The Role of Parathyroid Hormone in Alveolar Bone Resorption on Postmenopausal Women

Abstract

Background: Postmenopausal women exhibit reduced bone mineralization, which causes bone resorption, including that of alveolar bone. Parathyroid hormone has been shown to play a role in alveolar bone resorption. Objective: This study aims to analyze relationships between parathyroid hormone and other factors that may contribute to alveolar bone resorption in postmenopausal women. Methods: This cross-sectional study included 82 postmenopausal women aged 50–74 years, who resided in Central and East Jakarta, Indonesia. Subjects' data were obtained through questionnaires, dental examinations, and blood collection for the examination of parathyroid hormone levels by enzyme-linked immunosorbent assay and using panoramic radiography to measure bone resorption. Results: Spearman correlation analysis showed a significant correlation between parathyroid hormone level (p = 0.005) and extent of alveolar bone resorption, but age (p = 0.292), menopausal duration (p = 0.244), and number of missing teeth (p = 0.517) were not significantly correlated with the extent of alveolar bone resorption. Conclusion: Various factors play a role in the mechanism of bone resorption, so knowing the role of each factor is expected to reduce the effects of alveolar bone resorption that occurs in postmenopause. Among the factors investigated in this study, the parathyroid hormone was the sole factor correlated with postmenopausal alveolar bone resorption.

A comprehensive review of the bioactive components of sesame seeds and their impact on bone health issues in postmenopausal women

“…31 As a result of the calcium inadequacy and impaired absorption caused by estrogen deficiency, the prevalence of osteoporosis and other bone issues increases in the postmenopausal period, which causes bone abnormalities such as osteopenia and osteoporosis. 32…”

Effect of Hypoestrogenism on Oral Cavity

“…Periodontal bacteria are the main cause of periodontitis which initiates periodontitis; the host response also determines the progression and severity of the disease. Alteration of the immune response of the host and surrounding cells by periodontal pathogens and their virulence factors results in a complex network of pro-and anti-inflammatory cytokines that play a role in periodontal disease [54,55].…”

The aging process and its relation to periodontal conditions

“…Along with the aging process, there is a decrease in fibroblasts and a more organized structure in the periodontal ligament, concomitant with changes in the gingival connective tissue. In addition, there is an increase in the width of the cementum, which is more significant in the apical and lingual areas [62,63].…”
