Mercury bioactivity Metallic mercury is the least toxic from and is absorbed primarily through the lungs rather than the GI tract or skin Mercury in the body may come from air, water, food. dental (a low amount). Or medical sources  Half life for mercury elimination from body is 55 days .- mercury toxicity is <50 µm / m3 on average per 40-hour work week. Mercury hypersensitivity is estimated as less than 1 per 100,000,000 persons Indium…

Atraumatic Restorative Treatment (ART) is a minimally invasive approach to dental cavity management and restoration. Developed as a response to the limitations of traditional drilling and filling methods, ART aims to preserve as much of the natural tooth structure as possible while effectively managing caries. The technique was pioneered in the mid-1980s by Dr. Frencken in Tanzania as a way to address the high prevalence of dental decay in a setting with …

Mass Spectrometry: Protein/Body Fluid Analysis Principle: Technology: Ionization and mass-to-charge ratio analysis Applications: Protein/body fluid analysis in dental research Sample types: Saliva, gingival crevicular fluid, blood Dental Applications: Biomarker identification: Periodontal disease markers Caries susceptibility proteins Inflammatory mediators Salivary diagnostics: Disease detection panels Drug …

MAXILLARY SECOND BICUSPID smaller in dimensions. The cusps are not as sharp as the maxillary first bicuspid and have only one root. Facial: This tooth closely resembles the maxillary first premolar but is a less defined copy of its companion to the mesial. The buccal cusp is shorter, less pointed, and more rounded than the first. Lingual: Again, this tooth resembles the first. The lingual cusp, however, is more nearly as large as the buccal cusp. P…

Transport of Carbon Dioxide A.    Dissolved in Blood Plasma (7-10%) B.    Bound to Hemoglobin (20-30%) 1.    carbaminohemoglobin - Carb Dioxide binds to an amino acid on the polypeptide chains 2.    Haldane Effect - the less oxygenated blood is, the more Carb Diox it can carry a.    tissues - as Oxygen is unloaded, affinity for Carb Dioxide increases b.    lungs…
