Objective: To evaluate effect of material thickness and translucency of two different hybrid CAD/CAM materials on their masking ability.

Materials and methods: 40 rectangular-shaped specimens (12 × 14 mm) were obtained from Vita Enamic and Grandio blocks at 0.5 and 1 mm-thick (n = 10/group). Colour parameters of specimens were measured on PMMA tooth-coloured replica backgrounds (A2, C4) and black, white backings using dental spectrophotometer. Translucency parameter (TP) and masking ability (∆E₀₀) values of tested materials with 0.5, and 1 mm thicknesses were calculated. Quantitative variables were compared between groups using student t-test.

Results: TP and ∆E₀₀ significantly decreased as thickness of tested materials increased. Grandio showed significantly higher TP values. There were significantly lower ΔE₀₀ values for Vita Enamic compared to Grandio at 1 mm thickness and inversely insignificant at 0.5 mm. The 0.5 mm-thick ∆E₀₀ of tested materials was above clinical acceptability threshold, whereas, 1 mm-thick did not exceed showing better masking properties.

Conclusions: Thickness is more effective for colour masking than translucency. In thin thickness, the masking ability is less effective, irrespective of tested materials. Translucency of tested materials was affected by their composition. Both hybrid CAD/CAM materials are promising alternatives for masking dark discolouration at 1 mm-thick.

Background: Patient adherence is a key factor in achieving orthodontic success. While in recent years there have been changes in orthodontic healthcare, no recent comprehensive reviews regarding adherence in orthodontics are available. Therefore, the aim of this planned scoping review is to systematically map the available literature regarding patient adherence in orthodontics to identify factors associated with patient adherence and to investigate if there are knowledge gaps in the available literature.

Methods/design: This protocol was drafted according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analysis Protocols (PRISMA-P) statement and the PRISMA extension for Scoping Reviews (PRISMA-ScR). For the methods Arksey and O'Malley's framework and the Reviewer's Manual of the Joanna Briggs Institute for conducting scoping reviews were consulted. The inclusion criteria for this scoping review are studies of all designs assessing any form of adherence in orthodontics, published in English from 2006 onwards. The exclusion criteria are studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those solely treated for obstructive sleep apnoea. Case reports and studies published in non peer reviewed journals will also be excluded. The following electronic databases will be searched: Embase, PubMed, and Web of Science Core Collection. The following key terms will be used in the search strategies: 'treatment adherence and compliance', and 'orthodontics'. Multiple reviewers will independently screen the results and perform the data charting process. A narrative description will be provided for the analysis of the included studies. The results will be categorized into multiple topics based on recommendations by previous studies into patient adherence. Identified knowledge gaps will be reported and recommendations for future research will be suggested.

Discussion: No systematic review has previously assessed this exact topic. Because of the broad-spectrum research questions and the expected widely scattered literature a scoping review approach was chosen over a systematic review approach. The Academic Centre for Dentistry Amsterdam (ACTA) has been conducting research in patient adherence in orthodontics up to 2006 and therefore only studies published from 2006 onwards will be researched in this review. Identifying knowledge gaps and summarizing and disseminating research findings on this topic is important for every dental professional performing orthodontic treatment.

Objective

A comparison between commercial computer screens and DICOM-calibrated medical screens for characterizing anatomy and diagnosing dental pathologies was performed. The aim of this study was to evaluate and compare the ability of each of those screens to identify root apices and widening of the periodontal ligament (PDL) in the posterior maxillary area.

Materials and Methods

Digital X-ray images of 53 maxillary molar teeth were examined by means of a commercial computer screen and again two months later with a DICOM screen to compare their ability to help identify and diagnose PDL widening and to locate the root apices of those teeth.

Results

The DICOM screen had a significantly better ability to identify widened PDLs (from 31.4% to 34.8% of the cases compared to 19% to 26.1% for the commercial screens, P < .001), depending upon the observer. The DICOM screen was also significantly superior in depicting the root apices compared to the commercial screens (from 77.4% to 83.6% of the cases compared to 56% to 66.7% for the commercial screens, P < 0.001), depending upon the observer.

Conclusion

DICOM-calibrated medical screens were significantly superior to commercial computer screens for identifying widened PDLs and locating the root apex in the posterior maxillary area.

Objective: To investigate the significant impact of oral health on the quality of life of older individuals in Riyadh, Saudi Arabia, across various socioeconomic and demographic contexts.

Methods: A cross- sectional study was conducted, involving the distribution of a translated online questionnaire based on the OHQoL-UK® tool to evaluate oral health-related quality of life OHRQoL. This included utilizing the Oral Health Quality of Life Scale to assess overall quality of life.

