OBJECTIVE: To evaluate if facial type is a predictor of the development of gingival recession.

METHODS: A cohort of 179 orthodontic patients (76 males, 101 females; age before

treatment T S = 12.4 years, SD = 0.8) were followed until 5 years post-treatment

(T 5 = 20.7 years, SD = 1.2). The presence of recessions was scored (‘Yes’ or

‘No’) by two raters on initial (T S), end of treatment (T 0), and post-treatment

(T 5) plaster models. A recession was noted (scored ‘Yes’) if the labial

cemento-enamel junction was exposed. The clinical crown heights were measured at

T S, T 0, and T 5 as the distances between the incisal edges and the deepest

points of the curvature of the vestibulo-gingival margins. Determination of the

facial type was based on the inclination of mandibular plane relative to cranial

base (Sella-Nasion/Mandibular Plane) and the proportion of posterior to anterior

face heights (PFHs; SGo/NMe × 100 per cent) on pre-treatment cephalograms.

RESULTS: From T 0 to T 5, the number of subjects with recessions increased from

2 (1.1 per cent) to 24 (13.6 per cent), and the number of recession sites

increased from 2 to 39. However, most patients had either one or two recession

sites. The mean clinical crown height of mandibular incisors increased by 0.86mm

(SD = 0.82, P < 0.001). Regression analysis showed that mandibular plane

inclination had no effect on the development of gingival recession or on the

increase of clinical crown heights of mandibular incisors.

CONCLUSIONS: Facial type is not a predictor of the occurrence of gingival

recession.
