Therefore, the option of increasing repair strength using new reinforcement materials is of great interest to prosthodon- tists. The purpose of this study was to assess the effects of using a special type of acrylic o-cry1 in repair instead of heat cure acrylic resins and different surface treatments on impact bond strength using Ivomet and conventional curing methods. Materials and Methods: One hundred thirty specimens of heat acrylic resins were constructed. There are 2 main groups accord- ing to curing methods (Ivomet and conventional method curing). For each group, there were 6 groups according to the surface treatments used (untreated, monomer, thiner, zirconium oxide, glass fiber and butt joint with monomer) as well as control group. Results: The study showed that the control group had a higher value of impact strength than other groups which were cured by conventional method. For Ivomet curing, the butt joint with monomer and glass fiber groups improved the impact bond strength in comparison to other groups. Conclusion: the butt joint with monomer treatment and glass fiber groups have improved the impact strength of the repaired acrylic resins when using Ivomet compared with other groups. On the other hand, the use of thiner and zirconium oxide reduced the impact bond strength when using the conventional curing method. The use of Ivomet device in curing samples improved the impact strength of acrylic repaired with O-cry1.","PeriodicalId":78326,"journal":{"name":"Iraqi Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80451640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such materials are not available in the local markets. Several additive materials, hence, must be applied to the prosthesis to match the colour of natural eye. The aim of this study was to assess the effect of adding titanium dioxide oil paints to scleral part of ocular prosthesis on its porosity. Methods: there were 20 samples in total. The first group was fabricated without addition of oil paint and considered as control. The second group was constructed from heat cured acrylic resin with addition of oil paint in a concentration of 1 ml. A surface area of 1cm 2 was limited in the center of each specimen &observed under optical microscopy and numbers of pores per area was manually determined. All values were analyzed using SPSS version 20 and comparison between 2 groups was obtained using inde- pendent t test. Results: there was an increase in the mean values of porosity following addition of oil paint. The control group presented a lower mean value of porosity compared to experimental group. however, no significant differences between control and TiO 2 group where P >0.05.

Methods: The study involved 86 patients; some of whom underwent L3MS (n=46), while the others had PAS (n=40), all procedures were performed under local anesthesia. The visual analogue scale measured pain and swelling for seven consecutive days, after surgery. Results: After L3MS, it was found that patients experienced the most intense pain the day of surgery, with facial swelling reaching a maximum on the 2nd day. In addition, the influence of age and gender on the intensity of pain and degree of swelling was found to be insignificant... Patients who underwent PAS; also reported maximum pain on the day of surgery while swelling reached maximum on the 2nd day. However, female patients reported significantly more post-operative pain than males (P<0.024). No significant differences between females and males were recorded with respect to post-operative swelling, in addition, age was found to have no effect on both pain and swelling. Conclusion: Pain and swelling after L3MS and PAS peaked on the day of surgery and the day after respectively with mild to moderate intensity, it subsided gradually to minimal levels on day 7. Short-term outcomes of L3MS and PAS with respect to degrees of pain and swelling were found to be similar, and it seems to be independent of both’ age and gender.","PeriodicalId":78326,"journal":{"name":"Iraqi Dental Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72606850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to have good oral cleaning, an optimum orthodontic force, and desirable biological response and tooth movement, the current study was hence carried out to investigate the impact of Chlorhexidine and Listerine on the surface characteristics of stainless steel wire. Materials and methods : The effect of chemicals was studied through immersing the wires in the solutions for 1.5 hour. The distilled water was considered as control. The samples consisted of 10 wire pieces in the form of U shape with dimensions of (25mm length of bridge,10mm length of arms). Such wires were cut and their straight form were used for corrosion test. Wires were then embedded in base of cold cure acrylic resin ( 3mm thickness,10mm width,65mm length). Next, The wires were connected to conductor rod. A potention state equipment was utilized for testing the samples and a Nikon digital optical microscope was used to identify the surface changes. ANOVA and LSD tests were utilized for statistical analysis. Results : the results indicated that the Listerine group presented the highest mean of corrosion resistance; on the other hand, chlorhexidine group created a greater value of mean in comparison to control group. Furthermore, highly significant differences were observed between two groups (P<0.01). Moreover, there were significant differences among all groups (P<0.01). Conclusion : The Listerine has a significant effect on the surface corrosion of stainless steel wire compared to chlorhexidine.

This study had been conducted to find out the relationship between symptoms and the causative factor(s) of the disease, so that to make successful treatment more easily reachable. Method: The study was conducted with informed consent on 124 patients (63 females and 61 males, ages ranging from 39 to 66) complaining of burning mouth syndrome visited the Oral Medicine Clinic in Dentistry College/ Muthanna University and referred by dentists to private clinic for consultation from January 2014 to November 2016. Medical and social history was taken from each patient, haematological investigations and measurement of stimulated salivary flow rate were done for all patients. Intraoral exam was done for each patient to exclude any detectable lesion. Findings were recorded and matched with symptoms for each patient. Each patient received treatment according to diagnosis of causative factor(s) and 6 months follow up was done for each patient after initiation of treatment to evaluate the outcome of treatment and to confirm the accuracy of diagnosis in case of good response to treatment for each patient. Results: Group A: no 41 subjects (33% of all groups): complained of continuous symptomatic day with asymptomatic night, examination and investigations showed that 35 of them (85.4% of group A) were complaining of chronic anxiety and menopause women, while the rest 6 were of similar symptoms but due to different causative factor(s).
