Physiotherapy Maneuver Is Critical to Recover Mouth Opening After Pediatric Trauma.

Purpose: A restricted mouth opening (MO) is predominantly a complication of maxillofacial trauma in pediatric patients and develops in 4 to 26.2% of cases. The purpose of the present study was to quantitatively investigate the influence of patient demographic data, fracture characteristics, and regular vigorous physiotherapy, with either voluntary or forcible MO exercises, on the recovery of a post-traumatic restricted MO in pediatric patients.

Evaluation of neoplastic nature of keratocystic odontogenic tumor versus ameloblastoma.

Objective: Although most of odontogenic tumors are benign, some of them will show locally destructive behavior, as keratocystic odontogenic tumor (KCOT) is now known as a benign but aggressive odontogenic neoplasm. The neoplastic characteristics in KCOT have been suggested from clinical as well as pathologic aspects. Matrix metalloproteinase-2 (MMP-2) is a gelatinase form of the MMPs family, which is a group of proteolytic enzymes that degrade many types of collagen.
