Periodontal status of teeth restored with crowns and their contralateral homologues, Valdivia. Chile.

Abstract

Aim: To determine periodontal status of fixed single prostheses (FSP) installed in 2013 at Austral University of Chile, and its contralateral homologue (CH). Methods: A group of patients with FSP installed during 2013, who met the selection criteria and agreed to participate in the study were evaluated. Probing depth, attachment level; bleeding on probing and dental plaque index for each FSP and CH were measured in 2014; biological width invasion was also evaluated. One FSP and one CH were measured per patient, and in 6 sites for each tooth. Results: Seventy-four patients were evaluated. The majority were women (73%); posterior teeth accounted for 63.5%. The majority of participants had history of previous periodontal disease (85.1%), of which 58.7% was Periodontitis. Six of the patients with a history of gingivitis progressed to periodontitis (23.07%); while 100% of patients with no history of periodontal disease maintained their condition. Only 4 of the FSP evaluated showed biological invasion width. Discussion: Similar results were found for FSP and CH teeth with respect to probing depth, clinical attachment level and bleeding on probing. However, a difference in relation to dental plaque index was observed: positive in 58.1% CH and positive in 29.7% FSP. Under the conditions of this study, it is concluded that the periodontal status of teeth with FSP does not differ from CH.
