Background: To determine the most common position of both mental foramen in selected Bangladeshi population. Materials and Methods: This was a cross sectional study. Convenient sampling technique was used. For this seventy five panoramic radiographs of Bangladeshi population were taken from Out Patient Department of MH Samorita dental unit, Dhaka, Bangladesh. Result: The most common Horizontal position of the mental foramen was in line with second premolar (position 4). In vertical axis, the location of MF in lower half of body of mandible was found in all OPGs (100%). Conclusion: The knowledge about the position of the mental foramen may be helpful to the dental surgeons to achieve full anesthesia after nerve block.

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.

Aims:This was a cross-sectional study done in the City Dental College, Malibagh, Chowdhurypara. The objective of the study was to assess the level of knowledge about HIV/AIDS among the final year dental students during the period between April to June 2012. Materials and Method:Convenient sampling technique was used and a total of 77 final year dental students were included. A pretested questionnaire was used in English and information was gathered by face to face interview regarding demographic characteristics and HIV/AIDS related knowledge which contained; meaning of HIV/AIDS cause of HIV/AIDS, mode of transmission, risk group, preventive measure. Result:The data were analyzed by computer software SPSS version 17. The study showed that 23.4 percent of the respondents had poor knowledge on HIV/AIDS. About 18.1% know that AIDS can be transmitted if having sexual contact with HIV positive case. Moreover, 13.8% have knowledge about HIV contaminated blood transfusion, 15.1% have knowledge about HIV infected mother to child, 14.6 % know that HIV infection can cause by pricking an infected needle and 10.5% know that it can transmit through body fluids like blood; semen etc. 45.1% had knowledge about injury by infected surgical instrument. Conclusion:The study revealed that the relationship between the knowledge of HIV/AIDS among dental students and sex of the respondents is statistically significant. It is evident that even in the second decade of the AIDS epidemic, final year dental students continue to have a lack of proper knowledge about HIV/AIDS. Training Programme should be arranged on HIV/AIDS for the dental students during clinical attachment. DOI: http://dx.doi.org/10.3329/updcj.v2i2.15531 Update Dent. Coll. j: 2012; 2 (2): 23-27

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 toothUpdate Dent. Coll. j: 2015; 5 (1): 30-34

Background: Nonsquamous cell malignant tumors of jaw and oral soft tissue are rare constituting between 6%-10% of all malignancies in the region. A few case reports of individual tumors are available while reviews of significant series is lacking. This report presents 22 cases of Nonsquamous cell malignant tumors collected over 8 months at a tertiary oral care centre in Dhaka, Bangladesh. Objective: To find out the distribution & pattern of oral nonsquamous cell malignant tumors among all oral malignancy and to find out the age, sex, site, clinical presentation, the histological types of these tumors. Method: This descriptive cross sectional study was done in Oral and Maxillofacial Surgery Department, Dhaka Dental College and Hospital.The entire patient histopathologically diagnosed as any type of Nonsquamous cell tumor were selected. Data were collected in a summarized data sheet. Then histopathological types of them were analyzed to indicate the distribution according to age, gender, site and clinical presentation. Result: There were 107 Oral malignancies of which 22(20.56%) were Nonsquamous cell malignant tumors which is significant in comparison to Squamous cell carcinoma in Bangladesh. Among the respondents, 9(40.91%) were diagnosed as minor salivary glands malignant tumors, 7(31.2%) were diagnosed as sarcomas, Malignant melanoma were 4(18.18%) and Non- Hodgkin’s lymphoma were 2(9.09%). The male to female ratio was 1:1.2 with ages were between 9 years to 70 years old (mean age 35.45 ± 21.76 years) with most patients (36.36%) in 16 to 30 years of life. Cases presented with symptoms such as swelling (100%), pain, paresthesia, loose tooth and tissue ulceration. Conclusion: In Dhaka Dental College Hospital, nonsquamous cell malignant tumors account for 20.56% of all oral malignancies among them minor salivary glands malignant neoplasm and malignant melanoma were the predominant type. Most affected were people in the 2nd and 3rd decades of life with no sex predilection. Most common site of involvement was maxilla. The need for improved medical awareness, diagnostic facilities and upgrading of infrastructure was stressed. DOI: http://dx.doi.org/10.3329/updcj.v3i2.17997 Update Dent. Coll. j: 2013; 3 (2): 34-38

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.

This case report describes the Indirect Pulp Treatment (IPT) of deep carious lesion in a permanent molar with Ledemix. A 18 years old male patient reported discomfort associated with thermal stimulation on the mandibular right first permanent molar. Radiographically revealed a deep buccal carious lesion, very close to the pulp. periapical radiolucency and periodontal space thickening was absent. Pulp sensitivity was confirmed by thermal pulp vitality tests. Based on the main complaint and the clinical and radiographic examinations, the treatment plan was established to preserve pulp vitality. Clinical procedures consisted of removing the infected dentin and lining the caries-affected dentin with ledermix cement, the tooth was restored with composite cement. After 12 month followup, no clinical or radiographic pathological findings were found.
