Evaluation of Antimicrobial Effectiveness of Dental Cement Materials on Growth of Different Bacterial Strains.

BACKGROUND The aim of this study was to evaluate the antimicrobial effectiveness of dental cement materials for the prevention of bacterial growth, which can cause failure of fixed cementation. MATERIAL AND METHODS We developed an agar diffusion disk test in-house to evaluate the antibacterial properties of 3 commercially available dental cement materials (Ketac, Harvard FLB, and Panavia SA Universal Dual Resin cements) compared with a negative control. The materials were tested for the inhibition against Streptococcus mutans (ATCC 10449), Streptoccocus salivarius (ATCC 25975), Enterococcus faecalis (ATCC 29212), and Lactobacilus acidophilus (ATCC 4356).

Disinfection of Infected Artificial Dental Periapical Lesions with Diode Laser: An In Vitro Study.

BACKGROUND Periapical lesions are primarily caused by infections in the root canals. The objective of this study was to assess the antibacterial effectiveness of diode laser during root canal treatment in artificial models of infected periapical lesions. MATERIAL AND METHODS One hundred twenty-two extracted premolar single-rooted teeth were inserted into methyl methacrylate artificial models of periapical lesions, and bacterial solutions of Enterococcus faecalis (ATCC 29212) and Streptococcus mitis (ATCC 49456) were then applied to the models.

Antimicrobial Effect of Orthodontic Materials on Cariogenic Bacteria Streptococcus mutans and Lactobacillus acidophilus.

BACKGROUND White spot lesions (WSLs) are a common complication after orthodontic treatment. The aim of this study was to characterize and compare the antimicrobial properties of selenium-containing vs. fluoride-containing orthodontic materials.

The Effect of Ca and Mg Concentrations and Quantity and Their Correlation with Caries Intensity in School-Age Children.

Introduction: Saliva is a watery product formed by the salivary glands and secreted in the mouth. Besides the fundamental factors, saliva with its ingredient is one of the main etiologic factors of caries presence. In the development of dental caries, the relationship between demineralization and remineralization is influenced by the presence of saliva, which facilitates the transportation of ions, oral bacteria, and fermentable carbohydrates to the exposed surfaces of teeth.

The Role and Impact of Salivary Zn Levels on Dental Caries.

Introduction: Minimal attention has been given to the role of salivary microelements, the importance they have in reducing the intensity of caries, and the effect of caries prophylaxes.

Aim: This research aimed to determine the concentration and quantity of Zn and its impact on the prevention and the reduction of the intensity of caries in schoolchildren aged 12-13 years with permanent dentition.

Methods: For this research, we analyzed the stimulated and nonstimulated full saliva of 106 schoolchildren divided into three groups by mean decayed, missing, and filled teeth (DMFT) index.
