BACKGROUND/AIMS: Dental root cell proliferation following tooth avulsion has not been well researched. Understanding the effects of dry time and dentin treatment influences on cell proliferation is essential to provide evidence-based guidelines for tooth replantation. The study evaluated the viability of periodontal ligament fibroblasts (PLF) in contact with roots, submitted to surface treatments with EDTA and hyaluronic acid (HA) at different times, including to quantify inflammatory cytokines IL-6, IL-8, IL-1β and TNF-α expressed by PLF...

BACKGROUND/AIMS: 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...

BACKGROUND/AIM: Avulsed teeth should be immediately replanted into the socket or otherwise kept in a physiologic storage medium to maintain periodontal ligament cell viability. A previous study has demonstrated that Thai propolis extract can maintain viability of human periodontal ligament cells. However, root resorption by osteoclasts often occurs when the avulsed teeth are replanted. The aim of this study was to determine the inhibitory effect of Thai propolis extract on human osteoclastogenesis in vitro...

An avulsed tooth should ideally be replanted as soon as possible. Periodontal ligament (PDL) cells may survive for a short time in dry storage or storage in some physiologic media, enabling healing with normal PDL.1,2 However, after delayed replantation, when the extra oral drying time is longer than 60 min, the cells of the PDL will not survive.2-8 Despite this, even after long periods of dry extra oral time, delayed replantation is recommended although these PDL cells are necrotic.9,10 In such teeth ankylosis and osseous replacement are unavoidable, and the tooth will be eventually lost...

Traumatic dental injuries (TDIs) account for a considerable proportion of bodily injuries. Nevertheless, global TDI frequency is unknown, probably because TDI diagnosis is not standardized. This study estimated world TDI frequency. A literature search (publication years 1996-2016) was aimed at covering as many countries, communities, ethnic groups as possible, thus achieving high generalizability. In particular, nonspecific keywords, no language restrictions and large databanks were used. Observational studies reporting proportions of individuals with at least one TDI (prevalence) and who developed TDI (incidence rate) were considered...
