Resumen
Different types of malocclusion and their treatments may influence the oral health-related
quality of life (OHRQoL) of patients. In view of the foregoing, this thesis was composed of
two articles. The first article evaluated a convenience sample of adolescent patients, with
regard to their malocclusion, determined by the adolescents themselves, impact on their oral
health-related oral health, in addition to comparing this with the normative evaluation made
by the orthodontist. The second article evaluated the changes in OHRQoL in 55 adolescents
in the age-range between 11 and 14 years, throughout the course of corrective orthodontic
treatment, by means of a clinical study. In this study, OHRQoL was evaluated in the
following time intervals: pre-treatment (T0), one week after treatment began (T1), one month
(T2), three months (T3) and six months after orthodontic treatment began (T4). In both
studies, innumerable variables were collected. The OHRQoL was evaluated by means of the
Brazilian version of the Child-Oral Impacts on Daily Performances (Child-OIDP). Selfperception
and normative evaluation by the orthodontist was assessed by means of the Index
of Orthodontic Treatment Need - IOTN). The socio-economic variables were collected by
means of a structured questionnaire;. Descriptive analysis of the sample was made to
demonstrate the socioeconomic characteristics, and tests were performed to verify the
normality of the sample data. Afterwards, the mean values of the different experimental time
intervals were compared by means of the paired Wilcoxon test, to evaluate the changes in
OHRQoL. The ratio between orthodontic treatment need and the oral health-related quality of
life was evaluated by using the ANOVA test. Comparison between the normative and
subjective aspic of the IOTN was obtained by means of the Fisher Exact test. The Oral healthrelated
quality of life underwent changes in the different stages of corrective orthodontic
treatment; deteriorating in the first week and in the time interval of one month after beginning
with orthodontic treatment. After this it improved continually after three and six months of
orthodontic treatment when compared with the beginning of orthodontic treatment.
Furthermore, we concluded that the quality of life was shown to be worse in patients with
extensive orthodontic treatment need, according to both the patient’s self-perception and
orthodontist’s normative assessment, when compared with patients who had little or moderate
orthodontic treatment needs.
