The impact of dental operating microscopes on the success rates of endodontic treatments

Recent advancements in dental technology, such as magnification devices like loupes and surgical microscopes, have greatly improved the accuracy and quality of root canal treatments. Dental operating microscopes (DOMs) have become widely accepted in endodontics, providing enhanced visualization and facilitating precise identification of anatomical landmarks, root canal orifices, and pulp remnants. The increased magnification and illumination offered by DOMs have improved treatment outcomes by enabling more efficient removal of bacteria, debris, and obturation materials from the root canal system. Studies have shown that the use of DOMs can significantly increase the success rates of endodontic treatments, allowing for the identification and treatment of even the smallest canals and anatomical variations. Additionally, DOMs enhance ergonomics, patient communication, and documentation in dental practice. However, challenges such as cost and limited office space hinder their widespread use. Increased education and awareness of the benefits of operating microscope utilization are essential for its broader adoption in endodontic procedures.

Photodynamic therapy and periodontal disease

Periodontal diseases are global health concern since they affect almost 20-50% of global population and are widespread in both developed and developing countries. Periodontal disease develops as result of persistent infection caused by different periodontopathic bacteria and inflammation of tooth's supporting tissue. Traditional methods of periodontal care involve mechanical removal of biofilm and using antibiotics and antibacterial disinfectants as supplemental measure. However, in locations with restricted access, removal of plaque and decrease in quantity of pathogenic organisms may suffer. Furthermore, increased antibiotic resistance has led to development of newer therapeutic modalities, including photodynamic therapy (PDT). Application of PDT in periodontics, such as pocket debridement, gingivitis, and aggressive periodontitis, continues to develop into fully developed clinical therapeutic modality and is regarded as potential new strategy for eliminating pathogenic bacteria in periodontitis. Photosensitizer activated by light of certain wavelength in presence of O2 is used in PDT, potent laser-initiated photochemical reaction. Because traditional therapy, such as scaling and root planing, is ineffective at entirely eliminating periodontal infections, especially in deep periodontal pockets, antimicrobial PDT may be viewed as alternate therapeutic approach. Additionally, dual selectivity of PDT, which restricts damage to healthy tissues, gives it competitive advantage over alternative therapies. Purpose of this research is to review the available information about PDT and periodontal disease.
