The regeneration of damaged bone tissues to a pre-disease state has been a major goal for both clinicians and researchers worldwide. However, critical-sized bone defects which are unable to heal completely are a major clinical concern because effective, evidence-based regenerative therapy is still missing. Bone tissue engineering, aiming at providing novel and effective materials to promote bone regeneration, has been considered as a promising alternative to the traditional use of autografts, allografts and xenografts based on the fact that engineered bone tissue has limitless supply and has no disease transmission...

Reduction in postoperative edema and inflammatory reactions is the key to the posttraumatic regeneration process. Use of bromelain is well established in this indication, but there is some controversy with regard to the optimal dosing of this drug. The aim of our study was therefore to investigate the efficacy of dosage-dependent therapy with bromelain in patients after wisdom teeth extraction by comparing the registered dosage 1000 FIP (Fédération Internationale Pharmaceutique) against higher dosages of 3000 FIP and 4500 FIP...

BACKGROUND: Prophylactic removal of asymptomatic disease-free impacted wisdom teeth is surgical removal of wisdom teeth in the absence of symptoms and with no evidence of local disease. Impacted wisdom teeth may be associated with pathological changes, such as pericoronitis, root resorption, gum and alveolar bone disease (periodontitis), caries and the development of cysts and tumours. When surgical removal is carried out in older people, the risk of postoperative complications, pain and discomfort is increased...

INTRODUCTION: Adrenomedullin (ADM) is highly expressed in dental tissues at the critical developmental time points during tooth development. However, its role in pulp repair and pulp injury is still unknown. The study aimed to investigate the mechanisms by which ADM affects the proliferation and apoptosis of human dental pulp stem cells (DPSCs). METHODS: Fifty-four freshly extracted wisdom teeth were obtained from 27 patients with caries and 27 without. Enzyme-linked immunosorbent assay and immunohistochemistry were used to examine the expression levels of ADM in caries and normal pulp tissues...

Mandibular third molars are the most common impacted teeth. Mandibular first and second molars do not share the same frequency of occurrence. In rare cases the occlusal surfaces of impacted molars are united by the same follicular space and the roots pointing in opposite direction; these are called kissing molars. In some cases, a supernumerary fourth molar can be seen as unerupted and, in this case, such a supernumerary, deeply impacted fourth molar is seen neighboring kissing molars. The extraction of deeply impacted wisdom molars from the mandible may necessitate excessive bone removal and it causes complications such as damage to the inferior alveolar nerve and iatrogenic fractures of the mandible...

The debate regarding prophylactic extraction of mandibular third molar (Wisdom teeth) is not new. There is wide agreement among clinicians and researchers that an extraction in young age is easier and safer, but it may result in overtreatment, which means an unnecessary extraction of teeth that might have been functional and healthy. In order to avoid such overtreatment the clinician is obliged to be able to predict accurately the chances of third molar eruption, years before they are due to erupt. Additionally, the clinician has to estimate the chances for future pathology or infection that will force the patient to extract the tooth in years to come...

We report the successful management of general anesthesia for a patient with Pelizaeus-Merzbacher disease (PMD). PMD is one of a group of progressive, degenerative disorders of the cerebral white matter. The typical clinical manifestations of PMD include psychomotor retardation, nystagmus, abnormal muscle tone, seizures, and cognitive impairment. General anesthesia for a patient with PMD may be difficult mainly because of seizures and airway complications related to poor pharyngeal muscle control. In addition, the possibility of exacerbation of spasticity should be considered...

Periodontal disease is a chronic inflammation of the tooth supporting structures. It leads to bone and attachment loss which is irreversible. Extraction of horizontally impacted lower third molar (L3M) teeth may result in localized periodontal pockets at the distal aspect of the adjacent lower second molars (L2M). We present a case of a 21-year-old male who suffered from a swelling and pain around his lower right second molar following surgical removal of a mesioangular impacted lower right third molar. We showed that oral hygiene measures, surgical access, mixture of autogenous and synthetic bone graft, and guided tissue regeneration (GTR) were enough to control the problem...

Dental fear is the fourth most common fear among the population. Well-informed patients seemed to be less anxious, and have the least anxiety before a planned procedure. Our aim was to find out the ideal way of information required by the patient before extraction of an impacted wisdom tooth. A total of 129 patients listed for extraction of impacted teeth were randomly allocated into three groups: control group (n=42); video dubbed by the surgeon (n=43); and silent video (n=44). Their sociodemographic variables and baseline anxiety scores were comparable, and each group was assessed for anxiety: (1) three days preoperatively, (2) after they had watched a video, (3) immediately preoperatively and (4) postoperatively...
