Prosthetic rehabilitation of atrophic maxilla and large maxillary defects can be done successfully by zygomatic implant-supported prosthesis. Zygomatic implants are an avant-garde to complex and invasive-free vascularised osteocutaneous flaps, distraction osteogenesis, and the solution to flap failures. A treated case of tuberculous osteomyelitis, with a class II (Aramany's classification) maxillary defect, reported to oral maxillofacial department, Government Dental College (RUHS-CODS). The defect in this group was unilateral, retaining the anterior teeth. The patient was previously rehabilitated with a removable maxillary obturator. Inadequate retention affected essential functions like speaking, mastication, swallowing, esthetics, and so on due to lack of sufficient supporting tissues. A fixed prosthetic rehabilitation of posterior maxillary defect was done with obturator supported with two single-piece zygomatic implants. At 1-year follow-up, the patient was comfortable with the prosthesis, and no further complaints were recorded.

Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disease. It is characterized by widespread soft tissue ossification and congenital stigmata of the extremities, affecting all ethnic backgrounds. The worldwide reported prevalence is approximately 1/2,000,000. Based on history and clinicoradiological findings, FOP should be diagnosed as early as possible and noninvasively. The hallmark of diagnosis of FOP is bilateral great toe anomaly present from birth. Misdiagnosis may lead to inadvertent managements, such as manipulations, biopsies, and surgery. Surgery, till now, does not seem to have any role in the management of this condition and may lead to further trauma and disease progression. FOP may be precipitated due to trauma to muscle. In masticatory muscle, it mainly affects masseter muscle and presents with symptom of trismus. Herein, we present a case of FOP which presented to us with trismus after wooden thorn injury and immobility of the left leg. This article also emphasize on diagnosis, precaution, and treatment of disease.

Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots and canals vary. The variation in the number of roots, if extra root located lingually called radix entomolaris (RE) or located bucally called radix paramolaris (RP). This article presents successful endo-dontic treatment of two mandibular frst molars with extra roots one is with radix entomolaris and other is with radix paramolaris, both of which are rare microstructures.
