BACKGROUND/AIM: Replantation of avulsed teeth may lead to root resorption. Bisphosphonates (BPs), a class of drugs of used to treat resorptive diseases of the bone such as osteoporosis and Paget's disease, have been observed to exert an anti-resorptive effect on periodontal bone as well. The anti-resorptive properties of BPs could prove them useful in preventing root resorption of replanted avulsed teeth. The aim of this systematic review was to analyze and summarise the currently available literature concerning the use of BPs in preventing root resorption of avulsed teeth...

BACKGROUND/AIMS: In epidemiological studies, traumatic dental injuries in children are usually determined from clinical signs or parents' reports. Radiographs are used in dental trauma centers but not in field surveys. The aim of this study was to evaluate the proportion of patients who present with radiographic evidence of trauma without any clinical signs of a history of TDI. METHODS: The prevalence of traumatic dental injuries was assessed from the records of 674 pre-school children at their first visit to a private dental practice...

BACKGROUND/AIM: The viability of periodontal ligament (PDL) cells is a significant determinant of the long-term prognosis of replanted avulsed teeth. A storage medium is often required to maintain the viability of these cells during the extra-alveolar period. Many studies have been carried out to search for the most suitable storage medium for avulsed teeth, but an ideal solution has not yet been found. The purpose of the study was to compare and analyze the ability of coconut milk and probiotic milk to maintain PDL cell viability...

The traditional dental curriculum presents limited opportunities for students to evaluate and treat patients with acute dental trauma. In an effort to increase student experiences, faculty at a dental school initiated and taught an interdisciplinary trauma course from 2014 to 2016. This course was elective, offered in the final year of dental school, and combined student-led and faculty-led case-based discussions of management of traumatic dental injuries with hospital trauma call shadowing. Modifications of the course were made based on student feedback...

A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man presented with a 5 × 1-cm laceration to the right cheek caused by a flying object propelled during the use of a lawn mower...

REVIEW
Enrique Bimstein, Ilan Rotstein
BACKGROUND/AIM: While some studies support the notion that the time elapsed from coronal fracture and treatment with Cvek pulpotomy in permanent teeth plays an important role in minimizing the possibility of pain and discomfort, microbial pulp invasion, and ensuring pulp and periodontal healing, others consider that neither time between the accident and treatment nor size of exposure is critical if the inflamed superficial pulp tissue is amputated to the level of a healthy pulp. This study compares published data in an attempt to assess whether the outcome of Cvek pulpotomies is affected by these factors...
