Traumatic gemination--triple tooth. Survey of the literature and report of a case.

Gemination and twinning are two rarely encountered developmental abnormalities. Although the precise etiology remains unknown, genetic predisposition is often suggested in the process. In the present study a maxillary incisor with three crowns of conical shape and three roots which were presumed to be the gemination of the tooth due to trauma, is reported.

[Mandibular distraction osteogenesis and dental rehabilitation by osseointegrated implants. A case report] ].

The authors report a case of mandibular reconstruction by distraction osteogenesis. The patient presented an interrupting mandibular defect secondary to a gunshot injury. The distraction osteogenesis permitted the reconstruction of the mandible without bone grafts or flaps. The attached gingiva on the alveolar ridge was also recreated by the distraction and allowed a dental rehabilitation by osseointegrated implants.

Incidence of injury in Texas girls' high school basketball.

We studied the incidence of injury in girl's varsity basketball to characterize injury demographics in high school athletics. We defined a reportable injury as one that occurred during organized practice or competition, resulted in either missed practice or game time, required physician consultation, or involved the head or face. We prospectively evaluated the athletes on team rosters during the 1993 to 1994 season from 100 randomly selected Class 4A and 5A Texas public high schools that employed full-time certified athletic trainers. The 890 student athletes from 80 schools ranged in age from 14 to 18 years. Four hundred thirty-six injuries were reported for a rate of 0.49 per athlete per season. Injury risk, calculated on the basis of exposure time, was 0.4% per hour per athlete. Although game time accounted for only 12.5% of exposure time, it represented one half of the total injuries. Sprains and strains (56%) were the most common injuries, followed by contusions (15%) and dental injuries (14%). Injuries to the ankle (31%) and knee (19%) were by far the most common. There were 34 severe injuries defined as requiring surgery or hospitalization, for a rate of 0.038 per athlete per season. Knee injuries were by far the most likely to require surgeries, and ACL injuries accounted for 69% of the severe knee injuries.

Rapid neurologic assessment and initial management for the patient with traumatic dental injuries.

The authors believe that a dental practitioner can be adept at observing insidious signs of neurologic impairment secondary to trauma of the head and neck. If approached logically in a systematic order, the course of neurologic assessment of a patient with traumatic dental injuries can be achieved in a short time. If neurologic damage is suspected, immediate medical referral is indicated, as impending neuropathologic crises of secondary injury may be prevented with definitive early care. Medical personnel will benefit in their diagnostic course from information gathered by the initial provider of health care. The dentist also provides a service to the patient by ruling out definite signs of neurologic deficit before directing complete attention to emergency dental procedures.

[Tetanus prophylaxis in injuries. Guidelines for the dental practice].

The severe and often fatal infection of tetanus is very rare in the Netherlands because of the mild Dutch climate and adequate vaccination programme. Nevertheless, in case of wounds, either extra- or intra-orally, tetanus prophylaxis should be considered. The immunity of the individual patient can be estimated by his vaccination record. Dentists see a large number of patients with dental trauma and/or facial wounds. Depending on the immune status of the individual patient, tetanus prophylaxis might be necessary. Especially at risk are patients with inadequate or deficient vaccination, e.g. those who spent their childhood abroad and patients who had their last immunisation over ten years ago. Vaccination in case of wounds should follow a strict protocol to prevent an inadequate tetanus prophylaxis.

Custom sports mouthguard modified for orthodontic patients and children in the transitional dentition.

Young athletes with ever-changing transitional dentitions and those wearing fixed orthodontic appliances can benefit from custom-formed protective mouthguards. Modifications of the traditional vacuum-forming method are useful to fabricate mouthguards for such patients and extend the useful life of these devices. The purpose of this case report is to document fabrication of custom-formed protective mouthguards for a 10-year-old boy wearing fixed orthodontic appliances and a 9-year-old girl with a fixed palatal expander in place.

Bicycle accident injuries.

Bicycle accidents in 210 patients are analysed. Ages ranged from 1 to 59 years (mean 14.5 years) with a male predominance. In 52% of patients there was a head or facial injury, 6% being moderate to severe. Of the fractures 64% involved the upper limb, 32% being of the radius and ulna and 22% of the clavicle. The majority of abrasions and soft-tissue injuries involved the limbs.

Traumatic injuries of the teeth: current treatment modalities.

Teeth that have been traumatized and exhibit craze lines, fracture into enamel, fracture into dentin, root fracture, concussion, or subluxation should be pulp tested 3 months after the accident. If the tooth has a vital pulp, root canal treatment likely will not be required. Teeth that have a crown-root fracture should receive immediate endodontic therapy, and--if needed--can be extruded orthodontically. An intruded tooth should have endodontic therapy the same day, with calcium hydroxide placed into the canal. Teeth that have been extruded, displaced in any direction, or totally avulsed must have the canal completely cleaned, shaped, and filled with calcium hydroxide within 1 or 2 weeks post trauma. Clinical research concerning traumatized teeth is ongoing, and it is incumbent upon each practitioner to keep abreast of the current literature. This review has discussed treatment modalities that are recommended at this time.

