Hypertension with Tachycardia.  # In a hypertensive patient on B-blockers, an injection of Local anesthesia + Adrenaline will cause: A. Hypertension and Tachycardia B. Hypertension and Bradycardia C. Hypotension and Tachycardia D. Hypotension and Bradycardia The correct answer is B. Hypertension and Bradycardia. There are two separate drug interaction considerations with local anesthetics, the anesthetic itself and the vasoconstrictor.

Mal-aligned teeth or crooked teeth are problematic not only aesthetically but also from a health point of view. Irregularly placed teeth when present are difficult to clean and maintain hygiene, affect the speech, alters the facial profile and decreases the quality of smile and overall confidence of the person. Let's see what are the causes of having crooked teeth. 1. Heredity and Evolution During the course of evolution, the size of man's jaw has been decreasing gradually.

If any of the parents have crooked tooth, the offsprings may also inherit the same. 2. Tooth size arch length discrepancy When the jaws are smaller and they cannot accommodate all the teeth in the arch properly, the...

Gemination: An attempt at division of a single tooth before calcification, resulting in incomplete formation of two teeth. The resultant structure will have two completely or incompletely separated crowns with a single root and root canal. It is difficult to differentiate between gemination and a case in which there has been fusion between a normal tooth and a supernumerary tooth. Twinning: The division of a single tooth resulting in one normal and one supernumerary tooth. The number of teeth will be more than normal. Concrescence: A form of fusion of cementum after completion of root formation The teeth are united by cementum only. Maxillary molars are frequently involved Fusion:  Union of two normally separated tooth germs. If the union occurs before calcification, the two teeth are completely united to form a single Large tooth. If the union occurs after calcification, there is union of roots only. The tooth may have separate or fused ...
