Abstract
BACKGROUND: The physical appearance of an individual plays a primary role as it influences the opinion of the viewer. For this reason, orthodontic therapy to improve perceived aesthetics is in high demand among patients. This factor, combined with the increase in the number of non-invasive facial aesthetic treatments, has led to the need to understand potential risk factors in the application of medical devices to the perioral skin in patients with fixed orthodontic appliances. The aim of this study was to evaluate in vitro heating of the orthodontic bracket following electromagnetic fields and negative pressure (V-EMF) used as an anti-aging treatment. METHODS: Two different types of titanium alloy wires, one made of "beta-Titanium" alloy and the other "Ni-Ti" (DW Lingual Systems GmbH-Bad Essen-Germany) were used. The orthodontic wires and brackets mounted on a resin mouth were covered with porcine muscle tissue, then subjected to anti-aging therapy with a Bi-one LifeTouchTherapy medical device (Expo Italia Srl-Florence-Italy) which generates a combination of vacuum and electromagnetic fields (V-EMF) already adopted for antiaging therapy. During administration of the therapy, the orthodontic brackets and porcine tissue were thermally monitored using a Wavetek Materman TMD90 thermal probe (Willtek Communications GmbH-Germany). In total 20 orthodontic mouths were used, 10 with Beta Titanium wires and 10 with Nickel Titanium wires. RESULTS: A temperature increase of about 1°C was recorded in each group. The outcome of the present research shows that the absolute temperatures measured on orthodontic appliances, which, despite having a slightly different curve, both show an increase in temperature of 1.1°C at the end of the session, thus falling well within the safety range of 2°C as specified by the standard CENELEC EN 45502-1. Therefore, V-EMF therapy can be considered safe for the entire dental system and for metal prostheses, which tend to heat up at most as much as biological tissue (+0.9°C/1.1°C vs. 1.1°C/1.1°C). CONCLUSION: In conclusion, anti-aging therapy with V-EMF causes a thermal increase on orthodontic brackets that is not harmful to pulp health.

Main findings
In an in vitro setup using porcine muscle tissue over orthodontic appliances, V-EMF anti-aging therapy produced an approximate 1°C temperature increase in both beta-titanium and nickel-titanium wire groups, with about a 1.1°C increase at the end of the session. Measured temperatures remained within the 2°C safety range specified by CENELEC EN 45502-1, and the authors conclude the thermal increase is not harmful to pulp health.
Outcomes measured
- Temperature change/heating of metallic orthodontic brackets and wires during V-EMF anti-aging therapy
- Thermal safety relative to CENELEC EN 45502-1 2°C limit
- Potential harm to pulp health (inferred via thermal increase)
Limitations
- In vitro model using porcine muscle tissue and a resin mouth rather than human subjects
- Exposure parameters (e.g., EMF frequency, intensity, session duration) not reported in the abstract
- Outcome limited to thermal monitoring; no direct biological/clinical endpoints measured
