“…In 2017, a study performed a descriptive analysis of potential predisposing factors based on 334 patients with ECR and conclude that sex did not seem to be a risk factor (Mavridou et al, 2017). A history of orthodontic therapy, trauma and poor oral health were the most associated factors (Chen et al, 2021b;Gijón et al, 2016) and others reported any that favour the activation of clastic cells, including biomechanical forces; mechanical, surgical and chemical trauma; endodontic microorganisms and their toxins; developmental defects; neoplasia; and hormonal disturbances (Chen et al, 2021a;Gijón et al, 2016;Patel et al, 2018a). The absence of all these factors and a radiographic examination contributed to the diagnosis of the present case as idiopathic etiology.…”

“…Dental resorption can be classified as internal or external and according to the Andreasen Classification, which is the most frequently cited in the literature for classifying resorption through its location, type and presence or absence of trauma, external cervical resorption (ECR) can be further categorized as inflammatory, replacement, and surface resorption (Aidos, Diogo & Santos, 2018;Patel, Lambrechts, Shemesh & Mavridou, 2018b;Mavridou, et al, 2016) and characterized by progressive loss of dentin through the continued action of osteoclast cells with the invasion of the cervical region by fibro vascular tissue (Chen, Huang & Deng, 2021a;Patel et al, 2018b;Patel, Mavridou, Lambrechts & Saberi, 2018c) The damage of cementum exposes the root surface to the osteoclasts, which then causes dentin resorption (Patel et al, 2018c). Clinically, usually presents asymptomatic because as ECR proceeds, resorptive tissues extend circumferentially or horizontally in the dentin while leaving the pulp intact.…”

“…ECR was used to be considered as a rare disease due to a lack of case reports and its prevalence rate varied from 0.02% to 0.08% (Chen et al,2021a;Howait, Shaker, Aljuhani & AlMohnna, 2021). However, in recent years it has received increasing attention due to the growing number of clinical cases, especially due to greater access by people to advanced means of diagnosis as digital radiography and the higher level of knowledge of this issue by the professionals, which leads to identifying more cases at their early stages (Consolaro, 2016…”

Introduction: External cervical resorption (ECR) is a physiological or pathological event usually detected on radiographic examination, since there are no symptoms in its initial and intermediate phases. Objectives: This case is an important finding because the early detection of this lesion allowed an effective multidisciplinary approach to be carried out. Case Report: Radiography was taken in a 55-year-old male and revealed a radiolucent area on the distal surface of the permanent mandibular left first molar, suggesting ECR with impaired pulpal vitality. Based on the clinical and radiographic examinations, a multidisciplinary approach was established involving endodontic treatment, periodontal surgery and indirect restoration that provided an option for preserve the affected tooth. The early diagnosis of ECR was essential for the successful treatment in order to maintain the satisfactory function for five-year follow-up. Conclusion: Despite the procedures performed, the idiopathic etiology of the lesion contributed to the appearance of recurrences; however, monitoring and maintenance of the affected tooth proved to be important for the longevity of the treatment.

“…According to the Glossary-Contemporary Terminology for Endodontics, resorption is defined as a condition associated with either a physiologic or a pathologic process resulting in a loss of dentine, cementum, and/ or bone 25 . There are different reasons for three different types of resorptions explained in literature; External root resorption, Internal root resorption and Replacement resorption [26][27][28] . Internal root resorption occurs because of ongoing pulpal pathologies whereas external root resorption are associated with trauma and orthodontic tooth movement.…”

Endodontic Considerations in Contemporary Orthodontic Practice- A Review

Introduction: With increase in number of adult orthodontic patients, the orthodontic- endodontic related patients are also expected to rise. There are number of clinical dilemma where both the specialties need robust guideline for clinical decision making. The effect of orthodontic force is expressed in different way in different patients and teeth which need to be understood by clinicians. On the contrary, the tooth movement of endodontically involved teeth demands careful evaluation of the tooth and its surrounding tissue, quality of root treatment, presence or absence of peri-apical pathologies, previous history of trauma etc. Management of external apical root resorption following orthodontic therapy might be challenging some time. Orthodontic extrusion of fractured teeth is one of the viable prosthetic rehabilitation options where orthodontic, endodontic and prosthodontics specialties are involved. So this review article will focus on reviewing current level of evidence on orthodontic- endodontic interface.

“…The loss of dental root tissue from teeth affected by ECR was found to reach 58% in the most advanced cases [ 6 ]. If the diagnosis is made in the early stages of resorption, the prognosis for the tooth is better, since the amount of remaining intact tooth structure has a significant influence on the prognosis [ 7 ].…”

The prevalence and characteristics of external cervical resorption based on cone-beam computed tomographic imaging: a cross-sectional study

Objectives This study investigated the prevalence and characteristics of external cervical resorption (ECR) regarding sex, age, tooth, stages of progression, and portal of entry, using cone-beam computed tomography (CBCT) scans. Materials and Methods CBCT scans of 1,313 patients from a Brazilian subpopulation comprising 883 female and 430 male patients (mean age, 55.2 years), acquired using a PreXion 3D CBCT unit, were evaluated. All permanent teeth included in the scans were evaluated for the presence of ECR according to the 3-dimensional classification and the portal of entry. The association between the presence of ECR and the factors studied was assessed using the χ 2 test. Intra-observer agreement was analyzed with the kappa test ( α = 0.05). Results In total, 6,240 teeth were analyzed, of which 84 (1.35%) were affected by ECR. A significant association was found between the presence of ECR and sex, with a higher prevalence in male patients ( p = 0.002). The most frequently affected teeth were the mandibular and maxillary central incisors. The most common height was the mid-third of the root. For the portal of entry, 44% of cases were on the proximal surfaces, 40.5% on the lingual/palatal surface and 15.5% on the buccal surface. Intra-observer agreement was excellent. Conclusions The prevalence of ECR was 1.35%, with a higher prevalence in male patients and a wide age distribution. The mandibular and maxillary central incisors were the most commonly affected teeth, and cases of ECR most frequently showed a height into the mid-third of the root and proximal entry.
