Indications For Use

Introduction. Vast indications for use of the polymer resins in cavity reconstruction result from a progress in manufacturing process. A new group of cross-infection control restoratives provide sterility of the treatment together with fulfillment of both the patients and the dentists requirements. A disposable packaging enables usage of the material’s portion to restore a single lesion and prevents its further re-use. Aim. The aim of the study was to compare clinical features, such as application, modelling, polishing and esthetics, of a restorative material packed in blisters to other polymer restorative materials. Material and methods. A survey study was conducted among 56 students of dentistry. They were given a blister of the material and asked to use it for restoration of a chosen cavity. Afterwards, they were asked to fill in a questionnaire concerning the clinical work with the material. All returned data was analyzed with chi-square test at p < 0.05. Results. The overall responsive rate was 44.6%. Taking the material from the blister was comfortable for 84%. The material’s application in the cavity was estimated well by 92% of the respondents. 72% believed its application and polishing was significantly easier than the other materials. 72% of the students claimed the material was more esthetic than the other restoratives. Conclusions. The restorative material packed in blisters is comfortable to apply in the cavity, can be easily modelled and polished. Blisters are comfortable to use by the dentist and the assistant. Due to high esthetics, it is dedicated for esthetic restorations.

Mandibular Third Molars

Introduction: Racial variation, genetic inheritance and various other factors can affect the jaw size and ultimately the tooth size and number. Studies for agenesis of mandibular third molars (M3s) have been carried out in various populations but data relating to these are not evident from most of the parts of Nepal. Hence, the objective of the present study is to determine the prevalence of agenesis among the population of patients visiting the Department of Oral Medicine and Radiology of this institute. The study also sought the odds of agenesis of M3 in one side when there was missing M3 on the other side of the mandible. Methods: This study was conducted after the approval from Institutional Review Committee of BPKIHS. Two hundred and eighty four patients (568 sites of M3, bilaterally), visiting the Department of Oral Medicine and Radiology were studied with Panoramic Radiograph to assess for agenesis of mandibular third molars, bilaterally. Percentage of agenesis was calculated and chi square test was applied where relevant. Odds ratio was also calculated. Results: Agenesis was seen in 28.7% of the participants. The Odds of M3 being missing on one side with concurrent missing M3 on the other side was 40.27 (Confidence Interval 19.34 to 83.87). Conclusions: Agenesis was highly prevalent in this study group. The likelihood of M3 being absent on one side, when there was concurrent missing M3 on the other side of mandible was also high.

Abstract Objective: To analyze the prevalence, distribution, clinical features, and relationship with dental anomalies of maxillary canine impaction. Materials and Methods: The complete pretreatment records of 1674 orthodontic patients were examined. Subjects with maxillary impacted canines were divided into two study groups: a palatally displaced canine (PDC) group (114 patients) and a buccally displaced canine (BDC) group (37 patients). These were compared to a control group of 151 patients who were randomly selected from the initial sample without maxillary canine impaction. The significance of associations between canine impaction and dental and clinical features and anomalies was examined with the chi-square test. Results: PDC patients presented with normal overjet and facial profile and a lower degree of dental arch crowding in comparison to the control patients. PDC patients showed a higher prevalence of impaction of other teeth, dental aplasia, transposition, and peg-shaped maxillary lateral incisors (odds ratios 3.3, 2.6, 8.3, and 5.8, respectively). Conclusion: PDC was frequently the only orthodontic problem of patients. BDC group patients did not present with notable differences in clinical and dental features or dental anomalies compared to control subjects.

Objectives The purpose of the current study was to evaluate the analytical performance of seven kits for detecting IgM/IgG antibodies against coronavirus (SARS-CoV-2) by using four chemiluminescence immunoassay systems. Methods Fifty patients diagnosed with SARS-CoV-2 infection and 130 controls without coronavirus infection from the General Hospital of Chongqing were enrolled in the current retrospective study. Four chemiluminescence immunoassay systems, including seven IgM/IgG antibody detection kits for SARS-CoV-2 (A_IgM, A_IgG, B_IgM, B_IgG, C_IgM, C_IgG and D_Ab), were employed to detect antibody concentrations. The chi-square test, the receiver operating characteristic (ROC) curve and Youden’s index were determined to verify the cut-off value of each detection system. Results The repeatability verification results of the A, B, C and D systems are all qualified. D_Ab performed best (92% sensitivity and 99.23% specificity), and B_IgM performed worse than the other systems. Except for the A_IgM and C_IgG systems, the optimal diagnostic thresholds and cut-off values of the other kits and their recommendations are inconsistent with each other. B_IgM had the worst AUC, and C_IgG had the best diagnostic accuracy. More importantly, the B_IgG system had the highest false-positive rate for testing patients with AIDS, tumours and pregnancies. The A_IgM system test showed the highest false-positive rates among elderly individuals over 90 years old. COVID-2019 IgM/IgG antibody test systems exhibit performance differences. Conclusions The Innodx Biotech Total Antibody serum diagnosis kit is the most reliable detection system for anti-SARS-CoV-2 antibodies, which can be used together with nucleic acid tests as an alternative method for SARS-CoV-2 detecting.

