A one-year prospective human intervention study was performed to examine the effects of fermented lingonberry juice (FLJ), used as a mouthwash for six months, on salivary parameters. A total of 25 adult participants used 10 mL of FLJ as mouthwash 30 s daily for 6 months in addition to their normal oral homecare routines. Standard oral examinations and gathering of samples were performed at the beginning of the study and after six months and one year. Resting and stimulated saliva secretion rates, resting saliva pH, and stimulated saliva buffering capacity were determined. A questionnaire of participants’ subjective sensations of mouth dryness was also recorded at each timepoint. Fermented lingonberry juice mouthwash had positive effect to all five salivary parameters and were, according to the omnibus test, statistically significant during the study period. Analysis of the subjective dry mouth sensation questionnaires revealed that symptoms of xerostomia decreased due to the use of FLJ. This study revealed that the once-a-day use of FLJ mouthwash had a beneficial, increasing effect on salivary flow rates, buffering capacity, and salivary pH. FLJ thus can be safely used as an adjunctive and beneficial therapy in oral homecare, protecting teeth and oral mucosa, including periodontium, and also relieving dry mouth symptoms.

Purpose: The COVID-19 pandemic altered the methodologies of dental education delivery, resulting in both immediate and more enduring changes. To assess student perceptions of learning effectiveness, graduating dental students from the class of 2020 were surveyed to identify student comfort with technology and content retention, individual motivation and mental focus, and access to resources pertaining to an abrupt transition to a virtual learning didactic seminar approach in March 2020. Methods: a voluntary, 18-question electronic survey was distributed to fourth-year dental students prior to graduation to assess perceptions of learning outcomes and preferences of a virtual seminar format relative to previous in-person didactic seminars experienced. Results: 34 of 80 dental students (42.5%) completed the electronic survey. Comfort and retention of concepts through virtual learning were reported ≥ by 91% and 85% of the respondents, respectively. Increased distractions and multitasking were reported with virtual learning in 56% and 71%, respectively. Desires to have all teaching conducted through virtual learning platforms was reported at 21%. Conclusions: the positive student responses obtained when comparing virtual to in-person seminars in the survey assessment demonstrates the long-term potential for such delivery modalities to be intentionally incorporated into an evolving predoctoral curriculum in a hybrid nature.

This article aimed to set into perspective the unique aspects of trust within the dentist–patient relationship by exploring the literature as well as historical aspects of dentistry in the association between trust/distrust and patient anxiety. In order to characterise this uniqueness, the assumptions for trusting in dentistry are compared and contrasted with other professions using a conceptual analysis. The professions of medicine, sociology, psychology, nursing and dentistry were check listed according to the tenets of a concept analytical approach reported by Hupcey et al., in 2001. Recommendations for patient/person-centred care, as opposed to dentist-centred care, that would improve trust are specified according to the literature. These include empowering patients, practicing active listening, empathy and relationship building that might benefit dental patients in relation to the perceived risks of anxiety or induced pain. It was concluded that global distrust of dominating dentists must give way to person-centred professional strategies so that dentists and patients can tackle their dental anxiety-trust challenges, both in the public’s image of the dental profession and in clinical relationships. Future directions would be to explore incentives for dentists to change to patient/person-centred care.

The Stockholm Studies are a series of investigations started in 1985 and still ongoing. Out of 105,798 inhabitants, aged 30 and 40 years and living in the greater Stockholm area in Sweden, 3273 subjects were randomly selected. Of them, 1676 were clinically examined focusing on oral health. The subjects were then followed up using national population and health registers in order to study associations between oral health parameters and systemic health outcomes and finally death. The 35 years of observation provides unique possibilities to analyze, for example, how periodontitis links to a number of systemic health issues. The results have consequently provided numerous new associations and confirmed earlier observations on how poor oral health is associated with heart diseases and cancer.

Mouthguards (MG) are protective devices that can reduce the risks of facial trauma. However, many athletes do not use them. Additionally, MG wear with coincidental parafunctional activity has not been considered. The aim of this study was to evaluate the stress distribution as a consequence of a direct impact comparing a conventional MG with a novel hybrid appliance (HMG). Using computer-aided design (CAD) software, a human skull was modeled with the teeth inserted into their respective alveolus. The models were divided according to the MG type (conventional or hybrid). The geometries were exported to the computer-aided engineering (CAE) software and the materials were considered isotropic. Fixation was defined at the base of the maxilla. The load was applied using a hockey puck. The total deformation (mm) and the von Mises stress (MPa) results were obtained for the MGs (conventional and hybrid), upper teeth, lower teeth, and maxillary bone. Despite the presence of an MG, it is still possible to observe generated stress in all structures. However, the hybrid design was more efficient than the conventional design in reducing the displacement during the impact and consequently the stress on the upper teeth, lower teeth, and maxillary bone. Higher stress magnitude was more concentrated at the inner portion of the hybrid design than the conventional device. The HMG appliance decreased the stress concentration in the teeth and in the bone, limiting the areas susceptible to injuries to the regions directly impacted by the hockey puck. Although the novel HMG may mitigate injury, some stress will still result, and any possible injury should be evaluated by a dental professional.

