NCT03924830

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.

Outcome Measures

Primary Outcomes (1)

  • Restoration Loss

    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.

    Five years

Secondary Outcomes (3)

  • Marginal Pigmentation

    Five years

  • Post-Operative Hypersensitivity

    Five years

  • Secondary Caries

    Five years

Study Arms (3)

Bulk without Surface Sealant

ACTIVE COMPARATOR

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

Procedure: Bulk without surface sealant

Bulk with Biscover

EXPERIMENTAL

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

Procedure: Bulk with Biscover

Bulk with Permaseal

EXPERIMENTAL

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

Procedure: Bulk with Permaseal

Interventions

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.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • All patients must have at only 20 teeth in function, must have at only 3 carious occlusal or proximo-occlusal lesions, or old restorations that need to be changed, in different teeth. 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.

You may not qualify if:

  • Volunteers with periodontal disease; with gingival bleeding; use of anti-inflammatory drugs in the last 30 days.
