To assess the relationships among alkali production, diet, oral health behaviors, and oral hygiene.
Data from 52 subjects including demographics, diet, and oral hygiene scores were analyzed against the level of arginine and urea enzymes in plaque and saliva samples. An oral habit survey was completed that included: use of tobacco (TB), alcohol (AH), sugary drinks (SD), and diet. Alkali production through arginine deiminase (ADS) and urease activities were measured in smooth-surface supragingival dental plaque and un stimulated saliva samples from all subjects. ADS and urease activities were measured by quantification of the ammonia generated from the incubation of plaque or saliva samples. Spearman correlations were used to compute all associations.
Participants in the lowest SES (Socio-economic status) group had the habit of consuming sugary drinks the most and had the highest rate of tobacco use. Males consumed significantly more alcohol than females. No significant relationship was found between age or gender and alkali production. Higher rates of sugary drink consumption and tobacco use were significantly related to lower alkali production.
The study showed a relationship between alkali production and oral hygiene, diet, and certain oral health behaviors. Poor oral hygiene was significantly associated with age, lower SES, tobacco use, and alcohol, and sugary drinks consumption. Clinical relevance Certain oral health behaviors have an impact on oral hygiene and on alkali production; it is important to address these factors with patients as a strategy for caries control.
评估碱生成、饮食、口腔健康行为和口腔卫生之间的关系。
分析了52名受试者的数据，包括人口统计学、饮食和口腔卫生评分，并与菌斑和唾液样本中的精氨酸和尿素酶水平进行对比。完成了一项口腔习惯调查，内容包括：烟草使用（TB）、酒精摄入（AH）、含糖饮料（SD）和饮食情况。测量了所有受试者平滑面龈上牙菌斑和未刺激唾液样本中通过精氨酸脱亚氨酶（ADS）和脲酶活性产生的碱。通过对菌斑或唾液样本孵育产生的氨进行定量来测量ADS和脲酶活性。采用Spearman相关性分析计算所有关联。
社会经济地位（SES）最低组的参与者饮用含糖饮料的习惯最普遍，且烟草使用率最高。男性饮酒量显著高于女性。未发现年龄或性别与碱生成之间存在显著关系。较高的含糖饮料消费率和烟草使用率与较低的碱生成显著相关。
该研究表明碱生成与口腔卫生、饮食和某些口腔健康行为之间存在关联。口腔卫生差与年龄、较低的社会经济地位、烟草使用、酒精摄入以及含糖饮料消费显著相关。临床意义某些口腔健康行为会影响口腔卫生和碱生成；作为龋齿控制策略，向患者强调这些因素很重要。
