Case Report Dysgenetic Polycystic Disease of Minor Salivary Gland: A Rare Case Report and Review of the Literature
Polycystic (dysgenetic) disease of the salivary glands is a rare entity that has only recently been described in the literature. The disease is more commonly seen in females and majority of the cases have presented as bilateral parotid gland swellings. This case presenting in a 21-year-old male is the first of this unusual entity involving solely the minor salivary gland on the lower lip. This case report highlights the importance for the clinician to be aware of this differential diagnosis, when treating an innocuous lesion like a mucocele
Third molar maturity index as an efficient tool for prediction of age in a sample Indian population - A retrospective study
Introduction: The age of 18 years is an important milestone for legal matters, and developmental parameters of teeth are often used for estimation of this age. The aim of this study is to assess the efficiency of third molar maturity index (I3M) in establishing age of 18 years in Dakshina Kannada population. Methods: A total of 700 orthopantomograms were retrieved from the archives of the radiology department of Manipal College of Dental Sciences, Mangalore. The length and the width of the open apex of the mandibular left third molar was assessed using Image J software and the Third molar maturity Index (I3M) was calculated and correlated with the age of the individual. Results: Receiver operating characteristic (ROC) curve analysis showed the Area under curve of 0.94 and 0.96 in females and males, respectively, for prediction of age of 18 years. The cut-off of 0.08 predicted the 18-year cut-off with 97% specificity and 90.2% negative predictive value. The percentage of the accuracy was 80.23% if the I3M was <0.08. Conclusion: The efficiency of the cut-off of 0.08 of I3M has been tested in various population including Kosovar, Peruvian, South Indian, Libyan, Montenegro, Croatian, African (Botswana), Albanian, and Serbian. Our study also shows the efficiency of the same in South Indian Dakshina Kannada population
Permanent tooth emergence patterns in Dakshina Kannada region, India: an analysis of polymorphisms
Abstract Background The emergence of permanent teeth in humans starts with the eruption of the permanent mandibular first molar at approximately 6 years of age with the rest of the dentition following a fairly predictable sequence of eruption. The estimation of the age of a child between the ages of 5 and 14 years has so far been facilitated by the adoption of published data/databases that have not always relied on the variations in the sequence of eruption between various populations and ethnicities. The review of literature showed that there are 9 different types of polymorphisms relating to the eruption of teeth. Aim and objectives The aim of the present study was to estimate the sequence of tooth eruption in children of the Dakshina Kannada region of Southern India and establish/determine the polymorphism in the eruption sequence. Methods In this cross-sectional study, 2536 school children of the ages 4–16 years were examined for the presence of the permanent teeth. This data was tabulated with their corresponding age and gender. The sequence of eruption was then derived using Probit regression model. Results The eruption sequence derived for the maxilla was M1 I1 I2 P1 C P2 M2 and M1 I1 I2 C P1 P2 M2 for the mandible. The maxillary dentition was acquired faster in the females. The mandible showed more number of polymorphisms with I1 M1 type being the most common type of polymorphism. In maxilla P2 C, eruption sequence was interchanged in majority of the studies. Conclusion The sequence of emergence of teeth is a population-based variable that shows polymorphism and can be used as an indicator of attainment of a certain age
