Background: Complicated crown-root fractures are a type of tooth fracture that involves the enamel, dentin, and cementum and accompanied by pulp exposure. The treatment of a complicated crown-root fracture is always challenging due to the difficulties in achieving a hermetic seal and a stable restoration with a fracture level close to the crestale bone level. This study aimed to evaluate and compare the efficacy of single-visit and multi-visit approaches for fragment reattachment in complicated crown-root fractures of anterior teeth.
Methods: Two cohort consist of 10 adolescent patients in each group at both genders, who suffered from permanent anterior tooth complicated crown-root fracture were included. Fragment reattachment with root canal treatment was performed with either single or multiple-visit approach. Single visit fragment attachement combined with root cannel therapy was conducted in single-visit approach group immediately after injury. Fragment attachment, root cananel therapy and post resoration were performed during three times ' clinical visit in multi-visit approach group.
Results: All the patients in both groups achieved satisfactory aesthetic results one year after fragment reattachment. Patients who underwent a multi-visit approach had a significantly shorter operative duration, less intra-operative pain and fatigue, slightly better periodontal health at an early stage, and a decreased incidence of temporomandibular joint disorders compared to those who underwent a single-visit approach. However, multiple visits approach may increase the risk of fragment detachment postoperatively.
Conclusion: Fragment reattachment a reliable but temporary technique for adolescent patients who have suffered from complicated crown-root fractures. Multi-visit approach showed similar effecacy to single-visit approach but with slightly less complications. The choose of these two merhos should depend on the specific patient situation and patient compliance.
Trial Registration: This prospective cohort study was retrospectively registered in Chinese Clinical Trial Registry (ChiCTR2300076811) on 19/10/2023.

Objective: This study aimed to evaluate the prognosis of root canal treatment (RCT) in dogs with complicated crown-root fractures (CCRFs) of the maxillary fourth premolar (PM4), focusing on the impact of periodontal probing depth (PPD) and furcation involvement on treatment outcomes.
Methods: The study analyzed 122 PM4 teeth affected by CCRF in dogs. The primary outcomes were the success rates of RCT, measured against PPD, and the degree of furcation involvement (stages F0, F1, and F2).

Article Synopsis
- Complicated crown-root fractures are significant dental injuries affecting multiple tooth structures and occur infrequently in permanent teeth.
- A 14-year-old male sustained this type of fracture in a motor vehicle accident, leading to challenges in treatment due to the fracture's location.
- A multidisciplinary team opted for root canal treatment and gingivectomy to restore the tooth, emphasizing the importance of supracrestal tissue attachment for periodontal health and the necessity of regular follow-ups for monitoring.

Article Synopsis
- Maxillary third molar extractions often lead to complications like oroantral communications, making it hard for inexperienced clinicians to evaluate risks and difficulty levels.
- A case study using advanced imaging techniques explored variables affecting extraction outcomes, including bone volume, quality, and the newly defined "tegmen bone."
- The findings suggest that predictive analysis can enhance decision-making in complex tooth extractions by focusing on anatomical factors specific to each case.
