Use of a Picture Exchange Communication System for preventive procedures in individuals with autism spectrum disorder: pilot study.

The aim of the present study was to evaluate the use of the Picture Exchange Communication System (PECS) in individuals with autism spectrum disorder (ASD) in order to facilitate patient-professional communication during preventive procedures. In this study, 26 patients with ASD, between 5 and 19 years of age (10±3.3 y), were divided into two groups: G1 (n = 13) with no previous experience of dental treatment, and G2 (n = 13), with such previous experience. The initial approach followed the principles of the Son-Rise Program®. The seven PECSs presented the routine of the dental office: "room," "ground," "chair," "dentist," "mouth," "low," and "triple." Each PEC was used up to three times in order to acquire the skill proposed. It was verified that G2 required a greater number of times to achieve the acceptance of PECS "ground," "dentist," "mouth," and "triple" (p < .05). We concluded that PECS facilitated patient-professional communication during preventive procedures, including for ASD patients with previous dental experience.

Oral conditions in children with cerebral palsy.

PURPOSE: Cerebral palsy (CP) is a major severe childhood disability and its prevalence is increasing, particularly among premature low-weight newborns. The oral conditions observed demonstrate the need for home and professional care for these individuals. This study aimed to investigate dental caries, plaque index, time of eruption, malocclusion, bruxism and motor oral skills in a group of 62 CP children (study group). METHODS: The results were compared to those obtained for a control group with 67 normal children. Nonparametric statistical tests including the Mann-Whitney test, Fisher's Exact test (P), Chi-square test (chi2), and Cochran's Q test were used according to the nature of the variables studied, with the level of significance set at P<.05. RESULTS: The results showed a significantly higher DMFS index for CP children with permanent dentition of both sexes when compared to normal children. A significantly higher plaque index was also observed in the study group. A high tendency to delayed eruption of permanent molars and significantly higher percentages of malocclusion and bruxism were observed in the study group with permanent dentition. Residual food and mouth breathing have been frequently found in CP children. CONCLUSIONS: Earlier preventive measures for CP patients are required because they are a high-risk group for dental caries.
