G-aenial Bond & G-aenial Universal Flo:V Class Clinical Evaluation

Objective: To evaluate the clinical outcome of Class V restorations performed using the all-in-one adhesive G-aenial Bond (GC , Tokyo, Japan)  with and without selective enamel etching, in combination with the flowable resin composite G-aenial Universal Flo (GC, Tokyo,Japan).

Method: Patients were selected depending on the following parameters: age ≥18 years, good general health, need of 1-2 buccal Class V restoration, no decayed-Class V cavities and Class V cavities' gingival wall above the gingival margin. Patients' written consent to the trial was obtained. Ethical Committee Approval of Siena University was delivered.  A sample of 80 teeth was collected: 2 groups of 40 teeth were randomly formed. In Group 1 adhesive application was preceded by preliminary phosphoric acid etching of the enamel margin, while in Group 2 this step was omitted. A pain measurement  was performed at a first control, a week before the restoration placement. The patients, subjected to tactile-thermal stimuli, were asked to rate the experienced sensitivity on a visual analog scale(0=no pain, 10=excruciating pain). Only patients scoring low (1-4) were included in the study. Post-operative sensitivity, marginal discoloration and integrity, secondary caries, tooth vitality, retention and fracture were evaluated 1 and 7 days, 1, 6 , 12 months after the restoration placement.

Results: For all the teeth showed sensitivity before restoration, such phenomenon disappeared after restoration. All the restored  teeth remained vital; no secondary caries or fracture was observed; all the restoration were retained and maintained satisfactory marginal integrity over the 1-year period.

Conclusions: Class V restorations performed with G-aenial Bond in combination with the proprietary           G-aenial Universal Flo exhibited a satisfactory clinical behavior over 1-year period, regardless of the preliminary  selective phosphoric acid etching .
