Oral health-related quality of life and orthodontic treatment seeking.

INTRODUCTION: The aim of this study was to assess oral health-related quality of life (OHQOL) in adolescents who sought orthodontic treatment. A comparison between these adolescents and their age-matched peers who were not seeking orthodontic treatment provided an assessment of the role of OHQOL in treatment seeking. METHODS: The sample consisted of 225 subjects, 12 to 15 years of age; 101 had sought orthodontic treatment at a university clinic (orthodontic group), and 124, from a nearby public school, had never undergone or sought orthodontic treatment (comparison group). OHQOL was assessed with the Brazilian version of the short form of the oral health impact profile, and malocclusion severity was assessed with the index of orthodontic treatment need. RESULTS: Simple and multiple logistic regression analysis showed that those who sought orthodontic treatment reported worse OHQOL than did the subjects in the comparison group (P <0.001). They also had more severe malocclusions as shown by the index of orthodontic treatment need (P = 0.003) and greater esthetic impairment, both when analyzed professionally (P = 0.008) and by self-perception (P <0.0001). No sex differences were observed in quality of life impacts (P = 0.22). However, when the orthodontic group was separately evaluated, the girls reported significantly worse impacts (P = 0.05). After controlling for confounding (dental caries status, esthetic impairment, and malocclusion severity), those who sought orthodontic treatment were 3.1 times more likely to have worse OHQOL than those in the comparison group. CONCLUSIONS: Adolescents who sought orthodontic treatment had more severe malocclusions and esthetic impairments, and had worse OHQOL than those who did not seek orthodontic treatment, even though severely compromised esthetics was a better predictor of worse OHQOL than seeking orthodontic treatment.

Oral health-related quality of life in orthognathic surgery patients.

INTRODUCTION: In the last decade, an increasing number of studies focusing on the impact of oral deformities and illnesses on quality of life have been published. Our goal was to evaluate the impact of oral problems on quality of life in 3 groups of adult patients in need of orthognathic-surgical treatment. METHODS: A total of 117 patients were recruited from the Clinic of Oral and Maxillofacial Surgery of the State University of Rio de Janeiro in Brazil: 20 in the initial phase, 70 in the presurgical phase (presurgical orthodontic preparation), and 27 in the postsurgical phase. The impact of treatment phase on oral health-related quality of life was evaluated with the oral health impact profile (OHIP-14). OHIP-14 scores were calculated by an additive method, and the participants were divided on the basis of level of impact into 2 groups: high impact (scores, >11) and low impact (scores, < or =11). RESULTS: Compared with patients in the postsurgical phase, those who needed orthognathic surgical treatment but had not yet begun it and those who were in the presurgical phase of treatment were 6.48 and 3.14 times more likely, respectively, to experience a negative impact of their oral condition. CONCLUSIONS: Among those undergoing or anticipating orthognathic-surgical treatment, orthognathic surgery positively affects the patients' quality of life.

A comparison of the dental health of Brazilian and Canadian independently living elderly.

OBJECTIVE: To compare the dental status of Brazilian and Canadian elderly populations with respect to socioeconomic and quality of life factors. MATERIALS AND METHODS: A total of 496 adults aged 60-75 years, having four or more teeth, and physically and cognitively suitable for a clinical oral examination were included. Subjects answered questions concerning their lifestyle and completed the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. RESULTS: In all populations, the majority were females, aged between 60 and 65 years and married. Although the Canadian New Immigrant population had lower mean income, they had more remaining teeth (23.04 ± 6.1), more functional teeth (sound and restored teeth) (14.92 ± 5.7), more sound teeth (15.40 ± 7.6), but more carious teeth (2.97 ± 3.0). The Brazilian population had higher numbers of restored teeth (12.26 ± 6.8) and fewer remaining teeth (17.80 ± 7.6). In all populations, females, married and younger (60-65 years old) adults were more likely to retain 20 or more teeth. The mean GOHAI scores were similar for Canadians (40.55 ± 5.7) and Canadian New Immigrants (39.28 ± 6.5), but were higher than that among Brazilians (31.97 ± 8.9). CONCLUSIONS: The numbers of remaining teeth were related to greater education and higher income status for Brazilian and Canadian populations. However, Canadian New Immigrants with lower income and education retained more teeth than the other populations.
