6.5.3 Recommended angle and default exposure time for each tooth
type
The parameters built into the tooth position are set for people of average
size. Individual results may vary based on a number of factors, including
image density preferences, different imaging sensors or film speeds and
brands available, patient size, and physician techniques and preferences.
The use of devices designed for medium sized adults and exposure
Settings can lead to excessive radiation exposure in small patients,
especially children. Pediatric patients may be more sensitive to radiation than
adults (i.e., higher cancer risk per unit dose of ionizing radiation), so
unnecessary radiation exposure is particularly important for pediatric patients.
When using HyperLight-G, consider the patient's age, body size, physical
habits, and clinical indications when validating the exposure time Settings.
