Background and Aim: Several methods have been suggested to measure gingival thick-ness. This study aimed to assess the reliability of visual assessment of facial gingival biotype of maxillary and mandibular teeth with or without using a periodontal probe in comparison with direct measurement. Materials and Methods: Sixty-seven healthy patients (25 women and 42 men) with a total of 100 hopele...

many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. in this study for asessing genetic diversity among bradyrhizobium japonicum isolates, two different probes (suca and topa) chosen from the chromosomal genome of bradyrhizobium strain usda 110 were designed, evaluated by dnaman software and im...

A large-scale probe has been developed for measuring the thermal conductivity of geomaterials. The large probe was designed to conduct tests on materials containing large particles, materials with high heterogeneity, and materials with high stiffness. The probe has dimensions of 680 mm length and 15.9 mm diameter and was constructed of stainless steel tubing. The probe operates on the principle...

OBJECTIVE To study the relationship of the expression of phosphorylated cyclic AMP response element-binding protein (pCREB) and early growth response protein 1 (Egr1) in the hippocampus of aged mice with retrieval of consolidated spatial memory in a water maze. METHODS Twenty-four aged mice were allocated into no training or probe test (naïve), no training but exposed to the same probe test (...

abstract statement of problem: dentin hypersensitivity is one of the most common complaints of patients after periodontal treatments which occur after tissue shrinkage. objectives: the aim of this study was to determine and compare the effectiveness of sensikin gel (10% potassium nitrate and 0.22% sodium fluoride) with sodium fluoride gel (2.7%) and fluoride varnish (5%) in reducing the dentin ...

in this study, a cylindrical bolling probe was developed and evaluated for measuring stress in soil under tire traffic. the probe consists of a silicon rubber head for sensing the soil stress, a pvc tube for transferring the liquid pressure, a digital pressure sensor and a syringe for filling the probe with water and adjusting the initial inclusion pressure. a tank with pressurized air was used...

This paper describes a method for characterizing the step response of a thermistor probe embedded in a low-conductivity solid. We define the “step response” as the dynamic response of a finite-size thermosensor instantaneously plunged into an infinite homogeneous conductive solid. The final goal of this research is to evaluate and enhance the time-dependent response of contact-type thermosensor...

This study technically assessed the WHO-621 periodontal probe made in Brazil as well as its dimensional and weight stability after sterilization. The following characteristics were measured in one hundred (100) new probes: diameter and linear area of tip sphere and beginning and ending references of its colored band by means of indirect computerized morphometric method, and weight, by means of ...

In Nigeria, one of the highest tuberculosis (TB) burdened nations, sputum smear microscopy is routinely employed for TB diagnosis at Directly Observed Treatment Short-Course (DOTS) Centers. This diagnostic algorithm does not differentiate Mycobacterium tuberculosis complex (MTC) from nontuberculous mycobacteria (NTM). Between December 2008 and January 2009, consecutive patients diagnosed with T...
