Abstract
Introduction: Periodontal disease is a common chronic inflammatory disease, considered as a primary cause of tooth loss due to the destruction of periodontal tissues. Various studies have shown that vitamin D has anti-inflammatory and anti-microbial properties and plays a significant role in musculoskeletal health. There is strong evidence that vitamin D deficiency may increase the likelihood of osteoporosis and osteopenia as well as chronic inflammatory diseases such as periodontitis.
Materials &Methods: This case–control study included 30 females with moderate or severe chronic periodontitis (CP) and 30 periodontally healthy females. The mean age of the CP group and the control group was 34 years. Indices of Probing depth (PD), clinical attachment level (CAL) and bleeding index (BI) as well as the serum level of vitamin D (1,25(OH)2D) were measured in both groups. The statistical analyses including t-tests, Pearson correlation coefficient and odd ratio.
Results: There was a significant indirect relationship between the serum level of vitamin D and the periodontal indices (p<0.05). The odd ratio (OR) measures showed that subjects with vitamin D dose of less than 10 ng/ml were 5.6 times more likely to have periodontitis compared to those with a normal dose of vitamin D ( p=0.03 ). Moreover, subjects with vitamin D dose of 10-29 ng/ml were about 1.46 times at a higher risk to develop periodontitis than those with sufficient dose of vitamin D (p>0.05).
Conclusion: It is recommended that serum levels of vitamin D in patients with chronic periodontitis be measured and then if necessary, treatment should begin.

Abstract
Introduction: Since the first permanent molar (FPM) as a first permanent tooth erupts between 6-7 years old and has a long period of eruption, it is the most caries prone tooth. One of the problems is inadequate knowledge of parents about the eruption time of the FPM; because these teeth erupt behind the deciduous teeth without a primary successor. In the present study, mothers' knowledge about its eruption time and its effect on health of these teeth was evaluated.
Materials & Methods: This cross-sectional study was conducted on 406 schoolchildren (7-9 years old) and their mothers using multi-stage sampling in Babol in 2017. Mothers completed the check list according to the study objectives. Clinical status of FPM was measured using DMFT (Decayed, Missed, Filled Teeth) index. Finally, data were analyzed with SPSS 18 using t-test and chi-square. Significance level was considered as p<0.05.
Results: Mothers’ awareness about the eruption time of FPM (p<0.001) was associated with higher ratio of children with sound FPM. Mothers’ education level was the most significant contributing factor to mothers' knowledge about FPM eruption time.
Conclusion: Mothers’ education and their knowledge about the FPMs eruption time were the major predictors of FPM caries status.

Abstract
Introduction: Although there are many studies about the internal anatomy of mandibular molars, there is still controversy over the frequency of middle mesial canals and isthmuses in the mesial root of mandibular molars and distolingual third root (Radix entomolaris) that it can be seen in any population, but it is more frequent in Asians and makes endodontic treatment difficult. Because of limited studies on the middle mesial canal, isthmus in north of Iran; therefore, the aim of this study was to investigate the frequency of these variations in the north of country.
Materials & Methods: In this retrospective cross-sectional study, The cone beam computed tomography (CBCT) images of 200 mandibular first molar teeth without any root canal treatment and completely erupted and developed were evaluated. Samples with open apex, internal root resorption, calcification, crown and extensive restoration were excluded. The patients’ gender, age, tooth location (left and right), count of canals in the mesial root, presence or absence of isthmus in mesial root, middle mesial canal and isthmus level in the mesial root and distolingual root (Radix entomolaris) were studied in three groups based on age; <20, 20-40 and >40.
Results: From 200 samples, 18 teeth (9%) had middle mesial canal, 38 teeth (19%) had isthmus in mesial root and 6 teeth (3%) had distolingual root (Radix entomolaris).
Conclusion: due to the high frequency of isthmuses, middle mesial canals and Radix entomolaris in the population, which cannot be ignored, missing and treating these spaces could be one of the main reasons for failure in root canal treatment. Therefore, it is advised to put more effort into detecting and completely clean and obturate these spaces in surgical and non-surgical endodontic treatments.

Abstract
Introduction: Residual oxygen-free radicals of bleaching agents before composite restorations can increase microleakage in enamel and dentin margins, and also various bleaching techniques are being developed using light sources. The present study was conducted to compare the effect of diode laser bleaching and LED activated bleaching on the microleakage of composite restorations.
Materials & Methods: This in-vitro study was conducted on 84 extracted human premolars in three groups: In group one, class-V cavities were prepared and the teeth (n=12) were restored with composite ten days after bleaching with 35% hydrogen peroxide with no activator. In groups two and three (n=36 each), the teeth were bleached with a Diode laser activator and LED, respectively. Thereafter, each group was divided into three subgroups (n=12), cavities were prepared and restored with composite three, five, and ten days after bleaching. Digital photographs were used to assess microleakage in the enamel and dentin margins. Data were analyzed using Friedman and Wilcoxon Signed Ranks tests (p<0.05).
Results: The lowest amount of microleakage in the enamel margin pertained to the diode laser ten-day subgroup (0.17±0.38) and the diode laser ten-day subgroup in the dentin margin (0.50±1.03). Also, the highest amount of microleakage in the LED group was in the three-day subgroup of the dentin margin (2.78±0.42). Five-day subgroup of diode laser-activated bleaching had a lower amount of microleakage compared to the control group (P=0.042).
Conclusion: It may be concluded that diode laser-activated bleaching with 35% hydrogen peroxide has a better effect on reducing microleakage with an interval of five to ten days, compared to the control and LED activated bleaching group.

