About this study
Official title: Comparison of Regenerative Endodontic Procedures Using Periapical Bleeding Induction, L-PRF, and I-PRF in Mature Teeth With Periapical Lesions: A Randomized Controlled Clinical Trial
This study investigates a biological approach that allows infected and necrotic teeth to heal themselves instead of being treated with traditional root canal therapy. Traditional root canal treatment involves cleaning the infected tissue inside the tooth and sealing it with a filling material, whereas regenerative endodontic treatment is a novel approach that enables the tooth to repair itself. This treatment method involves inducing bleeding in the root area or applying special blood derivatives (PRF types) to accumulate healing-supporting cells and growth factors. The aim of the study is to compare the effects of different biological treatment methods on the healing process, postoperative pain, and tooth discoloration. The results may help develop more effective and aesthetically successful treatment options in the future.
Read the detailed description
This study investigates the effectiveness of regenerative endodontic procedures in the treatment of necrotic and infected teeth. Traditional root canal treatment involves the complete removal of infected tissue from inside the tooth and sealing the root canal with a biocompatible filling material. However, this method does not restore the tooth's natural vitality or protective mechanisms. Additionally, it may increase tooth fragility and lead to discoloration over time.
Regenerative endodontic treatment is a biological approach that promotes the self-healing of the tooth. This method applies tissue engineering principles to stimulate the formation of new tissue within the root canal. During the treatment process, either bleeding is induced at the root tip or special platelet-rich fibrin (PRF) derivatives are applied to facilitate the accumulation of stem cells, growth factors, and immune-boosting components that support healing.
This study compares the effects of different regenerative treatment methods (bleeding induction, L-PRF, and I-PRF applications) on lesion healing, postoperative pain, and tooth discoloration. By determining the most effective method for teeth with completed root development and apical lesions, the study aims to establish an optimal treatment protocol for clinical practice. The findings will contribute to the development of treatment options that preserve the natural structure of the tooth, enhance aesthetics, and improve patient comfort and long-term treatment success.

What is being measured
The primary outcome is the main question the study is designed to answer.
Radiographic Assessment of Lesion Healing at 6 Months
Lesion healing will be evaluated using periapical radiographs with the parallel technique, and the Periapical Index (PAI) will be used for the assessment of lesion healing.
Measured: Baseline and 6 months
Change in Pain Level at 24 Hours, 72 Hours, and 1 Week Post-Treatment
Pain levels will be assessed using the Numerical Rating Scale (NRS), ranging from 0 (no pain) to 100 (worst pain), measured at 24 hours, 72 hours, and 1 week post-procedure.
Measured: Post-Treatment at 24 Hours, 72 Hours, and 1 Week
Assessment of Tooth Discoloration at 6 Months
Tooth discoloration will be evaluated using a spectrophotometer based on the CIELab system, and teeth with a ΔE value greater than 3 will be considered discolored.
Measured: Baseline and 6 months
