<p><strong>Background:</strong> Clinicians are continually challenged to improve the standard of treatment. Careful measurements and designs, based on knowledge of tooth loss patterns and biomechanical principles, will determine the overall quality of removable prostheses.</p><p><strong>Objectives:</strong> This study maps the pattern of tooth loss in a sample of patients and the most efficient designs employed for their cobalt-chrome removable prosthesis.</p><p><strong>Material and Methods:</strong> Data was collected from gypsum casts, metal castings, and prescriptions sent to dental technicians. The sample included both men (44) and women (109). Information was obtained on their Kennedy classification, number of missing teeth in the maxilla and the mandible, the type of major connector fitted, and when additional indirect retainers with clasps were incorporated into the frame. The significance of the association between pairs of these categorical variables was tested by a Chi Square test.</p><p><strong>Results:</strong> Patients with maxilla loss (82%) had mostly (54%) 6 to 10 missing teeth and were assessed principally (78%) as exhibiting Kennedy Class II or III patterns. Most (77%) of those missing teeth in their mandible (66%) were assessed as either Class I or Class II. The Anterior-Posterior (70%) in the maxilla and the Lingual Bar (74%) in the mandible were the most common fitted connectors. Indirect retainers were used for patients with maxilla (78%) or mandible (96%) tooth loss to provide extra stability.</p><p><strong>Conclusion:</strong> Additional components incorporated in the Cobalt-Chrome frame increased the biomechanical efficiency of the appliance by reducing destructive forces, caused by the torque on the abutment teeth.</p>

The effect of preventive oral habits is largely unexplored in older individuals. The purpose of this study was to evaluate the associations between home use of flossing and prevalence of periodontal disease and caries in older adults. Five-year incident tooth loss was also evaluated. Data on 686 individuals ≥65 y-old from the Piedmont 65+ Dental Study were examined including: 1) interproximal clinical attachment level (iCAL), 2) interproximal probing depth (iPD), 3) numbers of caries, and 4) missing teeth. Flossing behavior was evaluated according to the Periodontal Profile Class (PPC) system. Five-year follow-up data ( n = 375) was evaluated for incident tooth loss. Dichotomous and categorical variables were analyzed using Pearson chi-square tests as well as covariate-adjusted Cochran-Mantel-Haenszel tests. Multiple linear regression compared clinical parameters based on flossing behavior. Elderly flossers had lower (mean, SE) %iCAL≥3 mm (38.2, 2.38 vs. 48.8, 1.56) and %iPD≥4 mm (8.70, 1.41 vs. 14.4, 0.93) compared to nonflossers ( P ≤ 0.005). Flossers showed less coronal caries compared to nonflossers ( P = 0.02). Baseline number of missing teeth (mean, SE) was 11.5 (0.35) in nonflossers compared to 8.6 (0.53) in flossers ( P < 0.0001). Regular dental visitors had lower oral disease levels compared to episodic dental users. The majority of flossers classified into PPC-Stage I (health) whereas nonflossers classified as PPC-Stages V, VI, and VII (disease). At the 5-y follow-up visit, the average tooth loss for flossers was ~1 tooth compared to ~4 teeth lost for nonflossers ( P < 0.0001). Among all teeth, molars showed the highest benefit (>40%) for flossing behavior ( P = 0.0005). In conclusion, the extent of oral disease for older individuals was significantly less in flossers than in nonflossers. Flossers showed less periodontal disease, fewer dental caries, and loss of fewer teeth over a 5-y period. These findings further support flossing as an important oral hygiene behavior to prevent oral disease progression in older adults.

Tooth loss is a common dental problem. Impairment of oral functions and masticatory efficiency is a result of tooth loss. The negative effects of tooth loss can be managed by the fixed and removable prosthesis. This study was conducted to determine the influence of gender in selecting prosthesis. This study was a retrospective observational study conducted in a university hospital in Chennai. Data collection was done with the help of the electronic dental record of the university- Dental information archiving software (DIAS). It records all patients data from initial visit to last visit chronologically. This was followed by Excel tabulation. Data was analysed using SPSS Software. The association of study variables was calculated using the Chi-Square test. Within the limits of the study, female patients were willing for replacement of teeth than male patients (55%). There was a significant difference in choosing the type of prosthetic treatment. It was seen that fixed partial denture was chosen over removable prosthesis (59.8%).

