Clinical Trial Summary

In patients with occlusal caries in posterior teeth, does the use of recently introduced non coated glass ionomer provide better clinical performance compared to conventional glass ionomer with surface coating?

-Primary objective: To evaluate clinical performance of different types of restorations (Ketac molar with coating and Ketac Universal Aplicap 3M without coating) in occlusal caries in posterior teeth.


Clinical Trial Description

The study will be conducted in Conservative Dentistry Department, Faculty of Dentistry, Cairo University; The operator in charge will be Mahmoud Magdy Eldamanhory

Patients will be selected from the outpatient clinic of the department Conservative Dentistry Department, Faculty of Dentistry, Cairo University

- Local anesthesia will be applied to patients complaining about pain or sensitivity to prevent discomfort during restorative procedures.

- Conservative cavity design will be used according to the principals of minimal invasive dentistry.

- All the cavities will be performed by the main author using #57 straight plain carbide fissure bur held in high speed contra-angled hand piece with water cooling system.

- All internal line angles will be slightly rounded.

- Each bur will be discarded after 5 preparations

- If deep caries will be found, it will be removed with large round bur at low speed and a thin layer of calcium hydroxide will be placed on the deep portion of the cavity.

- Isolation will be maintained by using Rubber Dam.

- The dentin and enamel of cavities will be conditioned with 20% polyacrylic acid for 20 seconds (Cavity Conditioner, GC), washed, and briefly dried.

- The restorations will inject into the cavity.

- After the passage of the manufacturer's recommended setting time of 2.5 minutes, the restoration will be trimmed and polished wet using high-speed fine diamonds.

In control group ketac molar with coating:

-After the restoration will briefly dry, Ketac Coat will be applied and photocured for 20 seconds using a photo-curing light.

In study group " Ketac Universal Aplicap 3M without coating":

-The newest addition to glass ionomer family, Ketac Universal Aplicap glass ionomer restorative is a self-cure, one-step placement material designed to help to finish faster. There's no need for conditioning, coating or light-curing steps. ;
