Abstract
Background and Objectives: Dental occlusion and gingival recession have been studied over the past years especially because of the increasing incidence of occlusal interferences in young patients. The purpose of this pilot study is to investigate any association between occlusal dysfunctions and gingival recessions. Data on gingival phenotype and previous orthodontic treatment were also collected to assess any correlation with the presence of gingival recession. Materials and Methods: Forty systemically healthy subjects, without signs of periodontitis and with gingival recessions, were included in the study. The following parameters were determined: location and extent of the gingival recession, gingival phenotype and functional occlusion by means of observing and registering the occlusal contacts in maximum intercuspation position, protrusive and lateral guidance. Results: Premolars were mostly affected in cases of working-side interferences during lateral guidance (71.19% of the affected teeth during left and 75% during right mandibular movements). The chi-squared exact test applied for the analysis of contingency tables revealed statistically significant associations between excursive interferences during lateral guidance and anterior guidance and the presence of gingival recession on the involved group of teeth. Conclusions: The results suggest that most gingival recessions might be associated with working-side interferences, the highest number of gingival recessions being associated with active interferences during lateral guidance.
Highlights
IntroductionGingival recessions are defined as apical displacement of the gingival margin beyond the cementoenamel junction; they appear either as a response against local irritating factors (such as biofilm, calculus, oral piercing, etc.) or as incapacity of the gingival mucosa to adapt to excessive occlusal forces [1]

The present study aims to evaluate the incidence of occlusal interferences in young patients with gingival recession and no other signs of gingival inflammation or periodontitis
Summary
Gingival recessions are defined as apical displacement of the gingival margin beyond the cementoenamel junction; they appear either as a response against local irritating factors (such as biofilm, calculus, oral piercing, etc.) or as incapacity of the gingival mucosa to adapt to excessive occlusal forces [1]. Gingival recessions cannot be associated with a single etiologic factor, which makes the clinical diagnostic and treatment even more difficult [2]. Several factors, such as age, oral hygiene, or gingival phenotype, may influence the incidence and progression of gingival recessions. Dental occlusion and gingival recession have been studied over the past years especially because of the increasing incidence of occlusal interferences in young patients. The purpose of this pilot study is to investigate any association between occlusal dysfunctions and gingival recessions. Conclusions: The results suggest that most gingival recessions might be associated with working-side interferences, the highest number of gingival recessions being associated with active interferences during lateral guidance
