Association between Chronological Age and IGF-1, IGFBP-3, and CTX Levels in Saliva of Children through Younger Adult Population with Varying Periodontal Status.

The quest for the most precise and non-invasive technology to monitor the pubertal growth spurt is driven by the role of growth determination in orthodontics. The objective of this study was to estimate the levels of salivary insulin-like growth factor-1 (IGF-1), IGF-binding protein-3 (IGFBP-3), and cross-linked C-terminal telopeptide of type I collagen (CTX1), and to analyze whether the levels of these biomarkers vary among different chronological age groups with and without periodontal disease. Eighty participants were divided into three groups based on their chronological age: group 1: 6−12 years; group 2: 13−19 years; and group 3: 20−30 years. The assessed clinical parameters included the simplified oral hygiene index (OHI-S), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment loss (CAL), and community periodontal index (CPI). Using ELISA kits, the IGF-1, IGFBP-3, and CTX1 levels in the saliva samples were estimated. The salivary concentration of IGFBP-3 was significantly associated with age and gender (p < 0.01). However, no significance was observed between subjects with and without periodontal disease. Significant associations existed between the values of IGF-1, IGFBP-3, and CTX1 in saliva among subjects from the various chronological age groups. Estimation of salivary IGF-1 and IGFBP-3 could serve as a useful tool in the assessment of growth maturity and bone remodeling patterns during orthodontic treatment planning.

Comparison of Salivary IGF-1, IGFBP-3, and CTX with Periodontal Status among Patients Belonging to Various Skeletal Maturity Groups.

PURPOSE: To compare the levels of salivary IGF-1, IGFBP-3, and CTX with periodontal status among patients belonging to various skeletal maturity groups. MATERIALS AND METHODS: This cross-sectional study was conducted on 80 participants 6 to 25 years of age. Based on skeletal maturity, the participants were categorised into 3 different stages: prepubertal, pubertal, and post-pubertal stages. The periodontal status of the participants was assessed using the simplified oral hygiene index (OHI-S), bleeding on probing (BOP), probing pocket depth (PPD), clinical attachment loss (CAL), and community periodontal index (CPI). The saliva samples were examined for IGF-1, IGFBP-3, and CTX using the respective ELISA kits. One-way ANOVA was used to determine statistically significant differences of means across the study groups for continuous variables. RESULTS: The study demonstrated statistically significant differences for the parameters OHI-S, bleeding on probing, PPD, CPI, and CAL (p < 0.05) depending on skeletal maturity stage. ANOVA test showed a statistically significant difference by stage in IGF-1, IGFPB3, and CTX (p < 0.01). CONCLUSION: An association exists between periodontal status and levels of salivary IGF-1, IGFBP-3, and CTX in patients belonging to various skeletal maturity groups.

Prevalence of tobacco usage and its effect on the periodontal health parameters in the mining employees and the general population - A comparative study

Objective: Comparison of the prevalence of usage of tobacco products and its effect on the periodontal health parameters of the mining laborers and the general population of Udaipur city, India. Materials and methods: the cross sectional study was performed on the sample of 980 adults including 500 mining employees and 480 subjects from the general population. The presence or absence of the tobacco products usage was noted. The ADA type III examination using the community periodontal probe was done. The data obtained was subjected to chi-square and Cramer' v statistical analysis. Results: 79.40% of the mining-employees and 61.67% of the general population used different tobacco products, the difference noted was statistically significant (p=0.000). The most common periodontal condition amongst the mining employees and the general population was the presence of calculus (39% and 35.63% respectively) followed by the 4-5mm periodontal probing depth (29.20% and 26.04% respectively). The difference spotted was significant (p=0.018). There was statistically significant difference between the tobacco users and non- users for the different periodontal conditions (p=0.000). Conclusion: the tobacco product usage was high in mining employees group. There was a positive correlation between the usage of tobacco products and the periodontal health parameters (AU)