Results: A total of 586 participants were involved in the study, with the majority being over 60 years old (77.1%). The mean score of OHRQoL was 3.79. The Social Dental Scale SDS had a mean score of 0.71. The General Oral Health Assessment GOHS scored 3.51 on average. The mean score of Dental Impact Profile DIP was 3.12. The Subjective Oral Health Status Indicators SOHSIs had a mean score of 3.82. The mean score of Oral Health Benefit of Life Inventory OHBLI averaged at 4.04, and Dental Impact on Daily Living DIDL scored an average of 4.05. The mean scores of OHRQoL and Oral Impacts on Daily Performance OIDP were 3.90 and 3.89 respectively. Cronbach's Alpha values ranged from 0.854 to 0.939, with an overall questionnaire reliability of 0.977, indicating a good reliability of the study's tool.

Conclusion: Older adults exhibited lower OHRQoL compared to younger adults, particularly influenced by factors such as health insurance coverage, monthly income, and educational level. It is essential to develop health programs specifically tailored for senior adults to safeguard their overall health and quality of life. Making health and medical insurance obligatory and accessible to all individuals is crucial for enhancing their QoL and reducing the diseases.

Background: Patient adherence is a key factor in achieving orthodontic treatment success. Despite an evolution in orthodontic healthcare, no recent comprehensive reviews are available on patient adherence in orthodontics. This scoping review provides an evidence-based overview of the literature available on multiple aspects of patient adherence in orthodontics, during both active treatment as well as during the retention phase. Knowledge gaps identified in the literature are listed.

Methods: The protocol for this scoping review was registered in the Open Science Framework ( https://doi.org/10.17605/OSF.IO/EC6QD ). Electronic databases and reference lists of relevant studies were searched up to 9 February 2023. The inclusion criteria were studies investigating any form of patient adherence in orthodontics published in English from 2006 onwards. The exclusion criteria were studies investigating adherence in the following patients: those with an intellectual or physical disability that could affect their ability to coincide with their therapist's recommendations and advice, those with oral cleft and craniofacial conditions, and those treated solely for obstructive sleep apnoea. Non-peer-reviewed studies and case reports were also excluded.

Results: A total of 3284 articles were identified, 60 of which met the criteria for final inclusion.

Conclusions: There is no conclusive evidence on which factors have a significant impact on patient adherence and how patient adherence can be promoted. The degree of patient adherence is generally not compared to achieved treatment results or stability of treatment results, making it difficult to provide clear statements about the impact of the degree of adherence on desired treatment results or orthodontic stability.

Background: Ensuring optimal oral hygiene is crucial for preserving the well-being of hard and soft tissues within the oral system. A lack of proper oral hygiene can have a detrimental impact on an individual's health, leading to conditions such as caries and periodontitis. Therefore, this study investigated the association between the knowledge and practices of older patients in oral hygiene in Addis Ababa, Ethiopia.

Methods: A facility-based cross-sectional study was carried out on 111 older patients who presented at purposively selected dental clinics in Addis Ababa. A convenience sampling method was used to recruit study participants. The data were collected using a pretested structured questionnaire. The questionnaire included information related to the patient's knowledge and practices related to oral hygiene. The data were analyzed using SPSS version 23. Descriptive statistics were used to analyze the data. Multivariate logistic regression was performed to investigate the associations between independent and dependent variables. Adjusted odds ratios with 95% confidence intervals (95% CIs) were estimated, and variables with a p value < 0.05 in the multivariate analysis were considered significant.

Results: The median age of the study participants was 70.31 years (65-100). Inadequate oral hygiene knowledge was found in 53.15% of the participants, while more than three-quarters (83.78%) of the older participants practiced poor oral hygiene. Older patients with good oral hygiene knowledge were 7.6 times more likely to practice good oral hygiene practices (AOR, 7.6; 95% CI (2.05-27.9)).

Conclusions: Poor oral health is significantly associated with various health problems, particularly in older people. This study examined the relationship between oral health knowledge and practices in older dental patients and revealed insufficient knowledge and practices among participants. The results showed a notable link between oral health knowledge and practices in this demographic group, highlighting the need for support to improve oral health status. Organizations should increase awareness among older patients to improve their oral health status.

Aim: This study aimed to evaluate the oral health status of children with hearing impairments and assess the relationship between various oral health factors and the Pediatric Oral Health-Related Quality of Life.

