Prevalence and severity of vestibular recession in mandibular incisors after orthodontic treatment: A case-control retrospective study

Objective:To assess the prevalence and severity of vestibular gingival recession of mandibular incisors after orthodontic treatment and to evaluate possible contributing factors.Materials and Methods:From the record pool of patients who completed orthodontic treatment from 1999–2006 at the Department of Orthodontics, University of Oslo, Norway, 588 patients fulfilled the inclusion criteria. Intraoral color slides were used for the evaluation of gingival recessions (based on Miller classification), presence of visible plaque, and gingival inflammation. Cephalometric radiographs were used to assess the sagittal intermaxillary relation, mandibular and intermaxillary angles, and the position of the lower incisors. A control group was drawn from the same pool of 588 patients. All statistical analyses were performed using SPSS.Results:The prevalence of gingival recessions after orthodontic treatment was 10.3%. Most (8.6%) were classified as Miller Class I, and 1.7% were classified as Miller Class II. Gingival recession was predominantly found on central incisors. Reduction of the sagittal intermaxillary angle and retroclination of the lower incisors was correlated with the development of a more severe gingival recession.Conclusions:The present study indicates that vestibular gingival recession of mandibular incisors after orthodontic treatment is of minor prevalence and severity. The presence of gingival recession or retroclination of the incisors with mesial basal relations increases the risk of more severe gingival recession.

Gingival Condition Associated with Partial Orthodontic Treatment

A longitudinal clinical study on gingival condition was made on seventy-five patients treated with fixed orthodontic appliances in one or both dental arches. Fifty-three non-treated subjects of comparable age were included for further reference. The prevalence and severity of gingivitis about the maxillary teeth were compared for partial (i.e. banding of all maxillary teeth) and full (i.e. banding of all maxillary and mandibular teeth) orthodontic treatment. Plaque accumulation and gingival status were assessed according to the Plaque and Gingival Index systems. Gingival hyperplasia was recorded by linear measurements using pocket probes.

The results demonstrated that all patients developed generalized gingivitis during the period of active treatment. The proximal areas were invariably more affected than the buccal areas, and posterior teeth more than anterior teeth. Although the GI, PII and pocket depth values were constantly lower when treatment was limited to the maxillary teeth, the differences were small and generally not significant. Also the healing of the gingiva after removal of the appliances was more rapid when partial treatment was used. In neither orthodontic group, however, any permanent damage to the periodontal tissues could be demonstrated with the methods used.     

The Influence of Occlusal Trauma on Gingival Recession and Gingival Clefts

The aim of this study was to investigate the centric occlusal contact pattern in maximum intercuspation and to study the nature of occlusal contacts during maximum intercuspation to protrusive, lateroprotrusive and lateral excursive movements. Fifty subjects having gingival recession and ten subjects having gingival clefts belonging to age group of 18–25 years were selected after obtaining informed consent from the student’s population. The selected subjects were examined and the location and extent of gingival recession, gingival clefts and occlusal wear facets were recorded. The type of occlusion and the nature of occlusal contact in maximum intercuspation and eccentric mandibular movements were also recorded using articulating foil and shimstock. Chi square test, Fisher’s exact test (F) and Z test were used to statistically analyse the data obtained. Among the three occlusal concepts, gingival recession was more commonly related to group function than to canine protected occlusion. Canine protected occlusion was associated with gingival recession on the labial surface while in group function occlusion; the recession was distributed equally on the facial surface of the anterior as well as posterior teeth. Nearly all subjects showed interferences in protrusive, lateroprotrusive and lateral excursive movements on teeth showing gingival recession and gingival clefts. Occlusal wear was seen on all teeth having gingival clefts and on most teeth having gingival recession. These results suggest that occlusal interferences in maximum intercuspation and eccentric movements in one form or the other and absence of mutually protected occlusion can contribute to gingival lesions such as gingival recession and clefts.
