Prevalence of Oral Mucosal Lesions in a Tertiary Care Dental Hospital of Kathmandu

Abstract

Introduction: Oral mucosa can be affected by a variety of soft tissue lesions and conditions. Benign as well as malignant lesions of oral cavity are common. Squamous cell carcinoma is one of the commonest malignancies. The present retrospective study was undertaken to study the prevalence of various oral mucosal lesions in a tertiary care dental hospital of Kathmandu.
 Methods: This retrospective study was carried out in the Department of Oral and Maxillofacial Pathology at Kantipur Dental College and Teaching hospital from January 2015 to January 2017. The study included biopsy specimen from the oral cavity. The parameters included in the study were age, gender, site of the lesion and histopathological diagnosis. The data collected was statistically analyzed.
 Results: A total of 111 biopsy cases were included in the present study. Out of which, there was 16 (14.4%) cases of non neoplastic and 16 (14.4%) cases of benign pathology. The oral cavity lesions were commonly seen in age range between 6-74 years where males 59 (53.2%) were mostly affected. The most common site for oral lesion was buccal mucosa 23 (20.7%) and anterior gingiva 23 (20.7%). 15 (13.5%) cases of oral squamous cell carcinoma were seen as the predominant malignancy affecting in the vestibular region 8 (7.2%).
 Conclusions: The present study shows benign as well as the non neoplastic lesions were more prevalent in oral mucosa with the buccal mucosa and anterior gingiva as the commonest site of occurrence.

The Spectrum of Oral Pathology Specimens: A Histopathologic Analysis of 442 Specimens

“…In this study, inflammatory diseases were the most common group, slightly outnumbering benign neoplasms. A similar finding has been reported in many studies [2,[6][7][8][9], while in others benign neoplasms were more common [10][11]. Interestingly, oral lichen planus was the most common inflammatory condition in this study (18%), exceeding what was reported in Türkiye (11.9%) and Kuwait (4.6%) [6,12].…”

Evaluation of the Frequency Distribution of Oral Biopsies in Shahid Sadoughi Hospital in Yazd During 2010-2019

“…In the study of Baharvand et al 24 , the most common sites were buccal mucosa, lip mucosa, and ventral surface of the tongue. In the study of Ghanaei et al 25 , the most common lesions were in the tongue and gums, in the study of Cury et al 26 in the gums, in the study of Ali and Bajacharya et al 28 in the buccal and gingival mucosa, and in the study by Shulman et al 29 in the palate and gums. The reason for the differences between the research results can be attributed to the different societies.…”

Oral and oropharyngeal mucosal lesions: clinical-epidemiological study of patients attended at a reference center for infectious diseases

“…The prevalence of oral lesions is primarily determined through population-based studies, 14 , 15 , 16 , 17 , 18 or studies carried out in dental centers 19 , 20 , 21 or from oral pathology laboratories. 22 , 23 , 24 However, as no standardization in OOPML classification exists, with studies classifying OOPML by a lesion group (e.g., non-neoplastic lesions) 19 or by a specific disease (e.g., oral lesions in syphilis), 25 the reported OOPML frequencies are directly influenced.…”

“…Likewise, the OOPML locations in other epidemiological surveys varied according to the diseases observed. 13 , 14 , 20 , 21 , 32 It is worth noting that the anatomical division of the oral cavity/oropharynx between studies is not standardized. 6 , 9 , 13 As an example, the soft palate, considered as an oral cavity subsite by some authors, 6 , 13 , 21 was considered as oropharynx in the present study based on TNM anatomical division criteria.…”
