Oral health status of Italian children with Autism Spectrum Disorder.

Abstract

Autism Spectrum Disorder (ASD) is characterised by communication deficits and repetitive unusual behaviours. The behaviour guidance of these children represents a challenge for the dental team. The aim of the study was to evaluate the oral health status in a group of Italian children with ASD. Study Design: Sixty-four Italian children with ASD and 64 controls were included. Data were collected by means of questionnaires and clinical examinations. Dental trauma (p=0.007), bruxism (p=0.001) and biting objects habit (p=0.021) were more frequent in the study group; fluoride exposure was lower (p=0.001) (chi-square test). The mean plaque index was 1.48 ±0.75 in the study group and 0.81±0.56 in the control group (p=0.001; Mann-Whitney U test); the mean dmft/DMFT was 3.00 ±1.2 and 2.3 ±1.8 in the study group and 1.8 ±1.1 and 1.0 ±1.1 in the control group (p<0.001; Mann-Whitney U test). Anterior open bite was more frequent in the study group (p=0.013; Chi-square test). No significant differences were found for enamel defects, molar relationship, posterior crossbite and deep bite. Significantly more children with ASD showed a negative behaviour (80% vs 35%: p =0.001; Chi-square test). CONCLUSION Children with ASD have a poorer oral health status than healthy children. The early establishment of a home dental hygiene should be encouraged.
