Evaluation Of the BEAUTIBOND XTREME Adhesive in Class I and II Restorations: One-Year Results.

March 20, 2025 updated by: Larissa Fernanda Pereira, University of Sao Paulo

A Randomized Prospective Clinical Study Evaluating the Effectiveness of the BEAUTIBOND XTREME Adhesive System Using Different Bonding Techniques in Class I and II Restorations: One-Year Results.

This randomized clinical trial aimed to evaluate the performance of the Beautibond Xtreme adhesive system under different bonding techniques. Patients over 18 years old with restorative needs were selected, and 152 teeth were randomized using the "Research Randomizer Program" for allocation into control groups (CI - Class I restoration with total-etch conditioning; CII - Class II restoration with total-etch conditioning) and test groups (TI - Class I restoration in self-etch mode; TII - Class II restoration in self-etch mode; TIII - Class I restoration with selective enamel etching; TIV - Class II restoration with selective enamel etching). The restorations were evaluated (USPHS criteria) regarding anatomy, integrity, marginal staining, color, roughness, secondary caries lesions, postoperative sensitivity, and retention. Two calibrated examiners (Kappa test 0.84), blinded to the treatments, conducted evaluations for up to one year.

Experimental: CI: Class I cavities restored with the total acid-etching technique.
Class I cavities restored with the total acid-etching technique.
Other: Group CI and CII - BeautiBond Xtreme (total-etch technique) + Beautifil LS
the enamel was etched for 30 seconds and the dentin for 15 seconds using 35% phosphoric acid gel (Ultradent). The acid was then rinsed off, and excess moisture was removed with an air spray. To protect the dentin during air blasting, an absorbent paper was held over it using clinical tweezers, ensuring a whitish appearance for the enamel and slightly moist dentin. Excess water on the cotton roll was dried as well. The BeautiBond Xtreme adhesive system was applied without any waiting time, followed by a gentle air spray for 3 seconds and then a strong air blast to ensure solvent evaporation. Finally, the adhesive was light-cured for 5 seconds using a LED photopolymerizer (Gran Valo LED Curing Light, Ultradent).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Anatomic Form
Time Frame: baseline, six months, and one year.
The anatomic form of the restoration was evaluated according to the modified United States Public Health Service (USPHS) criteria at baseline, six months, and one year. Restorations were classified as Alpha (continuity of the restoration with the existing anatomic form), Bravo (continuity of the restoration with partial degradation but clinically acceptable), or Charlie (continuity of the restoration compromised, requiring replacement).
baseline, six months, and one year.
Marginal Adaptation
Time Frame: baseline, six months, and one year.
Marginal adaptation was visually analyzed using an explorer to detect crevices or marginal failures. Classifications included Alpha (no visible evidence of a crevice along the margin), Bravo (visible evidence of a crevice along the margin where the explorer can penetrate or catch), and Charlie (the explorer penetrates the crevice, exposing dentin or base).
baseline, six months, and one year.
Marginal Discoloration
Time Frame: baseline, six months, and one year.
Marginal discoloration was assessed by recording any color changes at the interface between the restoration and tooth structure. Restorations were classified as Alpha (no visible discoloration), Bravo (discoloration present but not penetrating along the margin in a pulpal direction), or Charlie (deep discoloration penetrating along the margin toward the pulp).
baseline, six months, and one year.
Secondary Caries
Time Frame: baseline, six months, and one year.
The presence of secondary caries was clinically and radiographically evaluated throughout the study. Restorations were classified as Alpha (no evidence of secondary caries) or Charlie (evidence of secondary caries around the restoration, requiring replacement).
baseline, six months, and one year.
Color Match
Time Frame: baseline, six months, and one year.
Color match was evaluated by comparing the restoration to the adjacent tooth structure in terms of color and translucency. Classifications included Alpha (color and translucency compatible with the tooth structure), Bravo (color and translucency mismatch within the acceptable range), and Charlie (color and translucency mismatch outside the acceptable range).
baseline, six months, and one year.
Postoperative Sensitivity
Time Frame: baseline, six months, and one year.
Postoperative sensitivity was assessed through patient reports at different study periods. Classifications included Alpha (no postoperative sensitivity after the restorative procedure and throughout the study), Bravo (slight sensitivity at any stage of the study), and Charlie (severe sensitivity at any stage of the study).
baseline, six months, and one year.
Surface Texture
Time Frame: baseline, six months, and one year.
The surface texture of the restoration was visually and tactilely evaluated using an explorer. Restorations were classified as Alpha (no surface defects), Bravo (minimal surface defects), or Charlie (severe surface defects on the restoration).
baseline, six months, and one year.
Retention
Time Frame: baseline, six months, and one year.
Retention was evaluated by verifying the presence of the restoration over time. Classifications included Alpha (no loss of restorative material) and Charlie (fracture and/or total loss of the restorative material).
baseline, six months, and one year.
