As patients in a dental or medical context, persons find themselves in a vulnerable, exceptional psychological and physical situation, in which the solution-oriented regulation of emotions requires mindful, systemic communication. This review describes typical placebo and nocebo effects in verbal, paraverbal and non-verbal communication and their impact on patients and their relationship with dental or medical professionals. In addition, a training curriculum for second-year undergraduate dental master’s students is described, that not only provides students with the necessary competences for solution-oriented systemic communication, but also enables them to experience its effectiveness in the clinical context.

This study explored the clinical and radiological outcomes after autologous premolar and wisdom tooth transplantation, with a focus on periodontal status. A systematic search was conducted using all relevant databases up to April 5, 2024. The inclusion criteria were as follows: a) human participants, b) a sample size of at least five autotransplanted teeth, c) molar or premolar transplants, d) English language use, and e) at least 1 year of follow-up. The following parameters were assessed: probing pocket depth, recession, tooth mobility, ankylosis, bone level, and tooth loss. Our search identified 466 records, and after our selection process, 25 articles were suitable for analysis, with a total of 3732 teeth (569 premolars and 350 molars) with a mean follow-up duration of 6.1 years. The 10-year survival rate of autologous tooth transplants ranged from 33.8% to 100%, and the mean complication rates of root resorption and ankylosis were 8.9% (13 studies) and 14.0% (10 studies), respectively. Periodontal complications such as periradicular radiolucency, periodontal defects, and attachment loss occurred in less than 10% of patients. The premolars exhibited superior clinical and radiological outcomes compared with the molars. In conclusion, the survival rate and periodontal status after autologous tooth transplantation (ATT) of premolars and molars were consistent with those of traditional dental implants. Therefore, autotransplantation may be considered in cases where dental implants are indicated. As specific reports on periodontal complications are scarce, further research is warranted to identify the specific factors associated with periodontal complications in autologous transplant recipients.

Cervical lymphadenopathy can indicate a range of diseases, including infections, inflammation, and neoplastic processes. Accurate diagnosis is crucial for identifying the underlying cause and determining appropriate treatment. Diagnostic procedures include clinical examination, ultrasound, fine needle aspiration, biopsy, and imaging techniques. While conventional imaging methods such as X-ray and computed tomography (CT) have proven useful, they exhibit limitations in sensitivity and specificity, especially for soft tissue structures. Magnetic resonance imaging (MRI) provides superior soft tissue contrast, offering additional critical information for differential diagnosis. This article presents a case study of a 29-year-old male with a cervical mass. Advanced dental MRI protocols, including DESS, SPACE-SPAIR, and SPACE-STIR sequences, have significantly enhanced the imaging capabilities of the den-tomaxillofacial region, enabling the generation of high-resolution images of both hard and soft tissues. Especially, MR OPGs have demonstrated the capacity to identify early signs of potential pathology. These protocols have the potential to enhance early detection, thereby con-tributing to accurate diagnosis and effective treatment planning.

Soft tissue lesions are among the most prevalent forms of tumors or tumor-like alterations within the oral cavity. They exhibit a wide spectrum of characteristics, ranging from benign, noninvasive lesions to malignant tumors, which collectively present a diagnostic challenge. A 67-year-old patient presented with an incidental finding of induration on the right cheek during dental hygiene. The intraoral examination revealed a soft, non-tender swelling measuring 20 mm in diameter. The sensitivity and percussion tests for the teeth in the fourth quadrant yielded unremarkable results. Panoramic radiography (OPG) revealed tip-ping of the premolars and an unclear apical finding in region 44. Cone-beam computed tomography (CBCT) revealed a sharply defined, lobulated hypodense lesion in the right buccal area. To clarify the diagnosis and optimize perioperative management, a 3 Tesla dental magnetic resonance imaging (MRI) scan was performed. This identified a 23×6×23 mm lipoma along the right mandibular ramus, causing detachment of the buccinator and de-pressor anguli oris muscles. A cinematic rendering reconstruction derived from the MRI data facilitated enhanced visualization for preoperative planning. The surgical excision was performed under local anesthesia, resulting in the successful removal of the neoplasm while preserving the mental nerve and submandibular gland. Histo-pathology confirmed the presence of a lobulated mature cell lipoma. The patient exhibited no complications during the removal of the sutures, with complete wound healing and no recurrence observed. This article highlights the efficacy of advanced MRI diagnostics and post-processing techniques in the management of ambiguous soft tissue neoplasms.

