Treatment of a maxillary second premolar with an associated cystic lesion through conventional endodontic therapy combined with decompression and cyst enucleation is reported. Although cystic lesions frequently heal simply with endodontic therapy, refractory large lesions after nonsurgical endodontic treatment may require additional diagnosis and treatment. In this case, conventional root canal treatment resulted in incomplete healing and required further surgery. Following cyst enucleation with biopsy of the lesion and apical surgery on the tooth, the cause of the refractory lesion was found to be associated with foreign latex material in the periapical tissue, which was speculated to have originated from exposure to a dental glove...

It is challenging for clinicians to carry out successful periodontal therapy and maintain a full dentition in young patients with generalized bone loss of 90%. Due to advanced attachment loss and the young age of patients, fixed or removable prosthetic treatment options are compromised. Implant therapy would be complex and expensive. The presented case shows the successful conservative periodontal therapy of advanced generalized aggressive periodontitis in a 29-year-old female. A conservative approach was applied and maintained all teeth with patient satisfaction both functionally and esthetically...

The aim of this study was to evaluate long-term outcomes in a 10-year follow-up study of patients who previously completed a 3-year multicenter randomized controlled trial of immediate and early loading of dental implants with a hydrophilic and chemically active surface (SLActive) in the posterior maxilla or mandible. The patients received implants to replace at least one missing tooth, with provisional restoration on the day of surgery (immediate loading) or 28 to 34 days later (early loading). Implant survival, change in crestal bone level, and patient satisfaction were evaluated...

OBJECTIVES: To test if cigarette smoke (CS) causes discoloration of enamel, dentin, and composite resin restorations and induces color mismatch between dental hard tissues and the restorations, and to compare the findings with the effects of aerosol generated by the tobacco heating system (THS) 2.2. METHOD AND MATERIALS: Twenty-two human premolars were prepared with Class V cavities restored with Filtek Supreme Ultra (3M Espe) composite resin. Teeth were divided into two groups and exposed to either CS from 20 reference cigarettes (3R4F) or aerosol from 20 THS 2...

OBJECTIVES: Chronic kidney disease (CKD) is a public health problem worldwide. Currently, the link between oral health status, dialysis modality, and dialysis vintage is still not clear. The aim of this study was to evaluate periodontal disease, dental caries, and Candida colonization among patients under hemodialysis (HD) therapy, peritoneal dialysis (PD) therapy, and PD with previous history of HD (HD/PD). METHOD AND MATERIALS: The clinical history, smoking, and oral hygiene habits were recorded...

Acute myeloid leukemia is a bone marrow malignancy in which blasts count increases by more than 20% in the bone marrow. Allogeneic hematopoietic stem cell transplantation (alloHCT) is a treatment option for these patients with high risk of graft versus host disease (GVHD) development. Chronic GVHD (cGVHD) often mimics a variety of autoimmune conditions such as systemic lupus erythematous or systemic sclerosis. Sclerotic cGVHD has a wide spectrum of oral manifestations, including mucosal atrophy, microstomia, and hyposalivation...

OBJECTIVE: Considerable emphasis has been placed on the fear that patients undergoing oral surgery have of the local anesthetic injection. However, other potential factors such as fear of pain during the operation, fear of the operation itself, and fear of postoperative pain are often not considered. The purpose of this study was to determine how patients rank their fear of these four factors. Such information can be helpful in improving patient management. METHOD AND MATERIALS: Patients 18 years of age and older presenting to the Oral Surgery Clinic of the Virginia Commonwealth University School of Dentistry for tooth extraction were asked to complete a brief questionnaire ranking their fear of the four previously noted factors, as well as to include their age, gender, and level of education...

OBJECTIVES: To investigate the novel use of computer-aided dynamic navigation for guided endodontics. METHOD AND MATERIALS: Dental casts were fabricated from sets of extracted human teeth. A cone beam computed tomography (CBCT) scan of each cast, with a molded thermoplastic stent and a radiographic marker attached, was obtained and imported into the planning software of a dynamic navigation implant surgery system. Simulating implant surgery but for guided endodontics, the drilling entry point, angle, pathway, and depth of virtual implants were planned for 29 selected teeth...

OBJECTIVES: This systematic review aims to discuss the shaping properties and outcomes of nickel-titanium (NiTi) rotary and reciprocation systems assessed by micro-computed tomography. DATA SOURCE: A literature search was conducted in PubMed and SCOPUS database until April 2018 to identify investigations examining the shaping properties and outcomes of rotary and reciprocation NiTi systems using micro-computed tomography. In addition, a quality assessment was undertaken for the included studies...

In many areas of restorative dentistry, metal-free materials offer an alternative to metal-based restorations while ensuring high levels of biocompatibility and esthetics. Rapidly evolving CAD/CAM technology has significantly expanded the range of materials available, providing access to materials classes and their combinations not previously available within conventional manufacturing, such as zirconia ceramics and hybrid ceramics. In addition, digital methods offer previously unavailable options in diagnostics, greater planning reliability, better material quality through standardization of the manufacturing process, and reproducibility - significant benefits that can be used to advantage, especially in oral implantology...

The use of hormonal anti-inflammatory drugs is a common practice in oral and dental surgery. They have proven enhanced efficacy, increasing therapeutic success when the treatment is properly chosen and managed. However, given the complexity of neurophysiologic processes, little is known regarding the consequences of administering glucocorticoids on brain function. This article aims to bring to the attention of dental health professionals the main neurophysiologic mechanisms by which glucocorticoid hormones can affect memory and attention...

Disinfection is a crucial aspect of patient care in dentistry. In the pre-19th century era, natural elements like acids, sulfur, mercury, and various alkaline metals were valued for their ability to obliterate pathogens. More recently aerosols, sprays, and disinfectant wipes with more powerful chemicals including quaternary ammonium compounds and aldehydes have become popular. As aerosols fall out of favor due to their health and environmental risks, disinfectant wipes are becoming the most trusted form of clinical sanitization...
