Easing the Pain and Swelling After Wisdom Tooth Removal: The Promise of Photobiomodulation Therapy

by

Wisdom tooth extraction, while a common oral surgery, often comes with its share of discomfort. Post-operative pain, swelling (edema), and difficulty opening the mouth (trismus) are frequent challenges for patients. These complications can significantly impact a patient’s quality of life and recovery time. However, a growing body of evidence suggests that Photobiomodulation Therapy (PBM) may offer a significant advantage in easing the recovery process.   PBM, a non-invasive therapy, involves the application of low-level lasers or light-emitting diodes (LEDs) to specific areas. This therapeutic approach has gained traction in various medical fields due to its potential to:   In a recent double-blind clinical trial, in an article titled “PAIN, OEDEMA AND TRISMUS RESPONSES FOLLOWING PHOTOBIOMODULATION THERAPY IMMEDIATELY AFTER LOWER THIRD MOLAR EXTRACTION: RESULTS OF A RANDOMIZED, DOBLE-BLIND AND SPLIT MOUTH CLINICAL TRIAL,” written by GISELA CRISTINA VIANNA CAMOLESI and et. al. … Read more

Detecting Lou Gehrig’s Disease Markers in Teeth

by

An interesting article titled “Early life metal dysregulation in amyotrophic lateralsclerosis” appears in the Annals of Clinical and Translational Neurology written by Claudia Figueroa-Romero and et al. (pp. 872-882, 2020). The article seeks to explore if metal uptake is dysregulated during childhood in people later eventually diagnosed with amyotrophic lateral sclerosis (ALS) also known as Lou Gehrig’s disease. ALS is a disease that leads to paralysis and early death that is characterized by motor neuron degeneration and this causes the brain to lose its ability to initiate and control muscle movement. The majority of cases of ALS have no known cause but both genetic and environmental factors are suspected. In the article the researchers discuss how they collected permanent teeth from patients who had teeth extracted or who had died and were obtained at autopsy. The data included teeth from … Read more

Using Laser Therapy after Tooth Extraction to Improve Wound Healing

by

An interesting article titled “Does laser therapy improve the wound healing process after tooth extraction? A systematic review” written by Lemes et al., was published online on October 15, 2018 in Wound Repair and Regeneration. The authors sought out to review research on using laser therapy after tooth extraction to improve oral wound healing. It is believed that laser therapy could increase the oral wound healing process by stimulating cell regeneration, attenuating pain, and modulating the immune system. The researchers were motivated because using lasers to accelerate wound healing after tooth extraction has remained controversial.  The researchers performed a systematic review to assess the best evidence that could show whether laser therapy was beneficial for wound healing after tooth extraction or if it had no merits. The review was carried out by three researchers who used eight databases including: MedLine (PubMed), The … Read more

Lasers to Detect Tooth Enamel

by

A group of researchers in Australia and Taiwan led by Wang, Fleming, and their colleagues showed that they could analyze the health of  extracted human teeth using lasers. This is done by measuring how the surface of a tooth responds to laser-generated ultrasound. This allows them to then valuate the mineral content of tooth enamel. Enamel is the hardest and most mineralized substance of the human body which engulfs teeth in a protective layer. Enamel constantly undergoes a cycle of mineral loss and restoration, in which healthy teeth maintain a high mineral content. If the balance between mineral loss and gain is lost, teeth can develop areas of softened enamel which are precursors to cavities and damaged teeth. This research could lead to the ability to assess oral health and predict emerging dental problems, such as tooth decay and cavities … Read more
