Abstract
Background and purpose: In recent decades, various efforts have been made to replace synthetic materials with natural disinfectants that have less disadvantages and lead to similar or even better results. The present study was conducted to compare the effect of Artemisia aucheri and Zataria multiflora as natural disinfectants with those of Deconex and sodium hypochlorite as two industrial disinfectants on Candida albicans.
Materials and methods: This experimental study was conducted in 128 resin acrylic dentures. After the inoculation of C. albicans on each denture, they were divided into four groups, each containing 32 dentures. Deconex, Sodium hypochlorite, Artemisia aucheri, and Zataria multiflora were administered in each group in four densities (0.1, 0.01, 0.001, and 0.0001). The data were analyzed in SPSS V19 applying t-test.
Results: The four disinfectants were applied for 10 and 60 min. Deconex showed the highest disinfection effect on samples (P<0.05). There were no significant differences between the effect of Artemisia aucheri and Zataria multiflora after 60 min and 10 min. However, it was found that the potency of Artemisia aucheri and Zataria multiflora increased after 60 min.
Conclusion: Current findings showed chemical disinfectants with higher potency in short-time intervals, compared to the natural ones. But, after a longer period of time, Artemisia aucheri and Zataria multiflora exerted similar effects as those of the synthetic disinfectants.

Abstract
Background and purpose: This study was carried out to determine the relationship between maxillary central incisors and incisive papilla in complete dentures and compare that with dentate people.
Materials and methods: In this descriptive-analytical study, the horizontal distance between the maximum prominence of labial surface of maxillary central incisors to the middle and posterior points of incisor papilla was measured using a caliper, on the casts prepared from 30 dentate patients and 30 complete dentures made in Dental School affiliated with Mazandaran University of Medical Sciences.
Results: Average distance between the midpoint of incisive papilla to the labial surface was 9.641±0.866 mm in dentate people and 8.851±1.504 mm in complete dentures. The mean distance between the posterior point of incisive papilla and the labial surface was 12.815±1.264 mm in dentate people and 10.788±1.837 mm in complete dentures. Independent t-test showed significant difference between the two groups in mean distance between the midpoint and the labial surface (0.790 mm, P<0.05). The distance between the posterior point and the labial surface was also found to be significantly different between the two groups (2.026±0.407 mm, P<0.001).
Conclusion: According to the limitations of this study, the midpoint of incisive papilla is suggested to be more reliable than posterior point in assessing the position of anterior maxillary teeth among complete denture patients.

Abstract
Background and purpose: Edentulism is a dental system defect that has a serious impact on quality of life. This study aimed to compare oral health-related quality of life (OHRQoL) between mandibular edentulous patients with conventional dentures (CCD) and implant-supported overdentures (IOD).
Materials and methods: In this retrospective cohort study, 88 mandibular edentulous patients were selected in two groups of CCD and IOD. After registering the demographic information, the OHRQoL questionnaire (OHIP-14) was completed by each patient. Quantitative data were described with mean (standard deviation) and qualitative with number (percentage). Data analysis was done with SPSS21 statistical software. A significance level of 0.05 was considered.
Results: Out of 88 patients participating in this study, 39 were men and 49 were women. The findings showed that the mean OHRQoL score had no significant relationship with age and gender of the patients (P>0.05). The total score of OHRQoL in the CCD group was significantly higher than the IOD group (12.36 ± 8.14 vs. 8.82 ± 6.08; P=0.02).
Conclusion: According to the results of the study, gender and age did not have much effect on the OHRQoL. The OHRQoL of people who used IOD was better than those who used CCD.
