An intricate balance between the periodontal tissues and the forces of occlusion, tongue, and lips helps to maintain a tooth in its physiologic position within the dental arch. Disturbances in the equilibrium can cause a tooth to migrate pathologically, often requiring multidisciplinary treatment approaches. The present case demonstrates, for the first time, the use of autologous platelet-rich plasma to aid in tooth repositioning after pathologic tooth migration. A 25-year-old woman presented with extrusion and labial migration of the maxillary left central incisor, a diastema of 3 mm, and grade II mobility...

The aim of this study was to evaluate the influence of abutments with a prosthetic index on the fracture resistance of Morse taper dental implants. Morse taper implants were divided into 2 groups (n = 5 per group): a group with an indexed implant and a nonindexed abutment (solid Morse taper universal post; WIS group), and a group with an indexed implant and an indexed abutment (WIP group). Both groups were subjected to bending tests for fracture strength until 5 mm of displacement or implant fracture occurred...

Antiphospholipid syndrome (APS) is a prothrombotic autoimmune disease that may be classified as primary or secondary. Treatment consists of oral anticoagulant, antiplatelet, and/or immunosuppressant drugs. This report describes the dental treatment of 2 women with APS and multiple dental concerns, including periodontal disease, caries, and missing teeth. The invasive dental procedures were performed in an outpatient setting with hematologic monitoring and use of local hemostatic measures. Neither interruption of anticoagulant medications nor administration of blood products was necessary...

Palatoradicular grooves (PRGs), morphologic defects that are found most frequently in maxillary anterior teeth, are predisposing factors for periodontal disease. This case report describes the successful management of a 30-year-old man who presented with advanced periodontal destruction associated with a PRG in the maxillary right lateral incisor. The treatment involved the use of a calcium phosphosilicate synthetic bone graft substitute as a periodontal regenerative material.

The prognosis of teeth with root perforations depends on several factors, including size, location, and time since occurrence. Root perforations are clinical situations that can be solved by either nonsurgical or surgical approaches. The purpose of this article is to present a case of an aggressive iatrogenic root perforation in a maxillary right central incisor solved surgically using mineral trioxide aggregate (MTA). Even in an unfavorable situation, MTA was able to induce new bone formation and reestablish gingival and periodontal health, as confirmed in follow-up examinations at 2 and 4 years...

Previous evidence has suggested that resin-modified glass ionomer cements (RMGICs) may be sensitive to temperature and moisture changes for the first 24 hours after photopolymerization. To test the hypothesis that a resin coating placed over the surface of an RMGIC restoration would decrease the susceptibility to moisture and temperature conditions, 44 RMGIC samples were prepared in inverted-cone recesses drilled in epoxy resin plates. After abrasion of all samples with 800-grit silicon carbide paper to simulate a diamond bur finish on the surface, a coat of highly filled resin was applied to the experimental group (n = 22) and cured according to the manufacturer's instructions...

This study aimed to evaluate the influence of different polishing systems on the surface roughness of composite resins following procedures to simulate the effects of toothbrushing over time. Four currently available commercial composites were used to make 128 cylindrical specimens. The specimens were randomly allocated to polishing with a 1-step polisher or 1 of 3 multistep polishers (n = 8 per group). The baseline surface roughness was measured, and the specimens were submitted to 5000, 10,000, and 20,000 brushing cycles to represent toothbrushing throughout 6, 12, and 24 months, respectively...

The aim of this study was to investigate the antimicrobial effect of an experimental adhesive system containing chitosan (0.2% and 0.5%) against Streptococcus mutans and Lactobacillus casei. Twenty-four extracted human third molars were used, and 4 cavities were prepared in each tooth. The teeth were contaminated with either S mutans (n = 12 teeth, 48 cavities) or L casei (n = 12 teeth, 48 cavities) microorganisms. One cavity in each tooth received 1 of the following treatments: negative control (no treatment [NC]), positive control (Adper Single Bond 2 [SB]), an experimental adhesive containing chitosan 0...

Prescription drug abuse is on the rise, causing detrimental health consequences and taking lives. Since dentists comprise a large percentage of opioid prescribers, they should be well educated on the uses and effects of opioids. This article discusses the consequences of long-term opioid use, how to identify signs of dependence, and how to prevent future abuse.

A middle-aged man presented for evaluation of a mixed-density lesion of the left posterior mandible. This clinicopathologic correlation presents the radiographic, clinical, and histopathologic findings; differential diagnosis; and treatment plan for this case. The lesion was deemed to be of bacteriologic origin, likely a polymicrobial infection containing actinomycetes. Clinical care and follow-up for the patient are discussed.

The purpose of this study was to evaluate the translucency and strength of highly translucent monolithic zirconia ceramic materials recently introduced to the market. Four monolithic zirconium oxide materials promoted as having high translucency (BruxZir Shaded 16, BruxZir HT, Lava Plus, and inCoris TZI C) were compared to a high-translucency, lithium disilicate monolithic glass-ceramic material (IPS e.max CAD HT). To evaluate translucency, the materials were sectioned into 0.5-, 1.0-, 1.5-, and 2.0-mm-thick specimens; all were sintered and polished...

With the advent of osseointegrated dental implant therapy in the last few decades, complete edentulism of the mandible can be treated and restored predictably and successfully. However, due to medical and financial considerations, many patients cannot avail themselves of this therapy. This article presents a case report of such a patient treated with advanced yet traditional denture construction protocols. These conventional protocols should still be considered for addressing the needs of a patient with medical or financial restrictions...

This pilot study was designed to collect initial data on overdenture attachment retention in varying configurations of attachment location in an implant-retained mandibular overdenture. A clear acrylic model of a mandible with 6 numbered implants and Locator resilient abutments was used to simulate implant placement in a patient. A clear acrylic denture was fabricated with 6 Locator housings to match the implants in the model. Attachments were tested in 4 different configurations: 2 implants, 2 and 5 (T25); 4 implants, 2-5 (T2345); 4 implants, 1, 3, 4, and 6 (T1346); and 6 implants, 1-6 (T1-6)...

A well-recognized consequence of the use of tooth whitening gels and strips, particularly prescription strength formulations, is gingival irritation and tooth sensitivity. Limited information is available in the literature on the risk of gingival chemical burns associated with over-the-counter (OTC) oral whitening rinses. This case report details the development of gingival chemical burns consequent to misuse of a whitening rinse. The affected patient had rinsed for 30 seconds daily for 3-4 days but had failed to rinse with water after usage, as specified by the manufacturer...

The purpose of this case report is to describe a previously unpublished association between focal cemento-osseous dysplasia (FCOD) and an aneurysmal bone cyst (ABC) and review the literature with regard to associated benign fibro-osseous lesions and cysts. A 41-year-old woman without a history of trauma presented with asymptomatic swelling in the right side of the mandible. Radiographs of the region revealed a unilocular radiolucent area with radiopaque foci. After aspiration of the lesion was positive for serosanguineous fluid, complete excision of the lesion was performed...
