Malocclusion severity and its associations with oral health-related quality of life in an adult population

Abstract

Summary Aim The aim of this study was to investigate malocclusion severity and its associations with oral health-related quality of life (OHRQoL) among middle-aged adults. Materials and methods The study material consisted of 1786 subjects from the Northern Finland Birth Cohort 1966 who attended dental and oral examination as part of the 46-year-old follow-up study. Malocclusion severity was assessed using the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and the Peer Assessment Rating index (PAR) from digital 3D dental models. Participants also answered a questionnaire including the Oral Health Impact Profile (OHIP-14) and a question on their satisfaction with occlusal function. Differences between malocclusion severity groups were evaluated for both genders separately. For adjusted models, multivariate Poisson regression models were conducted. Results In this study population, 31.3% had great or very great orthodontic treatment need according to DHC and the mean PAR total score was 22.05. The most severe malocclusions were associated with OHRQoL, especially the psychosocial and handicap dimensions, and satisfaction with occlusal function. There was a significant difference between genders, men having more severe malocclusion but women reporting more OHRQoL impacts. Conclusion One third of the study population were considered to have severe malocclusion. There was an association between malocclusion severity and OHRQoL in adult population, particularly in women.

Impact of malocclusion on oral health-related quality of life in adolescent: Case report

“…In line with this, the Finnish researchers Närhi et al [24], observed from a prospective study, which aimed to investigate the different levels of malocclusion and their associations with quality of life related to oral health in 1786 middle-aged adults who, in addition to the high prevalence of dentofacial alterations, there was a directly proportional association between the severity of malocclusions and quality of life related to oral health, and that women are the most affected ones by this worsening quality of life.…”

Oral-Health-Related Quality of Life (OHRQoL) and Anterior Open Bite in Adult Patients: A Case-Control Study

“…The malocclusions that have the greatest impact on the OHRQoL of patients are anterior crossbite, dental crowding, and Class III malocclusion [ 36 ]. In the scientific literature, there are few articles that analyze the impact of having an anterior open bite on OHRQoL in adult patients, with most evaluating child and/or adolescent patients [ 15 , 16 , 17 , 20 , 21 , 22 ]. This can be explained, in part, by the fact that, today, the majority of orthodontic patients are children; however, increasingly more adult patients are requesting orthodontic treatments.…”

“…Other studies have evaluated the impact of other malocclusions on the oral quality of life of patients [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 35 , 38 ]. Masood M et al in 2014 evaluated the impact of having a posterior crossbite on OHRQoL in young patients (143 patients aged 15–25 years).…”

“…Published studies that analyzed the OHRQoL in orthodontic treatment using the OHIP-14 questionnaire observed that patient scores are lower after finishing treatment [ 13 , 14 ]. Previously published studies examining the influence of a malocclusion on OHRQoL in adults have concluded that there is a direct relationship between malocclusion and OHRQoL [ 15 , 16 , 17 , 18 , 19 ]. However, at present, scientific studies evaluating the impact of having an anterior open bite on OHRQoL are limited to adult patients [ 20 , 21 , 22 ].…”

Hvordan kartlegger og forstår tannhelsepersonell begrepet «store vansker med psykisk og sosial mestring» i forbindelse med bittavvik?

“…Dog, forskningslitteraturen er ikke entydig på den langsiktige nytten av kjeveortopedisk behandling (15). I forbindelse med bittavvik og livskvalitet er det bare dokumentert en svak, inkonsistent relasjon mellom alvorligheten av bittavvik og effekten på livskvalitet (16). Det noen anser for å vaere et kosmetisk bittavvik, kan for andre vaere av stor betydning for livskvalitet.…”
