To describe the relationship and impact of age group, gender and skin complexion on the prevalence and clinical distribution of oral mucosal alterations of developmental origin (OMA-DO) among school children aged 5–13 years.Methods
A randomized representative national survey of Jordanian school children including all Country geographic areas was performed. Cut-off age that significantly correlated with presence and distribution of OMA-DO was identified (ROC curve). Skin complexion was classified into light/fair, intermediate/tan, dark/brown based on skin complexion index. Chi square test with P value ≤ 0.05 was used for significance of correlations.Results
Two thousand two hundred and fifty one children were clinically examined. The average age that significantly correlated with prevalence and distribution of OMA-DO was 9.9 years. Female gender was significantly correlated with four OMA-DO: leukoedema (L), linea Alba (LA), Fordyce's granules (FG), commissural lip pits (CLP) and wider distribution of racial pigmentations (RP) (P < 0.05, χ2 test). Older age group (9.9–13 years) was significantly correlated with 7 OMA-DO: L, LA, FG, frenal tag, CLP, mandibular and maxillary tori (MT) as well as wider clinical distribution of RP, FG, L (P < 0.05 χ2 test). Dark skin complexion significantly correlated with 5 OMA-DO: L, LA, FG, RP, MT and wider clinical distribution of RP (P < 0.02, χ2 test).Conclusions
Increased prevalence and wider clinical distribution of OMA-DO are significantly associated with older age group of 9.9–13 years, female gender, and dark skin complexion. Oral health care provides are encouraged to be familiar with these correlations. This knowledge is expected to improve OMA-DO diagnosis and clinical management. Continuous education programs in this field are recommended.
