Abstract
BackgroundCalcium hydroxide is the most commonly used material in indirect pulp treatment (IPT). However, its drawbacks required its replacement by other materials.AimThis study aims to estimate clinically and radiographically the success of indirect pulp treatment of young permanent molars with either photo-activated oral disinfection (PAD) or calcium hydroxide.DesignThis Randomized Controlled Pilot Trial included 32 vital first permanent molars with deep caries that were treated by indirect pulp treatment with either PAD (group 1) or calcium hydroxide (group 2). Clinical and radiographic success in addition to newly-formed dentin thickness were evaluated regularly at 2, 6, 9, and 12 months.ResultsThe 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 statistically significant difference between both groups at 2, 6, 9, and 12 months, with P values = 0.825, 0.146, 0.280, and 0.400, respectively.ConclusionsThe clinical and radiographic success for indirect pulp treatment of young permanent molars with both PAD and calcium hydroxide were comparable.
Highlights
Calcium hydroxide is the most commonly used material in indirect pulp treatment (IPT)
Children were divided into two groups: Group 1 was treated using photo-activated oral disinfection (PAD) with a mean age 9.94 years and Group 2 was treated using calcium hydroxide with a mean age 9.75 years
The systematic review of Bergenholtz et al.[10] showed that there are significant gaps in our knowledge concerning the treatment of the vital pulp with deep carious lesions and this study was carried out to compare two different methods for indirect pulp treatment
Summary
Calcium hydroxide is the most commonly used material in indirect pulp treatment (IPT). Indirect pulp treatment is a procedure, in which pulp exposure is prevented by preserving the carious dentin bordering the pulp and sealing the pulp with a biocompatible material.[1] Calcium hydroxide is the gold standard for pulp capping It maintains the pulp vital, allows reparative dentin formation, shelters the pulp against harmful stimuli and has antimicrobial effect.[2] many disadvantages were reported with its use over time including poor seal, lack of chemical and mechanical adhesion, poor strength, long-term solubility, enhanced disintegration after acid etching, and tunnel defects in the dentin bridge.[3] The operative practice is to excavate the soft dentin to eradicate infected tissue; it is difficult to eliminate all the microorganisms because few will remain even though the soft dentin was removed.[4]. For more conservative and effective treatment, disinfection instead of complete caries removal has been encouraged.[6]