A scoping review investigated the effectiveness of different communicative interventions for patients with dementia. It demonstrated that communication between caregivers and dementia patients is improved by music, multisensory stimulation, and communication training. As a result agitation, mania, fear, anger and corrective touching are reduced, and fluency, spontaneous speech, eye contact, smiling and affective touching are enhanced. The recommendations, summarized in a fact sheet, also contribute to improved therapeutic decision making with bystanders and oral health of people with dementia.

Endodontic irrigation protocols are not only used to clean and disinfect the root canal system, but also to condition the canal wall dentine for subsequent root filling. In this study we tested whether a final irrigation step with saline solution or 80% ethanol improved root canal sealabilty by two popular sealers, an epoxy resin (AH Plus) and a hydraulic calcium silicate cement-based product (BioRoot RCS). Root canals in extracted single-rooted human teeth were instrumented and filled with a matched gutta-percha cone and sealer. During instrumentation and prior to root filling, sealer-specific irrigation protocols were applied. These involved a combined sodium hypochlorite/1-hydroxyethylidene-1,1-diphosphonic acid application, which was followed by irrigation with ethylenediaminetetraacetic acid (EDTA) for AH Plus. Protocols were followed by a 5-ml ultimate rinse with saline solution or 80% ethanol. No such final rinse was the control (N = 9). Canals were then dried with matched paper points. One week after root filling and storage of the teeth at 37°C in a humid environment, Rhodamine B was used to trace leakage. Two-way ANOVA revealed that the type of sealer had a significant (P < 0.05) impact on apical dye penetration while the final rinse did not (P > 0.05). AH Plus provided the slightly better seal (P < 0.05). Leakage occurred between the sealer and the dentin with AH Plus, and between the sealer-to-dentin as well as the sealer-to-gutta-percha interface with BioRoot RCS. In summary and under current conditions, there was no benefit from applying saline or ethanol as an ultimate rinsing solution prior to drying the canal with matched paper points.

Numerous technical advances in magnetic resonance imaging have opened up promising new approaches in dentomaxillofacial radiology in recent years. With its ability to simultaneously visualize soft and hard tissues, MRI has the potential to become an innovative method for accurate diagnosis and planning of dental implants. Dental MRI is already a valuable and useful complement to conventional X-ray imaging techniques and could further minimize the risks of surgery by optimizing existing treatment protocols. Considering current efforts in dentistry to reduce radiation exposure and take a further step toward personalized oral diagnostics that consider patient-specific factors, this article reviews the capabilities of dentomaxillofacial MR imaging in implant surgery. It highlights the various applications of MRI in dental implant surgery and evaluates both the benefits and the clinical challenges. Overall, considering the specific indications and limitations of MR sequences, dental MRI represents a further significant advance in individualized treatment planning in dentistry. It allows consideration of parameters not visualized by conventional imaging techniques and is particularly useful for evaluating surgically relevant parameters, especially those related to soft tissue.

Das kongenitale Fehlen von Milchzähnen ist ein Problem. Mit Ausnahme der dritten Molaren sind die zweiten Unterkiefer-Prämolaren (2.5-4.5%) am häufigsten betroffen. Der Erhalt des Vorgängerzahnes ist eine Möglichkeit, den Platz zu erhalten und die definitive prothetische Entscheidung hinauszuzögern. Eine Literaturübersicht fand pathologiefreie Überlebensraten von 82-89 % über einen Zeitraum von 5-13 Jahren. Neben Karies und Gingivitis stellen eine Infraokklusion oder Wurzelresorption typische biologische Komplikationen dar.

The masticatory organ is at the center of dental practice. Tooth loss, regarded as an organ failure, is a core dispute in our profession, as it more often than not does not happen spon-taneously but is influenced by the dentist's treatment plan. Despite the prosthetic possibili-ties of tooth replacement, efforts should be made to preserve as many teeth as possible. Decisions between tooth preservation and extraction are complex and have far-reaching consequences. This article discusses this problem using a clinical case study of a 43-year-old female patient with pronounced localized periodontitis. After a comprehensive diagnosis and treatment planning, a daring regenerative therapy was carried out to try to preserve the tooth. The case shows that even seemingly hopeless teeth can be successfully treated syn-chronously using modern therapeutic approaches. Initial literature data supports the possi-bility of preserving severely compromised teeth in the long term in compliant patients. An integrative treatment approach based on individual patient factors and modern regenerative techniques may well be a viable alternative to tooth extraction and prosthetic restoration, albeit not inexpensive and uncomplicated. This communication emphasizes the need for precise diagnostics, a comprehensive treatment plan, and honest communication with pa-tients about the prospects of success and possible risks, and highlights the strengths of con-sistent tooth preservation.
