Brief summary

This clinical trial will be conducted to compare the clinical performance of the thermo-viscous preheated bulk fill composite in the management of carious lesions in posterior teeth in adult patients over 12 months.

Interventions

OTHERthermoviscous bulkfill composite (Viscalor)

a relatively new product of composite resin which is transformed from high viscosity to low viscosity by the action of head produced by a heating device.

Inclusion criteria

* Have at least two molars supported permanent dentition free of any clinically significant occlusal interference and require posterior restoration and fulfilled the inclusion criteria, patients will be informed about the study and will be given an informed consent. * The two studied materials restorations should be used in approximately the same sized lesions or within the same extensions. * The patient will be reimbursed for attending for the clinical evaluation(s) of their restorations. * Be a regular dental attender who agree to return for assessments.

Exclusion criteria

* There is history of any adverse reaction to clinical materials of the type to be used in the study. * There was evidence of occlusal parafunction and/or pathological tooth wear. * Patients whose history revealed parafunctional habits or use of medications that potentially could cause hyposalivation.
