Oral Manifestations of Eating Disorders

Eating disorders are potentially life-threatening disorders. In this article, we discuss the oral manifestations of eating disorders so as to enable dental practitioners to recognize the effects of eating disorders and to manage the patients with eating disorders

Rubinstein Taybi syndrome: Broad thumbs - Hallux syndrome

The Rubinstein Taybi syndrome is a rare genetic disorder that is characterized by varying degrees of intellectual disabilities, distinct facial features, broad thumbs and first toe, and delay in cognitive and motor skill development. This is often detected in newborns because of the physical features that are apparent at birth. Correct diagnosis helps in the appropriate genetic counseling of parents. Here we report a case wherein the characteristic physical features led to the diagnosis of the Rubinstein Taybi Syndrome

Evaluation of the remineralization potential of amorphous calcium phosphate and fluoride containing pit and fissure sealants using scanning electron microscopy

Aim: To evaluate the remineralization potential of Amorphous Calcium Phosphate (ACP) and Fluoride containing pit and Fissure Sealants using Scanning Electron Microscopy. Materials and Methods: Thirty maxillary first premolars were divided into three groups of ten each and were randomly selected for ACP containing (Aegis- Opaque White, Bosworth Co. Ltd.), Fluoride containing (Teethmate F1 Natural Clear, Kuraray Co. Ltd.), resin based (Concise- Opaque White, 3M ESPE Co. Ltd.) pit and fissure sealant applications. The Concise group served as a control. The teeth weresubjected to the pH-cycling regimen for a period of two weeks. After two weeks, the teeth were sectioned bucco-lingually into 4mm sections and were observed under Scanning Electron Microscope at 50X, 250X, 500X, 1000X and 1500X magnifications. The qualitative changes at the tooth surface and sealant interface were examined and presence of white zone at the interface was considered positive for remineralization. Results: Both ACP containing (Aegis) and Fluoride containing (Teethmate F1) group showed white zone at the tooth surface-sealant interface. The resin based group (Concise) showed regular interface between the sealant and the tooth structure, but no clear cut white zone was observed. Conclusion: Both, Aegis and Teethmate F1 have the potential to remineralize. Release of Amorphous Calcium Phosphate molecules in Aegis group and formation of Fluoroapetite in Teethmate F1 group, were probably responsible for the remineralization

Digital Subtraction Radiography - A Technique Revisited

Digital imaging has changed the scenario of medical and dental imaging as it has been able to address many limitations associated with traditional film based radiograph. However, subtle changes on the image are still difficult to appreciate by the human eye because the changes are buried in a background of normal anatomic structures, and are not clearly evident. Digital subtraction radiography is one of the image enhancing technique which addresses this problem and has found its use in various fields of dentistry in the recent past. However, there is lack of review in the literature regarding this widely used technique. The purpose of this article is to present an overview of this technique and its uses in various fields of dentistry

Dental age estimation by Demirjian′s and Nolla′s method: A comparative study among children attending a dental college in Lucknow (UP)

Introduction: Estimation of age is an important aspect of forensic science. The assessment of age is useful in forensic odontology and in treatments plans of orthodontic and pedodontic patients. Aims and Objectives: The aim of the study was to determine dental age from orthopantomograph using Demirjian′s method and Nolla′s method. It was also to evaluate the interrelationship between chronological and dental age according to both these methods and to evaluate which technique was better. Materials and Methods: The study was conducted in the Department of Oral Medicine and Radiology of Babu Banarasi Das College of Dental Sciences (UP, Northern India). A total of 300 subjects (150 girls and 150 boys) of age group from 6 years to 15 years were enrolled. These subjects were grouped by a difference of 1 year into 10 groups (each group comprised of 30 subjects: 15 males and 15 females). For every individual included in the study a panoramic radiograph was taken, with standard parameters and adequate protective measures. Results: The results imply that Demirjian′s method is applicable to all age groups and for both genders with better accuracy than Nolla′s method, which had a limited utility in younger age group. Thus Demirjian′s method is a better method when compared to Nolla′s method in Northern Indian population