Materials and methods: This observational cohort study involved 90 hearing-impaired children aged 6-12 years. Diagnostic tools such as pure-tone audiometry were used to evaluate their hearing abilities. Dental health was assessed by calculating DMFT, dmft, Plaque and Gingival indices. The oral health-related quality of life was measured using the POHRQoL.

Results: The severity of hearing impairment varied with 3% having severe hearing loss, 13% having profound hearing loss, and 83% having complete hearing loss. A high prevalence of dental cavities with 93% of children affected was found. DMFT score was similar between males and females (2.5 ± 0.3 vs. 2.3 ± 0.3 respectively). Males exhibited a higher mean dmft score (4.1 ± 0.5 vs. 3.3 ± 0.5), and a higher mean Plaque Index (1.9 ± 0.1 vs. 1.5 ± 0.1). On the other hand, females showed a higher mean Gingival Index (0.9 ± 0.1 vs. 1.1 ± 0.2). Results indicated a decreased OHRQoL with a mean POQL score of 6.4 ± 2.89. Spearman's test revealed a significant positive correlation between POQL total score and DMFT scores (P = 0.000), dmft scores (P = 0.000), Plaque Index scores (P = 0.000), and Gingival Index scores (P = 0.038). There was a weak positive correlation between hearing impairment severity and POQL total score, it was not statistically significant.

Conclusions: Children who have hearing impairments exhibit poor oral health, and levels of dental caries, which can negatively impact their overall POHRQoL. Therefore, it is highly recommended to start specialized oral health education and comprehensive dental care programs to improve their OHRQoL.

Objective: To evaluate educational impact of game-based learning (GBL) in orthodontic education.

Methods: A systematic search was undertaken across four databases (Scopus, PubMed, ProQuest Dissertations & Theses Global, and Google Scholar) to identify relevant articles published from January 2000 to December 2023. Additionally, the reference lists of identified literature were examined to further search for relevant literature. The last search was performed on 28 January 2024.

Results: Following the article selection process, seven articles were included in this systematic review, comprising four randomized control trials and three questionnaire surveys. Six articles were assessed to have a moderate risk of biases, whereas one research exhibited a low risk of bias. GBL interventions assessed in five articles were designed in digital format, while one study implemented evaluated traditional learning, and another employed a card game format. Two RCTs indicated a greater effectiveness of GBL in enhancing learner performance compared to traditional learning methods, while one article found no significant difference. Across all articles, positive perceptions of GBL were consistently highlighted at both undergraduate and postgraduate levels.

Conclusion: This systematic review supports the potential of GBL in orthodontic education. The implementation of GBL is recommended to integrate entertaining and educational elements, fostering learner performance within engaging learning environments. However, it is imperative to acknowledge that the overall quality of evidence is limited, primarily due to the moderate risk of biases identified in six of the included articles. Consequently, further high-quality experimental studies are required to validate the effectiveness of GBL in orthodontic education.

Introduction: Decades of evidence have demonstrated a lack of workforce diversity and sustaining disparities in academic dentistry and professional practice. Underrepresented minority students may face challenges and implicit bias during the dental schools' admission/selection process. This review collected papers from different countries to summarize the Equity-Diversity-Inclusion (EDI)-related strategies that dental schools worldwide have used in their admissions process to increase diversity.

Methods: A comprehensive search using MEDLINE (via PubMed), ERIC, Cochrane Reviews, Cochrane Trials, American Psychological Association Psyc Info (EBSCO) and Scopus was done between January and March-2023. All types of articles-designs were included, except comments and editorials, and all articles selected were in English. Two independent investigators screened the articles. Extracted data were general characteristics, study objectives, and EDI-related strategies.

Results: Sixteen publications were used to construct this manuscript. The year with the greatest number of publications was 2022. Type of studies were case studies/critical reviews (50%), cross-sectional (including survey and secondary data analysis) (n = 5, 31.25%), qualitative methods of analysis (n = 2, 12.5%), and retrospective/secondary data collection (n = 1, 6.25%). The strategies described in the articles were related to (1) considering the intersectionality of diversity, (2) using noncognitive indicators during the school admissions process to construct a holistic selection process, (3) diversifying, professionalizing, and providing training to admissions persons who had leadership roles with the support from the dental school and the university, and (4) allocating financial investments and analyzing current policies and procedures regarding EDI.

Conclusions: This review aggregated interesting findings, such as: some schools are considering the intersectionality of diversity as a way to include underrepresented minorities and to diversify the students-body. The recent growth in publications on EDI during dental admission/selection process might indicate a positive movement in this field.
