Obstructive sleep apnea syndrome (OSAS) is the most common breathing-related sleep disorder. It is characterized by recurrent episodes of partial or complete airway obstruction during sleep, resulting in a reduction in or the total cessation of airflow, despite ongoing respiratory efforts, leading to oxygen desaturation and arousal. The purpose of this literature review is to evaluate the most common characteristics of this pathology, as well as to investigate the most effective treatment options, providing an update on the management of OSA patients.

The concept of machines learning and acting like humans is what is meant by the phrase “artificial intelligence” (AI). Several branches of dentistry are increasingly relying on artificial intelligence (AI) tools. The literature usually focuses on AI models. These AI models have been used to detect and diagnose a wide range of conditions, including, but not limited to, dental caries, vertical root fractures, apical lesions, diseases of the salivary glands, maxillary sinusitis, maxillofacial cysts, cervical lymph node metastasis, osteoporosis, cancerous lesions, alveolar bone loss, the need for orthodontic extractions or treatments, cephalometric analysis, age and gender determination, and more. The primary contemporary applications of AI in the dental field are in undergraduate teaching and research. Before these methods can be used in everyday dentistry, however, the underlying technology and user interfaces need to be refined.

As an alternative to regenerative therapies, numerous authors have recently proposed bringing back subperiosteal implants. The aim of the study was to present our clinical experience with a subperiosteal jaw implant that needs minimal bone preparation and enables the rapid implantation of prosthetic teeth in edentulous, atrophic alveolar bone. The research included 36 complete or partial edentulous patients (61 subperiostal implants) over a period of 6 years. To create the patient-specific subperiostal implants design, DentalCAD 3.0 Galway software (exocad GmbH, Darmstadt, Germany) was used and fabricated with a Mysint 100 (Sisma S.p.A., Piovene Rocchette, Italy) by titanium alloy powder. The results showed that only 9 of the 36 cases were successful at 6-year follow-up, while 27 cases had complications, including exposure of the metal frame (early or delayed), mobility of the device prior to the first 4–6 months, and late mobility due to recurrent infections and progressive structure exposure; 1 case failed for reasons unrelated to the device. This study indicated that the prudent application of fully customized subperiosteal jaw implants is a dependable alternative for the dental rehabilitation of atrophic edentulous cases that necessitate bone grafts for traditional fixed dental implant solutions.

The biomedical applications of silicones are countless due to their outstanding properties. In dentistry, silicone for maxillofacial and plastic surgery has become indispensable, from both physiological and aesthetic points of view. In this mini-review, silicone materials for dentistry and facial prostheses are discussed, focusing on their properties and alterations when exposed for long periods to different environments. A significant number of studies reported in the literature have been conducted in vitro, mimicking some of the main degradative factors which have been identified as triggers for discoloration and deterioration of the mechanical properties. Among these, in artificial aging and accelerated natural aging studies, UV radiation is considered the most important. Other weathering factors, biological contamination, and disinfection agents may have dramatic effects as well. Several general properties of silicones are described at the beginning, with a focus on biocompatibility, cross-linking mechanisms, and applications in dentistry and maxillofacial prosthetics. We discuss the ongoing cross-linking and/or possible exudation after manufacturing, which also affects the stability of the prosthesis over time, and possibly the patient. Next, the main environmental factors that affect the prostheses in service are presented, including the role of cigarettes smoke, which has been discussed very little so far. A few aspects, such as biofilm formation, its negative effects, and proposed solutions to overcome this phenomenon regarding silicones, are also described. We conclude by proposing a set of topics for future research and development based on the gaps that have been identified in the literature. Although silicones are probably irreplaceable in maxillofacial prosthetics, improvements in terms of base materials, additives, surface treatments, and maintenance are possible and necessary for long-lasting and safer prostheses.

Background and Objectives: Dental anxiety can hinder both treatment delivery and dental education. Few studies have examined this issue among Romanian dental students. This study assessed the prevalence, intensity, and main procedural triggers of dental anxiety, with a focus on experiences related to local anesthesia. Methods: A cross-sectional survey was conducted (January–May 2024) among 122 fourth-year students using the validated Romanian version of the Modified Dental Anxiety Scale (MDAS) and additional items on demographics, prior anesthesia and perceived complications. Data analysis included descriptive statistics, chi-square tests, and t-tests. Results: Overall, 21.3% of respondents scored in the low anxiety range, 75.4% in the moderate range, and 3.3% in the severe range (MDAS ≥ 19). No significant gender differences were identified (p > 0.05). Injections with local anesthetic were rated as the most distressing procedure, followed by drilling, whereas scaling was reported as least stressful. The majority (86.9%) had undergone previous local anesthesia, with very few adverse events recalled. Conclusions: Romanian dental students reported moderate dental anxiety overall, with local anesthesia injections as the main trigger. The lack of gender differences points to a potential buffering effect of clinical exposure. Incorporating structured anxiety management into dental curricula may enhance both student well-being and patient care.

Background and Objectives: Anxiety in dental settings can hinder both treatment delivery and educational experiences. For students in training, fear of specific procedures, particularly local anesthesia, may persist despite progressive clinical exposure. Evidence on this issue among Romanian dental students is scarce. This study aimed to assess the prevalence, intensity, and main procedural triggers of dental anxiety among Romanian dental students, with a specific focus on experiences related to local anesthesia. Methods: A cross-sectional study was conducted between January and May 2024 on 122 fourth-year students (79 females, 43 males) enrolled at the Faculty of Dental Medicine, “Grigore T. Popa” University of Medicine and Pharmacy, Iași, Romania. Participants completed the validated Romanian version of the Modified Dental Anxiety Scale (MDAS) and answered additional items on demographic factors, prior exposure to local anesthesia, perceived complications, and procedures most likely to trigger anxiety. Data analysis included descriptive statistics, chi-square tests, and t-tests. Results: Overall, 21.3% of respondents scored in the low anxiety range, 75.4% in the moderate range, and 3.3% in the severe range (MDAS ≥19). No significant gender differences were identified (p > 0.05). Injections with local anesthetic were rated as the most distressing procedure (mean 2.29 ± 1.02), followed by drilling, whereas scaling was reported as least stressful. The majority (86.9%) had undergone previous local anesthesia, with very few adverse events recalled. Conclusions: The findings show that Romanian dental students experience mostly moderate levels of anxiety, with local anesthesia injections remaining the dominant trigger. The lack of gender differences points to a potential buffering effect of clinical exposure. These results support the inclusion of structured anxiety management within dental education and provide context-specific data for comparison with international cohorts.
