ABSTRACT


Aim: This Study Was Conducted To Evaluate And Compare The Thickness Of Calcificbridge Formed By Indirect Pulp Capping Using Light Activated Calcium Silicate Versus Light Activated Calcium Hydroxide, Immediately After Restoration And One Year Later Using Digital Radiography.Methodology: 30 Participants Were Recruited In This Study For Having 60 Molars With Deep Occlusal Carious Lesions. Molars Of Each Patient Were Randomly Divided Into Two Groups Treated With Partial Caries Removal Technique The Firstgroup Represented Teeth Treated With Application Of Light Activated Calcium Silicate (TheraCal) Prior To Finalpermanent Resin Composite Restoration, The Second Group (comparator Group) Represented Teeth Treated With Light Activated Calcium Hydroxide. Radiographic Images Were Obtained And Radiographic Dentin Bridge Thicknesses Were Evaluated Using Digora For Windows Computer Software At Baseline Immediately After Restoration And After One Year.

Results: The Formed Dentin Bridge Thickness Was Thicker In The Calcium Hydroxide Group Than Calcium Silicate Group (0.24%mm And 0.16%mm Respectively) And The Percentage Of Change In Dentin Bridge Thickness After One Year Was Thicker In Calcium Hydroxide Group Than Calcium Silicate (TheraCal) Group (24% And 16.26% Respectively).

Conclusions: Calcium Hydroxide Is Still Effective As A Pulp Capping Material Compared To Resin Modified Calcium Silicate
