Abstract One of the main goals of prosthetic dentistry is to reconstruct the masticatory system. Replacing missing teeth by complete or partial denture is associated with decreased bite force and patient satisfaction. The aim of the present study was to measure the maximum bite force (MBF) and to evaluate patients' satisfaction from their conventional complete dentures and their mandibular implant-supported overdentures opposed by complete denture. In this cross sectional analytical descriptive study, seventy-five 45- to 65-year-old patients were divided into 3 groups wearing: (1) conventional complete dentures for up to 6 months; (2) conventional complete dentures for 10 years or more; and (3) complete maxillary dentures opposing mandibular implant-supported overdentures. Bite force was measured by means of electronic bite force measuring device with strain gauges. Three measurements were made on each side on the first molar region and the mean values were recorded. Patient satisfaction was also recorded using questionnaires. Results were analyzed by analysis of variance (ANOVA), t test, chi-square, and Pearson correlation test. The mean MBF for the first, the second, and the third group was, respectively, 5.65 ± 1.46 kgf, 7.01 ± 2.1 kgf, and 12.22 ± 27 kgf. The difference between MBF in patients with overdentures and in patients with conventional complete dentures was statistically significant (P  =  .001). Patient satisfaction with mandibular implant-supported overdentures was recorded as “great.” Results indicated MBF in the patients with mandibular implant-supported overdentures was significantly higher than that of patients with conventional complete dentures. This difference may indicate the important role of dental implants in the improvement of bite force and chewing efficiency and therefore patients' satisfaction.

As Medical university of Isfahan is one of the leading universities of the country the results of this study could be very important for the use of other health systems in different states of country. This research aimed to assess the patients’ satisfaction of the booking appointment system services of Isfahan dentistry faculty, considering its different types of booking systems and patient satisfaction. Methods: The study was descriptive and cross-sectional. The questionnaire was prepared using Zhang study in 2014 and the standard Forward-Backward translation method. In order to investigate the validity, the opinions of the professors of Isfahan Dental School were taken and the professional opinions of the individuals were applied. The questionnaire was distributed among patients referring to the dental school who had undergone the initial examination. After completing the data, SPSS software version 20 and descriptive and analytical statistical tests were used to analyze the data (a = 0.05).Results: In this study, independent t-test, Kruscal-Wallis test and Pearson correlation test were used to investigate the data. The Kruscal-Wallis test showed that overall satisfaction was significantly higher in patients who booked appointment online than in other patients (P = 0.003). The independent t-test showed that the mean scores of patient satisfaction with staff behavior (P = 0.03) and satisfaction with the waiting time (P = 0.01) were significantly different between native, non-native and passenger patients.Conclusion: Most of the people surveyed were generally relatively satisfied with the booking appointment services. Most of them surveyed came in person to queue. Most people cited cheap services as the main reason for their visits. Most people cited telephone busy signal as the reason for not using the telephone booking system.

Objective: To determine the mean satisfaction score for patients with complete dentures and to compare the mean satisfaction score of patients with complete dentures and without past denture experience. Study design and Setting; It was a cross-sectional study conducted at Watim Dental College, Rawalpindi, from March to August 2018. Methodology: A total of 98 patients were selected and were asked regarding previous history of denture usage and their experience with the new set of dentures; in terms of function, comfort, appearance and total satisfaction. As a protocol all patients presenting to outpatient department and those patients who fulfilled the criteria were referred to Prosthodontic department for provision of complete dentures by specialist prosthodontist. Data was analysed using SPSS version 20. Descriptive statistics were calculated for both qualitative and quantitative variables. For qualitative variables like gender frequency and percentages was calculated. For Quantitative variables like age, score of function, comfort, appearance and total satisfaction mean and standard deviation were calculated. Mean± SD was calculated for satisfaction score among patients with and without past experience of denture usage. Independent sample t-test was used to compare quantitative variables. P values of less than 0.05 was considered significant. Results: Mean score of function, comfort, appearance and total satisfaction was greater among the patients with past denture experience as compared to new denture wearers with no past experience of denture wearing. Conclusion: Past denture experience has significant effect on patient satisfaction with their new complete dentures

