“…It is also likely underdiagnosed in posterior teeth due to overlap of roots and greater difficulty in achieving ideal angulation to assess all the roots (especially for maxillary molars due to bucco‐lingual divergence of the roots). This may account for the higher prevalence of root resorption in posterior teeth reported as an incidental finding on CBCT compared with anterior teeth 92 . However, the findings of this study may be biased as the decision to take a CBCT scan was understandably not randomised for ethical reasons.…”

“…This may account for the higher prevalence of root resorption in posterior teeth reported as an incidental finding on CBCT compared with anterior teeth. 92 However, the findings of this study may be biased as the decision to take a CBCT scan was understandably not randomised for ethical reasons. CBCT scans may be a valuable adjunct when root resorption is suspected based on the history and clinical findings, or where it has been confirmed to be present on conventional radiographs but the extent is unclear.…”

Cone‐beam computed tomography (CBCT) is a three‐dimensional imaging modality which can aid endodontic diagnosis and treatment planning. While there are guidelines available describing the indications, there are divergent philosophies on when this technology should be applied in clinical practice. This paper reviews the applications of CBCT including the clinical relevance of parameters which can be assessed, highlights the limitations of this technology, and provides guidance on how to maximise its clinical utility.

“…IRR finding is very unusual in clinical practice since they are typically asymptomatic and their finding is ascribed to serendipity during standard radiographic examinations. According to Dao et al .,[ 12 ] the prevalence of internal resorption was the highest for anterior teeth (15.6%), almost four times greater prevalence for molars (4%) and almost two times greater prevalence than for premolars (8.3%). Furthermore, the most prevalent resorption types were external (29.3%), cervical (22.5%), infection-induced apical resorption (13.7%), internal (9.6%), and impacted tooth induced (8.8%).…”

The cases presented here aim to highlight the occurrence of a very rare internal root resorption (IRR) of inflammatory type among mandibular molars (prevalence 0.01%–1%). Patients reported in the outpatient department with a chief complaint of pain in the lower posterior region of the jaws, on thorough clinical and radiological examinations a diagnosis of irreversible pulpitis was made and nonsurgical root canal treatment was planned using thermoplastic obturation technique along with the use of magnification, cone-beam computed tomography, endosonics, and intracanal medicament to attain a successful outcome. Six-month follow-up showed arrest of IRR. This report of two cases with a literature review discusses the etiology, prevalence of IRR, the clinical decision, and the therapeutic management. Early detection of such resorption is the key to successful management and preserves the integrity of the tooth.

Este Estudio tuvo por objetivo determinar la incidencia de reabsorción radicular externa en premolares superiores e inferiores permanentes al finalizar el tratamiento de ortodoncia. Esta investigación fue realizada en pacientes entre 18 y 35 años que recibieron tratamiento de ortodoncia, sin extracciones, con técnica de autoligado en la ciudad de Guadalajara. Se consideraron 120 premolares, realizando mediciones longitudinales en las tomografías computarizadas de haz cónico al inicio y término del tratamiento. Utilizando el software Implant Viewer 3. Los valores registrados en el primer y segundo premolar superior tanto del lado derecho como izquierdo al inicio y término del tratamiento fluctuaron entre -4.946 y -7.801; p ≤ 0.0005 encontrándose diferencias estadísticas significativas. Mientras que en el primer y segundo premolar inferior tanto del lado derecho como izquierdo, fluctuaron entre -4.864 y -5.28; p ≤ 0.0005 encontrándose diferencias estadísticas significativas. Se concluye en este estudio que los dientes sometidos a movimientos durante el tratamiento de ortodoncia sufren modificaciones en el contorno de la raíz, cambios con consecuencias mínimas que no comprometen la funcionalidad del diente. Los premolares superiores presentaron mayores rangos de reabsorción radicular que los premolares inferiores.
