Radiology is an essential component of dental diagnosis. Available
data clearly show that ionizing radiation, if delivered in sufficient
doses, may produce biological damage. However, it is not clear
that radiation in doses required for dental radiography presents
any risk. Neither is it clear that these small doses are free of risk.
Operative dentistry is a significant part of clinical dentistry, with
practitioners in the UK spending more than 60% of their time placing
and replacing direct restorations. In tandem with this many root canal
treatments are carried out and increasingly more indirect restorations
are placed. All practitioners whatever their discipline will remember
developing their manual skills while engaged in these procedures
during their student days.
This study characterized maxillary sinus mucositis (SIMS) adjacent to teeth with apical periodontitis
(AP), and assessed its resolution three months after endodontic treatment. 29 subjects who maxillary
posterior teeth with AP were imaged with cone-beam computed tomography (CBCT). Resolution of
SIMS was assessed with CBCT three months after treatment, and periapical healing was assessed
using the PAI after six months. Four non-compliant subjects were discontinued and SIMS was
identified in 14/25 subjects (56%).
