Estudo retrospectivo da efetividade de uma abordagem de tratamento não invasiva para inativação de lesões de cárie dentária não cavitadas em pacientes infantis

ABSTRACT Inactivation of non cavitated caries lesions occurs mainly with the triad: oral hygiene, diet control and use of fluoride. The objectives of this retrospective study were: to evaluate the efficacy of a non-invasive treatment approach for the inactivation of non-cavitated lesions of deciduous and permanent teeth performed at the Child and Adolescent Clinic of the Faculty of Dentistry of the Federal University of Rio Grande do Sul (FO-UFRGS), identifying the clinical factors of the patient and associating them with the clinical success of the treatment. We included 98 medical records of patients who received topical fluoride applications (TFA) in the FO-UFRGS between 2016 and 2018. Demographic and clinical data were also collected regarding evaluation of caries activity in the initial consultation and after the treatment, visible plaque index (VPI), gingival bleeding index (GBI) and dmf-t/ DMF-T. In addition, the patients who did not complete the treatment were quantified in which session the TFA treatment was discontinued and whether the patient returned for treatment or not. After analysis, 55 records were allocated to group 1 (patients who completed treatment) and 43 records to group 2 (patients who did not complete the treatment). There was no statistical significance difference when comparing the variables age, gender, IPV, ISG and ceo-d / CPO-d with the success of the treatment. There was a statistically significant difference comparing the initial VPI with the final (p = 0.016) and number of initial and final active non-cavitated lesions (p = 0.000), but there was no difference for the initial and final GBI (p = 0.324). Based on the findings of VPI reduction and reduction in the number of non-cavitated lesions active at the end of treatment, it is suggested that the protocol of non-invasive treatment for inactivation of non-cavitated caries lesions applied in the CIJ of FO-UFRGS is effective.   Keywords: Dental Caries.
