Peri-implantitis management could be performed either with a surgical or non-surgical approach to the implant surfaces. Various treatment options have been proposed in the literature, such as antiseptic and antibiotic therapies, chemical agents, curettes, ultrasonic, air abrasive, rotary titanium brushes and laser treatments; in particular, photodynamic therapy combined with hydrogen peroxide (OHLLT) has proved to be efficient in the removal of bacterial biofilm from implant surfaces. The aim of our study is to compare OHLLT performed with a surgical approach to a non-surgical approach. We selected a cluster of 227 implants affected by peri-implantitis: 139 implants were treated with a non-surgical approach and 88 implants with a surgical approach. Bone loss pre-operative and post-operative (with a follow-up of five years) have been registered. The collected data were entered on the Statistical Package for Social Sciences (SPSS) version 11.5. The results indicate a statistically significant difference between the two groups, with a mean bone loss after treatment of 2.3 mm for OHLLT with a surgical approach and 3.8 mm for OHLLT with a non-surgical approach; according to the Kolmogorov–Smirnov test, the overall data followed a normal distribution (value of the Kolmogorov–Smirnov test statistic = 0.0891; p = 0.35794). Thus, a surgical approach in the case of peri-implantitis seems to be more effective, probably due to the possibility of a deeper sanitization of implant surfaces, hardly reachable with only non-surgical approach.

In peri-implantitis, treatment lasers are effectively used to enhance implant surfaces’ decontamination of bacteria. The type of lasers commonly used and tested in dentistry are Nd:YAG, Er:YAG and diodes. The Er:YAG laser is considered to be effective in removing biofilm from implant surfaces. Photodynamic therapy (PDT), realized with low-level laser therapy (LLLT) and a photosensitizer, seems to have limited efficacy in peri-implantitis management, while diode lasers used with high frequency and power (Wiser, Doctor Smile), performed with hydrogen peroxide 10 vol. 3% (OHLLT), seems to lead to a deep sanitization of implant surfaces, without any thermal effect. The aim of our retrospective controlled study is to compare an oxygen high-level laser therapy (OHLLT) protocol with OHLLT with an Er:YAG laser (Pluser, Doctor Smile) in order to maximize bacterial removal and to evaluate if an Er:YAG laser could improve hard tissue regeneration with respect to OHLLT alone. Two hundred and ten implants affected by peri-implantitis were divided into two groups: 88 implants were treated with OHLLT alone (control group) while 122 underwent OHLLT and Er:YAG treatment (test group). Mean bone loss before (T0) and after treatment (T1) (with a follow-up of 5 years) was registered for all implants. The collected data were analyzed with the Statistical Package for Social Sciences (SPSS) version 11.5. No statistically significant differences were found. In the OHLLT group, we noticed a mean bone loss after treatment of 2.1 mm in the upper arch and 2.4 mm in the mandible. In the OHLLT + Er:YAG group, the results indicate a mean bone loss of 2.0 mm in the upper arch and 2.5 mm in the mandible. Both groups showed a mean bone loss after treatment of 2.3 mm. According to the Kolmogorov–Smirnov test, overall, data followed a normal distribution (value of the K-S test statistic = 0.0912; p = 0.36112). OHLLT plays a central role in enhancing clinical results in peri-implantitis treatment, leading to an effective bacterial decontamination. Our results showed no statistically significant differences between OHLLT and OHLLT + Er:YAG laser; thus, the potential advantageous role of Er:YAG has been downgraded with the analysis of our study.

The aim of this study is to investigate the nutritional approaches of student athletes studying at the university during the coronavirus outbreak period. Participants consisted of students studying and doing sports at the University. 446 students, 246 males and 200 females, participated in the study. Besides the personal form, students were filled the questionnaire testing questionnaire. Students voluntarily participated. The surveys were done on social media. Nutritional habits questionnaire consists of 12 questions. In the preparation of the survey questions, the questions proved validity of the researches which have been done on the subject before have been used. SPSS 23.00 package program was used in statistical analyses. Kolmogorov-Smirnov test was performed to test whether the data was normally distributed and it was determined that the data showed normal distribution. Independent t-test, paired t-test, unidirectional variance analysis and LSD tests were used in statistical operations. There was no significant difference in students' nutrition approaches by gender, both in the pre-outbreak period and in the outbreak period points (p> 0.05). Nutrition scores were significantly increased during the outbreak period (p <0.001). A significant difference was found between the students who felt bad before the epidemic and those who felt well before the epidemic and their nutritional scores according to the levels they felt (p <0.05). A significant difference was found between the pre-outbreak period and post-epidemic nutrition scores of the sports faculty students (p <0.05). During the coronavirus epidemic, university student athletes have either increased their nutritional opportunities or have changed their eating habits positively to keep their immune systems strong or both. The fact that sports faculty students have better nutrition compared to other faculty students can be attributed to their taking courses in nutrition, health and similar. It is recommended to give lectures or seminars on nutrition to athlete students. Keywords: Student, Nutrition, Sports Nutrition, Nutritional Approach, Covid-19

