One-year radiographic and clinical performance of bioactive materials in primary molar pulpotomy: A randomized controlled trial.

OBJECTIVES: Mineral Trioxide Aggregate (MTA) is considered the gold standard material for pulpotomy procedures. However, some drawbacks such as poor handling and long setting time are challenging when it is used as pulpotomy dressing in primary molars in children. Hence, the purpose of this study was to compare the radiographic and clinical performance of a premixed, fast setting bioceramic root repair material (BC RRM-F) with MTA in vital pulpotomy procedures of primary molars, with or without the added seal of a stainless steel crown (SSC). METHODS: In this double blinded, four-arm, parallel group randomized contolled trial (RCT), 64 primary molars were randomly allocated to one of the four treatment groups: MTA (PDTM MTA WHITE)+SSC, MTA+GI (bulk fill glass ionomer with glass hybrid technology GC EQUIA Forte® HT), BC RRM-F+GI and BC RRM-F+SCC. All molars were evaluated clinically and radiographically according to the modified Zurn and Seale criteria at 1, 3, 6, and 12 months follow up. Multivariate cox regression models and Kaplan-Meier curves were used for survival analysis. RESULTS: There was no statistically significant difference between the success of both pulp capping materials used. Overall survival analysis showed that using GI instead of SCC as a final restorative material was significantly associated with increased risk of failure. CONCLUSIONS: TotalFill® BC RRM™ Fast Set Putty can be used as an alternative to MTA in primary molar pulpotomy. Regardless of the pulp capping material, one year survival of pulpotomized primary molars restored with SSC is higher compared to those restored with GC EQUIA Forte® HT. CLINICAL SIGNIFICANCE: Clinicians' preference and cost effectiveness may justify the use of either material in primary molar pulpotomy. Parents insisting on tooth-colored restorations for their children's pulpotomized teeth cannot be told that the expectation for success is the same as those restored with SSC, even if calcium silicate-based pulp capping materials are used.

Effect of silver diamine fluoride on the microleakage of flowable resin composite and glass ionomer cement restorations to carious primary dentin: an-in vitro study.

BACKGROUND: This study aimed to evaluate the effect of Silver Diamine Fluoride (SDF) on the microleakage of flowable resin composite (FRC) and resin-modified glass ionomer cement (GIC) restorations bound to carious primary dentin. METHODS: Forty-four extracted carious primary molars were allocated into four groups as follows (n = 11 teeth/group): Group I, Flowable resin composite (FRCa): SDF38% treatment + FRC, Group II, Flowable resin composite (FRCb): FRC without SDF treatment, Group III, Resin-modified glass ionomer cement (GICa): SDF38% treatment + GIC, Group IV, Resin-modified glass ionomer cement (GICb): GIC without SDF treatment. Specimens were subjected to thermo cycling at 500 cycles between 5 to 55 °C (dwell time of 60 seconds) in baths before being immersed for 24 h in a 1% toluidine blue solution. Microleakage testing was conducted for each specimen in two areas; occlusal and gingival. Specimens were evaluated under stereomicroscope at 4x magnification. Results were analyzed using Kruskal-Wallis test followed by pairwise comparisons utilizing Dunn's post hoc test at p ≤ 0.05. RESULTS: Insignificant differences between different groups (p = 0.49) were observed at the gingival walls area readings. The highest value was found in GICb (2.33 ± 0.52), while the lowest value was found in FRCa (1.71 ± 0.76). Insignificant differences between different groups (p = 0.982) were observed at the occlusal walls area readings. The highest value was found in FRCa (1.43 ± 0.98), while the lowest value was found in GICb (1.17 ± 1.33). CONCLUSION: SDF does not adversely affect the microleakage of FRC and GIC restorations bound to carious primary dentin.

"Challenges and concerns faced by parents of a group of Egyptian children with cleft lip/palate: a qualitative study".

