ABSTRACT
Abstract This systematic review aimed to answer the following question: What is the estimated prevalence of pulp canal obliteration in subtypes of traumatic dental injury (TDI) in deciduous and permanent teeth? The searches were conducted in PubMed, Embase, Scopus, Web of Science, LILACS, Grey Literature, and Google Scholar, and complemented by a manual search, until April 16th, 2023. Observational studies were selected based on population, exposure, and outcome (PEO) (P, deciduous or permanent teeth; E, TDI; O, pulp canal obliteration). Two reviewers (kappa 0.90) applied the eligibility criteria, extracted qualitative data, and assessed the methodological quality using the Newcastle-Ottawa tool. A meta-analysis was performed using MedCalc 17.2. Thirty-four articles were selected after screening. The methodological quality was moderate to high. The estimated prevalence of pulp canal obliteration was 27.6% (95%CI: 18.7-37.7) and 21.9% (95%CI:16.0-28.4), for permanent and deciduous teeth, respectively. Considering the TDI subtypes, the prevalence of pulp canal obliteration was higher in root fractures of the permanent teeth (78.6 %, 95%CI: 62.8-90.9) and lateral luxation injuries in deciduous teeth (29.4%, 95%CI:19.1-41.0). Our review of 34 articles of moderate and high methodological quality found that the prevalence of pulpal canal obliteration ranges from 21.9% to 27.6%. Pulp canal obliteration was most frequently detected following lateral luxation injuries of the deciduous teeth and root fractures of the permanent teeth (PROSPERO CRD42020179438).
ABSTRACT
RESUMEN: El objetivo: de este reporte es presentar el tratamiento endodóntico de un diente ante-rior con obliteración del canal radicular, con la ayuda de la endodoncia guiada. Paciente masculino sin antecedentes médicos relevante, y en tratamiento ortodóntico. Diente 2.1 con historia de traumatismo dento-alveaolar y presencia de dolor a la percusión. En la TCHC se observa obliteración total del canal radicular en el tercio cervical y medio y un área de radiolucidez apical. Diagnóstico: Periodontitis apical Sintomática. Tratamiento: Terapia de canal No vital, con planificación virtual y guía endodóntica. Se utilizó el programa de acceso gratuito, Bluesky Plan®, para la planifica-ción digital de la guía endodóntica. El tratamiento se realizó en dos citas. Conclusión: el uso de tecnología para la resolución de casos de alta complejidad en endodoncia, podría ayudar a mejorar el pronóstico de estos dientes y ser una alternativa más segura para reducir la posibilidad de perforación y preservar estructura dental.
ABSTRACT: The aim: of this case report is to present the endodontic treatment of an anterior tooth with an obliterated pulp canal, with the help of guided endodontics. Male patient with no relevant medical history, currently with orthodontic treatment. Tooth 2.1 had a history of dental trauma and presented tenderness to percussion. The CBCT exam showed a completely obliterated root canal in the cervical and middle third, and apical radiolucency. Diagnosis: Symptomatic Apical Periodontitis. Treatment: Root canal treatment with virtual planning and endodontic guide. Bluesky Plan® free access program was used for the digital planning of the endodontic guide. The treatment: was made in two sessions. Conclusion: the use of technology for the resolution of high complexity cases in endodontics could help improve the prognosis of these teeth and be a safer alternative to reduce the possibility of perforation and preserve more tooth structure.
