Objectives: This study aimed to evaluate the effects of different irrigation systems on the removal of intracanal medicament used in regenerative endodonti treatment. Materials and Methods: Following standardized preparation to obtain an immature tooth model, modified triple antibiotic paste (mTAP) consisting of metronidazole, ciprofloxacin and clindamycin was applied to the root canals of single-rooted human maxillar teeth and waited for three weeks. A total of 50 teeth with standardized preparation and intracanal medicament were randomly divided into five groups according to the irrigation method to be applied (n=10); Group 1: Conventional Syringe Irrigation (CSI), Group 2: Passive Ultrasonic Irrigation (PUI), Group 3: EndoActivator (EA), Group 4: EndoVac (EV) Group 5: Nd:YAG laser (LSR). Following the removal of the mTAP with different irrigation systems, the teeth were divided along their bukko-lingual axis. The impact roots were examined under the stereomicroscope with the 4-grade scoring scale for the presence of residual intracanal medicaments. Scores for coronal, middle and apical regions of each root were recorded. Results: In terms of total scores, PUI group showed higher intracanal medicament removal efficacy compared to the other groups (p

Objectives:Determination of molar coefficients of the chemical elements in dentin, their possible correlation with tooth enamel. Material and Methods:There were examined 29 clinically extracted teeth of both jaws and their longitudinal sections (12 clinically intact teeth, 10 teeth with wedge-shaped defects, 7 teeth with cervical caries) of the patients aged 25to 54 with the help of JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis. We have determined the chemical composition of 290 enamel areas and 235 dentine areas in the incisal region (tubercle), equator, cervical area as a percentage of the weight amounts of carbon, oxygen, calcium, phosphorus, sodium, magnesium, sulfur, chlorine, zinc, potassium, aluminum, we have identified their molar coefficients. Results: The chemical composition of dentin differed in the values of Na/Mg, Al/Zn, Mg/Ca, K/Na (p≤0.05) in all studied topographical regions of the samples. Higher values of Na/Mg and lower values of Al/Zn were identified in the teeth with cervical caries (p≤0.05). Correlation was found in dentin: inverse between Ca/P and P/Ca, Mg/Ca and Na/Mg, Ca/Mg and Mg/Ca, Mg/P and Na/Mg, Mg/P and Ca/Mg, direct between Ca/Mg and Na/Mg, Mg/P and Mg/Ca (p≤0.05). High correlation was determined between molar coefficients in enamel and dentin: Mg/Ca and Mg/P (direct), Ca/P and P/Ca (inverse), p<0.0001. Conclusions:The differences in the indicators of molar coefficients in dentin, their correlation with enamel are probably associated with the peculiarities of the pathological processes in the cervical region and it requires further study.

Objectives: Present study aimed to evaluate the roughening ability of different laser systems on the middle and apical third of roots. Materials and Methods: Sixty extracted human single-rooted single canal mandibular premolar teeth were randomly assigned to 3 groups (n=20). Standardized preparation and sterilization procedures were performed. The samples were irradiated with Er:YAG, Nd:YAG, and KTP laser systems. The laser irradiations (1.5 Watt) were applied with a spiral motion, starting 1 mm short of the apex and then moving coronally for 10 sec, interleaved with 15-sec recovery intervals for each irradiation. This process was repeated twelve times. The roots that were standardized in the same length and thicknesses were divided parallel to the longitudinal axis. Then, the middle and apical 1/3 surface roughness values of each root section were measured using a profilometer and SEM analysis was performed. The data obtained were analyzed using the two-way analysis of variance (ANOVA) and Tukey post-hoc tests. Results: According to measurements obtained from middle and apical 1/3 surfaces; Although, the statistically highest roughness value was determined after Nd:YAG laser (P < 0.05), the statistically lowest value was detected following the Er:YAG laser irradiation (P < 0.05). Conclusions: In light of the present study, all laser systems caused significant roughness surface. Therefore, laser systems should be carefully applied in human root canals.