BACKGROUND: Cleft lip and palate are the most common developmental anomalies that affect the mouth and related structures. They can both affect children physiologically, socially, and functionally and lead to psychological distress in their parents. The present study aims to understand the challenges parents of cleft lip and palate patients face in Egypt, elucidate how they cope with these challenges, and assess their concerns for the future. METHODS: For the present phenomenological qualitative exploration, the parents of cleft lip and palate patients attending the cleft care clinic were invited to participate in the study through face-to-face recruitment at the clinic. An interview guide about the research question was developed to include standardized open-ended questions providing a framework for structured discussions. The interviews were audio-recorded after obtaining written informed consent from participants then collected data were transcribed for data analysis. RESULTS: Of the 12 participants, there were nine mothers and three fathers. Their children's ages ranged from 1.5 years to 19 years and had different presentations of cleft lip and palate from unilateral cleft lip to complete bilateral cleft lip and palate. Feeding difficulty was one of the main challenges encountered by the parents. At the same time, fear of being subjected to bullying was the main concern for the future of their children. Six themes were noted that were continually reported: Health & Wellbeing; Parental emotions; Parental attitudes & behaviors; Financial aspects; Relationship aspects; and Career/Education. CONCLUSIONS: There were 4 factors that directly impacted the themes, namely: the type of cleft, gender of the child, gender role of the parent, and the age of the child impacted the parental concerns and the challenges faced under the influence of sociocultural beliefs and existing support systems.

Association between periodontal health and trait anxiety in Egyptian women: A cross-sectional study.

OBJECTIVES: This study explored the relationship between periodontal problems and trait anxiety in a sample of Egyptian women. MATERIALS AND METHODS: The Egyptian validated Arabic version of the State-Trait Anxiety Inventory-Trait subscale was used to measure levels of trait anxiety, and the periodontal health status of 451 Egyptian women was assessed using the Community Periodontal Index. Data were also collected on potential covariates such as age, educational level, marital status, parity, smoking, and oral healthcare-seeking behavior. Multivariate logistic regression analysis was done to evaluate the association between periodontal diseases and trait anxiety. RESULTS: Among study participants, and after adjusting for some of the potential confounders, trait anxiety exhibited weak association with periodontal diseases (OR: 1.11; 95% CI= 1.07, 1.14; p <0.001). Also, old age (OR: 1.12; 95% CI = 1.07, 1.17; p < 0.001) as well as parity (OR: 7.26; 95% CI = 2.89, 18.27; p <0.001) were significantly associated with periodontal problems in the adjusted model. CONCLUSION: While the study findings may implicate that personality traits, such as trait anxiety, could be linked to periodontal diseases more research is warranted to confirm or reject this association.

A 1-year Clinical and Radiographic Assessment of Regenerative Endodontic Therapy for Necrotic Primary Molars: A Randomized controlled Trial.

Background: Preservation of necrotic primary teeth is important. Pulpectomy is the gold standard treatment in this situation. Reinfection is the main cause of failure in pulpectomy. The application of regenerative endodontic therapy in mature teeth has the rationale of restoring dental-pulp-like tissue and preventing reinfection. Aims and objectives: The current study was designed to clinically and radiographically assess regenerative endodontics therapy in necrotic primary molars in comparison to zinc oxide eugenol (ZOE) pulpectomy. Materials and methods: A double-blinded randomized controlled trial with three parallel arms and a 1:1:1 allocation ratio was conducted. A total of 54 necrotic primary molars in 39 healthy children aged 4-7 years old were randomly allocated as follows group I-control group, in which ZOE pulpectomy was performed. Group II and III-experimental groups, in which regenerative endodontic therapy (RET) was performed. Modified triple antibiotic paste (mTAP) and Metapex™ were used as intracanal medicaments in groups II and III, respectively. Clinical and radiographic assessments were recorded at baseline, 6 and 12 months. Chi-squared and Fisher's exact tests were used to compare the qualitative data, while Friedman's test was used to study the changes by time within each group. Results: Nonstatistically significant differences were reported between the three groups at the 6 and 12 months follow-ups regarding the clinical or radiographic assessment (p-value = 0.327 and effect size = 0.22), (p-value = 0.055 and effect size = 0.118), respectively. Conclusion: Regenerative endodontic therapy (RET) yielded comparable results to pulpectomy. However, the use of 5 mg/mL mTAP in RET represented the highest level of clinical as well as radiographic insignificant failure. Clinical significance: Regenerative endodontic therapy (RET) provides an acceptable biological alternative to pulpectomy. Trial registration: The protocol was registered at ClinicalTrial.gov with the registration number (NCT04190914). 12/5/2019. How to cite this article: Abdelmoneim DD, Abdelaziz AM, Allam GG, et al.

