ABSTRACT
OBJECTIVES: Our aims were to evaluate the Vitapex pulpectomy (PE) success rate, Vitapex resorption rate, and their associated factors in primary teeth.
MATERIAL AND METHODS: This retrospective study evaluated the clinical records of Vitapex PE-treated patients at the Pediatric Dental Clinic, Mahidol University, from 2013 to 2019. The patient’s and pulpectomized tooth’s characteristics, procedure, materials used, and type of operator were recorded. A dentist evaluated and compared the periapical lesion, root status, obturation quality, and Vitapex resorption on preoperative, immediate, and follow-up digital radiographs. PE failure was defined as radiographic lesion progression.
STATISTICAL ANALYSIS: The Kaplan-Meier method was used to estimate the Vitapex PE success rate and Vitapex resorption rate. Multivariate Cox regression was used to determine the related factors.
RESULTS: In total, 647 Vitapex PE teeth from 448 patients (19-121-month-old) were analyzed. The follow-up periods ranged from 6 to 60 months. The success rate was 88.9 and 68.1% at the 12- and 24-month follow-up, respectively, and remained stable at 53.8% at the 36 to 60-month follow-ups. The factors related to Vitapex PE failure were age and a preoperative pathologic lesion. More than 50% of the pulpectomized teeth presented Vitapex resorption faster than physiologic root resorption at the 12-month follow-up. The patients’ age at treatment and the obturation quality were significantly related to the Vitapex resorption rate.
CONCLUSIONS: The success rate of Vitapex PE decreased time dependently and was related to the patient’s age at treatment and a preoperative lesion. The Vitapex resorption was faster than root resorption and was associated with the patient’s age at treatment and the root filling extravasation.
