BACKGROUND/PURPOSE: Few studies have investigated the periodontal status of Taiwanese pregnant women. This study aimed to investigate the periodontal status of pregnant women and to examine its relation to oral hygiene.
This study randomly recruited 477 pregnant women. Among them, 203 women were in their first trimester. Forty-six women completed the study to the end of their third trimester. We also recruited 160 nonpregnant women as the control group. Clinical periodontal parameters were recorded and included probing pocket depth [PPD (mm)], clinical attachment level [CAL (mm)], gingival index simplified [GI-s (%)], and plaque index [PI (%)].
The GI-s of the pregnant group (PG) was higher than that of the control group [CG; (i.e., nonpregnant)], but only the third trimester was statistically significantly different (P < 0.001).The full mouth dental PI was higher in the PG than in the CG (P < 0.001), particularly in the interproximal areas. The mean PPD was greater in the PG than in the CG (P < 0.001) in all tooth areas. The mean CAL was higher in the PG than in the CG (P < 0.001), but no difference existed between the different trimesters. The CG had a higher percentage of sites with a shallow PPD, compared to the PG (P < 0.001); the PG had a higher percentage of sites with a PPD of 4-6 mm, compared to the CG (P < 0.001). Only the PI of the full mouth and lingual tooth surfaces in the third trimester were better than in the first trimester throughout the pregnancy.
Gingival inflammation in pregnant women is positively correlated with the increased deposition of a dental plaque biofilm.
背景/目的：很少有研究调查台湾孕妇的牙周状况。本研究旨在调查孕妇的牙周状况，并探讨其与口腔卫生的关系。
本研究随机招募了477名孕妇。其中，203名女性处于孕早期。46名女性完成了整个孕晚期的研究。我们还招募了160名非孕妇作为对照组。记录临床牙周参数，包括探诊深度[PPD（mm）]、临床附着水平[CAL（mm）]、简化牙龈指数[GI-s（%）]和菌斑指数[PI（%）]。
孕妇组（PG）的GI-s高于对照组[CG；（即非孕妇）]，但只有孕晚期在统计学上有显著差异（P < 0.001）。PG组的全口牙菌斑指数高于CG组（P < 0.001），尤其是邻面区域。PG组所有牙位的平均PPD均大于CG组（P < 0.001）。PG组的平均CAL高于CG组（P < 0.001），但不同孕期之间无差异。与PG组相比，CG组PPD较浅的部位百分比更高（P < 0.001）；与CG组相比，PG组PPD为4 - 6mm的部位百分比更高（P < 0.001）。整个孕期中，仅孕晚期全口和舌面的菌斑指数比孕早期有所改善。
孕妇牙龈炎症与牙菌斑生物膜沉积增加呈正相关。
