Influence of Resin Cement Composition on the Longevity of Intraradicular Post of Endodontically Treated Teeth

Influence of Resin Cement Composition on the Longevity of Intraradicular Post in the Rehabilitation of Endodontically Treated Teeth - Randomized Clinical Trials

The aim of this study is through a randomized clinical trial, double blind, splithmouth, evaluate the success rate (post or dental crown displacement; fracture of the core/post/crown; marginal integrity and absence of endotontic alterations) of definitive indirect crowns un endodontically treated teeth. The composition of the resin cement (with and without mineral trioxide aggregate) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.

Endodontically treated teeth present an increased risk of fracture and are usually related to extensive carious processes or trauma that promote major coronary destruction. In such situations, it may be necessary to indicate intra-radicular retainers, such as fiberglass pins, to retain the restorative material. The aim of this study is through a randomized clinical trial, double blind, splithmouth, evaluate the success rate (post or dental crown displacement; fracture of the core/post/crown; marginal integrity and absence of endotontic alterations) of definitive indirect crowns un endodontically treated teeth. The composition of the resin cement (with and without mineral trioxide aggregate) will be evaluated. Twenty participants with at least two teeth with endodontic treatment with need intraradicular post cementation and confection of indirect dental crown (each participant) will be selected. The teeth will be randomly divided into 2 different groups according to resin cement composition (with and without mineral trioxide aggregate). Data will be collected, tabulated and submitted to statistical analysis.

Insertion of the cement on the root canal and on post surface. Light-cured for 40 seconds on each surface.

Insertion of the cement on the inner surface of the crown. Light-cured for 40 seconds on each surface.

Success rate (post or dental crown displacement; fracture of the core/post/crown; marginal integrity and absence of endotontic alterations) of definitive indirect crowns with a 1 year follow up.

Inclusion Criteria: Healthy volunteers; Presence of at least two teeth with endodontc treatment; Presence of at least two teeth with indication of total crowns; Good oral hygiene. Exclusion Criteria: Dentures or orthodontics; Presence of periodontal disease Presence of parafunctional habits Presence of systemic disease Constant use of analgesic and or anti-inflammatory Allergic response to dental products
