Fibrodysplasia ossificans progressiva is a rare genetic disease of connective tissue in which muscles, ligaments, and tendons ossify either spontaneously or after trauma. Patients can develop physical disabilities and restriction of respiratory function. A patient attended a maxillofacial surgery outpatient clinic with severe trismus and mouth opening limited to 2mm. The risks of intervention were many from both anaesthetic and surgical perspectives, which prevented the extraction of carious teeth. The patient was referred to a special care dentistry team who provided endodontic stabilisation without local anaesthesia...

Treatment success of periodontal-endodontic lesions is dependent on the elimination of both disease causative factors, whether they exist separately or concurrently. This report presents successful endodontic management of a misdiagnosed large periradicular pathology, which had not resolved after a previous periodontal regenerative surgery. A patient complaining of discomfort in the left maxillary region was referred. He had undergone regenerative surgery for treatment of a large periradicular defect; however, there was no further amelioration of the clinical signs/symptoms...

Odontogenic maxillary sinusitis has now increasing incidence in dental and otorhynolaryngological practice. Its incidence varies from 10-12 % to 50-75 %, according to different authors. Literature study showed that odontogenic maxillary sinusites are mostly unilateral, and significantly differ in complaints, clinical signs, and diagnostic and treatment measures from other types of sinusitis. This should be taken into account, because often odontogenic maxillary sinusitis is misdiagnosed with common sinusitis, and only in 77 % such patients are examined by both dental specialist and otorhynolaryngologist...

Introduction: Cervicofacial subcutaneous emphysema is defined as the abnormal introduction of air in the subcutaneous tissues of the head and neck. It is mainly caused by trauma, head and neck surgery, general anesthesia, and coughing or habitual performance of Valsalva manoeuvre. The occurrence of subcutaneous emphysema after dental treatment is rare, and diffusion of gas into the mediastinum is much rarer, especially when the procedure is a nonsurgical treatment. Presented here is a case of subcutaneous emphysema that occurred after sodium hypochlorite irrigation during endodontic treatment, and the description of its etiologies and prevention during nonsurgical endodontic treatment...

Patients with periodontitis may have one or few teeth with hopeless prognosis, which would have to be extracted before initiation of orthodontic therapy. Periodontal therapy aims to prolong the lifespan of dentition, as preserving natural dentition is always the best treatment option. The decision to retain a tooth is always based on the probability of long-term success of one or more treatment modality. A 17-year-old female patient seeking fixed orthodontic treatment presented with the left mandibular first molar tooth (36) having hopeless periodontal prognosis with advanced primary periodontal and secondary endodontic lesion, grade III mobility, and grade II furcation involvement...

In the full-mouth rehabilitation of a patient with severely collapsed occlusion, a multidisciplinary approach including prosthodontics, orthodontics, endodontics, and surgery could provide better esthetic and functional results. Orthodontic treatment aiming for stable occlusion that meets the standard requirement of functional occlusion, enables the maintenance of occlusal function, and guarantees long-term stability on the basis of periodontal health was attempted. The essential element of this protocol is careful treatment planning based on the optimal sequence pursuing functional occlusion...

The analysis of dental students' clinical production/participation has been used to assess whether a prospective graduate is capable of unsupervised and independent practice (that is, competent to perform that practice). This method and others have inherent biases that may not accurately reflect whether the student has mastered the associated concepts and techniques required for dentistry. The aim of this study was to assess an informatics system that assigned curriculum meta-tags with time-based relative educational value units (ReVUs) to each clinical procedure performed by Medical University of South Carolina (MUSC) students...
