Evaluation of a New Bioactive Material Versus a Fluoride-Releasing Hybrid Restorative Material in Cervical Lesions

Cairo University30 enrolled

Overview

* This study will be conducted to evaluate and compare the clinical performance of fluoride, calcium, and phosphate-releasing new bioactive material versus a fluoride-releasing hybrid restorative material in cervical lesions for one-year follow-up. * The clinical evaluation will be done using modified USPHS criteria at baseline,3,6,9 and 12 months.

two groups of 30 patients will receive cervical restorations by using calcium and phosphate releasing hybrid restorative material (Activa™ Presto, Pulpdent®, USA), or a fluoride-releasing hybrid restorative material (Giomer, Shofu, Japan). Then these restorations will be evaluated at baseline, 3 months, 6 months, 9 months, and 12 months according to modified USPHS criteria in terms of marginal adaptation, Marginal discoloration, recurrent caries, retention, surface texture, and Post-operative sensitivity. * Examination and selection of all patients will be done according to inclusion and exclusion criteria. * A class v cavity will be prepared after local anesthesia has been given as required. Rubber dam isolation followed by the placement of restorative material according to the randomization sequence. * For the intervention: selective etching to enamel and universal bond agent to all the cavity will be applied first, followed by filling of the cavity with fluoride, calcium, and phosphate-releasing new bioactive material (Activa™ Presto, Pulpdent®, USA) using a 19-gauge applicator tip on the syringe and light-curing for 20 seconds between each 2mm layer. * For the control group: selective etching to enamel and universal bond agent to all the cavity will be applied first, followed by filling of the cavity with fluoride-releasing hybrid restorative material (Giomer, Shofu, Japan) and will be light polymerized using a light-emitting diode (LED) light-curing unit for 10 seconds between each 2mm layer.

cervical restorationPROCEDURE

A class v cavity will be prepared after local anesthesia has been given as required. Rubber dam isolation will be done. Selective enamel etching and a universal adhesive agent (Beautibond, Shofu, Japan) will be applied over all the cavity surfaces. Followed by, placement of restorative material according to the randomization sequence. Finally, restoration finishing and polishing will be done.

Outcomes

Primary Outcomes

Marginal adaptation

The restoration will be clinically assessed by visual inspection and explorer. Restorations will be given a score using modified USPHS criteria: Alfa: Closely adapted, no visible crevice Bravo: Visible crevice, the explorer will penetrate Charlie: Crevice in which dentin is exposed

Time frame: one year

Secondary Outcomes

Marginal Discoloration

Clinical evaluation by visual inspection and mirror if needed using modified USPHS criteria. Restorations will be given the score: Alfa if No discoloration Bravo if Non penetrating marginal discoloration which can be polished away Charlie if Discoloration with penetration in pulpal direction.

Time frame: one year

Retention

Clinical evaluation by visual inspection and explorer. Restorations will be given a score according to modified USPHS criteria : Alfa if restoration is retained and there is no loss of restoration. Charlie if loss of restoration.

Time frame: one year

Secondary caries

Clinical evaluation by visual inspection and explorer. Restorations will be given a score according to modified USPHS criteria: Alfa if no recurrent caries is detected, charlie if recurrent caries is detected. .

Time frame: one year

surface texture

Clinical evaluation by visual inspection and explorer. Restorations will be given a score according to modified USPHS criteria: Alfa if restoration is enamel-like surface Bravo if Surface rougher than enamel, clinically acceptable Charlie if Surface is unacceptably rough.

Time frame: one year

postoperative sensitivity

Verbal evaluation by asking the patient. Restorations will be given a score according to modified USPHS criteria: Alfa if not present Bravo if sensitive but diminishing in intensity Charlie if constant sensitivity not diminishing.
