Lecture: Hemolasertherapy : A pioneering technique that use  a patient with own stem cells “in loco” to regrow gingiva and bone: translational in vitro and in vivo study

Introduction and objective:

The purpose of this presentation was to explore the possibilities for the translational application of Photobiomodulation (PBMT) to regenerate gingival tissues and grow interdental papilla using the Hemolasertherapy (HLT) technique. This presentation will explore all potential mechanisms and the role of laser light, both low-level laser and Er: YAG laser, to achieve complete regeneration of the papilla and bone in some clinical situations.

Methods: (PBMT) used a 660nm diode laser (Laser Duo, MMO-Sao Carlos, SP, Brazil), punctual, contact mode in two steps: before the bleeding (first PBMT) and immediately after bleeding (second PBMT). Parameters used were:  power output: 100mW, CW; diameter tip: 5mm; spot area: 0.19cm2; irradiation exposure time per point: 20 secs; 14 points per session; total of 2 sessions, with a 1-week interval; E: 2J per point; E: per session, 28J; irradiance per point: 0.52W/cm2 ; fluence per point: 10.4 J/cm2 . Total in two sessions: total energy: 56J; total fluence: 294.75J/cm, total time: 560 secs. Simultaneously, an in vitro preliminary study was carried out to demonstrate what could happen at cellular level in clinical cases where hemotherapy was associated with PBMT laser application. In a recent publication the authors introduced the Lite Touch (Israel) Er:YAG laser, which achieved excellent clinical results in bone defects using energy in a gentle mode (≤ 0.8Watts). This presentation will show the results of 3 papers published by the authors about Hemolasertherapy.

Results: These studies demonstrated that the blood clot originated from the bleeding provoked in the gingival area is rich in mesenchymal stem cells. PBMT enables their preservation, viability, and further differentiation, stimulating the return of gingival stem cells, which would support their survival and differentiation in the blood clot, thus favoring interdental papilla regeneration. The association with Er YAG is a promising use for decontamination of bone and in cases of peri-implantitis.

 Conclusions:

Hemolasertherapy is a new and revolutionary step/tool in tissue regeneration based on PBMT of MSCs of the blood itself (autologous).

In addition, the use of Er:YAG laser showed excellent clinical results in cases of bone defects.

Background and Objectives: The objective of this presentation is to demonstrate innovative uses of lasers in aesthetic dentistry. The authors will present a new Er:YAG laser (LiteTouch, Israel) with potential to remove caries , dentin , enamel , cemented ceramic laminates and soft plastic surgery, and also peri-implantitis treatment. According to Shibli 2018, cleaning/decontamination of dental implant surfaces by means of high and low-intensity laser therapy using Er:YAG has also been employed. The Laser irradiation removes not only the inflammatory soft tissue around the peri-implant pocket but also detoxifies the implant surface without damaging or altering the titanium surface or dental implant morphology, allowing a better stabilization of the blood clot with or without the addition of bone graft materials during the guided bone regeneration. Additionally, authors have been publishing in the last 20 years several scientific papers showing that the wavelengths of Erbium lasers coincide with the absorption peak of water and hydroxyapatite, resulting in microexplosions which can remove hard dental tissues. The carious tissues contain a higher amount of water compared to healthy tissues, making a greater interaction between the Er:YAG laser and the organic substrate. This high selective absorption indicates zones of high absorption, thus obtaining selective caries removal. The equipment can irradiate with several different levels of energy (mJ) and frequency (Hz) which are selected by the operator on each clinical indication. In the soft tissues, fast and efficient cutting was observed, such as removal of gingival hyperplasia and gingival contour and tissue decontamination. Another clinical use of Er:YAG laser is for removal of ceramic restorations, offering an alternative to high-speed burs, promoting a less invasive procedure to the underlying tooth structure. It can be used to efficiently, safely and predictably remove all porcelain laminates and veneers. Currently, with the development of more adequate parameters, the removal of these veneers can be done in 30 to 60 seconds each, depend ending on the thickness and type of ceramic. Also, normally it can be performed without the use of anesthesia. In conclusion, the Er:YAG laser is a modern method to improve the quality of dental functional and aesthetic procedures.
