Abstract
Objectives: this study was aimed at comparing dental stress in children having their first dental visit to those returning for dental treatment using salivary biomarkers of stress including salivary cortisol (s-cortisol), Immunoglobulin-A (s-IgA) and alpha-amylase (s-alpha-amylase). Additionally, the study was aimed at monitoring the change in stress in new patients as they progressed from the waiting to the clinical areas. Study design: salivary samples were collected from 40 children who had not been to a dentist before and similar samples were collected from 40 children who were returning for completion of dental treatment. Salivary cortisol, s-IgA and s-alpha-amylase concentrations were obtained by Enzyme-linked Immunosorbent Assay (ELISA). Results: salivary cortisol levels were higher for new patients at the waiting area compared to that at the dental chair (p= 0.05). Salivary alpha-amylase significantly increased in new patients while being seated in the dental chair. Returning patients had higher s-a-amylase (p= 0.001) and s-IgA (p= 0.016) compared to new patients. Returning patients had the lowest level of s-cortisol when providers were faculty pediatric dentists than with students and interns (p= 0.035). Conclusions: children coming in for their first dental visit may experience dental stress at the waiting area before being seated for dental examination. Returning children may experience higher levels of stress compared to new child patients possibly due to previous dental exposure.
