Intentional Replantation – The novel technique for the management of separated instrument in apical third of tooth: A case report

Intentional replantation is a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this article, intentional replantation is described and discussed as a treatment approach for failed root canal treatment with broken instrument periapically in mandibular second molar.

Prevalence of Distal Cervical Caries in Mandibular Second Molar caused by impacted third molar

Aim: To analyse early recognition of the distal cervical caries of mandibular second molar caused by impacted mandibular third molar, to correlate oral health and caries status and to find out the average age groups and gender affected by impacted third molar Methods: A cross-sectional survey of 300 participants was conducted over a 15-month period at Rehmat Memorial Hospital, Abbottabad. 300 participants having impacted third molar having distal cervical caries in mandibular second molar were analyzed clinically and radiographically. Data was analyzed using SPSS version 23.0 Results: the demographic data of 300 patients with impacted mandibular third molars were analyzed. 64% were male and 36% female that have extractions due to impaction. Caries caused in more than half of participants by mesioangular impaction, which was 52%, 3% due to distoangular, 26% due to distal, and 18% due to horizontal impaction. In 63.25% of cases, teeth were lost due to caries, periodontitis caused 20.25% of tooth loss, pericoronitis 7.75%, orthodontics 3.75%, prosthodontics 1.2%, trauma 1%, and other factors were 2.5%. study reveals that 30.5 % of the extractions were done from 21 and 30 years and 23 %of extractions were performed. 40% of those who took part in the study did not brush their teeth. Socioeconomic status also has a great impact on tooth extractions. Conclusion: After conducting this study, it was concluded that there was a relationship between the prevalence of distal cervical caries in mandibular second molars and the placement of neighbouring impacted mandibular third molars. As a result, the extraction of mandibular third molars should be done to avoid cavities and premature tooth loss in the neighboring molar. Key words: Third molar impaction, distoangular, distal cervical caries, extraction, 2nd molar caries

A Successful Individual Endodontic Treatment of Severely Curved Root Canals in Mandibular Second Molars: A Case Report

Background and Overview The incidence rate of severely curved root canals in mandibular molars is low, and the root canal treatment of mandibular molars with this aberrant canal anatomy may be visibly and technically challenging. Case Description A 26-year-old Chinese female patient presented with intermittent and occlusal pain in the left mandibular second molar. The patient had undergone caries for filling restoration before endodontic consultation. With the aid of cone beam computed tomography (CBCT), a large periapical radiolucency was observed, and curved root canals in a mandibular second molar were confirmed, depicting a severe and curved distolingual root. Nonsurgical treatments, including novel individual preparation skills and techniques and the use of bioceramic materials as an apical barrier, were performed, and complete healing of the periapical lesion and a satisfactory effect were achieved. Conclusions and Practical implications A case of a severely curved root canal in a mandibular second molar was successfully treated and reported herein. The complex anatomy of the tooth and the postoperative effect were also evaluated via the three-dimensional (3D) reconstruction of CBCT images, which accurately identified the aberrant canal morphology. Furthermore, new devices and biomaterial applications combined with novel synthesis techniques can increase the success rate of intractable endodontic treatment.

Tooth autotransplantation of the mandibular third molar: A case report

Autotransplantation is a viable option for treating teeth with severe decay when a donor tooth is available. Our case was a 29-year-old female that her mandibular second molar was non restorable due to extensive root caries. After extraction of mandibular second molar, the mandibular third molar was reimplanted into the recipient site. Root canal therapy was done for the third molar after two weeks.After15 months, clinical and radiographic examination revealed satisfactory outcome with no signs or symptoms suggestive of pathology.

A Geminated Mandibular Second Molar—A Case Report

Fusion and gemination are not entirely uncommon dental anomalies that may also be named ‘double teeth’. This is due to their unusual presentation in a twin-like fashion. Teeth with these irregularities may appear clinically similar, presenting as large and bulbous in shape with unusual anatomy and fissure patterns. The exact aetiology of these anomalies is uncertain, but many potential local or systemic disturbances during the morphodifferentiation stage of odontogenesis have been considered. Gemination occurs rarely in the permanent dentition and even less frequently in the posterior region of the oral cavity. This report presents a case of a geminated mandibular second molar and discusses the importance of early recognition and diagnosis of such teeth so that adequate preventative care and treatment can be provided.