The impact of oral health literacy on dental anxiety and utilization of oral health services among dental patients: a cross sectional study.

BACKGROUND: Low oral health literacy levels and deficient oral health knowledge jeopardize the communication between dentists and patients in different communities. This study aimed to examine the impact and association of oral health literacy with patients' levels of dental anxiety and their utilization of dental health services. METHODS: This cross-sectional study was conducted at the Misr International University (MIU) dental clinics. The study utilized a structured, interview led questionnaire that was administered by second year dental students, over the period of two successive academic years 2018-2019 and 2019-2020. A total of 440 student interviewed a convenience sample of 440 dental patients: including 269 females (61.1%) and 171 males (38.9%). The questionnaire consisted of four sections; a demographic section, a modified Arabic Rapid Estimate of Adult Literacy (ARELAD-30) Tool that measures the ability of the participants to read 30 commonly used dental terms. This questionnaire was modified by the authors to measure the participants' knowledge by asking them to choose the most accurate meaning for each word based on their previous knowledge. Scoring was dependent on the participant's immediate correct pronunciation, as well as comprehension of each word. The Arabic Modified Dental Anxiety Scale (AMDAS) was used to measure the level of dental anxiety, and the dental health service utilization was measured using the Utilization of oral health services questionnaire. RESULTS: One quarter (24.1%) of the participants read the 30 items of the A-REALD correctly. The average percentage of correct responses to the meaning of the dental terms was 71.2%. There was no statistically significant association between A-REALD and knowledge scores (Spearman's Correlation coefficient ρ = -0.008, p-value = 0.872). There was a statistically significant inverse correlation between age and MDAS (Correlation coefficient ρ = -0.146, p-value = 0.002). A-REALD scores were inversely correlated with time since last visit (Regression coefficient = -0.027, p-value = 0.036, with 95% CI: -0.052 - -0.002). CONCLUSION: Within the limitations of this study, it can be concluded that oral health literacy is significantly associated to dental health services utilization, while, dental anxiety is related to other variables, such as age and gender.

"Knowledge, clinical experience, and perceived need for training regarding molar-incisor hypomineralization among a group of Egyptian dental students: a cross-sectional study".

BACKGROUND: Molar-Incisor Hypomineralization (MIH) is a common oral health condition that can lead to difficulties and complications for both dental professionals and patients. It also has a negative impact on the oral health-related quality of life. The present study aimed to assess the knowledge, clinical experience, and perceived need for training of a group of Egyptian dental students regarding MIH. METHODS: Paper-based survey administration method was used to collect the responses of dental students regarding their knowledge, clinical experience, and perceived need for training about MIH. The survey consisted of two sections of questions regarding clinical features, etiological factors, prevalence, materials used in treating these teeth, factors affecting the choice of restorative materials, and their preferences regarding clinical training of MIH. Descriptive statistics was used for the data analysis by using SPSS® Statistics Version 26. RESULTS: About two-thirds of the respondents were familiar with MIH (69.2%). The vast majority of students (87.8%) had difficulty distinguishing MIH as a developmental defect that differs from other tooth conditions (p < 0.001); most commonly enamel hypoplasia. The most common defects seen by the respondents were yellow/brown opacities (59.1%). Nearly half of the students (45.2%) choose composite resin as the material of choice for the treatment of MIH-affected teeth with aesthetics being the most common factor affecting the selection of restorative material. Almost all students expressed their needs for further clinical training on MIH, especially on treatment aspects. CONCLUSIONS: Most students are familiar with MIH theoretically. However, there is an urgent need to include clinical training on MIH diagnosis in the practical sessions of pediatric dentistry courses.

