The COVID-19 pandemic has severely affected the human population by revealing many health problems, including within the oral cavity. This systematic review was designed to answer the question “Is there a relationship between oral manifestations and SARS-CoV-2 infection?”. Following the inclusion and exclusion criteria, twenty-seven studies were included (according to PRISMA statement guidelines). Based on the meta-analysis, nearly two-thirds of the SARS-CoV-2 positive patients reported oral symptoms, in particular taste alterations, xerostomia and ulcerations (54.73% [95% CI: 46.28–63.04%], 37.58% [95% CI: 26.35–49.53%], and 21.43% [95% CI: 13.17–31.06%], respectively). In conclusion, despite the conducted systematic review, the increased prevalence of oral manifestations in SARS-CoV-2 infection cannot be clearly established due to the possible association of other factors, e.g., individual or environmental factors.

Composite materials are widely used in dentistry for direct tooth restorations. However, they are highly sensitive to the working technique employed during the restorative procedure. Even minor procedural errors can have a significant impact on the quality including the longevity of the restoration. Hence the aim of this study was to determine the material preferences and analyse the clinical problems associated with direct composite restorations in a cohort of dentists. A 20-item online questionnaire was created in English and administered 1830 general dentists and specialists in 13 countries. The first section of the questionnaire included four questions to elicit demographic data, and the second section comprised 16 questions focused on material preferences for conservative restorations, durability of composite restorations, and the most challenging stages the dentists faced during the composite restorative procedures. Respondents decided most often to use composite materials for the tooth restorations (OR 997.4, 95% CI 233.8-4254.8, P value <.001). Most respondents indicated that the durability of composite restorations was approximately 7 to 10 years (41.5%). Among the factors affecting durability, maintenance of a dry cavity was the most often reported reason (47.1%) and the foremost challenge faced by dentists (61.0%) during the composite restorative procedures. Our study confirmed that resin-based composites are the most popular material for direct restoration in many countries. Although working with this material is difficult and involves multiple steps, maintaining a dry cavity during bonding, and material application may affect the therapeutic success and durability of these restorations. Clinicians need to be attentive to this issue and be prepared to adapt their decision-making and consider opting for alternative restorative materials, if appropriate.

Resin-based composites (RBCs) evolved into favoured materials for teeth restorations, marking a significant change in dental practice. Despite many advantages, RBCs exhibit various limitations in their physical and chemical properties. Therefore, we assessed the dentists' awareness of possible complications after direct composite restorations and their opinions about this material. The online questionnaire was created in English in May 2023. A 16-item survey was dedicated to general dentists and specialists. The first section included four questions related to demographic characteristics. The second section comprised twelve questions and focused on awareness of potential side effects of composite restorations, the most crucial advantages and disadvantages of composite resins, and the frequency of experienced clinical complications after the application of composite materials. A total of 1830 dentists from 13 countries took part in the survey. Dentists most often declared awareness of low adhesion to the dentine (77.5%) and, most rarely, solubility in oral fluids (42.6%). Aesthetics was identified as the main advantage of composite fillings (79%), followed by the possibility of repair (59%) and adhesion to enamel (57%). Polymerisation shrinkage was a major disadvantage for most countries (70% overall). Analysing the declared potential clinical complications for all countries, statistically significant findings were obtained for marginal discolouration (OR=2.982, 95%CI:1.321-6.730, p-value=0.009) and borderline significance for secondary caries (OR=1.814, 95%CI:0.964-3.415, p-value=0.065). Dentists value aesthetics and repairability but are aware of shrinkage and experience discolouration. The issue of toxicity and solubility seems to be the least known to dentists. Dentists should use RBCs with critical caution due to possible side effects. Despite the undoubted aesthetics of direct composite restorations, it is necessary to remember potential clinical complications such as marginal discolouration or secondary caries.

Introduction and aim. The purpose of this study was to compare different Computerized-Controlled Local Anesthetic Delivery (CCLAD) systems to one another in addition to the conventional syringe. Material and method. The CCLAD systems chosen for this study are the Quicksleeper, SleeperOne, and The Wand. These are discussed in categorical objectives, including the following: duration of anesthesia, analgesic effect, locality; anxiolytic effect; advantages and disadvantages; comfort and safety of use; limitations. Analysis of the literature. The research found that many factors influence the effectiveness of dental injections, and the CCLAD systems are designed to reduce the ones that cause negative experiences. The injection systems are unique in their descriptions but show many similarities. Conclusion. The research concluded that each device has its advantages and disadvantages and that its efficiency depends on outlying factors, independent of the injection system used.

Patients with Down Syndrome (DS) commonly exhibit various anomalies in the masticatory organ and oral cavity. This paper aims to consolidate information regarding oral health challenges faced by individuals with DS, along with strategies employed for their management and care. Our review, conducted via PubMed and Scopus, spanned the period from January 1977 to December 2023. It included original research articles and comprehensive reviews focusing on both pediatric and adult populations. The paper analyzes 71 articles, categorizing them into six sections: oro-facial problems, tooth conditions, dental and skeletal age, dental caries, periodontal diseases, swallowing, masticatory muscles, salivation, behavior management, physical therapy, and early intervention. Understanding oral health issues in individuals with DS is crucial for providing tailored dental care and treatment planning. Regular dental assessments, early intervention strategies such as physiotherapy and behavioral management, and a collaborative approach involving oral health professionals, caregivers, and the individuals themselves are critical to preventing oral health issues and improving overall health and well-being in people with DS.
