BACKGROUND: Bulimia nervosa is an eating disorder resulting in an intended weight loss due to decreased food intake, induced vomiting, or hyperactivity, and is observed frequently between 12 and 25 years of age. One of the complications is early tooth loss. Moreover, since bulimia nervosa patients suffer from increased atrophy of the alveolar processes, oral rehabilitation even with short dental implants may be impossible. In these cases, lateralization or transposition of the inferior alveolar nerve (IAN) followed by implant placement can be useful...

Successful intraoral rehabilitation for patients with head and neck cancer can be extremely challenging to both the patient and the physician due to anatomical, functional, and esthetic changes from the cancer and its treatment. The measures with optimal oral hygiene to prevent or minimize the sequelae of cancer treatments are fundamental to preservation of function and avoidance of complications of therapy. In patients with loss of teeth, endosseous (dental) implants offer an option to improve intraoral rehabilitation...

OBJECTIVE: Root canal obturation still is a relevant research topic and patients spend substantial amounts of financial resources for this step of endodontic treatment. Three experiments were conducted challenging the necessity of root canal obturation. METHOD AND MATERIALS: Applying micro computed tomography, the volume of dentin tubules that cannot be instrumented during root canal therapy was determined. Using a simple biofilm model of human tooth segments, the effect of root canal obturation on the persistency of bacteria was evaluated and freshly extracted root canal treated teeth were examined for bacteria remaining in dentin...

Squamous cell carcinoma (SCC) is an aggressive tumor and represents the most common oral malignancy found by dental health care providers. Timely detection is paramount to reduce patient comorbidities of regional and distant metastases and improve survival rates. To augment recognition of early stage of gingival SCC (GSCC), this article features the somewhat innocuous clinical findings in a 60-year-old female.

OBJECTIVE: The mere osseointegration of an implant should no longer be considered a satisfactory criterion for success. Tooth extraction itself and, more importantly, possible local comorbidities such as periodontal or endodontic diseases, cause a reduction in the gingival volume of the edentulous site due to bone atrophy. This reduced volume must be treated and resolved to obtain a satisfactory esthetic result, which is an essential factor for successful implant rehabilitation. The classic approach to this problem relies on bone augmentation procedures...

Chronic non-suppurative osteomyelitis (CNSO) is a chronic bone disease and may be associated with a reparative periosteum entity called proliferative periostitis (PP). This condition rarely affects the maxillofacial region. Mandibular cases were already described for an infectious dental cause, often with an "onion skin" radiographic aspect, but some rare reported cases showed no obvious etiology. They represent a challenge for diagnosis because of possible misdiagnosis leading to unsuccessful or inappropriate treatment attempts...

OBJECTIVE: Bone and soft tissue calcifications can often be visualized on panoramic radiographs, thus leading to presumptive diagnoses requiring further examinations. This cross-sectional study determined the prevalence of suspected carotid artery calcifications, tonsilloliths, calcified submandibular lymph nodes, sialoliths of the submandibular glands, and idiopathic osteosclerosis in a Lower Austrian subpopulation. METHOD AND MATERIALS: Digital panoramic radiographs (DPR) taken from 1,042 subjects for other clinical purposes between the years 2013 and 2015 were evaluated, using a standardized template...

OBJECTIVE: Adaptation of the surgical protocol and implant selection depending on bone quality has been advocated. It was the goal of this in-vitro study to quantify the effect of implant geometry and implant site preparation on micromotion at the implant-bone interface. METHOD AND MATERIALS: A parametric study was conducted with implants differing in shape, length, and diameter placed in polyurethane foam material differing in density and structure following various methods of implant site preparation...

A growing patient population is adolescents and young adults who have had one or more serious medical problems and are aging into adulthood. This group of patients has unique medical needs, which has resulted in the development of a specialized area of medicine: transitional care medicine. The case reviews of two of these patients are described. Patient 1 was a 23-year-old man with hereditary pancreatitis. His genetic condition resulted in the need for pancreatic splenectomy and removal of part of his small bowel, resulting in insulin-dependent diabetes and malnutrition...

This article describes single-retainer resin-bonded fixed dental prostheses (RBFDPs) as an excellent alternative to orthodontic space closure or tooth replacement with implants or conventional fixed dental prostheses for congenitally and traumatically missing anterior teeth. Although the treatment with RBFDPs is technique sensitive, it is extremely reliable given a correct indication and adequate adhesive procedures.

BACKGROUND: Numerous publications have reported on migraines misdiagnosed as endodontic pathologies. However, reports on the effect that concurrent migraine and endodontic pathology can have on each other and how their respective treatments can also affect each other are limited. CLINICAL PRESENTATION: Two cases are reported that presented with both migraine and periapical pathology. Patient 1 underwent root canal treatment, which partially alleviated both the migraine and odontalgia...

Tooth-colored resin-based bracket bonding agents are used to fix orthodontic brackets to teeth as inconspicuously as possible. However, after debonding the brackets, these tooth-colored bonding remnants remain on the tooth surface and must be removed to prevent adverse sequelae. Various techniques can be used, all of which cause varying damage to the tooth structure, as the transition between composite and enamel is visually difficult to detect. With the fluorescence-aided identification technique (FIT) presented here, the fluorescent properties of new orthodontic composites are used for visualization, thereby allowing the tooth-colored but fluorescent resin-based bracket bonding remnants to be removed under direct view quickly and without damaging the tooth...
