Medication related osteonecrosis of jaw (MRONJ) is a rare iatrogenic disease. Cancer therapeutics is advancing exponentially and apart from a major emphasis on quality of life (QoL) in metastatic patients, now we are foreseeing increased longevity. This necessitates the rising need of betterment of supportive care modalities and looking into the rare complications of therapy. Bisphosphonates (BPs) and Denosumab, the anti-resorptive agents (ARAs) used commonly by medical oncologists in cancers with bone metastases and less commonly in prevention or treatment of osteoporosis, are implicated in the etiology of MRONJ. Many a times, it goes undetected, underdiagnosed and untreated due to lack of awareness, low index of suspicion and paucity of understanding of this disorder amongst medical oncology fraternity. A high index of suspicion is a cornerstone of timely diagnosis and therapeutic action. A regular collaboration between treating oncologist and dentist is of utmost importance.

Purpose: To evaluate the correlation between the palatal rugae pattern, face form and arch form among Indian population at Moradabad, India. Materials and Methods: Alginate impressions of maxillary arch was made and cast was poured immediately with type III dental stone. A sharp graphite pencil was used for marking outline of the rugae on the cast. A digital caliper was employed for measurement of length of palatal rugae. Palatal rugae were analysed in accordance with Thomas and Kotze classification. Arch form of these models was determined with using 3M Unite template. For assessment of the face form, the subjects were seated in an upright position on the operator chair and the camera was stabilized on a tripod. Then photographs of the frontal profile were taken. These photographs were used for the analysis of the face form. The data was subjected to one way analysis of variance test and Post Hoc test. Results: The average number of primary rugae (10.76%) were found to be more predominant than secondary (2.12%) and fragmentary rugae (1.54%). The most predominant shape of palatal rugae were curved (42.19%) followed by wavy (32.71%), straight (17.37%) and circular (0.92%). Based on the direction of the rugae, forward rugae (54.27%) were found more common followed by backward rugae (37.26%) and perpendicular rugae (0.55%). Base on the unification of rugae pattern, diverging rugae (4.55%) were found to be more common than the converging rugae (1.57%). The most common face form was ovoid (72.4) % followed by tapered (24.4%) and square (3.2%). The most prevalent arch form was ovoid (62.2%) seen followed by the tapered (26.0%) and square (4.8%) arch form. It was found that there was significant correlation between the face form and arch form among the study subjects (p<0.001). However, no correlation was found between the rugae pattern, face form and arch form (p>0.05). In term of arch form and face form, ovoid was the most common followed by tapered and square. Conclusion: Within the limitations of this study, it was concluded that there was significant correlation between the face form and arch form among the study subjects. However, no correlation was found between the rugae pattern with face form and arch form.

The knowledge of variations in root canal morphology significantly affects the success of endodontic treatment. This article presents the endodontic management of a unique case of mandibular molar with an additional distolingual root with two canals and radix endomolaris which is quite uncommon. Mandibular molars can sometimes present a variation called radix endomolaris, wherein the tooth has an extra root attached to its lingual aspect. Accurate diagnosis and careful application of clinical endodontic skill can favorably alter the prognosis of treatment.
