BACKGROUND/AIMS: In Lithuania, dental trauma cases are also treated by general dentists but it is unknown whether their age, self-evaluation of trauma knowledge and practice location can predict their actual knowledge and management of trauma cases. The aim of this study was to evaluate whether these factors can be used to predict the actual knowledge and management of trauma cases. METHODS: A two-part questionnaire included 17 multiple-choice questions about practitioners' demographics, their self-evaluated knowledge, and how frequently they treated traumatized permanent teeth as well as 13 clinical scenarios reflecting a variety of clinical trauma cases and their complications...

The Nestin gene encodes type VI intermediate filament and is known to be expressed in undifferentiated cells during neurogenesis and myogenesis. To regulate Nestin expression, the first or second intron enhancer is activated in a tissue-dependent manner, for example, the former in mesodermal cells and the latter in neural stem cells. Although Nestin has also been used as a differentiation marker for odontoblasts during tooth development, how Nestin expression is regulated in odontoblasts remains unclear. Therefore, this study aimed to compare the expression patterns of Nestin-GFP (green fluorescent protein) with that of endogenous Nestin in developing teeth of Nestin-EGFP (enhanced GFP) transgenic mice, in which the second intron enhancer is connected with the EGFP domain, at postnatal 7d, 3w, and 8w...

Traumatic dental injuries are reported to have a high prevalence regardless of the region or the age group. Concussion injuries are considered as moderate, but very frequent injuries. They are associated with a wide spectrum of pulpal reactions. Pulp canal obliteration in spite of negative sensitivity proves ongoing pulp vitality. This case report presents multiple traumatic dental injuries in both maxillary central incisors with two different pulpal reactions during a follow-up period of 4 years in a healthy 7-year-old girl...

BACKGROUND AND OVERVIEW: Unesthetic primary incisors can produce negative self-perceptions in preschool-aged children. In recent years, because of increased esthetic demands, prefabricated zirconia crowns have become increasingly popular. However, zirconia crowns cannot be crimped, and the clinician must prepare the teeth to fit the zirconia crowns. Therefore, extended preparation and fitting times are necessary, especially for inexperienced practitioners. A 1- to 2-millimeter subgingival feather margin also is required...

Dental injuries, especially of the incisors, caused by punches in violent criminal attacks could be seen in daily forensic casework involving the identification of injuries to a living body. Sometimes, when there is neither circumstantial evidence nor information about the surrounding circumstances, it is difficult to discern the cause of these injuries and the manner in which they were inflicted. As an example of clinical forensic medicine, we present the case of a 58-year-old woman whose teeth were injured when fighting with her son-in-law over household affairs with no witnesses present...

BACKGROUND: Traumatic tooth avulsion requires an urgent intervention to replant the tooth. Prolonged post-injury dry extra-oral conditions worsen the prognosis and increase the risk of root resorption. Fluoride has the potential to delay replacement resorption. Calcium silicate cements (CSC) are used to seal the root canal system and to stimulate periapical regeneration in immature open apex teeth (apexification). This report suggests the application of a novel fast-setting CSC with fluoride for apexification in an attempt to hinder root resorption...

Coronectomy is a widely-accepted technique available for the treatment of impacted wisdom teeth. The fundamental principle is to prevent trauma to the inferior dental nerve (IDN). Many publications have demonstrated its positive outcomes but there is no literature available regarding coronectomy of deciduous teeth. This case report highlights the complex approach to managing a severely infraoccluded 85 in the mixed dentition of a 10-year-old female. The report demonstrates and discusses the combined orthodontic and oral surgical approach to prevent damage to the IDN and to allow space for orthodontic movement...