Traumatic dental injuries in children presenting for treatment at the Department of Pediatric Dentistry, Faculty of Dentistry, University of Jordan, 1997-2000.

Data pertaining to traumatic dental injuries of children seeking care at the teaching clinics of the Department of Pediatric Dentistry, Faculty of Dentistry, University of Jordan over a period of 4 years were analyzed. The prevalence of traumatic dental injuries was 14.2% from 2751 subjects. The peak incidence of injury was 10-12-year age group. Boys were more affected (18.3%) than girls (10.1%). Most injuries occurred at home (63.2%), and falls were the leading cause of injuries (49.9%). Most injuries involved one tooth (69.3%) and maxillary central incisors were the most affected teeth (90.4%). The commonest injury was uncomplicated crown fracture (62.5%), then complicated crown fracture (28.7%). Only 17.1% of children sought treatment the same day or the day after the injury. At the initial examination, cases seen after a long post-traumatic period required more complicated treatment than those presented within a short time period. Preventive educational program should be instituted in Jordan, directed at parents and school teachers to inform them about the importance of traumatic dental injuries and the benefit of immediate attendance for dental treatment. Furthermore, improving the knowledge of dental practitioners through continuing education would also help in minimizing sequelae of traumatic dental injuries.

Traumatic anterior dental injuries related to incisor overjet and lip competence in 12-year-old Nigerian children.

A study of 1016 12-year-old Nigerian children was carried out to assess the relationship between traumatic injuries of anterior teeth, incisor overjet and lip competence. The prevalence of dental injuries was 10.9% which confirmed the results of previous studies. More boys than girls sustained injuries to their teeth. There were, however, no significant sex differences in increased overjet or lip competence. Of the 111 children with traumatic dental injuries, 71 (64.0%) had increased incisor overjet (> 3 mm) compared to 257 of the 905 children (28.4%) in the non-trauma group. Similarly, 72 (64.9%) of the trauma group had inadequate lip coverage compared to 224 (24.8%) in the non-trauma group. These differences were statistically significant (P < 0.001). It is concluded that incisor overjet of more than 3 mm and incompetent lips are significant predisposing factors to anterior dental injury in Nigerian children.

Effect of treatment delay upon pulp and periodontal healing of traumatic dental injuries -- a review article.

Based on an analysis of the literature concerning parameters influencing the prognosis of traumatic dental injuries, few studies were found to have examined possible relationships between treatment delay and pulpal and periodontal ligament healing complications. It has been commonly accepted that all injuries should be treated on an emergency basis, for the comfort of the patient and also to reduce wound healing complications. For practical and especially economic reasons, various approaches can be selected to fulfill such a demand, such as acute treatment (i.e. within a few hours), subacute (i.e. within the first 24 h), and delayed (i.e. after the first 24 h). In this survey the consequences of treatment delay on pulpal and periodontal healing have been analyzed for the various dental trauma groups. Applying such a treatment approach to the various types of injuries, the following treatment guidelines can be recommended, based on our present rather limited knowledge of the effect of treatment delay upon wound healing. Crown and crown/root fractures: Subacute or delayed approach. Root fractures: Acute or subacute approach. Alveolar fractures: Acute approach (evidence however questionable). Concussion and subluxation: Subacute approach. Extrusion and lateral luxation: Acute or subacute approach (evidence however questionable). Intrusion: Subacute approach (evidence however questionable). Avulsion: If the tooth is not replanted at the time of injury, acute approach; otherwise subacute. Primary tooth injury: Subacute approach, unless the primary tooth is displaced into the follicle of the permanent tooth or occlusal problems are present; in the latter instances, an acute approach should be chosen. These treatment guidelines are based on very limited evidence from the literature and should be revised as soon as more evidence about the effect of treatment delay becomes available.

The incidence of hospital-treated facial injuries from vehicles.

The annual incidence rate of facial injuries from vehicle crashes, 278 per 100,000 residents, was determined from a population-based study involving all Dane County, Wisconsin, hospitals with emergency departments. Applying this figure to the U.S. population yields an estimated 625,000 hospital-treated facial injuries from vehicles occurring in the United States each year. Vehicle crashes were the source of a substantial proportion of facial injuries from all causes, and were found to be the single leading cause of the most severe facial lacerations and facial fractures. The majority of injuries were sustained by drivers and other vehicle occupants, and others by bicyclists, motorcyclists, and pedestrians struck by vehicle. Vehicle occupants' faces were most commonly injured by steering wheels and windshields. Technologies which are thought to protect occupants include airbags and nonlacerating windshields, but neither is available in vehicles currently manufactured for sale in the United States.
