About

The color change of endodontically treated teeth is a common concern in clinical practice. The objective of this study will be to evaluate, in vivo, the color change (ΔE00) caused by endodontic treatment. A randomized clinical trial (RCT) will be conducted with the objective of evaluating ΔE00 originated from epoxy resin (AH Plus) and mineral trioxide aggregate (MTA Fillapex) endodontic sealers, sectioned at the cervical level and 2 mm below, in a period between the immediate endodontic treatment versus after 3, 6 and 12 months.

Full description

The sample syze determined that 48 anterior teeth (incisors and canines) and posterior teeth (premolars) should be included in the study. The sealer and cut will be randomly determined at time of endodontic treatment, originating four groups (n = 12): AH Plus-Cervical, MTA Fillapex-Cervical, AH Plus-2mm and MTA-2mm. The endodontic access cavities will be sealed with resin composed of the color of the dental element. The mean, standard deviation and confidence interval (CI 95%) of the values of ΔE00 obtained for each sealer will be initially analyzed using the variable cut level (cervical or 2mm) using the T test. Indeed, the values of ΔE00 will be analyzed by two-way analysis of variance, where the level of the cut and the type of sealer will be the factors under study.

AH Plus-Cervical

Experimental group

Description:

The objective is evaluate the color change (ΔE00) originated from epoxy resin (AH Plus) endodontic sealer, sectioned at the cervical level. The ΔE00 will be evaluated using the measurements data obtained in a period between the immediate endodontic treatment versus after 3, 6 and 12 months. The values of ΔE00 obtained for each sealer, cut and time will be analyzed by multifactorial analysis to verify associations of the outcomes with the ΔE00.

MTA Fillapex-Cervical

Experimental group

Description:

The objective is evaluate the color change (ΔE00) originated from mineral trioxide aggregate (MTA Fillapex) endodontic sealer, sectioned at the cervical level. The ΔE00 will be evaluated using the measurements data obtained in a period between the immediate endodontic treatment versus after 3, 6 and 12 months. The values of ΔE00 obtained for each sealer, cut and time will be analyzed by multifactorial analysis to verify associations of the outcomes with the ΔE00.

AH Plus-2mm

Experimental group

Description:

The objective is evaluate the color change (ΔE00) originated from epoxy resin (AH Plus) endodontic sealer, sectioned 2 mm below cervical level. The ΔE00 will be evaluated using the measurements data obtained in a period between the immediate endodontic treatment versus after 3, 6 and 12 months. The values of ΔE00 obtained for each sealer, cut and time will be analyzed by multifactorial analysis to verify associations of the outcomes with the ΔE00.
