To check the reliability of panoramic radiographs in assessing mesiodistal angulations while considering the true long axes of teeth in relation to a horizontal reference archwire. A clear anatomical typodont with removable teeth was used with 0.8-mm chromium steel balls glued over the incisal/occlusal and apical/furcal portions of teeth to serve as reference markers for representing true long axes of teeth on radiographs and photographs. A photograph of each tooth was taken with a particular technique to serve as a medium through which to measure true mesiodistal angulations of teeth. Only overall maxillary teeth angulations significantly correlated to true mesiodistal angulations. Radiographic relationship of the long axes of adjacent teeth (convergence or divergence) in the mandibular as well as the maxillary arch did not show any significant correlation to true degree of convergence or divergence and displayed a tendency to accentuate the maxillary canine to premolar divergence and mandibular lateral incisor to canine convergence. Panoramic radiographs provide a poor representation of the mesiodistal angulations of teeth and require cautious use with clinical judgment and adjunctive procedures to ascertain root angulations.

Periodontitis is a chronic inflammatory disorder characterized a complex interaction between periodontopathic bacteria and the host inflammatory response resulting in release of pro-inflammatory cytokines leading to the destruction of periodontal tissues and alveolar bone. One of the important host factors involved in periodontal diseases is matrix metalloproteinases (MMPs), which is responsible for collagen and extracellular matrix (ECM) degradation of the periodontal tissues. MMPs comprise a family of around 25 members broadly categorized into six groups, which are involved in various physiological and pathological conditions. The activities of MMP are generally balanced by endogenous inhibitors such as tissue inhibitors of metalloproteinase (TIMP), and any imbalance between MMP and TIMP levels plays an important role in the disease progression. Assessment of MMP in tissues, GCF, and saliva may serve as an important biomarker in diagnosis of periodontal diseases and also for prognostic follow-up. Targeted therapy aimed at reducing effects of MMP may serve as a useful adjunct for treatment of periodontitis. This review provides an overview of MMP and its role in various physiological and pathological conditions with emphasis on its association with periodontal diseases. A note on its inhibitors and therapeutic importance is also provided. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd 206 September 2014. Source

Women in Indian culture have a paradoxical status: on the one hand, goddesses are worshipped for power and prosperity; on the other hand, working women face challenges due to age-old beliefs and sociocultural norms. With 60% of the students enrolled in undergraduate dental education currently being women, there is a need to study the challenges these women are facing and how they tackle them. The aim of this survey study was to assess the barriers women dentists face in career advancement and how successfully they balance the personal, professional, and social aspects of their lives. Questionnaires, consisting of four qualitative and 24 quantitative items, were distributed to 500 women dentists: postgraduate residents and faculty members in dental colleges of Mumbai and Navi Mumbai, as well as private dental practitioners. Of the 500 women, 210 returned the survey, for an overall response rate of 42%. The results showed that 95% of the respondents believed they successfully balance the various spheres of their lives, but the most common challenges they faced continued to be traditional gender bias, dual professional and home responsibilities, and preconceived ideas about women.

Purpose: To evaluate the changes in mutans streptococci counts in saliva after short term probiotic intervention and its delayed effects on salivary mutans streptococci count. Methods: 40 children in the age group of 12-15 years with medium to high caries activity were randomly divided into Group I Control (plain milk group) and Group II Experimental (probiotic supplemented milk group). Duration of the study was 9 weeks; which was evenly divided into three phases: baseline, intervention and post-treatment period; each phase consisting of three weeks. After baseline period of 3 weeks, children in group I were given plain milk and in group II milk containing probiotic Lactobacillus rhamnosus hct 70 for 3 weeks; followed by a 3 weeks follow up period. After every phase saliva samples were collected to estimate salivary mutans streptococci counts. Results: The difference in the post follow up mutans streptococci count of group I and group II, was highly significant with p value < 0.001. In the control group, the difference in the mean salivary baseline, post treatment and post follow up mutans streptococci counts was not statistically significant (p = 0.001). In the experimental probiotic group, the difference in mean salivary baseline, post treatment and post follow up mutans streptococci counts was statistically highly significant ( p = 0.000, p ≠0.001). Conclusions: Statistically significant reduction in salivary mutans streptococci counts immediately after consumption of probiotic Lactobacillus rhamnosus hct 70 containing milk suggest a beneficial effect of probiotic Lactobacillus rhamnosus hct 70 in the prevention of dental caries.

Teratomas of the tongue are rare, and often accompany other anomalies within the head and neck. We describe a combination of anomalies in a 6-week-old infant with teratoma and bifid tip of the tongue, severe tongue tie, and polydactyly. The teratoma was excised and the tongue tie released with no complications. © 2010 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved. Source
