Objective. The introduction of CAD/CAM and the development of zirconia-based restorations have allowed clinicians to use less expensive materials and faster manufacturing procedures. The purpose of the study was to analyze the differences, in terms of mechanical and biological complication, in multiunit zirconia fixed dental prosthesis (FPDs) on posterior implants produced using a digital workflow. Method and Materials. This study was a retrospective investigation, and patients treated with screw-retained monolithic or partial veneer FPDs on dental implants were selected. Periapical radiographs were taken at baseline and at the 3-year follow-up. Complications were recorded and classified as technical and biological ones. Results. The study population included 25 patients. The occlusal and interproximal corrections were not clinically significant. In the study sample, the survival rate and success rate of the FPDs after 3 years were 100% and 96%, respectively. One implant failed immediately after placement. Conclusion. Monolithic zirconia FPDs and partial veneer FPDs showed a 100% survival rate, presenting an interesting alternative to metal ceramic restorations. The partial veneer FPDs had a higher technical complication rate than the monolithic FPDs; however, no statistically significant difference was found.

Abstract Background Influenza vaccination (IV) is recommended for elderly but vaccination coverage in this group remains unsatisfactory in Croatia. The aim of this study was to explore IV uptake among elderly from Eastern Croatia and predictors that influence this uptake. Methods This cross-sectional questionnaire study was conducted during 2018/2019 influenza season in convenient sample of older adults aged 65 years or more from Eastern Croatia at the primary health care setting. Results The study sample consisted of 816 subjects (48.0% males and 52.0% females). The median age of all subjects was 73.0 years (interquartile range (IQR) 69.5 - 79.0 years). The overall prevalence of IV uptake was 33.3%. The IV uptake was statistically more frequent among females (P < 0.001) and old-old subgroup (85 years and older) (P < 0.001). There was no statistically significant difference in IV uptake considering marital status of subjects (P > 0.999). The median number of positive attitudes towards IV was 4.0 (IQR 2.0 - 4.0) and the median number of correct answers was 6.0 (IQR 4.0 - 8.0). The study revealed fair positive correlation between attitudes and IV uptake (rho=0.477; P < 0.001) and poor positive correlation between knowledge and IV uptake (rho=0.242; P < 0.001). The study further showed poor positive correlation between presence of comorbidities and IV uptake (rho=0.187; P < 0.001) and moderate positive correlation between previous year vaccination history and IV uptake (rho=0.669; P < 0.001). Conclusions The study showed that observed IV uptake is far below EU target influenza vaccination coverage among elderly of 75%. The study revealed that fairly good predictors of IV uptake in study population were gender, older age group, and previous year vaccination history while attitudes, knowledge and presence of comorbidities were fairly poor predictors. The good predictors of IV uptake among elderly should be taken into account during influenza vaccination popularization strategies development. Key messages Understanding the factors that could improve the acceptance of vaccination is crucial to design effective public health interventions. The structured communication campaigns on influenza and influenza vaccines should be developed and directed specifically to elderly as one of target groups for vaccination.

Abstract Background Quantitative and qualitative analysis of several periodontal parameters plays an important role in several dental procedures. Aim of the current study was to assess gingival thickness (GT) at mandibular incisors of orthodontic patients with two methods and determine how these methods are compared to each other when assessing periodontal anatomy through soft tissue thickness.Methods The sample consisted of 40 consecutive adult orthodontic patients. GT was measured at both central mandibular incisors, mid-facially on the buccal aspect, 2mm apically to the free gingival margin with two methods: a) clinically with an Ultrasound device (USD) and b) radiographically with Cone Beam Computed Tomography (CBCT).Results CBCT measurements were consistently higher than USD measurements, with the difference ranging from 0.13 mm to 0.21 mm. No difference was noted between the repeated CBCT measurements at the right central incisor (Bias= 0.05 mm; 95% CI= -0.01, 0.11, p=0.104). Although the respective results for the left incisor indicated, statistically, that the measurements were not exactly replicated, the magnitude of the point estimate was small and not clinically significant (Bias= 0.06 mm; 95% CI= 0.01, 0.11, p=0.014). Small differences between CBCT measurements made by the 2 examiners at the left central incisor (bias= 0.06 mm, 95% CI= 0.01, 0.11, p=0.014) were detected. However, this difference was minor, and again, not clinically significant. The respective analysis on the right incisor showed no significant difference (bias= 0.05 mm, 95% CI= -0.01, 0.11, p=0.246).Conclusions Present data indicate that CBCT measurements were highly reproducible and yielded greater values compared to USD measurements.

