Prevalence and Distribution of Oral Mucosal Lesions and Normal Variants among Nepalese Population.

Background: Oral mucosa is encountered by various lesions and normal variants. Some are not to be worried about, whereas others may be of significance. Knowing the prevalence of oral mucosal lesions in a particular region helps better evaluate, diagnose, and, thus, manage these lesions. Objectives: To assess the prevalence and distribution of oral mucosal lesions and normal variants among various age groups, genders, and sites of the orofacial region. Methods: This cross-sectional study was conducted in the Department of Oral Medicine and Radiology, KIST Medical College and Teaching Hospital from January 2021 to March 2021. Three different proformas were designed according to age, gender, and location of lesions for entry as per the WHO's guide. The obtained data were entered into a Microsoft Excel sheet for frequency analysis by SPSS, and the results were tabulated. Results: Among the records of 16572 (9703 (58.55%) males and 6869 (41.44%) females) OPD patients, 3495 (21.08%) (1934 (55.33%) males and 1561 (44.66%) females) had OMLs and 2314 (13.96%) (1626 (70.26%) males and 688 (29.73%) females) had normal mucosal variants. The most commonly seen OML categories were tobacco-associated lesions, i.e., 2056 (34.07%), tongue lesions, i.e., 1598 (26.48%), oral potentially malignant disorders, i.e., 815 (13.50%), ulcers i.e., 728 (12.06%), and infectious lesions, i.e., 256 (4.24%). Conclusion: The Nepalese population has a wide range of oral mucosal lesions and normal variants, and this study has attempted to have baseline data for the same. The most common OML was smoker's melanosis.

Steroid-induced inflammatory papillary hyperplasia?-A new entity in a non-denture wearing patient.

Key Clinical Message: Inflammatory papillary hyperplasia can be seen in a non-denture-wearing patient also therfore other etiologies need to be explored as well. Abstract: Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa, usually found in denture wearers. This case history report describes an example of the dentate patients with no history of wearing maxillary prostheses and highlights the importance of professional awareness to diagnose IPH among non-denture-wearing patients.

White sponge nevus of the oral cavity: Affecting members of two generations in a family.

The typical feature is the autosomal dominant heritance and clinically dormant, non-scarpalble, white diffuse, soft, thickened white plaques with a corrugated surface affecting mostly the buccal mucosa bilaterally which can substantially lead to the diagnosis of white sponge nevus.
