Thermoform Retainer (Essix / Clear Retainer)
A Thermoform Retainer, also known as an Essix Retainer or Clear Retainer, is a custom-made, transparent plastic appliance used after orthodontic treatment to maintain teeth in their corrected position. It is made by heat-molding (thermoforming) a thin plastic sheet over a dental cast of the patient’s teeth.

Topical Fluoride / Fluoride Gel
Topical Fluoride (also called Fluoride Gel) is a preventive dental agent applied directly to the tooth surface to help strengthen enamel, prevent tooth decay (dental caries), and reduce sensitivity. It is one of the most effective and widely used methods for protecting teeth in both children and adults.
Total Cholesterol Reagents
🔬 1. CHOD-PAP Method (Gold Standard)
Principle
-
Cholesterol esterase converts cholesterol esters → free cholesterol
-
Cholesterol oxidase converts cholesterol → cholest-4-en-3-one + H₂O₂
-
Peroxidase (POD) uses Hâ‚‚Oâ‚‚ to produce a colored dye
-
Common chromogens: 4-AAP, TOOS, DAOS, HDAOS
-
Absorbance: measured at 500–550 nm depending on chromogen.
What the Reagents Contain
R1 (Buffer / Chromogen)
-
Good’s buffer (e.g., PIPES, TES)
-
Phenol or TOOS/DAOS derivatives
-
Stabilizers & surfactants
-
Preservatives
R2 (Enzyme Reagent)
-
Cholesterol esterase
-
Cholesterol oxidase
-
Peroxidase
-
Additional surfactants
Tracheostomy Tube – Sizes 6.5, 7.0, 7.5, 8.0
A Tracheostomy Tube is a curved, hollow medical device inserted through a tracheostomy stoma (an opening in the neck) into the trachea (windpipe) to maintain an open airway and enable breathing, suctioning, or mechanical ventilation.
The sizes 6.5, 7.0, 7.5, and 8.0 mm refer to the internal diameter (ID) of the tube, typically used for adult patients of different anatomical builds.
Triglycerides (TG) Reagents
🔬 1. Szasz Method (Standard for GGT)
Principle
GGT catalyzes the transfer of the γ-glutamyl group from a synthetic donor substrate to an acceptor molecule.
Reaction: L-γ-glutamyl-3-carboxy-4-nitroanilide
-
Glycylglycine
→ 5-amino-2-nitrobenzoate (colored product) -
γ-glutamyl-glycylglycine
The rate of formation of 5-amino-2-nitrobenzoate is measured kinetically.
Measurement
-
Absorbance: 405–410 nm
-
Mode: Kinetic, multiple readings (rate method)
-
Proportional to: GGT activity (U/L)
