Aims: The position of lower incisor has been of significant concern when seeking orthodontic treatment plan, it has been recognized as one of diagnostic key and play an important in the development of normal occlusion and facial pattern. This study was aimed at the determination of lower incisor position and its possible association with different sagittal malocclusions and facial patterns. Study Design: Descriptive Cross-sectional Study Place and Duration of Study: Department of Orthodontics Institute of Dentistry Liaquat University Medical and Health Sciences (LUMHS) Jamshoro between June 2019 to July 2020. Methodology: Ninety-seven pre-treatment lateral cephalometric radiographies were taken, and they were classified sagittally into skeletal class I, II and III, and vertically into normodivergent, hyperdivergent and hypodivergent facial pattern using ANB and SNMP, respectively. Lower incisor position was assessed by means of FMIA and IMPA. One way analysis of variance (ANOVA) was applied to check any association between lower incisor position and sagittal malocclusion and facial pattern. P value of 0.05 was considered statistically significant. Results: The study sample consisted of 97 patients. The mean age of the patients was 25.55 SD ±3.93. The mean SNMP value was 28.84 SD ±7.354 and mean ANB value 4.809 SD ±3.85. Mean Incisor position based on IMPA was 98.598 SD ± 9.413 and FMIA 54 SD ±9.995. Intra and interobserver reliability was assessed with intraclass correlation coefficient values ranging between 0.825 and 0.990 respectively. The ANOVA test results showed significant relationship between the sagittal malocclusion and incisor position with P value .036. The Bonferroni analysis indicated that statistically significant association existed in term of lower incisor position between Class II and Class III malocclusion with P value .047. Test results further indicated that there is no significant difference in the position of lower incisor in relation to facial pattern with P value .355. Conclusions: Statistically significant association was found between lower incisor position with respect to the sagittal malocclusion. However, no significant association was found between facial pattern and lower incisor position.

BACKGROUND A deep overbite may be due to an underlying skeletal or dentoalveolar component that may influence the treatment plan. The purpose of this study was to evaluate and compare the different components of deep bite malocclusion and normal occlusion. METHODS This was a case control study. Lateral cephalograms and study casts of normal (N = 50) and deep overbite (N = 50) subjects were used to evaluate skeletal and dentoalveolar components. Data was analysed statistically by independent t - test. RESULTS The significant skeletal contributing factors were gonial angles, mandibular plane, maxillary plane angle & ramus / Frankfort horizontal. An increased curve of Spee and decreased mandibular first molar height were predominant dental variables in the deep overbite group. The inclination of the upper incisors & lower incisors height did not show a statistically significant difference between the two groups. CONCLUSIONS The counterclockwise rotation of the mandible and the increased curve of Spee were the dominant features of deep bite malocclusion. This analysis of deep overbite components could help clinicians design individualised mechanotherapy based on the underlying cause rather than being prejudiced toward conventional mechanics when correcting with a deep overbite malocclusion.

Abstract Background Patellofemoral pain is a common condition. The Kujala score is a well-established scoring system to assess anterior knee pain and has been translated into many languages including Arabic. The purpose of this cross-sectional study is to culturally adapt the Arabic version of the Kujala score and determine its validity. Methods The Kujala score is composed of 13 multiple-choice questions. We modified two questions in the score; running and squatting, and were replaced with questions related to walking on different terrain and prostration, each with the same number of answer choices as the original questions so as not to affect the final score. These modifications were written in Arabic by the same group who translated and validated the original score into Arabic. The original and modified Kujala scores was printed and given to patients complaining of patellofemoral pain to be filled during their visit to the orthopedic outpatient clinics. Final scores for the original and modified questionnaires were calculated. Data was analyzed using SPSS statistics version 21.0 measuring Cronbach’s alpha, intraclass correlation coefficient, and Pearson correlation. Results Ninety-four patients were included in the study, 28 (29.8%) men and 66 (70.2%) women. The mean age for the included patients was 43.67 (± 14.46) years. The mean score for the modified initial questionnaire was 63.91 (± 16.32), and the mean score for the modified re-test questionnaire was 66.52 (± 17.50). There was a statistically significant difference between the mean scores (p = 0.041), with a mean difference of 1.97 (95% CI 0.08 to 3.856). We found a significant strong correlation between the score before and after changing the questions with a p value of < 0.001. Conclusions The culturally modified Arabic Kujala questionnaire is shown to be a valid, well-designed tool and an appropriate method of measuring patellofemoral pain.

