今回も妊婦の患者に歯周治療を行うことで

早産抑制効果があるか調べた文献です。

アメリカの産婦人科クリニックでの調査です。

757名の歯周病に罹患している妊娠6~20週

の妊婦の内、378名に介入し

The purpose of this study was to test whether treating periodontal disease (PD) in pregnancy will reduce the incidence of spontaneous preterm delivery (SPTD) at < or = 35 weeks of gestation.

A multicenter, randomized clinical trial was performed. Subjects with PD were randomized to scaling and root planing (active) or tooth polishing (control). The primary outcome was the occurrence of SPTD at <35 weeks of gestation.

We screened 3563 subjects for PD; the prevalence of PD was 50%. Seven hundred fifty-seven subjects were assigned randomly; 378 subjects were assigned to the active group, and 379 subjects were assigned to the placebo group. Active treatment did not reduce the risk of SPTD at <35 weeks of gestation (relative risk, 1.19; 95% confidence interval [CI], 0.62-2.28) or composite neonatal morbidity (relative risk, 1.30; 95% CI, 0.83-2.04). There was a suggestion of an increase in the risk of indicated SPTD at <35 weeks of gestation in those subjects who received active treatment (relative risk, 3.01; 95% CI, 0.95-4.24).

Treating periodontal disease does not reduce the incidence of SPTD.

結果は積極的な歯周治療は

35週未満の早産または新生児の罹病率を

減少しなかった。

また、積極的な治療を受けた被験者は35週未満の

早産の発症率を増加する可能性が有る。

結論は歯周治療は早産のリスクを

減少しない、ということです。
