Taurodontism refers to change in tooth shape caused by the failure of Hertwig’s epithelial sheath diaphragm to invaginate at the proper horizontal level. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cemento-enamel junction are the characteristic features. Although permanent molar teeth are most commonly affected, this change can also be seen in both the permanent and deciduous dentition, unilaterally or bilaterally, and in any combination of teeth or quadrants. In performing root canal treatment on such teeth, one should appreciate the complexity of the root canal system, canal obliteration and configuration, and the potential for additional root canal systems. Introduction The term taurodontism comes from the Latin term tauros, which means ‘bull’ and the Greek term odus, which means ‘tooth’ or ‘bull tooth. Taurodontism can be def...

The management of this clinical condition requires a good understanding of the complexity of the problem as well as the variety of treatments available. The objective of this review article is to provide a brief overview of the diagnosis, etiology and clinical management of dentin hypersensitivity and to discuss technical approaches to relieve sensitivity.

A clinician must be aware of various paths that a root canal can take to the apex. Pulp canal system is complex and the canals may branch, divide and rejoin. External morphologic features that can be seen in teeth are crown size, root length, and division of roots. Internal anatomic variations occur in root canal configuration . Complex root canal system with atypical variations is a common finding among mandibular premolars. Endodontic treatment in these teeth may not be successful due to the failure to recognise and treat multiple canals Failure to recognize all these anatomical complexities often result in treatment failure.

An opening called the retromolar foramen (RMF) and a canal called retromolar canal (RMC) are known to be present in this area. The RMF is an anatomical structure on the alveolar surface of the retromolar triangle. The contents of the RMC have been reported to consist of branches of the inferior alveolar vessels and nerves. Retromolar area is related to surgical procedures that may lead to unexpected bleeding or paresthesia. Aims and Objectives: (1) To determine the prevalence of RMF and RMC in the mandible using cone-beam computed tomography (CBCT). (2) To observe variations, if any, in the appearance of the same. (3) To determine the length of the RMC, diameter of RMF, and proximity (distance) of the RMF from the cementoenamel junction (CEJ) of the mandibular molars. (4) To propose a classification for the presentation of the RMC. Materials and Methods: A retrospective analysis was carr...

Methodology: Agar plates were prepared using Mueller Hinton Agar and cultures were grown in BHI broth at 37 degrees centigrade. Lawn culture was carried out on Mueller Hinton Agar plates. Well diffusion method was used to derive the results. Wells were cut in agar plates which were 6 mm in diameter and 4 mm in depth. Then 50, 70, 90μl of fresh juice obtained from Allium cepa, P. emblica and Zingiber officinale was poured in the wells using a micropipette with sterile tips. Plates were incubated for 48 hrs at 37 degrees centigrade. Then agar plates without the culture but with wells containing 30μl fresh juices were also prepared as a negative control to confirm that the juices as well as the plates were free of contamination. Sodium hypochlorite was taken as a positive control. Result: results were calculated by measuring the zones of inhibition in mm. using a transparent ruler which were: 1. P. emblica: 29mm 2. Z. officinale:R 3. A. cepa: 23mm 4. Sodium hypochlorite:25mm Further study is being conducted to prove it statistically by altering the volume of the various juices used. This study can open up new pathways in search of herbal alternatives that can be used against E faecalis that is known to cause endodontic treatment failure.

Most commonly used posts are custom or prefabricated. the prefabricated posts include glass fiber, carbon fiber, metal or ceramics. However, till date none of the available posts meet all the biological requirements. this study is a biological approach for restoration of extensively damage teeth. case report: (clinical consideration): A "biological" restoration technique using dental fragments and adhesive materials is described. these fragments were obtained from extracted human teeth which had been previously sterilized and shaped to be used as intraradicular posts. conclusion: the use of dentin post is an alternative technique for reconstruction of extensively damaged teeth as it provided the excellent adhesion, strength to remaining tooth structure, and retention to the crown.

A recent increase in the treatment options of discoloured teeth has led to the development of various new techniques and materials. With recent development in bleaching techniques, many auxiliary apparatuses have been introduced for efficient bleaching. AIM: The purpose of the present study is to compare and evaluate the efficacy of In-office bleaching 37.5% hydrogen peroxide and At-home bleaching 15% Carbamide peroxide using different activation systems. MATERIALS & METHODS: Total of 80 freshly extracted human incisor teeth were selected, sectioned below CEJ and further stained using extra strong black tea and kept for 24 hours. The samples were thoroughly washed and cleaned of external stains and evaluated for pre-shade using spectrophotometer. Samples were divided into groups and bleached using different concentrations, methods and activation systems. Post shades were evaluated and the samples were subjected to statistical analysis. RESULT & CONCLUSION: Carbamide peroxide (15%) used in home bleaching is as effective as 37.5% hydrogen peroxide. On comparing in-office (37.5% hydrogen peroxide) with at-home (15% carbamide peroxide) it can be concluded that home bleaching with higher concentration of carbamide peroxide resulted in a better shade change. 37.5% hydrogen peroxide along with Laser activation resulted in superior immediate results but showed increased rebound of color after 1 week.

Apexification is induction of apical closure, the treatment of choice for necrotic teeth with immature root. Traditionally calcium hydroxide Ca(OH)2 has been the material of choice for apexification, recently Mineral Trioxide Aggregate (MTA) has been proposed as a potential material for formation of hard tissue apical barrier. Use of custom made posts or prefabricated posts may result in vertical root fracture during post space preparation. Use of an anatomical post results in better prognosis of the present case. This article highlights a case report of immature permanent tooth with Apexification using MTA followed by anatomic post and core. Case Description. A 16-year-old male patient complains of fractured and discolored teeth in upper front teeth region. Past dental history of discontinued endodontic treatment 8-years back. Treatment includes two phasesendodontic phase and re-construction phase followed by full crown porcelain fused metal prosthesis. Clinical Implications. Discussion focuses on reconstruction of endodontically treated tooth by selection of appropriate post and core from various materials available today. The present case report discusses about the custom made composite post and core in the management of endodontically treated tooth maxillary anterior tooth.

Nevertheless, proper diagnosis is critical to distinguish a fracture from clinical manifestations of periodontal and endodontic diseases. In as much as there are no specific symptoms, diagnosis can be as difficult. Clinical detection of this condition by endodontists is becoming more frequent, where as it is rather underestimated by the general practitioners. Early detection of a fractured root and extraction of the tooth maintain the integrity of alveolar bone for placement of a future implant with better prognosis. Since, vertical root fractures almost exclusively involve endodontically treated teeth; it often becomes difficult to differentiate a tooth with this condition from an endodontically failed one or one with simultaneous periodontal involvement. The diagnosis of vertical root fracture is difficult because of the delayed appearance of the signs and the appearance of pure endodontic or periodontal problems. Also, a tooth diagnosed for vertical root fracture is usually extracted, though attempts to reunite fractured root have been attempted in various studies with varying success rates.. Cone beam computed tomography has been shown to be very accurate in this regard. This article focuses on the diagnostic and treatment strategies, and discusses about predisposing factors which can be useful in the prevention of vertical root fractures.
