Abstract - A pilot study to determine whether 452 regular oral contraceptive users had a higher earies prevalence than 114 women not using those preparations found no significant variation between groups. Thus assumptions drawn from previous rodent studies do not justify the initiation of more complex laboratory-based human investigations. Key words: contraceptives, oral; dental earies. K.. W. Stephen, Department of Oral Medicine, University of Glasgow Dental School, 378 Sauchiehall Street, Glasgow G2 3 JZ, Scotland. Accepted for publicalion 25 December 1978.
It has been suggested that oral contraceptives can increase the caries rate in rats (3), thus a pilot study was conducted to investigate the relationship betweeti human caries prevaletice and usage of different oral contraceptive formulations.
METHODS, RESULTS AND DISCUSSION I Subjects comprised two groups of women, one atI tending an outpatietit Obstetric Clinic and the I other, a Family Planning Centre. All except controls I were taking, or had used, oral cotitraceptives for at I least 6 months and the same questionnaires were I completed at each location to collect caries and oral I hygiene data. Results relating to the study population, 452 of whom used, or had used, an oral cotitraceptive with one of three basic formulatiotis and 114 woiiieti using other methods, are shown in Table 1 A-B. I Of the dentally related data in Table 1 A only the | m e a n ages (P < 0.01) and DMFS values {P I < 0.001) of those in the control and the high I oestrogen group (Group "C") were significantly (different. As Group "C" participants were older, I separate analyses were instituted here (using Stu|O3Ol-5661/79/030183-02$ 02.50/0