ABSTRACT Objective To compare the level of satisfaction in the use of wraparound Hawley and thermoplastic maxillary retainers. Materials and Methods The study sample included 70 orthodontic patients (24 males and 46 females), who were in the retention stage (mean age = 20.80 years). All patients wore the two types of maxillary retainer for 1 month each, along with a 3×3 fixed mandibular retainer. After the use of each retainer, the patients responded to a questionnaire evaluating the level of satisfaction with their use of the maxillary retainer. Intergroup comparison was performed by independent t tests. Chi-square test was used to evaluate preference for the type of retainer by gender. Results The thermoplastic retainer was better for swallowing and the wraparound Hawley appliance was better for hygiene and durability. The other factors evaluated (adaptation, speech, comfort, esthetics, satisfaction, and fitting) did not show significant differences between the retainers. There was also no significant difference in preference for the appliances. Conclusions Regarding the overall satisfaction and the preference, there was no difference between the wraparound Hawley and thermoplastic retainers. The wraparound Hawley appliance was better in hygiene and resistance than the thermoplastic retainer; and the thermoplastic appliance was better than the wraparound Hawley for swallowing fluids and saliva.

Introduction: Musculoskeletal Disorders (MDs) largely contribute to occupational diseases in the workplace. Prevention from these disorders requires their evaluation in different occupations. This study aimed to compare the MDs of the neck between the teachers of Physical Education (PE) and those of the other majors in the high schools of Tehran City, Iran. Methods: The study sample included 180 teachers of mathematics, PE, and the religion and lifestyle in the high schools of Tehran (with the Mean±SD age of 42.11±6.65 years, and the Mean±SD weight of 72.28±12.98 kg). The participants were selected from 19 districts of the Tehran Departments of Education using multistage cluster sampling. The standard Nordic questionnaire was administered to investigate MDs among the teachers. The obtained data were analyzed with the Chi-square test to compare the MDs of the neck between the three groups of teachers. Results: A significant relationship was observed between the neck problems of the female (P=0.016) and male (P=0.017) PE teachers and the other teachers. Moreover, the neck problems were associated with the teaching experience (P=0.024) and teaching major (P=0.004). Conclusion: Based on the results, it seems that regular exercise can reduce the developing risk of MDs in the neck. Thus, this study recommends the performance of regular exercise and the correction of job-related postures to all teachers.

Private mortgage lending business is an important business segment for retail banks. There are two main reasons for this. Firstly, the comparatively low risk. On the one hand, because many years of experience in this segment enable optimal risk management. On the other hand, the financed properties also provide optimum security. Due to the small size of this business segment, private construction financing was unattractive for major banks for a long time. On the other hand, this division was a core business for regional banks and savings banks. However, as a result of the banking crisis in 2007 and 2008 and the ECB’s ongoing low-interest policy, the private mortgage lending sector is now attractive to all market participants. This is reflected in fiercer competition. The importance of customer communication has therefore also increased in the advertising for new business. Since financial and personnel resources are limited, corporate communications are faced with the challenge of addressing potential customers as efficiently as possible. Communication science has already developed a number of concepts for optimal, integrated communication. These are based on average consumers. Against the background of possible regional deviations in media usage and consumer behaviour, this work explains that banks and savings banks with a regionally defined business area should set different priorities within the communications mix than suprare­gional providers. To this end, a field study was conducted in rural areas of the Nuremberg metro­politan region and analysed using a chi-square test. The study revealed the continuing importance of branches and personal advice, despite increasing digitalisation. At the same time, the necessity of closely networking stationary sales and online offers in rural areas becomes clear.

Special Care Dentistry (SCD) or Special Needs Dentistry is a branch of dentistry concerned with the oral health of people with a variety of medical conditions or limitations that require more than routine delivery of care. There were reports on oral status of special care patients and special interest group for SCD dentists in Indonesia has existed. However, there was not perception report on SCD amongst dentists in Jakarta. This paper will describe the perception of dentists in Jakarta towards SCD. A cross-sectional questionnaire, translated and cross adapted to Indonesian, was distributed online through Whatsapp to dentists registered in Jakarta late 2019. Quantitative data was analyzed using statistical software for proportion and correlation using Chi-Square test. The questionnaire explored dentists’ perception towards SCD. A total of 250 dentists participated in this study, of them 173 general practitioners and 77 specialist dentists. Most respondents reported that they did not have SCD component during undergraduate dental school and did not provide treatment to patients with special needs in their clinical practice. Most respondents have poor perception of SCD, however, most of the respondents showed motivation and interest towards SCD training. Dentists in Jakarta involved in this study had poor perception of SCD. More efforts should be performed to improve SCD education and awareness.

The are many causes of nutritional problems, including lack of food intake, illness, caring pattern and many other causes, one of the problems that often happen is the children had not weighed regularly. Iodine is one of the nutrients associated with the growth of children. On the other hand, children who are suffering from malnutrition usually also hasVitamin A defi ciency as a result of their lack of nutrient intake. The purpose of this study was to analyze the relationship between the frequency of weighting, the use of iodized salt, and Vitamin A supplementation with underweight among children under fi ve in East Java Province. This study was secondary data analysis from Monitoring of Nutritional Status (MNS) in East Java, 2016. The sample of this study were 10.440 households with children under fi ve. 18.5% children under fi ve in East Java were underweight, 2% overweight, and 79.5% were normal. Distribution of frequency were performed as univariate statistical analysis and the relationship between variables were analyzed by chi-square test. The odd ratio were analyze by logistic regression. There was signifi cant correlation between blue-colored vitamin A supplementation (p < 0.001;OR = 0.638;95%CI:0.580-0.78w2) with underweight. However, there was no correlationbetween weighing frequency (p = 0,729) and the use of iodized salt (p = 0,620) with underweight. The conclusion of this study highlight that there was correlation between Vitamin A supplementation with underweight in East Java.
