Aim: This retrospective study investigated the survival rate and clinical performance of space maintainers fitted in 50 patients aged from 6-11years in the Department of Pediatric Dentistry at Selcuk University between 2016 and 2019. Methodology: Sixty-one subjects were included in the study. The clinical examination included performing the gingival index (GI) and the plaque index. The values of the indexes were determined and compared, and the failures of retainers were recorded and analyzed in terms of survival. Results: Follow-up loss occurred in 18% of 61 space maintainers. A total of 10% of the evaluated 50 space maintainers had failed due to breakage. By using the Kaplan–Meier method, the estimated mean survival time for space maintainers was 13 months. Lingual arches had the lowest mean survival time of 12 months. Band and loops and removable partial dentures had a similar probability of survival. A significant decrease was observed in the time-dependent evaluation of the means of plaque and gingival indexes; however, no significant difference was found between space maintainer types. Conclusion: The successful use of space maintainers for the premature loss of primary tooth space is achieved by regular follow-ups with the patient’s parents, patient cooperation, and proper space maintainers and choice of material.   How to cite this article: Özüdoğru S, Tosun G.

SUMMARY Purpose: This randomized clinical trial evaluated the influence of the occlusogingival distance (OGD) of noncarious cervical lesions (NCCLs) on the clinical performance of a regular bulk-fill resin composite and a regular nanofilled resin composite. Methods and Materials: A total of 140 restorations were randomly placed in 77 participants by one operator. NCCLs were divided into four groups (n=35) according to OGD (1.5 mm±10% or 3 mm±10%) and resin composites (Filtek Bulk Fill Posterior [B] or Filtek Z350 XT [C]) used: 1.5 mm-B, 1.5 mm-C, 3 mm-B, and 3 mm-C. A two-step self-etch adhesive (Clearfil SE Bond) was applied following manufacturer instructions in all restorative procedures. Restorations were polished 1 week after placement. Clinical evaluation was performed at baseline (7 days), 6 months, and 1 year by two calibrated examiners, according to the modified US Public Health Service criteria evaluating fractures/retention, marginal staining, marginal adaptation, recurrence of caries, anatomic form, postoperative sensitivity, and surface texture. The Kruskal-Wallis test was used for intergroup comparison in each follow-up; the Friedman analysis of variance, followed by the least significant difference test (multiple comparisons) was used for intragroup comparison between baseline and follow-up times (α=0.05). Results: Two restorations were lost at 12 months (1 for 1.5 mm-B and 1 for 3 mm-B). The retention rates at 12 months were 100% for 1.5 mm-C, 97% for 1.5 mm-B, 100% for 3 mm-C; and 97% for 3 mm-B, with no statistical difference among the groups (p=0.570). At 12 months, a statistically significant difference was found among the follow-up times for the same group (1.5 mm-B, 1.5 mm-C, and 3 mm-B) regarding the marginal staining criterion; moreover, the 3 mm-C group showed a significant difference from 6 months. No significant difference was found for the other parameters. Conclusion: Both resin composites showed acceptable clinical performance, and the OGD of NCCLs did not influence the clinical performance of resin composite restorations after 12 months.

Objective: This study investigated the clinical and prognostic characteristics of head and neck cancer in patients with esophagus cancer. Methods: Information on 124 patients with head and neck cancer with esophagus cancer was collected from head and neck and thoracic surgery departments between January 2007 and December 2016 in Zhejiang Cancer Hospital. The incidence of synchronous and metachronous cancer was described. The clinical characteristics and prognosis were also compared in synchronous and metachronous cancer. The number of hospitalization and different treatments were analyzed the affection on the survival time. Results: 32 cases were synchronous cancer and 72 cases were metachronous cancer. The rate of surgery and the number of hospitalization were significantly different in synchronous and metachronous cancer (χ2=4.661; P<.05). The 1-year, 3-year, and 5-year survival rates were 39.9%, 19.9%, and15.2%, respectively in patients with synchronous cancer and the mean survival time was 18.4±6.2 months. In contrast, the survival rates were 78.7%, 77.8%, and 59.1% respectively in metachronous cancer and the mean survival time was 122.2±17.2 months. There was a significant difference between the 2 groups (χ2=10.934; P=.001). The number of hospitalizations greater than or equal to 5 times were significantly different from those with less than 5 times (χ2=10.574; P=.001). There was no statistically significant difference in the improvement of OS by single operation, chemotherapy, and target treatment. The P value was only slightly less than .05 in the radiation therapy. Conclusions: Head and neck cancer in patients with esophagus cancer have a high survival rate through active combined-modality therapies, especially in metachronous carcinoma.

