Multi-Scale Characterization of Conventional and Immediate Dental Implant Systems.

We hypothesized that the different post-implantation healing stages between the conventional and immediate implantations produce different amounts and tissue composition of the peri-implant bone. Thus, the objective of the current study was to examine whether the stability of dental implant systems is associated with characteristics of the interfacial bone area at different post-implanation healing periods. Mandibular molars were extracted from each beagle dog.

Stability of Epinephrine in a Normal Saline Solution.

Objective: Dilution of concentrated epinephrine prior to intravenous use during clinical emergencies can delay urgent interventions. The objective of this study was to determine whether diluted epinephrine remains stable and sterile over time in common hospital settings.

Methods: Epinephrine samples were prepared by clinically relevant double dilution techniques.

Regulatory barriers to dental anesthesia services for special populations.

Aims: Sedation and general anesthesia are necessities for the treatment of many individuals within special populations such as those with physical and intellectual disabilities, fear/anxiety, or individuals requiring extensive procedures. This study aims to discover regulatory factors that may be contributing to the limited access to anesthesia services provided by dentist anesthesiologists.

Methods And Results: The study included an online survey completed by self-reported dentist anesthesiologists with 2 or more years of formal anesthesia training.

The Effect of Parathyroid Hormone Analogues When Added to Mineralized Bone Xenografts.

Implants can be a treatment option when there is sufficient quantity and quality of bone to provide support for long-term success. In the reconstruction of defects, autogenous bone remains the gold standard for its osteogenic and compatibility properties. However, the disadvantage of secondary surgery and the associated donor site morbidity prompts researchers to develop the ideal bone substitute for optimum bone reconstruction.

Malignant Hyperthermia: A Case Study in the Dental Ambulatory Surgery Setting.

Historically, patients who developed malignant hyperthermia had an extremely high rate of mortality. Today, if treated appropriately, patients who experience an episode of malignant hyperthermia will most likely survive. This dramatic decrease in mortality associated with malignant hyperthermia is due to several factors, including an increased understanding of the disease, improved diagnostic and monitoring equipment, and the development of lifesaving pharmacologic agents.

What Is the Outcome of an Incision and Drainage Procedure in Endodontic Patients? A Prospective, Randomized, Single-blind Study.

Introduction: There are no prospective endodontic studies to determine the outcome of an incision and drainage (I&D) procedure for swelling in healthy, endodontic patients. The purpose of this prospective, randomized, single-blind study was to compare the postoperative course of I&D with drain placement versus a mock I&D procedure with mock drain placement after endodontic debridement in swollen emergency patients with symptomatic teeth and a pulpal diagnosis of necrosis.

Methods: Eighty-one adult emergency patients presenting with clinical swelling received either penicillin or, if allergic, clindamycin and complete endodontic debridement, and then were randomly divided into 2 treatment groups: I&D with drain placement or a mock I&D procedure with mock drain placement.

Tube Decompression for Staged Treatment of a Calcifying Odontogenic Cyst-A Case Report.

The calcifying odontogenic cyst is a rare developmental odontogenic lesion with a distinguishing cystic lining containing "ghost" epithelial cells. The variation in clinical, radiographic, and histologic findings makes the treatment decision difficult for these lesions. There are very few reports on treatment, with enucleation and curettage being the standard surgical method of choice for the cystic type and excision of the tumor for the solid type.

Lateral tarsotomy: a practical alternative to lateral canthotomy to increase orbital access.

Objective: Transconjunctival approach to the lower one-third of the orbit is commonly used to avoid transcutaneous incisions when surgical access is needed. A lateral canthotomy is used in conjunction with this approach if increased lateral exposure is required. A major disadvantage to lateral canthotomy is difficulty in resuspension of the lateral canthal tendon, which can lead to unaesthetic outcomes.

Significance of circulating tumor cells in patients with squamous cell carcinoma of the head and neck: initial results.

Objectives: to present and discuss a high-performance negative depletion method for the isolation of circulating tumor cells (CTCs) in the blood of patients with head and neck cancer and to determine the correlation between the presence of CTCs and early clinical outcome in these patients.

Design: prospective clinical follow-up study of patients with squamous cell carcinoma of the head and neck (SCCHN) undergoing surgical intervention, who had peripheral blood examined for the presence of CTCs.

Patients: the study population comprised 48 patients diagnosed as having SCCHN and undergoing surgical intervention.
