[Tooth Mobility Evaluation -A Comparison with Dental Assessment-]
Background:
Patients with mobile teeth are at an increased risk of tooth injury related to tracheal intu- bation. Although the presence/absence of mobile teeth is confirmed through interviews during preoperative visits, patients are frequently unaware of the presence of such teeth. In our facility, dental consultation is pro- vided for all patients undergoing thoracoscopically- assisted surgery as part of the management of oral hygiene. This study examined the presence/absence of mobile teeth reported by patients during preoperative visits and those identified on dental consultation, focus- ing on the inconsistency between them.
Methods:
Patients who had undergone thoraco- scopically-assisted surgery in our facility between Janu- ary and October 2014 were retrospectively studied. Tooth mobility was evaluated using the Miller index.
Results:
Among the 76 (46 males and 30 females) patients aged 36 to 88 (mean: 67.8), mobile teeth were identified on dental consultation in 13 and reported during preoperative visits by 8.
Conclusions:
Based on this findings, it may be nec- essary to pay sufficient attention when inserting tubes even when mobile teeth have not been reported by patients during preoperative visits.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