Abstract
Introduction: Considering that nutrition plays a prominent role in the health of the elderly, oral health and the associated quality of life are very important for a healthy diet. The aim of this study was to investigate the association between the frequency of fruit and vegetable consumption and oral health-related quality of life (OHRQoL) among the elderly in Amirkola.
Materials & Methods: This study was part of the second phase of the Amirkola elderly cohort study conducted on 750 older people who underwent a special oral and dental examination in 2016-2020 using the Oral Health Questionnaire. The frequency of fruit and vegetable consumption was assessed with the Semi-Quantitative Food Frequency Questionnaire (SQFFQ), OHRQoL was assessed with the General Oral Health Assessment Index (GOHAI), and information on age, sex, history of systemic diseases, and the number of teeth was extracted from the full data set completed by specialists for each patient. Data were analyzed with SPSS 20 using the chi-square statistical test, ANOVA, and Pearson correlation coefficient. A value of p<0.05 was considered significant.
Results: Non-smokers and people with a higher level of education had a better OHRQoL (P=0.022 and P=0.036, respectively). There was no significant relationship between the frequency of fruit and vegetable consumption and OHRQoL, but a significant relationship was found between the frequency of fresh herb consumption and OHRQoL (p=0.005). In men, there was a significant relationship between the number of teeth and frequency of vegetable consumption as well as between OHRQoL and frequency of fresh herb consumption in men (P=0.048, r=0.096).In women, a significant relationship was observed between the frequency of total vegetable consumption and OHRQoL (p=0.021, r=0.129).
Conclusion: According to the results of the present study, it was found that the amount of fruit and vegetable consumption has no effect on improving the OHRQoL among the elderly of Amirkola city.

Abstract
Introduction: Candida albicans [C. Albicans] is an opportunistic microorganism of the normal flora that can cause infection in the oral mucosa. Nitric oxide [NO] is a free radical produced by macrophages and is highly associated with antifungal activities. The aim of this study was to evaluate salivary nitric oxide levels in patients with and without Candida Albicans-associated denture stomatitis.
Materials & Methods: In this cross-sectional study, 40 edentulous patients using dentures were divided into two groups: patients with and without denture stomatitis [DS]. Before laboratory detection of candida, an oral medicine specialist clinically confirmed the presence of DS. Saliva samples were collected by spitting method, and the Griess method measured NO. Chi-square and Mann-Whitney tests were used for statistical analysis. The level of significance was considered 0.05.
Results: The present study showed that the NO level was significantly higher in patients with DS than in patients without DS (P-value=0.002). In this study, the mean NO level in patients with DS was 166.5485±43.538 μM, while that was 118.0585±47.617 μM for patients without DS.
Conclusion: NO concentration in patients’ saliva can be associated with C. Albicans infection in the oral cavity. In the presence of Candida, the level of NO increases, and it seems that this increase is a kind of defense response to the presence of fungal infections.

Abstract
Introduction: Dental caries occurs at a specific site when the lactobacilli of that site reach 8% of the total bacteria in that site. The aim of this study was to investigate the antibacterial effect of pomegranate peel extract.
Materials & Methods: This experimental in vitro study was performed with 6 standard bacterial groups, including a group with 0.2% chlorhexidine and 4 groups with pomegranate extract concentrations of 10, 25, 50 and 100 mg/mL, as well as a blank plate group for determination of the zone of inhibition and a group of standard bacterial samples for determination of the minimum inhibitory concentration (MIC) on Lactobacillus acidophilus. The data were statistically analyzed using One-way ANOVA and Tukey Honestly Significant Difference (HSD) to measure the diameter of the growth inhibition zone. A value of P<0.05 was considered significant.
Results: The results of the inhibition zone diameter evaluation showed that different concentrations of the extract (10, 25, 50 and 100 mg/mL) had a positive inhibitory effect on Lactobacillus acidophilus. The results of the diameter of the inhibition zone using the disc plate method indicated that as the extract concentration increased, the antimicrobial effect on the bacteria increased and a significant difference was found between the diameters of the inhibition zone of four concentrations (16.5, 23.5, 26, 29.8 mm) (P<0.05). Examination of the MIC using the broth dilution method demonstrated that the effective amount of hydroalcoholic extract of pomegranate peel to prevent bacterial growth ranged from 12.5 to 25 (mg/ml). Moreover, chlorhexidine showed the highest growth inhibition zone (30 mm) in all studied groups.
Conclusion: According to the results of the current study, the hydroalcoholic extract from the pomegranate peel may have antimicrobial properties and it seems that the pomegranate fruit can be used as an antibacterial agent against Lactobacillus acidophilus, which can reduce the use of antibacterial chemical compounds with lower costs and side effects.
