Conditions

Dental Caries, Female Infertility

Brief summary

Periodontal diseases and dental caries are initiated by a pathogenic biofilm, in a susceptible host, affecting the tooth periodontium and hard tissues. Its possible association with many biologic systems has been studied. In this study, researchers investigated association between oral health and female infertility, and what is the biological rationale for such relationship.

Detailed description

Power analysis was performed with the G-Power software package to determine sample size. To cover possible data loss, 10% of a group were added to each group. Medical and dental examination will be performed both of control and experimental groups. In dental examination decayed, missing, or filled teeth (DMFT) index will be used according to World Health Organization (WHO 1997) criteria. All teeth were visually using the International Caries Detection and Assessment System (ICDAS-II). To analyze the correlation between oral health status and female infertility linear regression test and for comparison of both the groups (case and control), two sample t test and chi square test were used.

Design outcomes

Primary

MeasureTime frameDescription
female infertility12 monthsWomen with normal hormone values and uterine cavity with at least one healthy fallopian tube. All male partners have a semen specimen with minimum 5 million motile sperm in the ejaculate.

Secondary

MeasureTime frameDescription
dental examination1 DayAll teeth were visually using the International Caries Detection and Assessment System (ICDAS-II). The chosen sites were recorded as: 0 = sound; 1. = first visible sign of noncavitated lesion seen only when the tooth is dried; 2. = visible noncavitated lesion seen when wet and dry; 3. = microcavitation in enamel; 4. = noncavitated lesion extending into dentine seen as an undermining shadow; 5. = small cavitated lesion with visible dentine: less than 50% of surface; 6. = large cavitated lesions with visible dentine in more than 50% of the surface. A single calibrated examiner measured probing depth-PD, clinical attachment level- CAL, plaque (Pl), and gingival indices (GI), bleeding on probing (BOP) at four sites per tooth using a manual periodontal probe (PCPUNC, Hu-Friedy, Chicago, IL, USA).
