BACKGROUND: Endodontic infections require the use of root canal dressings to reduce microorganisms, and studies of new intracanal medications are common. Two experimental intracanal medications that contain antibiotics and chlorhexidine have been proposed. However, given the composition of these medications, tooth discolouration with subsequent impacts on aesthetic parameters is a concern. The objective of this study is to evaluate tooth discolouration after the use of experimental intracanal medications for up to 180 days...

Tooth transposition is one of the most difficult dental anomalies to treat in the dental clinic. Several factors must be taken into account with a view of making the best decision. The aim of this study was to discuss treatment modalities for tooth transposition, their advantages and disadvantages. Additionally, it aims at presenting a clinical case of transposition between canine and lateral incisor in the upper quadrant on the right side. The treatment of choice was extraction of one transposed tooth. A multidisciplinary approach involving Orthodontics, Cosmetic Dentistry, and Periodontology was necessary to allow proper esthetic and functional outcomes to be achieved...

Actinomycosis is a rare, chronic, slowly progressive granulomatous disease caused by filamentous gram-positive anaerobic bacteria from the Actinomycetaceae family (genus Actinomyces). It has become a rare condition because of the widespread use of antibiotics. When clinical symptoms are not typical, diagnosis of this condition becomes difficult. This report describes a case involving an 82-year-old woman who was diagnosed with actinomycotic osteomyelitis of the mandible using matrix assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS)...

Background: Orthodontically induced external root resorption (OIRR) is a pathologic consequence of orthodontic tooth movement. However, the limitations of two-dimensional radiography suggest that cone beam computed tomography (CBCT) with its three-dimensional capabilities might be more suitable to assess OIRR. Objective: The aim of this study was to assess in an evidence-based manner data on linear or volumetric OIRR measurements of permanent teeth by means of CBCT, during and/or after the end of orthodontic treatment...

Stem cells constitute a non-specialised cell pool able for proliferation, self-renewal and differentiation into progeny constantly replacing used up tissue and/or organ fragments. They have been observed to be present in many tissue reservoirs, including stomatognathic system. Oral cavity seems to be a particularly attractive stem cells' source as these cells are richly present and easily accessible in dental and periodontal tissues and they can be used for therapeutic purposes. Their application is also morally and ethically non-controversial...

PURPOSE: Owing to volumetric changes after tooth extraction, lateral ridge augmentation has become a common procedure prior or simultaneous to implant placement. Nonetheless, little is known with regard to the dimensional remodeling after healing of these lateral ridge augmentation procedures. Hence, the purpose of this systematic review was to assess the stability of bone grafting material between augmentation procedures and final healing, in terms of resorption rate. MATERIALS AND METHODS: An electronic and hand literature search was conducted in several databases, such as the Cochrane Oral Health Group Trials Register, Embase, and Cochrane Central Register of Controlled Trials, up until February 2017...
