Introduction: Communication is a central part of our daily clinical lives and forms the foundation of a good professional relationship. This study aims to evaluate the attitudes of residents at the Faculty of dental medicine (FDM) UNIVERSITY HASSAN II CASABLANCA regarding the learning of communication skills. Methods: This is a cross-sectional study to assess the attitudes of FDM residents about learning communication skills, we distributed the questionnaire to all residents. We used as an instrument an anonymous questionnaire in English, this questionnaire is divided into two parts: part A devoted to socio-demographic data such as age, gender, and year of study, and part B used a validated scale developed by Rees to measure residents' attitude towards social sciences. Results: all residents agreed to complete the questionnaire, responses, i.e. a response rate of 100%, the mean age of the residents was 26,9 ± 2,96, with extremes ranging from 23 to 40 years. The score of positive attitude score over the entire study population was 53.13 ± 5.2 (43-63) and the mean score of negative attitude score was 36.77 ± 7.01 (24-52). The residents have manifested an interest to participate in CS courses. Discussion: The success of the therapeutic relationship cannot be achieved without a certain congruence between the patient and the practitioner. In addition, it appears that the only way to achieve this goal is through communication. Communication is very important for a successful therapeutic relationship in dentistry, several studies have focused on the communication training of dental students, and these studies have recommended from their findings that it is necessary to include communication skills courses and examinations in the dental curriculum. Conclusion: It is concluded from our study that dental residents are interested in learning communication skills. It is therefore proposed to continuously train residents in communication skills as part of their training curriculum and to evaluate the learned communication skills continuously by professors.

Aims: The aim of this study was to use Bjork-Jarabak analysis to evaluate and compare cranial base linear and angular measurements in Sudanese patients with skeletal Class I, II, and III relationships, and compare the results with previous reports from Jordan and other regions. Material and Method: A total of 103 pretreatment lateral cephalograms of Sudanese patients aged 18-22 years were analyzed. Results: showed that Sudanese males had significantly higher mean values for the Gonial angle and mandibular body length, while Sudanese females had significantly higher mean values for the Articulare angle. In Class I, Jordanians had significantly higher mean values for the Gonial angle and Bjork sum of angles compared to Sudanese. In Class II, only the saddle and articular angles showed significant differences. In Class III, Jordanians had significantly higher mean values for the Articulare angle, Gonial angle, Bjork sum of angles, and body of mandibular length compared to Sudanese. Additionally, Jordanian males exhibited significantly higher mean values for the Saddle angle, Bjork sum, and posterior cranial base compared to Sudanese males. However, Sudanese females exhibited an extremely statistically significant difference in ramal height, while Jordanian females showed significantly higher mean values for the Gonial angle and Bjork sum of angles compared to Sudanese females. Conclusion: These findings are important for orthodontists to make accurate diagnosis and treatment decisions for patients, considering both appearance and function.

Aims: The purpose of this study was to investigate the correlation between dental, skeletal, and soft tissue variables and compare the results with Saudi study and other previous studies. Material and Method: The sample size consisted of 29 adult Sudanese patients (ages 18 to 25) seeking orthodontic treatment, and 19 variables were examined. The error of the method was assessed using Student's t-test, and canonical correlation analysis was used to analyze the correlation between soft and hard tissues. Results: The study found that the Sudanese population had higher mean values in dental and soft tissue variables compared to the Saudi population, while similar mean values were found in the skeletal sagittal relationship, except for the vertical relationship, where the Saudi population had a higher tendency for an open basal configuration. The canonical analysis revealed that the upper and lower incisors' inclinations had a strong negative loading, while the nasolabial angle and lower lip thickness and position had moderate loading. Conclusion: These findings show the impact of these variables which can help the clinician in diagnosis, prediction and assessment of post treatment changes. Additionally, the multivariate statistical analysis extracted a clinically significant association between soft tissue and hard tissue.

This study identified the specific factors which influence the treatment of gum disease. Specifically, the aims are to examine i) the differences in the prevalence of self-reported periodontitis treatment in 2011–2012 and 2017–2018, ii) the association between the background characteristics of respondents and treatment of gum disease, iii) the effects of the background characteristics on the treatment of gum disease and iv) reasons for the lack of access to dental care in 2011–2012 and 2017–2018. Data from the National Health an Nutrition Examination Survery (NHANES) oral health questionnaires 2011-2012 and 2017-2018 were used. NHANES is a periodic survey conducted by the National Center for Health Statistics of the Centers for Disease Control and Prevention. This data represents a stratified, multistage probability sample of the civilian noninstitutionalized population in the 50 United States U.S) and the District of Columbia. Binary multivariable logistic regression was used to examine the socioeconomic predictors of self-reported therapy for gum disease. Compared to 2011-2012, more participants accessed oral health care services during 2017-2018, resulting in fewer people seeking treatment for gum disease. Affordability and lack of dental health insurance were the primary reasons for not receiving treatment for gum disease. Compared with Whites, Asians were more likely to report having had treatment, followed by Hispanics and Blacks. Increasing oral health services for the elderly could improve access to care related to periodontal disease in this cohort of patients. In addition, the expansion of dental coverage with reduced out-of-pocket expenditure could improve access to dental services and overall health.

