Background: Oral Lichen Planus (OLP) is one of the most common dermatological disease which is present in the oral cavity. It is a chronic autoimmune, mucocutaneous disease that affects oral mucosa as well as the skin, genital mucosa and other sites of the body.Method: In this review study, various databases such as Google Scholar, PubMed Central, Hinari and Cochrane library were searched for articles with keywords lichen planus, oral lichen planus, premalignant lesions, management of Lichen planus. Articles were searched from January 2015 to 5th November 2020.Result: From the 34 articles obtained after reviewing the abstracts, most relevant 32articles were evaluated in this study.Conclusion: The etiology, pathophysiology, clinical presentation, histopathological features, diagnosis and various management for oral lichen planus is discussed. This article also compares the existing and the most recent treatment modalities that are available throughout the world that are discussed in the literatures. However, more intensive studies must be carried out to find the best treatments which are cost-effective in the long run. Update Dent. Coll. j: 2020; 10 (2): 29-34

Objective: The aim of the study was to investigate the prevalence of periodontal diseases with regards to the age and sex in population around a dental hospital, and to compare the results with national and international studies.Methodology: A cross sectional study was initiated to characterize the demographic, oral health behavior. Prevalence of different types of periodontal diseases was evaluated in the out patients periodontology department of Update Dental College and Hospital Dhaka, Bangladesh. Investigation was determined by taking the history and with oral examination, using examination instruments, CPITN probe and with the help of radiographs.Result: Out of 2130 patients during year 2014-2015, 1807 were diagnosed, as suffering from Chronic plaque induced gingivitis and 323 were diagnosed, as suffering from chronic plaque induced periodontitis. Prevalence was revealed more cases of gingivitis then periodontitis and males are suffering with periodontal diseases more than the females. 21-40 years of age group patient has been suffering with gingivitis more but 41-60 years of aged patients are has been suffering with periodontitis. So commonly gingivitis occur in early ages population and they are more concern about the treatment also.Conclusion: Gingivitis is prevalent on periodontitis and male are suffering more with periodontal diseases.Update Dent.

The calcified root canals cause many problems during endodontic treatment due to difficulty in canal orifice location, negotiation, preparation as well as consideration of operating time. Most serious problem may arise during any phase of root canal treatment procedure even taking a lot of precaution. Partial or total obliteration of pulpal chamber or root canal space is the most common consequences of a tooth which is exposed to traumatic injury. The most common presentation of such a tooth is complete or partial loss of the pulp space radiographically and discoloration particularly yellow discoloration of the clinical crown. Around 7–27% of teeth having the feature of partial canal calcification shows features of pulp necrosis accompanied by radiographic signs of chronic periapical periodontitis. Very low numbers of teeth( 2-3%) may present with total obliteration of pulp chamber and the root canal system . Teeth with such features is challenging to provide a successful root canal treatment; . In this case report a 21 years old female patient attended with complaints of discoloration , mild spontaneous pain , and several episodes of gingival swelling with history of trauma four years back in her both maxillary central incisors. The case was evaluated clinico radiographically and the diagnosis was a case of calcification both maxillary central incisors. Root canal treatment to manage the calcified canals following conventional technique was planned . After treatment patient was free from subjective and objective signs and symptoms and she was advised for periodic follow-up Update Dent. Coll. j: 2020; 10 (2): 21-25

Periodontal diseases are the most commonly occurred diseases in the oral cavity with a widespread distribution around the globe. Variation in periodontal tissues associated with the aging and gender of the patient. The aim of this study was to determine relationship of age with periodontal diseases for males and females in Bangladeshi people. This study was conducted on 1837 patients visiting Department of Periodontology & Oral Medicine, Update Dental College & Hospital, from January 2017 to December 2018 (2 years) through a non-interventional cross-sectional method using descriptive and analytical statistics. Periodontal disease is the dependent variable of this study; patient age and gender serve as the independent variable. Total 37.5 % patients suffered from periodontitis and 62.5% suffered from gingivitis. Up to 48 years of age the prevalence of gingivitis was higher (70.64%) but periodontitis was more common (64.76%) in case of people over 48 years age. There is a significant (p<0.05) correlation between age and periodontal diseases exists in this study but no significant (p>0.05) correlation identified with gender. Distribution of periodontal diseases shows similar pattern between female (gingivitis=62.61%, periodontitis=37.53%) and male (gingivitis=62.47%, periodontitis=37.39%).Periodontal diseases are primarily correlating with the age but gender may not be associated. The most prevalent form of periodontal disease is gingivitis. Update Dent. Coll. j: 2019; 9 (2): 13-16