COVID-19 vaccine acceptance and perceptions among dental teaching staff of a governmental university in Egypt.

BACKGROUND: Vaccine acceptance among healthcare workers (HCWs) is an important determinant of its acceptance among the general population. Dentists are an essential group of HCWs who are at an increased risk of COVID-19 infection. This study aimed to assess vaccine acceptance and its determinants among a group of dental teaching staff in Egypt. METHODS: An Internet-based cross-sectional study was conducted where the dental teaching staff of a governmental university in Egypt were targeted using total population sampling. Data was collected on socio-demographics, attitudes towards COVID-19, risk perception, general attitudes towards vaccination, vaccine acceptance, and concerns about COVID-19 vaccines, along with barriers and motivators to vaccination. Multivariate regression was done to determine factors significantly associated with unwillingness to receive COVID-19 vaccine. RESULTS: A total of 171 dental faculty members participated in the study. At the time of data collection (August 2021-October 2021), 45.6% of the dental teaching staff were willing to receive the vaccine, while 46.7% were against vaccination, and 7.6% were vaccine hesitant. Female gender, not having a private practice, not intending to travel internationally, having anyone sick in the immediate social circle, and being more anxious about COVID-19 were significantly associated with unwillingness to receive the COVID-19 vaccine. CONCLUSION: At the time of conducting this study (August 2021-October 2021), less than half of the participating dental teaching staff in the studied Egyptian university were willing to receive the COVID-19 vaccine. Findings of the current study can guide Egyptian health authorities to adopt strategies that correct misconceptions among HCWs, educate them and build their trust in the efficacy and safety of COVID-19 vaccines, which can ultimately increase its acceptance in the general population.

Applying the Kirkpatrick model to evaluate dental students' experience of learning about antibiotics use and resistance.

INTRODUCTION: "Antibiotic resistance" is of main concern in global health and that it could hinder the achievement of sustainable development goals. One of the reported contributing factors is the irrational prescribing behaviour of healthcare professionals including dentists. Efforts to design and evaluate effective educational programmes for undergraduate dental students about appropriate prescribing behaviour during their early educational years could mitigate the risk of antibiotic resistance. MATERIALS AND METHODS: A total of 322 students participated in the study. Their knowledge of antibiotics and antibiotic resistance was assessed. Students received a specially designed, interactive educational programme. The success of the programme was assessed after the educational sessions and 2 years later using Kirkpatrick's four-level evaluation model. RESULTS: This study is the first study to use Kirkpatrick model to evaluate an educational programme for dental students. The results of the first level of evaluation showed an overall satisfaction score of 82.1%. The second level revealed an increase in the percentage of correct answers after the educational sessions from 68.3% to 80%, and significant agreement with responsible antibiotics usage (p-value = .020, Effect size = 0.121). The third level showed that the percentage of correct answers 2 years later was 87.5%. The fourth level confirmed the success of the programme as 88.9% of participants reported using the knowledge gained from the programme when prescribing antibiotics. CONCLUSIONS: Our study emphasises the success of the used educational programme and highlights the need for educational interventions in the under graduate dental curriculum.

Periodontal diseases and potential risk factors in Egyptian adult population-Results from a national cross-sectional study.

