The Uk

The number of dental radiographs taken in the UK has steadily increased over the past 20 years—recently estimating around 18 million taken in the general dental services alone, and dental radiographs now account for nearly 25% of all medical radiographic exposures.1 Radiographs remain our most useful diagnostic aid. Their strength is in demonstrating hard tissue pathology, which makes radiographs particularly effective in the maxillofacial region. Although well accepted in this capacity, there remain a number of limitations and drawbacks to conventional radiographs which recent developments have begun to overcome. There have been improvements in the scope and capabilities of dental imaging equipment. There has also been a continuing effort to reduce radiation-induced harm by limiting our exposure to it. This has been possible both through the introduction of new methods and protocols for reducing individual radiation exposures and by the creation of guidelines for selecting radiographs more effectively and thereby reducing the total number of radiographs taken.

Type Of Injury

AbstractTraumatic dental injuries affect 1 to 3% of the population, and disproportionately affect children and adolescents. The management of these injuries incorporates the age of patients, as children between 6 and 13 years of age have a mixed dentition. This helps to preserve the vitality of teeth that may be salvaged after a traumatic event. The clinical examination of these cases involves a thorough examination of the maxilla and mandible for associated fractures and any lodged debris and dislodged teeth or tooth fragments. The objective is to rule out any accidental aspiration or displacement into the nose, sinuses, or soft tissue. After ruling out any complications, the focus is on determining the type of injury to the tooth or teeth involved. These include clinical examination for any color change in the teeth, mobility testing, and testing for pulp vitality. Radiographic evaluation using periapical, occlusal, panoramic radiographs, and cone beam computed tomography is performed to view the effect of trauma on the tooth, root, periodontal ligament, and adjoining bone. The most commonly used classification system for dental trauma is Andreasen's classification and is applied to both deciduous and permanent teeth. Managing dental trauma is based on the type of injury, such as hard tissue and pulp injuries, injuries to periodontal tissue, injuries of the supporting bone, and injuries of the gingiva and oral mucosa. Hard-tissue injuries without the involvement of the pulp typically require restoration only. Any pulp involvement may require endodontic treatment. Fractures involving the alveolar bone or luxation of the tooth require stabilization which is typically achieved with flexible splints. The most common procedures employed in managing dental injuries include root canal/endodontics, surgical tooth repositioning, and flexible splinting. Recognition and treatment of these injuries are necessary to facilitate proper healing and salvage of a patient's natural dentition, reducing future complications to patients.

Introduction: Birth injuries although inevitable should be avoided to prevent unnecessary neonatal morbidities and mortalities as well as hospital litigations. Aim: To determine the incidence rate, pattern and outcome of birth injuries occurring in the Rivers State University Teaching Hospital. Materials and Methods: An observational prospective study was carried out in the Special Care baby Unit of the hospital. A pre tested proforma was used to collect demographic and pregnancy information from mothers and demographic data, delivery history, type of birth injury and clinical outcome from babies whose parents consented to the study. Results: Thirty-nine of the 5,692 babies delivered during the study period had birth injuries, giving an incidence rate of 6.9 per 1000 live births. The common birth injuries were neurological (26.2%), extracranial (23.8%) and soft tissue injuries (21.4%). Cephalopelvic disproportion (36%), diabetes mellitus in pregnancy (32%) and prolonged labour (20%) were commonly found complications of pregnancy among mothers whose babies had birth injuries. Birth injuries were commoner among males, babies born by normal vaginal delivery and those with birth weights between 2.5-3.9Kg. Neurological injuries were significantly associated with normal vaginal delivery and birth weights of ≥ 4kg while soft tissue injuries were significantly associated with Caesarean section, P value < 0.05. Although majority of them were discharged, mortality rate was 7.7%. Conclusion: Although the incidence of birth injury in this study was low, the morbidity and mortality associated with it are avoidable. Improved antenatal and delivery services are therefore necessary to reduce the incidence of birth injuries. Keywords: Birth injury; Incidence; Pattern; Outcome; Tertiary hospital; Nigeria.

Cellular Secretion

In the cellular secretion theory of mineral deposition, extracellular matrix vesicles are believed to play an integral role in hard tissue mineralization (1). Membrane limited matrix vesicles arise from the plasma membrane of epiphyseal chondrocytes and tooth odontoblasts by a budding process (2, 3). Nutritional and hormonal factors have been postulated to play essential roles in mineral deposition and apparently have a direct effect on matrix vesicles of calcifying cartilage as concluded by Anderson and Sajdera (4). Immature (75-85 gm) Long-Evans hooded rats were hypophysectomized by the parapharyngeal approach and maintained fourteen (14) days post-surgery. At this time, the animals were anesthetized and perfusion fixed in cacodylate buffered 2.5% glutaraldehyde. The proximal tibias were quickly dissected out and split sagittally. One half was used for light microscopy (LM) and the other for electron microscopy (EM). The halves used for EM were cut into blocks approximately 1×3 mm. The tissue blocks were prepared for ultra-thin sectioning and transmission EM. The tissue was oriented so as to section through the epiphyseal growth plate from the zone of proliferating cartilage on down through the hypertrophic zone and into the initial trabecular bone. Sections were studied stained (double heavy metal) and unstained.
