Eligibility
Age
18 Years to 70 Years
Inclusion criteria
Inclusion criteria: Participants aged 18–70 years; participants clinically healthy; participants presenting at least 20 teeth in occlusion and an acceptable level of oral hygiene; each participant must require at least two Class I or II restorations in vital teeth with cavities of similar horizontal and vertical dimensions; the selected teeth must present functional occlusion with the natural antagonist tooth and proximal contact with adjacent teeth; pulp vitality will be confirmed by means of a thermal test using a cold spray and periapical radiography; a positive response will be considered when it occurs within 10 seconds after stimulus application and is characterized by mild, short-lasting pain, consistent with a vital pulp
Exclusion criteria
Exclusion criteria: Participants that present unsatisfactory oral hygiene characterized by a Simplified Oral Hygiene Index greater than 3; participants diagnosed with chronic or advanced periodontitis, defined as probing depth greater than 4 mm, presence of bleeding on probing, participants with clinical attachment loss greater than 3 mm in more than four teeth; participants with fixed orthodontic appliances; participants that present significant occlusal wear in more than 10 posterior teeth; participants that require endodontic treatment; participants that presente hypersensitivity to resin-based composite materials or to any other materials used in this study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare the clinical performance of a rapid, high intensity photoactivation restorative system in posterior teeth using a bulkfill composite resin. | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the functional properties (fracture and retention, marginal adaptation, wear, proximal contact, radiographic evaluation [when necessary], and patient-reported outcomes) of posterior restorations using Tetric N-PowerFill 2 composite resin, lightcured for 3 s at 3050 mW/cm² versus lightcured for 10 s at 1069 mW/cm², at baseline, 6 months, and at 1, 2, 3, 4, and 5 years;To evaluate the esthetic properties (marginal discoloration, surface discoloration, surface gloss, color stability, and anatomical form) of posterior restorations using Tetric N-PowerFill 2 composite resin, lightcured for 3 s at 3050 mW/cm² versus lightcured for 10 s at 1069 mW/cm², at baseline, 6 months, and at 1, 2, 3, 4, and 5 years.;To evaluate the biological properties (postoperative sensitivity, secondary caries, tooth integrity, periodontal response, and oral health) of posterior restorations using Tetric N-PowerFill 2 composite resin, lightcured for 3 s at 3050 mW/cm² versus lightcured for 10 s at 1069 mW/cm², at baseline, 6 months, and at 1, 2, 3, 4, and 5 years. | — |