Abstract Background HE4 is expressed in most lung adenocarcinomas and in a significant number of squamous, small cell and large cell carcinomas of the lung, suggesting that it could be used as a diagnostic and/or prognostic factor to refine the standard pathologic analysis. Methodology Data was collected prospectively in the form of blood sample withdrawn from patients with NSCLC confirmed with pathology presented to bronchogenic clinic in Oncology department of Ain Shams University in pretreatment state & from healthy controls with matched age & sex. The Human HE4 (Epididymal Protein 4) was measured in serum samples using Enzyme linked immunosorbent assay [ELISA], the assay was performed using Human HE4 9Epididymal protein 4) ELISA kit, cat no: EH0365 (Fine Test, Wuhan Fine Biotech Co., China). Results 77 patients with NSCLC cases & 30 healthy controls were enrolled in the study. Serum HE4 showed to have to a diagnostic tendency were its value in NSCLC cases was from 42 to 130 pmol/l (median= 72pmol/l). but in controls its value was from 10 to 67 pmol/l (median = 35 pmol/l), which was highly statistically significant (P = 0.001). The cut off value of serum HE4 was 60 pmol/l with sensitivity 77% & specificity 96% (95% CI 0.9-1). Serum HE4 showed to be a poor prognostic marker to OS with statistically significant difference were those with pretreatment serum HE4&lt; 72 pmol/l mean survival time 17.6 months in comparison to the group with pretreatment serum HE4 &gt; 72pmol/l mean survival time 13.2 months (p = 0.02). Conclusion There is a negative correlation between Serum HE4 in NSCLC & overall survival, the highest the serum level the shortest the survival. This result can present serum HE4 as a novel prognostic & probably diagnostic marker for NSCLC.

Abstract Objective The purpose of this study was to evaluate the two year clinical performance of posterior composite restorations in endodontically treated premolars and molars using a hybrid composite (Filtek Z-250, 3M ESPE) and a total etch bonding system (Single Bond, 3M ESPE). Method and Materials Thirty-nine class II restorations in endodontically treated premolars (n=11) and molars (n=28) of 27 patients (14 female, 13 male, mean age 36.51) in 16 maxillar and 23 mandibular teeth were placed by one operator. Restorations were evaluated by two experienced investigators at baseline, 12 months, and 24 months according to the modified United States Public Health Service (USPHS) criteria that included retention, color match, marginal discoloration, secondary caries, anatomic form, marginal adaptation, and surface texture. All restorations were able to be evaluated at baseline, 12 months, and 24 months. Results Paired samples t-test showed only marginal discoloration showed a statistically significant difference (p<0.05) at the end of 24 months, and no other significant differences were observed for the other variables examined over the duration of the study. None of the restored teeth showed periapical pathology at the end of 24 months. Conclusion At two years, limited deterioration in marginal discoloration was detected. The clinical performance of posterior composite restorations in endodontically treated teeth using Filtek Z250 was found clinically acceptable after two years.

Help in detecting diabetes may come from an unlikely source like a dentist as an allied health team, as it is rightly said ‘oral cavity is the mirror of the body system’. They may diagnose undetected cases of diabetes and may refer to a physician for further evaluation and treatment. Research studies have found a link between periodontal (gum) disease and diabetes. Symptoms of the disease often appear in the mouth, while almost one-third of people with diabetes have severe periodontal disease. This is believed to be a result of the diabetic patient’s greater susceptibility to developing infections. Conversely, severe periodontal disease may increase the risk of developing diabetes, and may make it more difficult to manage blood sugar levels. However, studies have found that patients who receive treatment for periodontal disease may be able to control the condition with less insulin. Dentists often detect symptoms of diabetes during routine oral health examinations. Foamy saliva, unusually dry and irritated tissue, poor periodontal conditions inside the mouth are tell-tale signs of the condition. And, diabetic patients often lose more teeth compared to patients without the disease. Proper and effective management of patients with diabetes requires that the practice evaluate all aspects of patient interaction. Systems need to be customized so that all procedures and patient communication scripts are implemented consistently to meet the distinct needs of patients with diabetes. Hence based on above findings the present study was planned for clinical evaluation of the tooth loss in periodontal disease in diabetic patients. The present study was planned in Department of Public Health Dentistry, Buddha Institute of Dental Sciences, Patna ,Bihar for a period of six months from January 2019 to June 2019. Total 40 patients were evaluated during this period . Out of that 20 cases are of Diabetic patients were enrolled in first group and another second group consist of 20 control patients without any diseases. The data generated from the present study concludes that there is significant difference in teeth loss amongst diabetics and non-diabetics. People with diabetes should be aware about the periodontal complications associated with it and should go for regular dental visits. Therefore it is the need of the hour to educate the dentists, general physicians and specialists about the association of systemic diseases with oral health and vice versa as many of the systemic diseases may be prevented and improved by improving oral hygiene.