Individual perceptions towards denture wear’s are different from one to another, which are affected by number andlocation of missing teeth, age, sex, functional factors, esthetic, cultural factors, socioeconomy and education. Thepurpose of this study is to analyze the perceptions towards denture replacement among a rural community whoexperienced tooth loss based on age groups, sex and education in Desa Ujung Rambung Kecamatan Pantai CerminKabupaten Serdang Bedagai in February 2010. This study was an analytical observatory study. Samples are 200subjects who lost at least one tooth, excluding third molar. Chi-square test shows no significant difference betweenperceptions of appearance, mastication and speech and age groups, no significant difference between perceptions ofappearance, mastication and speech and sex, and no significant difference between perceptions of mastication andspeech and education (p>0,05), but shows statistically significant difference between perception of appearance andeducation (p=0,004). It can be concluded that the overall perceptions of the rural community is poor.

Abstract Background Neurocysticercosis is a Neglected Tropical Disease and an important public health issue. Our goal was to collect and analyze data regarding clinically significant gender differences among our Neurocysticercosis patients. Methods A retrospective chart search with ICD 9/ ICD 10 diagnostic code for Neurocysticercosis and neuroimaging suggestive of Neurocysticercosis was performed for clinical encounters in the hospital or affiliated clinics between years 2013–2018. After a careful chart review, patients who were clinically diagnosed with Neurocysticercosis were included in the study. T-test was used to compare means of continuous variables and chi-square test to compare proportions of categorical variables. Results Among 90 total patients included, male (49.4%) and female (50.6%) distribution were nearly identical. The mean age in females was found to be higher than males (52.5 vs 42.0, P &lt; 0.0001). Almost an equal number of males and females presented with either seizures (63.6% vs 57.8%, P= 0.85), headaches (25.0% vs 28.9%, p= 0.85), or other symptoms (11.4% vs 13.3%, p= 0.85). Males had more generalized seizures compared to females (60% vs 38%, P= 0.37), although this result was not statistically significant. Females were more likely to present with &gt; 1 lesion (82.2% vs 56.8%, P= 0.01). Males were more likely to have cystic lesions (64.7% vs 27.9%, P &lt; 0.001) compared to females who had more calcified lesions on presentation (65.1% vs 20.6%, P &lt; 0.001). Male patients were more likely to have contrast enhancement or edema surrounding the lesions (61.4% vs 33.3%, P= 0.01) and were more likely to require treatment with Albendazole/Praziquantel (75.8% vs 31.7%, P &lt; 0.001). Conclusion Although previously reported data is limited, there is a suggestion that there are gender differences in host immune response and that inflammation surrounding parenchymal lesions is more intense in females. This study suggests that men either present early in the disease phase or have different immune responses than women and require anti-parasitic therapy more frequently. More research in this aspect is needed. Disclosures All Authors: No reported disclosures

