Working Status

The super-aged society of Japan is experiencing an increased demand for dental hygienists, of which there is currently a shortage. This study aimed to investigate the factors related to the working status of dental hygienists in Japan. We conducted a survey by mailing a questionnaire on employment to 1444 dental hygienists and obtained 537 valid responses. We conducted a bivariate analysis using either a chi-square test or t-test as well as a multiple logistic regression analysis to determine the factors related to working status. The overall employment rate was 68.2%, with a significant difference between age groups (p < 0.01). Approximately 80% of respondents considered working hours and human relations at the workplace to be important, and more than 70% of respondents considered wages as important. Finally, the following four variables were found to be significantly associated with employment status: training course attendance, a desire to work full-time, consideration of wages as important, and consideration of working hours as important. These findings suggest that it is necessary to improve working conditions and environments, including wages and working hours, as well as provide a more robust system of continued professional development for dental hygienists to increase the workforce.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

Introduction: Motor Performance (MP) in children is an important resource for their future active lifestyle and health. Monitoring of MP is crucial to derive information of trends and to implement specific programs on the base of current MP levels. A variety of MP assessment tools exist, making it difficult to determine a “gold-standard” for assessment and to compare the findings. In Germany, the German Motor Test 6–18 (GMT 6–18) and Kinderturntest Plus 3–10 (KITT+ 3–10) are widely used MP assessment tools. The aim of this paper is to show which key questions can be answered within the context of a best practice example of a MP assessment tool and what can be derived from this for a practical application (the Fitness Barometer).Methods: The raw data of the Fitness Barometer was collected with the MP assessment tools GMT 6–18 and KITT+ 3–10 from 2012 through 2020. Data was pooled anonymously with the e-Research infrastructure MO|REdata and categorized into percentiles for MP and BMI. Overall, we included data of 23,864 children for the statistical analyses. T-tests for independent samples, percentage frequency analysis, descriptive statistics (chi- square-test) and single analysis of variance were conducted.Results and Discussion: Children tested reached a mean value of 57.03 (SD = 18.85). Of the sample, 12.7% children were overweight or obese and there is a significant difference between age groups [χ(4)2 = 178.62, p &lt; 0.001, Cramer V = 0.09; n = 23.656]. The relationship between BMI category and mean value of MP was significant [F(4,19,523) = 224.81, p &lt; 0.001]. During 2020, the year of the COVID-19 pandemic, mean value of endurance and speed decreased [Welch's F(1,573) = 8.08, p = 0.005; Welch's F(1,610) = 35.92, p &lt; 0.001]. The GMT 6–18 and KITT+ 3–10 are valid, objective, reliable, and economic MP assessment tools for monitoring MP levels and derive added practical value. Specific programs and interventions should focus on the findings of these. The Fitness Barometer is a best practice example how a standardized assessment tool of monitoring MP point to trends on which practical evidence-based suggestions can be derived with many various partners and expertise.

Objective: To evaluate molar-incisor-hypomineralization (MIH) prevalence, clinical characteristics, and severity amongst school children in Riyadh, Saudi Arabia. Subjects and Methods: Randomly selected, healthy third- and fourth-grade students (aged 8–10 years) attending elementary schools in Riyadh, and children of the same age attending dental clinics at the College of Dentistry, King Saud University, were examined for the presence of MIH, its clinical characteristics, and severity. Results: The sample studied consisted of 924 children, 447 (48.4%) of whom were boys. There were 376 children, (199 females and 177 males), with at least 2 index teeth affected (prevalence = 40.7%). A total of 133 (35.4%) had only molar hypomineralization (MH), whereas 243 (64.6%) had molars and incisors involved (MIH). The mean number of affected teeth per child was 6.6 ±3.6 (3.3 for molars and 3.2 for incisors). The chi-Square test showed no association between the distribution of hypomineralization and age (P = 0.115). Children with severe hypomineralization predominated across all age groups, with the 10-year-old group having more severely affected children (71.9%)  compared to 8- and 9-year-old groups (P = 0.000).  Proportional t-test showed no statistically significant difference (P>0.05) between males and females in the occurrence of MH or MIH, and in the severity of the hypomineralization. Upper molars were more affected than lower molars, whilst upper incisors were more affected than lower incisors. Conclusion: Enamel hypomineralization is a common feature in the dentition of 8–10-year-old children in Riyadh, Saudi Arabia. There is no association with age and no gender predilection.

Study Design: Cross section, comparative study. Place and Duration of Study: The study was carried out at the Department of Biochemistry of Quaid-i- Azam University, Islamabad from October 2014 to August 2015. Materials and Methods: In this study, 292 diagnosed patients HNSCC and 324 normal individuals without any history of cancer were enrolled. Blood samples of patients and controls were collected in ethylenediamine tetra acetic acid (EDTA) and DNA was extracted using conventional method. All samples were genotyped for the MTR A2756G polymorphism using PCR-RFLP. Frequency of polymorphism was compared between HNSCC patients andcontrols. MultipleLogisticRegression(MLR)andchi-squaretestwasperformedtoexaminetheassociation of MTR A2756G polymorphism with risk factor. Results: Chi-square test of independence showed statistically significant difference among the variables of age, smoking and MTR A2756G genotype (p-value<0.05). Multivariate analysis showed that smoking (adjusted OR, 3.7; 95% CI, 2.3 – 6.0), age groups 41 – 50 years (adjusted OR, 3.6; 95% CI, .9 – 6.7) and > 60 years (adjusted OR, 3.5; 95% CI, 1.7 – 7.3), MTR 2756 AG genotype (adjusted OR, 2.1; 95% CI, 1.3 – 3.5) is associated with increased risk of HNSCC. Conclusion: The results suggest that the genetic polymorphism MTR A2756G is associated with the occurrence of HNSCC in the Pakistani population while the individuals between 40 to 50 years of age and those who are smokers are at a greater risk of developing HNSCC.

Background: Hypospadias is the most common congenital malformation of the urethra with the prevalence of 1 in 200-300 live male births. The objective of this trial was to compare the frequency of urethrocutaneous fistula between Snodgrass and two staged Aivar Bracka repair of distal penile hypospadias in male children. Material & Methods: This RCT was conducted in Department of Plastic & Reconstructive Surgery, Hayatabad Medical Complex, Peshawar, Pakistan from 1st June 2013 to 31st May 2014. 64 male patients were randomly allocated to two surgical procedures, 32 to experimental (Snodgrass) group and 32 to control (two stage Aivar Bracka) group. Age in years, age groups and presence of urethrocutaneous fistula were variables. Age in years was analyzed by mean, SD and range and other variables by count and percentage. McNemar chi-square test was applied to see the significance of difference between the experimental and control groups in terms of frequency of urethrocutaneous fistula at alpha 0.05. Results: Mean age in experimental (Snodgross) group was 6.74 years±1.26 & in control (Aivar Bracka) group 6.71 years ±1.29. The urethrocutaneous fistula was present in three (9.38%, 80% CI 2.77-15.99%) cases in experimental (Snodgross) group and in six (18.75%, 80% CI 9.91-27.59%) cases in control (Aivar Bracka) group. McNemar chi-square test showed no significant difference between the experimental and control groups in terms of frequency of urethrocutaneous fistula. Conclusion: The results are comparable for Snodgrass repair and two stage Aivar Bracka repair for distal penile hypospadias in male children in terms of frequency of urethrocutaneous fistula in our population.
