The effect of marsupialization of large cystic lesions of the jaws on pulp vitality

Abstract

There is a paucity of studies evaluating the preservation and recovery vitality of teeth associated with cystic lesions in the jaws.The purpose of the present study was to evaluate whether the use of the marsupialization treatment method in the large cystic lesions of the jaws associated within involved teeth would save the pulp vitality.It was a cohort study of patients treated at the Department of Oral and Maxillofacial Surgery from April 2019 to April 2023. Patients with primary cystic lesions associated teeth, with a cyst diameter of >3.4 cm, along with dental root resorption of less than half the root length, and treated by marsupialization were included. Patient age, gender, location, associated teeth, size, management, dental pulp vitality before and after marsupialization, and the duration of treatment were evaluated. Pulp vitality of involved teeth was assessed with electrical pulp tester.It was the treatment method.The primary outcome variable was the recovery or preservation of pulp vitality.The study variables were demographic, clinical features of the cysts, clinical features of associated teeth, and treatment method.Categorical data were presented in mean with standard deviation, and set the level of statistical significance at p < 0.05.The sample included 73 patients with large cystic lesions; 47 (64.4%) were male and 26 (35.6%) were female. The age range was 9 to 68 years (mean ± standard deviation, 22.4 ± 4). The 73 patients had 305 teeth associated with large cystic lesions. Of these dentitions, 85.9% of teeth had normal pulp vitality and 14.1% were negative before marsupialization. Following marsupialization, preservation of pulp vitality was noted in 61.3% and 18.0% of teeth lost their vitality. Of those without normal dental pulp vitality, 70.9% of teeth recovered their vitality of which 46.5% had recovered their vitality 9 to 12 months following marsupialization.Marsupialization followed by second surgery maybe a treatment option for preserving and recovering the pulp vitality of teeth associated with large cystic jaw lesions.
