Purpose of this study was to investigate the most common accurate position of the mental foramen in selected Bangladeshi population which helps in several clinical procedure and nerve block anesthesia.The study sample included one hundred and one panoramic radiographs of selected urban population of Bangladesh taken in Out Patient Department, Update Dental College, Dhaka, Bangladesh. The most common Horizontal position of the mental foramen was below the root of second premolar tooth (37.6%). In vertical axis, the location of MF in lower half of body of mandible was found in all OPGs (100%).In vertical distance, Position B, which is measured by distance between 1.0 mm to 1.5 mm,is the most common position of MF in all aspect as viewed in OPGs in Bangladeshi population.In this study, the difference of the location of the mental foramen in different ethnics groups was discussed. Clinicians and anthropologists should expect to find the position of the mental foramen to be symmetrical and below the root of second premolar tooth.Update Dent. Coll. j: 2015; 5 (1): 03-09
An extremely uncommon tooth developmental anomaly seen such as bilateral primary mandibular first molar with a single root and single canal. Various researchers found that due to failure of invagination of HERS leads to various anomalies in root morphology. A 9 year old girl with pain on lower left side of the jaw originated from mandibular left first molar. On right side there was also presence of 84 with single root. The tooth was treated by pulpectomy followed by restoration. Due to unusual morphology, the chance of endodontic mishaps is extremely high in the search of additional canal, which can be overcome by proper knowledge of root morphology and radiographic interpretation.

Aim: To seal with Mineral trioxide aggragate(MTA) and make a sizeable communication between the root canal system and the periradicular tissue and provide a barrier because of lack of apical constriction.Summary: A 9 year old girl who had met with trauma about six years ago, before she visited department of Paediatric Dentistry , Update Dental College,Dhaka,Bangladesh for the treatment of mandibular right lateral incisor. The case was diagnosed as necrosis of pulp with open apex. After proper isolation access opening and biomechanical preparation was performed with 1mm short of the radiographic apex and calcium hydroxideused as intra canal medicament. After 15 days MTA was placed in the canal till a barrier of 4mm was achieved. Later obturation was done using lateral condensation technique.Size of the periapical lesion was almost decreased after one year of follow up. Followup was done after 1 month, 6 months and 1 year later.Update Dent. Coll. j: 2015; 5 (1): 21-25
