Introduction: Oral mucosal lesion (OML) is any abnormal alteration of mucosa in colour,
texture, surface, and swelling. OML have many etiological factors such as infections,
local trauma, systemic disease and carcinogens. Objective: To evaluate the prevalence
and clinicodemographic features of OML among patients attending the Oral Medicine
(OM) Clinic at Hospital Kuala Lumpur (HKL). Materials and methods: Clinical records of
patients diagnosed with OML and follow-up at OM Clinic of HKL from 2009 until 2019
were reviewed retrospectively. Relevant clinicodemographic data were extracted,
evaluated and analysed using SPSS version 21. Results: A total of 490 patients were
included in the present study. The prevalence of OML was highest among 50-59 years
old (21.8%), followed by 60-69 years old (20.2%) in which female (61.2%) were mostly
affected and 42.8% were of Malay origin followed by Indian (27.6%) and Chinese ethnic
(23.1% ). The most common lesion was oral candidiasis (26%) followed by oral lichen
planus or oral lichenoid reactions (24.8%), aphthous ulcer (15.5%) and vesiculobullous
lesion (14.8%). An important finding was the reported premalignant lesions with
leukoplakia (5.5%) and oral submucous fibrosis (1.3%). The most common site for OML
was buccal or labial mucosa (39.2%) followed by tongue (32.7 %). Discussion: This study
showed that the OML is highly prevalent in age range of 50-59 years and 60-69 years
comparable to local study done by Zain et al. Female and Malay subjects with OML were
dominant, this was in accordance with Taiyeb et al. The main site of OML involvement
was buccal or labial mucosa, a finding consistent with other studies (Ramandeep et al,
Garciapola et al). A variety of lesions were encountered in this study with predominance
of oral candidiasis, a finding similar to previous studies (Sabah et al, Vallejo et al).
Conclusion: The finding of this study is only a baseline involving a small number of
subjects. Extensive data involving multi-centre need to be established.
