ASSESSMENT OF DMFT INDEXES, SALIVARY FLOW RATE, PH, AND DETECTIONS OF S.MUTANS SALIVARY LEVELS BY A QUANTITATIVE REAL-TIME PCR IN POLYCYSTIC OVARY SYNDROME

Objectives: PCOS is an endocrine disorder that is common in women. However, PCOS effects on oral and dental health have not been stated clearly. The aim of this study is to examine the effects of Polycystic Ovary Syndrome (PCOS), which is common in women of reproductive age, on saliva and dental tissues in these women. Materials and Methods: One-hundred individuals who were / were not diagnosed with PCOS and insulin resistance were included in this study (n=100). Subsequently, individuals, with PCOS and insulin resistance (PCOSID +), with PCOS and non-insulin resistance (PCOSID-), without PCOS and insulin resistance (ControlID +) and without PCOS and non-insulin resistance (ControlID-) were divided into 4 groups (n=25). DMFT (Decayed, Missing, Filled Teeth) index was used for dental health evaluation, while pH meter was used for saliva pH measurement. Also, Streptococcus Mutans (S. Mutans) numbers were analyzed by the real-time Polymerase Chain Reaction (PCR) method. In statistical analysis

Effects of agmatine sulphate on facial nerve injuries

PubMedID: 28122652Objective: To evaluate the effect of agmatine sulphate on facial nerve regeneration after facial nerve injury using electron and light microscopy. Methods: The study was performed on 30 male Wistar albino rats split into: a control group, a sham-treated group, a study control group, an anastomosis group, and an anastomosis plus agmatine sulphate treatment group. The mandibular branch of the facial nerve was dissected, and a piece was removed for histological and electron microscopic examination. Results: Regeneration was better in the anastomosis group than in the study control group. However, the best regeneration findings were seen in the agmatine sulphate treatment group. There was a significant difference between the agmatine group and the others in terms of median axon numbers (p < 0.004) and diameters (p < 0.004). Conclusion: Agmatine sulphate treatment with anastomosis in traumatic facial paralysis may enhance nerve regeneration. Copyright © JLO (1984) Limited 2017

Micro‐computed tomography analysis of enamel structure after different bleaching treatments

The aim of this investigation is to assess effect of three different bleaching techniques on structural integrity, mineral density and volume of enamel via micro-computed tomography (micro-CT) and examine color changes by CIELAB and CIEDE2000 formulas. Twenty-four upper premolar teeth were randomly separated into three different groups (n = 8) (group 1, 35% hydrogen peroxide (HP) gel with Er,Cr:YSGG laser activation; group 2, 35% HP gel with diode laser activation; group 3, 35% HP gel with chemically activation). High-resolution micro-CT system (Bruker Skyscan 1275, Kontich, Belgium) was carried out to scan samples. Each tooth was scanned twice before-after application of bleaching with same scanning parameters. Structural thickness, structural separation, fragmentation index, mineral density, and mineral volume of enamel were calculated for each region of interest (ROI). Color changes were measured with spectrophotometer and calculated with CIELAB and CIEDE2000 formulas. Data analysis was made with one-way ANOVA with post-hoc LSD. Micro-CT analysis indicated that statistically significant differences were found in structural thickness, and separation, mineral density, and mineral volume of enamel for different ROIs before and after whitening for whole groups (P .05). All bleaching applications exhibited similar efficiency on the enamel surface. Nevertheless, bleaching process with Er,Cr:YSGG laser had less negative effects on enamel as it showed less change in enamel compared to other bleaching treatments. Micro-CT analysis of histomorphometric parameters can be useful for further mineralization studies of dental hard tissues