Implant-supported prostheses hygiene and peri-implant tissues health are considered to be predictive factors for successful prosthetic rehabilitation. Therefore, the purpose of this study was to evaluate the effectiveness of brushing associated with oral irrigation measured as biofilm-removing capacity, maintenance of healthy oral tissues, and patient satisfaction. A randomized, crossover clinical trial was conducted with 38 patients who wore conventional maxillary complete dentures and mandibular overdentures retained by the O-ring system. The patients were instructed to use the following hygiene methods for 14 days: mechanical brushing [MB (brush and dentifrice - Control)]; and MB with oral irrigation [WP (Waterpik - Experimental)]. Biofilm-removing capacity and maintenance of healthy oral tissues were evaluated by the Modified Plaque Index (PI), Gingival Index (GI), Probing Depth (PD), and Bleeding on Probing Index (BP) recorded at baseline and after each method. In parallel, patients answered a specific questionnaire using a Visual Analogue Scale after each hygiene method. Data were analyzed by Friedman and Wilcoxon tests (α=0.05). The results showed significantly lower PI, GI, PD, and BP indices after application of the hygiene methods (P&lt;0.001) than those observed at baseline. However, no significant difference was found between MB and WP. The satisfaction questionnaire responses to both methods showed high mean values for all questions, with no statistically significant difference found between the answers given after the use of MB and WP (P&gt;0.05). The findings suggest that WP was effective in reducing PI, GI, PD, and BP indices and provided a high level of patient satisfaction.

Background: Periodontal disease is a prominent and important issue of public health, especially in pregnant women. The objective of this study is to describe the clinical characteristics; learn knowledge, attitudes, practice oral hygiene and assess the need for treatment of periodontal disease in pregnant women. Subjects and Methods: A cross-sectional study of 210 pregnant women who visited the Department of Obstetrics and Gynecology at the Hue University of Medicine and Pharmacy Hospital. Clinical examination and interview questions on knowledge, attitudes and practice of oral care for all subjects. Results: The incidence of gingivitis was 100%, with mild gingivitis of 4,3% and moderate gingivitis of 95.7%. There was a difference in incidence rates of gingivitis in the gestational period (p<0.001). The incidence of periodontitis is 17.6% and there is no difference in gestational age (p>0.05). The mean values of GI and BOP indices differed by gestation period (p<0.05) and PD, OHI-S, PlI have statistically significant relationship with gestation period (p>0.05). The incidence of periodontal disease is 80.5%; The percentage of pregnant women who abstain from brushing their teeth after birth is 61.4%. Prevalence of brushing once a day: 7.1%; Twice a day: 70.5% and 3 times daily: 22.4%; The mean values of GI, PD, BOP, OHI-S and PlI were inversely proportional to the number of brushing (p<0.001). The rate of dental hygiene is just 3.3%; The rate of oral hygiene, dental plaque and plaque removal was 94,3%; The proportion of subjects required for intensive treatment is 2.4%. Conclusion: Periodontal disease, especially for pregnant women, is high. It is necessary to educate the knowledge, attitudes and practice of proper oral hygiene and to better meet the demand for periodontal disease treatment for pregnant women. Key words: Periodontal disease, pregnant women, knowledge, attitude, practice for oral hygiene, treatment needs

Background: Tibial tubercle–trochlear groove (TT-TG) distance is often used as a measure of lateralization of the TT and is important for surgical planning. Purpose: To investigate if increased TT-TG distance measured on axial magnetic resonance images is due to lateralization of the TT or medialization of the TG. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 84 knees (28 normal [NK], 28 with trochlear dysplasia [TD], and 28 with patellar dislocation without TD [PD]) were examined. The medial border of the posterior cruciate ligament (PCL) was chosen as the central anatomic landmark. The distance from the TT to PCL (TT-PCL) was measured to examine the lateralization of the TT. The distance from the TG to the PCL (TG-PCL) was measured to examine the medialization of the TG. Between-group differences were investigated by use of 1-way analysis of variance. Results: The mean values for TT-TG distance were 8.7 ± 3.6 mm for NK, 12.1 ± 6.0 mm for PD, and 16.7 ± 4.3 mm in the TD group ( P < .01). The mean values for TT-PCL distance were 18.5 ± 3.6 mm for NK, 18.5 ± 4.5 mm for PD, and 21.2 ± 4.2 mm in the TD group ( P = .03). The mean values for TG-PCL distance were 9.6 ± 3.0 mm for NK, 7.1 ± 3.4 mm for PD, and 5.1 ± 3.3 mm in the dysplastic group ( P < .01). Conclusion: The present results indicate that increased TT-TG distance is due to medialization of the TG and not lateralization of the TT. Knees with TD had increased TT-TG distance compared with the knees of the control group and the knees with PD. The TT-PCL distance did not differ significantly between groups, whereas the TG-PCL distance declined with increased TT-TG.

