Abstract

Among natural food sources with antimicrobial activities, ginger rhizome has been used as widely grown food spices and medicinal crops for centuries. Furthermore, it possess antifungal and antioxidant properties due to the phenols – related constituents (gingerols) that constrain the growth of many Gram positive and Gram negative bacteria including some periodontal bacteria. The Actinomycetem comitans is a portion of the normal microbiota in numerous healthy individuals but is also a major etiological agent in some aggressive and chronic types of periodontitis. The present study was conducted to test the effect of aqueous and alcoholic ginger extracts on the growth of Aggregatibacter actinomycetem comitans in comparision to 0.2% chlorohexidine gluconate mouth wash and distilled water in vitro, determination of ginger extracts minimum inhibitory concentration and minimum bactericidal concentration and detection of active ingredients of ginger extracts by using the high-performance liquid chromatography as well as chemical elements.

Abstract

Periodontal diseases are inflammatory diseases that affect the periodontium which lead to alveolar bone and attachment loss. Breast cancer is the most common cancer in women worldwide. Expression of (VEGF) is elevated in both diseases and it is the marker of angiogenesis related to cancer development. 1. To determine the periodontal health status and the serum levels of (VEGF) in women with breast cancer in comparison to women without breast cancer. 2. To correlate between serum levels of VEGF with clinical periodontal parameters (PLI, GI, BOP, PPD, and CAL) in women with breast cancer in comparison to women without breast cancer. Eighty women with age ranged from (30- 60) years old, 40 women with breast cancer and another 40 women without. Periodontal health status were taken for all participants and then they were subdivided into four groups: the (BC +CP) group which included participants with breast cancer and chronic periodontitis (n=20), the (BC+ G) group included participants with breast cancer and gingivitis (n=20), the (CP) group which included participants with chronic periodontitis only (n=20) and the (G) group which included participants with gingivitis only (n=20). Other than breast cancer, all subjects were systemically healthy females. Periodontal health status was determined by clinical periodontal examination of (PLI, GI, BOP, PPD and CAL). Blood samples were collected from each participant, serum levels of VEGF were determined by enzyme -linked immune-sorbent assay (ELISA). The results of this study showed that the median values of PLI and GI were slightly increased in BC+G group in comparison to other groups with non-significant differences, the percentages of BOP showed highly significant differences among the groups (P <0.01). The median values of PPD showed slight increase in BC+CP group than CP group with non-significant differences. Median values of CAL were increased in CP group than BC+CP group with non-significant differences. VEGF serum levels were elevated in BC+CP group than other groups with nonsignificant differences. Also by using Spearman’s rank Correlation Coefficient, serum levels of VEGF were correlated positively with all clinical periodontal parameters. VEGF serum level could be associated with progression of both periodontal diseases and breast cancer.

Abstract

Gypsum products (dental plaster and stone) are widely used in dentistry. However, the main problem with any gypsum products is reproduction of fine details and dimensional stability. The current study was conducted to assess the effect of incorporating various additives (i.e. cured resin, pulverised stone, pulverised plaster, and glass fibers) and drying method on compressive strength of gypsum products. A total of 160 specimens were divided into 2 groups according to the method of drying (air and microwave). For each drying method, each group was subdivided depending on the type of material used into 2 groups; dental plaster and dental stone. Variuos additives were used for reinforcement; cured resin, pulverised plaster, pulverised stone, and glass fibers. The unmodified group was considered as control. The specimens were dried and the compressive strength test was applied on all specimens. All specimens' data were statistically analysed via ANOVA, Tukey and independent T tests.The compressive strength of gypsum products was significantly influenced by the type of additive used. The specimens reinforced with glass fibers, cured resin, pulverised plaster, and stone had a greater value of mean compressive strength compared with unmodified groups. Statistically, highly significant differences were observed among all dried groups (P≤0.001). As well, the microwave specimens were more resistant to compressive loadings than air dried specimens. No significant differences, however, were recorded between the two drying methods (P>0.05).The glass fibers have a significant effect on compressive strength of gypsum products. The pulverised particles and cured resin can be added at 1 % by weight to enhance the mechanical properties of plaster and stone. Microwave drying for 5 minutes can fasten the drying time and permit early manipulation of plaster and stone models.

