While there are numerous choices for provisionalization, this technique is advantageous when a patient presents with an immediate need for temporization and there is limited time in the schedule for both the patient and provider. Providing an efficient solution using readily available materials that address the esthetics, function and reduction of sensitivity until the patient can be appointed for definitive treatment is illustrated.

Zeitlin’S Top 200 Dental Deckades (January 2024), Benjamin D. Zeitlin

Pacific Open Texts

Pharmacology courses in any institution are information intensive with a constant, high volume of new material. With that in mind, the standards that the American Dental Education Association set for Pharmacology include that: “the student must identify the influences drugs taken for non-dental purposes may have on a proposed treatment (…) and the student must recognize therapeutic agents used in the routine practice of clinical dentistry.” This requires that students at a minimum, recognize common drugs and know their major implications for dental therapy.

This learning tool has been created to address the drug recognition aspect of that standard.

Gingival Crevicular Flow (Volume) As A Biomarker Of Orthodontic Tooth Movement, Harrison Truman, Nina Stevens, Tyler Starley

Excellence Day

Tooth movement is caused by the application of force. In short, applied force strains structures present in the PDL space – cells, ligaments, blood vessels. Cells in the PDL are damaged by extension and by diminished oxygen supply due to compression of blood vessels. Compounds released from damaged or dead cells trigger an innate inflammatory response. One of the biomarkers of that response is increased formation of extracellular fluid (edema), specifically gingival crevicular fluid (GCF). Our goal is to monitor changes of GCF flow during the orthodontic treatment with Invisalign.

Adhesion And Minimally Invasive Dentistry, Sana Mohd, Javid Shaikh, Vidhi Bhuva, Vishwash Patel

Excellence Day

G. V. Black, the father of modern dentistry believed in extension for prevention. Today we have come a long way. We practice minimally invasive dentistry which is possible because of adhesion. We have eight generations of bonding systems. 4th generation is the gold standard, while 6th ,7th and 8th are used extensively. Direct restorations which involve minimally invasive procedure alternatives for carious lesion management, include the use of sealants, infiltration, atraumatic restorative treatment (ART), and selective carious tissue removal (e.g., indirect pulp capping, stepwise removal, or selective removal to soft dentine). Due to adhesion and the invention of higher quality …

A Review Of External Cervical Resorption, Sarah Makkiyah, Max Kazantcev

Excellence Day

Invasive cervical resorption (ECR) is a complex form of external resorption. It is distinguished by its localization, its invasive nature, and the formation of a mineralized replacement tissue resembling cellular cementum. During initiation of ECR, the portal of entry is the cementum below the gingival epithelium, and resorption starts with localized destruction and removal of PDL. Response to PDL injury includes formation of a blood clot and inflammation, followed by granulation tissue, recruitment of macrophages, and multinucleated-cell differentiation.
