The aim of this study was to retrospectively summarize all occupational incidents involving sharp objects, including needlestick injuries and scalpel blade cuts, reported among dental personnel and dental students at the University Center for Dental Medicine Basel (UZB) over a 5-year period, from 2019 to 2023. These incidents were documented by the UZB Human Resources Department. The information recorded included the two groups (dental personnel, i.e. dentists and dental assistants; dental students) as well as the gender and age of the person. The annual incidence ranged from five to 15 for dental personnel and from two to five for dental students. The mean incidence over the 5-year period was 4.4%. No statistically significant differences were observed between years (p = 0.48), sexes (p = 0.57), or groups (p = 0.99). The highest pooled annual incidence was observed in 2020 with a value of 5.8%. The highest incidence for dental personnel was 6.4% in 2020 and 6.4% in 2019 for dental students. Given the regular occurrence of sharp injuries, it is necessary to implement additional protective measures to further reduce the incidence of such accidents.

External cervical resorptions (ECRs) are challenging dental hard tissue lesions. They are frequently missed due to their asymptomatic progression. Three-dimensional imaging and increased awareness within the dental community have likely contributed to the observed rise in ECR prevalence over the recent years. While the exact etiology of ECR remains unclear, numerous risk factors have been identified, encompassing both physical and chemical factors. However, idiopathic cases have also been documented. Literature highlights the propensity of ECRs to occur in anterior teeth and molars, often linked to prior orthodontic treatments and picked up by bitewing or periapical radiographs. However, in cases involving canines, early diagnosis is frequently missed, and lesions are typically discovered at a later stage only, when clinical signs and symptoms manifest. We present several cases in this narrative review, including a case report on a 59-year-old patient presenting with an ECR in the maxillary left canine (tooth 23), decades after orthodontic treatment. The lesion was successfully managed using a combination of endodontic and surgical treatment. Despite the advanced stage of resorption, the tooth was preserved. Given ECR's slow progression and frequent late clinical detection, additional radiographic monitoring of front and canine teeth can be recommended for patients with predisposing factors, such as a history of orthodontic treatment or trauma. This proactive approach can facilitate earlier diagnosis and timely intervention, improving outcomes for affected teeth.

This study evaluated the effect of periodontal dressing on the healing of gingival tissue following external bevel gingivectomy. Participants aged 18 to 60 years indicated for external bevel gingivectomy in the anterior maxillary with a band of keratinized gingiva greater than 3 mm were enrolled. The patients underwent gingivectomy using the external bevel surgical technique on the vestibular gingiva of sextant 2. Subsequently, the gingival epithelium was removed. Participants were randomized into two groups: with or without periodontal dressing. Gingival index, healing area, presence of visible plaque, and patient satisfaction were assessed. Evaluations were conducted at baseline, 7, 14, and 21 days after the procedure. Data were analyzed using the Chi-Square test and Mann-Whitney test. The sample included three men (12%) and 22 women (88%). Thirteen patients (52%) were allocated to the periodontal dressing group and 12 (48%) to the no-dressing group. There was no statistically significant difference between groups in terms of sex (p = 0.531), age (p = 0.682), gingival index (p = 0.400), pain level (p = 0.799), healing area (p = 0.277), and satisfaction with the outcome (p = 0.265). Within-group analysis showed a significant reduction in the healing area (p < 0.001) for both groups. The periodontal dressing does not affect the healing of gingivectomy wounds.

Autotransplantation of immature third molars is an effective treatment option, offering high success rates, minimal complications, and notable improvements in occlusal function and dental aesthetics. This study aims to review and evaluate the available evidence specifically on the survival and success rates of immature autotransplanted third molars and to identify prognostic factors that influence these outcomes. A comprehensive search was conducted in the Elsevier Journals (ScienceDirect), MEDLINE (PubMed), and Dentistry & Oral Sciences Source (EBSCOhost) databases up to May 2024. Risk of bias within studies was asse ssed with the CASP guidelines. Nine studies met the inclusion criteria for qualitative and quantitative analysis. The pooled survival rate was consistently high across studies, estimated at 91.867% (95% CI: 85.058% to 96.741%), while the success rate, though slightly lower, remained substantial at 90.162% (95% CI: 79.813% to 97.067%). Key prognostic factors identified include the developmental stage of the donor teeth (Moorrees stages from R ¼  to Rc), showing enhanced success due to better potential for pulp revascularization and continued root growth. Additionally, innovative techniques, including advanced methods like computer-aided rapid prototyping (CARP) and platelet-rich plasma (PRP), were found to positively impact healing and integration. Fixation methods also played a role, as excessive rigid fixation was linked to higher rates of ankylosis and inflammatory root resorption. Future research should prioritize recipient site and donor tooth characteristics, standardized success criteria, extended follow-up periods, and refined treatment protocols to enhance predictability and long-term outcomes in teeth autotransplantation.

The aim of this retrospective descriptive study was to identify the treatment frequency of prisoners and the associated need for dental treatment, as well as to analyse the associations between the DMFT index, general health conditions (mental health) and health behaviour (cigarette smoking). For this purpose, the medical records (secondary data) from 2018-2020 of 317 inmates receiving dental treatment from two Basel prisons were examined, categorized and statistically evaluated using linear regression models (RECORD 1.1, 1.2). At the time of the medical history, 87.1% of the inmates were taking at least one medication, 47.9% of them psychotropic drugs and 52.7% analgesics. 5.5% had a hepatitis C virus (HCV) infection. Opioid use correlated with HCV infection: 24.5% of opioid users (m/f) were also HCV+. Teeth had to be removed in 58.7% of inmates. The DMFT index was 1.85 times higher in smokers than in non-smokers. With each pack of cigarettes per day, the DMFT index increased 1.44-fold. The DMFT index in prisoners with mental illness was 1.5 times higher. Possible approaches to improve general and dental health include drug prevention, withdrawal therapy, sports promotion, dental health education and the provision of oral hygiene products. It is recommended that further studies be conducted with comprehensive examinations of inmates.

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.
