Relationship Between Oral Health Status and Unexplained Female Infertility in Turkish Population

Overview

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.

Full Title of Study: “Oral Health Status and Unexplained Female Infertility”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Cross-Sectional
  • Study Primary Completion Date: April 15, 2019

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.

Interventions

  • Other: Intraoral and Radiographic Dental Examination
    • (ORTHOPANTOMOGRAPH® OP300 PANORAMIC, Instrumentarium Dental, Tuusula, Finland,63 kVp, 0.8 mA, 0.5 s).

Arms, Groups and Cohorts

  • female infertility
    • Women who had regular menses and can’t conceive despite a long-term regular sexual intercourse for more than 12 months
  • healthy
    • healthy patients who had minimum two normal pregnancies

Clinical Trial Outcome Measures

Primary Measures

  • female infertility
    • Time Frame: 12 months
    • Women 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 Measures

  • dental examination
    • Time Frame: 1 Day
    • All teeth were visually using the International Caries Detection and Assessment System (ICDAS-II). The chosen sites were recorded as: 0 = sound; = first visible sign of noncavitated lesion seen only when the tooth is dried; = visible noncavitated lesion seen when wet and dry; = microcavitation in enamel; = noncavitated lesion extending into dentine seen as an undermining shadow; = small cavitated lesion with visible dentine: less than 50% of surface; = 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).
