Evaluation of community periodontal index of treatment needs in pregnant and non pregnant women

Based on the latest researches it is concluded that periodontal disease is an important risk factor, leading to preterm delivery low birth weight babies and the effects of socioeconomic status on periodontal condition. The aim of this study, evaluation of periodontal condition of pregnant and non-pregnant women based on CPITN index and relation between the demographic and clinical variables. A cross-sectional descriptive study was carried out among 540 pregnant and non-pregnant women. Data collection was carried out with a questionnaire with demographic and clinical variables. Examinations were performed with WHO probes and dental mirrors. Data were analyzed by the means on Chi-square T-test and Anova. SPSS Software was used. The results of study showed that 66.7% pregnant women had periodontal disease and 92% pregnant women in third trimester had periodontal disease. There was a significant relation between CPITN and gestational age, education level, economic level and frequency of tooth brushing. The results of this study showed that pregnant women had higher CPITN than non pregnant women, then it might be suggested that simple preventive oral hygiene program help to maintain healthy periodontium during pregnancy

Comparison of the effects of two immediate dentin sealing procedures on shear bond strength of resin cements to dentin

Cementation of indirect restorations with resin cements, does not always provide better bonding performance to dentin when compared with direct dentin bonding systems. Immediate dentin sealing was introduced to overcome this problem with some successful reports. The aim of this study was to compare the effect of immediate dentin sealing on shear bond strength of resin to dentin. In this study, 66 human third molars were randomly divided in three equal groups: 1- Bonding composite blocks with dual cured RelyX ARC cement to dentin without pretreatment. 2- Bonding composite blocks with dual cured Rely XARC cement to immediately sealed dentin with single bond and 3- Bonding composite blocks with dual cured Rely X ARC cement to immediately sealed dentin with single bond and a flowable composite. Shear bond strengths were measured with a universal testing machine. Data were analysed by one-way ANOVA and Tukey statistical tests. Means and standard deviations of tensile bond strengths were as follows: groupl:8.55 +/- 3.18, group 2: 6.67 +/- 2.21 and group 3: 14.07 +/- 5.02. The differences in shear bond strength between groups were different significantly only when group 3 was compared with groups 1 and 2 [P= 0.000]. Immediate dentin sealing with dentin bonding had no effect on bond strength. Use of flowable composite in combination with single bond improved bond strength

[Relationship between chronic periodontitis and plasmatic level of total cholesterol, triglycerides, LDL and HDL cholesterol in patients referring to Ahvaz dental school in 1386-87]

Hyperlipidemia is a major risk factor for cardiovascular disease. In recent years some evidence have been presented on the association of periodontal and cardiovascular disease. Acute systemic or local chronic infections seem to induce changes in the plasmatic concentration of cytokines and hormones, which determine changes in the lipid metabolism. The aim of this study was the evaluation of association between chronic periodontitis and plasma lipid level. The plasma lipids levels of were measured in 90 subjects. The patients were divided into two age- and sex- matched groups: a test group, composed of 45 individuals with chronic periodontal diseases ranging from moderate to severe, with at least two periodontal pocket >/= 5[mm]; and a control group, composed of 45 periodontally healthy individuals or with gingivitis. Individuals with diabetes, hypertension, with history of myocardial infarction or cancer, or those who used diuretics, corticosteroids, anabolic steroids, and those who had received periodontal treatment in the last six months and/or took cholesterol reduction medicine in the last two months before the beginning of this study were not included in the study. Variables related to high cholesterol levels, including age, sex and, body mass index, were evaluated. Total cholesterol [CHOL] and triglycerides [TG] were significantly higher in case group compared with control group [P<0.001]. HDL and LDL cholesterols were higher in cases but didn't have any significant differences with controls. The frequency of persons with pathologic value of TG and CHOL were significantly higher in cases compared with control group. This study showed that hyperlipidemia may be associated with periodontitis in medically healthy people but we can not conclude that whether periodontitis causes an increase in levels of serum lipids or whether hyperlipidemia is a risk factor for periodontitis

[Coronally advanced flap with connective tissue graft with or without epithelial collar in the treatment of localized gingival recession and increasing width of Keratinized gingiva a comparative study]

Regarding to the prevalence of gingival recession, esthetic and sensitivity problems of denuded roots, a variety of surgical techniques have been used to cover recession type defects. This sequential matched randomized double blind clinical trial was designed to compare the clinical outcome following treatment of localized gingival recession by subepithelial connective tissue graft [SeCTG] with and without epithelial collar. Nine consecutively patients with bilateral 24 Miller class I gingival recession in non - molar teeth, were participated in this study. The surgical areas were randomly selected as split mouth and were treated by SeCTG with or without epithelial collar. Clinical measurements including recession height [RH], recession width [RW], probing depth [PD], keratinized gingiva [KG], and clinical attachment level [CAL] were measured at baseline and 3 months post operatively by means of Williams probe, caliper and stent. Changes in these clinical parameters were calculated in and between groups and analyzed statistically with paired T test. Both treatments resulted in a significant decrease in RH [1.88 +/- 0.93 mm, P<0.000 in SeCTG with collar epithelium; 1.54 +/- 1.11 mm, P<0001 in SeCTG without collar epithelium] and RW [1.62 +/- 1.38 mm, P<0.002 in SeCTG with collar epithelium; 1.22 +/- 1.62 mm, P<0.024 in SeCTG without collar epithelium]. The mean changes in RH, RW, KG, CAL in each group to baseline were significant. However, the amount of these variables were not significant between the two groups. The subepithelial connective tissue graft with epithelial collar offers a more convenient approach for handling and suturing as a root coverage procedure and increasing width of keratinized gingiva in Miller class I recession defects specially in fixed and removable partial dentures for abutment teeth
