Teeth in mandibular fracture lines is common in maxillofacial trauma, but their retention or extraction is a matter of controversy. The aim of this study was to determine the factors related to retaining or extracting teeth situated in mandibular fracture lines and to decide the best treatment option.

Lectin (ScLL) has been recently evaluated in the oral cavity due to its anti-inflammatory activities. ScLL could be a promising agent for blocking osteoclast activity and preventing root resorption. The aim of this study was to evaluate the effect of ScLL on the viability of the RAW 264.7 macrophage lineage, osteoclast-like maturation and the release of TNF-α and nitric oxide (NO).

Propolis has been suggested as a storage medium for avulsed teeth. The aim of this study was to compare the effectiveness of Brazilian propolis with Hank’s balanced salt solution and milk in maintaining the viability of human periodontal ligament cells, their osteogenic differentiation potential, and pro-inflammatory cytokine expression.

Previous studies have compared the thickness of the device with and without grooves. The result was a difference in thickness of the device along the groove. The aim of this study, was to assess the differences in thickness of mouthguards that result from different groove shapes of ethylene vinyl acetate sheets used to make these appliances.

The type of storage media for short-term storage of an avulsed tooth is a critical determinant for the success of tooth replantation. If immediate replantation of an avulsed tooth is not possible, it is advised to store the tooth in a suitable storage medium. The viability and clonogenicity of periodontal ligament fibroblasts (PDLF) determines the success of replantation of an avulsed tooth. The aim of this study was to evaluate the effect on the clonogenic capacity of PDLF’s upon storage in Hank’s balanced salt solution (HBSS) and egg albumen.

Lateral luxation injuries are a type of traumatic dental injury in which the tooth becomes displaced in the palatal/lingual or labial direction. This injury is common amongst children and can result in pulp canal obliteration or pulp necrosis. The objective of this systematic review was to gather existing data on lateral luxation injuries to immature teeth to evaluate their overall prognosis.

Trauma is the leading cause of morbidity and mortality in the pediatric population worldwide, and Israel is no different in this aspect. Of these injuries, craniofacial trauma is a significant cause of morbidity in the pediatric population. The high occurrence of pediatric trauma is possibly related to a lower perception for the hazards that surround them, combined with the restless and adventurous nature that is typical of children. The aim was to perform a retrospective, epidemiological study on facial trauma in children examined in the emergency room in order to analyze the different patterns in pediatric maxillofacial trauma, to emphasize this data and educate those involved in preventing and treating children’s injuries.

Traumatic Dental Injuries (TDI) occur frequently at school environment. Many studies have shown that teachers' knowledge on emergency management of TDI is inadequate. The aim of this study was to evaluate the knowledge level among schoolteachers in Chennai, India, regarding TDI using a questionnaire and to evaluate the effectiveness of a newly developed audiovisual aid (AV) as an educational tool by reapplying the questionnaire.

Successful replantation of an avulsed tooth depends on the regeneration of periodontal ligament (PDL) attachment which is affected by the transport medium, dry time and storage time. Various storage media have been studied but the search for the optimum storage medium is still needed to determine the ideal material and storage time to maintain PDL cells. The aim of this study was to determine the ability of Custodiol® , coconut water from different stages of maturity and propolis as storage media for avulsed teeth by evaluating the viability of PDL cells for different time intervals.
