Radix Entomolaris in mandibular molars: An Endodontic Challenge
Mandibular molars can have additional root located lingually) the radix entomolaris). If present, an awareness and understanding of this unusual root canal morphology can contribute to the successful outcome of root canal treatment. The root is typically smaller than the distal root and is usually curved, requiring special attention when root canal treatment is being considered for such a tooth. The aim of the paper is to present a case of permanent mandibular first molar with additional third root.
Radix Entomolaris in Mandibular First Molars: Report of 3 Cases
Research, Society and Development, 2021
The radix entomolaris is an anatomical variation characterized by the presence of an additional root located in the distal-lingual region of mandibular molars. An accurate diagnosis is necessary to plan and institute effective endodontic therapy for teeth with this condition. The aim of this report was to present three cases of endodontic management in permanent mandibular first molars with radix entomolaris using contemporary technical resources. For diagnosis, periapical radiographs indicated the possibility of morphological alterations, which were confirmed in two cases by cone beam computed tomography (CBCT). Ultrasonic tips and magnification with operative microscopy were the auxiliary resources used for locating the root canals, which were prepared with NiTi rotary instrument systems and filled with gutta-percha by using the lateral condensation technique and AH Plus sealer. Resources such as periapical radiography, CBCT, magnification with operative microscopy, ultrasonic dev...
Radix entomolaris in mandibular first molars in Indian population: a review and case reports
Case reports in dentistry, 2012
Purpose. The aim of this paper is to present cases of mandibular first molars with an additional distolingual root and their management using appropriate instruments and techniques. Basic Procedures and Main Findings. Mandibular molars can sometimes present a variation called radix entomolaris, wherein the tooth has an extra root attached to its lingual aspect. This additional root may complicate the endodontic management of the tooth if it is misdiagnosed or maltreated. This paper reviews the prevalence of such cases in Indian population and reports the management of 6 such teeth. Principal Conclusions. (1) It is crucial to be familiar with variations in tooth/canal anatomy and characteristic features since such knowledge can aid location and negotiation of canals, as well as their subsequent management. (2) Accurate diagnosis and careful application of clinical endodontic skill can favorably alter the prognosis of mandibular molars with this root morphology.
A novel clinical endodontic approach: Radix entomolaris
International journal of dental science and research, 2013
Aim: The present case report discusses the treatment of an endodontically treated mandibular molar tooth with three roots and four canals. Two canals were present in the mesial side and one each was present in the disto-buccal and disto-lingual side. Background: Mandibular molars may have an additional root which may be located buccally or lingually. When it is buccally located it is called as radix paramolaris and when lingually located it is termed as radix entomolaris (RE). Hence, the presence of such a pulpal system calls for challenges in providing endodontic treatment. Case description: A female child of 13 years age, reported to the Department of Pedodontics & Preventive Dentistry with a chief complaint of lancinating pain in the lower back region of the right side of the mandible. The pain was present for last two months. On clinical examination, the mandibular first molar of right side was deeply carious with tenderness on percussion. Intra oral periapical radiograph showed carious lesion involving enamel, dentin and pulp along with an extra root between the distal and mesial roots. To confirm that additional root is present, two intra oral periapical radiographs with different horizontal angulations were taken. After taking radiographs, an additional root was confirmed to be present on the disto-lingual side of the mesial root. Final diagnosis of irreversible pulpitis was made. The treatment modality planned was root canal treatment.
Radix entomolaris in mandibular first molars—an endodontic challenge
Indian Journal of Dentistry, 2011
Awareness of morphological variations of the tooth can contribute to the successful outcome of the endodontic treatment. The morphological variations of the mandibular fi rst molar radix entomolaris (RE) in terms of root inclination and root canal curvature demand careful clinical approach to avoid procedural errors during endodontic therapy. This paper describes 2 case reports of mandibular fi rst molar with RE.
Endodontic management of radix entomolaris : Case reports
JOURNAL OF MULTIDISCIPLINARY DENTAL RESEARCH, 2020
The clinician's knowledge and familiarity with the root canal anatomyplays a crucial role in the identification of variations in the anatomy like extra canals and roots. Inability to recognize and negotiate these variants lead to failures. The mandibular first molar is reported to be involved in root canal procedure more often, as it is one of the initial permanent posterior teeth to erupt. This tooth type exhibit reasonable variations in the number of canals and roots. One such variation is an extra root in the lingual termed the Radix Entomolaris. This article is a report of two cases describing the management of the first mandibular molars with Radix Entomolaris.
Introduction: For successful endodontic treatment a comprehensive knowledge of the root canal anatomy is a basic prerequisite. Usually the permanent mandibular first molar has 2 roots mesial and distal. But they can show considerable anatomic variations which can affect the crown, number of roots and number of canals. Radix entomolaris is a form of additional root present disto lingually. Case Report: We present a case of radix entomolaris in a 12 year old child patient which was successfully treated endodontically and emphasised its early diagnosis radiographically and knowledge about its prevalence, diagnosis, morphology, canal configuration , and clinical approach. Conclusion: RE is an uncommon anatomical variation and can be easily detected on oral radiograph (IOPA-Intraoral Periapical) if evaluated properly. Misdiagnosis of such a morphological variation can leads to incomplete biomechanical preparation of the tooth leading to endodontic failure. Also if such a tooth is indicated for extraction it can lead to procedural difficulties.
Radix entomolaris, an anatomical variation of mandibular molars: clinically relevant considerations
Brazilian Journal of Development
Knowledge about both the external and internal anatomy of teeth is essential for the success of endodontic treatment. The mandibular molars are prone to anatomical variations such as the presence of an additional root located lingual to the tooth which is named Radix Entomolaris (RE). The aim of the present study was to describe the internal and external morphology of RE, as well as evaluate the prevalence, etiology, and clinical protocol of this atypical anatomy by means of a literature review. The knowledge of these anatomical variations as well as clinical guidelines for the diagnosis and endodontic treatment of RE can minimize procedural errors during root canal preparation, and provide an adapted clinical approach for the dentists, thus culminating in the success of endodontic treatment.
Endodontic Management of Radix Entomolaris: Case Report
IOSR Journal of Dental and Medical Sciences, 2017
Mandibular molars exhibit varied root canal morphology which makes the endodontic treatment challenging. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. Success of endodontic treatment depends on proper identification and localization of all the canals, thorough chemo-mechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Hence, for a successful root canal therapy, clinician must be aware of the external and internal anatomic variations This report discusses endodontic treatment of mandibular molar with a radix entomolaris which is a rare macrostructure.
