes successful management of a 46-year-old patient who reported with a chief complain of obstruction in breathing while sleeping since one year. Obstructive Sleep Apnoea (OSA) secondary to a retrognathic mandible was the final diagnosis, which was successfully treated by Distraction Osteogenesis (DO) of the mandible. The case showed enhancement in airway by 13mm and marked forward movement of Point-B (SNB increased by 6 degrees). The Epworth Sleepiness Scale value decreased from 19mm to 8 mm indicating substantial increase in the airway with stable results after 18 months of follow-up (elimination of symptoms and subsequent sound sleep). Distraction osteogenesis is an effective and reliable method to treat obstructive sleep apnoea secondary to retrognathic mandible.
