Provision of complete dentures to a new denture wearer increases the salivary flow rate is well known. The new dentures act as an additional mechanical stimulus to the salivary reflexes, thus increasing the flow rate. The purpose of this study was to determine whether replacing complete dentures would elicit the same response. Unstimulated and stimulated whole and submandibular/sublingual (SM/SL) saliva were collected before inserting complete replacement dentures and again after 2 days and after 3 weeks of denture wearing. Unstimulated whole salivary flow rate increased significantly 2 days after inserting replacement dentures, decreasing at 3 weeks but remaining significantly above the baseline. Stimulated whole salivary flow rate increased significantly after 2 days but decreased to normal after 3 weeks. Stimulated and unstimulated SM/SL salivary flow rate increased significantly after 2 days, decreasing at 3 weeks while remaining significantly above the values found before denture insertion.
为新佩戴假牙者提供全口假牙会增加唾液流速，这是众所周知的。新假牙作为对唾液反射的额外机械刺激，从而增加流速。本研究的目的是确定更换全口假牙是否会引发相同的反应。在插入全口更换假牙之前、佩戴假牙2天后以及3周后，收集未刺激和刺激后的全唾液以及颌下/舌下（SM/SL）唾液。插入更换假牙2天后，未刺激的全唾液流速显著增加，3周时下降，但仍显著高于基线水平。刺激后的全唾液流速在2天后显著增加，但3周后降至正常水平。刺激和未刺激的SM/SL唾液流速在2天后显著增加，3周时下降，但仍显著高于假牙插入前的值。
