Süpernümerer Dişlerin Bilgisayarli Tomografi ile Değerlendirilmesi: Vaka Raporu

Süpernümerer dişler, diş arkında fazladan yer alan dişlerdir. Bu dişlerin çoğu maksiller anterior bölgede lokalize olmaktadır. Tek veya çok sayıda, unilateral veya bilateral olarak, sürmüş veya gömülü, bir veya her iki çenede birden oluşabilirler. Radyografiler süpernümerer dişlerin hem lokalizasyonlarının belirlenmesinde hem de sınıflandırılmalarında önemli bir rol oynamaktadırlar. Bilgisayarlı tomografi süpernümerer dişler ve daimi dişin kökleri arasındaki ilişkileri 3 boyutlu olarak doğru bir şekilde göstermektedir. Bu vaka raporunda maksiller daimi santral keser dişlerin palatinalinde lokalize olmuş süpernümerer dişlerin kök ilişkilerinin değerlendirilmesinde bilgisayarlı tomografinin önemi tartışılmıştır

Sub-ablative Er,Cr:YSGG laser irradiation under all-ceramic restorations: effects on demineralization and shear bond strength

WOS: 000419602500006PubMed: 28920187This study evaluated the caries resistant effects of sub-ablative Er,Cr:YSGG laser irradiation alone and combined with fluoride in comparison with fluoride application alone on enamel prepared for veneer restorations. And also, evaluated these treatments' effects on the shear bond strength of all-ceramic veneer restorations. One hundred and thirty-five human maxillary central teeth were assigned to groups of 1a-control, 1b-laser treated, 1c-fluoride treated, 1d-laser + fluoride treated for shear bond testing and to groups of 2a-positive control(non-demineralised), 2b-laser treated, 2c-fluoride treated, 2d-laser + fluoride treated, 2e-negative control (demineralised) for microhardness testing (n = 15, N = 135). Demineralisation solutions of microhardness measurements were used for the ICP-OES elemental analysis. The parameters for laser irradiation were as follows: power output, 0.25 W; total energy density, 62.5 J/cm(2) and energy density per pulse, 4.48 J/cm(2) with an irradiation time of 20 s and with no water cooling. Five percent NaF varnish was used as fluoride preparate. ANOVA and Tukey HSD tests were performed (alpha = 5%). Surface treatments showed no significant effects on shear bond strength values (p = 0.579). However, significant differences were found in microhardness measurements and in elemental analysis of Ca and P amounts (p < 0.01). Surface-treated groups showed significantly high VNH values and significantly low ICP-OES values when compared with non-treated (-control) group while there were no significance among surface-treated groups regarding VHN and ICP-OES values. Sub-ablative Er,Cr:YSGG treatment alone or combined with fluoride is as an effective method as at least fluoride alone for preventing the prepared enamel to demineralization with no negative effect on shear bond strength

ERTURK AVUNDUK, AYSE TUGBA/0000-0002-7879-8150WOS: 000481788100019PubMed: 31199544The purpose of this study was to comparatively evaluate the effects of different caries removal methods on microleakage success of class V adhesive restorations by means of light microscopy (stereomicroscope) and scanning electron microscopy (SEM) observations. Sixty-four human teeth with class V caries that measured with DIAGNOdent were used. The samples were divided into four groups (n = 16) randomly according to caries removing methods of conventional method, Carisolv, Papacarie, and Er,Cr:YSGG laser system. The self-etch Clearfil SE Bond and Clearfil Majesty Es-II were used as restoration materials. After thermal cycles of 2,000 (5 and 55 degrees C) samples were immersed in a 50% wt/wt AgNO3. Samples were finally imaged and scored under light microscopy and SEM, respectively. The data were statistically analyzed using Kruskal-Wallis H, pairwise comparison and Wilcoxon's T tests at 5% significance level (p < .05). Statistical analysis demonstrated that there was no significant difference between microleakage scores in dentin regions but there were significant difference between the Papacarie and Er,Cr:YSGGlaser in terms of leakage scores in enamel sites. No statistically significant difference in leakage scores emerged between light microscopy and SEM