Summary: The wide variety of disorders and abnormalities affecting the manducatory apparatus has led to a multitude of therapies of various kinds including orthopedic, kinesiological as well as pharmacological treatments. Several studies have highlighted the effectiveness of orthopedic therapies using occlusal splints as well as kinesiological treatments. However, pharmacological treatments, by their multitude and their diversity remain little documented regarding clinical efficiency, with the absence of a global conclusive study. The aim of this work is to conduct a systematic review evaluating the clinical efficacy of the drugs used in the treatment of temporomandibular dysfunction. Materials and Methods: This is a systematic review questioning the Pubmed database. The research was conducted using the following key words: "Craniomandibular disorders"; "Drug therapy"; "Relaxing Muscle, Central". Articles published between January 2012 and end of August 2017 and meeting the eligibility criteria were identified after reading their titles then summarized by 2 readers. The critical analysis of the methodology was conducted based on the PICO criteria and the JADAD scoring analysis (strengths and weaknesses of each study). The effectiveness of drugs was evaluated based on their action on the following three parameters: Dyskinesia, pain and noise. Results: Of the 420 references originally found on Pubmed, 23 articles were selected. After full reading of the 24 articles selected and application of the JADAD score: • 3 articles treated botulinum toxin including 1 high rank and 2 low ranks for a conclusion in favor of the toxin. • 7 articles discussed hyaluronic acid, 5 of which ranked high and 2 of low rank all agreeing on the efficacy of this therapy. 5 articles on corticosteroids, including 1 high and 4 low, however, no consensus has been reached on its effectiveness. Only 1 item of high rank proved the beneficial effect of anesthetics on muscle pain. 1 high-ranked study and 1 low-ranked trial for nonsteroidal anti- inflammatory drugs that have not been conclusive about its effectiveness. • 3 low-grade items treating PRP were able to demonstrate efficacy as an adjunct to arthrocentesis. 1 low ranking article on painkillers has proven its value as an adjunct to arthrocentesis.

Background: Osteoporosis is a metabolic bone disease, which impairs and/or delays the regenerative response of calcified tissues. Aim: The aim of this study was to assess the histopathologic response to direct pulp capping in osteoporotic rats that received a preoperative treatment with Zoledronic acid, a bisphosphonate which is currently prescribed for treating osteoporosis. Methodology: Two groups, each with 7 osteoporotic female Wistar rats (n=7) received either an intravenous dose of 100 mg/kg of Zoledronic Acid (Group 1) or the same volume of sterile saline (Group 2). One week later, the pulps of the right and left mandibular first molars of each animal were exposed and capped with Biodentine. After 20 days the animals in Group 1 received a second similar dose of Zoledronic acid and Group 2 a similar second dose of sterile saline. After 38 days the animals were euthanized and a total of 28 teeth (14 per group) were prepared for histologic analysis evaluating the following parameters: inflammation, reparative hard tissue formation, odontoblast cell layer organization, fibrous tissue, and necrosis. Results: In Group 1 the reparative hard tissue formation was scarce with preservation of the pulp tissue structure and the odontoblast cell layer. In Group 2 the pulp was preserved as a fibrous reticular-like structure. Reparative hard tissue formation was totally absent and the odontoblast cell layer was atrophic or absent. In both groups, no inflammation or necrosis was observed. Conclusions: The intravenous administration of Bisphosphonate (Zoledronic Acid) did not promote pulp healing in osteoporotic rats.

