The objective is to present the efficacy of this line of treatment in patients with Autism Spectrum Disorder (ASD). Case report: Signed informed consent form. Male patient, 8 years 3 months, ASD, ADHD and Language Disorder. Treatment with Risperidone. Mixed dentition first stage, high cariogenic risk. The dental treatment was performed using the concept of minimal intervention.  For the treatment of caries there are several methods, one of which is anxiety. This treatment allows the primary tooth to remain in function over time and in conditions similar to those achieved by conventional restorative treatment. This type of intervention is adjusted to the needs of the patient with disabilities, achieving the restoration of oral health, thus benefiting their adherence to dental treatment, improving the acceptance of the patient and his family. Conclusion: Minimal intervention therapy is an excellent treatment option for patients with disabilities. The current literature does not describe significant differences between conventional treatment and minimal intervention. The treatment of choice should be according to the specific needs of each case and associated risk, looking for the best alternative to restore oral health and improve the quality of life.esMedicineIntervention (counseling)AutismRisperidoneAutism spectrum disorderAnxietyQuality of life (healthcare)article
