BACKGROUND/AIM: There is an increased risk of orofacial injuries in swimming pool facilities. Nevertheless, only a few studies have addressed this issue. The aim of this study was to identify the frequency of lip and tooth injuries at public swimming pools in Austria. A further aim was to examine which gender and age groups were affected, where and why these injuries occurred, and whether pool attendants had sufficient knowledge of dental first aid measures. MATERIAL AND METHODS: A total of 764 pool attendants in Austria were contacted by telephone and 689 participated in the study (90...

No well-established evidence supporting safe use of bisphosphonates (BPs) or other antiresorptive agents prior, during, or after dentoalveolar surgery, are currently available; moreover, the real risk of osteonecrosis of the jaw (ONJ) development is still unknown. The aim of the present systematic review was to assess the scientific literature concerning the implants placement in antiresorptive agent users and the related risk of implants failure and ONJ development. English papers published from January 2003 until December 2014 were identified on the MEDLINE database...

Seventy-two free-ranging American martens ( Martes americana ) in Michigan were immobilized using isoflurane from 2011 to 2015. In total, 129 anesthetic procedures were performed with no mortalities. Hypothermia and hyperthermia were the most common anesthetic complications, and the mean rectal temperatures were significantly higher during summer than in winter. Dental abnormalities were common; the majority of abnormal findings were broken or discolored teeth attributed to previous dental trauma and were not trap-induced...

BACKGROUND: Orthodontic treatment involves using fixed or removable appliances (dental braces) to correct the positions of teeth. The success of a fixed appliance depends partly on the metal attachments (brackets and bands) being glued to the teeth so that they do not become detached during treatment. Brackets (metal squares) are usually attached to teeth other than molars, where bands (metal rings that go round each tooth) are more commonly used. Orthodontic tubes (stainless steel tubes that allow wires to pass through them), are typically welded to bands but they may also be glued directly (bonded) to molars...

We report the case of postmortem animal depredation that produced initial confusion for investigators who responded to the scene. A decomposing elderly woman was found in her presumed home with bilateral upper extremity amputations and craniocerebral trauma. This raised suspicion of foul play. Subsequent investigations together with autopsy led the medical examiner to conclude that the cause of death was natural disease and that those injuries found on her body were produced by at least one of the dogs who shared the premises...

Among various biomaterials used as scaffolds in tissue engineering, silk fibroin is a highly attractive material. A scaffold should be biocompatible and nontoxic, with optimal physical features and mechanical properties. For this reason, tissue-engineering approaches in regenerative medicine have focused on investigating the biocompatibility of possible biomaterials by analyzing cell-scaffold interaction properties. The aim of the present study was to examine the biocompatibility of silk fibroin as a film (two-dimensional [2D]) and a scaffold (three-dimensional [3D]) after being cellularized with human dental pulp stem cells (hDPSCs)...

INTRODUCTION: The study examines how the shape of the teeth is taken into account in the context of facial hyperdivergency. One aim was to check out the widely-held belief that the hyperdivergent patient has long teeth. DISCUSSION: Our study found no link between the shape of the teeth and facial hyperdivergency, thus confirming the results in the literature. We examined the issue of how to characterize dental shapes. We found three diversely-appreciated types of shape: rectangular, triangular and ovoid...

INTRODUCTION: Tooth-arch discrepancy is a disproportion between dental volume and bone base. Extraction therapy can be a solution in case of excessive tooth volume and insufficient basal bone length. Techniques including bone distraction popularized by Ilizarov in the fifties allow the increase of the basal arch length in the maxilla as well as in the mandible. MATERIALS AND METHODS: We will describe the procedure of this dental arch length augmentation since the reflection about the therapeutic plan until the sufficient arch length is obtained and describe the indications of this orthodontic and surgical treatment in case of dental crowding, buccal and labial inclination and functional problems...

BACKGROUND: Paediatric specialist dental practitioners are often faced with the challenge of disruptive behaviour or refusal to comply with treatment. Behaviour management skills are an essential component of their role. However, little is known of the confidence or competence of practitioners in these approaches. AIM: To identify paediatric dentists' knowledge of behavioural management principles as applied to paediatric dentistry. METHOD: Postal questionnaire survey of all specialists in Paediatric Dentistry on the General Dental Council UK register (n = 234), using the Knowledge of Behavioural Principles as Applied to Children Questionnaire (KBPACQ; O'Dell, 1979) adapted for the dental setting...

This chapter describes a simplified method that allows the systematic isolation of multiple types of dental stem cells such as dental pulp stem cells (DPSC), periodontal ligament stem cells (PDLSC), and stem cells of the apical papilla (SCAP) from a single tooth. Of specific interest is the modified laboratory approach to harvest/retrieve the dental pulp tissue by minimizing trauma to DPSC by continuous irrigation, reduction of frictional heat from the bur rotation, and reduction of the bur contact time with the dentin...

Adult stem cells reside in body tissues to preserve organs and whole organism homeostasis. They are acquiring a prominent role in the contemporary medicine. Many protocols to isolate and cultivate adult stem cells have been so far described, though they are often lengthy, laborious, and require very expansive instruments, materials, and reagents. On this basis, we describe a simple, cheap but at the same time functional method to: (1) isolate dental pulp stem cells (DPSC), (2) expand and cultivate DPSC, (3) cryopreserve DPSC, (4) characterize DPSC, and (5) differentiate DPSC into both mesenchymal and non-mesenchymal lineages...

Background and Objective: Minor dental surgery is invasive and hemorrhagic. Thus, in patients treated with anticoagulants, the bleeding risk related to these invasive procedures is concerning. The aim of this meta-analysis is to evaluate this risk by comparing the post-operative bleeding rates of oral anticoagulation treatment (OAT) patients (without interrupted or altered anticoagulant intake) with non-OAT patients. Methods: PubMed, Embase and the Cochrane Library were searched for eligible studies that compared the post-operative (following minor dental surgery) bleeding rates of OAT patients without interrupted or altered therapy with those of non-OAT patients...