Aim: This study aimed to compare the fracture resistance exhibited by roots on instrumentation using two endodontic rotary systems: SANI S3 and EdgeEndo X7 rotary file systems. Materials and Methods: Sixty recently extracted human mandibular premolars comprising single root canals were selected in this study. All specimens were decoronated and mounted perpendicularly in self-cure acrylic resin blocks exposing 6 mm of the roots out of the acrylic resin blocks. The specimens were divided into two experimental groups, according to NiTi rotary systems used and one control group (n = 20). After instrumentation, the specimens of both experimental groups were then filled using master Gutta-percha cones size 35 (0.04 taper) and obturation was done using continuous wave compaction technique. The specimens were kept at 37 °C and 100% humidity for 2 weeks to allow complete setting of the sealer. Root fracture resistance was assessed using a universal testing machine (Instron) and the amount of load necessary for root fracture was recorded in Newtons (N). Statistics: Data were collected, tabulated and statistically analyzed using one-way ANOVA test and Tukey’s posthoc test. Results: Group C (control) exhibited the highest mean fracture force (357.13 ± 20.61) while group A (SANI S3) showed the lowest mean fracture force (192.60 ± 22.73). One-way ANOVA test showed statistically significant differences between tested groups. Regarding inter-group comparisons using Tukey’s test, there was a significant statistical difference between groups (A and B) and between groups (A and C). Furthermore, there was a statistically significant difference between groups (B and C). (P?0.05) Conclusion: 1-Root canal instrumentation with NiTi rotary files possessed a negative impact on roots and higher risks of root fractures compared to intact unprepared roots. 2-Design of NiTi files with improved cutting efficiency could diminish the risk of crack formation in root canal dentinal walls.

Materials and Methods: Sixty recently extracted human mandibular premolars comprising single root canals were selected in this study. All specimens were decoronated and mounted perpendicularly in self-cure acrylic resin blocks exposing 6 mm of the roots out of the acrylic resin blocks. The specimens were divided into two experimental groups, according to NiTi rotary systems used and one control group (n = 20). After instrumentation, the specimens of both experimental groups were then filled using master Gutta-percha cones size 35 (0.04 taper) and obturation was done using continuous wave compaction technique. The specimens were kept at 37 °C and 100% humidity for 2 weeks to allow complete setting of the sealer. Root fracture resistance was assessed using a universal testing machine (Instron) and the amount of load necessary for root fracture was recorded in Newtons (N). Statistics: Data were collected, tabulated and statistically analyzed using one-way ANOVA test and Tukey’s posthoc test. Results: Group C (control) exhibited the highest mean fracture force (357.13 ± 20.61) while group A (SANI S3) showed the lowest mean fracture force (192.60 ± 22.73). One-way ANOVA test showed statistically significant differences between tested groups.

Mercury dental amalgam has been used as a dental restorative material for almost 200 years. Even though mercury is the most toxic non-radioactive material known to man, there has been an ongoing controversy about its safety since it was first introduced for use in dentistry. In 2013, a global treaty was adopted to address the dangers of mercury-containing products and processes called the Minamata Convention on Mercury Treaty, which went into force in 2017. This global mercury treaty listed mercury dental amalgam as a “phase-down” product. It is the only product in the treaty that is implanted in the human body and the only product listed simply as “phase-down”. While many evidence-based scientific papers have reported that mercury dental amalgam negatively affects human health, it is still the most commonly used dental restorative material in the world. Since the treaty has gone into force, many developed countries, countries with emerging economies, and developing countries have banned the use of mercury dental amalgam in the spirit of the treaty whose mantra is “Make Mercury History”. However, a date certain to ban mercury dental amalgam’s use globally has not yet been achieved. The latest significant findings on human exposure to mercury dental amalgam using the “Gold Standard” National Health and Nutrition Examination Survey (NHANES) database, may finally be the catalyst that will achieve the goal and “Make Mercury History” in the dental sector.

Introduction: The control of the bacterial load during an endodontic treatment is challenging; the usual chemomechanical procedures such as conventional needle irrigation (CNI) has not always shown satisfying outcomes. Hence, the necessity of finding complementary methods such as passive ultra-sonic irrigation (PUI), sonic activated irrigation (SAI) and laser assisted irrigation (LAI) in order to achieve the most complete disinfection of the endodontic system. The aim of our study is to systematically review and critically analyze the current evidence of the effectiveness of laser assisted irrigation when compared to CNI, PUI, SAI. Materials and methods: Electronic search on four data-bases: PubMed, Scopus, ScienceDirect and Cochrane Library was done looking for Systematic reviews, in-vitro and clinical controlled trials assessing the effectiveness of LAI in removing bacteria and dentine debris. Articles were selected, deduplicated than assessed. The studies that met all the inclusion criteria were included and were further screened in order to extract their data and evaluate their methodological quality. Results: The electronic search yielded a total of 895 potentially eligible record. After the final stage of selection, 25 studies, that are all in-vitro were included; the risk of bias and quality assessment was done through the Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the Joanna Briggs Institute critical appraisal Checklist. All in all, LAI showed better results when compared to CNI in both removal of bacteria and smear layer, yet when compared to PUI and SAI, the studies could not testify significantly for the superiority of an activation method over another. Conclusion: The use of LAI increased the potential of the irrigant within the endodontic system, especially when compared to CNI. Yet the current data could not give a conclusive judgment of the effectiveness of LAI when compared to PUI and to SAI; eventually further studies need to be performed.