Objective: The main objective of this study is to evaluate the availability of lateral antebrachial cutaneous nerve (LACN) autograft for acute or delayed repair of segmented digital nerve injuries. Patients and Methods: 13 digital nerve defects of 11 patients; treated with interposition of LACN graft that harvested from ipsilateral extremity were included in the study. Mean follow up period was 35, 7 months. The mean time from injury to grafting is 53, 3 days. The results of the mean 2PDT and SWMT values of injured /uninjured finger at the end of follow up period were evaluated with Paired T test. The correlation between the defect length and the difference of 2PDT, SWMT values between the uninjured and injured finger at the end of follow up period; were evaluated with Pearson - correlation analysis. Results: The mean value of our 2PDT and SWMT results are ~5,923, ~3, 52, respectively in which can be interpreted between the normal and diminished light touch. The defect length and difference percentage of SWMT values is positively and significantly correlated statistically. Mean length of interposed nerve grafts was 18.5 mm. The age of the patient and the mean values of 2PDT and SWMT with the difference % of 2PDT and % of SWMT are not statistically correlated. Conclusion: Based on results regarding sensory regaining at recipient side and negligible sensory deficit at harvesting side, we suggest that lateral antebrachial cutaneous nerve might be a valuable graft option for digital nerve defects.

AbstractObjective. Type 2 diabetes mellitus (T2DM) is characterized by a relative insulin deficiency or insulin resistance. It is also associated with a cluster of metabolic abnormalities, including hyper-tension and dyslipidemia. Although there are many studies that have studied the metabolic abnormalities in T2DM patients with metabolic syndrome (MetS), only few of them have assessed the metabolic abnormalities in their first-degree relatives (FDRs) who had MetS. The aim of this study is to compare the clinical and biochemical variables in T2DM subjects and their FDRs without diabetes in Benin City, Nigeria.Methods. This is a cross sectional case control study including 124 T2DM patients, 96 FDR of T2DM subjects, and 96 controls recruited using convenience sampling. Data were collected using a questionnaire-administered technique. Variables of interest that were assessed included anthropometric indices like waist circumference (WC), hip circumference (HC), waist:hip ratio (WHR), body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum lipid profile, fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), proteinuria, and microalbuminuria. The 1999 World Health Organization (WHO) criteria were used to make a diagnosis of metabolic syndrome. The Chi-square test was used for comparison of proportions. P-value of less than 0.05 was taken as statistically significant. The student t-test was used to compare means and test for significant differences in the anthropometric and the metabolic indices.Results. The prevalence of the MetS in T2DM persons was 87.1%, 16.7% in the FDR group, and 13.5% in the control group according to the WHO criteria. The mean value of HbA1c was significantly higher in T2DM subjects with MetS (p<0.05). The mean values of WC, FPG, total cholesterol, HDL cholesterol, and LDL cholesterol were higher in subjects with MetS in the T2DM group than in persons with MetS in the FDR group though not significant (p>0.05). The mean values of WHR, BMI, SBP, DBP, and triglyceride were higher in persons with the MetS in the FDR group than in persons with the MetS in the T2DM group. The difference in the BMI and SBP was significant (p<0.05).Conclusion. The prevalence of MetS in subjects with T2DM in Nigeria is very high. Though, all the biochemical and clinical indices were higher in T2DM subjects with MetS, the mean HbA1c, BMI, and SBP was significantly higher when compared to their FDR who also have MetS.

ABSTRACT: Crambe is a rapeseed with high oil content and can be used as a winter cover or as a source of raw material for the production of biodiesel, however espite the growing interest in the culture, research on the subject is still incipient, especially concerning the seed production and analysis technology. The purpose of this study is to evaluate the physiological quality of crambe seeds, 'FMS Brilhante' cultivar, by testing the pH of exudate. Five seed lots were submitted to the determination of water content and the tests of germination and vigor (first count, emergence and tetrazolium). In the conduction of pH exudate test, temperatures (25 and 30oC), and periods of seed imbibition in water (15, 30 and 45 minutes) were tested. The experiment was conducted in a completely randomized manner, with four replicates, and the mean values were compared by the Tukey test at 5% probability; Pearson correlation between the pH of the exudate and initial tests was also made. Testing the pH of exudate is promising for separating lots of crambe seeds and the following combinations of 25°C/30 minutes or 30°C/45 minutes can be used.
