Remoção seletiva químico-mecânica do tecido cariado dentinário em paciente com transtorno de processamento sensorial: relato de caso clínico

Abstract

Sensory Processing Disorder (SPD) is a condition in which the brain has difficulty to process stimulation from the environment and from the human senses. SPD patients report that sensory experiences such as bright lights and loud noises trigger and/or amplify their psychological symptoms, which makes dental offices a very intense environment for these individuals. In dentistry, conservative techniques for the treatment of carious lesions have proven to be a good intervention alternative. In this scenario, the use of chemical agents is intended to help professionals in the selective removal of decayed tissue, replacing the use of rotary instruments. The objective of this report is to evaluate the effectiveness and acceptance of the patient with SPD to the chemical-mechanical removal of dentin carious tissue. Patient, female, 9 years old, presents with SPD. On clinical examination, a carious lesion in the dentin was found on element 65, on the palatal surface. 0.1ml of BRIX3000 was applied in the cavity for 2 minutes, washed with plenty of water and dried with sterile cotton. After the application protocol, the complete removal of the contaminated carious tissue was performed with a dental spoon No. 0, without the use of anesthetic and rotary instruments. The tooth was restored with light-curing glass-ionomer cement (Riva, SDI). At the end of the restorative protocol, using a visual scale, the patient reported a zero score for pain. After three months of follow-up, the restoration had to be redone. subsequently, it remained without adhesive failures for another three months, totaling six months of follow-up. Thus, the BRIX3000 presented itself as an efficient alternative to the use of rotary instruments for the treatment of carious lesions, especially for patients with TPS. However, larger tests must be carried out to confirm the hearing of the product, mainly involving the interaction with the adhesiveness of the most used restorative materials.
