“Dentine Topographic Features and Shear Bond Strength of Resin Modified Glass Ionomer Adhesive Following Mechanical and Chemomechanical Caries Removal in Primary Teeth” (In-Vitro Study)

Abstract

Dental caries is one of the most prevalent dental problems worldwide and has an impact on Oral health-related quality of life (OHRQoL). So, its management is considered as the main issue in oral healthcare especially in pediatric dentistry. There are different methods of dental caries management, one of them is the conventional rotary method. It has many disadvantages like pain sensation, vibration and need of local anesthesia. During the last decades, the concept of minimally invasive dentistry (MID) had been introduced to overcome the disadvantages of the conventional drilling method. CMCR is one of MID. It has several advantages as comfort, ease of use clinically and remove only the diseased tissue. Furthermore, it is painless, need minimal pressure for optimal usage without vibration during the treatment. CMCR is classified into sodium hypochlorite based (NaOCl) CMCR as Cariemove and enzyme based one as Papacarie. Regarding to different studies, the different caries removal methods have an effect on dentine topography and the shear bond strength of resin modified glass ionomer adhesives (RMGI) as well. Few studies evaluated the effect of CMCR method in comparison to conventional drilling method of caries removal concerning the changes in the dentin topography and the shear bond strength of adhesive restorative materials. Aim of our study was to evaluate the dentin topography under scanning electron microscope (SEM) after removal of caries with two different caries removal methods (Cariemove CMCR and conventional drilling method) and examine the shear bond strength of resin modified glass ionomer adhesive (RMGI) to caries affected dentin following the two different methods of caries removal.