Background: In 2013, the NIH Stroke Trials Network (StrokeNET) was established to maximize efficiencies in stroke clinical trials. Successful recruitment in future trials was required for participating sites. A high volume of cases treated is a surrogate for the potential to recruit. Among Medicare-eligible acute ischemic stroke (AIS) cases, we estimated the IV rt-PA and endovascular embolectomy treatment rates at StrokeNET Regional Coordinating Centers and their partner hospitals compared with non-StrokeNET hospitals in the United States (US). Methods: We used demographics and IV rt-PA and embolectomy rates in the 2013 Medicare Provider and Analysis Review (MEDPAR) dataset. ICD-9 codes 433.xx, 434.xx and 436 identified AIS cases. ICD-9 code 99.10 defined rt-PA treatment and ICD-9 code 39.74 defined embolectomy. Demographics and treatment rates at StrokeNET and non-StrokeNET sites were compared using t-test for proportions and Chi-square test for categorical variables as appropriate. Results: Of 386,157 AIS primary diagnosis discharges, 5.1% received IV rt-PA and 0.8% had embolectomy (Table). By June 6, 2014, StrokeNET comprised 247 acute care hospitals that discharged 48,946 (13%) out of 386,157 AIS cases. rt-PA (7.4% vs 4.8%) and embolectomy (1.9% vs 0.6%) treatment rates were higher at StrokeNET hospitals. In 2013, 36% of StrokeNET hospitals treated more than 20 AIS cases with rt-PA or embolectomy compared with 6% of non-StrokeNET hospitals (P<0.0001).Conclusions StrokeNET hospitals treat more AIS cases with acute reperfusion therapies. Thus, StrokeNET could successfully recruit in acute reperfusion clinical trials depending on study size, capture of eligible patients and the number of competing trials. We likely underestimated treatment rates due to not accounting for drip-and-ship and non-Medicare cases. To further enhance enrollments in large acute reperfusion phase 3 trials, partnership with high volume non-StrokeNET hospitals may be warranted.

SUMMARY Bulk-fill composites have been introduced to facilitate the placement of deep direct resin composite restorations. This study aimed at analyzing the cervical marginal integrity of bulk-fill vs incremental and open-sandwich class II resin composite restorations after thermomechanical cycling using replica scanning electron microscopy (SEM) and ranking according to the World Dental Federation (FDI) criteria. Box-only class II cavities were prepared in 91 maxillary premolars with the gingival margin placed 1 mm above and below the cemento-enamel junction. Eighty-four premolars were divided into self-etch and total-etch groups, then subdivided into six restorative subgroups (n=7): 1-Tetric Ceram HB (TC) was used incrementally and in the open-sandwich technique with 2-Tetric EvoFlow (EF) and 3-Smart Dentin Replacement (SD). Bulk-fill restoratives were 4-SonicFill (SF), 5-Tetric N-Ceram Bulk Fill (TN), and 6-Tetric EvoCeram Bulk Fill (TE). In subgroups 1-5, Tetric N-Bond self-etch and Tetric N-Bond total-etch adhesives were used, whereas in subgroup 6, AdheSE self-etch and ExciTE F total etch were used. One more group (n=7) was restored with Filtek P90 Low Shrink Posterior Restorative (P9) only in combination with its self-etch P90 System Adhesive. Materials were manipulated and light cured (20 seconds, 1600 mW/cm2), and restorations were artificially aged by thermo-occlusal load cycling. Polyvinyl-siloxane impressions were taken and poured with epoxy resin. Resin replicas were examined by SEM (200×) for marginal sealing, and percentages of perfect margins were analyzed. Moreover, samples were examined using loupes (3.5×) and explorers and categorized according to the FDI criteria. Results were statistically analyzed (SEM by Kruskal-Wallis test and FDI by chi-square test) without significant differences in either the replica SEM groups (p=0.848) or the FDI criteria groups (p&gt;0.05). The best SEM results at the enamel margin were in TC+EF/total-etch and SF/total-etch and at the cementum margins were in SF/total-etch and TE/self-etch, while the worst were in TC/self-etch at both margins. According to FDI criteria, the best was TE/total-etch at the enamel margin, and the poorest was P9/self-etch at the cementum margin. Groups did not differ significantly, and there was a strong correlation in results between replica SEM and FDI ranking.

Abstract Background: Undernutrition is an inadequate supply of energy and nutrients. Periodontal diseases (PDs) defined as a broad form of chronic inflammatory diseases of the gingiva, bone and ligaments supporting the teeth. This study aimed to reveal the effect of undernutrition, using body mass index (BMI) and serum albumin level (Alb) on PDs and other risk factors as age, smoking and khat chewing. Methods: This was a cross-sectional study conducted at the faculty of dentistry, Sana’a University. Of 1920 patients attended to clinics, only 229 matched the study criteria. Oral examination was performed to assess the periodontal clinical parameters measurements. BMI and Alb was measured. Statistical analysis was used to present the association between categorical variables was assessed using Chi square test and Fisher-Exact test. ANOVA was used to assess the differences in the mean values of the quantitative outcomes. Chi square test was used to evaluate the association between BMI and age, gender, occupation, education level, smoking, khat chewing as well as BMI with PDs. Results: Most of participants (58.5%) were males and most of the study sample (91.3%) was at the age group of (18-35). Among all subjects, (81.2%) of cases were diagnosed with gingivitis. (60.7%) of study participants were mildly undernourished according to BMI. (93%) of participants showed normal Alb level. Regarding to habits, only (18.2%) of patients were smokers and more than half of participants (59.4%) were khat chewers. Conclusion: There was a relationship between PDs and undernutrition which was obviously seen between gingivitis and mild undernutrition.