Review in the Treatment Decision of Modalities for Impacted Second Molar

Impacted permanent tooth can occur on any tooth in the dental arch. The incidence of retention and impaction of the second molar lies between 0 and 2.3%. It is infrequently found in normal dental patients because most of the second molar impactions are asymptomatic. However, it is a common occurrence in orthodontic practice. The impacted second molar may provoke many pathologic disorders to the adjacent and opposite teeth, eventually malocclusions. There are many treatment modalities in facilitating the eruption of the second molar impaction. Early diagnosis and early treatment are crucial for the successful treatment of mandibular second molar impaction. This article presents an overview of various treatment modalities for an impacted second molar.

BILATERAL CONGENITALLY MISSING SECOND PREMOLARS IN A GROWING FEMALE PATIENT

Purpose- The aim of the current hypothesis is to contemporary a rare case report of congenitally missing bilateral mandibular second premolars in an adolescent patient and describe its management. The second premolars have the utmost incidence of congenital absence, after the third molars. The delinquent resides not in the prevalence of congenitally missing premolars but in the assortment of a management plan that will yield the best outcomes over the prolong period of time. The currenteducation reports a case of a 12-year-old female growing patient with bilaterally congenitally missing second permanent mandibular premolars with supplementary crowding of teeth. The case has been managed using a multi‑specialty methods, in which both deciduous mandibular second molars were sectioned and the distal half retained. The retained half was prepared to receive a full coverage restoration which was contoured as a premolar. The space created was then utilized to correct the crowding by fixed orthodontics. A two year follow up shows retained distal half of the deciduous mandibular second molar with correction of crowding and space closure.

Prevalence of Root Canal Configuration of Mandibular Second Molar Using Cone-Beam Computed Tomography in a Sample of Iraqi Patients

Introduction: The purpose of this study was to find out the prevalence of C-shaped canals configurations in mandibular 2nd molar and to investigate the gender prevalence. Materials and Methods: A sample of 1200 patients’ cone beam computed tomography (CBCT) scans were screened and evaluated by a maxillofacial radiologist assessed the axial, sagittal, and coronal sections. Inclusion criteria applied to 801 patients (452 females and 349 male) aged 14–75 years were included in this study with total of 1567 mandibular 2nd molar was evaluated. Inclusion criteria: Available CBCT images of mandibular posterior teeth with at least one mandibular 2nd molar in the scan, absence of root canal treatment, absence of coronal or post coronal restorations, absence of root resorption or periapical lesions, and high-quality images. Canal configuration was classified by criteria’s which described by Fan et al. (2004): (i) Fused roots, (ii) a longitudinal groove on the buccal or lingual surface of the root, and (iii) at least one cross-section of the canal belongs to the C1, C2, or C3 configuration. Results: Considering 801 patients, 97 (12.1%) patients females 57 (7.1%) and 40 (5%) males had a C-shaped canal with no statistical difference between females and males (P > 0.05). Conclusion: The occurrence of C- shaped canal mandibular 2nd molar is approximately 12.1% and no significant difference was found by gender.

Assessment of Electrosensitivity of the Pulp of the Mandibular Second Molar after Surgical Removal of an Impacted Mandibular Third Molar

Despite the frequent discussion of complications associated with surgical removal of wisdom teeth in the scientific literature, increased mobility of the second molar, which can affect the clinical status of the pulp, is often downplayed or overlooked. This study aimed to evaluate surgical removal of an impacted third molar on the change in the electrosensitivity of the pulp of the mandibular second molar. Sixty patients consecutively presenting to the Department of Oral Surgery to remove an impacted mandibular third molar were included in the study. Clinical examinations of pulp sensitivity of second molars in both the study and control groups were evaluated before the procedure, seven days after the procedure, and eight weeks after the procedure. The surgical removal of an impacted mandibular third molar significantly affected the pulp sensitivity of the second molar.
