Abstract
Objective: This study aimed to assess the clinical and radiographic success for photo-activated oral disinfection (PAD) and calcium hydroxide in indirect pulp treatment (IPT) of young permanent molars. Background: Different materials were used in the treatment of deeplydecayed vital teeth. For many years, the gold standard for indirectpulp capping procedures was Calcium hydroxide. Nevertheless, thedisadvantages reported with its use has led to its replacement withother materials. Methods: Thirty-two vital first permanent molars with deep caries were treated by (IPT) with either photo-activated oral disinfection (group 1) or calcium hydroxide (group 2). Clinical and radiographic success as well asnewly formed dentin thickness were evaluated regularly at 2, 6and 9 months. Results: The success for both groups was 100% clinically and radiographically at all follow up periods. Regarding the mean thickness of newly formed dentin for both groups at different follow up periods, there was no statistical significant difference between both groups at 2, 6 and 9 months, with P values = 0.825, 0.146 and 0.280 respectively. Conclusion: Photo-activated oral disinfection and calcium hydroxide reported similar effect in deep caries treatment and hence photo-activated oral disinfection can be used as a replacement to calcium hydroxide in IPT
