Abstract

Background: Calcium Hydroxide preparations are used extensively in dentistry, and one of these aspects is treatment of root perforations. The purpose of this in vitro study was to compare the sealing ability of a prisma (visible light cure dycal), amalgam with varnish and chemical cure dycal are used to repair lateral root perforations. Materials and Methods: Thirty extracted human maxillary anterior teeth were used; each tooth was sectioned longitudinally into facial and palatal halves .The perforations were made into each half tooth at the cervical third of the root. The samples were divided into three groups; group I was repaired with prisma, group II repaired with chemically cured dycal and group III with varnish and amalgam .The teeth halves were placed in methylene blue dye for one week period then linear dye penetration was measured from where the repair materials were made. Results: The results showed that a prisma (visible light cure dycal) demonstrated less dye penetration than other groups, the difference was statistically significant (p<0.01) from other groups, non significant differences (p>0.05) were present between amalgam with varnish and the chemically cured dycal. Conclusion: Calcium Hydroxide including the visible light cured and the chemically cured, and the amalgam with varnish, each possess a therapeutic potential for treating known and undetected root perforations. Percentage of leakage was more in amalgam with varnish group than prisma and Kerr Dycal

Abstract

Background: The solubility of the root canal sealers is undesirable, because the process of dissolution may result in gaps and voids along the sealer-dentine or sealer-gutta percha interface. The aim of this study was to assess the solubility of zinc oxide based sealer (Endofil) in normal saline solution at different time intervals. Materials and methods: Fifty standardized plastic ring moulds were constructed and filled with Endofil sealer. The specimens were allowed to dry for 24h then weighed to the nearest 0.0001g .The samples were divided randomly into 5 groups and immersed in normal saline solution for 1,7,14,28 and 56 days. The samples were removed from the solution after completing the specified immersion period and allowed to dry for 24h. Then they were weighed, the percentage weight loss was then determined. Results: The percentage weight loss was less that 3% for immersion periods not exceeding 14 days and increased up to 5.4% for the 56 days. The statistical analysis of the results revealed a non significant difference between 1 and 7 days immersion time groups, while the differences between other groups were statistically significant. Conclusion: Under the conditions of the present study, the Endofil sealer met the International Standard ISO requirement for at least 14 days. The solubility rate of the sealer increased gradually from the first day till the 56 th days, but it remained within the acceptable limits for only 14 days.

Abstract

Background: It has been recommended that all materials returning from the laboratory be disinfected before placement in the patient’s mouth. Various adverse reactions have been reported when using disinfectant solutions with impression materials. Therefore, disinfection of dental cast may be effective in preventing cross infection. This study was carried out to evaluate the effect of storage time on the antimicrobial activity of chlorhexidine, sodium hypochlorite, and madacide-1 solutions and to test the effect of spray, immersion and incorporation techniques on their activities. Materials and Methods: Stone specimens were prepared in cylindrical blocks, under aseptic conditions, containing the three tested solutions applied by spray, immersion and incorporation methods. These specimens were stored for (1½h, 1 day, 3days, 7days, and 10days) and then tested by using disk-diffusion plate method to estimate the release of disinfectant solutions against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa,and Candida albicans. The zones of inhibition were measured with a ruler (in mm) after incubation, which was for 24h at 37°C aerobically. Results: The results showed that all microorganisms were sensitive to chlorhexidine and sodium hypochlorite while E.coli and P. aeruginosa were resistant to madacide. Also it was shown that chlorhexidine was more effective than madacide and sodium hypochlorite as a long acting disinfectant while sodium hypochlorite was the most effective as a short acting one. Conclusion: Immersion method had more inhibitory effect than the other methods representing (60 %) of all the tested specimens followed by incorporation method (25%) and the least percentage for spray method (15%).

