Dentigerous cysts are the developmental cyst of odontogenic origin caused by the accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth usually in the second and third decade of life. It surrounds the crown of the unerupted or impacted tooth. It has a prevalence of 22.6% overall and 4-9% among children up to 10 years whereas radicular cyst shows a prevalence of 54.7%. In this article, a case of rare occurrence of dentigerous cyst in a 10-year-old child and its treatment are presented. The dentigerous cyst was fully enucleated and the deciduous second molar and permanent second premolar tooth was removed from the mandibular right premolar region.

An immediate complete denture is a replacement of the lost natural teeth and associated tissues which is inserted into the patients mouth immediately following the extraction of remaining teeth. The transition from dentulism to edentulism should be psychologically atraumatic as far as possible. The case presented here are interim (transitional or non transitional) immediate complete denture was planned after extraction of remaining natural teeth.

For the unsuspecting clinician, a common cause for non-surgical endodontic treatment failure in mandibular premolars is missed roots or canals, as the root canal morphologies of these teeth can sometimes be aberrant. Even in the absence of state-of-the art, three-dimensional imaging techniques, it is prudent clinical approach to have detailed pre-endodontic periapical radiographic assessment of these teeth. Evaluation of sudden changes in the density (fast break) of the root canal space, periodontal ligament contours, root bifurcation, if any, are important points to note, pre-operatively. Bifurcation of mandibular second premolar roots in the mesio-distal axis is very rare and even rarer when it occurs bilaterally. Radiographic exposure of asymptomatic contralateral teeth may also be necessary, to help uncover latent pathologies and evaluate the bilateral presence of anomalies, if any, to justify simple, early restorative intervention to obviate the need for later, more complex root canal treatment.

Background: The existing literatures comprehend the prevalence of various myths related to dentistry amongst general public in different parts of India. Continuous efforts are being made by Public health dentists and other healthcare workers, to spread awareness and promote good oral health care across the nation. This study was done to assess the prevalence of myths related to dentistry among people of Lucknow. Material & Method: The study was carried out amongst the patients visiting the dental outpatient department of King George’s medical University. 250 subjects were questioned about myths related to oral hygiene, teething and childhood, tobacco use, dental problems and dental treatment. Results: The results of all 23 questions were obtained in 3 sections ie ‘Yes’, ‘No’ and ‘Don’t Know’ and percentage calculation was done for each question. In this study the maximum participants belonged to Upper lower class according to Kuppuswamy socioeconomic scale. The myths which were still prevalent in the population under study, were, cleaning teeth with a twig is better than toothbrush, falling of teeth with aging is a natural process and an ulcer which do not heal for a longer duration always lead to cancer. Conclusion: The results of this study concluded that there is increase in knowledge amongst the public of Lucknow city. The percentage of people who did not believe in the various myths questioned in this study was more than the people who still believed in it or were unaware of any such myths. Thus, we can say that the efforts been put up by various healthcare workers to create awareness are effective in eradicating the false traditional believes of Indian citizens but still there is a need to put in more hard work to demolish it completely and attain good oral health for all.

Background: Tooth surface loss (TSL) is the loss of dental hard tissue including enamel and dentin caused by factors other than dental caries. This condition can be seen clinically as attrition, erosion, abrasion and abfraction. TSL can cause dental hypersensitivity and loss of vertical dimension. Also, TSL can be asymptomatic in which patients are not aware of the condition. Aims: This review will provide an overview of the definitions, prevalence, aetiology, diagnosis and preventive management of TSL. Conclusion: TSL or tooth wear (TW) is a common physiological condition occurs throughout the patients’ life, however, excessive tooth wear that cause functional and aesthetic problems are considered pathological wear. Dentists should be aware of the aetiology of the tooth wear in order to provide a successful diagnosis, management, and treatment. Clinical significance: it is of paramount importance to know and differentiate between the causes of the TW to be able to prevent and treat the problem. In mild to moderate TW without functional and aesthetical concerns, preventive measurements and regular follow-up will help to monitor and prevent further destructions.
