IN20-191 Association between Food Impaction and Peri-implant Soft Tissue Condition at Proximal Space between Implant Supported Single Crown and Natural teeth

Abstract
The purpose of this study was to investigate the association of food impaction at proximal space between implant supported single crown (ISSC) and natural teeth and peri-implant soft tissue condition. Patients with ISSC coming for implant checkup at the Faculty of Dentistry, Chulalongkorn University between July 2019 and December 2019 were recruited. Food impaction was evaluated by either patients’ experience or clinical examination of food wedging in the proximal space. Peri-implant soft tissue inflammation was recorded when there was bleeding on probing (BOP) at ISSC site. In addition, proximal contact tightness, level of papilla appearance, plaque presence, pocket depth and keratinized mucosa width were also assessed. The association between food impaction and the presence of BOP was analyzed by Chi-square test and considered significant at P<0.05. Total 302 proximal spaces of 215 ISSC in 132 patients were examined. Among 302 proximal spaces contact tightness, level of papilla appearance, plaque presence and keratinized tissue width found no association with BOP. Nevertheless, there was significant association between probing depth and BOP (P<0.001). However, BOP was not associated with food impaction (P=0.864). In conclusion food impaction between ISSC and natural teeth peri-implant soft -tissue inflammation was not associated with peri-implant soft tissue inflammation.

Like in your review, food impaction facilitate plaque accumulation that lead to more gingival inflammation. In order to form plaque, food need to trap in proximal contact at least 24 hours. So, the cleaning habit of your subject definitively have impact on this process. Once your subject have food impaction, how can you control them not to remove the food immediately or at least 24 hours to really see the effect of plaque?
Daer Researcher,
Thank you for your great presentation.
I just have a quick question. Do you have some criteria of choosing the adjacent teeth? I am wondering the improper condition of adjacent teeth may affect the soft tissue at the proximal site.
Best regards,
Win
Dear VITTAWIN DECHOSILPA
Thank you for your question.
Subject’s cleaning habit was a confounding factor in this study. We should set the regiment that food impaction is not removed at least 24 hours before the day of oral examination to observe the effect of plaque. On the other hand, we could note how long the food impaction has been removed before the patients come to have clinical examination for further analysis. However, we do not control this factor and this could affect the result in this study. This would be applied for future study.
Dear WIN HIRIOTAPPA,
Thanks for your question.
Adjacent teeth with severe periodontitis were excluded in this study.
