Abstract
Background & Aim: The antiseptic characteristic of root canal filling materials seems very critical in pulpectomy procedure to eliminate residual pathogens of root canals. The aim of this laboratory study was to compare the antifungal activity against Candida albicans of ZOE with calcium hydroxide root canal filling pastes (Sealapex and Metapex).
 Methods: An exprimental study was conducted and agar diffusion inhibitory test was used to assess antifungal activity. Thirty 10-cm-diameter dishes with four mm thickness of agar inoculated with Candida albicans were used and four five-mm-diameter wells per dish at equidistant points were filled with the three test root canal filling pastes (ZOE, Sealapex and Metapex) and distilled water as a negative control. After incubation of the plates at 37oC for 48 h, the diameter of the zones of fungal growth inhibition produced around the wells was measured (in mm) with a caliper. Kruskall-Wallis test was used to analyse the data. Level of significancy was less than 0.05.
Results: Kruskall-Wallis test indicated that there were statistically significant differences (p<0.001) among median of the zones of fungal growth inhibition produced by the 3 different materials. Median diameter of inhibition zones of fungal growth was significantly higher in ZOE than both Metapex (p<0.001) and Sealapex (p<0.001).
Conclusion: Based on the results of this study, it appears that ZOE has more antifungal activity than Metapex and Sealapex.

Abstract
Background: The amount of fluoride uptake is an important factor of varnish fluoride to choose it for use. The purpose of this study was to compare of primary teeth’s fluoride uptake among three kinds of sodium fluoride varnishes (Ariadent, Voccu and Soltan).
Materials and Methods:An experimental study was done on  three kinds of sodium fluoride varnishe (including Ariadent, Soltan and Vocco ones). Twenty-five extracted primary molar were set in each groups. Amount of fluoride uptake and efficacy among these three varnish models were evaluated. Each tooth was devided in halfs in mesiodistal direction while each half was randomly selected in case and experimental subgroups. Roots were also removed. All surfaces; except enamel, was covered by polish and then varnishefluoride was applied on enamel surface. For 24 hours followed by inserting to 10 cc deionized water. Two steps of adding KOH 0.2 mol and percloric acid (HClO4) 0.5 mol each one for 30 seconds were performed. All specimens were soluted in 10 cc deionized double washed water and shaked with shaker. Next all samples were prepared by Acid Etch Enamel Biopsy method for determining fluoride concentrations with spectrophotometer. Data  was analyzed by variance, one way variance and Games-Howell test. The level of significancy was less than 0.01.
Results:The results showed that fluoride uptake was different for studied varnishes while applicating Sultan varnish showed highest fluoride amount in teeth. Comparison between Vocco and Ariadent showed significant difference as well as Sultan and Ariadent varnish (p-value 0.014 and 0.016 consequenly), but there was no significant difference between Vocco and Soltan varnishes.
Conclusion: Fluoride uptake could help us to choose varnish beside with other characteristics like easily applying, the color remaining on teeth, packing, flavor, durability. The results and findings proved that among three evaluated sodium fluoride varnishes, the Sultan showed better efficacy and potency in aspect of tooth uptaking fluoride.

Abstract
Introduction: There are several studies in relation to dermatoglyphics with some fields in dentistry. The objective of this study is evaluation of relation between dermatoglyphics and hypodontia in cases with congenital hypodontia.
Materials & Methods: In this case-control study, 20 cases with hypodontia and 20 cases as control group were selected from those referred to Mashhad Dental School. Ink  method was used in this study.Data analyzed with SPSS, and T-test with significancy of 0.05 was used for statistical analyses.
Results: T-test showed no significant difference between the mean number of ridge count in the left and right hands of the subjects. .T-test showed significant difference between both groups in frequency of loop pattern type of the finger tips.  (P=0.01). Also there is no significant difference between both study groups in frequency of types of arch and whorl patterns of the finger tips.
Conclusion: Dermatoglyphics may be considered in diagnosis of hypodontia; however further researches in large groups especially according to dermatoglyphics' qualitative characteristics in cases with congenital hypodontia is needed.

Abstract
Background and Aims: Disability is a global concern, involving a wide range of world’s population in all ages and social classes. Persons with disabilities have diverse personal factors with differences in gender, age, socioeconomic status, sexuality, ethnicity, or cultural herit­age. Women with disabilities experi­ence the combined disadvantages associated with gender as well as disability. People who experience mental health conditions or intellectual impairments appear to be more disadvantage in many settings than those who experience physical or sensory impairments. Children and adolescents with disabilities appear to have poorer oral health than their nondisabled counterparts. Variable access to dental care, inadequate oral hygiene and disability-related factors may account for the differences.
Materials and Methods:  This observational study includes 51 mentally disabled school children aged 6 to 17 years old, live in Tehran, district18. All patients were examined for Plaque Index, Gingival Bleeding Index, DMFT/DMFT and Calculus Index by a dentist and under fluorescent light, by means of a mirror and a periodontal probe.
Results: Average Plaque Index of the students was 1.74±0.66, GBI was 0.28, average of calculus Index was 0.06, DMFT was 5±4.3 and DMFT was 2.3±4.9.
Conclusion: Results of this study confirms that disabled children of Tehran have poorer oral and dental condition in comparison with normal children. Therefore preventive oral hygiene programs and easy-access dental services allocating to disabled people are needed.
