LS Wong, JD Seow, SK Lim, YL Chieng: The Prevalence and Distribution of (Biopsied) Oral Lesions in an Oral Surgery Unit in East Malaysia: A Cross-sectional Retrospective Study. Mal. J. Oral Maxillofac. Surg. 2011; 9: 14–16.

Abstract: The prevalence of an oral lesion varies by geographic regions. The Dental Specialist Clinic, Hospital Sibu in Malaysia is one of the main referral centers in Sarawak. The aim of this study is to evaluate the prevalence and distribution of common referred oral lesions to Dental Specialist Clinic, Sibu Hospital from year 2006 until 2011. A total of 187 histopathological records of oral tissue biopsied that fulfil the inclusion and exclusion criteria were reviewed and analysed. Oral and maxillofacial diseases were seen more in female (female to male ratio was 1.5:1), young adults (28%) and among Ibans (43%). Majority of biopsy specimens were of soft tissue origin (70%). The most common biopsied lesions were inflammatory lesions (25.1%). Tumours formed 32.6% of the entire sample with malignant tumour constitute of 12.8%. Other common histopathological diagnoses comprised intrabony and soft tissue cysts, odontogenic tumour, benign tumour, benign fibroosseous lesions, and premalignant lesions. Future population study is required to clarify the epidemiology of oral lesions in Malaysia.
