About

This study will be conducted to evaluate the clinical assessment of an alkasite based resin composite restorative material compared to resin modified glass ionomer based restorative material in class V cavities of anterior teeth over 12 months follow up using modified USPHS criteria.

In patients with anterior cervical (class V) carious lesions, will the novel alkasite-based restorative material show similar clinical assessment as resin modified glass ionomer over a one year follow up period?

Full description

Dental caries is a common chronic infectious illness caused by cariogenic bacteria that metabolize sugars to generate acid, which gradually demineralizes tooth structure. Dental caries is a major healthcare problem as it is the most prevalent disease worldwide. Low socioeconomic level groups are more likely to be affected by the disease and during the past thirty years, its prevalence has not considerably decreased despite being completely preventable.

Non-invasive methods (such as sealing, biofilm removal, and remineralization) should be used to treat existing early caries rather than removing the dental tissue. Cavitated lesions should be arrested or managed using a minimally invasive method, such as conservative cavity designs, and repairing defective restoration rather than replacing it.

Ion-releasing restorations are recognized for their biocompatibility with surrounding tissues and their fluoride-releasing capabilities, which are thought to help prevent caries by creating an oral environment that prevents the demineralization of surrounding hard tooth tissue.

Resin modified glass ionomer (RMGI) is utilized for a variety of purposes, as luting agents, liners/bases, and restorative materials. The RMGI is more aesthetically pleasing than the conventional glass ionomer while maintaining the clinical benefits of the former, such as the release of fluoride, recharging capabilities, prevention of decalcification of hard tooth tissue, inhibition of bacterial acid metabolism, and ease of clinical operation.

A novel family of bioactive "alkasite" restorative materials, essentially a subgroup of composite resin, represents a new era of restorative dentistry. This material is available in a capsulated form using a unique adhesive system. An alkaline filler that has the ability to release ions that neutralize acids is used in this novel material. It is stated that this substance can neutralize bacterial acids by releasing hydroxide ions and remineralize hard dental tissues by releasing calcium and fluoride. The material's release of ions may be crucial in neutralizing the effects of cariogenic bacteria, thus guarding against tooth caries.

The author conducted a study to evaluate the performance of two different restorative materials in patients with class V carious lesion in upper anterior teeth where the esthetic appearances is highly recommended.

Alkasite-Based Resin Composite Restorative Material (Bioactive Material)

Experimental group

Description:

Alkasite material releases hydroxyl ions, calcium, fluoride, and phosphate ions which explains its caries-prevention mechanisms. Many researches indicate that this alkasite material neutralizes acids and prevents enamel and dentin demineralization when exposed to lactic acid for an extended length of time together with the added advantageous of maximum properties and esthetics of resin composite

Treatment:

Other: alkasite based restorative material

Resin Modified Glass Ionomer Restorative Material

Active Comparator group

Description:

Resin-modified glass-ionomers have mainly the same clinical applications as conventional glass-ionomers. Their biocompatibility and ability to release fluoride are two of their advantages. In addition, it has advantages over traditional glass ionomer in terms of stronger features, better aesthetics, earlier finishing, and longer working time. They are considered the gold standard in restoring cervical carious lesions of anterior teeth over GI due to their added benefit of higher esthetics.
