This in vitro study sought to evaluate the sealing ability of 3 root canal obturator systems after immersion in simulated body fluid for 1 year. Specimens were divided into 3 groups (n = 10) according to the obturation manufacturer-specified system, and then immersed in simulated body fluid. This study demonstrated that the tested systems were unable to keep their sealing ability stable during the first year, and at 12 months, all 3 systems showed increased flow rates (P < 0.0001).

Research has shown that occlusal interferences affect masticatory muscle pain or dysfunction. Resolution of these problems with precise occlusal correction indicates that dental occlusion is a causative or contributory factor. However, some reports conclude that occlusion is unrelated to masticatory muscle pain or dysfunction. An explanation for this discrepancy in findings is that these nonconfirmatory studies had not documented any pretreatment or corrected occlusion. The rationale and requirements for proper occlusal splint fabrication with a verified therapeutic occlusion are presented.

There is very little information available in the dental literature concerning nonrigid removable partial denture (RPD) prostheses. As a result, the decision to use this treatment option depends on the judgment and experience of the dentist and fabricating laboratory. This article summarizes clinically pertinent information about flexible, nonrigid RPDs.

This in vitro study investigated whether permanent anterior incisors that are endodontically treated with cemented fiber-reinforced composite (FRC) posts without additional canal preparation can potentially increase the resistance to fracture and thus reduce the rate of clinical failure in root canals.The results suggest that structural support of an endodontically treated tooth (root) can be supplemented with the addition of an FRC post.

The disease processes that give rise to nodular swellings in the oral cavity include inflammatory hyperplasias, obstructive minor salivary gland disorders, infections, benign connective tissue neoplasms and salivary gland neoplasms. Understandably, the nature of these entities also varies significantly, ranging from very innocuous to aggressive lesions, underscoring the need for accurate diagnosis.

This study compared the effectiveness of 2 surgical root coverage techniques—semilunar coronally positioned flap and coronally advanced flap—using the clinical parameters of periodontal tissues from patients with Miller Class I gingival recession. Both groups showed significant reduction of plaque and gingival indices, and an improvement in clinical attachment levels and probing depth. However, results showed the coronally advanced flap technique was deemed more effective due to significant clinical attachment level gains.

This study sought to evaluate how instrumentation techniques and irrigating solutions affected the bond strength of glass fiber posts. Irrigation with 2.5% NaOCl reduced the bond strength of fiber posts significantly (P < 0.01), while CHX showed no effect (P > 0.05). It was concluded that irrigation with 2.5% NaOCl has a negative effect on micromechanical retention of glass fiber posts, whether manual or rotary instrumentation is used.

The purpose of this study was to evaluate the effects of cigarette smoke on water sorption and solubility of microfilled, microhybrid, and nanofilled composite resins. The results indicated that water sorption and solubility varied among the products, and tobacco smoke may alter the physical properties of resin-based materials.

This article presents the case of a 58-year-old woman who refused surgical treatment for a very aggressive SCC on the mandibular alveolar ridge. The site of the primary tumor (next to the bone), as well as the patient’s refusal of the proposed treatment, may have led to the hematological spread of the malignant cells, resulting in the distant metastasis.

This study compared the accuracy of impressions using 3 types of splinting materials: a pattern acrylic resin, an acrylic resin, and a dual-cured composite resin. Implant positions were compared against the master model using a coordinate measuring machine with ANOVA comparison (α = 0.05). These findings indicated that the composite resin demonstrated better accuracy than the other tested splinting materials.

This in vitro study evaluated the marginal gap, cement thickness, and microleakage of glass-ionomer cement (GIC) and phosphate monomer-containing resin cement (MDP-RC) under 2 zirconia crown systems (Cercon and DC-Zirkon). Considering the cement thickness values and microleakage scores obtained, both zirconia crown systems could be cemented in combination with either GIC or MDP-RC.

This study sought to assess the fluoride content of commercially available foods for infants 7-12 months old. All foods tested had detectable amounts of fluoride. Consuming >1 serving per day of the high fluoride concentration products in this study would place children over the recommended daily fluoride intake. Fluoride from infant foods should be taken into account when determining total daily fluoride intake.

This study used cone beam computed tomography to evaluate distances among root surfaces in molar furcations and assess the congruence between inter-root distances in molar furcations and curette blade widths. Analysis of 107 curettes revealed statistically significant differences among curette types and manufacturers. In most cases, the curettes tested allowed access for scaling and root planing of teeth with furcation involvement.

This is a case study of the replantation of an avulsed tooth (No. 9) on a 21-year-old female. The tooth was completely dislocated, yet still retained in the mouth by palatal tissue. The only treatment performed was a computed tomography scan and the patient was advised to see a dentist as soon as possible. The patient was seen by the author in his office approximately 14 hours after the initial trauma. The treatment was deemed a success 20 months post-treatment.

Radix entomolaris (RE) is the presence of an additional lingual root in mandibular molars. Though RE appears relatively infrequently, knowledge of the condition will aid in its management. This article presents 2 case reports of RE and clinical guidelines for endodontic management.

This article documents the results of a study that used a coronally advanced flap (CAF) technique with an enamel matrix protein derivative (EMD) and acellular dermis matrix (ADM) to treat Miller Class I and II recession sites. According to the 3-month results, there was significant gain in root coverage, gain in clinical attachment, and increase in width of keratinized gingiva for all recession sites treated with CAF over EMD and ADM.

Solitary median maxillary central incisor (SMMCI) syndrome is a rare dental anomaly that affects 1:50,000 live births. SMMCI syndrome is characterized by the presence of a single central incisor located on the maxillary midline in both primary and permanent dentitions. This report describes a clinical case of a 7-year-old girl with SMMCI syndrome—in addition to bilateral residual cleft and associated nasal regurgitation—that was treated with a removable maxillary obturator.

This report presents the case of an otherwise healthy patient with 12 hypertaurodontic teeth, which were detected by using cone beam computed tomography. It is essential to emphasize the importance of routine imaging examinations for diagnosing developmental dental anomalies such as taurodontism, as this condition is generally not found by routine oral examination, and is not necessarily restricted to syndromic patients.

For patients with extensive head and neck injuries due to trauma and/or who have had extensive surgical procedures, the ability to open the mouth is severely limited. This article describes an alternative method for fabricating a custom impression tray for a complete denture in patients with limited mouth opening abilities.

Osteoarthrosis is a disease that affects the temporomandibular joint. This case report chronicles the diagnosis and treatment of a patient for whom this pathological condition was accompanied by a rupture of the articular disc. A 4-month follow-up revealed remission of the articular sounds, and tissue regeneration was noted. These improvements remained visible at 5-year follow-up.

The treatment and rehabilitation of a patient with a resected mandible involves taking full advantage of all remaining structures. This is a case where crowns were placed on the remaining teeth and the remaining space was rehabilitated with an acrylic partial denture in the maxillary arch and a cast partial denture in the mandibular arch.
