József Szalma, Edina Lempel
Coronectomy of lower impacted wisdom teeth is the partial removal of third molars, aiming to avoid inferior alveolar nerve injuries. The coronectomy procedure has several crucial points, such as the pulpal, periapical preoperative conditions of the tooth, the way of crown sectioning and decoronation, the wound closure and the length of patients' follow up. In addition it is important to identify and manage possible intraoperative or postoperative complications correctly. According to the literature, the complication rate of coronectomy is usually lower, than that of total teeth removal, furthermore considering inferior alveolar nerve injuries, coronectomy is significantly the safer procedure...

Human dental stem cells can be obtained from postnatal teeth, extracted wisdom teeth or exfoliated deciduous teeth. Due to their differentiation potential, these mesenchymal stem cells are promising for tooth repair. Therefore, the development of dental tissue regeneration represents a suitable but challenging, target for dental stem cell therapies. Areas covered: In this review, the authors provide an overview of human dental stem cells and their properties for regeneration medicine. Numerous preclinical studies have shown that dental stem cells improve bone augmentation and healing of periodontal diseases...

Odontoblasts have been suggested to contribute to nociceptive sensation in the tooth via expression of the transient receptor potential (TRP) channels. The TRP channels as a family of nonselective cation permeable channels play an important role in sensory transduction of human. In this study, we examined the expression of transient receptor potential vanilloid-1 (TRPV1), transient receptor potential vanilloid-2 (TRPV2) and transient receptor potential vanilloid-3 (TRPV3) channels in native human odontoblasts (HODs) and long-term cultured human dental pulp cells with odontoblast phenotyoe (LHOPs) obtained from healthy wisdom teeth with the use of immunohistochemistry (IHC), immunofluorescence (IF), quantitative real-time polymerase chain reaction (qRT-PCR),western blotting (WB) and immunoelectron microscopy (IEM) assay...

This study elucidates the question of whether chronic inflammation in the jawbone contributes to the development of Chronic Fatigue Syndrome (CFS). Fatty degenerative osteonecrosis in jawbone (FDOJ) may contribute to CFS by induction of inflammatory mediators. We examined seven cytokines by multiplex analysis in jawbone samples from two groups of patients. In order to clarify neurological interrelations, specimens from 21 CFS patients were analyzed from areas of previous surgery in the retromolar wisdom tooth area...

Osteomyelitis is an infection and inflammation associated with the bone structures: bone marrow, cortical bone, periosteum, blood vessels and nerves. Although it does not have a frequent presentation, it can sometimes lead to complications such as pathological fractures or even septicemia. We present a clinical case study, to assess the relationship between osteomyelitis of the jaw and pathological fractures, after the extraction of an impacted wisdom tooth. This case highlights a rare complication following the surgical removal of mandibular third molar; a slow evolution of the pathology following an extraction should lead to close monitoring of the patient both clinically and radiographically, albeit osteomyelitis is a rare complication, it should be included as one of the differential diagnosis of persistent post-extraction pain...

A middle-aged poorly controlled diabetic man developed left-sided orbital and facial swelling several days after extraction of a left upper wisdom tooth. The clinical impression was that of acute dacryocystitis. Opening the skin above the lacrimal sac failed to reveal an inflamed sac establishing the diagnosis of deep facial cellulitis. Complete resolution occurred few weeks after systemic antibiotics and repeated dental drainage of the tooth abscess.

OBJECTIVES: Regenerating critical-size bone injury is a major problem that continues to inspire the design of new graft materials. Therefore, tissue engineering has become a novel approach for targeting bone regeneration applications. Human teeth are a rich source of stem cells, matrix, trace metal ions, and growth factors. A vital tooth-derived demineralized dentin matrix is acid-insoluble and composed of cross-linked collagen with growth factors. In this study, we recycled human non-functional tooth into a unique geometric dentin scaffold, entitled perforated root-demineralized dentin matrix (PR-DDM)...

Introduction: Surgical procedures require informed patient consent, which is mandatory prior to any procedure. These requirements apply in particular to elective surgical procedures. The communication with the patient about the procedure has to be comprehensive and based on mutual understanding. Furthermore, the informed consent has to take into account whether a patient is of legal age. As a result of large-scale migration, there are eventually patients planned for medical procedures, whose chronological age can't be assessed reliably by physical inspection alone...
