Propolis is proposed to possess antibacterial and anti-inflammatory properties, which can be used in endodontic applications. However, evidence on its efficacy in comparison to chlorhexidine against Enterococcus faecalis (E. faecalis) is controversial. The aim of the current study was to compare the antibacterial efficacy of Propolis and chlorhexidine as an intracanal medicament against E. faecalis in extracted human permanent teeth. The focused question was, “Does Propolis show better antibacterial efficacy than Chlorhexidine (CHX) as an intracanal medicament against E. faecalis in extracted human permanent teeth?”. Databases including PubMed/Medline, Scopus, EMBASE, ISI-Web of Science were searched from 1990 to August 2020 using different combinations of the following keywords: “Propolis”, “Intracanal medicament”, “E. faecalis”, “Antibacterial activity” and “Chlorhexidine”. Ten studies fulfilling inclusion criteria were considered for qualitative analysis, followed by quantitative analysis of eight studies. Heterogeneity was calculated for colony forming units (CFU) of E. Faecalis using the Chi-square test and I2 statistics. Forest plots were computed reporting standard mean difference (SMD) of outcomes and 95% confidence intervals. The overall mean difference for CFU of E. faecalis showed a statistically significant difference between the antibacterial efficacy of Propolis and CHX (SMD = 3.20 [1.70, 4.69] Z = 4.20; p < 0.001). CHX showed superior antibacterial efficacy against E. faecalis compared to Propolis.

To compare the success of perceived pulpal anesthesia between groups using nitrous oxide/oxygen (N2O/O2) and oxygen (O2) in children premedicated with ibuprofen with symptomatic irreversible pulpitis permanent teeth. Thirty-three children (mean age 10.4 ± 1.9 years) with 33 symptomatic irreversible pulpitis permanent teeth were included in this preliminary study. All children were premedicated with ibuprofen and randomly assigned to receive either N2O/O2 (17 participants) or O2 (16 participants). Four percent articaine with epinephrine 1:100,000 was administered, and vital pulp therapy was performed. Children used the Wong-Baker FACES Pain Rating Scale (WBFPS) to report their pain at baseline as well as during carious dentin removal, pulpal exposure, and pulpal tissue removal steps. The success was determined when the reported WBFPS score was ≤4. The chi-square test was used to compare the success between both groups. The success of pulpal anesthesia was 71% (12/17) and 19% (3/16) in the N2O/O2 and O2 groups, respectively. The success in the N2O/O2 group was 52% higher than that in the O2 group (confidence interval = 22.9% to 80.7%; significant difference p = .003). From the result of this preliminary study, N2O/O2 significantly increased the success of perceived pulpal anesthesia in children premedicated with ibuprofen with symptomatic irreversible pulpitis permanent teeth. However, further study with a larger sample is required to confirm this result.

Background: Contact areas in primary teeth are known to be broader, flatter and situated farther gingivally than permanent teeth. The purpose of this study was to assess the prevalence of OXIS contact areas between primary molars using die models of children from two different ethnic populations. The research question of the present study is “What is the prevalence OXIS contact areas of primary molars in the populations studied?”. Methods: A cross-sectional study was planned in a representative sample of 200 caries-free contact areas among children aged 3-6 years in two centers, Ajman and Puducherry. Data collection was performed from sectional or full-arch die stone models. The contacts were assessed according to OXIS classification by a single calibrated examiner at Center 2. Prevalence was expressed as numbers and percentages. The Chi-square test was applied to determine the association of OXIS contacts across genders and arches. Results: The prevalence of O, X, I, and S contacts were 19%, 22.5%, 53%, and 5.5% in Center 1 and 6%, 1.5%, 75.5%, and 17% in Center 2, respectively. Significant results (p=0.005) were obtained in Center 1 when inter-arch comparison was performed and between the centers with respect to type of contact. No significant difference was obtained with respect to gender and OXIS contact areas. Conclusions: The present study confirmed OXIS contacts in both the centers. The ‘O’ and ‘X’ types of contacts were observed more in Center 1, whereas ‘I’ and ‘S’ contacts were observed more in Center 2.

Objective. Phototherapy devices have been found to be an effective method for treating neonatal hyperbilirubinemia. We reviewed the current literature to determine whether home-based phototherapy is more effective than hospital-based phototherapy for the treatment of neonatal hyperbilirubinemia. Method. PubMed, Scopus, Embase, Cochrane library, CBM, CNKI, and Wanfang Data were searched to collect the comparative study of home-based phototherapy versus hospital-based phototherapy for the treatment of neonatal hyperbilirubinemia. All studies were found to be of low risk based on Cochrane Collaborative Risk of Bias Tool. Data were statistically extracted and evaluated by RevMan 5.3 software. Result. A total of 259 neonates were included in the meta-analysis. Compared with hospital-based phototherapy, home-based phototherapy appeared more effective for the treatment of neonatal hyperbilirubinemia in reducing the rate of total serum bilirubin (standard mean difference = 0.32, 95% confidence interval = −0.22 to 0.86, P = .04); however, there was no significant difference in duration of phototherapy (standard mean difference = 0.59, 95% confidence interval = 0.28 to 0.90, P = .06) in the 2 groups. Conclusion. Home-based phototherapy was more effective than hospital-based phototherapy in treatment for neonatal hyperbilirubinemia; home-based phototherapy is an effective, feasible, safe, and alternative to hospital-based phototherapy for neonatal hyperbilirubinemia.

