About

The object of this study is to compare the effect of Calcium Hydroxide and Di-antibiotic paste as intracanal disinfectants in the 1st visit of revascularization of necrotic immature permanent anterior teeth.

Full description

Dental trauma is common in children and it is the main cause of loss of pulp vitality in immature permanent anterior teeth with prevalence rate of 11% and about of 27% of traumatized anterior teeth are left untreated. Dentists face many challenges during the treatment of infected immature permanent teeth. This is mainly due to the thin dentinal walls of the root and blunderbuss apices that make these teeth susceptible to fracture during and after treatment. Traditionally, Calcium Hydroxide apexification has been the only method for managing these cases.. however, it was found that this technique caused additional reduction in root strength due to the long-term application of Calcium Hydroxide which may end in fracture of the tooth. The time needed for complete apexification using Calcium Hydroxide was reported to be variable ranging from 5 to 20 months, with failure rate 0f 30% . Therefore, this technique is no longer recommended for the treatment of such cases. A recently proposed technique for the treatment of immature necrotic permanent teeth is revascularization regenerative endodontic therapy (RET). It is a biologically based technique that allow the continuation of root development and thickening of dentinal walls. This is achieved through proper disinfection o the root canal system, creation of scaffold and perfect coronal seal. For proper disinfection of the root canal system, antibiotic paste was applied as intracanal dressing for 2-3 weeks. However, the recent recommendations by the European society of Endodontology advices the use of Calcium Hydroxide as intracanal medication instead of intracanal antibiotics. This is because of some concerns regarding the use of antibiotics which include: cytotoxicity to stem cells needed for the revascularization process, risk of antibiotic resistance and the risk of sensitization. Calcium Hydroxide on the other hand is widely used as intracanal disinfectant and some studies were found supporting its use in the revascularization technique, [9, 10]. However, the data available is not sufficient regarding the effectiveness of Calcium Hydroxide in revascularization of necrotic pulp. Besides, more trials are needed to evaluate the clinical effectiveness of RET in management of immature necrotic permanent teeth as the evidence of using this technique is still weak.
