Final answer:
True
Dental sealants are indeed used to protect the occlusal surfaces of teeth from decay, providing a barrier against cavities by covering places that are prone to bacterial accumulation. They complement other oral hygiene practices and are an effective preventative measure against tooth decay.
Step-by-step explanation:
The statement that dental sealants are used as a means of protecting the difficult-to-clean occlusal surfaces of the teeth from decay is true. These sealants are applied to the chewing surfaces of the back teeth where decay occurs most often. Dental sealants act as a barrier to prevent cavities by covering the surfaces that are susceptible to tooth decay, mainly due to the accumulation of food particles and bacteria.
Dental caries, or cavities, develop when bacterial colonies in the mouth metabolize sugary foods, resulting in acid production that damages the calcium crystals of the enamel. Regular dental cleanings, reduction in sugar consumption, using products with fluoride, and the application of dental sealants are all methods used to prevent tooth decay and maintain oral health.
Dental sealants, specifically, offer added protection by keeping those areas that are harder to clean shielded from the bacterial action that leads to decay. This is a preventative measure that complements daily brushing and flossing, as well as professional dental care.
