ABSTRACT
In highly decomposed and mutilated dead body remains dentures are frequently sent for the medicolegal examination by the forensic experts for identification. Dental tissues like bones resist putrefaction for much more longer period and these are in many cases available for examination due to its tough texture and ability to escape destruction. Methods: The present prospective study was done on 450 subjects (225 males and 225 females) of known age and sex, from different socio-economic strata and religion belonging to north region of Bihar state. Their age ranges vary from 14-73 years. The mandibular and maxillary canines of both sides were measured in both sexes. Various dimensions namely, mandibular and maxillary canine crown width, crown length and canine separation width were taken in each case with the help of dividers and vernier calipers with a resolution of 0.1mm. Results: In the present study, regarding mandibular canines in males, crown length showed the maximum accuracy (92.0%) of sex identity in the age group (E) 54-63 years and canine separation width showed the minimum accuracy of 40% in the age group (D) 44-53 years. In females, crown width showed the maximum accuracy of 83.33% in the age group (D) 44-53 years and minimum accuracy of 30% by crown length in the age group (F) 64-73 years. Regarding the maxillary canines, in males, the crown length showed the maximum accuracy (90%) of sex identity in the age group (D) 44-53 years and the minimum accuracy of 44% in the age group (A) 14-23 years. In females, both crown width and crown length showed the maximum accuracy of 96.66% in the age group (D) 44-53 years and minimum accuracy of 22% by crown width in the age group (B) 24-33 years. Conclusion: The present study revealed this method could be useful as a reliable tool for sex identity when use of other methods are not possible or there is no definite features indicating the sex as in cases when parts of decomposed and skeletonised dead bodies are recovered after a mass disaster or exhumation and also in cases when smaller fragmented part of the body is only available for examination.
ABSTRACT
Purpose: The purpose of this clinical study was to evaluate the functional restoration by interpositional arthroplasty with temporalis myofascial flap in temporomandibular joint ankylosis. Methods: After obtaining consent, the procedure were explained to the patient and each of the patients who met the inclusion criteria of the present study were randomly selected. Preoperatively all required investigations were done, fitness opinion for surgery and general anaesthesia was obtained, preoperative mouth opening / interincisal distance was measured with calliper, occlusion recorded, and midline shift was assessed. Surgical procedure (interpositional arthroplasty with temporalis myofascial flap) was carried out under general anaesthesia with endotracheal intubation. And patient was followed for about six months and following parameters were recorded. Mouth opening / interincisal distance, occlusion, Midline shift, Pain and Diet (solid/liquid). Results: In the present study, the temporalis myofascial flap was evaluated to be efficient in preventing the reankylosis. Preoperatively the mean interincisal opening was 6.93mm and post-operatively after a period of 6 months follow-up it remained as 34.93mm. Conclusion: The temporalis myofascial flap is an efficient interpositional material. It is a biologic, autogenous tissue, so there is no question of any rejection. The results of this study indicate that the use of temporalis muscle and fascia flap is effective in treating TMJ ankylosis.