AbstractCongenital muscular torticollis (CMT) is a deformation characterized by unilateral shortening of the sternocleidomastoid muscle resulting in lateral inclination of the neck associated with contralateral torsion. The purpose of this study was to assess the role of physical therapy in infants with CMT according to the age when treatment was started. The study was conducted in the Physical Therapy Clinic “Therapy” in Pristina for a period of 1 year from June 2016 to June 2017. The number of infants diagnosed with a CMT was 130 (71 girls and 59 boys). The infants were examined two times during the study period. The first visit was at the baseline and the second after the intervention. Three comparative groups are created based on time to start treatment. The infants were treated for 3 consecutive weeks with five sessions per week with the same therapeutic procedure. In the first examination of infants, there was no significant difference between the groups (chi-square test = 0.78, p = 0.08), whereas in the second examination after the 15 therapeutic sessions there was significant difference in the improvement of all the groups treated with physical therapy. Significant result was achieved in mean range of motion in infants of the group aged 3.1 to 6 months (mean = –35.9 ± 12.3, 95% confidence interval [CI], –39.3 to –32.4, p < 0.001) and in the mean side flexion of group aged 3.1 to 6 months (mean difference = –24.5 ± 7.9, 95% CI, –16.9 to –9.7, p < 0.001). While exercises in the 6- to 9-month age group have shown less success, because the time of appearance for physical therapy has been delayed (mean difference = –23.5 ± 10.7, 95% CI, –15.6 to –8.4, p < 0.001). From the results obtained from this study, we can conclude that the early start of the physical therapy gives much better results.

Background: Malocclusion often occurs in children due to discrepancies between primary teeth and permanent teeth. An assessment of the severity of the malocclusion is necessary for establishing the diagnosis and determining the need for treatment. The Occlusal Feature Index (OFI) and Dental Aesthetic Index (DAI) are indices that assess the need for orthodontic treatment, but they use different weights. Purpose: This study aimed to compare the need for orthodontic treatment based on the OFI and DAI in 10–14-year-old children. Methods: The sample in this study is secondary data in the form of 66 study models pre-treatment in children aged 10–14 years at the Universitas Sumatra Utara (USU) Dental Hospital. All samples were collected based on inclusion and exclusion criteria. The measurement results were analysed statistically by the Chi-square test to see the comparison between the OFI and DAI. The results obtained are presented in the form of frequency and percentage. Results: For the OFI, 42.4% of the samples had no orthodontic treatment needed, 31.8% were indicated to treat, and 25.8% require mandatory treatment. For the DAI, 47% of samples had no/little treatment need, 25.8% had elective treatment need, 16.7% had treatment considered mandatory, and 10.6% treatment highly desirable. Based on the assessment to compare the OFI and DAI using the Chi-square test, p=0.001 was obtained. Conclusion: There was a significant difference in the need for orthodontic treatment between OFI and DAI in children aged 10–14 years at the USU Dental Hospital.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Abstract Background To analyze whether corneal refractive surgery (CRS) is associated with the distribution of different accommodative dysfunctions (ADs) and binocular dysfunctions (BDs) in civilian pilots. A further aim was to analyze the percentages and visual symptoms associated with ADs and/or BDs in this population. Methods One hundred and eight civilian pilots who underwent CRS from January 2001 to July 2012 (age: 30.33 ± 4.60 years) were enrolled, the mean preoperative SE was − 1.51 ± 1.15 D (range: − 1.00- − 5.00 D). Ninety-nine emmetropic civilian pilots (age: 29.64 ± 3.77 years) who were age- and sex-matched to the CRS group were also enrolled. Refractive status, accommodative and binocular tests of each subject were performed. Visually related symptoms were quantified using the 19-item College of Optometrists in Vision Development Quality of Life (COVD-QOL) questionnaire. The 19 items were summed to obtain visual symptom scores that might indicate visual dysfunctions. The chi-square test was used to analyze differences in percentages of ADs and/or BDs between the CRS and emmetropic groups. The Mann-Whitney U test was used to compare visual symptom scores between pilots with ADs and/or BDs and pilots with normal binocular vision. Results No significant difference was observed between the CRS and emmetropic groups in the overall prevalence of ADs and BDs (15.7% and 15.2% in the CRS and emmetropic groups, respectively; P = 0.185). ADs were present in 4.63% and 3.03% of the CRS and emmetropic group, respectively. BDs were observed in 11.1% and 12.1% of the CRS and emmetropic group, respectively, yielding no significant differences between the groups in the prevalence of ADs or BDs (AD: P = 0.094; BD: P = 0.105). Pilots with ADs and/or BDs had significantly more visual symptoms than pilots with normal binocular vision (p < 0.001). Conclusions CRS for civilian pilots with low-moderate myopia might not impact binocular functions. ADs and/or BDs commonly occur in both emmetropia pilots and pilots who undergo CRS, and pilots with ADs and/or BDs are associated with increased symptoms. This study confirms the importance of a full assessment of binocular visual functions in detecting and remedying these dysfunctions in this specific population.
