Conclusion: The data of this study in proving the anti-biofilm and antibacterial effects of aloe vera extract showed that the expression of the target gene is reduced. It seems that this substance can be used as an alternative to oral hygiene chemicals.

Background and Aims: By using the image processing capability in Cone-Beam Computed Tomography (CBCT), obtained information can be improved. The aim of the present study was to investigate the effect of sharpen image processing filter in determining the external resorption of the root apical region in single-rooted teeth due to the proximity of the impacted tooth using CBCT.
Materials and Methods: In this laboratory study, the lateral surfaces of the apical region of the root of 40 healthy extracted teeth were artificially cut by bur and the teeth were randomly divided into four groups: control, low, moderate, and high resorption. After preparing CBCT of the teeth, the samples were then processed with and without an image sharpening processing filter and examined by two observers. The results of this study were analyzed by SPSS22 and Medcalc Statistical Software version 14. The significance level was considered P≤0.05 for all the statistical tests.
Results: Specificity (100%) and sensitivity (66%>) were either complete or very high for both modes without and with the sharpen filter. The overall accuracy (0.83>) was high in both cases and no significant difference was observed between the two overall accuracies (P>0.05). Statistical analysis of both image observations by two observers showed that the overall sensitivity and accuracy in the medium and high resorption groups was much higher than the low resorption group, but the specificity in all groups was 100%.
Conclusion: The results showed that the images with a sharpening filter did not increase the detection power compared to the unfiltered images. However, as no loss of accuracy was observed with this filter, it could be used as a processing filter.

Background and Aims: Oral health is a necessity and part of general health and its importance in childhood is more than ever. The aim of this study was to investigate the knowledge, attitude, and practice of parents in Delfan city-Iran about oral health of their 6-12-year-old children in 2021.
Materials and Methods: The present study was a descriptive-analytical study that was performed on 365 parents of 6-12-year-old children in Delfan city. Convenience sampling was used. The questionnaires included four sections: demographic information, knowledge, attitude and practice about oral health. Data were entered in SPSS23. Independent t-test, analysis of variance and Pearson correlation were used to analyze the data. Significance level was considered 0.05.
Results: The mean age of the subjects was 36.5±7.1. 201 of parents were mothers. Parents' knowledge and attitude were good and their performance was fair. There was a statistically significant relationship between all three variables of knowledge, attitude, and practice (P<0.00). Also, there was a statistically significant relationship between the knowledge and education (P<0.00), mother job (P<0.04), father job (P<0.00), and economic status (P<0.00). There was a statistically significant relationship between the attitude with education (P<0.00), mother job (P<0.04), father job (P<0.01), and economic status (P<0.01), There was a statistically significant relationship between practice and education (P<0.00), mother job (P<0.01), father job (P<0.00), and economic status (P<0.00) of parents.
Conclusion: The results of this study showed that there was a significant relationship between the knowledge, attitude, and practice with education level, job and economic status. Therefore, oral health education for parents with low educational and economic level should be highly considered.

Background and Aims: Atypical facial pain (AFP) is a chronic disease associated with local pain in the craniofacial area. A wide range of treatments including drug therapy, psychiatric methods and open surgery are used for its treatment. Opiorphin is a pentapeptide that can block pain and also has proven antidepressant effects. The aim of this study was conducted to investigate the opiorphin concentration in AFP patients and to compare it with healthy people.
Materials and Methods: This study was performed on 30 AFP patients and 40 healthy individuals. Unstimulated saliva was collected from both groups by spitting method. HAD-A (Hamilton Anxiety Test) and HAD-D (Hamilton Depression Test) questionnaires were completed for all patients and controls. Psychological interview with the patients and psychological analysis were performed to determine anxiety and depression scores. Data analysis was done using SPSS (ver.24) statistical software
Results: The subjects of two groups were homogeneous in terms of age and sex. The mean salivary opiorphin concentrations in the case and control groups were 1.8050±0.2923 and 1.8032±0.3682 ng/ml, respectively. According to the results of t-Test, no significant difference was observed in the mean opiorphin concentration between the AFP group and control group (P=1.000). According to the Pearson's test, no significant relationship was found between the opiorphin levels and the age, sex, and anxiety or depression score in the patient and control groups (P>0.05). Also, there was no remarkable correlation between initial VAS, duration of pain and previous treatments with opiorphin levels in the AFP patients (P>0.05). No significant correlation was found between the opiorphin concentration and menopausal period in the case and control women (P>0.05).
Conclusion: The results showed that most AFP patients had some degree of anxiety and depression. However, salivary opiorphin concentration did not significantly increase in the AFP patients.
