A wide variety of materials have been researched for their use as potential storage media for avulsed teeth, but it is essential to recognize the medium most recommended for improvement of the prognosis of avulsed teeth. The aim of this systematic review was to identify the most recommended medium to store and transport avulsed teeth based on the survival of periodontal ligament (PDL) cells as determined by in-vitro studies.

All Finnish males must attend compulsory military service that lasts from six months to one year. About 25 000 males (approximately 80% of each age cohort) and 400 volunteer females complete the service annually. The aim of the study was to investigate the types of dental trauma occurring among Finnish conscripts during their military service. The article also focused on how dental traumas is are treated in the Finnish Defence Forces MATERIAL AND METHODS: All dental records in the Defence Forces' patient register concerning dental trauma during the years 2011 and 2012 were analysed by tooth number, treatment procedures and number of visits RESULTS: According to the patient register, 361 conscripts suffered an oral trauma during their military service; thus, the average annual incidence was 7.2 trauma per 1 000 conscripts. A total of 483 teeth were traumatised in the two-year period. The most frequently traumatised teeth were the maxillary central incisors (61%), and the most common findings were enamel or enamel dentin fractures (63% of all findings). Severe trauma was ere not common, and the most severe ones occurred during off-duty hours. The most common treatment was direct filling (n=189 patients). Only 53 patients had soft tissue injuries (bruises, wounds). Among patients with dental trauma, the mean number of visits to the Defence Forces' dental clinic was 1.9. Great variation exists in recording findings concerning dental and oral trauma CONCLUSION: Minor trauma is common. In all cases recording trauma and treatments should be done carefully.

The prognosis of traumatized teeth can be optimized if appropriate procedures are following at the time of the accident. The aim of this study was to evaluate the level of knowledge of students' parents from a group of Brazilian schools regarding fracture and tooth avulsion in permanent teeth METHODS: Parents of 802 students were interviewed using a pre-tested questionnaire designed to explore how they would manage their child’s dental avulsion or fracture.

Tooth replacement in the anterior maxilla is most often indicated after traumatic dental injury or due to congenital missing teeth. Treatment alternatives include implant-supported restorations, conventional fixed bridges, acid-etched bridges, orthodontic space closure, or autotransplantation. Dental implants have gained increased popularity over the last 40 years. However, this treatment modality is contraindicated in patients with continuous growth of the alveolar process due to the risk of severe infrapostion of the dental implant. Likewise, conventional fixed bridges are often contraindicated in young individuals since large dental pulp chambers increase the risk of pulp necrosis, and acid-etched bridges are still considered temporary solutions due to questionable long-term retention. Orthodontic space closure may be indicated in young individuals. However, it is not always feasible for functional or aesthetic reasons. This article is protected by copyright. All rights reserved.

The impact of traumatic dental injuries (TDI) in the primary dentition on oral health-related quality of life indicates the need for the planning of prevention strategies. The aim of this study was to assess whether anthropometric characteristics in early life are associated with TDI by preschool age MATERIALS AND METHODS: A birth cohort was recruited from the public healthcare system in the city of Porto Alegre, Brazil. Socio-demographic variables, type of birth, head circumference, weight and length were collected at birth (WHO standards). Head circumference, body mass index for age and height for age were collected at 12 months. TDI (Andreasen criteria) at three years of age (n = 458) were recorded by two examiners who had undergone training and calibration exercises. Multivariable analysis was carried out with Poisson regression with robust variance RESULTS: A total of 31.0% of the children (142/458) exhibited TDI at three years of age. In the final model, the risk of TDI was 47% higher among children with a smaller head circumference upon birth and nearly 60% higher among those who were overweight/obese at 12 months of age (RR: 1.58; 95% CI: 1.15-2.17). The risk of TDI was also significantly higher among boys (RR 1.50; 95% CI: 1.13-2.00), but the outcome was not significantly associated with socioeconomic variables or other anthropometric variables CONCLUSION: Overweight/obesity in early life is a risk factor for TDI in preschool children.

There appears to be much confusion or misinformation worldwide regarding mouthguards and their use in sports. In an effort to clarify where the international dental community stands on mouthguards and mouthguard research, the workshop looked at some important questions. The goal is to one day formulate consensus statements related to these questions, which will be based on current scientific evidence-based research, to motivate the international community of the importance of dentally fitted laminated mouthguards and the wearing of them by athletes of all sports. There are only five sports in the USA that require the use of mouthguards. If through workshops such as this, the importance of wearing dentally fitted laminated mouthguards can be demonstrated, then more sports may require their athletes to wear them.

The prevalence of work-related oral trauma is underestimated because minor dental injuries are often not reported in patients with several injuries in different parts of the body. In addition, little data are available regarding their characteristics. The aim of this epidemiological study was to determine the prevalence, types and characteristics of occupational traumatic dental injuries (TDIs) in a large working community.

The surface roughness of dental materials can make cleaning difficult, thus facilitating retention of food debris and accumulation of microorganisms. The aim of this study was to assess whether thickness, color and the polishing process influence the surface roughness of ethylene-vinyl-acetate (EVA) sheets and the amount of microorganisms that adhere to them.

Fabrication of mouthguards should be performed properly. However, the appropriate heating temperature for fabricating a pressure-formed mouthguard has not been determined. The aim of this study was to examine the influence of the heating temperature on the fabrication of a pressure-formed mouthguard.

As reported in the literature by several authors, there is a great variation between countries in terms of etiology and patterns of mandibular fractures. The aim of this study was to determine the incidence of mandibular fractures at the Oral and Maxillofacial Surgery Unit, “Dr. Domingo Luciani” Hospital, Venezuela during the period January 2010 to March 2013.
