A case is described where only topical anesthetic was used for suturing facial lacerations. The patient had sustained facial lacerations after a motor vehicle accident. After some initial treatment the patient refused injection anesthesia so only topical anesthetics lidocaine-prilocaine was used for one of the lacerations. Suturing was possible to perform with only topical anesthesia with good patient comfort.

A cross-sectional study was carried out in children and adolescents of both sexes, aged 1-15 years that sought dental emergency attention to the Regional Hospital between 2004 and 2007 in Temuco, Chile. The purpose of this study was to identify the aetiology, types of traumatic dental injuries in primary and permanent dentitions, sex and age distributions, accident location; and time elapsed before emergency treatment in children and adolescents. The sample consisted of 359 patients with 145 primary teeth and 525 permanent teeth affected by dental trauma. ⋯ A large proportion of children with dental trauma received delayed first emergency care, even 24 h after the accident. Considering the high frequency of traumatic dental injuries in 1-15 aged population and the high percentage of delayed emergency attention is necessary to develop effective educational campaigns in regard to causes, prevention and emergency management of traumatic dental injuries, especially in deprived areas. In conclusion, traumatic dental injury may be considered as a serious dental public health problem especially in children of deprived areas.

The purpose of this study was to review the etiology, incidence and treatment of selected oral and maxillofacial fractures in children in Belo Horizonte, Brazil, during a period of 3 years. ⋯ This study examined 566 facial fractures in 464 children of 18 years of age or less. The majority of fractures were observed in children within the age group of 13-18 years of age. Bicycle accidents were the major cause of trauma, followed by falls. The mandible was found to be the most common fractured bone in the facial skeleton, followed by the nose. A conservative approach was applied in most cases.

The aim of this cross-sectional epidemiological survey was to assess the prevalence of dental trauma in athletes representing 42 countries competing at the most recent Pan American Games (XV Pan Am) held in Rio de Janeiro, Brazil in July of 2007, and to determine prior use and type of mouthguard among this group of athletes. The examiners participated in standardization and calibration training sessions before the field phase began. Invitations were sent to >5500 participating athletes competing in 41 sports and to the Medical Committee of the Pan American Sports Organization before and during the XV PAN. ⋯ Based on the results of this study, nearly one-half of the subjects had experienced previous dental trauma; the majority related to sports activities. Furthermore, only 17% of the athletes reported prior mouthguard use; the most frequent mouthguards reported were boil-and-bite. These results suggest the importance of enhanced educational efforts and the use of properly fitted mouthguards to reduce dental trauma among athletes in international sports competition, especially in sports where mouthguards are not mandatory.

Comparative Study
Effect of temperature and storage media on human periodontal ligament fibroblast viability.
Many solutions have been examined as possible storage media for avulsed teeth. The purpose of this study was to compare the effectiveness of several storage media to preserve cultured periodontal ligament fibroblasts (PDLF) under different temperatures. The media tested were: sterile Hank's balanced salt solution (sHBSS), non-sterile HBSS (nHBSS), skimmed milk, Save-A-Tooth((R)), Minimum Essential Medium (MEM) and water (negative control). ⋯ The Save-A-Tooth((R)) had a detrimental effect on cells after 24 h. The influence of temperature on the effectiveness of the storage media tested showed at 20 degrees C a decreasing order of efficacy as follows: milk > sHBSS and nHBSS > MEM > Save-A-Tooth((R)) > water while at 37 degrees C it was: MEM > nHBSS > milk > sHBSS > Save-A-Tooth((R)) > water. In conclusion, incubation temperature altered the effectiveness of the storage media and skimmed milk at 20 degrees C was better than HBSS in maintaining PDLF viability.
