PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

Weanling female rats, Sprague-Dawley strain, separated into 3 groups, were fed on a caries test diet of MIT diet

number 200 and distilled water to determine the effect of contraceptive steroids on dental caries in young female

rats. At 50 days of age the first group received daily, 100 mcg norethynodrel plus 4 mcg mestranol in steroid diluent.

Group 2 received 4 times the above dose. Group 3 served as controls receiving only the steroid diluent. Rats were

sacrificed at 85 days and caries assessed by the method of Keyes. The molars were stained with Schiff's reagent.

Caries activity increased with an increase in dose. Mean buccolingual enamel lesions/rat increased with dose but

those with dentinal involvement and proximal lesions occurred only at the higher dose. Major and minor sulcal

lesions/rat in treated groups were significantly higher than controls, although all rats showed major sulcul lesions.

At high dose weight of submandibular glands increased. Absolute and relative parotid gland weight increased with

dose. Absolute adrenal gland weights remained the same. Absolute weight of thyroid glands and ovaries decreased

with dose. Several theories of action of steroids in increasing dental caries are suggested. (PubHealth.info
