Septic arthritis of the temporomandibular joint as a complication of acute otitis media is rare in the Western world. This report describes the case of a 7-year-old boy who had pain in his right ear and limited mouth opening, following the onset of acute otitis media. A contrast-enhanced computed tomography scan revealed right-sided mastoiditis and hydrops of the right temporomandibular joint, suggesting septic arthritis. Real-time PCR and microbiologic analysis identified Streptococcus pyogenes and Staphylococcus epidermidis in the joint aspirate...

The prosthodontic management of complex rehabilitations requires several stages of treatment including one or more provisional restorations. The design and adjustments of the provisional are made to achieve an optimal functional and esthetic outcome for the patient. However, the adjustments needed are both time and cost consuming. Therefore, once a satisfactory provisional is made, the information should not be lost during the following stages of treatment. The purpose of this clinical case is to illustrate "digital cross-mounting," a procedure used to precisely transfer information from the provisional to the final fixed rehabilitation in a digital workflow...

In contemporary reconstructive periodontal and implant surgery, attaining uncomplicated wound healing in the early postoperative healing phase is the key to achieving a successful treatment outcome and is of central interest, from the clinical as well as the scientific perspective. The realization of primary wound healing is the central challenge in most cases. Two of the evidence-based factors that affect postoperative wound healing can be influenced by the surgeon: the blood supply to the surgical site and postoperative wound stability...

Andreja Kuliš, Igor Kopač
Patients with an Angle Class III malocclusion are generally treated by orthodontics with or without orthognathic surgery. A literature search revealed very few articles describing solely the prosthodontic treatment of a Class III malocclusion, as it is rarely used as a treatment modality in these cases. The purpose of this article is to show the effects and benefits of an increase in the vertical dimension of the occlusion (VDO) in patients with a Class III malocclusion. An increase in the VDO causes a clockwise rotation of the mandible, thereby increasing the reverse overjet...

#9
Tina Olsson, Daniel Chan, James D Johnson, Avina Paranjpe
OBJECTIVE: Spacers are commonly placed between the canal orifice and the temporary material between endodontic treatment appointments. This prevents the temporary restoration material from obstructing the canal orifices and allows for easy removal. Various endodontic spacers are currently used, including polytetrafluoroethylene (PTFE) tape. Previous in-vitro studies have demonstrated the advantages of using PTFE over using cotton; however, no in-vivo studies have demonstrated this. Hence, the purpose of this study was to evaluate which spacer showed less bacterial leakage between endodontic treatments...

For the past several thousand years, until development of the titanium dental implant, only a few missing teeth were replaced successfully in a very small number of individuals. Nowadays, placement of dental implants has become sufficiently commonplace that there is a need to interchange information between what we know about periodontal health and disease and what we know about health and disease involving dental implants. This review discusses the similarities and differences between teeth and dental implants with regards to anatomy, biology, physiology, and pathologic processes...