Abstract

Propolis is consist of various amounts of resins and beeswaxes that produced by the honeybees from different natural plants, as leaf buds and flowers. It is a sticky and dark-brown color material that produced by honeybees from natural plants that the bees mixed it with wax and applied it in building, construction and adaptation of the nests specially in repair cracks and defects in the bees hive. They have been used in medical folk or medical traditional since times of ancient. It is now known to be natural medical treatment with, antifungal, antibacterial, antioxiditive, antitumor and mmunomodulatory properties. These medical properties of propolis are motivating isolation researches, identification of the possible relationship of these with its biological activity, and chemical compounds. It was used in dentistry for healing of surgical wound (or post-surgical mouth pain), tooth hypersensitivity, pulp capping and root canal treatment. Propolis has a promising goal in future medically. This research shows the application of propolis, clinically, as a natural dental medicine. Furthermore; systemic and clinical applications of these drugs may have some adverse effects like liver toxicity, drug interactions etc. Using propolis as antifungal by local application shown that it reduces the incidence of dry socket and denture stomatitis that associated with the Candida. In present study, the propolis has been used in the following manner. It is applied to the tissue surfaces of dentures, two times daily for two weeks. Propolis putty can also applied to dry socket cases after complete debridement and irrigation of it. The results showed after use propolis that the signs and symptoms including pain, redness and inflammation areas related stomatitis were gradually disappear, after 2 to 14 days the denture stomatitis is healing by using a propolis paste. Propolis putty has an effect on the fungal infection of dry socket that gradually reduced pain and inflammation until complete healing. Aim of the study, after the treatment of patients with denture stomatitis, they were subjected to examination and evaluation of the mucosa and socket, Candidal quantitative cultures and confirmation the diagnosis by three methods: Germ tube, Gram Stain, and ChromAgar media.

Abstract

This study compared the effects of 35% with 10% carbamide peroxide (CP) home used bleaching agents on enamel color change, microhardness, and surface changes in association with MI paste plus (CPP-ACPF). Forty buccal and lingual enamel samples from twenty human third molars were prepared and divided into four groups (n=10). The groups were bleached for two weeks according to different bleaching regimens as follow; G1 bleached with 10%CP, G2 bleached with 35%CP, G3 bleached with a mixture of 10%CP and MI paste plus, and G4 bleached with a mixture of 35%CP and MI paste plus. Color change was recorded with a colorimeter before and after bleaching and total color differences (ΔE*) was calculated. Vickers microhardness test was recorded for all the samples before and after treatment. One sample from each group was evaluated for surface changes by scan electron microscopy (SEM). The data were analyzed with repeated measure of variance and student's t-test at p<0.05. No significant difference in ΔE* was recorded among the four groups (p>0.05). Significant reduction in enamel microhardness was only recorded for G2 (p=0.003). SEM for G3 and G4 showed obvious mineral deposition. Similar teeth color whitening can be resulted after two weeks of bleaching with both 10%CP and 35%CP when used as recommended by the manufacturer with and without the addition of MI paste plus. Using 35%CP decreased enamel microhardness significantly, whereas MI paste plus when mixed with both bleaching agents could compensate for the microhardness reduction.

