SS at transition periods to a new cycle: According to the H. P. Blavatsky's Worksand Theosophical Tradition

Everything that happens in the Universe, from the beginning of Mahamanvanthara, happens according to certain laws of the Universe. These Laws are an expression of Higher Consciousness. Everything that exists, from electron to star, is permeated by Consciousness. This Primary Reality is still beyond our perception, but sages and saints have always named it by contradicting terms. Many called it “God,” others called the Law, Heaven, the Great Architect, Evolution, Avalokiteshvara. Each person, in accordance with his character and experience, can determine his attitude towards this Consciousness, which directs everything in the manifested Universe. According to theosophical tradition and cosmogony, there is only a single Law in the Universe, “the law of harmony, perfect balance” 151, which acts as a single energy through the Logos. And during Manvantar, the Logos has its own consciousness and its own individuality, which, in turn, first manifests itself as Light, or universal consciousness, and then as individual consciousness. The Trinitarian Logos acts through the Creative Hierarchies of spiritual plans, these are the plans of the Higher Consciousness on which the Logos unfolds the Universe, “supporting it during its existence and taking it into Itself at its completion”

Laser applications in smear layer removal from posterior root canals: A comparative study

Aim: The aim of the study is to evaluate erbium laser efficiency in removing smear layer from mesial roots of mandibular first molars at different laser settings. Subjects and Methods: One hundred (100) mandibular first molars were selected. Ninety six (96) mesial roots were assigned to two experimental groups according to the laser wavelength applied: I. Er, Cr: YSGG and II. erbium-doped yttrium aluminum garnet laser system. Four samples were used as control group. Samples of each group were distributed into two subgroups (A and B), following specific irrigation protocol. Each subgroup was divided into four subcategories according to the applied power laser. Each subcategory consisted of six samples. Teeth were observed under scanning electron microscope. Statistical Analysis: Results were statistically analyzed with Kruskal-Wallis and Mann-Whitney test (SPSS statistics software). Results: No statistically significant difference was observed between experimental groups I and II. However, statistically significant difference was found among subgroups IA and IB and IIA and IIB. In every root third, groups IIA and IIB had better outcomes but it was not statistically significant. There was no statistically significant difference among subcategories of Group I (IA 1-4 and IB 1-4) and Group II (IIA 1-4 and IIB 1-4). Conclusion: Erbium laser with tested parameters did not completely remove the smear layer from the root canals. Chelating factors can contribute in the laser mechanism of smear layer removal from apical part of narrow and curved root canals. © 2022 Wolters Kluwer Medknow Publications. All rights reserved
