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.

A descriptive cross-sectional study was conducted among 96 dental surgeons at selected private dental hospitals in Dhaka city (North). The objective of the study was to find out musculoskeletal disorders within dental surgeons at selected private dental hospitals in Dhaka city during the period between September to November 2012.Convenient sampling technique was used and information was gathered by face to face interview with a pre tested semi structured questionnaires. Among the respondents, 43.8% were of in the age group of 36 - 40 years age, 18.8% were in the age group of up to 35 years, and 13.5% were in the age group of 41 45 years and 19.8% in the age group of over 50 years. The 67.7% were male and 32.3% were female respondents. By professional educational level 36.4% were Bachelor in Dental surgery and 63.5% were post graduated. . Among the respondents 79.2% who had professional experience more than 10 years missing in practice due to MSD more than 29.2%who had professional experience more than 10 years or less. The reduction and prevention of MSDs among dental surgeons should include their education and awareness regarding the importance of work related risk factors.

The aim of this study is to compare the tissue response between the ridgelap pontic and modified ridgelap pontic. Total patients were 40. The fixed prosthesis were cemented by temporary cementing material. After providing the treatment, instruction on maintenance of prosthesis. Patients were visited and studied after 6 weeks, 12 weeks and 6 months to observe the condition of tissue response beneath pontic. The following necessary data were collected in respect of the condition of tissue beneath the pontic, color of gingiva. The modified ridgelap pontic is better than ridgelap pontic regarding tissue response. The tissue response with the ridgelap surface of the pontic of fixed partial denture in 1st molar missing tooth enhanced the condition of the mucous membrane beneath the tissue surface of the pontic, condition of the abutment tooth, between ridge surface of the pontic and mucosa overlying the edentulous ridge achieved better success regarding fixed partial denture.

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.

Pyogenic granuloma is one of the inflammatory hyperplasia seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low- grade local irritation, traumatic injury or hormonal factors. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manifesting as small, red erythematous papules on a pedunculated or sometimes sessile base, which is usually hemorrhagic. The surface ranges from pink to red to purple, depending on the age of the lesion. Because of the high frequency of pyogenic granuloma in the oral cavity, especially during pregnancy, and necessity for proper diagnosis and treatment, a complete information and investigations about this lesion, in addition its treatment is presented. The study emphasizes the clinical follow-up after the treatment of patients that present pyogenic granuloma. Follow-up over 19 months of surgical procedures demonstrated the maintenance of a periodontal health decreases the chances of recurrence.

This case report describes a case of avulsed left maxillary central incisor tooth which was replanted in the dental office. The tooth was gently rinsed of any debris and placed in normal saline during the examination and preparation of the replantation socket. The tooth was replanted and functionally splinted. The following week the tooth was opened for pulp extirpation and placement of calcium hydroxide. Two weeks later, the root canal was filled with gutta-percha and zinc oxide eugenol sealer, and the access cavity was restored with a bonded composite restoration; the splint was removed. Two year clinical and radiological follow up of the case showed ankylosis and infraocclusion of the replanted tooth

Basal cell carcinoma (BCC) is the most common form of skin cancer. BCC in the head and neck usually presents as a slow growing well defined papule or nodule located above the line connecting the angle of the mouth and ear lobe. It is locally destructive lesion and cause serious disfigurement but metastasizes rarely. Various treatment are available out of which surgical excision is the most standard option. Surgical excision of tumors from the face may create a defect that is difficult to restore. Skin grafts can only cover superficial defects and has a natural tendency to contract and may not take properly. Also, because of the color mismatch, it is not cosmetically identical to the face. The use of regional flaps such as rotational cheek flap can be a very good option for the reconstruction of a moderate to large cheek defect. Herein, we report a case of large BCC over the face for which rotational cheek flap reconstruction was carried out at Modernized Sadar Hospital, Chapainawabganj.
