In this study, Class V carious lesions will be restored using two different restorative materials either Resin modified glass ionomer or Giomer based injectable resin composite. Patients will be assessed for medical and dental histories first. Then an examination of the patients will be done using visual inspection by using a dental mirror and probe. Eligible patients according to inclusion and exclusion criteria will be informed about all procedures with follow up time if they accept. Their signature on written informed consents will be obtained. Eligible participants will be randomly divided into two groups according to the type of restoration they will be received.The first group (A) (Intervention): Giomer based injectable resin composite (Beautifil Flow plus X F03, SHOFU, USA): The material will be applied according to manufacturer instructions. The second group (B) (comparator): Resin modified glass ionomer (Fuji II LC, GC): The material will be applied according to manufacturer instructions.The restorations will be evaluated at baseline and regular recalls of 3 months, 6 months, 12 months and 18 months, using modified United States Public Health Service criteria (USPHS) for the following characteristics: retention, anatomical form, marginal adaptation, marginal staining, surface texture, and secondary caries . The restorations will be evaluated with the aid of a dental explorer and an intraoral mirror and visual inspection. The restorations will be scored as follows: Alfa represents the ideal clinical situation, Bravo will be clinically acceptable, and Charlie represents a clinically unacceptable situation.
