Key result
Dental variables, including malocclusion, temporomandibular disorder, and dental surgery, are strongly associated with reduced heart rate variability, indicating altered cardiac autonomic modulation.
Why the study?
Is there an association between dental variables (malocclusion, TMD, dental surgery) and heart rate variability?
Is there an association between dental variables (malocclusion, TMD, dental surgery) and heart rate variability?
Dental conditions and procedures, such as malocclusion, TMD, and dental surgery, are associated with reduced heart rate variability, indicating altered cardiac autonomic modulation.
Supports dental screening in low-HRV patients; hypothesis-generating for causality, needing RCTs before practice change.
The heart rate variability is a useful method to assess cardiac autonomic modulation in patients undergoing dental procedures, because knowledge of physiological conditions provides greater security to the professional as well as the possibility of a better plan treatment to patient benefit. The aim of our study was to describe the association between cardiac autonomic control and dental variables. We consulted the databases Medline, SciELO, Lilacs and Cochrane, using the terms "autonomic", "dentistry", "heart rate variability", "cardiovascular physiology." The selected studies indicated a strong relationship between dental variables and HRV. There was an association between malocclusion, TMD, dental procedures cirugia and low HRV. Thus, they become more studies that relate to HRV in dental science, especially in clinical practice.

Santana et al. (2013) conducted a review in Dental procedures and oral conditions (n=4). Dental variables (malocclusion, TMD, dental surgery) vs. Healthy controls or baseline states was evaluated on Heart rate variability (HRV). Dental variables, including malocclusion, temporomandibular disorder, and dental surgery, are strongly associated with reduced heart rate variability, indicating altered cardiac autonomic modulation.