Background: Pre-clinical removable prosthodontic training is an integral part of undergraduate curriculum. The objectives of the study were to evaluate the application of pre-clinical removable prosthodontic laboratory training in general dental practice and relevance of its teaching in undergraduate curriculum. Methods: A descriptive questionnaire was developed to assess the extent of practice of pre-clinical removable prosthodontic lab skills in their dental practice. The responses were evaluated and statistically analyzed with a significance value of p<0.05. Three hundred-fifty-seven general dental practitioners participated in the study. Results: 91% with 20 years of dental practice responded positively on the application of prosthodontic training in their practice. 55.7% with two years of training agreed to dedicate more time to clinical prosthodontics training. Conclusions: 52.9% of the respondents agreed that it would be better to dedicate more time on clinical prosthodontics training rather than pre-clinical removable prosthodontics lab training as a part of the undergraduate prosthodontic curriculum, among which more than 60% of the study participants had two or more years of removable prosthodontics pre-clinical training during dental school. Practical implications: Clinical expertise of dental graduate is an essential component in the general dental practice. Hence, there is a need to revisit removable prosthodontic curriculum content and time distribution in undergraduate dental program.

Objectives: The purpose of this study is the evaluation of the perspectives of the educators in Faculties of Dentistry with regard to online education. Materials and Methods: It was requested from the educators of the Faculties of Dentistry to fill in a questionnaire about their perspectives on online education including overall assessment statements. The questionnaire was delivered to the participants as a paper-based or online version. The data were evaluated using descriptive statistics and multiple logistical regression analysis (p < 0.05). Results: 350 valid responses were received by the educators over the course of 15 days. By means of our findings, we observed that the educators accommodate themselves to the online education on easy terms. However, fewer educators found online education advantageous over face-to-face education. In addition, during online education, it was mostly given a negative opinion as to students' class attendance, class participation, and learning success can be controlled or not. According to the results of the multiple logistical regression analysis, it was shown that the positive opinions of the educators in terms of their perspectives about online education can be increased with the increase in weekly course hours and the current technological infrastructure situation, and can be decreased with the increase in tenure. Conclusion: Our study shows that the perspectives of the educators with regard to online education were not positive in general. However, the results demonstrate that the perspectives of the educators for online education can change with various factors.

ABSTRACT Objectives: The drugs commonly used/prescribed by dentists/physicians or consumed by patients may cause adverse drug reactions (ADRs). Therefore, the possibility of dentists to encounter an ADR during their professional lives cannot be underestimated and the contribution of dentists to pharmacovigilance systems by notifying spontaneous ADR reports play an important role in the early detection and prevention of ADRs. This study aimed to assess the knowledge, attitudes and practices of dentists regarding pharmacovigilance and ADR reporting. Materials and Methods: A questionnaire with 30 questions evaluating knowledge, attitudes and practices of pharmacovigilance and ADR reporting among general dentists (GDs) and specialist dentists (SDs) was distributed electronically in northwestern region of Turkey. Data were statistically analyzed (p < 0.05). Results: Most of the participants were able to define the terms of pharmacovigilance (64.7%), ADR (74.9%) and side-effect (58.1%).

Class III malocclusions are usually related to growth and mandibular posture. The mixed dentition stage of development may provide a useful opportunity to embark upon orthodontic therapy to correct a Class III malocclusion. Chin cap is a useful appliance in growingpatients that exhibit mandibular prognathis. This case report aim to describe an early treatment of a Class III malocclusion by using a chincup. This case report presents a 9 year-old girl with a functional Class III malocclusion and anterior crossbite. She has treated by using chincup for 10 months. The occlusion was elevated with a maxillary appliance, and the maxilla was freed from the restriction of the mandible. In this way, the maxilla was able to continue its development and the growth of the mandible was limited by chincup. Anterior cross-bite was corrected and a positive overjet were achieved. Facial profile was improved. While posterior rotation of the mandible was expected with the effect of the chincup, SN-GoGn angle didn’t change in this case. At the end of treatment, a class I relationship and a smooth soft tissue profile were obtained.