Dental student training in clinical communication skills and behavioral aspects of treatment are lauded as clinically meaningful in the dental education literature. However, many dental school curricula still only provide didactic, one-time coursework with multiple choice examination assessment and little or no student skill-activating activities. This article aims to review literature relevant to optimizing clinical communication and behavioral skills in dental education. The review summarizes findings of several relevant reviews and usable models to focus on four themes: (1) special characteristics of dentistry relevant to communication skill needs, (2) essential components of dental student learning of communications skills, (3) clinical consultation guides or styles and (4) optimal curricular structure for communication learning effectiveness. Contexts of communications in the dental chair differ from medical and other allied health professions, given the current mostly dentist-dominant and patient-passive relationships. Patient-centered communication should be trained. Dental students need more practical learning in active listening and patient-centered skills including using role-play, videotaping and ultimately, real patient training. Medical consultation guides are often unwieldy and impractical in many dental contexts, so a shortened guide is proposed. Communication skills need to be learned and taught with the same rigor as other core dental skills over the entire course of the dental curriculum.

Background: Molar incisor hypomineralization (MIH) is the presentation of an enamel defect, where incisors and one (or more) molars are affected. Identifying MIH is significant in restoring its visual defect and avoiding pain or other consequences of this condition. The present cross-sectional study aimed to evaluate the awareness, ability, and confidence in identifying MIH among postgraduate residents in the state of Nevada. Methods: This cross-sectional study was conducted among postdoctoral dental residents at the School of Dental Medicine, University of Nevada, Las Vegas. This cross-sectional study used images of cases of MIH and a survey to collect the data. The survey included demographics, educational background, and basic knowledge of MIH. Results: The response rate to the invitation to participate was 91%. The confidence in identifying MIH was 100%, 50%, and 33.3% for pediatric, orthodontic, and general practice residency (GPR). A total of 70% were aware of this anomaly from their predoctoral dental education and indicated the need for further related education. There was 33% confusion with fluorosis and 16.6% with amelogenesis imperfecta. A total of 66.6% of the participants indicated that they require further education relating to MIH. Conclusion: Within the limitations of the present investigation, MIH awareness among the investigated groups varied but was highest amongst the pediatric residents.

Background: It has been reported that dyslipidemia prevalence and cardiovascular disease risk were increased in subjects with oral lichen planus diagnose. On the other hand, so far, there is no available data on the topic of cardiovascular risk (CVR) in subjects with oral lichen planus (OLP). The main aim of this study, due to lack of any other study covering this topic, was to investigate lipid profile and assess CVR in patients with OLP. Materials and Methods: To create a routine lipid profile, we collected triglyceride serum levels, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol from 63 OLP patients and 63 healthy people representing control subjects. For every patient their individual cardiovascular risk was measured. Results: In comparison with the tested control subjects, patients with OLP had all parameters of the lipid profile elevated, with no differences of statistical importance. Furthermore, the experimental (OLP) and control groups shared similar mean values of the lipid profile parameters. Conclusions: The association of OLP with cardiovascular risk was not established and further studies with more subjects involved are required to validate this connection.

Background: After tooth extraction, the alveolar bone loses volume in height and width over time, meaning that reconstructive procedures may be necessary to perform implant placement. In the maxilla, to increase the bone volume, a mini-invasive surgery, such as a sinus lift using the crestal approach, could be performed. Methods: A crestal approach was used in this study to perform the sinus lift, fracturing the bone and inserting collagen (Condress®). The single dental implant was placed in the healed bone after six months. Results: The newly formed bone was histologically analyzed after healing. Histomorphological analyses confirmed the quality of the new bone formation even without graft biomaterials. This is probably due to the enlargement of the space, meaning more vascularization and stabilization of the coagulum. Conclusion: Using just collagen could be sufficient to induce proper new bone formation in particular clinical situations, with a minimally invasive surgery to perform a sinus lift.

Introduction: The aim of the present study was to compare the quality of the root canal obturation obtained with two different techniques, i.e., thermoplastic gutta-percha introduced through a carrier (GuttaCore) and fluid gutta-percha (GuttaFlow2). Materials and Methods: The study included 40 permanent single-rooted human teeth, divided into two groups and obturated with Guttaflow (group G) and with GuttaCore (group T). The teeth were fixed and transversely sectioned, they were examined by scanning electron microscopy. The dentin–cement–gutta–percha interface and the percentage of voids produced by the two techniques were statistically analyzed. Results: GuttaCore showed a better filling in the apical third of the canal with a percentage of voids equal to 5%. GuttaFlow showed a lower percentage of voids in the middle and coronal thirds of the canal, 1.6% of coronal voids. Statistical analysis showed a statistically significant difference in the percentage of voids in the two groups (GuttaCore and Guttaflow2) in each portion. Conclusions: GuttaFlow2 seems to flow optimally in the middle and coronal third of the canal, with greater difficulty in filling the apical third. Due to the rigidity of the carrier, GuttaCore is able to reach better the most apical portions of the canals, with greater difficulty in creating the three-dimensional seal at the level of the middle third and coronal third.

Conclusions: GuttaFlow2 seems to flow optimally in the middle and coronal third of the canal, with greater difficulty in filling the apical third. Due to the rigidity of the carrier, GuttaCore is able to reach better the most apical portions of the canals, with greater difficulty in creating the three-dimensional seal at the level of the middle third and coronal third.","PeriodicalId":47284,"journal":{"name":"Open Dentistry Journal","volume":"61 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90727360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
