The Prevalence and Association of Non-metric Dental Traits With Dentoskeletal Malocclusion and ABO Blood Groups in the Maharashtrian Population.

Introduction Non-metric dental traits (NMDTs) are a fundamental data source in forensic dentistry. Nevertheless, the insufficiency of data regarding the occurrence of these traits has instigated the present research endeavor aimed at ascertaining the prevalence, sexual dimorphism, and extent of inter-trait correlations within the Maharashtrian population of India. The secondary objective was to determine the correlations between NMDTs, dentoskeletal malocclusion, and ABO blood groups. Materials and methods This prospective, observational study included 528 individuals aged 18-30 years with dentoskeletal Class I, II, and III malocclusions. NMDTs such as the presence of Cusp of Carabelli (CoC) on the upper first molars, hypocone on the upper second molars, and tri- or bicuspid lower second premolars were observed on the dental casts of all individuals. The dental relationship was assessed clinically according to Angle's system for the classification of malocclusion. The skeletal relationship was assessed using lateral cephalograms of the individuals. ABO blood groups were obtained from their medical records. The Chi-square test of independence was used to assess the associations between various variables. The correlation between each measurement was determined using Spearman's correlation test. Multivariate analysis enabled the identification of parameters that exhibited independent associations with NMDTs. A multinomial logistic regression model was constructed using NMDTs as the outcome variable. Results The mean age of males was 20.82 ± 1.71 years and 21.15 ± 1.76 years was in females. NMDTs were predominantly seen in females (n=394, 75%), with Class II dentoskeletal malocclusion (n=265, 50%) and B blood group ((n=199, 38%). All traits showed bilateral predominance. A statistically significant association was found between CoC, dentoskeletal malocclusion, hypocone, and tricuspid lower second premolars (p <0.05). All NMDTs showed a negative correlation with sex, a positive correlation between age and the presence of hypocones and CoC, a negative correlation between age and tricuspid lower second premolars, a strong positive correlation with dentoskeletal malocclusion, and a weak positive correlation with ABO blood groups. Multinomial logistic regression model analysis revealed that none of the independent variables were statistically significant predictors of the presence of CoC and tricuspid lower second premolars, while dentoskeletal malocclusion and sex were significant predictors of the presence of the hypocone trait. Conclusion NMDTs showed a female predilection with bilateral predominance. A significant association was observed between these traits and dentoskeletal malocclusions. The most commonly observed NMDT was the presence of a hypocone on the upper second molars, followed by the tricuspid lower second premolars and the CoC.

Ameloblastomatous calcifying cystic odontogenic tumour involving the mandibular anterior region: An unusual case report.

Ameloblastomatous calcifying odontogenic cyst (COC) is a very rare histopathological variant of COC, which is an odontogenic cyst of the jaw. The term "calcifying odontogenic cyst" is not covered in the World Health Organisation (WHO) Classification of Tumors 2005 and was re-named as calcifying cystic odontogenic tumour (CCOT). There are only a few reports containing details on CCOT being associated with ameloblastoma. This variant has been classified as ameloblastomatous CCOT (type 3) as per the WHO 2005 classification. In this article, we reported an exceptional case of ameloblastomatous CCOT in a 15-year-old boy involving the mandibular anterior region, which is a rare combination for age and site of the lesion, along with an impacted tooth which is again an uncommon association.

Incidence of grinspan syndrome among tribal and suburban population of Maharashtra - A cross sectional study.

BACKGROUND: Grinspan syndrome is characterised by presence of the triad: hypertension, diabetes mellitus (DM) and oral lichen planus (OLP). OLP, seen in hypertension and diabetes mellitus, is caused by drugs used to treat these diseases according to literature, however the incidence of this syndrome in India has not yet been reported anywhere. Hence the present study was conducted with the following objectives: (i) To determine the incidence of Grinspan syndrome amongst tribal and suburban study population of Maharashtra in different gender and age groups (ii) To correlate occurrence of OLP with DM type 2 and hypertension (iii) To find out the number of patients with OLP, DM type 2 and hypertension either alone or in combination. METHODS AND MATERIAL: The present study was conducted on 4681 new patients attending the routine outpatient department (O.P.D.) of the dental hospital between January 2017 and December 2018. Patients with OLP or DM (type-2) or hypertension or any combination of these diseases were included in the present study. Brief case history of each patient was recorded. Data thus collected were analysed using SPSS version 20 for Chi-square test. RESULTS: Grinspan syndrome was found in 1.62% of the study population. Syndrome was seen in 1.02% of female and 0.59% of male. Maximum patient affected by syndrome were in 35-50 years of age group. CONCLUSIONS: Incidence of Grinspan syndrome was 1.62%, mainly seen in sub-urban females of 35-50 years and OLP seen in hypertension and diabetes mellitus has different etiology and is not caused by drugs used to treat these diseases.

Odontogenic Keratocyst: A Rare Presentation in Anterior Maxilla.

The odontogenic keratocyst is an enigmatic developmental cyst that deserves special attention. It has characteristic histopathological and clinical features; but, what makes this cyst special is its aggressive behavior and high recurrence rate. Odontogenic keratocyst is a benign odontogenic cyst, commonly affecting the mandible. These lesions have posed a great difficulty for the surgeons and pathologists.  Few cases affecting the maxilla are also reported.  Literature search suggests that odontogenic keratocysts may affect maxillary posterior and canine region. The present case reports a lesion of odontogenic keratocyst occuring in the maxillary incisor region, crossing midline which was initially misdiagnosed as infected residual cyst. After careful evaluation, it was reported as an odontogenic keratocyst. Key Words: Odontogenic keratocyst, Maxilla, Incisor teeth.
