Frequency of concomitant injuries in maxillofacial trauma in a tertiary health care centre in India: A 5-year retrospective study.

PURPOSE: Road traffic accidents (RTA), assaults, falls, and sports-related injuries are the leading causes of maxillofacial trauma. Due to quite different geographical environment and fast urbanization, the use of various protective equipment is restricted in India. Thus, compared to other countries, there might be a significant difference in the pattern and frequency of associated injuries among subjects with maxillofacial trauma. The present study was conducted to identify the causes and pattern of various maxillofacial fractures and the frequency of other related injuries among subjects with maxillofacial trauma. METHODS: This is a cross-sectional retrospective study recording 2617 subjects with maxillofacial trauma. The patient demographics, causes of trauma, types of maxillofacial injury, and associated soft and hard tissue injuries were recorded. The types of maxillofacial and associated injuries were diagnosed from details of clinical examinations and the interpretation of various radiographs available in the file. The associated injuries were divided into head injury, other bony injuries, and soft tissue and vital structure injuries. Descriptive statistics and the test of proportion were used. A p value < 0.05 was considered as a level of significance. RESULTS: The maxillofacial injuries were significantly common in patients aged 16 - 45 years (66.7%) than in patients aged ≤ 15 and > 46 years (33.3%) (p < 0.001). The RTA was the most common cause of maxillofacial injury (n = 2139, 81.7%), followed by fall (n = 206, 7.9%), other causes of injury (n = 178, 6.8%), and assaults (n = 94, 3.6%). The maxillofacial injury by 2-wheel vehicle accidents was significantly higher than that by 4-wheel vehicle and other vehicle accidents (p < 0.001). There was a significant correlation between alcohol and RTA (p < 0.001). The head injury (n = 931, 61.1%) was the most common associated injury, followed by soft tissue and vital structures injuries (n = 328, 21.5%) and other bone injuries (n = 264, 17.3%). DISCUSSION: Head injury was the most common associated injury followed by soft tissue and vital structures and bone injuries among subjects with maxillofacial trauma. Clavicle fracture and injury to the lower extremities were the most common hard and soft tissue-associated injuries.

Decrypting the occurrence of mucormycosis following dental extractions: A systematic review.

BACKGROUND: Mucormycosis is a life-threatening opportunistic infection. The present systematic review was done to provide to date summary of the frequency of rhino-orbital-mucormycosis (ROM) cases following a tooth extraction, as there was no systematic review present till now to highlight it. METHOD: The PubMed, PMC, Google Scholar, and Ovid Embase databases were searched thoroughly with appropriate keywords till April 2022 including the human population with language restrictions including English literature to collate case reports and case series regarding post-extraction Mucormycosis. All the details of the patient's characteristics were extracted and presented as a table and evaluated on different endpoints. RESULTS: In total, we identified 31 case reports and 1 case series that results in 38 cases with Mucormycosis. The majority of patients belong to India (47. 4%). There was male predominance (68.4%) and involvement of maxilla was the most. Pre-existing diabetes mellitus (DM)(55.3%) was an independent risk factor for mucormycosis. The median period for the onset of symptoms was 30(14-75) days. 21.1% of cases presented signs and symptoms of cerebral involvement allied with DM. CONCLUSION: Dental extraction can trigger ROM by rupturing the oral mucous membrane. Clinicians should pay attention to the non-healing extraction socket which may be an early clinical manifestation of it, which is the key to tackling this deadlier infection.

Radicular variant of dens in dente (RDinD) in a patient undergoing radioisotope therapy.

Dense in dente is a developmental anomaly frequently encountered in permanent maxillary incisors, with a prevalence rate of 0.25-10%. Our review of the scientific literature on a radicular variant of dens in dente (RDinD) in permanent molar teeth identified only two reported cases with a confirmed diagnosis. Here, we report the third case of RDinD, in a 37-year-old woman presenting with nocturnal pain in the left maxillary second molar for 1 week. The patient had a medical history of surgery for papillary thyroid carcinoma followed by radioactive iodine therapy. We established a diagnosis of RDinD with an osteolytic lesion and transverse fracture line along the palatal root of the tooth by using cone beam computed tomography (CBCT). Extraction and periapical curettage of the lesion were performed, and the patient was followed up. In summary, we observed a rare clinical presentation of RDinD in the left maxillary second molar of a 37-year-old female patient.
