INTRODUCTION It is imperative that the endodontic surgeon be knowledgeable of the anatomic dimensions of the surgical site. If cone-beam computed tomography is not available because of location/cost, it is prudent for the clinician to consult a knowledge base for the surgical site. An understanding of the root thickness of maxillary premolars and molars at the preferred level for root resection...

Abstract Background the position and angulation of mandibular third molars have both been found to influence angle condylar fractures. Objective: To identify whether there is an association between depth molar impaction relative risk fracture condyle. Method Four-hundred eighty-two panoramic dental radiographs were assessed for period from January 2012 June 2020. The study variables included pr...

The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...

INTRODUCTION We evaluated the relative position of the greater palatine foramen (GPF) for precise injection of local anaesthetics, for optimal pain control in maxillofacial and dental surgeries. METHODS The study was conducted in 132 adult dried unsexed skulls of the west coast region of Southern India. All the skulls studied were normal with fully erupted third molars and free from any patho...

[1] Side-scan sonar, submersible observations and sampling of lava flows from the East Pacific Rise, 17 –19 S constrain the character and variability of submarine volcanic eruptions along mid-ocean ridges. Nine separate lava sequences were mapped using relative age and lithological contrasts among recovered samples. Axial lengths activated during eruptive episodes range from 1 to >18 km; indivi...

In the past few years there have been significant advances in the identification of putative stem cells also referred to as "mesenchymal stem cells" (MSC) in dental tissues including the dental pulp. It is thought that MSC in dental pulp share certain similarities with MSC isolated from other tissues. However, cells in dental pulp are still poorly characterized. This study focused on the charac...

• “Dual use research of concern,” or DURC, denotes beneficial life sciences research whose results could be misused by those wishing to cause harm. • Dual use was largely ignored until a couple of years ago, when debate erupted over the publication of manuscripts describing enhanced transmissibility of H5N1 highly pathogenic avian influenza. • Dual use has not served its intended purpose of cle...

densities and excess molar volume of the binary and ternary mixtures formed by nbutylacetate+ 1-butanol + 1,2-butanediol were measured at (298.15, 303.15, and 308.15) k forthe liquid region and at ambient pressure (81.5) k pa , for the whole composition range. theexcess molar volumes,vme and excess partial molar volume vie ,were calculated fromexperimental densities.the excess molar volumes are...

The influence of increasing the SiO2/K2O molar ratio on the electrochemical action of a waterborne potassium silicate zinc-rich coating was investigated by means of electrochemical impedance spectroscopy (EIS) and corrosion potential (Ecorr) measurements. The EIS results showed that increasing the SiO2/K2O molar ratio in the range of 3.135 to 5 by the addition of nano-SiO2 to the resins improve...