Abstract

The goals of endodontic preparation were to shape and clean the space of the root canal and remove microorganisms, affected dentin and pulp, the apical foramen and the canal curve should be protected from being transported during endodontic canal preparation. The aim of this study was to evaluate the curve straightening of curved root canals and apical transportation after preparation with four rotary systems. Forty mesial roots of the lower 1st molars teeth only the mesiobuccal canals were used, these roots were immersed into cold clear acrylic , the teeth roots divided into four groups according to rotary system used for preparation of the canals (ten roots for each group):. group I: ProTaper Next rotary system, group II: IRaCe Plus rotary system, group III: HeroShaper rotary system, group IV: ProTaper rotary system, instrumentation were done to size 30 master apical file and with copious irrigation, total amount of 10 ml of 2.5% of sodium hypochlorite (NaOCl) then rinsed the canals with distilled water 5 ml. radiograph was taken for all roots before and after instrumentation in one direction buccolingual using digital radiograph system. The degree of curve straightening of the root canal and the apical transportation were measured using Image J software and Adobe photoshop CS6 software. Statistical analysis was done and the result showed that group IV had the highest mean values in curve straightening and apical transportation, there were significant difference between group IV and all of the other groups and there were non- significant difference between group I , group II and group . All the four used rotary systems produced adequate geometry during canal preparations. However, some apical transportation in ProTaper group was seen, which might need a caution when used protaper in instrumentation of curved canal.

Abstract

ovary syndrome (PCOS) and periodontal diseases are common chronic inflammatory disorders. PCOS is a complicated condition affects overall health and causes broad spectrum changes that affect periodontal health status. Available evidence suggests that oxidative stress might comprise a link for the association between periodontal diseases and components of the metabolic syndrome. Both homocysteine (Hcy) and nitric oxide (NO) are considered to reflect the strength of oxidative stress. The aims of the study were to compare the periodontal health condition among the study groups (gingivitis, gingivitis +PCOS, chronic periodontitis (CP) and CP + PCOS group) by measuring the clinical periodontal parameters (Plaque Index (PLI), Gingival Index (GI), Bleeding on Probing (BOP), Probing Pocket Depth (PPD) and Clinical Attachment Level (CAL), and measure serum (Hcy) and (NO) and compare their levels between study groups , then correlate between these parameters with each other and with clinical periodontal parameters in order to determine the effect of PCOS on periodontal health status and levels of serum Hcy and NO.

Abstract

The lower third molar is the most teeth failed to erupt in the alveolar process and the surgical extraction of lower third molar is widely carried out in the dental clinic due to pathologic change and prophylactically purpose, the damage of the inferior dental canal can be occurred when the lower third molar located deep and its root is closely to the inferior dental canal, the aim of this study was to investigate the prevalence of the types of impacted lower third molar between male and female and to determine the radiographic relationship of the inferior dental canal to the root apices of different types of the impacted lower third molar using dental panoramic radiograph, eighty (80) panoramic radiographic images ,40 male 40 female aged (18-41) were selected from the pool of data stored in the computer of the digital panoramic machine, the teeth were divided according to the relation to the lower 7th molar (angulation), and the relation of the root apices to the inferior dental canal according to the distance of root apices from the inferior dental canal either far, close , superimposed. The result of this study showed that the mesioangular type of impaction is the most closely positioned to the inferior dental canal , and this may represent an independent risk factor for postoperative paraesthesia, the majority of patients showed the position of the inferior dental canal varies in relation to the root apices of impacted mandibular third with the majority being in adjacent position , The superimposed relation of roots apices of the mesioangular impaction in male was 32% while in female was 46% so the risk of the damage to the mandibular canal in female more than the male during the surgical extraction of lower third molar, this variation should be appreciated by the oral surgeon when undertaking surgical extraction of the impacted mandibular third molars.

Abstract

The Iraqi and the Yemeni dental literature lack documentation of keratoacanthoma (KA). It uncommonly appears at the mucocutanous junction and very rarely reported to arise in the mucous membrane. Nevertheless, it has such a chance; therefore, it is necessary to bring the attention of dental practitioners to this lesion. It is a benign epithelial tumor that frequently affects the face of old people. It usually, appears as an exophytic nodule with a central keratin plug that grows rapidly but with several poses. Clinically and microscopically KA is similar to squamous cell carcinoma (SCC) and can be occasionally misdiagnosed therefore it is important to be biopsied and carefully interpreted. This report presents two clinically unusual cases of KA.
