| Abstract | Introduction: Horizontal root fracture (HRF) is a complex traumatic dental injury that affects the pulp, dentin, cementum, and periodontal ligament. This retrospective cohort study evaluated treatment outcomes in permanent teeth with HRF. Methods: We analyzed clinical and radiographic data from a dental trauma center (2006-2022). Permanent teeth with HRF with a follow up of ≥12 weeks were considered for outcome assessment (defined as clinical normalcy and radiographic healing at the fracture line). Prognostic factors were identified through multivariable logistic regression analyses (P value ≤ .05). Results: 125 teeth from 103 patients were included. After a median follow-up of 79 weeks, the overall favorable outcome was 92%. This includes teeth that received emergency splinting/repositioning at baseline (62.2%) and those that received subsequent endodontic intervention for the coronal fragment (baseline: 85%; subsequent follow-ups: 91.8%). Being male and incomplete root development were both significantly associated with a better outcome of splinting/repositioning (OR = 2.58; 95% CI, 1.06-6.24 and OR = 4.37; 95% CI, 1.16-16.41, respectively) and a reduced likelihood of requiring endodontic treatment (OR = 0.44; 95% CI, 0.20-0.96 and OR = 0.24; 95% CI, 0.08-0.76, respectively). Treatment delays surpassing one week were significantly associated with an increased likelihood of requiring endodontic treatment compared to timely presentations within 24 hours (OR = 3.06; 95% CI, 1.07-8.77; P value < .05). Conclusion: With timely diagnosis and treatment, and close monitoring, HRF cases can achieve a 92% favorable outcome. Male sex and incomplete root development correlate with improved baseline outcomes and a reduced need for endodontic treatment. Conversely, delayed presentation increases the likelihood of requiring endodontic intervention. |