Diabetes mellitus is a disease that often causes diabetic nephropathy complications due to persistent hyperglycaemia. Phaleria macrocarpa (scheff. Boerl) is one of the plants that has been widely used in the treatment of diabetes mellitus, but its effect on the risk of diabetic nephropathy is still unknown. A dose of 300mg / 200gbb / day is known as an effective dose that can significantly reduce blood sugar levels in diabetic rat. The Streptozotocin Effect (STZ) causes damage to the pancreas and causes hyperglycaemia. This study aims to compare the effect of Phaleria macrocarpa (scheff. Boerl) fruit extracts on urea and creatinine levels as a parameter of kidney function in hyperglycaemic mouse models. The study was carried out experimentally using the post-test only with control group design. Fifteen white rats were divided into 3 groups. All rats were induced with 40 mg / 200gbb of Streptozotocin (STZ) to experience hyperglycaemia. Group I as negative control was given aquades. Group II was given ethanol extract of Phaleria macrocarpa (scheff. Boerl) with a dose of 300 mg / 200gbw / day. Group III was given Metformin at a dose of 150 mg / 200gbw / day. On the 22nd day of treatment, blood specimens were taken for examination of urea and creatinine levels. The research data were statistically analyzed with α <0.05; CI95%. The mean of urea levels in Group I (79.80 ± 25.09 mg / dl), II (76.00 ± 22.59 mg / dl and III (59.60 ± 6.35 mg / dl). Kruskal-Wallis test results showed no significant difference in urea levels between treatment groups (p value = 0.273; CI95%). The mean of creatinine levels in Group I (0.68 ± 0.07 mg / dl), II (0.63 ± 0.14 md / dL) and III (0.98 ± 0.25 mg / dL). One Way Anova and Post hoc test results showed a significant difference in mean creatinine levels between Groups I and III (p = 0.014; 95% CI) and II with III ( p value = 0.006; CI95%). the results of this study can be concluded that the extract of Phaleria macrocarpa (scheff. Boerl) fruit flesh at a dose of 300 mg / 200gbb has better effectiveness than metformin dose 150 mg / 200gbb in repairing the kidney function of hyperglycaemia rats.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

Abstract Background Chronic rhinosinusitis (CRS) is a common inflammation of the nose and the paranasal sinuses. Intractable CRS cases are generally treated with endoscopic sinus surgery (ESS). Although the effect of ESS on CRS symptoms has been studied, the pattern of symptom improvement after ESS for CRS is yet to be investigated. The aim of this study was to determine the magnitude and sequence of symptom improvement after ESS for CRS, and to assess the possible preoperative factors that predict surgical outcomes in CRS patients. Methods This was a longitudinal prospective study of 68 patients who had CRS (with or without nasal polyps). The patients underwent ESS at King Fahd Hospital of the University, Al Khobar, Saudi Arabia. The Sino-nasal Outcome Test-22 (SNOT-22) questionnaire was used for assessment at four time points during the study: pre-ESS, 1-week post-ESS, 4 weeks post-ESS, and 6 months post-ESS. Results The difference between the mean scores recorded for the five SNOT-22 domains pre-ESS and 6 months post-ESS were as follows: rhinologic symptoms (t-test = 7.22, p-value = < 0.001); extra-nasal rhinologic symptoms (t-test = 4.87, p-value = < 0.001); ear/facial symptoms (t-test = 6.34, p-value = < 0.001); psychological dysfunction (t-test = 1.99, p-value = 0.049); and sleep dysfunction (t-test = 5.58, p-value = < 0.001). There was a significant difference between the mean scores recorded for the five domains pre-ESS and 6 months post-ESS. Rhinologic symptoms had the largest effect size (d = 1.12), whereas psychological dysfunction had the least effect size (d = 0.24). The only statistically significant difference in the SNOT-22 mean scores recorded 4 weeks post-ESS was observed between allergic and non-allergic patients (t = − 2.16, df = 66, p = 0.035). Conclusion Understanding the pattern of symptom improvement following ESS for CRS will facilitate patient counselling and aid the optimization of the current treatment protocols to maximize surgical outcomes and quality of life.

Abstract Background The replica technique with its modifications (negative replica) has been used for the assessment of marginal fit (MF). However, identification of the boundaries between prosthesis, cement, and abutment is challenging. The recently developed Digital Image Analysis Sequence (DIAS) addresses this limitation. Although DIAS is applicable, its reliability has not yet been proven. The purpose of this study was to verify the DIAS as an acceptable method for the quantitative assessment of MF at cemented crowns, by conducting statistical tests of agreement between different examiners. Methods One hundred fifty-one implant-supported experimental crowns were cemented. Equal negative replicas were produced from the assemblies. Each replica was sectioned in six parts, which were photographed under an optical microscope. From the 906 standardized digital photomicrographs (0.65 μm/pixel), 130 were randomly selected for analysis. DIAS included tracing the profile of the crown and the abutment and marking the margin definition points before cementation. Next, the traced and marked outlines were superimposed on each digital image, highlighting the components’ boundaries and enabling MF measurements. One researcher ran the analysis twice and three others once, independently. Five groups of 130 measurements were formed. Intra- and interobserver reliability was evaluated with intraclass correlation coefficient (ICC). Agreement was estimated with the standard error of measurement (SEM), the smallest detectable change at the 95% confidence level (SDC95%), and the Bland and Altman method of limits of agreement (LoA). Results Measured MF ranged between 22.83 and 286.58 pixels. Both the intra- and interobserver reliability were excellent, ICC = 1 at 95% confidence level. The intra- and interobserver SEM and SDC95% were less than 1 and 3 pixels, respectively. The Bland–Altman analysis presented graphically high level of agreement between the mean measurement of the first observer and each of the three other observers’ measurements. Differences between observers were normally distributed. In all three cases, the mean difference was less than 1 pixel and within ± 3 pixels LoA laid at least 95% of differences. T tests of the differences did not reveal any fixed bias (P > .05, not significant). Conclusion The DIAS is an objective and reliable method able to detect and quantify MF at ranges observed in clinical practice.