The effect of temperature change on fluoride uptake from a mouthrinse by enamel specimens

Objective: The aim of this study was to examine the effect of temperature on fluoride uptake by enamel specimens from a 0.05% NaF-fluoridated mouthrinse (Oral-B Advantage; Oral-B Laboratories, Newbridge, UK). Methods: Enamel specimens were prepared from extracted human maxillary central incisors. A fluoride-specific ion electrode was used to measure the uptake from a 2 ppm fluoride solution containing 50.0 mL of distilled water, total ion strength adjustment buffer, and fluoridated rinse at 3 different temperatures (room temperature, 25°C; human body temperature, 37°C; hyper-fever temperature, 43°C). One-way analysis of variance and least significant difference were used to assess intragroup and intergroup differences (P<.05). Results: The study found that both the amount and the rate of fluoride uptake increased significantly with increase in temperature. This effect was particularly noticeable at 43°C. Conclusions: The temperature of the NaF mouthrinse may easily and safely be increased beyond room temperature by placing a conta ner of the NaF mouthrinse in a bowl of hot water, allowing greater fluoride penetration into the enamel from the mouthrinse when used at home as a routine prophylactic agent

ERTURK AVUNDUK, AYSE TUGBA/0000-0002-7879-8150WOS: 000425884700021Objective: To evaluate the place of chemo-mechanical caries removal (CMCR) methods within the scope of undergraduate education of two different dental faculties which located in close geography but with different socio-economic characteristics. Material and Methods: In this cross-sectional, descriptive study totally 130 participants (Ankara: n = 78 and Kinkkale: n = 52) were evaluated. A survey which consisting of 14 questions were conducted by face to face. Data was analyzed using the SPSS software. Frequency distributions and the Chi-Square test were applied. Results: 66.9% of the participants reported that they had knowledge about the chemomechanical caries removal method. 60% had knowledge about the mechanism of CMCR. Thirty-six point two percent of the participants from Ankara stated that they had knowledge about the CMCR mechanism and 40% did not know about any of the methods of CMCR. 52.8% of the respondents indicated that they should be minimally invasive in choosing the CMCR method. The most important reason for not choosing the CMCR method was inadequate method (32%) and takes too much time (32%). Conclusion: Significant differences were found between the students of the two cities regarding the awareness of the CMCR method. In order to overcome this disparity, the curriculum place of the CMCR method needs to be determined precisely and clearly

Colak, Hakan/0000-0001-8262-0913; Hamidi, Mehmet Mustafa/0000-0003-3461-7925WOS: 000365431800003PubMed: 25529222Purpose: Dental fluorosis is an enamel dysplasia that can cause serious aesthetic and psychological problems. An examination of the literature shows that the microabrasion method is the most effective way to treat fluorosis. This study aimed to produce a prototype microabrasion paste for the treatment of fluorosis stains and to examine the effects of the paste on tooth structure and color in vitro. Material and Methods: Forty extracted upper incisor teeth were used in this study. The teeth were divided into four treatment groups: a prototype microabrasion paste group (N = 10), an Opalustre paste group (N = 10), a 37% phosphoric acid gel group (N = 10), and a distilled water (control) group (N = 10). Following treatment, all specimens in each of the four groups were examined by scanning electron microscopy for changes in their surface enamel. Changes in tooth color changes of the 1st and 2nd groups were measured before and after treatment by a VITA Easyshade Advance spectrophotometer. Results: In scanning electron microscopy evaluations, significant differences were not observed between the 1st and 2nd groups. Differences in three color-measuring coordinates between the 1st and 2nd were also not statistically significant (p > 0.05). Conclusions: The study demonstrated that the prototype paste is a viable treatment option for dental fluorosis. CLINICAL SIGNIFICANCE The findings in this study demonstrated that the tested prototype microabrasion paste is extremely harmless, minimally invasive agent, and able to improve the color, shine and chrome values of the teeth
