Long-Term Outcomes of Cervical Pulpotomy Using ZOE in Immature Permanent Teeth: A Retrospective Cohort Study

Cervical pulpotomy may preserve pulp vitality and support continued root development in immature permanent teeth with thin dentinal walls and wide apices. This 5-year retrospective cohort study evaluated the outcomes of zinc oxide eugenol (ZOE) cervical pulpotomy in traumatized anterior and carious posterior teeth treated at two academic centres. A total of 108 patients (192 teeth; 84 anterior and 108 posterior) were included, with a mean age of 8.86 ± 1.36 years and a mean follow-up period of 63.08 ± 3.60 months. The overall success rate was 91.7%. No statistically significant differences were observed between anterior and posterior teeth (94% vs. 89.8%; OR = 1.79; 95% CI: 0.60-5.37; p = 0.298) or between maxillary and mandibular teeth (93.3% vs. 88.9%; OR = 1.75; 95% CI: 0.63-4.89; p = 0.286). In conclusion, vital immature permanent teeth can be successfully treated with ZOE cervical pulpotomy.
