The purpose of this review, therefore, is to examine (1) what is currently known regarding the physics of aerosol creation, (2) the types

The purpose of this study was to determine the frequency of bacterial colonization in these lesions and to characterize the bacterial community present in root ends and periradicular lesions. Thirty-four adult patients who presented for apicoectomy of persistent periradicular lesions after endodontic therapy were selected for the study and samples of periradicular tissue and resected root ends collected. Total bacterial levels were estimated for 34 paired periradicular lesions and root ends using real-time polymerase chain reaction with universal bacterial primers. Sixteen pairs of these samples were analyzed using ribosomal 16S cloning and sequencing for bacterial identification. Bacteria were detected more consistently and at higher levels in root ends. Periradicular lesions exhibited a diverse microbial profile with many uncultivated phylotypes. E...

Traumatic dental injuries are emergent situations that need a quick assessment and appropriate management. The proper diagnosis and treatment rendered determines the prognosis of the case. It is also important to have proper documentation, not only for medicolegal reasons but to have a baseline reference regarding the traumatic injury. Future treatment modalities and outcomes can be better managed with accurate documentation at the initial assessment. MEDICAL CONSIDERATIONS A comprehensive medical evaluation of the patient with traumatic dental injuries is required before any dental treatment is rendered. Patients with trauma may present with extensive injuries, some of which may be life-threatening, or they may have some preexisting medical condition that may affect the overall dental treatment. 1 A complete medical evaluation is usually performed by the physician. However, the treating dental clinician should be in a position to evaluate the general medical issues that may affect the emergency dental care to be provided. A detailed medical history should be taken as soon as possible. The clinician should review all systemic diseases, medications taken, allergies, hospitalizations, and other relevant points. Vital signs should be recorded. As the trauma is to the orofacial region, a quick evaluation of the respiratory and circulatory system should be done to confirm normal breathing and circulation.

This regenerative technique lies squarely in the endodontist's scope of practice, but children presenting with necrotic immature incisors may pose behavior management problems that endodontists are untrained and unwilling to handle. Treatment of these immature permanent teeth provides an excellent opportunity for collaboration and shared patient management between pediatric dentists and endodontists that can yield optimal clinical outcomes. The purpose of this paper was to report a series of 32 regenerative endodontic cases in 28 children treated at the Nationwide…
