Impact of malocclusion treatments on Oral Health-Related Quality of Life: an overview of systematic reviews.

OBJECTIVE: To perform an overview of systematic reviews (SR) assessing the impact of malocclusion treatments (Orthodontic Treatment - OT and/or Orthodontic Surgical Treatment - OST) on Oral Health-Related Quality of Life (OHRQoL). MATERIALS AND METHODS: A search strategy was conducted in electronic databases until June 7th, 2021, followed by a manual search in grey literature and registration databases. Two independent authors applied the eligibility criteria, extracted the data, assessed the risk of bias (AMSTAR-2), and performed the certainty of evidence (GRADE) evaluation. Meta-analysis was planned to be carried out in RevMan 5.3 (with 95% confidence intervals (CI) considering p < 0.05), in case of homogeneous studies considering OHRQoL instrument and time of follow-up. RESULTS: A total of 126 articles were accessed on the database, 18 registers, 33 records on grey literature and 3 articles by means of citation searching. After duplicates removal and eligibility criteria analyses, 15 SR were included. From that, 13 showed improvement in OHRQoL after OT and/or OST. The methodological quality ranges from high (n = 2), to critically low (n = 9). Meta-analysis was conducted. Improvement on OHRQoL after a 6-month OST using the OQLQ-22 (p < 0.00001; 19.65; CI: 12.60-26.70) and OHIP-14 instruments (p < 0.00001; 10.70; CI: 9.89-11.51); and after a 6-month OT using the CPQ 11-14 instrument (p = 0.010; 3.57; CI: 0.86-6.28) with very low certainty of the evidence for all outcomes was observed. CONCLUSIONS: Although most SR selected in this overview are characterized by a critically low quality, as well as very low certainty of the evidence, OT and/or OST seem to have a positive impact in improving the OHRQoL. CLINICAL RELEVANCE: The overview of existing systematic reviews compiled that OT and/or OST seem to have a positive impact on improving the OHRQoL. This information will facilitate clinical decision-making considering the clinical and psychological parameters.

The impact of traumatic dental injury on sensory perception and oral health-related quality of life of a child/adolescent before and after the treatment with aesthetic prosthesis: case report.

Children and adolescents are most frequently affected by Traumatic Dental Injuries (TDIs). Scientific evidence shows that TDIs have a negative impact on the oral health-related quality of life (OHRQoL) of children/adolescents and their families. This article aimed to report two cases of avulsion and how the treatment influenced the oral sensory perception and OHRQoL. Two patients (8 and 14 years) from a "Dental Trauma Care Program" (DTCP) presenting avulsion were evaluated. The stereognosis test assessed oral sensory perception. This test obtains the average of right and wrong answers, as well as the time spent to perceive 6 silicone objects with different geometric shapes. Child Perceptions Questionnaire (CPQ) was applied to evaluate the OHRQoL through interviews. Based on the two reports, it was possible to observe a satisfactory improvement in the OHRQoL of the child/adolescent and their families. TDI influenced negatively the oral sensory perception of both patients. Since the aesthetic prosthesis did not entirely improve the patients' oral tactile perception, it may be considered a temporary solution.