Objective To determine whether statistical differences occur in total cost, length of stay, ICU days, and surgical complications, depending on the volume of laryngectomy procedures performed. Methods Secondary laryngectomy data from 108 hospitals participating in the University Health System Consortium was examined. All laryngectomy surgical cases occurring from July 1, 2001, through June 30, 2005, with an ICD-9 code of 30.3 or 30.4 were analyzed (N=4,551). The cases were divided into 3 categories based on the number of surgical laryngectomy cases performed by hospital. Those volume categories were high, as defined by organizations with 100–233 cases (n=1712); medium, between 60–99 cases (n=1353); and low, between 4–59 cases (n=1458). 4 dependent variables were examined including total cost, length of stay, ICU days, and complications. Results The 4 dependent variables were analyzed for normality by performing a Kolmogorov-Smirnov test. All 4 variables were non-normally distributed. A Kruskal-Wallis test was then performed on each variable to determine if a statistically significant difference appeared between the 3 volume categories. Each variable was found to have statistical significant differences between the groups, with the high volume hospitals having the lowest cost, shortest length of stay, shortest ICU days, and smallest complication rate. Conclusions This study showed that hospitals with higher surgeon volume for total laryngectomies had reduced total cost, length of stay, number of ICU days, and complication rate for their patients.

Introduction: Taro village has a higher risk of gathering the people since it is one of the most popular tourism sectors in Bali hence increasing the potential to spread coronavirus disease 2019 (COVID-19). The level of knowledge plays an important role in determining whether the society is ready to implement the health protocols or not. This community service aims to evaluate the level of knowledge regarding COVID-19 health protocols in the tourism sector in the Taro village. Method: This research was conducted using a quasi-experimental one-group pretest-posttest design in Taro village, Bali. Respondents filled out the questionnaire before and after counseling. The questionnaire consisted of 10 items of knowledge. The participants were Taro’s residents who met inclusion and exclusion criteria. A total of 31 respondents were taken. The data were tested for normality with the Kolmogorov-Smirnov test and analyzed with paired T-test using the IBM SPSS statistics version 25. Significance was determined at a 5% level (P-value ≤0.05). Results: A total of 31 valid filled-questionnaires were collected. In general, Taro’s residents’ knowledge regarding COVID-19 health protocol in the tourism sector was sufficient, but some topics are still insufficient. The mean score before counseling was 79,03 ± 1,340 while the mean score after counseling was 86,13 ± 1,366. There was a significant difference (p<0,05) on level of knowledge (p=0,000) before and after counseling. Conclusion: There was a significant difference in the level of knowledge of Taro village’s residents toward COVID-19 health protocols in the tourism sector before and after counseling.

