Comparative evaluation of tooth enamel abrasion induced by different toothpastes

Tooth brushing along with a toothpaste is the most frequent and important method in managing a healthy oral hygiene. However, using such products also has its side-effects and shortcomings. Considering the large range of toothpastes available and the insufficiency of proper researches in this area in Iran, this study was designed to evaluate the abrasiveness of a toothpaste for sensitive teeth and a whitening one with two similar Iranian brands. This was an invitro experimental study. Four groups of enamel samples consisting of each 6 specimens were prepared and embedded in acrylic blocks. The initial surface profile for each specimen was calculated using a profilometer. The samples undertook the wear phase in a V8 Cross Brushing machine using toothbrushes and a toothpaste solution. The samples were then dried and the surface profile was again calculated. The variation of the first and second profilometer calculations demonstrate the amount of wear for each specimen. Data was analyzed using the SPSS program by means of One way ANOVA and Repeated Measure ANOVA tests. The amount of wear recorded for the 4 experimental groups was significantly different [p=0.039]. However, the two by two comparision tests showed that the Iranian brands did not appear to have a significant difference with their foreign counterparts [p>0.05]. The only difference was apperant between the two Iranian brand groups. According to the present study, it seems that there is no significant difference in the abrasive properties of the Iranian and foreign made toothpastes. However, similar researches considering different effects of toothpastes and especially in more clinical conditions and by utilizing different measurement methods appears to be necessary in Iran

Comparison of the use of silk sutures and cyanoacrylate tissue glue after periodontal flaps in patients with moderate periodontitis

The use of silk suturing materials and cyanoacrylate tissue glue are common in wound closure after periodontal surgeries, gingival grafts, tumor removal, etc. The aim of this study was to compare the use of silk sutures and cyanoacrylate tissue glue [EPIGLU] in wound closure after periodontal flaps in patients with moderate periodontal. This experimental study was conducted on fifteen patients [10 female, 5 male] aged 25-55 years with moderate periodontitis in need of flap surgery on both sides. After a Widman modified surgical flap, the incision lines were randomly closed with silk sutures on one side [control group] and EPIGLU on the other side [study group]. The patients were followed for 2 weeks post surgery and the two groups were compared in terms of pain, bleeding, wound healing, sensitivity and tissue compatibility. Sign and Friedman tests were used to compare the results. The use of EPIGLU showed no significant differences with silk sutures in most cases but the differences became more prevalent with time. Considering the favorable properties of EPIGLU such as improved wound healing, less bleeding, superior clinical performance, minimal chair time and patient acceptability, it is suggested as a replacement for silk sutures

[Anti-inflamnatey effect of 15 percent benzydamin mouth wash onmoderate periodontits patients]

The periodontal inflammation is one of the most common oral and dental diseases. Periodontitis is advanced periodontal bacterial infection. At present treatment of this disease is oral hygiene instructions, scaling and root planning, plaque control with different mouth washes and in some cases, periodontal surgery. In this investigation, Benzydamin was used as mouth wash which has anti pain and anesthetic properties. The purpose of this research was to study anti-inflammatory effects of using Benzydamin mouth wash 0.15 percent on moderate periodontitis. This was a clinical test study, which has been done in Isfahan University [School of Dentistry]. Sample included 80 patients, [52 female and 28 male] with an average age of 27years. Patients who had moderate periodontitis were tested and divided into 40 person group [case and control]. In both groups before performing the firt phase of treatment, index of gingival inflammation and bleeding index was determined. In case group, patients were given both oral hygience instructions and oral Bensydamin month wash. In control group only oral hygiene instructions were given to them. After one week, both case and control groups were recalled and once more indexes determined and then average was made. Acording to statistical formulas descriptive statistic and t-tests, curves and tables were made. The mean for bleeding index before clinical test were 2.01 and 1.7 and after clinical test were 1.22 and 1.27 for both case and control groups. These differences between two groups were significant. But the mean for gingival inflamation index before and after clinical test were 2.18, 2.01 and 1.87, 2.03 which in both stages. Their differences were not significant. Rsults indicate Benayamin month wash will decrease gingival bleeding and to lesser extend gingival inflamation. In control group, bleeding index was decreased slightly which can be due to oral hygiene instructions
