Influence of lead apron shielding on absorbed doses from panoramic radiography

Abstract

In conclusion, the results of this study showed no statistically significant differences between a panoramic radiography with or without the use of lead apron shielding.

Radiation exposure to foetus and breasts from dental X-ray examinations: effect of lead shields

“…Recently, Rottke et al 20 found no statistically significant differences between absorbed organ doses in panoramic examinations with or without the use of lead apron shielding. The opposite was found by Buch et al, 19 who showed that the use of a lead apron in panoramic examinations significantly (72%) reduced the dose to the uterus.…”

Praktischer Strahlenschutz am Patienten in der radiologischen Diagnostik

“…Bei Untersuchungen von Panoramaaufnahmen und dentalen Cone-beam-CT-Bildern zeigten sich keine signifikanten Dosiseinsparungen durch das Tragen einer Patientenschürze [32][33][34].…”

Skin entrance dose with and without lead apron in digital panoramic radiography for selected sensitive body regions

“…A recent paper by Rottke and colleagues [10] found no significant differences in effective dose as assessed in an antropomorphometric phantom by means of thermoluminescence dosimeter (TDL). They concluded that the application of lead aprons Bhas only very little influence, if any, on the doses absorbed during a dental panoramic radiography^ [10]. While TLDs certainly are very useful for assessment of effective dose in such phantoms, their readout accuracy and reproducibility strongly depends on a variety of factors that have to be controlled [11].…”

“…For the thyroid, thyroid collars have been found effective for digital panoramic units yet interestingly not for storage phosphor-based systems [9]. A recent paper by Rottke and colleagues [10] found no significant differences in effective dose as assessed in an antropomorphometric phantom by means of thermoluminescence dosimeter (TDL). They concluded that the application of lead aprons Bhas only very little influence, if any, on the doses absorbed during a dental panoramic radiography^ [10].…”

“…Also, doses to be detected typically start in the low-μGy range [10,12], which is also in the order of magnitude of the lower detection limit [11] of the high-sensitivity lithiumfluorid TLDs that are commonly used today (e.g., in [10,13]). If the dose difference is very small as suggested, e. g., in [10], it thus appears useful to look into the actual difference using a direct measurement tool such as a highly sensitive solid-state-dosimeter. This would allow highly sensitive direct measurements for a few specific regions of interest.…”
