Dentists' knowledge and attitudes regarding PFPT: A single study in East Java, Indonesia

Abstract

ObjectivePigmented fungiform papillae of the tongue (PFPT) are infrequently encountered and inadequately documented pigmented lesions that pose challenges in diagnosis and subsequent treatment planning. The study was aimed at analyzing dentists' knowledge and attitudes regarding PFPT morphologies, to determine diagnosis and subsequent treatment planning. MethodsA cross-sectional study was conducted among dentists in East Java through an online questionnaire. Four clinical photographs of PFPT were presented, accompanied by seven questions assessing dentists' knowledge of PFPT, including lesion types, tongue structure involvement, Holzwanger classification, lesion patterns, suspected diagnoses and the nature of the lesion (benign or malignant). Additional questions to evaluate attitudes included prior experience with PFPT in practice, potential malignant transformation, diagnostic investigation and required treatment. Knowledge-associated attitude differences were statistically analyzed with the Mann–Whitney test with a threshold of p < 0.05. ResultA total of 117 dentists participated, most of whom were women (69.23%) and were 26–30 years of age (44.44%). Dentists 41–50 years of age had superior knowledge to those 20–30 years of age (p = 0.005). Practitioners with 1–5 years of experience showed significant differences in knowledge regarding PFPT (p < 0.05). No significant differences in knowledge level and attitudes were observed, particularly regarding PFPT treatment and supporting investigation (p > 0.05). However, prior encounters with PFPT cases were significantly associated with treatment decisions and supporting investigations for diagnosis (p < 0.05). ConclusionMost participating dentists had substantial knowledge of PFPT cases. Dentists' understanding, as reflected in their attitudes toward investigating and treating PFPT, was notably influenced by prior encounters with PFPT cases.
