“Assessment of Efficacy of Photoactivated Disinfection versus Calcium Hydroxide Disinfection in Regeneration of Immature Infected Teeth” (A comparative in vivo study)

Abstract

The aim of our study was to compare the effectiveness of photoactivated disinfection versus calcium hydroxide disinfection in the regeneration of immature necrotic anterior permanent teeth. The clinical study included 30 patients of necrotic immature anterior teeth. Cases were divided equally into 3 groups. Group I using calcium hydroxide, Group II using PAD and group III using both calcium hydroxide and PAD as disinfection methods. All cases were treated using PAD or calcium hydroxide paste for 2-4 weeks, followed by induction of bleeding into the clean disinfected canals, which were then sealed by white MTA coronal plug then evaluated clinically and radiographically in the follow up periods up to 12 months. Clinical evaluation included history taking and clinical examination regarding presence or absence of periapical pain, swelling or sinus tract. Clinical follow up showed that all cases were asymptomatic, functional, and irresponsive to hot test throughout the follow up period. Some cases experienced mild pain or discomfort for few days postoperatively.
