Relationship between number of proximal contacts and survival of root canal treated teeth

Abstract

Because RCT teeth with two PCs at access experienced substantially better survival than teeth with fewer than two PCs, the influence of PCs on prognosis should be recognized during treatment planning. Future research should employ prospective study designs, capture additional variables, and provide data to support endodontic treatment decisions.

Influence of proximal contacts and FRC posts on the fracture behavior of premolars with class II composite restorations: An in-vitro study

“…However, in a clinical study on endodontically treated premolars with class II cavities, adhesive restorations with fiber posts were found to be effective over an observation period of 5 years 41) . Regarding the number of proximal contacts, significantly higher load-bearing capabilities were observed only in the groups with additional post insertion (6 and 7); the findings of the already mentioned retrospective clinical study 30) were therefore confirmed under these circumstances. Hypothesis 2 must be rejected for teeth with additional post insertion and be accepted for teeth without posts.…”

“…A retrospective clinical study also revealed a connection between the number of existing proximal contacts and the survival rate of endodontically treated teeth. Accordingly, teeth without proximal contacts fractured significantly more frequently than those with one or two proximal contacts 30) . The objectives of the present in vitro study were to investigate to what extent the number of proximal contacts and the presence or absence of an FRC post had an influence on the fracture resistance of endodontically treated premolars with MOD composite fillings and to evaluate the fracture mode in each case.…”

A systematic review of single crowns on endodontically treated teeth

“…These 18 remaining papers are shown in Table 3. 13,[18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] Of the remaining 18 studies, three were excluded as they were not referring to single teeth and one was excluded for being in a language other than English. Next, one paper was excluded since the follow-up period appeared to be less than 2 years.…”

Restoring the Endodontically Treated Tooth: Treatment Planning Considerations

“…It has been determined that the presence of two proximal contacts had a signifi cant positive impact on the survival rates of endodontically treated teeth (Aquilino and Caplan 2002 ;Caplan et al 2002 ). Caplan et al ( 2002 ) performed a retrospective study in which they reviewed charts and radiographs of 400 teeth from 280 patients.…”

“…Caplan et al ( 2002 ) performed a retrospective study in which they reviewed charts and radiographs of 400 teeth from 280 patients. They suggested that endodontically treated teeth with less than two proximal contacts underperform the ones with two proximal contacts.…”
