Kissing is a common social behavior that may influence physiological responses and impact oral health. Prior research has shown that affectionate behaviors like kissing can reduce stress and improve relationship satisfaction. However, the effects of kissing on salivary pH, particularly after consuming sugary or fermented beverages, have not been thoroughly investigated.
This study aims to determine whether kissing accelerates salivary pH recovery following the consumption of sugary or fermented beverages.
A randomized controlled trial will be conducted with 60 couples aged 18-30 years. Participants will be divided into 3 groups: a control group (no kissing), an experimental group where one partner consumes a beverage, and another experimental group where both partners consume a beverage. The study will measure salivary pH at baseline, after beverage consumption, and following a 40-second kiss or control period, with measurements taken every 5 minutes until the pH returns to neutral levels. The data will be analyzed using SPSS software (IBM Corporation). ANOVA will be used to compare salivary pH recovery between groups, and if assumptions of normality or sphericity are not met, alternative models such as generalized linear models or nonparametric tests will be considered.
The study is ongoing, with participant recruitment already initiated and preliminary data collection in progress. The study was funded by the Catholic University of Santiago de Guayaquil from June 2024 to June 2025. Ethics approval was obtained in June 2023. The results are expected to be published in the last quarter of 2025.
This study will provide insights into the relationship between kissing, salivary pH, and oral health, potentially offering new strategies for the prevention of dental caries. The results may challenge existing assumptions about the role of kissing in oral health.

亲吻是一种常见的社交行为，可能会影响生理反应并对口腔健康产生影响。先前的研究表明，像亲吻这样的亲昵行为可以减轻压力并提高关系满意度。然而，亲吻对唾液pH值的影响，尤其是在饮用含糖或发酵饮料后，尚未得到充分研究。
本研究旨在确定亲吻是否能加速饮用含糖或发酵饮料后唾液pH值的恢复。
将对60对年龄在18至30岁之间的夫妇进行一项随机对照试验。参与者将被分为3组：对照组（不亲吻）、一个伴侣饮用饮料的实验组和两个伴侣都饮用饮料的另一个实验组。该研究将在基线、饮用饮料后以及40秒亲吻或对照期后测量唾液pH值，每5分钟测量一次，直到pH值恢复到中性水平。数据将使用SPSS软件（IBM公司）进行分析。方差分析将用于比较各组之间唾液pH值的恢复情况，如果不满足正态性或球形性假设，将考虑替代模型，如广义线性模型或非参数检验。
该研究正在进行中，已经开始招募参与者并正在进行初步数据收集。该研究由瓜亚基尔天主教大学于2024年6月至2025年6月资助。2023年6月获得伦理批准。预计结果将于2025年最后一个季度发表。
本研究将深入了解亲吻、唾液pH值和口腔健康之间的关系，可能为预防龋齿提供新策略。研究结果可能会挑战关于亲吻在口腔健康中作用的现有假设。
