ABSTRACT
Introduction: Oral mucosal health is part of general health that also requires attention. Research on
oral mucosal in children has not widely conducted, especially in the Jatinangor sub-district as one of the
educational centres in West Java. This study was aimed to determine the most common and predicted the
diagnosis or conditions of oral mucosal lesions among elementary school children. Methods: This research
was a cross-sectional study. The purposive sampling method was used, in which only the fifth-grade
students from the elementary school cluster near the centre of the Jatinangor sub-district were involved.
The inclusion criteria were healthy condition, cooperative, able to communicate with the examiner, and
obtained permission from the parent/guardian. The oral mucosal lesions were examined using disposable
dental tools and a white light headlamp. Oral mucosal lesions found on examination defined as oral
diseases and normal variation of oral mucosal. Results: A total of 226 students, consisting of 115 males
and 111 females, were included in this study. The oral mucosal lesions found were described as follows:
100 cases of pseudomembranous plaque, 106 cases of macula, 56 cases of ulceration, 45 cases of cheek
biting, and another fewer lesions. The lesions' diagnosis was coated tongue for the pseudomembranous
plaque, physiologic pigmentation for the macula, aphthous stomatitis/traumatic ulcer/angular cheilitis
for ulcers, linea alba for cheek biting, and others. Conclusion: The most commonly found oral mucosal
lesions were macula which is diagnosed as macular hyperpigmentation, followed by pseudomembranous
plaque which is diagnosed as coated tongue
