Traumatic dental injuries constitute a significant public health problem, particularly among children and adolescents, with approximately one-third of individuals experiencing a dental trauma before adulthood. The International Association of Dental Traumatology periodically updates evidence-based guidelines for the management of these injuries. This article synthesizes the current IADT recommendations, covering crown fractures, luxation injuries, root fractures, and avulsion, and discusses emergency management protocols, splinting techniques, follow-up regimens, and factors influencing long-term prognosis.

Chemomechanical debridement through irrigation is fundamental to endodontic success, eliminating microorganisms, dissolving organic tissue, and removing the smear layer from the complex root canal system. This article reviews contemporary irrigation protocols, compares the properties and efficacy of sodium hypochlorite, EDTA, chlorhexidine, and newer irrigants, and evaluates activation techniques including passive ultrasonic irrigation, sonic activation, laser-activated irrigation, and negative pressure systems.

Conventional oral examination remains the cornerstone of oral cancer screening, but adjunctive diagnostic tools have been developed to improve the detection of potentially malignant disorders and early malignancy. This article evaluates the evidence supporting toluidine blue staining, autofluorescence devices, chemiluminescence, brush biopsy, and salivary biomarkers as adjuncts to visual and tactile examination, discusses their sensitivity and specificity, and provides a practical framework for incorporating these tools into clinical practice while avoiding over-referral and unnecessary patient anxiety.
