Nowadays pathology lesson presents in classrooms. Traditional learning doesn’t meet needs of present age. Web-based electronic learning (Elearning) is one of new learning methods. Also, Elearning has disadvantages. Combined learning is a combination of traditional and Elearning. The aim of this study was to compare the effect of traditional and combined learnings on learning of practical oral pathology lesson.
A weblog was designed containing of parts of practical oral pathology lesson. 30 dentistry students were divided in two equal groups. Before participation in classroom, one group studied subjects on weblog. Before traditional learning, evaluation of Elearning was done. Then, training was done in classroom for two groups. After a period, evaluation of combined and traditional learning for two groups was done. On later stage, position of two groups was exchanged beside that the contents were changed. Similar to early stage, evaluation of Elearning, traditional and combined learnings was done. Data were imported into statistical software and the effect of Elearning, traditional and combined learnings on students’ learning was compared.
Results showed that there is significant difference between mean scores of Elearning and traditional learnings (Pvalue=0.033) and between mean scores of traditional and combined educations (Pvalue=0.007).
It can be concluded that we can benefit from web-based learning as a complementary learning method beside the traditional learning for more influences on students’ learning and even can replace the traditional education.

The aim of this study was to determine purpose-based self-evaluation for the diagnosis of oral pathologic lesions among Isfahan dental school students in different educational levels so that the shortcomings and advantages of theoretical courses on the subject could be evaluated from the beginning to the end of the course.

In this cross-sectional, descriptive-analytical study a self-evaluation questionnaire was designed by students and approved by the Department of Oral and Maxillofacial Pathology academic staff in Isfahan Dental School. A total of 164 dental students in 6th, 10th and 12th semesters were included in the study using census sampling technique. The students answered the questions. Data were analyzed with SPSS 20 using two-way ANOVA and Kruskal-Wallis, Mann-Whitney and post hoc Tukey tests (α=0.05).

A total of 164 dental students from semesters 6 (68, 41.5%), 10 (51, 31.1%) and 12 (45, 27.4%) were evaluated. The mean scores of self-assessment were higher in students in the10th and 12th semesters compared to students in the 6th semester (p value = 0.001). Two-way ANOVA showed that the effects of educational level and sex on the mean self-evaluation score were significant (p value = 0.004 and p value = 0.006, respectively).

Self-evaluation scores of students to diagnose oral pathologic lesions were higher in students in the 10th and 12th semesters compared to those in the 6th semester, with a significant relationship with gender and age. In this context, female students exhibited higher scores compared to boys and the scores increased with age.

Diverse prevalence of oral mucosal lesions has been reported among different populations. There are few researches about the prevalence of oral mucosal lesions in Iran. The aim of the current study was to investigate the prevalence of oral mucosal lesions and associated factors in pathology department of Tehran Cancer Institute of Imam Khomeini Hospital from 2000 to 2010. This research was conducted on existing data. The patients’ age, gender, site of the lesion, type of the lesion and microscopic diagnosis were recorded. Prevalence of lesions were evaluated with (CI=%95) all data were analyzed by x2 Test under spss (16). Oral mucosal lesions were present in 784 cases out of 40092 cases (1.96%). Epithelial lesions were found to be the most prevalent oral mucosal lesions of all (90%). The most common location reported for the lesions was the lips (26.8%).The mean age for the patients was 43±17 years of age and there was no association found between the type of the lesion and the sex of the subjects (p<0.09). Squamous Cell Carcinoma was the most prevalent mucosal lesion which is a malignant epithelial tumor and its early detection is essential.
