Limited utility of salivary mineral content in prediction of fragility fractures among postmenopausal women.

Abstract

BACKGROUND:

Osteoporosis is a metabolic disease characterized by increased bone fragility. As it is characterized as a general skeletal disease, changes can also be seen in the stomatognathic system (edentulism, wrong fitting of dentures, etc.). The question is whether early changes in the salivary mineral content and acid-base balance may reflect skeletal status and risk of bone fracture.

OBJECTIVES:

The objective of the study was to evaluate whether minerals in the saliva were associated with skeletal fractures in a population of postmenopausal women.

MATERIAL AND METHODS:

In this observational study, dental examinations along with the collection of saliva were conducted in 117 randomly recruited women (mean age 64.6 ±5.9 years). The study group included 23 study participants with fractures, of which 10 had a history of osteoporotic fractures. Saliva samples for mineral content including copper (Cu), zinc (Zn), calcium (Ca), and phosphorus (P), as well as salivary pH were collected and analyzed to determine associations between salivary mineral content and fracture risk.

RESULTS:

As a result, the median pH value was 6.8, and the median levels for Cu (0.35 μmol/L), Zn (0.61 μmol/L), Ca (0.7 mmol/L), and P (6.64 mmol/L) were observed. No differences were noted in salivary mineral content and acid-basic balance between the fractured and non-fractured participants.

CONCLUSIONS:

The results of our study suggest that salivary mineral content has limited usability in predicting skeletal fragility in postmenopausal women when used alone.