The aim of this study was to evaluate the effect of implant surface treatment with carboxyethylphosphonic acid and fibroblast growth factor 2 on the bone–implant interface during the osseointegration period in vivo using an animal model. The present research was carried out in six minipigs, in whose left tibia implants were inserted as follows: eight implants with a standard surface treatment, for the control group, and eight implants with a surface treatment of carboxyethylphosphonic acid and immobilization of FGF-2, for the test group. At 4 weeks after the insertion of the implants, the animals were sacrificed for the histomorphometric analysis of the samples. The means of the results for the implant–bone contact variable (BIC) were 46.39 ± 17.49% for the test group and 34.00 ± 9.92% for the control group; the difference was not statistically significant. For the corrected implant–bone contact variable (BICc), the mean value of the test group was 60.48 ± 18.11%, and that for the control group, 43.08 ± 10.77%; the difference was statistically significant (p-value = 0.035). The new bone formation (BV/TV) showed average results of 27.28 ± 3.88% for the test group and 26.63 ± 7.90% for the control group, meaning that the differences were not statistically significant (p-value = 0.839). Regarding the bone density at the interthread level (BAI/TA), the mean value of the test group was 32.27 ± 6.70%, and that of the control group was 32.91 ± 7.76%, with a p-value of 0.863, while for the peri-implant density (BAP/TA), the mean value of the test group was 44.96 ± 7.55%, and that for the control group was 44.80 ± 8.68%, without a significant difference between the groups. The current research only found a significant difference for the bone–implant contact at the cortical level; therefore, it could be considered that FGF-2 acts on the mineralization of bone tissue. The application of carboxyethylphosphonic acid on the surface of implants can be considered a promising alternative as a biomimetic coating for the immobilization of FGF-2. Despite no differences in the new bone formation around the implants or in the interthread or peri-implant bone density being detected, the biofunctionalization of the implant surface with FGF-2 accelerates the mineralization of the bone–implant interface at the cortical level, thereby reducing the osseointegration period.

ABSTRACT Objective: The purposes of this investigation were to determine the horizontal distances between the mandibular posterior teeth and the WALA ridge in a sample of Peruvians with normal occlusion and to compare them by tooth type, sex, arch side, and age groups. Methods: 65 dental casts of subjects with normal occlusion were collected. Posterior teeth, except for third molars, were evaluated. The horizontal distances between the occluso-gingival midpoints of the buccal surfaces (FA points) of each tooth and the WALA ridge were measured using a modified digital caliper. The values between each different tooth type within the sample were compared using the ANOVA and Scheffe tests, while comparisons by sex, arch side and age groups, using the Student’s t-test. Results: The mean distances in the sample was 0.96 mm for first premolars, 1.45 mm for second premolars, 2.12 mm for first molars and 2.55 mm for second molars. Statistically significant differences between each of the four tooth types were found. There were no significant differences found between sex, arch side and age groups. Conclusion: The horizontal distances between the mandibular posterior teeth and the WALA ridge increased progressively from the first premolars to the second molars in Peruvians with normal occlusion. The WALA ridge was a good landmark to evaluate the positions of posterior teeth in Peruvians with normal occlusion.

Background & Method: We conducted a double blinded study at Index Medical College Hospital & Research Centre, Indore. The sample size was determined to be minimum of 120 cases as based upon previous years admission due to acute bronchiolitis. Initially, 146 cases were included in the study out of which 23 cases dropped out of the study after giving consent by guardian for participation in the study as they left against medical advice from the hospital. Result: The mean difference of CSS between 0 minutes to 60 minutes of nebulisation between groups in all cases was 0.4 ± 0.6, between 60 minutes and 4 hours was 0.8 ± 0.6, between 4 to 8 hours was 0.7 ± 0.6, between 8-12 hours was 0.6 ± 0.4, between 12-24 hours was 1.6 ± 0.9 and between 24-48 hours was 1.9 ± 0.9.The mean values and resultant p-value of ANOVA of various nebulising agents used for improvement in CSS shows significant association between various nebulising agents used along with improvement in CSS at the end of assessment at 48 hours of treatment. Conclusion: This study was conducted to establish the efficacy of each nebulisation agent (i.e. adrenaline, 3% hypertonic saline and normal saline) currently used and compare the outcomes as there is not enough evidence amongst Indian population on level of efficacy of each drug in causing improvement in symptoms and signs in various severities of bronchiolitis in early childhood. Comparison of significant improvement in mean difference in CSS at various intervals in all cases compared between groups by post hoc test revealed non-significant difference (p-value 0.700) between 3% hypertonic saline and normal saline.