Latar Belakang: Upaya peningkatan derajat kesehatan pada sektor lingkungan salah satunya dengan pengadaan sarana lingkungan fisik yang sehat seperti jamban keluarga. Berdasarkan data Laporan Kemajuan Akses Sanitasi Kumulatif Nasional Tahun 2019, penduduk Jawa Timur yang masih menumpang ke jamban sehat sebanyak 879.969 Kepala Keluarga dan yang berperilaku Open Deficiation (OD) sebanyak 969.663 KK.Tujuan: Menganalisis perbedaan faktor enabling terhadap praktik buang air besar antara desa belum ODF dengan desa ODF.Metode: Jenis penelitian observasional analitik kuantitatif dan kualitatif dengan desain penelitian Cross Sectional. Dianalisis secara univariate menggunakan uji One Sample Kolmogorov-Smirnov test dan bivariat menggunakan uji Mann-Whitney U test”. Dari uji ini diperoleh kemungkinan hasil uji yaitu signifikan atau bermakna α = 0,05 maka terdapat perbedaan yang bermakna antara variable yang diuji. Hipotesa diterima apabila p value ≤ 0,05.Hasil: Uji statistik Mann Whitney U test menyatakan adanya perbedaan pada praktik buang air besar antara desa belum ODF (Kelurahan Jagir) dan desa ODF (Kelurahan Ketintang) dimana pada kepemilikan lahan pada Kelurahan Jagir masyarakat tidak memiliki lahan sendiri dan lahan yang ditempati merupakan milik PT. KAI yang berpengaruh pada ketersediaan jamban sehat, sekalipun memiliki jamban tetapi tidak dilengkapi dengan septic tank, sedangkan pada Kelurahan Ketintang rata-rata masyarakat memiliki lahan sendiri, sehingga mempermudah masyarakat memiliki jamban yang dilengkapi dengan septic tank. Hal ini dikarenakan nilai p-value = 0,000 < dari α (0,05), dimana jika p-value < α, maka H0 ditolak dan Ha diterima.Kesimpulan: Lahan yang ditempati  masyarakat Jagir bukan milik sendiri sehingga mempersulit warga untuk membangun jamban sehat, serta jamban yang ada tidak memenuhi persyaratan jamban sehat, sedangkan masyarakat Ketintang yang rata-rata tinggal di dekat sungai tetapi telah menerapkan praktik buang air besar yang benar dengan menggunakan jamban sehat.AbstractBackground: One of the efforts to improve health status in the environmental sector is the provision of a healthy physical environment such as family toilet. Based on data from the 2019 National Cumulative Access to Sanitation Progress Report, the population of East Java who still uses healthy latrines is 879,969 households and those who have Open Deficiation (OD) behavior are 969,663 families. Objective: Intervention of possible factors needs to be done because these factors are supporting/enabling factors, where if we do a certain intervention it will be difficult if the facilities and infrastructure are not available/ not supported. Methods: This type of research is observational analytic quantitative and qualitative whith a cross sectional research design. The data analysis technique was univariate using the One Sample Kolmogorov-Smirnov test and bivariate analysis using the Mann-Whitney U test. From this test, it is obtained that the test results are signicant or significant α = 0.05, so there is a significant difference between the tested variables. The hypothesis is accepted if the p value is ≤ 0.05. Results: The statistical  test of the Mann Whitney U test states that there is a differences in the practice of defecating between Kelurahan Jagir and Kelurahan Ketintang where in land ownership in Kelurahan Jagir, the community does not own their own land and the land occupied is owned by PT.KAI has an effect on the availability of healthy latrines, even though it has a latrine but is not equipped with a septic tank, while in Ketintang Village the average person has their own land, making it easier for the community to have a toilet equipped with a septic tank. Conclusion: The land occupied by the Jagir community is not their own, making it difficult for residents to build healthy latrines, and the existing latrines do not meet the requirements for healthy latrines, while the Ketintang community who mostly live near the river but have implemented the correct practice of defecating using healthy latrines.

Abstract Objective SARS-CoV-2 can be carried by aerosols and droplets produced during dental procedures, particularly by the use of high-speed handpieces, air-water syringes, and ultrasonic scalers. High-volume evacuators (HVEs) and extraoral vacuum aspirators (EOVAs) reduce such particles. However, there is limited data on their efficacy. This study aimed to determine the efficacy of HVE and EOVA in reducing aerosols and droplets during ultrasonic scaling procedures. Materials and Methods Three ultrasonic scaling simulations were conducted on mannequins: 1. saliva ejector (SE) was used alone (control); 2. SE was used in combination with HVE; and 3. SE was used in combination with HVE and EOVA. Paper filters were placed on the operator's and assistant's face shields and bodies, and the contamination of aerosols and droplets was measured by counting blue spots on the paper filters. Statistical Analysis All data were analyzed for normality using the Kolmogorov–Smirnov test. The differences between each method were analyzed using a two-way ANOVA, followed by a posthoc test. The differences were considered statistically significant when p < 0.05 Result Using HVE and EOVA reduced aerosols and droplets better than using SE alone or SE and HVE: the posthoc test for contamination revealed a significant difference (p < 0.01). The assistant was subjected to greater contamination than the operator during all three ultrasonic scaling procedures. Conclusion The usage of HVE and EOVA significantly reduced aerosols and droplets compared with using SE solely. Using these techniques together could prevent the transmission of airborne disease during dental cleanings, especially COVID-19. Further studies of aerosol-reducing devices are still needed to ensure the safety of dental workers and patients.
