Effect of educational strategy combined with ART on oral health-related quality of life: a controlled clinical trial.

This study aimed to assess whether complementing atraumatic restorative treatment (ART) with oral health educational strategies (OHES) improves the perception of oral health-related quality of life (OHRQoL) and clinical oral outcomes. A controlled clinical trial included 93 six- to eight-year-old students from five public schools of Piracicaba, Saltinho, and Charqueada municipalities (State of Sao Paulo, Brazil) divided into 3 groups (31 children each) which received: OHES (caries-free), ART (dental caries), and ART plus OHES (dental caries). OHRQoL (CPQ8-10-ISF:16), dental caries, biofilm control, and gingivitis were assessed before and 1 month after interventions by one calibrated examiner. OHES consisted of an educational interactive activity performed once a week for four weeks. Data were analyzed using mixed model ANOVA, Chi-square, and Sign tests. After 1 month of follow-up, improvement in gingivitis status, OHRQoL total score, and Functional Limitations, Emotional Well-Being and Social Well-Being domains scores were found in all groups (p < 0.05). The improvement in biofilm control was observed only in the OHES group (p < 0.001; power = 0.98), while a decrease in Oral Symptoms scores was observed only in ART+OHES group (p <0.001; power = 0.99) and a significant change in the perception of oral health was observed in the two groups that received ART (p < 0.05). In conclusion, improvement in overall OHRQoL and oral status was observed in all children, although the effect of including health educational strategies in the treatment plan was determinant for the perception of an improved oral health after restorative treatment.
