Impact of occlusal scheme on gingival recession – a pilot study

Aim: Correlation between gingival recession and impact of occlusion is still inconclusive. Aim of this clinical study was to determine if occlusal scheme has an impact on gingival recessions on the buccal side in final year dental students of University of Zagreb. Material and Methods: There were 35 participants in this pilot study (mean age 23, 8 years). Their oral hygiene habits and periodontal indices were recorded (API, BOP, PD and GR). A comprehensive analysis of occlusion was done with shimstock foil (contacts during left and right laterotrusion on 3 mm). Canines and premolars during contact on working side while in laterotrusion movement in all quadrants were compared with same teeth that weren’t in contact. Results are expressed as medians (interquartile range). Intergroup comparisons were made using Mann-Whitney U-test due to small sample size. P values <0.05 was considered statistically significant. Results: There were 12 defined groups (canines, first and second premolars in four quadrants). Statistically significant difference was found in one group (lower right canine, p<0, 01). 25 lower right canines in contact and in right laterotrusion showed higher value of gingival recession (0.5, 0-1) compared to 10 canines when not in contact (0, 0-0). The rest of groups showed differences, but they were not statistically significant. Conclusion: There appears to be no significant evidence that the concept of occlusion has any impact on appearance of gingival recessions. It should be considered that this is a pilot study, and the result of lower right canine and relatively small number of participants indicate that further study is needed.
