Pierre Fauchard (1678-1761): Pioneering Dental Surgeon of the Enlightenment Age.

Pierre Fauchard, widely referred to as the "Father of Modern Dentistry," fundamentally transformed the field with his seminal 1728 publication,  Born circa 1677 in Brittany, France, Fauchard's early exposure to severe dental conditions during his naval service catalyzed his pursuit of advancements in dental science. Upon transitioning from naval service to establish a practice in Angers, and subsequently gaining acclaim in Paris, Fauchard systematically documented and organized dental practices, encompassing oral surgery, orthodontics, periodontics, and prosthodontics, thereby laying the foundational framework for contemporary dental practices. Fauchard's innovations included the use of materials such as lead, tin, and gold for dental fillings and the introduction of early orthodontic techniques, notably the  His treatise also emphasized the importance of preventive care and oral hygiene, which provided a basis for modern dental hygiene protocols.

The Impact of Laser-Activated and Conventional Irrigation Techniques on Sealer Penetration into Dentinal Tubules.

The present study was aimed at comparing the efficacy of 1-hydroxyethylidene-1, 1-diphosphonic acid (HEDP) and ethylenediaminetetraacetic acid (EDTA) by using various final irrigation techniques on penetration of sealer. Traditional irrigation of root canals with a syringe limits the ability of sealer penetration. Various irrigants and activation techniques, including sonic and ultrasonic devices and various kinds of lasers, have been introduced to improve penetration of sealers into dentinal tubules.

Efficacy of Laser-Activated Irrigation and Conventional Techniques in Calcium Hydroxide Removal from Simulated Internal Resorption Cavities: Micro-CT Study.

This study aimed to evaluate the effectiveness of different irrigant-activation techniques for eliminating calcium hydroxide from an internal root canal resorption cavity by using microcomputed tomography (micro-CT). Several techniques and irrigants are inadequate for the complete removal of calcium hydroxide from an internal root resorption cavity. Recently, a few studies have investigated the effectiveness of various methods, but there has been no micro-CT study that compares the effectiveness of photon-induced photoacoustic streaming (PIPS) and shock wave enhanced emission photoacoustic streaming (SWEEPS) techniques.