Abstract Background Non-prescription antibiotic use at community is a main driver of antimicrobial resistance. Cough is a common condition and prevalent in all communities, including China. This study aims to investigate the non-prescription antibiotic use for cough in China and explore to which extent antibiotic use knowledge was correctly instructed in communities.Methods A probability-proportionate-to-size (PPS) sampling method was adopted to survey from all 14 communities in Yiwu city, China. All participants were investigated by face-to-face interview on Portable Android Devices (PADs). The continuous variables were presented by mean and standard deviation (SD) or medium and inter-quartile range (IQR). The categorical variables were presented using percentage or constituent ratio. Chi-square test for univariate analysis and logistic regression for multivariate analysis were conducted to assess the odds ratios (ORs) and 95% confidence intervals (CIs), respectively.Results A total of 3034 respondents across the 14 communities and the 50 natural villages/streets completed all key items of the questionnaire. Of 2400 (79.10%) respondents stated that they experienced cough in the past 12 months with the medium age of 36.5 (IQR: 26-49) and 12.21% (293/2400) respondents had the non-prescription antibiotic use behavior. Among those 293 respondents, the proportion of non-prescription antibiotic use for cough peaked at around 16% among people aged 30-39 years old. The major sources of antibiotics were pharmacy (77.70%) and/or family storage (43.92%). As for antibiotic knowledge in 3034 participants, 61.8% participants had minimal knowledge on broad-spectrum antibiotic and 53.76% were not familiar about the effects of joint use.Conclusions Non-prescription antibiotics use for cough is prevalent in the community, especially among people in their thirties. Strengthened drug purchase regulation and well-trained professional pharmacists would be promising alternatives to ameliorate AMR. Moreover, penetrating antibiotics knowledge to common citizens and is an urgent task to alleviate antimicrobial resistance. Therefore, proactive policies and regulations should be made to improve current situations.

This study aims to assess the risk of severe forms of COVID-19, based on clinical, laboratory, and imaging markers in patients initially admitted to the ward. This is a retrospective observational study, with data from electronic medical records of inpatients, with laboratory confirmation of COVID-19, between March and September 2020, in a hospital from Juiz de Fora-MG, Brazil. Participants (n = 74) were separated into two groups by clinical evolution: those who remained in the ward and those who progressed to the ICU. Mann–Whitney U test was taken for continuous variables and the chi-square test or Fisher’s exact test for categorical variables. Comparing the proposed groups, lower values of lymphocytes ( p  = <0.001) and increases in serum creatinine ( p  = 0.009), LDH ( p  = 0.057), troponin ( p  = 0.018), IL-6 ( p  = 0.053), complement C4 ( p  = 0.040), and CRP ( p  = 0.053) showed significant differences or statistical tendency for clinical deterioration. The average age of the groups was 47.9 ± 16.5 and 66.5 ± 7.3 years ( p  = 0.001). Hypertension ( p  = 0.064), heart disease ( p  = 0.048), and COPD ( p  = 0.039) were more linked to ICU admission, as well as the presence of tachypnea on admission ( p  = 0.051). Ground-glass involvement >25% of the lung parenchyma or pleural effusion on chest CT showed association with evolution to ICU ( p  = 0.027), as well as bilateral opacifications ( p  = 0.030) when compared to unilateral ones. Laboratory, clinical, and imaging markers may have significant relation with worse outcomes and the need for intensive treatment, being helpful as predictive factors.