BACKGROUND Gingivitis is a non-painful, inflammatory condition that can be treated with home remedies. Left untreated gingivitis can lead to tooth loss. Periodic dental examinations are important for early diagnosis and treatment of gum diseases. In order to contain the spread of the corona virus, governments, including in Israel, have restricted movements of their citizens which has caused routine dental checkups to be postponed. OBJECTIVE This study aimed to examine the ability of an mHealth app- iGAM to reduce gingivitis. METHODS A prospective observational cohort study was performed, 160 unpaid participants were divided into 2 equal groups and downloaded the iGAM app. Group 1 photographed their gums weekly for eight weeks. Group 2 photographed their gums at the time of recruitment and 8 weeks later. After photo submission, the participants received the message "It is recommended to read the information contained within the app regarding maintaining oral hygiene habits". A single blinded researcher examined the images and scored them according to the Modified Gingival Index (MGI). RESULTS The average age of group 1 was 26.77 (S.D. ± 7.43), and 28.53 (S.D. ± 10.44) for group 2. The majority were male (74.7% in group 1 vs. 66.7% in group 2), most participants described themselves as "secular", most were "single", non-smokers (74.7% vs. 78.4%) and did not take medications (85.3% vs. 78.4%). 126 subjects completed the study. A statistically significant difference (P <.001) was found in the dependent variable (MGI) in a linearly negative manner. As time passed, the gum condition improved, there were significantly lower gingivitis scores in group 1 (M = 1.16, S.D. ± 1.18) compared to group 2 (M = 2.16, S.D. ± 1.49), after eight weeks. Those with more recent dental visits had a lower MGI (p = .037). No association was found between knowledge and behavior, most participants were familiar with the recommendations for maintaining oral health, yet they only performed some. CONCLUSIONS A dental selfie taken once a week using an mHealth app (iGAM) reduced the signs of gingivitis and promoted oral health. During the current pandemic where social distancing recommendations may be causing people to avoid dental clinics, this app can remotely promote gum health. CLINICALTRIAL The protocol was approved by Hadassah research ethics committee (IRB, 0212-18-HMO)

Abstract Objectives Pancreatic cancers in most patients in Ecuador are diagnosed at an advanced stage of the disease, which is associated with lower survival. To determine the characteristics and global survival of pancreatic cancer patients in a social security hospital in Ecuador between 2007 and 2017. Methods A retrospective cohort study and a survival analysis were performed using all the available data in the electronic clinical records of patients with a diagnosis of pancreatic cancer in a Hospital of Specialties of Quito-Ecuador between 2007 and 2017. The included patients were those coded according to the ICD 10 between C25.0 and C25.9. Our univariate analysis calculated frequencies, measures of central tendency and dispersion. Through the Kaplan-Meier method we estimated the median time of survival and analyzed the difference in survival time among the different categories of our included variables. These differences were shown through the log rank test. Results A total of 357 patients diagnosed with pancreatic cancer between 2007 and 2017 were included in the study. More than two-thirds (69.9%) of the patients were diagnosed in late stages of the disease. The median survival time for all patients was of 4 months (P25: 2, P75: 8). Conclusions The statistically significant difference of survival time between types of treatment is the most relevant finding in this study, when comparing to all other types of treatments.

This study evaluated the one-year clinical performance of a one-step, self-etch adhesive (Optibond All-in-One, Kerr, CA, USA) combined with a composite (Herculite XRV Ultra, Kerr Hawe, CA, USA) to restore NCCLs with or without prior acid etching. Restorations performed by the same practitioner were evaluated at baseline and after 3, 6, and 12 months using modified USPHS criteria. At 6 months, the recall rate was 100%. The retention rate was 84.2% for restorations with prior acid etching, but statistically significant differences were observed between baseline and 6 months. Without acid etching, the retention rate was 77%, and no statistically significant difference was noted between 3 and 6 months. Marginal integrity (93.7% with and 87.7% without acid etching) and discoloration (95.3% with and 92.9% without acid etching) were scored as Alpha or Bravo, with better results after acid etching. After one year, the recall rate was 58.06%. Loss of pulp vitality, postoperative sensitivity, or secondary caries were not observed. After one year retention rate was of 90.6% and 76.9% with and without acid conditioning. Optibond All-in-One performs at a satisfactory clinical performance level for restoration of NCCLs after 12 months especially after acid etching.
