The effect of aging on the balance and quality of salivary ph in the oral cavity

Background and aim: The balance between salivary buffer capacity and salivary components plays a vital role in maintaining oral health. Aging, as a natural physiological process, affects various organs including the salivary glands, leading to changes in both the quantity and quality of saliva. These alterations influence salivary pH, which tends to decrease with age, potentially disrupting the oral ecosystem.

Purpose: This review is to evaluate the effect of aging on the balance and quality of salivary pH. 

Methods: This study employed a literature review approach, involving a comprehensive search of both international and national scientific articles through academic databases. The method enabled the synthesis of existing data and the detailed discussion of findings, providing a clear examination of the effects of aging on the balance and quality of salivary pH in the oral cavity. 

Result: Indicate that elderly individuals generally exhibit lower salivary pH and flow rates compared to younger adults. Reduced salivary secretion due to aging is often associated with complications such as xerostomia, plaque accumulation, dental caries, and periodontitis. Moreover, systemic factors like hypertension and medication use can further decrease salivary pH, worsening oral health conditions. In conclusion, aging significantly affects the balance and quality of salivary pH, which may lead to decreased salivary function and an increased risk of oral diseases.
