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

This study evaluated the accuracy of three electronic apex locators (Root ZX, Novapex, and Justy II) in root canal length determinations using different apical file sizes, considering the apical constriction (AC) and the major foramen (MF) as anatomic references. The diameter of the apical foramina of 40 single-rooted teeth was determined by direct visual measurement and the master apical file was established. Electronic measurements were then performed using 3 instruments: the selected master apical file (adjusted file), one size smaller (intermediate file), and two sizes smaller (misfit file). The distances from the tip of files fixed in the canals to the MF and to the AC were measured digitally. Precision at AC and at MF for the misfit, intermediate and adjusted apical files was as follows: 80%/88%/83% and 78%/83%/95% (Root ZX); 80%/85%/80% and 68%/73%/73% (Novapex); and 78%/80%/78% and 65%/78%/70% (Justy II). Considering the mean discrepancies, statistically significant differences were found only for the adjusted file at MF, with Root ZX presenting the best results at MF. The chi-square test showed significant differences between the acceptable measurements at AC and at MF for the Justy II and Novapex (± 0.5 mm) regardless of file adjustment. Under the conditions of the present study, all devices provided acceptable electronic measurements regardless of file adjustment, except for Root ZX which had its performance improved significantly when the precisely fit apical file was used. Justy II and Novapex provided electronic measurements nearest to the AC.

Abstract Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA). Materials and Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean ± standard deviation [SD], 33.2 ± 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test. Results: Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m2 ± 6.5) than for the control group (22.7 kg/m2 ± 3.5; P &lt; .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm ± 6.02; 129.1 mm Hg ± 17.55) than for the control group (35.6 cm ± 3.52; 114.1 mm Hg ± 13.67; P &lt; .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P &lt; .05), but no significant difference in palatal shape was found. Conclusion: The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group.

Introduction: The COVID-19 pandemic has challenged the healthcare system’s capacities around the world. Due to the alarming situation, medical activities have been restricted to allocate resources to treat COVID-19-infected patients. However, medical emergencies still need urgent medical intervention. Considering the lack of reliable data regarding spinal surgeries during the COVID-19 pandemic, the present study sought to analyze the pattern of spinal surgeries in KSA. Methodology: A case series of patients who had urgent spine surgeries during COVID-19 pandemic was conducted in a tertiary care hospital. Data on patients’ demographics, COVID-19 test result, American Society of Anesthesia Score, SSS grade, diagnosis, and data related to surgery and postoperative findings were collected. All collected data were then processed and analyzed. Surgical outcomes based on source of admission were compared using Chi-square test. Result: A total of 63 patients who underwent spine surgery during the COVID-19 pandemic were included. The mean age of the patients was 53 ± 18 years and males were predominant (59%). The positive COVID-19 patients were 3%. Almost half of the patients were classified into ASA II. The majority were categorized into grade B (65%) according to SSS. The frequently diagnosed condition was fracture (33%), followed by spinal stenosis (18%) and metastatic (10%), while the most mentioned location was lumbar (61%). Postoperative complications were found in 11% of the patients. The readmission rate within 30 days, unplanned return to OR and ICU admission were 19%, 13%, and 11%, respectively. While the mean duration between admission and surgery was 8 ± 20 days, the mean duration of length of stay was 20 ± 29 days. Further, a significant association was seen between the admission source and the surgical procedure performed and surgical indication. Conclusion: It has been demonstrated that the surgical intervention was only provided to patients requiring immediate or urgent spinal management. However, the length of hospitalization and duration between hospital admission and surgery was substantially prolonged. Further studies are warranted to determine the factors leading to prolonged hospitalization and time between hospital admission and surgery.

SummaryThe aim of the study was to determine the status of SE in people with physical disabilities (PwPD) and compare SE scores between active and inactive individuals. The sample of PwPD (n = 186) was divided into two groups of those who are regularly participating in sport (active; n = 88) and those who are not participating in any sport in their leisure (inactive; n = 98). The Rosenberg Self-Esteem Scale (RSES) was used as a primary research method. 10-item scale measures global self-worth by measuring positive and negative feelings about the self. Higher scores (from 10 to 40 points) indicate higher SE. The Pearson chi-square test was used to determine the differences of 10 RSES items and total scores between active and inactive PwPD. We found that the mean score of RSES in PwPD was 28.83 points; active PwPD observed total score of RSES 30.01 points and group of inactive PwPD showed the lowest SE by achieving 27.76 points. Mean scores comparison of each RSES item between active and inactive PwPD revealed higher SE in the group of active PwPD. Significantly higher SE was presented by 4 from 10 RSES items and by total score in the group of active PwPD. The results of our study confirmed that actively living PwPD have significantly higher SE comparing those PwPD who are living sedentary life style.
