The dreaded fracture of a root canal instrument is in fact a rare adverse event. Most instrument fractures occur in molar teeth with the highest degree of root curvature. Various treatment options (leaving the fractured instrument with or without apicoectomy, bypassing or removing the fragment) and removing techniques (using ultrasonics, hollow tubes or bypassing and removing with debriders) are discussed. The clinical prognosis for teeth with fractured instruments is not necessarily compromised if appropriate further treatment is undertaken...

The aim of this study was to carry out a representative survey on the implementation of and experience with repairs of single-tooth restorations among dentists in the Canton of Zurich, Switzerland. An anonymous questionnaire was sent to all 1,411 dentists registered in the Canton of Zurich; 38.9% of the delivered questionnaires were returned and 35.3% could be evaluated. The statistical analysis comprised Kendall’s rank correlation coefficient (tau), Wilcoxon signed-rank tests, and Kruskal-Wallis tests. The level of significance was set at p≤0...

Anaphylaxis is defined as a serious allergic or hypersensitivity reaction in the most cases as a result of an IgE-mediated allergic reaction that is rapid in onset and may cause death. Common triggers are foods, insect stings, and medications. The medical treatment includes, epinephrine, glucocorticoids, antihistamines and inhaled bronchodilators, with the aim to prevent progression to life-threatening respiratory and/or cardiovascular symptoms.

Non-surgical periodontal therapy is often performed as a combinational approach using supplemental systemic amoxicillin and metronidazole. Better clinical outcomes, less need for periodontal surgery and limited systemic complications are arguments to justify such an approach. However, combination therapy with systemic antibiotic treatment is still a matter of debate due to emerging antibiotic resistance patterns. In this case report, a 61-year-old women suffering from an acute pancreatitis following systemic antibiotic combinational treatment as part of a non-surgical periodontal therapy is described...

An important part of endodontic diagnosis and treatment is the adequate visualization of root canal anatomy. The objective of the present study was to compare two different three-dimensional cone-beam computed tomography (CBCT) systems, Scanora 3D and 3D Accuitomo 170, with respect to their visualization of endodontic canal systems and potential pathological alterations. Seventy extracted human teeth were investigated with regard to the radiographic detection of number of root canals, lateral canals, root canal fillings and posts, vertical root fractures, and the occurrence of image artifacts...

Rupture of an atherosclerotic plaque is the usual initiating event in an acute coronary syndrome (ACS). Persistent thrombotic occlusion at the site of plaque rupture results in acute myocardial infarction. The early management of the patient is essential and crucially affects the prognosis of an ACS. Management includes the relief of ischemic pain and the initiation of an antithrombotic therapy, including an antiplatelet and anticoagulant therapy with aspirin and heparin to prevent further thrombosis of or embolism from an ulcerated plaque...

The restorative rehabilitation of the severe loss of dental hard tissue due to dental erosion or abrasion is a challenging situation for the dentist. The following article presents the case of applying direct adhesive composite restorations as one possible approach to reconstruct erosively-induced severe dental hard tissue loss.

Malocclusal traits can impair dental health and aesthetical appearance. The index of orthodontic treatment need (IOTN) identifies the patients who benefit the most from orthodontic treatment. The aim of this study was to assess the malocclusion frequencies and the orthodontic treatment need among Austrian children in the mixed dentition stage, since there is no pre-existing data from Austria. In the present study, 157 children aged between 8 and 10 years were examined. Following an anamnesis questionnaire, which included a question about the parents’ perceived treatment need, the children were examined clinically and dental impressions were taken...

Allergen-triggered lichenoid oral mucosa lesions may occur both in oral lichen planus (OLP) and oral lichenoid lesions (OLL). Clinically, OLP and OLL are difficult to distinguish from each other. An OLP should be checked by histological examination. Therefore all patients with OLP should be included into a close control interval due to the the potential malignant transformation, whereas in the literature a higher risk of malignancy is attributed to OLL in comparison with OLP. Based on a clinical case, it is demonstrated that an interdisciplinary approach in allergy and mucous diagnosis is necessary to verify the correaltion between a contact allergy to amalgam and the lichenoid mucosal lesions...

Vertical root fractures (VRFs) usually develop slowly, unnoticed by the patient until clinical signs and symptoms become apparent. In endodontically treated teeth, a VRF is a typical cause for extraction. The objective of the present study was the histologic analysis of VRFs in extracted, endodontically treated premolars and molars. In addition, clinical and radiographic findings of these VRF-affected teeth were retrospectively evaluated. Thirty extracted teeth with a clinically diagnosed VRF were embedded in methylmethacrylate...

Reliable analgesia can nowadays be achieved with several techniques and different anesthetic solutions, but side effects may be encountered. Severe and potentially fatal cardiovascular reactions can be the result of an intravascular injection. An easy to use, effective and safe alternative is the periodontal ligament injection. Nerve damage or cardiovascular side effects are not to be expected. This type of anesthesia can be of advantage for many dental procedures. With new devices like the computer-controlled local anesthetic delivery system, the periodontal ligament injection is a convenient way of local anesthesia for both patient and dentist...

The present study reports the results of a structured survey of graduates intending to evaluate the education at the Dental School of the University of Basel in the years from 2006 to 2014. In addition, dentists and practice owners supervising graduates from Basel in daily clinical routine or hiring them as assistant dentists were questioned. The aims of the current survey were (1) to analyze own subjective experiences, (2) to assess potential differences between the cohorts prior to and after the implementation of the Bologna reform, (3) to compare the rating regarding theoretical knowledge and practical skills, and (4) to disclose potential for improvement...

Extractions of mandibular third molars are a common procedure in dental practice. In cases where a close anatomical relationship of the root and the inferior alveolar nerve exists, the risk of transient or even permanent nerve injury increases. Nerve injury is difficult to manage and symptoms may cause severe patient discomfort, i.e. lifelong dysesthesia, i.e. painful sensation of the lower lip and chin area on the affected side. An alternative surgical procedure is coronectomy, which has first been described 25 year ago...