BACKGROUND: Despite the interdependence of general and periodontal health, there is paucity of national representative data on the prevalence of periodontal diseases and their associated risk factors in Egyptian population. This cross-sectional study, thus, aimed to assess the prevalence of periodontitis and tooth loss among Egyptian adults and investigate the association between potential risk factors and periodontal diseases. METHODS: A total of 5,954 adults aged ≥ 20 years were included in this study as a subsample from Egypt's national oral health survey. Periodontitis was diagnosed with Community Periodontal Index 'CPI' scores ≥3 and tooth loss not due to caries was included in the analysis. Socio-demographic data and information on behavioral factors and history of diabetes were gathered in a face-to-face interview. Logistic regression was done to interpret the impact of potential predictors on the incidence of the two selected outcome variables. RESULTS: The overall prevalence of periodontitis was 26% and regression analysis revealed that higher odds of periodontitis existed among illiterate participants (OR = 1.74; 95% CI: 1.40-2.17), smokers (OR = 1.93; 95% CI: 1.69-2.20) and rural residents (OR = 1.16; 95% CI: 1.03-1.30). On the other hand, old age, frequency of dental attendance and history of diabetes were the main predictive factors for tooth loss. CONCLUSIONS: Among Egyptian adults, periodontal diseases were strongly associated with a multitude of modifiable and non-modifiable risk factors and inequalities in distribution of periodontal treatment needs were determined mainly by age, gender, level of education and residency location.

Laboratory evaluation of the potential masking of color changes produced by silver diamine fluoride in primary molars.

BACKGROUND: The importance of Silver diamine fluoride (SDF) as a minimally invasive and nonaerosolizing management during COVID-19 pandemic has highly increased. SDF is a caries-arresting agent that causes staining of tooth structure. Managing this discoloration will increase its acceptance in treating primary teeth. The main aim of this study was to quantify the color change associated with the application of SDF on extracted carious primary molars, the potential masking of this color change by potassium iodide (KI), composite (CMP) and glass ionomer cement (GI) and the effect of aging on this color masking effect. METHODS: An in-vitro study in which 52 carious primary molars were collected, prepared, and distributed randomly into four groups equally as follows: Group A: SDF 38%; Group B: SDF 38% + KI; Group C: SDF 38% + CMP; Group D: SDF 38% + GI. Color changes were recorded for each sample at baseline, and after application of the tested materials. Moreover, all samples had undergone Suntest aging followed by a third color reading. CIELAB values L*, a*, b*, ΔL, Δa, and Δb were measured, ΔE was calculated, and data were analyzed using multivariate analysis of variance (MANOVA) and post-Hoc Scheffé test (p < 0.05). RESULTS: MANOVA revealed the significant influence of the factor 'material'. SDF caused an obvious color change compared to the color of carious dentin. Regarding ΔL, the color change of groups C and D was not significant directly after application of the tested materials. After aging, it was significant among all groups, including groups C and D. In Δa there was a difference between SDF and groups B and C after application of the tested materials, and aging produced the same results. The color shifts of Δb of all tested groups varied significantly from one another. After aging, there was no difference between group D and either group A or B. CONCLUSIONS: Treatment with SDF caused obvious discoloration of carious dentin. Directly after SDF application, all tested materials could effectively mask the color change associated with the application of SDF. CMP was the only material whose color masking effect was not completely reversed by aging.

Assessing Knowledge, Practices, Use and Raising Awareness of Antibiotic And Antibiotic Resistance Among Dental Patients Before and After Educational Sessions / Avaliação de conhecimentos, práticas, uso e conscientização sobre antibióticos e resistência a antibióticos entre pacientes odontológicos antes e depois das sessões educacionais

Objectives: Education and awareness-raising are global health policy tools to modify public behavior towards antibiotic resistance. Considering the high frequency of antibiotic use and self-medication in Egypt, together with the lack of an awareness agenda, our objectives were to assess the knowledge and practices related to antibiotic use and resistance among patients attending dental clinics, and to evaluate the changes in knowledge following a specially designed one-on-one educational session. Material and Methods: A convenience sample of 310 dental patients participated in this study. A modified questionnaire was used to assess knowledge and practices related to antibiotic use and resistance. Second-year dental students were trained to administer the questionnaire and to use the educational materials they designed to raise awareness. Following the education session, patients completed another similar questionnaire to assess the changes in their knowledge. Results: Increasing awareness of antibiotic resistance can be an effective way to address the antibiotic resistance crisis. More than half of the participants (55.6%) did not know whether antibiotics treat diseases caused by bacterial or viral infections. The majority of participants (85.5%) had taken antibiotics during the last year, and (50.5%) of them had taken the same antibiotic more than once. Higher educational levels of the participants were significantly associated with a higher level of knowledge. Statistically significant increase in the percentages of correct answers to all questions were observed after the educational sessions. Conclusion: The one-on-one educational session is an effective approach to address the antibiotic resistance crisis (AU)

