Clinical evaluation of composite restorations in Er:YAG laser-prepared cavities re-wetting with chlorhexidine

The objective of this study was to evaluate longitudinally the composite restorations, performed in cavities prepared by Er:YAG or conventional bur, and dentin re-wetting with water or chlorhexidine. Materials and methodsTwenty individuals with four active caries with cavitation reaching the dentin located on the occlusal surface of molars counterparts are selected. The teeth of each individual were randomly assigned into four groups: (I) Er:YAG laser (260 mJ/4 Hz) re-wetting with chlorhexidine, (II) Er:YAG laser (260 mJ/4 Hz) re-wetting with deionized water, (III) conventional method re-wetting with chlorhexidine, and (IV) conventional method re-wetting with deionized water. The teeth were isolated, prepared cavities, phosphoric acid etching, and re-wetting according to previously assigned method. Restoration was performed employing the Single Bond 2 and Z350XT resin. Clinical follow-up was held after the polishing of the restoration (baseline) and 6 and 12 months of the making of the restoration using the modified USPHS criteria. The restorations were qualitatively analyzed by means of photographs. In the evaluation period, replicas of the restorations were analyzed by SEM. Data were analyzed by statistics using chi-square test (p

ConclusionsPerampanel is effective against various types of seizures, including ES, in pediatric patients with refractory epilepsy. Furthermore, PER has good tolerability when the dose is adjusted based on serum concentrations. The PER CD ratio was lower in pediatric patients than in adolescents and adults; therefore, clinicians must consider the CD ratio when treating children with PER.

In this study, a review of the existing literature on the individualization of dosing based on PK guidance was performed. In total, 79 articles were included. The methods to individualize dosing were divided into 3 categories: (1) methods using clinical parameters, (2) empirical individual PK-guided methods, and (3) maximum a posteriori (MAP) Bayesian estimation methods. The clinical parameter mainly used to individualize dosing is bleeding phenotype. Dosing based on bleeding phenotype may decrease clotting factor consumption. However, with this method, it is not possible to individualize on-demand dosing during bleeding e...

The dominant wear mechanism of the sample is oxidation wear and adhesive wear as the temperature increased from 300°C-500°C. The wear mechanism of the sample changed from abrasive wear to fatigue wear as the applied load increased from 15N to 95N. The improvement in the high-temperature wear proper...

Because of the difference between the sides at an interface, they have been used in various practical applications such as unidirectional liquid transportation. However, newly developed Janus superwettable membranes are still highly desired and challenging, considering their conventional time-consuming preparation, oil-fouling contamination, and susceptible...
