The prevalence of supernumerary teeth in non syndromic South Indian paediatric population is 1.24% with slight male predilection and conical mesiodens being the commonest.

Background and objectives Pain is the primary reason that dental patients seek endodontic therapy. The inferior alveolar nerve block (IANB) is the most frequently used mandibular injection technique for achieving local anesthesia for endodontic treatment. However, the IANB does not always result in successful pulpal anesthesia. Therefore, the purpose of this study was to determine the effects of preoperative administration of both ibuprofen and ketorolac on the efficacy of the IANB in patients with irreversible pulpitis. Methods A total of 60 patients diagnosed with irreversible pulpits of a mandibular posterior tooth randomly received identical capsules of either 400 mg ibuprofen or 20 mg ketorolac or a placebo 1 hour before the administration of a conventional IANB. Access was initiated after profound lip numbness was achieved. Success was defined as no, mild, moderate, or severe pain (verbal rating scale recordings) on accessing the dentin, pulp, and debridement. Results Ketorolac was associated with superior efficacy in pain reduction when compared with ibuprofen and placebo in all parameters, namely the dentin, pulp, and canal debridement. Interpretation and conclusion In conclusion, for mandibular posterior teeth, a preoperative dose of 400 mg of ibuprofen or 20 mg of ketorolac showed a statistically significant increase in the success of the IANB in patients with irreversible pulpitis.

Glass ionomer cement should be preferred over amalgam in conservatively prepared restorations as it reduces the microbial activities due to fluoride release.

<p><strong>Background:</strong> Electric pulp testers are widely used diagnostic tools in endodontics. Several factors can affect the result of electric pulp test like thickness of enamel and dentin, concentration of sensory fibres (A delta fibres), direction of dentinal tubules, pulp chamber size, neural elements etc. There are very few studies available in the literature which evaluated the variability of electric pulp response in molar teeth, which are more susceptible to caries. Hence aim of current study was proposed to evaluate response threshold in molars with respect to age and sex using electric pulp tester.</p><p><strong>Methods:</strong> Fifty volunteers aged between 20 to 69 years were recruited. The human subjects were divided into 5 groups of 10 each (5 males and 5 females) based on age. EPT was used with appropriate electrolyte as a conducting media. Seven sites on each molar crown were tested which includes mesiobuccal cusp tip, mesiobuccal cuspal surface, mesiobuccal gingival surface, centre of the supporting cusps (palatal of maxillary molar and buccal of mandibular molar), distobuccal cuspal surface, distobuccal gingival surface and centre of the guiding cusps (buccal of maxillary molar and lingual of mandibular molars). Statistical analysed using descriptive statistics and independent sample t test.</p><p><strong>Results:</strong> Mesiobuccal cusp tip showed lower response threshold values compared to other sites in all the groups. group 1 responded at lower threshold and group 5 at higher.</p><p><strong>Conclusions:</strong> The optimum electrode placement site for electric pulp test in molars is the mesiobuccal cusp tip irrespective of age and sex.</p>
