Dental Anxiety Among Students of the University of Rijeka, Croatia.

Objectives: Dental anxiety is a common problem and a great challenge for many patients, but also for dentists - the treatment of anxious patients is considered to be one of the most stressful situations for dentists. The aim of this study was to evaluate the prevalence of dental anxiety among the students of the University of Rijeka and to detect possible differences in the level of anxiety among students of different study programs. Participants and methods: This cross-sectional study included 290 students from different faculties of the University of Rijeka (Faculty of Law, Faculty of Humanities and Social Sciences, Faculty of Engineering, Faculty of Medicine, Faculty of Dental Medicine), 73 (25.17%) male and 217 (74.83%) female students. The study was conducted online via The Modified Dental Anxiety Scale (MDAS) in 2020 and sampling was based on voluntary responses. The Student's t-test and ANOVA were used to compare differences in MDAS scores among students. Results: There is a significant difference in dental anxiety levels between students from the Faculty of Humanities and Social Sciences and Faculty of Dental Medicine (MDAS=11.32±4.11, MDAS=8.84±3.03, p=0.01), and also between students from the Faculty of Law and Faculty of Dental Medicine (MDAS=11.47±4.64, MDAS=8.84±3.03, p <0.01). Conclusions: This research showed that non-dental students have a higher level of dental anxiety than dental students. Sufficient knowledge of dental and oral health could potentially overcome dental fear and anxiety. Therefore, there is a need to provide additional dental education throughout the university curriculum.

Postoperative Morbidity after Dental Treatment under General Anesthesia in Children with and without Disabilities.

Background and Objectives: General anesthesia induces reversible unconsciousness, eliminating sensation and enabling painless medical procedures. Vital for dental care, it addresses patients with medical conditions, those needing extensive procedures, and those unable to cooperate due to fear. Dental care for patients with disabilities is a significant unmet need, with studies showing increased oral disease prevalence. This research aims to analyze postoperative morbidity both in healthy and disabled children undergoing dental procedures under general anesthesia. Materials and Methods: This study involved 96 children aged 3 to 15 with dental caries. Two groups were formed: the control group (CTL) (52.94%) included healthy patients requiring general anesthesia due to unsatisfactory cooperation, and the other group included children with physical or intellectual disabilities (CD) (47.96%). Postoperative complications were monitored 1 h after the procedure and 1, 3, 7, and 14 days after the procedure by contacting parents/caregivers by phone. The intensity of postoperative pain was assessed using the Wong-Baker faces pain rating scale. General anesthesia was conducted following a standardized protocol for dental procedures. Results: CTL patients complained more often about postoperative pain 1 h after the procedure (p = 0.03). One day after the procedure, oral bleeding (p = 0.04), fever (p = 0.009), and diarrhea (p = 0.037) occurred more often in CD. In the same period, sore throat appeared more often in CTL (p = 0.036). Three days after the dental treatment, there were statistically significant increases in the occurrence of agitation (p = 0.043) and constipation (p = 0.043) in CD. Seven days later, CD demonstrated a higher occurrence of agitation (p = 0.037). According to the Wong-Baker faces pain rating scale, CTL experienced more frequent and intense pain. Conclusions: CD more frequently reported complications like oral bleeding, fever, and diarrhea. In contrast, the CTL group more often reported pain-related symptoms. The conclusion underscores the need for a pain control protocol for CD and emphasizes the importance of frequent monitoring to prevent unwanted consequences during tooth restoration under general anesthesia.

The Role of Family Factors in the Development of Dental Anxiety in Children.

Background and Objectives: In the literature, the influence of parents who suffer from dental anxiety and a previous unpleasant experience at the dentist are cited as the two most common causes of dental anxiety in children. The aim of this study is to investigate the relationship between socioeconomic factors and the development of dental anxiety in children aged 9 to 12 years. Materials and Methods: A total of 131 children and their accompanying parents/guardians participated in the cross-sectional study. The children were divided into an experimental group, which visited a specialised office for paediatric and preventive dentistry for the examination, and a control group, which visited a primary care dental office. During the visit, the children completed questionnaires on dental anxiety (CFSS-DS). Parents completed a socioeconomic questionnaire and a dental anxiety questionnaire for adults (CDAS). Results: The results showed a statistically significant positive predictor: parental dental anxiety as measured by the CDAS. In addition, the t-test showed that children who visited a specialised dental office did not show a statistically significant increase in dental anxiety compared to children who visited a primary care dental office. Conclusions: With this study, we confirm the influence of parental dental anxiety on the development of dental anxiety in children. The socioeconomic status of the family and the type of dental office do not play a statistically significant role in the development of dental anxiety in children.

Bennett Angle, Condylar and Jaw Movements in Asymptomatic Athletes with a History of a Blow to One Side of the Mandibula.

Sports activities may induce long-lasting changes in mandibular trajectories. The aim was to compare condylar and mandibular movements in athletes with orofacial injuries with values measured in non-injured athletes. The group of 132 athletes without mandibular injury included asymptomatic athletes with a history of a blow to the right side (N = 43) and the group included asymptomatic athletes with a history of a blow to the left side (N = 41) of the mandible. The injured athletes suffered from stiffness/pain and/or limitation of jaw movements. The symptoms disappeared shortly after the injury. Athletes with a history of injury have smaller mean values of Bennett angle on the side of impact, and Bennett angle on the opposite side is greater than the mean found in non-injured athletes. Significantly smaller Bennett angle values in athletes with a history of a blow to one side of the mandible are due to the adaptability of the orofacial system. The larger Bennett angle on the opposite side of the injury is also due to the adaptive mechanism of the TMJ. Clinical Relevance: An individualized approach to TMJ values is mandatory in restorative procedures in every patient, especially in patients with a history of trauma to the orofacial system.

Evaluation of Bioactive Glass Treatment for Dentin Hypersensitivity: A Systematic Review.

The aim of this systematic review is to compare home and office desensitizers containing bioactive glass with control groups in randomized controlled trials (RCT) conducted between 2018 and 2022. According to PRISMA guidelines, three electronic databases (Scopus, PubMed, and Cochrane Library) were searched for published scientific articles in October 2022. RCT with adult participants with dentin hypersensitivity (DH) diagnosed by evaporative, mechanical, or thermal stimulation, with a follow-up period and quantified pain assessment were included in the study. Studies that reported DH due to tooth restoration, crown preparation, bleaching, or periodontal surgery or used bioactive glass-ceramics were excluded. The quality of the studies was assessed using version 2 of the Cochrane Risk-of-Bias Tool for randomized studies (RoB 2 tool). Articles that were duplicative or unrelated to this study were excluded. Nine articles were selected for full-text evaluation, whereas two articles were rejected. The remaining seven reports were included in this review. The calcium sodium phosphosilicate group (CSPS) was not significantly different from the positive control groups. Compared with the control groups, fluoro calcium phosphosilicate (FCPS) may be the most effective long-term treatment option. In terms of DH symptom reduction, the FCPS group performed better than the CSPS group. CSPS at a concentration of 5-15% and FCPS at a concentration of 5% are effective in treating DH in adult participants.
