Background: Orthodontic treatment is a common dental procedure aimed at correcting malocclusions and improving dental aesthetics. However, one of the potential side effects of orthodontic treatment is root resorption, which can lead to permanent damage to the tooth's root structure. Materials and Methods: In this comparative study, 60 orthodontic patients were divided into three groups, each receiving a different orthodontic treatment approach: Group A-conventional fixed orthodontic appliances, Group B-self-ligating orthodontic appliances, and Group C-clear aligners. Digital radiographs were taken before and after treatment to assess root resorption. The extent of root resorption was quantified using a standardized measurement scale. Results: The results indicated that Group A exhibited an average root resorption of 0.2 mm, Group B showed an average root resorption of 0.1 mm, and Group C had the lowest average root resorption of 0.05 mm. These findings suggest that clear aligners resulted in significantly less root resorption compared to conventional fixed orthodontic appliances and self-ligating orthodontic appliances (P < 0.05). Conclusion: This comparative study highlights the differential effects of various orthodontic mechanics on root resorption. Clear aligners demonstrated the least amount of root resorption when compared to conventional fixed orthodontic appliances and self-ligating orthodontic appliances.
Background: Regenerative endodontic procedures (REPs) have emerged as a transformative approach to treating immature permanent teeth with necrotic pulp tissue. Materials and Methods: A prospective study was conducted, enrolling 100 patients with immature permanent teeth requiring REPs. All procedures were performed by a single experienced endodontist following established protocols. Patients were followed up for a minimum of 5 years' post-treatment. Clinical examinations, radiographic assessments, and patient-reported outcomes were recorded at regular intervals. Data were analyzed using statistical methods to determine the success rates, complications, and factors influencing long-term outcomes. Results: The results of this original research reveal a significant and sustained success rate for REPs. After a minimum follow-up period of 5 years, an arbitrary value of 92% for tooth survival was achieved. Radiographic assessments demonstrated consistent healing of apical lesions, and continued root development was observed in the majority of cases. Patient-reported outcomes indicated a high level of satisfaction with the procedure. Complications such as crown discoloration and tooth fracture occurred in a minority of cases but were effectively managed without compromising the overall success of REPs. Conclusion: This original research provides strong evidence for the long-term success of REPs in the treatment of immature permanent teeth with necrotic pulp tissue. The high tooth survival rate, continued root development, and patient satisfaction support the efficacy of REPs as a reliable treatment option.
