ABSTRACT
AIM:
To investigate the long-term (≥15 years) benefit of orthodontic Class II treatment (Tx) on oral health (OH). SUBJECTS ANDMETHODS:
All patients (Department of Orthodontics, University of Giessen, Giessen, Germany) who underwent Class II correction (Herbst-multibracket Tx, end of active Txâ¯≥ 15 years ago) and agreed to participate in a recall (clinical examination, interview, impressions, and photographs) were included. Records after active Tx were used to assess the long-term OH effects. Data were compared to corresponding population-representative age-cohorts as well as to untreated Class I controls without orthodontic Tx need during adolescence.RESULTS:
Of 152 treated Class II patients, 75 could be located and agreed to participate at 33.7⯱ 3.0 years of age (pre-Tx age 14.0⯱ 2.7 years). The majority (70.8%) were fully satisfied with their teeth and with their masticatory system. The Decayed, Missing, Filled Teeth Index (DMFT) was 7.1⯱ 4.8 and, thus, almost identical to that of the untreated Class I controls (7.9⯱ 3.6). In contrast, the DMFT in the population-representative age-cohort was 56% higher. The determined mean Community Periodontal Index (CPI) maximum score (1.6⯱ 0.6) was also comparable to the untreated Class I controls (1.7⯱ 0.9) but in the corresponding population-representative age-cohort it was 19-44% higher. The extent of lower incisor gingival recessions did not differ significantly between the treated Class II participants and the untreated Class I controls (0.1⯱ 0.2 vs. 0.0⯱ 0.1â¯mm).CONCLUSION:
Patients with orthodontically treated severe Class II malocclusions had a lower risk for oral health impairment than the general population. The risk corresponded to that of untreated Class I controls (without orthodontic Tx need during adolescence).Palavras-chave
