In this in vitro study, 3 experiments were conducted to evaluate the influence of customizing the apical portion on the characteristics of fiber posts. In the first experiment, 4 fiber posts were submitted to different custom adaptations (no customization, industrial shaping tool, diamond bur, or paper disc) and were observed with a scanning electron microscope to evaluate the micromorphologic changes. In the second experiment, 60 posts of different sizes were divided into 6 groups (n = 10): 0 (No. 0.5), 1 (No...

Several factors, including anomalies of shape, color, or size, or positioning of the teeth, may interfere with smile esthetics. A 26-year-old woman was dissatisfied with the esthetics of her maxillary lateral incisors, which had defective composite resin restorations with alterations of color and shape. The aim of this article is to present a step-by-step description of the technique used to fabricate esthetic restorations for the conoid maxillary lateral incisors with a minimum of dental preparation. The successful outcome demonstrates the importance of correct planning for successful restorations...

Composite resin properties can be affected by contact with gel during bleaching procedures; however, there is no consensus about the effect of this contact on resin susceptibility to color change. This study aimed to evaluate staining susceptibility and surface roughness changes in 2 composite resins (Filtek Z250 XT and Filtek Z350 XT) after application of bleaching peroxides and storage in different media. Forty-two disc-shaped specimens of each composite were made, polished, and divided into 3 groups according to treatment type (35% hydrogen peroxide, 16% carbamide peroxide, or deionized water as a control group)...

Antimicrobial photodynamic therapy (aPDT) is increasingly used in dentistry to treat a number of diseases. The procedure involves the activation of a photosensitizer by a visible light source to induce chemical reactions that create cytotoxic reactive oxygen species, cause oxidative stress, and result in inactivation of pathogenic microorganisms. The use of aPDT has been proven to reduce microorganisms present in dentin and therefore may be effective for treatment of deep caries. This case report describes the use of aPDT as an adjuvant therapy in the treatment of deep caries in the primary molar of a 7-year-old boy...

Hypohidrotic ectodermal dysplasia (HED) is a rare ectodermal disease with a systemic expression. Oral abnormalities are common and may include hypodontia and shape irregularities in the primary and permanent dentitions. Rehabilitation of the dental arches in pediatric patients with HED is a challenge because HED is a multifactorial disease that demands a complicated treatment approach and most dentists have limited experience or training in the necessary treatment. In addition, pediatric patients often lack the patience or ability to cooperate with complex prosthetic treatment...

Statins are well known for their ability to combat cardiovascular disease. There is new evidence that statins can influence a variety of cellular pathways, suggesting that their benefits may extend beyond lowering cholesterol. This review will explore potential new therapeutic roles for statins in medical and dental settings.

Mesiodentes are the most frequently encountered supernumerary teeth. Recently, reports of double mesiodens have increased, which may be due to the availability of better diagnostic methods. This article discusses 2 cases of double mesiodens with varying clinical presentations. In addition, the literature related to the etiology, clinical presentation, diagnosis, and management of mesiodentes is reviewed.

Evidence now supports the concept that the enamel on a tooth acts like a compression dome, much like the dome of a cathedral. With an overlying enamel compression dome, the underlying dentin is protected from damaging tensile forces. Disruption of a compression system leads to significant shifts in load pathways. The clinical restorative implications are significant and far-reaching. Cutting the wrong areas of a tooth exposes the underlying dentin to tensile forces that exceed natural design parameters. These forces lead to crack propagation, causing flexural pain and eventual fracture and loss of tooth structure...

The safest and least traumatic means of removing a cemented restoration is to cut a slot and pry the crown or retainer loose, sacrificing the restoration. However, various techniques and instruments for intact removal of permanently cemented cast restorations have been described in the literature. This literature review explores conservative and semiconservative techniques that are useful for preserving permanently cemented restorations during removal. Richwil resin, ultrasonic energy, and crown tractors can be considered preferred methods for removal of temporarily cemented restorations...

This case report describes computer-guided occlusal therapy in a patient who met the unified diagnostic criteria for phantom bite. After a review of the patient's medical history, along with a diagnostic work-up that included cone beam computed tomography, temporomandibular joint vibration analysis, and digital occlusal analysis, problematic dental components were discovered (including prolonged disclusion time and imbalanced bite force). A digital occlusal analyzer evaluated the patient's occlusion and systematically guided the necessary changes...

This case report describes the fabrication of 3 single crowns for a patient with weakened abutment teeth. The patient exhibited nocturnal bruxism and clenching but refused to use an occlusal appliance. The abutment teeth were endodontically treated and presented with loss of tooth structure and thin axial walls. The patient was seeking a metal-free restoration, and all-ceramic restorations were contraindicated because of the potential for abrasion of the opposing teeth and direct force transmission to the weak abutment teeth...

The purpose of this retrospective observational study was to assess success rates, both clinical and radiographic, of stainless steel crowns (SSCs) placed on primary molars using the Hall technique. A retrospective analysis was performed on recorded data of patients with any primary molar treated with an SSC that was placed using the Hall technique at the University of Iowa College of Dentistry during 2011-2015. The primary outcome measure was the success or failure of the SSCs placed with the Hall technique...

This article outlines a comprehensive, multidisciplinary strategy for treatment of patients with anorexia and bulimia nervosa. In this approach, primary medical intervention and emergency dental care are followed by the staging of treatment phases that integrate medical care, psychotherapy, nutritional counseling, and dental management, which may encompass various treatment options for repair of damaged dentition. Emphasis is placed on prevention of further tissue damage during all phases of management and following completion of the treatment course...

Ridge preservation has become a common practice to preserve the remaining alveolar bone volume after tooth extraction. The most common volume of graft material in commercially available vials is between 0.50 and 1.00 mL. The clinician must estimate how much grafting material is needed after extracting a tooth. The aim of this study is to provide the clinician with a volumetric guide for selection of graft material for ridge preservation after tooth extraction. Fifteen sets of permanent teeth, each representing a full adult dentition excluding the third molars, were selected at random from a collection of extracted teeth...

As the number of dentin desensitizing products has grown, it has become more difficult for the dental clinician to make the correct choice. This literature review seeks to clearly explain the different modes of action of current desensitizing agents, including the clinical trial outcomes of different materials and products in the market. A better understanding of the prevalence, pain physiology, diagnosis, and different methods of management of dentinal hypersensitivity is imperative for proper pain management...
