Background: Lichen planus is a chronic mucocutaneous disease with primary or secondary involve- ment of the oral mucosa. In particular in case of erosive lichen planus most of the patients experience no long term symptoms relief of conventional topical treatment such as corticosteroid ointment. Topical tacrolimus applications to mucosal lesions seem to be an alternative treatment approach.Objective: The aim of this study was to compare the efficacy of topical tacrolimus ointment with that of triamcinolone acetonide ointment on patients suffering from oral lichen planus.Study design: This was a clinical trial.  Study setting and period: This study was conducted in outpatient department of Oral and Maxillofacial Surgery, Dhaka Dental College in the period between June 2013 to May 2014.Subjects: A total of sixty patients were enrolled. Out of sixty patients thirty patients used topical tacroli- mus 0.03% (Group A) and another thirty patients used topical triamcinolone acetonide( Group B) for the treatment of oral lichen planus.Methods: A total of sixty patients were asked to answer a questionnaire regarding the degree of pain and burning sensation in every two weeks according to visual analogue scale (VAS). In every two weeks change of colour and size and also any side effects of these drugs were assessed. Data were analyzed using Statistical Package for Social Science (SPSS), version 15.0 for windows.Results: At the end of 12th week follow up periods complete relief of pain and burning sensation in group A patients were 100% and in group B it was 30%. There was no side effect in two study group patients.Update Dent. Coll. j: 2018; 8 (1): 17-21

Background: Oral hygiene maintenance becomes difficult during fixed orthodontic treatment.Objective: The aim of this study was to assess Gingival Bleeding Index among patients treated with fixed orthodontic appliances in a tertiary level hospital.Metanitil and Methody: This study was conducted on 100 patients treated with fixed orthodontic appliances for more than six months in the OPD of Orthodontics Department at Bangabandhu Sheikh Mujib Medical University, Dhaka from July 2013 to July 2014. All the information related to oral hygiene maintenance like brushing, dental floss use, use of mout hwash during treatment in the OPD were recorded. The Gingival Bleeding Index (GBI) was calculated and recorded. Apart from this, frequency of brushing, type of tooth brush, technique of brushing and inter dental brush were also considered.Result: Over all mean value of GBI was 23.44±17.00. Mean value of GBI was 26.44 ± 15.23 among patients who brushed their teeth once a day but it was decreased gradually as the patients increased frequency of toot hbrush use per day and became 11.55±4.71 among the patients who brushed their teeth thrice a day. Mean value of GBI was 23.46±17.18 who did not use dental floss and 22.85 (12.64) who used dental floss once a day. Mean value of GBI was 25.30±17.73 who used inter dental brush irregularly but 2.75±0.35 who used it thrice a day. Mean value of GBI was25.17±17.69 who did not use mouth wash whereas it reduced to 8.00±0.00 among them who used mouth wash thrice a day.Conclusion: The Gingival Bleeding Index (GBI) is increased in patients treated with fixed orthodontic appliances.KYAMC Journal Vol. 9, No.-3, October 2018, Page 129-132

Background: Third molar is the most commonly impacted tooth in the oral cavity and accounts for large of all impactions. The most common complication in the extraction of the third mandibular molars is nerve and vessels damage. Therefore, thorough radiographic assessment is a necessary to avoid these surgical complications. Objective: The purpose of this study was to evaluate the frequency, angulation, depth of the impacted mandibular third molars and its relationship with ramus on radiographs. Materials and Methods: This study comprised 800 orthopantomograms (OPGs) of patients attending different dental clinics and hospitals in Rangpur region, Bangladesh between June 2014 to May 2015. Panoromic Radiographic assessment was carried out to evaluate the pattern of third molar impaction in terms of age, gender, angulation of impaction, level of eruption and available retromolar space using panoramic radiographs and Pell & Gregory classification. Results: A total of 314 radiographic third molar areas were found in this study, out of them 137 belong to male patients and 177 belong to the female patients. The mesio angular types of angulation was most prevalent (46%) whereas distoangular was rare (5%) in our study. In relation to anterior border of the ramus of mandible Level B 52% and Class II 59% were the most common pattern of impaction. The female tends to be dominant as compared to male & the maximum number (35%) of impacted third molars are found in an age group of 38 years and above. Conclusion: Panoramic radiographs can be used as reliable investigation for evaluation of impacted mandibular third molar. KYAMC Journal.2021;12(01): 08-13

Background: Malocclusion is still not considered as a dental problem because of more emphasis is given to the treatment of dental caries and periodontal diseases due to pain complained by patients. Objective: The study was conducted to find out the pattern of diseases of orthodontic patients visiting in a regional tertiary care hospital in northern area of Bangladesh. Materials and Methods: This snap-shot study was conducted on randomly selected 84 patients attended in the Department of Orthodontics & Dentofacial Orthopaedics, Dental unit Thengamara Mohila Sabuj Sangha (TMSS) Medical College and Hospital, Bogura from July 2016 to June 2017. All data were collected from patients’ history and clinical examination of the patients. Descriptive statistics were calculated using MS Excel from the collected data. Results: One third of the patients (33.33%) have normal over bite. Class I and Class II molar relationship are distributed as 44% and 53.5% respectively. Class I and Class II division 1 Incisor relationship is distributed as near about same, 44% and 34.52% respectively; and 14.29% have Class II division 2. Class I and Class II Canine relationship are distributed as near about same, 44% and 48.80% respectively. Forty four percent patients have normal over jet, 34.52% patients have increased over jet, and 7.20% patients have reversed over jet. Conclusion: The epidemiological data on the prevalence of malocclusion is an important determinant in planning appropriate levels of orthodontic services in the Bangladeshi population and further studies are required to provide accurate estimates of the orthodontic treatment.
