Study Details

Study Description

Brief Summary

Treatment clinical trial, randomized, controled, parallel, double-blinded, with three groups, that aims to evaluate if there is some advantage in applying surface sealants (Biscover, Bisco, USA or Permaseal, Ultradent, USA) associated with a Bulk Fill Composite (Tetric N-Ceram Bulk Fill, Ivoclar Vivadent,Liechtenstein). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. 53 enrolled patients will receive 159 Class I or Class II dental restorations, made in three different ways, one from each experimental group (no sealant, or one of the evaluated surface sealants). Occlusal or Proximo-occlusal lesions will receive the selected treatments separated by groups. Group Bulk without surface sealant (BNS), Group Bulk and Biscover (BSB), and Group Bulk and Permaseal (BSP). Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

Detailed Description

This is a Treatment clinical trial, randomized, controlled, parallel, double-blinded, with three groups, that aims to evaluate if there is some advantage in applying surface sealants (Biscover, Bisco, USA or Permaseal, Ultradent, USA) associated with a Bulk Fill Composite (Tetric N-Ceram Bulk Fill, Ivoclar Vivadent, Liechtenstein). Volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. All 53 enrolled patients will receive 159 Class I or Class II dental restorations, made in three different ways, one from each experimental group, using the same self-etching adhesive system, under the restorations that will use the same bulk fill composite. All patients must have at only 20 teeth in function, must have at only 3 carious lesion in occlusal or proximo-occlusal face in posterior teeth or old restorations in the same faces, with problems, that need to be changed. Those lesions must be more than 2 mm deep, should have exposed dentin, and must have at only 50% of margins in enamel. Teeth should not present periodontal mobility. Firstly, the patient will be anesthetized locally with 3% Mepivacaine solution, followed by prophylaxis with pumice powder and water. All cavities will be washed and dried after these procedures for optimal selection of color, using a color scale. Then, the rubber dam isolation of the teeth to be restored will be held. Occlusal or Proximo-occlusal lesions will receive the restorative procedurs in 3 different protocols separated by groups. Group Bulk without surface sealant (BNS): the adhesive system will be used in 53 teeth, according to the manufacturer's instructions, in the self-etching mode. The adhesive system will be brushed during 20 seconds in the cavity, will be air-dried during 5 seconds, and photoactivated during 10 seconds with Light Emission Diode (LED) light. Then, the Tetric N-Ceram Bulk fill composite will be used in increments of 4 mm, using the bulk restoration technique, and photoactivated for 40 seconds; Group Bulk and Biscover (BSB): adhesive and restorative procedures will be performed as described in group BNS in 53 teeth. After the restorations are concluded, Biscover surface sealant will be applied according to the manufacturer's instructions; Group Bulk and Permaseal (BSP): adhesive and restorative procedures will be performed as described in group BNS in 53 teeth. After the restorations are concluded, Permaseal surface sealant will be applied according to the manufacturer's instructions. Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Bulk without Surface Sealant

53 teeth will receive restorations using Bulk fill restoration without surface sealant

Procedure: Bulk without surface sealant
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds.

Experimental: Bulk with Biscover

53 teeth will receive restorations using Bulk fill restoration with Biscover surface sealant

Procedure: Bulk with Biscover
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds. After the restoration is completed, biscover surface sealant will be applied according to the manufacturer's instructions.

Experimental: Bulk with Permaseal

53 teeth will receive restorations using Bulk fill restoration with Permaseal surface sealant

Procedure: Bulk with Permaseal
Adhese SE self-etch adhesive system will be applied according to the manufacturer's instructions in 53 teeth.Then, the Tetric N-Ceram Bulk fill composite will be used in increments of no more than 4 mm, using the bulk restoration technique, and each increment will be photoactivated for 40 seconds. After the restoration is completed, Permaseal surface sealant will be applied according to the manufacturer's instructions.

Outcome Measures

Primary Outcome Measures

  1. Restoration Loss [Five years]

    It will be evaluated the increase in the number of losses of dental restorations in the period of five years, verified by periodic visual clinical examination (6/6 months) based on the statement of difference of at least 25% in the amount of remaining restorations in the different groups.

Secondary Outcome Measures

  1. Marginal Pigmentation [Five years]

    It will be evaluated the increase in the number of dental restorations with marginal pigmentation in the period of five years, verified by periodic clinical visual examination (6/6 months) based on the statement of difference of at least 25% in the amount of stained restorations in the different groups.

  2. Post-Operative Hypersensitivity [Five years]

    It will be evaluated the increase in the number of dental restorations with dentin hypersensitivity in the period of five years, verified by periodic clinical examination (6/6 months) based on the statement of difference of at least 25% in the amount of restorations with dentin hypersensitivity in the different groups.

  3. Secondary Caries [Five years]

    It will be evaluated the increase in the number of dental restorations with secondary caries in the period of five years, verified by periodic radiographic examination (6/6 months) based on the statement of difference of at least 25% in the amount of restorations with secondary caries in the different groups.
