Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Clinical Procedures The materials that will be used to restore cervical lesions in this study are self-adhesive bulk-fill composite (Surefil One, Dentsply Sirona) and Nanohybrid composite. Materials will be used according to manufacturer's instructions. Class V cavities will be prepared, restored, finished, and polished. Each patient will at least have one tooth restored by Surefil One and one tooth at least will be restored by conventional nano-hybrid composite.
For each patient, shade selection will be performed and accordingly the suitable shade of the composite will be selected before the start of any procedure using a dental shade guide. Local anesthesia will be given at the operation site and cervical cavities on the buccal surfaces will be prepared using 330 bur and finished using a red-coded stone to finish enamel margins and to create a bevel at the incisal margin of the cavity. Rubber dam will be placed on teeth restored to isolate the operative field before the initiation of the restorative process and a stopwatch will be used to record the time taken to place both restorations; starting from their application inside the cavity and the recording will be terminated right after finishing the restorative procedures.
Intervention At least one tooth in each patient will be restored with Surefil One capsule, following manufacturer's instructions, without any prior adhesive preparations. Capsule will be placed in the automatic mixer and mixed for six to eight seconds. Cleaning of the cavity will be achieved using an air-water spray leaving a moist cavity surface. The activated capsule will be attached to the applicator gun and the material is inserted inside the cavity at the deepest portion and gradually withdrawn allowing slight overfilling. Once the restorative material is applied and excess is removed using a hand instrument, restoration will be light cured using a LED Light Curing unit. The tip of the light unit will be put in contact with the glass slide during the light-curing process. The distance between the light source and the restoration will be standardized using a standard slide to ensure fixed curing distance. Rubber dam will be removed subsequently, and the finishing process of the material will be initiated using discs and finishing stones while the restoration is moist. A single step polishing protocol is followed consequently.
Comparator In the same patient, at least one tooth will be restored by conventional nano-hybrid composite. Etching of the enamel margins by 37% phosphoric acid will be done, rinsing with water after 20 seconds afterwards, drying using air blowing, followed by active application of two layers of Prime \& Bond universal adhesive (Dentsply Sirona, Konstanz, Germany) using a micro-brush to the cavity, a waiting period of 15 seconds to allow the optimum penetration of the adhesive and curing for 20 seconds. Restorative material will be added incrementally, an increment of 2 mm thickness will be added, and light cured. Finishing of restorations will be done simultaneously after rubber dam removal using finishing discs and finishing stones. Restorations will be subsequently polished using a single step protocol of polishing.
Evaluation Procedures Cervical restorations will be inspected at baseline and after six months of restoration placement. The principal investigator will make sure to call each patient prior to their recall appointment to make sure that they show up exactly on the date and at the time of their follow up appointments. Restorations will be examined by two trained external blinded evaluators immediately after placing of restorations and their subsequent finishing and polishing without knowing which material was used in each cavity.
The USPHS criteria are selected and modified to suit the criteria chosen for the restoration evaluation. Evaluation instruments are dental mirrors, explorers, and intraoral photographs. Radiographs will only be taken if clinically indicated, for example caries diagnosis or pain experience. Adverse events regarding product safety will be recorded. Color match, surface roughness, marginal discoloration, marginal adaptation, retention, and the presence of secondary caries around restorations will be evaluated at baseline and after six months as a primary outcome. In addition, patient's satisfaction with the restoration will be measured immediately post-operative using Visual Analogue Scale (VAS) scores and the time elapsed from the start of isolation till finishing and polishing of the interventional restoration will be measured and compared to the time elapsed when restoring using a conventional composite. All observations will be recorded.
