Abstract

Aim: To study the effectiveness of photo activated disinfection (PAD) Disinfection Versus Calcium Hydroxide Disinfection in Regeneration of Immature Infected Teeth. Material and Methods:30 patients with immature, single rooted teeth appearing with or without signs and/or symptoms of periapical pathology were involved in the study. Cases were classified into three groups according to the disinfection protocol, ten patients each group (n=10). Group I: Calcium hydroxide (Ca (OH)) was injected in the canal after drying the canal with sterile paper points. Group II: Photosensitizers (Azulenocyanine) was inserted in the canals and agitated in the canal, then activated with diode laser 940 nm used in cycles 4 x 2mm/sec for disinfection of canal. Group III: Photosensitizers (Azulenocyanine) was inserted in the canals and agitated in the canal, then activated with diode laser 940 nm used in cycles 4 x 2mm/sec for disinfection of canal then calcium hydroxide (Ca (OH)) is injected in the canal after drying the canal with sterile paper points. Results: Overall results of our study, there was a significant difference (p>0.05) between the three groups, where group III “calcium hydroxide and diode laser” showed higher significant values than the other two groups. Conclusion: PAD can be used as an adjunctive procedure in disinfection of immature necrotic teeth.
