Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to compare the effect of high intensity light cure (2200 mw/cm2) for 1 second with low intensity light cure (1200 mw/cm2) for 20 seconds on the clinical performance of bulk fill resin composite restorations in compound Class II cavities of posterior teeth

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The prepared cavities will be conditioned with 35% phosphoric acid gel for15 seconds, then will be rinsed and dried with compressed air. Then application of universal adhesive system to all cavity with bond brush then light cured for 10 seconds using LED light curing unit (1200 mw/cm2). Extra-Fill bulk fill resin composite will be applied in onebulk increment and will be light polymerized for 1 second using (LED) light curing unit (2200 mw/cm2).for intervention group Extra-Fill bulk fill resin composite will be applied in one bulk increment and will be light polymerized for 20 seconds using (LED) light curing unit (1200 mw/cm2) fot control group

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High intensity light cure

High intensity light curing (2200 mw/cm2)To achieve increased power and a wider spectrum for short exposure time (1 second) to overcome resin composite restoration techniques sensitivity and shorten the clinical procedure

Group Type EXPERIMENTAL

High intensity light cure

Intervention Type DEVICE

Bulk fill resin composite restoration cured with high intensity light curing (2200 mw/cm2)To achieve increased power and a wider spectrum for short exposure time (1 second) to overcome resin composite restoration techniques sensitivity and shorten the clinical procedure

Low intensity light cure

Conventional light curing (1200 mw/cm2) for long exposure time (20 seconds) to achieve the slower rate of conversion allowing for a better flow of the material, which decreases contraction stress in the filling material

Group Type ACTIVE_COMPARATOR

High intensity light cure

Intervention Type DEVICE

Bulk fill resin composite restoration cured with high intensity light curing (2200 mw/cm2)To achieve increased power and a wider spectrum for short exposure time (1 second) to overcome resin composite restoration techniques sensitivity and shorten the clinical procedure