Abstract

Background: Gingival recession may be due to faulty dental treatment. The aim of this study was to investigate the distribution of fixed partial dentures according to age, sex, location and type of material used in construction and discovers the influence of fixed partial denture characteristics (quality, duration, number of abutments and pontics) on frequency of gingival recession. Materials and Methods: A total of 160 patients were selected from patients attending for dental examination at college of dentistry, University of Baghdad. The subjects had cast or ceramic fixed partial denture or dentures for at least 3 years. The distributions of restoration according to age, sex, location and type of material were investigated. Number of abutments and pontics, quality and duration of restoration since worn in relation to gingival recession were evaluated. Results: Females asked more for fixed partial dentures in younger age group than males, and in upper anterior region more than other regions. The percentage of cast fixed partial denture was more than ceramic type. A higher percentage of patients had gingival recession related to restoration with poor marginal integrity and longer period since worn. A high significant difference was found between lengths of fixed partial denture and absence of gingival recession and low significant differences between quality of restoration and presence of gingival recession. Conclusion: The study concluded that fixed partial denture characteristics (quality, duration, number of abutments and pontics) had significant and high significant effects on frequency of gingival recession

Abstract

Background: The image shift can be measured from a combination of bite-wing and panoramic radiographs, so the aim of this study was measuring the relative image shift of intracoronal pins viewed on bite-wing and panoramic radiographs by using computer. Material and methods: Sixteen pins were placed in the dentin of three molars and one premolar on the left side of a dried mandible. Panoramic and bitewing radiographs were obtained. Results: Measurements of the image of pins on the radiographs were obtained by using special computer software and these measurements were compared with measurements on the mandible. Conclusion: The bite-wing radiograph shows little distortion of the relative distances between pins. In panoramic radiograph magnification and parallax shift of the pin images were obtained. The horizontal magnification of interpin images between pins placed mesially and distally was greatest at the third and least at the first molar. For diagonally related pins in a tooth the images showed magnification and parallax shift so that the relative distance between pins placed mesiobuccally and distolingually increased from premolar to third molar, where as distobuccally and mesiolingually placed pins showed reverse trend.

Abstract

Background: Endodontically treated teeth are restored by different types of posts. The study is to evaluate the stress distribution in endodontically treated teeth restored with prefabricated post: parallel (with different thread numbers and different materials) and tapered (with different coronal diameter and different materials). Materials and methods: The models are two-dimensional bucco-lingual section of maxillary central incisor with its supporting structure restored with parallel and tapered prefabricated post mad of two types of material, composite core and ceramic crown. A 100N force applied separately in three directions vertical, oblique and horizontal. Results: the maximum equivalent Von Mises stresses of all models subjected to vertical load are located within post material, while with oblique and horizontal loads are located at post surface on the labial side. Conclusion: Load directions and post materials have much greater effect than post designs on the stress distribution. The thickness of the dentin wall is directly proportional to the ability of the tooth to withstand the occlusal loads

Abstract

Background: Water sorption may affect composite resin materials by reducing their mechanical properties and wear resistance .The aim of this study is to measure the water sorption of five different composite resin materials, for different time intervals. Materials and methods: A stainless steel mold of 4 mm width, 8 mm length and 4 mm depth was constructed to form composite blocks. Seven blocks were made of each test resin composite material. All specimens were placed in a silica-gel desiccator for 48 hours. The samples were then weighed thrice using calibrated electronic microbalance, the average reading was recorded to the nearest 0.0001g. The specimens were kept in individual containers in deionized distilled water at 37 ºC.All specimens were periodically weighed. The weight measurements were taken at 2, 8, 14, 28,42,56,70,100,150 and 240 days intervals. Results: The statistical analysis of the results showed that all composite resin specimens continued to gain weight for a period of 28 days. After that period, the weight gain continued, although at a reduced rate. The changes after the 28 days period were small for the Herculite XRV, Tetric ceram and Tetric composite resins, and greater for the Filtek P60 and Composan LCM composite resins. Conclusion: In this study water absorption increased steadily for all materials. The percentage weight change showed a tendency to increase with the time of water storage. This study concludes that over a period of 8 months, the differences in water sorption capacity of the five composite resin materials are related to the differences in the amount of filler loading in the composite resin matrix. With one exception, the composite resin materials with the largest quantity of fillers had the least water sorption capacity after eight months of storage in water

