Autism is characterized as a behavioral disorder. The autistic patient has some difficulties with common life routines, such as oral hygiene and also improper diet. As a consequence the refusal of physical contact, the implementation of brushing and flossing by caregivers is difficult. The present study aimed to conduct an epidemiological study of autistic patients in treatment at the Rehabilitation Center and Neurological Organization in North of Brazil, adopting the CPO-D and ceo-d. The clinical examination has been performed with the patient sitting in chairs, at the Rehabilitation Centre itself, under artificial fluorescent light intended for room lighting. From 26 patients included in the study, 76.9 % of subjects were male with a mean age of 13 years. Fifty percent had caries, and 11.5% had lesions on the gums. The mean ceo-d of children 2-8 years was 0.67. In patients 10-15 years and 20-40 years, the mean CPO-D was 0.70, and 3.00, respectively. From the study, the most significant data, seen was that half of autistic patients had carious lesions. It is vital to improve oral health conditions in these patients and by using preventive dentistry, analyze their susceptibility to oral diseases.

Aim: The objective of this study was to investigate the levels of IL-10 in the gingival crevicular fluid in HIV-1 positive patients with chronic periodontitis and to compare with HIV-1 negative patients with chronic periodontitis, also to correlate clinical periodontal parameters, viral load and count of CD4+ and CD8+ lymphocytes (LTCD4+ and LTCD8+). Methods: 33 patients were selected and splitted into two groups: 16 HIV-1 positive patients and 17 HIV-1 negative patients and all with chronic periodontitis. The clinical periodontal parameters recorded were: Probing Depth (PD) and Clinical Attachment Level (CAL); the sistemical parameters LTCD4+, LTCD8+ and viral load were analized by the gingival crevicular fluid collected from all patients. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentrations of Interleukin (IL)-10. For the statistical analysis the Student t, Mann-Whitney and Spearman tests were performed. IL-10 levels were significantly lower in both patients groups. Results: There was statistical difference betwen groups for probing depth (p=0.015) and clinical attachment level (p=0.011), no significant correlation was found among the analyzed variables. Conclusion: The IL-10 levels in HIV-1 positive patients had no influence in periodontal and medical parameters.

There are evidences that maternal profile, habits and health knowledge, influence in the oral health of children.
