Table 4. Odds ratios for benign paroxysmal positional vertigo associated with different kinds of dental procedures.
| Variable | 1-month risk of BPPV | |
|---|---|---|
| Crude OR(95% CI) | Adjusted OR*(95% CI) | |
| Without dental procedures | 1 | 1 |
| Dental scaling | 1.43(0.93–2.21) | 1.42(0.91–2.21) |
| Prosthodontics | 1.61(1.01–2.56) | 1.61(1.01–2.59) |
| Endodontics | 1.35(0.63–2.88) | 1.36(0.63–2.93) |
| Oral surgery | 2.15(1.36–3.40) | 2.24(1.41–3.56) |
| Periodontics | 3.36(2.01–5.61) | 3.35(1.99–5.63) |
BPPV = benign paroxysmal positional vertigo; OR = odds ratio; CI = confidence interval