Abstract

Background: Extending the head length of carbide fissure bur is one of the major trends in bur design. The Aim of study was to evaluate the effectiveness of one of the major trends in bur design which is the extended head length carbide fissure bur, in cutting dentin. Materials and methods: The cutting of extended head length (EHL) and non extended head length (NEHL) carbide fissure burs were evaluated on dentin specimens mounted in acrylic blocks. The specimens were divided into two groups: Group I Cutting performed with NEHL carbide fissure bur (10 burs), Group II Cutting performed with EHL carbide fissure bur (10 burs). Ten cuts were performed with each bur and a total of 200 cutting rates or CRs (mm/sec) were recorded. The CRs were statistically analyzed using analysis of variance (ANOVA) test, least significant difference (LSD) test, and student t-test. Results: A significant difference (P< 0.5) appeared between CRs of group I after cut 7 and in group II after cut 2. Conclusion: Although, extending the head length of carbide fissure bur enhances it's cutting effectiveness, but such a bur is readily dulled during cutting procedure

Abstract

Background: Atopic dermatitis is a chronic inflammatory disease that causes eczema, rashes, and itching. It is most common in younger people & adolescence. Recurrent relapses are a characteristic feature of atopic eczema. Anti-inflammatory therapy of exacerbations is aimed to control effectively disease activity and permit a return to basic dermatological therapy as soon as possible. Oxidative stress & inflammatory responses are thought to be responsible for the pathogenesis of atopic dermatitis. Silymarin is a polyphenolic flavonoid derived from the seed of milk thistle (Silybum marianum (L.) Gaertner) that has anti-inflammatory, antioxidant and cytoprotective effect. The aim of this study was to evaluate the anti-inflammatory effect of topical preparation of silymarin in atopic dermatitis. Patients & method: Forty-three patients with atopic dermatitis (26 female, 14 male, 3 - 34 years old) were participated in the single blind, placebo controlled, 8-week trial. Of these, 10 patients were treated with 0.05 %, 10 patients were treated with 0.1 %, 10 patients were treated with 0.2 % topical preparation of silymarin, twice daily. The other 10 patients were received placebo twice daily. Results: There was a statistically significant improvement. A statically significant was seen in mean total body surface area involvement over time. Mean total body surface area was 25.675% at baseline & decreased to 1% at 2-4 week. Silymarin ointment was proven to act rapidly, to be highly effective, excellent improvements in pruritis, erythema, & skin irritation were noted in the patients who received 0.1 % & 0.2 % silymarin ointment topical treatment in comparison with the control group.

Abstract

Background: One stage immediate loading to implants offers some clinical advantages. The purpose of this study was to evaluate the concept of one-stage immediate loading implant (screw type) in comparison to non-loading group. Materials and Methods: One stage dental implant (Denti Dental Implant System), Hungary, 10mm in length, and of 4-4.5mm in diameter, was used. Five adult dogs of 15-22 Kg body weight were selected in the current study. Extraction of left fourth premolar and first molar was done, and the region was left to heal for about 2 months. Twenty implants were installed, ten implants of (4-4.5mm in diameter) were inserted in the left posterior region of the lower jaw which was loaded by Nickel Chrome crown which is considered as (study group), and ten implants of (4- 4.5mm in diameter), without crowns were inserted anteriorly to the loaded groups and considered as (control group). Results: The current study shows that one of the immediate loaded implant of 4mm in diameter lacked primary stability, which exfoliated later on. There were significant differences at level of loading, diameter and their interaction. Analysis of variance revealed that the smaller diameter implants were significantly higher value of mobility than larger one. The study shows a high incidence of successful rate of the immediate loaded implants of 4.5mm, similar to the non-loaded group, while low incidence of successful rate of loaded implants with 4mm in diameter in compare to the non-loaded group. Conclusions: The study reported that immediate loading of freestanding implants can achieved osseointegration by using screw shaped implant with large diameter (4.5mm) similar to the non-loaded type. The larger implant diameter associated with higher successful rate and less bone loses when compared with smaller diameter in both groups
