Effectiveness of Two Wavelengths of Diode Laser and Amorphous Calcium Phosphate-Casein Phosphopeptide Mousse in the Treatment of Dentinal Hypersensitivity: A Randomized Clinical Study.

In office methods for immediate relief of dentinal hypersensitivity (DH) has long been an area of research. This study compared the efficacy of 660 nm diode laser, 980 nm diode laser, and amorphous calcium phosphate-casein phosphopeptide (ACP-CPP) agent in the treatment of DH. A total of 39 patients with minimum three hypersensitive teeth in at least one quadrant were selected and randomly divided into three groups; Group A, B, and C patients were treated by 660 nm diode laser, 980 nm diode laser, and ACP-CPP agent, respectively.

An innovative approach for estimating energy absorption buildup factors (EABF) with HVL and TVL.

The current study proposes an empirical formula for absorption buildup factors as a function of target thickness. The present formula produces absorption buildup factors of compounds and mixtures with simple inputs of linear attenuation coefficient (μ), tenth value layer (TVL) and half value layer (HVL) of interacting target for the atomic number region 29 < Z < 92 for the energies 0.2 MeV < E < 1.

Heavy particle radioactivity of superheavy nuclei.

We investigated different decay modes such as heavy particle radioactivity (HPR), spontaneous fission (SF), alpha decay and beta-decay in superheavy (SH) region 104 ≤ Z ≤ 126. In HPR, different emissions from Zmin = 28 to maximum heavy particle (HP) emission up to Zmax = Z - 82 were considered. In the evaluation of Q-values, mass excess Weizsäcker-Skyrme 4+radial basis function (WS4+RBF) values were taken into account.

An investigation on polymers for shielding of cosmic radiation for lunar exploration.

In outer space, we find many types of radiations that are due to solar flares, radiation belt, cosmic rays, etc. We are fortunate enough to be protected from these radiations on the surface of the Earth, whereas in other celestial objects such as planets and satellites, without a protecting atmosphere, penetration of radiation that may be ionising or non-ionising is inevitable. Hence, studying radiation environment and its effect on such celestial objects is very important for establishing facilities such as satellites, payloads, vehicles and human exploration.

A clinical investigation to assess the regenerative potential of Biostite (hydroxyapatite, type-I collagen and chondroitin-sulphate) with or without Paroguide type-I collagen and chondroitin sulphate) membrane in the treatment of periodontal intrabony defects appraised with surgical re-entry and computer-assisted densitometric image analysis.

Background: The traditional treatment procedures which aimed at treating periodontal disease did not result in true periodontal regeneration. Unpredictability about osseous defect fill after periodontal flap surgery has stemmed in the research of a variety of regenerative materials. This randomized clinical trial was conducted to compare regenerative potential of Biostite bone graft material with and without Paroguide a bioresorbable membrane in the treatment of periodontal osseous defects.
