Oral Health-Related Quality of Life in Celiac Portuguese Children: a cross-sectional study

Purpose Celiac Disease (CD) presents a wide variety of clinical signs and symptoms, including oral manifestations. This study pretended to characterize Oral Health-Related Quality of Life (OHRQoL) and reported oral manifestations in children with CD. Methods Target-population were children with CD. An online questionnaire, applied to children's parents, collected information about OHRQoL (using the Early Childhood Oral Health Impact Scale-ECOHIS), oral health behaviours, and history of oral manifestations. Data analysis included descriptive statistics, Mann-Whitney, Kruskall-Wallis, and Spearman correlation tests (alpha = 0.05). Results The sample included 146 celiac patients, with a mean age of 10.5 years (sd = 4.1). Mean ECOHIS score was 5.2 (sd = 6.8). The most frequently reported oral manifestations were recurrent aphthous stomatitis (46.6%), dental caries (45.2%) and dental opacity (39%). About one third of the participants mentioned improvements in oral health when a gluten-free diet was introduced. Most of the reported oral manifestations had a significant association with the ECOHIS score (p < 0.05). Conclusions The OHRQoL of children was good, however oral manifestations had a negative impact on OHRQoL. The most reported oral manifestations were recurrent aphthous stomatitis, dental caries, and dental opacities. Oral health professionals must be aware about the heterogeneity of the disease, to recognize oral manifestations associated and their importance in the early diagnosis to reduce complications and to an improvement in the OHRQoL of these patients.
