The objective of this systematic literature review was to investigate the effect of Coca-Cola on the properties and, more generally, on the integrity of direct dental filling materials. In addition, it aimed to highlight the importance of dietary behaviour in dentistry and, in this context, to identify tangible strategies for action in routine clinical practice. An electronic search was conducted between January 2022 and July 2024. It included the PubMed, Livivo, Directory of Open Access Journals, and ScienceDirect databases, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and the International Clinical Trials Registry Platform, as well as grey literature databases and ResearchGate, further supplemented by the references of the included study articles. In accordance with the predefined inclusion and exclusion criteria, a total of 92 experimental study articles were included in the review, focusing the optical, mechanical, chemical, and biological material properties, but also regarding the surface characteristics and the interface between the restoration and the tooth structure. Given the considerable heterogeneity and in vitro design of the included study articles, it can be demonstrated that Coca-Cola has an effect on the materials under consideration. However, the extent of this influence is highly dependent on the specific restorative materials and the methodology used. The determining factors are accumulated contact time and frequency of exposure, and these factors therefore serve as a critical starting point for preventive measures.

Periodontitis leads to a destruction of the tooth-supporting apparatus, which untreated may end up in tooth-loss. Key factor in the pathogenesis of periodontitis is the host immune response, genetic predisposition, and lifestyle factors (such as smoking, stress, and diabetes), all of which influence disease severity. Periodontitis is more common in men than women, this fact may point out that gender may have an influence on periodontitis. In addition, the incidence and severity seem to have a gender predilection with the incidence and severity of periodontal disease appearing to be greater in males than in females. The purpose of this narrative review was to summarize the existing literature on influence of gender in periodontology. The review included German and English articles and aimed to identify any gender differences in periodontitis. The World Health Organization (WHO) defines gender as the socially constructed characteristics, norms, behaviors and roles associated with being a woman, man, girl or boy, and the relationships between them. The topic of "gender" is not a new topic in dentistry. However, existing studies are relatively limited and further research is needed to improve our understanding of this topic. In fact, understanding gender and gender differences in oral health may be valuable for improving the effectiveness of preventive and therapeutic interventions. By recognizing and addressing these differences, healthcare professionals can tailor their approaches to better address the specific needs and challenges of individuals of different genders. This can help improve overall oral health outcomes.

Due to effective preventive measures and advanced techniques in operative dentistry, tooth loss occurs later in life and implant restorations have become a common solution for replacement of missing teeth. Therefore, the use of removable dental prostheses (RDPs) is expected to decline over time. This study aims to evaluate the expected decrease in the production of RDPs in Swiss dental laboratories over the past decade. From 2012 to 2022, two indicators of prostheses production were examined: the number of dental laboratories (DL) and dental technicians in Switzerland, and the import and sale rates of denture teeth. 85 DL participated in a survey and indicated their perception regarding market trends. Finally, in-depth data collection was conducted in 16 DL in French-speaking Switzerland to gather the production of various types of RDPs over the last ten years. Over the observation period, the number of DL significantly decreased (p<0.05), while the decrease in dental technicians was less pronounced. The overall quantity of prosthetic teeth imported into Switzerland or sold by Curaden AG witnessed a significant decline (p<0.05). Survey findings revealed inconsistent perspectives from the respondents on the profession's development, despite a tendency suggesting a decline in complete prostheses and an increase in partial or hybrid removable prostheses (p<0.01). Except for a decline in the number of chrome-cast partial prosthesis manufactured (p=0.04), no clear trend was observed in the 16 DL. Despite lower import rates of denture teeth and a perceived shift in denture type, the overall production of RDPs seems to remain substantial.

Dental magnetic resonance imaging (MRI) has long been perceived as overly complex, costly, and limited in availability. Despite the numerous advantages of this radiation-free, non-invasive procedure for soft tissue diagnostics in the head and neck region, its imaging capabilities for hard tissue, such as bones and teeth, have thus far remained limited in comparison to conventional X-ray technology. In recent years, however, technological advances have led to a notable enhancement in the image quality and the range of applications of dental MRI. This article presents a comprehensive review of the current literature on the utilization of dental MRI for dentomaxillofacial conditions. The article focusses on novel MRI protocols that have been specifically developed to address the inherent challenges associated with imaging the head and neck region. It also considers the latest technological advances, including innovative coils and the use of low and high-field MR systems. The practical case studies are from the fields of conservative dentistry, prosthodontics, orthodontics, oral surgery, and maxillofacial surgery, demonstrating the theoretical concepts and emphasizing the clinical advantages of dental MRI. In conclusion, dental MRI can be a valuable complement to and, in certain cases, a true alternative to X-ray-based procedures.

Cone beam computed tomography (CBCT) is established in dentistry for about 20 years. Technique evolved and indications clarified since then and since the Swiss consensus guidelines regarding CBCT were published in 2014 and 2015. Therefore, the Swiss association of dentomaxillofacial radiology decided to initiate the process of updating these guidelines by forming a consensus group divided into a core group responsible for the whole process and an approval group responsible for specific clinical matters. The manuscript outlines the revised guidelines in a practical way and is divided along the different specialties and clinical fields of dentistry. In result the guidelines are updated regarding reconstructive dentistry, orthodontics, geriatric dentistry, temporomandibular joint disorders, maxillofacial traumatology, benign and malignant tumors, assessment and detection of dental foci and endodontic infections and apical surgery. Overall, it can be stated that CBCT is utilized more consistently and somewhat broader than ten years ago. Today CBCT is well established and has proven benefits if indicated and analyzed precisely. Therefore, it might very well become more and more standard in dental radiology.

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.