Objetive: Assess the association of burnout with socio-educational variables in a sample of Chilean dental students. Material and methods: A cross-sectional study was carried out on dental students in their 4th/5th years of the University of Concepción, Chile. The sample size was estimated at 170 students. The following variables were considered: sociodemographic (sex, age, with whom the student lives and commune of origin), educational (course, course failure, number of years behind and their cause, number of career options, funding, and secondary school type), and Burnout-MBI-SS (Maslach's Burnout Inventory for students). To evaluate the association between the variables, descriptive statistics for quantitative were made using mean and standard deviation for normal distribution variables, and median and interquartile range for non-normal distribution variables; for categorical variables, frequency, and percentage distribution was calculated. Shapiro-Wilk test was used to assess normality, as non-normal distribution was verified for MBI-SS, Mann-Whitney and Kruskal-Wallis was used to estimate statistical differences amongst categorical variables, and Spearman for correlations (p < 0.05). Results: Most students were in 4th year, female with a mean age of 23. For the majority, dental school was their first option, and were studying with a scholarship. Most of them lived with their nuclear family and 58% had at least failed one course. Statistical significant correlations were only found for Depersonalization with students’ age (rho= 0.2420) and reprobation years (rho= 0.1838). Conclusions: Dental students from the University of Concepción, which are female, attending their fifth year, and students who failed courses, especially clinical ones, exhibit higher levels of burnout.
目的:评估智利牙科学生的职业倦怠与社会教育变量的关系。材料和方法:对智利Concepción大学4 /5年级的牙科学生进行了横断面研究。样本量估计为170名学生。考虑了以下变量:社会人口统计学(性别、年龄、与学生一起生活和原社区)、教育(课程、课程失败、落后年数及其原因、职业选择数量、资助和中学类型)和倦怠- mbi - ss(马斯拉奇学生倦怠量表)。为了评估变量之间的相关性，正态分布变量采用均值和标准差进行描述性统计，非正态分布变量采用中位数和四分位数范围进行定量统计;对于分类变量，计算频率和百分比分布。采用Shapiro-Wilk检验评估正态性，因为MBI-SS的非正态分布被验证，使用Mann-Whitney和Kruskal-Wallis来估计分类变量之间的统计差异，使用Spearman来评估相关性(p < 0.05)。结果:以四年级学生居多，女生，平均年龄23岁。对大多数人来说，牙科学校是他们的第一选择，他们拿着奖学金学习。他们中的大多数人与核心家庭生活在一起，58%的人至少有一门课程不及格。人格解体只与学生年龄(rho= 0.2420)和留校年限(rho= 0.1838)有统计学显著相关。结论:Concepción大学牙科专业的五年级女生和不及格学生，尤其是临床不及格学生表现出较高的职业倦怠水平。

Conclusions: Dental students from the University of Concepción, which are female, attending their fifth year, and students who failed courses, especially clinical ones, exhibit higher levels of burnout.","PeriodicalId":10781,"journal":{"name":"Cumhuriyet Dental Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43028435","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}

Objective: The study aimed to evaluate the variations in the RCM of mandibular first premolars (MFP) in south Indians and also evaluated the gender dimorphism and contralateral symmetry of the pattern. Methods: 200 Cone Beam Computed Tomography (CBCT) images of MFP of patients above 18 years were analyzed for the root canal morphology after excluding the distorted images, endodontically treated tooth or fractured root. The teeth were carefully evaluated in cross-sectional, axial and coronal sections and the information regarding the number of roots and the type of root canal as per Vertucci’s classification. Interobserver and intraobserver reliability were also checked. Results: Single rooted teeth with Type I (73.01%) variation was the most prevalent pattern observed in the study population, which was followed by Type III (14.11%) and Type V (5.52%), respectively. Type IV and Type VIII variations were not found in our study. Conclusions: In both males and females, type I configuration was the most common pattern with symmetry in contralateral mandibular single-rooted first premolars.
