Question 307 · LDEK · Medically compromised patient

Select the correct statement describing tooth extraction management in patients with a history of radiation therapy involving the oral cavity, head and neck:

A. anaesthesia should involve agents with added vasoconstricting substances due to decreased drug diffusion in tissues that underwent radiation therapy.
B. before the procedure the oral cavity should be rinsed with a 2% chlorhexidine solution to reduce pathogens levels in the mouth.
C. it is not recommended to perform reconstructive operation of the alveolar process of the extracted tooth due to the risk of periosteal injury when the periosteum is raised away.
D. it is not recommended to place stitches over the wound due to the risk of additional mucosal injury during the stitching procedure and during stitches removal.
E. antibiotics should be started before the procedure and continued until the wound is healed.

Hint

Irradiated bone heals poorly and is prone to osteoradionecrosis — think about infection control around the whole healing period.
