RESUMEN
Mandibulo-acral dysplasia was first described by Young et al in 1971. It is a rare, autosomal genetic disorder describing characteristic general, craniofacial, and oral manifestations. However, the detailed characteristics of this multisystemic disease have not yet been clarified due to its rarity and the limited number of cases described. Through a clinical case, we have tried to expose some of the most common clinical and radiological signs especially in their bucco-facial location, some modalities of management and the importance of an early diagnosis which turns out to be a real challenge especially for dentists in their daily practice.
RESUMEN
Temporomandibular joint ankylosis is an important entity that dentists and maxillofacial surgeons should know about. It clinically manifests through a permanent limitation of mandibular movements coupled with mouth opening inferior to 3 cm. This serious pathology can have serious functional repercussions, such as mastication problems, speech troubles, eating disorders, and jaw growth hindrance, in addition to the psychological difficulties in coping with such a condition in daily life. Herein, we present a radiological and chronological illustration of the evolution of temporomandibular joint ankylosis following an overlooked traumatic fracture of the mandibular condyle. The present case report involves an 8-year-old patient referred for a gradually evolving mouth opening limitation following a car accident. Tomodensitometry was helpful as it revealed an osseous block between the left temporomandibular joint surfaces, showing an ankylosis. Posttraumatic cerebral computed tomography scan was performed. It revealed an undetected fracture of the left condyle. The aim of this paper was to show how a traumatic ankylosis could have been avoided if enough attention was paid to the interpretation of immediate posttraumatic computed tomography scans. A thorough dental examination must be carried out once vital emergency is over. Early diagnosis of temporomandibular joint trauma is a crucial factor in preventing complications, such as ankylosis and its consequent oral dysfunctions. The dentist must automatically suspect condylar fracture when a child presents a history of head trauma, especially a mandibular trauma. This case should be a reminder that although temporomandibular joints are very often left out in patients' vital emergency first examination, temporomandibular joints/they are still a highly important structure which omission, and thus, dysfunction, if lesions are present, can lead to nonnegligible medico-legal consequences/that temporomandibular joints should be taken into account during patients' vital emergency first examination because if they are neglected, in the presence of lesions, they cause dysfunction, thus leading to nonnegligible medico-legal consequences.
RESUMEN
BACKGROUND: Amelogenesis Imperfecta (AI) is a disorder of tooth development characterized by abnormal enamel formation. In order to detect other dental and jawbone abnormalities that could be associated with AI, a retrospective and analytic study was conducted comparing panoramic radiographs of AI and non-AI patients. MATERIAL AND METHODS: Digital panoramic radiographs of 60 AI and 60 non-AI patients were examined. Abnormalities in dental number, size, shape, eruption, and in the shape of the dental arches were checked and blindly recorded by two experimented observers. Descriptive statistics using percentages and chi-square test with .05 level of significance value was used. RESULTS: Prevalence of supernumerary teeth, dental agenesis, microdontia, taurodontism, radicular dilacerations, dental inclusions, temporary teeth persistence, and pulp calcifications was significantly higher in AI patients compared to control patients. Prevalence of periapical images, cysts, and hypercementosis was lower in AI patients compared to control patients, with no statistically significant difference. A significant prevalence of mandibular hypoplasia was also noted in AI patients. CONCLUSION: In addition to enamel defect, panoramic radiography was useful in detecting other dental abnormalities and mandibular hypoplasia associated with AI and should therefore be systematically indicated for AI patients' care.
RESUMEN
BACKGROUND: Enamel renal syndrome is a rare genetic disorder transmitted through an autosomal recessive mode. It is featured by a hypoplastic amelogenesis imperfecta, delayed tooth eruption, gingival fibromatosis, and nephrocalcinosis. The aim of this study was to describe clinically, radiologically, and histologically the main features of enamel renal syndrome and to point out the role of dentists in early diagnosing this genetic disease. MATERIALS AND METHODS: Our case of enamel renal syndrome was initially described by clinical, radiographic, and genealogic data, then complemented by ultrasound examination of the kidneys and microscopic observation of gingivae. RESULTS: The study showed the presence of amelogenesis imperfecta (AI), several teeth impaction, gingival hyperplasia, bilateral nephrocalcinosis, and multiple calcifications in pulp, gingiva, dental follicle, and kidneys. CONCLUSION: The patient was followed for a full mouth rehabilitation and also referred to a nephrology for global medical checkup. The dentist plays a key role in diagnosing genetic diseases and in referring patients for medical comprehensive care.
RESUMEN
Inflammatory granuloma caused by a vegetable foreign body is a lesion that can develop in the oral cavity. It results from the implantation of vegetable matter, leading to an inflammatory reaction and the development of bone resorption. This case highlights the importance of clinicians' awareness regarding this uncommon disorder.
RESUMEN
Introduction. Osteoid osteoma is a benign osseous tumor characterized by an excessive formation of unmineralized bone matrix. The aim of this study was to present, through a case report, the clinical and radiological manifestations of osteoid osteoma affecting the left basilar border of the mandible. Observation. A 30-year-old male patient presented with left mandibular pain of unknown etiology. The chief complaint was mandibular pain accentuating mainly at night, originating in the left basilar border, and radiating to the whole mandibular hemi-arch. Extraoral examination revealed a small, bone-consistent, and slightly painful swelling. Computed tomography scan revealed a well-limited, infracentimetric, and mixed osteolytic image with central nidus and peripheral osteocondensation. Histological examination revealed osteoid osteoma. Surgical excision of the lesion was performed, and the pain stopped immediately. Discussion. This benign tumor presents many clinical and radiological features similar to other lesions. To differentiate osteoid osteoma from these other bone pathoses, practitioners should have a clear concept and keen observation skills. Confrontation of the clinical, radiological, and anatomopathological data is therefore essential to establish the correct diagnosis and to determine the appropriate treatment plan.
RESUMEN
Stafne bone cavity belongs to the class of pseudocysts as a mandibular radiolucency image with well-defined borders. It is asymptomatic and incidentally discovered. CT scan is the best examination to identify characteristics and content of this image. This study aimed to highlight these radiological features to establish the correct diagnosis.
RESUMEN
We present two cases of AOT, the first case concerns a 23-year-old patient with an AOT located in the maxilla and the second case involves a 37-year-old patient presenting an AOT with mandibular localization.
