Objectives: To measure the release of TEGDMA and BisGMA from two commercially available composite resins; Filtek Z 250 (3M ESPE, Germany), Leaddent (Leaddent, Germany) and two fissure sealants; Helioseal F (3M ESPE, Germany) Enamel Loc (Premiere Rev, USA) over 1, 3 and 7 days after polymerization with standard quartz-tungsten halogen Coltolux II (QHL) (Coltene Switzerland) and a standard blue light emitting diode Elipar Freelight 2 (3M ESPE, Germany).
Methods: 9 samples of each material were placed in disc shaped specimens in 1 mm of thickness and 10 mm in diameter (n=36). Each material was polymerized using LED for 20 s (n=12), 40 s (n=12) and halogen for 40 s (n=12), respectively.
Purpose: The effect of three different bonding strategies on the shear bond strength of a resin composite to fluorotic enamel surfaces was investigated.
Materials And Methods: Thirty-six noncarious extracted human molars with fluorosis and 36 without fluorosis were scraped clean from any remaining tissue, and then were divided into three subgroups according to the tested dentin bonding systems. The resin composite was bonded to the teeth using three different adhesive systems: Peak LC Bond with an etch-and-rinse technique (Ultradent Products), Peak LC Bond with a self-etching technique using Peak SE Primer (Ultradent Products), and Xeno V (Dentsply Caulk) using a one-bottle self-etching technique.
Objectives: The aim of this study was to investigate microhardness and compressive strength of composite resin (Tetric-Ceram, Ivoclar Vivadent), compomer (Compoglass, Ivoclar, Vivadent), and resin modified glass ionomer cement (Fuji II LC, GC Corp) polymerized using halogen light (Optilux 501, Demetron, Kerr) and LED (Bluephase C5, Ivoclar Vivadent) for different curing times.
Methods: Samples were placed in disc shaped plastic molds with uniform size of 5 mm diameter and 2 mm in thickness for surface microhardness test and placed in a diameter of 4 mm and a length of 2 mm teflon cylinders for compressive strength test. For each subgroup, 20 samples for microhardness (n=180) and 5 samples for compressive strength were prepared (n=45).

Statement Of The Problem: Many regions in the world do not have electricity, water, or access to dental facilities that allows the treatment of caries with dental handpieces and rotary burs. For restorative techniques used in these regions, an antibacterial self-adherent glass ionomer material would contribute considerably.
Purpose: This study aimed to test if chlorhexidine diacetate (Fluka BioChemika, Buchs, Switzerland)- or chlorhexidine digluconate (Sigma-Aldrich, Steinheim, Germany)-added ChemFil Superior glass ionomer cement (Dentsply DeTrey, Konstanz, Germany) had any long-term antibacterial effect against certain oral bacteria and to test the new formulation's physical properties.
In this study, we investigated the oral status of children suffering from end-stage renal disease (ESRD) with the aim of determining the causes of low caries prevalence in this population (using the CRT bacteria and buffer test), and compared results with a control group (n=38). In the study group, there were 38 children (aged 4-17 years) who were being treated in pediatric nephrology units at three different hospitals in Izmir, Turkey. The study and control groups did not significantly differ in daily tooth brushing frequency and periodic dental check-up frequency.

The term infraclusion is usually used to define mandibular primary teeth in posterior region that remain below the occlusion level. The degree of infraclusion depends on some factors like deviation below the occlusal plane, and infraclusion of tooth in the alveolar bone. Deficient eruptive force, disturbed metabolism of the periodontal ligament, trauma, local inflammation, deficient local vertical bone growth, disturbance in interaction between normal resorption and hard tissue repair, ankylosis and hereditary components have been given as etiological factors.
