Epidemiological study of odontogenic tumours: An institutional experience.

Epidemiological studies on odontogenic tumours conducted in different parts of the world emphasised variation in incidence and distributional pattern. Such epidemiological studies are obscured in Southern state of Andhra Pradesh in India. Present study was conducted at an institutional setup in South Indian population to assess the demographic data of odontogenic tumours. The retrospective study, which included all the odontogenic tumours from the archives of department of oral pathology, Dental teaching and Research Institution in southern part of India. Cases were selected based on the classification of WHO 2005 histopathological typing for odontogenic tumours and the assessment year considered was from 2002 to 2014. Demographic data was analysed for these tumours. Results were analysed using Chi-Square Test. Incidence of the odontogenic tumours was found to be 2.17%. Peak age incidence was recorded highest in third and fourth decade of life. Males were commonly involved [59%] with the male to female ratio of 1.43:1. Posterior mandible [53.4%] was the chief anatomical location involved with the tumours. Considering the individual lesions, Ameloblastoma [49%] was found to be more frequent, followed by Keratinizing cystic odontogenic tumour [32%], Odontome [6.2%], Adenomatoid odontogenic tumour [5.5%], Odontogenic myxoma [2.4%], Ameloblastic fibroma [0.6%], Calcifying epithelial odontogenic tumour [1.8%] and Squamous odontogenic tumour [1.2%]. The total frequency of odontogenic tumours was 2.17%. Ameloblastoma and Keratinizing cystic odontogenic tumours were the predominant tumours, demonstrating significant regional and geographic variation.

Palatal changes of reverse smokers in a rural coastal Andhra population with review of literature.

AIM: To investigate and record the palatal changes in individuals habituated to reverse chutta smoking in rural coastal Andhra population. MATERIALS AND METHODS: Sixty individuals out of whom 47 females and 13 males habituated to reverse smoking with no other tobacco and alcohol habits and no other systemic disturbances were selected. The palatal changes were recorded by six examiners. Database were searched for the following terms "reverse smokers," "nicotina palatini" and "palatal lesions." RESULTS: The mean and percentage prevalence of the each lesion recorded and agreed by six examiners among 60 subjects showed presence of 87.77% hyperpigmented areas, 64.44% depigmented areas, 51.66% excrescences, 32.22% potentially malignant lesions and 9.72% frank ulcerations. CONCLUSION: Reverse smoking is an endemic tobacco habit still practiced in the coastal rural Andhra Pradesh. It is a well-established and socially acceptable habit among adult females. The changes recorded clinically shows characteristic features that are unique among this population group.

Unusual foreign body in the nasal cavity of an adult with repaired cleft lip and palate.

Intranasal foreign bodies arising from dental clinical practice, especially in patients with cleft lip and palate (CLP) occur rarely and are very scarce in the literature. This article reports an unusual case of a dental impression material presenting as a foreign body in the nasal cavity of an adult with repaired CLP who presented for dental prosthetic rehabilitation. To our knowledge, this is only the second report presenting nasal foreign body in a cleft patient arising due to a dental impression procedure.
