Abstract
Introduction: Effective performance in online education increasingly impacts the quality of classes and, consequently, student learning outcomes. This study aims to compare satisfaction levels and learning rates between online and face-to-face methods of teaching medical physiology.
Material & Methods: This cross-sectional descriptive-analytical study involved 79 medical students divided into two groups. The first group received instruction on heart physiology (5 weeks, one session per week) online via the Navid system, while the second group received face-to-face instruction. At the study's conclusion, both groups underwent the same test to assess learning outcomes, and satisfaction with the teaching methods was evaluated through a questionnaire. Data analysis was conducted using Stata 14 statistical software, employing logistic regression and linear regression models.
Results: The two groups differed in terms of the course studied, student nativeness, and satisfaction levels with the educational method. Satisfaction with online education was reported at 69%, compared to 65% for the face-to-face method. The average learning score for students in the online group was 12.93±0.12, while in the face-to-face group, it was 13.48±0.47. However, the linear regression model revealed no significant relationship between students' scores and specific educational methods (p=0.32). Significant relationships were observed between age, nativeness, and dormitory accommodation with satisfaction levels in online education. Conversely, none of the variables showed a significant relationship with satisfaction levels in face-to-face education.
Conclusion: Both e-learning and face-to-face methods demonstrated relatively similar effects on students' learning outcomes. However, satisfaction levels with online education appear to be influenced by variables such as age, nativeness, and dormitory accommodation.

Abstract
Introduction: Molar incisor hypo mineralization (MIH) is defined as extensive progressive enamel defects with a developmental origin. This study aimed to assess the prevalence and predictors of molar incisor hypo mineralization (MIH) in 6-12-year-old Iranian children 2022.
Materials and Methods: This cross-sectional study was conducted on all 6-12-year-old Iranian children residing in Ilam City, Iran, in 2022. For clinical oral examination, the surface of maxillary and mandibular permanent first molars and incisors was cleaned with a gauze and inspected and examined under adequate lighting and by using a dental explorer in wet conditions for the presence of opaque spots, surface degradation, and caries. The Chi-square and multiple logistic model were applied. Data were analyzed in SPSS V.24 at the level of 0.05 significance.
Results: Totally 1,016 children between 6-12 years participated in the study's first phase, 112 had MIH, yielding a prevalence rate of 11% for this condition. MIH was found in 53.2% of maxillary molars, 37.1% of mandibular molars, 9.7% of both maxillary and mandibular molars, 66% of maxillary incisors, 32% of mandibular incisors, and 2% of both maxillary and mandibular incisors. History of cesarean section (P<0.001), gestational diabetes (P=0.001), Chickenpox (P=0.041), Newborn jaundice (P<0.001), Otitis (P=0.036), Urinary tract infection (P=0.020), Antibiotic therapy (P<0.001) and Respiratory problems (P=0.047) had a positive association with MIH.
Conclusion: The prevalence of MIH was 11% in the study population, and cesarean section, gestational diabetes, medication intake during pregnancy, genetics, newborn jaundice, respiratory problems, otitis, urinary tract infection, antibiotic therapy, and chickenpox were significantly correlated with its occurrence.