Objective. To compare prostate cancer detection rates (CDRs) and pathology results with targeted prostate biopsy (TB) and systematic prostate biopsy (SB) in biopsy-naive men. Methods. An in-patient control study of 82 men undergoing SB and subsequent TB in case of positive prostate MRI between 2015 and 2017 in the Jeroen Bosch Hospital, the Netherlands. Results. Prostate cancer (PCa) was detected in 54.9% with 70.7% agreement between TB and SB. Significant PCa (Gleason score ≥7) was detected in 24.4%. The CDR with TB and SB was 35.4% and 48.8%, respectively (p=0.052). The CDR of significant prostate cancer with TB and SB was both 20.7%. Clinically significant pathology upgrading occurred in 7.3% by adding TB to SB and 22.0% by adding SB to TB. Conclusions. There is no statistically significant difference between CDRs of SB and TB. Both SB and TB miss significant PCas. Moreover, pathology upgrading occurred more often by adding SB to TB than vice versa. This indicates that the omission of SB in this study population might not be justified.

<p><strong>BACKGROUND: </strong>One of the features that any profession possesses is that it occupies a social status relative to other professions. The present paper contributes to the discussion on the relationship between nursing occupational prestige and social health.</p><p><strong>METHOD:</strong> This study was a cross-sectional research that was conducted in 2015. The study population consisted of 200 staff nurses working in all hospitals located in Hamedan, Iran. A convenience sampling was employed to select 200 nurses who were asked respond to the 25item Keyes’s Social Health Questionnaire and the16-item Nursing Occupational Prestige Questionnaire. Higher score reflected better social health and occupational prestige. The quantitative analysis of this study was carried out using the Statistical Package for Social Science (SPSS).</p><p><strong>RESULTS:</strong> The results showed that the nurses’ mean score of social health and nursing occupational prestige were respectively 43.88±9.18 and occupational prestige44.83±25.14. Social health was significantly related to occupational prestige in the nurses (r=0.15, P=0.04). 66.5% of the nurses were reported to have average occupational prestige and 75.5% of them were believed to have average social health. There was a statistically significant difference in scores of the occupational prestige among the nursing post (P=0.01), job satisfaction (P&lt;0.001) and job interest (P=0.007).</p><p><strong>CONCLUSION:</strong> Nurses’ social health deserves special attention. Effective social health promotion strategies should be considered for promoting their social health particularly in occupational prestige.</p>

Purpose: To investigate the distribution of white-to-white (WTW) corneal diameter and anterior chamber depth (ACD) in Chinese myopia patients.Methods: This was a cross-sectional observational study conducted at five ophthalmic centers. Anterior segment biometry was performed in 7,893 eyes of the 7,893 myopic patients using Pentacam, and the WTW and ACD were recorded. The distribution patterns of WTW and ACD were evaluated and the correlation between WTW and ACD was analyzed statistically.Results: There were 4416 (55.95%) males and 3477 (44.05%) females. The age of the study population was 25.14 ± 5.41 years. Distribution of WTW was slightly positively skewed (Skewness = 0.0076, Kurtosis = 0.3944, KS P = 0.020) with a mean of 11.65 ± 0.38 mm and a 95% normal range of 10.91–12.39 mm. A significant difference in WTW was found among different myopia groups (P &lt; 0.001). The ACD was normally distributed (Skewness = 0.899, Kurtosis = 0.027, KS P = 0.086). The mean ACD was 3.25 ± 0.26 mm and the 95% normal range of was 2.74–3.75 mm. A significant difference in ACD was also found among different myopia groups (P = 0.030). There was a significant correlation between WTW and ACD (r = 0.460, P &lt; 0.001).Conclusions: In our study, 95% of the Chinese myopic patients had a WTW within 10.91–12.39 mm and an ACD within 2.74–3.75 mm. ACD and WTW were significantly different among different myopia, gender and age groups. WTW was positively correlated with ACD.

