Objective:
To assess inequalities in the availability of NHS dental services between Health Boards in Scotland.
Study Design:
Postal questionnaire survey of all dentists (n = 2,852) registered with the General Dental Council at an address in Scotland.
Methods:
Data obtained on NHS working hours were used to model dentist to population (D/P) ratios and primary care D/P ratios corrected for part time working, variation in service productivity and the provision of private services.
Results:
A total of 2,134 completed questionnaires (74.8%) were received. There was a wide variation in D/P ratios between Health Boards. Dumfries & Galloway and Grampian had the lowest, and Tayside and Greater Glasgow the highest D/P ratios, irrespective of method of calculation. The corrected D/P ratios for the other Health Boards were more similar than was suggested by the simple ratios of registered dentists to population size.
Conclusions:
There was considerable variation in the availability of NHS dental practitioners between Health Boards. Simple ratios of registered dentists to population size can mask the true availability of specific dental services such as NHS dental care.

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.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