Objetivos: Educação e conscientização são ferramentas de política de saúde global para modificar o comportamento do público em relação à resistência aos antibióticos. Considerando a alta frequência de uso de antibióticos e automedicação no Egito, juntamente com a falta de uma agenda de conscientização, nossos objetivos foram avaliar o conhecimento e as práticas relacionadas ao uso de antibióticos e resistência entre pacientes atendidos em clínicas odontológicas, e avaliar as mudanças em conhecimento após uma sessão educacional especialmente projetada para este assunto. Material e Métodos: Uma amostra de 310 pacientes odontológicos participou deste estudo. Um questionário modificado foi usado para avaliar o conhecimento e as práticas relacionadas ao uso e resistência a antibióticos. Os alunos do segundo ano do curso de odontologia foram treinados para aplicar o questionário e usar os materiais educacionais que elaboraram para aumentar a conscientização. Após a sessão educacional, os pacientes responderam a outro questionário semelhante para avaliar as mudanças em seus conhecimentos. Resultados: Aumentar a conscientização sobre a resistência aos antibióticos pode ser uma forma eficaz de lidar com a crise de resistência aos antibióticos. Mais da metade dos participantes (55,6%) não sabia se os antibióticos tratam doenças causadas por infecções bacterianas ou virais. A maioria dos participantes (85,5%) havia tomado antibiótico no último ano e (50,5%) deles havia tomado o mesmo antibiótico mais de uma vez. O maior nível de escolaridade dos participantes foi significativamente associado a um maior nível de conhecimento. Aumentos estatisticamente significativos nas porcentagens de respostas corretas para todas as questões foram observados após a sessão educacional. Conclusão: A sessão educacional individual é uma abordagem eficaz para lidar com a crise de resistência aos antibióticos. (AU)

Effect of the addition of chlorhexidine and miswak extract on the clinical performance and antibacterial properties of conventional glass ionomer: an in vivo study.

BACKGROUND: Antibacterial restorations can increase the success rate of minimum invasive dentistry especially in young permanent molars with deep carious lesions as an attempt to preserve maximum dental structure and avoid pulp exposure. Further research is warranted to evaluate different antibacterial agents. OBJECTIVES: This study aimed to evaluate the efficacy of adding chlorhexidine gluconate (CHX) or aqueous miswak (Salvadora persica) extract on the clinical performance and in vivo antibacterial activity of conventional anhydrous glass ionomer cement (GIC). DESIGN: The study was a randomized clinical trial. Sixty young permanent molars, with deep carious lesions in 6- to 9-year-old children were included. After randomization, atraumatic restorative treatment (ART) or stepwise excavation was performed followed by bacterial sampling from the center of the remaining carious dentine in the floor of the pulp. GIC powder was mixed with 0.5% chlorhexidine gluconate liquid in group I; with 100% aqueous miswak in group II; and with deionized water in group III (control). Clinical performance for all groups was assessed at 3, 6, and 9 months. After 9 months, restorations were removed and a second bacterial sample was collected for Streptococcus mutans (S. mutans) quantification and analysis by real-time polymerase chain reaction (PCR) test. RESULTS: Results showed no statistically significant difference in the success rate of the three groups at the 3-month interval. At 6 and 9 months, however, restoration success was 75% then 60% in group I, 100% then 90% in group II, and 95% then 85% in control group. Group II and the control group showed statistically significant higher survival rates than group I. All groups showed reduction in S. mutans counts in underlying dentine, but the percent reduction was significantly higher in group I. (P < 0.001). CONCLUSIONS: The addition of CHX and miswak to GIC showed superior antibacterial properties than conventional GIC, without seriously affecting the clinical performance of the restoration until the 6-month follow-up, but failure significantly increased in terms of marginal defects at 9 months with CHX (group 1).
