BackgroundDespite remarkable reduction in the prevalence of dental caries in developed countries, dental caries is still a highly prevalent disease among children in developing countries. Objectives To estimate the oral health status of children under five years of age by assessing decayed, missing and filled teeth (dmft) status of primary teeth along with their tooth cleaning and food habits. Materials and MethodsThis cross-sectional study on oral health status of children under five years of age was carried out among 107 children attending the Outpatient Department of Sapporo Dental College and Hospital, situated at Uttara, Dhaka. Data was collected both in English and Bengali with a pre-tested structured questionnaire and a checklist. Results Dental caries (d) was found in 69.2% of the children while missing (m) and filled (f) teeth were recorded in 14% and 21.5% of the children respectively. Almost three quarter children (72%) demonstrated an overall dmft score 1 or higher; whereas one third children (28%) demonstrated dmft score 0 or free from any form of dental decay, missing teeth and dental filling. Increased age of the children was directly associated (p<0.05) with the number of decayed, missing or filled teeth. The study also revealed that correct method of brushing was practiced by only 44% of the children and recommended brushing time (1-3 minutes) was done by 37.3% only. Children who were assisted by their parents during brushing experienced less caries compared to the children who brushed their teeth by themselves and this finding was statistically significant (p<0.05). Taking snacks between meals was preferred by 106 children and among them 97.2% did not clean their mouth after having snacks.

Background: Oral squamous cell carcinoma which occurs closely to the mandible has a tendency to invade mandible. An accurate preoperative evaluation of mandibular invasion is important for optimum treatment planning. Aim of this study is to determine the accuracy of CBCT in detection of mandibular invasion in oral squamous cell carcinoma. Study design: In this prospective observational study 35 patients of histologically proven squamous cell carcinoma which was close proximity to the mandible were selected. The results of preoperative CBCT scan of mandible were compared with that of post operative histopathology of bone and thus sensitivity, specificity, negative predictive value, positive predictive value were calculated. Results: Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of CBCT were 96%, 90.90%, 96%, 90.90%, 97.14% respectively (Chi squared with Yates correction equals 21.844 with 1 degrees of freedom, p value < o.oooo1). Conclusion: Cone beam computed tomography is a sensitive test and has an acceptable range of specificity. Update Dent. Coll. j: 2018; 8 (2): 18-22

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.

Abstract:Managing malocclusion by orthodontic treatment require consideration of many factor. One of the important this one is age, as it is the indicator of remaining growth and development of face and jaw and body generally. Clinicians often remain in doubt to plane the orthodontic treatment especially with adult age group. Many biological and psychosocial factors associated with adultsneed a change in biomechanics and treatment approach than that in growing adolescents.This article reports and describesorthodontic management of two adult (from both gender)with modification of conventional approach that manage those successfully. Two years post treatment follow up already ensure stable occlusions and improve quality of life. Introductions:

Background : Dimensions of teeth have been an excellent tool for determining clinically relevant aspects of dental aesthetics. Especially, the anterior teeth crown height and their mesio-distal widths are very important, because of their strategic anatomical position of being in the centre and in the front of the upper jaw. Objectives : The presented study was aimed to find the nominative data of the average anatomic crown height and mesio-distal width of maxillary central incisors of Bangladeshi population irrespective of age and sex. Methods : This observational study was carried out at Update dental college & Hospital. 110 typical extracted human maxillary central incisor teeth were collected randomly from the Oral Anatomy and Physiology Department of Update dental college and Sapporo dental college. Results : In this study it shows that maxillary central incisors’ average crown length is between  7.25 – 11.75 mm and the mean crown length is 10.37(SD±0.90) mm. The average mesio-distal width is between 9.00 – 13.00 mm and the mean mesio-distal width  is 8.51 (SD±0.62) mm. Conclusions : Apart from other specific and objective parameters related to dental aesthetics, these values of mesio-distal width and the length of the maxillary central incisors mentioned in this study will serve as guidelines for the diagnosis and treatment planning, especially in restorative dentistry, orthodontics and periodontal surgeries.DOI: http://dx.doi.org/10.3329/updcj.v2i1.13954 Update Dent.
