Being a Dentist we are bit different from other health professionals. We treat the patients by working actively inside there mouth. We need superior manual dexterity then most of the other health professionals.
Consider average mouth opening of a person- Not more then four fingers wide and what about the Visibility and Accessibility to our operating field??
It’s weird!!! We work in a field in which people struggle to put a ‘burger and we are expected to do miracles…… and yes we are doing miracles.
Dentist has to perform detailed, meticulous procedures on a minute scale. Margin of error is in micro fractions, our instruments are sharp and invasive, and a blink of an eye or loss of concentration will result in damage of vital tissue which is unacceptable.
Hmmm… I think its enough of self praising!!
So what the hell is this so called “Good practical hand“???
It can be called as clinical dexterity in proper terms, I am going to use this term in whole article.
Let me define Dexterity- skill in performing task especially with hands.
The abilities which involve the use of hands develop over time, starting with primitive gestures such as grabbing at objects to more precise activities that involve precise eye–hand coordination. Fine motor skills are skills that involve a refined use of the small muscles controlling the hand, fingers, and thumb. The development of these skills allows one to be able to complete tasks such as writing, drawing, buttoning and finally doing dental procedures.
Motor skill is a learned sequence of movements that combine to produce a smooth, efficient action in order to master a particular task like doing dental procedures
- Gross motor skills include lifting one’s head,turning,moving head etc.Generally large muscles develop before smaller ones, thus, gross motor development is the foundation for developing skills.
- Fine motor skills include the ability to manipulate small objects,and various eye–hand coordination tasks. Some examples of fine motor skills are using the pincer grasp (thumb and forefinger) to pick up small objects,like holding endodontic files
- Ambidexterity is a specialized skill in which right and left both hands are equally dexterous and dentist can use any one of his hands as dominant one while working.
Positioning is very important for engagement in fine motor tasks. A Dentists seat should allow him to sit comfortably with his feet placed firmly on the floor. His hips, knees, and ankles should be at 90 degree angles, with his torso slightly forward. His operating field should be approximately at the level of his elbows when his arms are at rest at his side… Keep in mind that trunk stability is necessary for good mobility of the arms, hands, and fingers.
One more important factor for a dentist is good hand-eye coordination
hand–eye coordination is the coordinated control of eye movement with hand movement, and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes. its …