Introduction: Fish is one of the sources of animal protein that many people look for because it is readily available and affordable. Nowadays, found in many traditional markets of traders, fish managers use formalin to preserve their wares. Objective: The purpose of this study was to determine differences in levels of boiled and fresh fish in TPI Tulungagung. Design quantitative analytic research studies cross-sectional. Quantitative formalin test with Formalin Kit returns UV-Vis spectrophotometer in the Biomedical Laboratory FK UMM, and Mann-Whitney test. The study population of fresh and boiled fish taken from 3 TPI in Tulungagung. The sampling technique was random sampling, each with four samples. Result: The results showed that the average value of formalin in boiled fish was 1.63 mg / ℓ and fresh 4.54 mg / ℓ. There was a significant difference in formalin levels in boiled fish and fresh fish (p) <0.001. The samples from TPI Tulungagung contaminated formalin. However, the content of formalin in fresh fish is higher than boiled fish. It is very high from the BPOM standard. Discussion: The public is more concerned with the abuses committed, especially the use of formalin in circulation.

Abstract Background: Molar incisos hypomineralization (MIH) has serious impact on oral health-related quality of life for a child, due to its effects on tooth structure, aesthetics and behavior of the child. The current study was designed to determine the prevalence, pattern and distribution of MIH in school children in Sudan.Methods: This was a descriptive, cross-sectional study involving 568 children, aged 8-11 years from schools in Khartoum State. After collecting their socio-demographic data, the children were examined for hypomineralization on the 12 MIH indexed teeth, and assessed on the MIH pattern and distribution. The data collected were analyzed to obtain descriptive statstics, and the results related to the socio-demographic and other dental-related factors of the children using chi-square test and Spearman Rank Correlation, with the significant level set at p<0.05.Results: The prevalence of MIH in the study population was 20.1%. Majority of the affected teeth were permanent first molars (PFMs) (12.5%), but there was no statistical significant difference between the occurrence of hypomineralization on mandibular and maxillary molars (p=0.22). However, in the case of incisors, there was a statistical significant difference between the maxillary incisors that had higher hypomineralization rate when related to the mandibular incisors ( p=0.00). In terms of the pattern of hypomineralization, demarcated opacities were the commonest MIH defects (69.9%) in the study group.Conclusions: While the prevalence of MIH in the study population was 20.1%, both molars and incisor teeth were frequently affected in both dental arches, and the demarcated opacity type were the most frequent form of defect found in the teeth of the participants.

Introduction: Minor oral surgical procedures are practiced in dental teaching. Interns are required to be competent, well-prepared and acknowledge its basics before their practice. Lack of training and knowledge could lead to serious consequences during clinical practice. Aim: To assess the knowledge and confidence level between male and female dental interns in private and governmental Riyadh dental schools in performing simple dento-alveolar procedures. Materials and Methods: A cross-sectional observational study was conducted at Princess Nourah bint Abdulrahman University in Riyadh, Saudi Arabia in January 2020 among dental interns from all Riyadh dental schools. A cross-sectional survey containing 23 items was used. The first part included the informed consent and demographic data (item 1-3). The second part consisted of 10 case scenarios to assess the knowledge level (item 4-13), and the third part was developed to self-rate their confidence level (item 14-23). Around 300 participants belonging to five Riyadh dental schools comprised the study population. All interns were included in the study after obtaining informed consent. All statistical analyses were performed using Statistical Package for the Social Sciences (SPSS) version 21.0 and Microsoft Excel 16.16. Groups were compared using Pearson chi-square and unpaired sample t-test. The p-value of <0.05 was considered statistically significant. Results: Out of 300 interns invited to participate, 210 submitted the electronic survey (70%). The final study population included 117 (56%) females and 93 (44%) males. A total of 111 (53%) belonged to governmental college, and 99 (47%) belonged to private college. There was no statistically significant difference between females and males in total knowledge (p<0.272) and confidence score (p<0.850), respectively. However, a statistically significant difference in knowledge and confidence between government and private colleges was found (p<0.001). A weakly positive significant correlation (r=0.217, p=0.002) was found between the total score of knowledge and the total score of confidence in performing surgical procedures. Conclusion: The study provides baseline data on the knowledge and perceived confidence of dental interns in Saudi Arabia about certain clinical procedures in oral surgery, where respondents were most knowledgeable in prescribing an appropriate medication. They were confident in giving effective local anaesthesia. All in all, interns had a superficial knowledge about the classification of impacted teeth and they were least confident in managing cases of an intraoral abscess.
