Hypophosphatemic rickets is a rare genetic disorder involving the regulation of fibroblast growth factor 23 (FGF23), a phosphaturic agent, clinically showing bowing of the legs, short stature and dentoalveolar abscesses. A 7-year-old boy, with previous hypochondroplasia diagnosis, was referred to our pediatric dentistry clinic presenting short stature, bone deformities and sinus tracts at deciduous teeth apex levels not related with trauma, restorations or dental caries. After deciduous teeth extraction, due to root resorption and mobility, light microscopy exhibited typical hypophosphatemic dentin, and micro-computed tomography revealed tubular clefts and porosities throughout the teeth...

Prior to the invention of cone beam CT, use of 2-D plain film imaging for trauma involving the mandible was common practice, with CT imaging opted for in cases of more complex situations, especially in the maxilla and related structures. Cone beam CT has emerged as a reasonable and reliable alternative considering radiation dosage, image quality, and comfort for the patient. This article presents an overview of the patterns of dental and maxillofacial fractures using conventional and advanced imaging techniques illustrated with multiple clinical examples selected from the author's oral and maxillofacial radiology practice database...

The aesthetics of the mouth are important in determining overall facial attractiveness. People with a relatively normal dental appearance are perceived as more attractive, more intelligent and more desirable as friends. Although the oral region comprises only 1% of the body area it accounts for 5% of all bodily injuries, and of facial injuries, dental injuries are the most common. A US survey among people aged 6-50 years showed that 1 in 4 had evidence of dental trauma.

INTRODUCTION: Dentoalveolar trauma is a very common and avulsion is the most frequent injury. Treatment of choice following avulsion is immediate reimplantation. However, in cases where this might not be possible the prognosis of reimplanted teeth can be improved by the selection of an appropriate storage media. Prevention of ankylosis and replacement resorption depends more on the potential of storage media to maintain cell viability rather than the extraalveolar time period. AIM: To compare and evaluate the efficacy of different storage media in maintaining the viability of Periodontal Ligament (PDL) cells in an avulsed tooth...

Craniofacial trauma is common in the pediatric population, with most cases limited to soft tissue and dentoalveolar injury. Although facial fractures are relatively rare in children compared with adults, they are often associated with severe injury and cause significant morbidity and disability. Initial evaluation of a child with facial trauma generally involves stabilizing the patient and identifying any severe concomitant injuries before diagnosing and managing facial injuries. The management of pediatric facial fractures is relatively more conservative than that of adults, and nonsurgical management is preferred when possible to prevent the disruption of future growth and development...

Adult dentoalveolar trauma most often occurs in the context of sports activities and traffic accidents. Coronal fractures are the most common type of lesion, followed by tooth luxation. We present the case of a 25-year-old woman who suffered alveolar bone damage and coronal fractures of the upper incisors, with extrusive luxation of the right central incisor, as the result of a fall. On the first visit, manual reduction of the buccal plate was carried out under local anesthesia, with repositioning of the right central incisor and splinting to the neighboring teeth...

Fracture of mandible can be classified according to its anatomical location, in which condylar fracture is the most common one overall and is missed on clinical examination. Due to the unique geometry of the mandible and temporomandibular joint, without treatment the fractures can result in marked pain, dysfunction, and deformity. The condylar fracture may be further classified depending on the sides involved: unilateral/bilateral, depending on the height of fracture: intracapsular (within the head of condyle), extracapsular - head and neck (high condyle fracture), and subcondylar (low condyle fracture), and depending on displacement: nondisplaced, displaced (anteromedially, medially, and lateral), and dislocated...

Trauma involving the dentoalveolar region is a frequent occurrence which can result in the fracturing and displacement of teeth, crushing and/or fracturing of bone and soft tissue injuries including contusions, abrasions and lacerations. This review describes the assessment of patients with these injuries, not in a didactic sense by repeating excellent already published classifications and treatment options, but by addressing questions that arise during assessment. It covers trauma first aid, examination of the patient, factors that affect treatment planning decisions, and the importance of communicating treatment options and prognosis to traumatized patients...

Dentoalveolar trauma, very frequent during childhood and adolescence, generally results in tooth fracture and/or partial or total luxation. Management of the pulpal and periodontal aspects of these traumatic cases is complex. The prognosis is improved if treatment is initiated promptly. Multidisciplinary management of these situations and regular patient follow-up make it possible to detect complications quickly and take the necessary action to maintain the teeth as long as possible in a healthy periodontal environment that allows harmonious development and the application of appropriate treatment in adulthood...
