[Manual dexterity and acquisition of correct dental hygiene]
Abstract:
The aim of this study was to evaluate the relationship of normal dexterity and the ability to obtain correct dental hygiene. Manual dexterity level was determined by means of psychotechnical tests on 35 students. Plaque index was noted before oral hygiene instructions including tooth-brushing and flossing techniques according to BASS. The same index was noted 15 days after instructions. Statistical analysis of results showed no significant relationship between manual dexterity and plaque control efficiency.

Handwashing I: Introduction and Types of Equipment
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated.
Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
