BACKGROUND Hereditary gingival fibromatosis is characterized by slowly progressive enlargement of the gingiva that can present as an isolated condition or present as part of various syndromes. CASE REPORT An 11-year-old female reported with a gingival lesion that caused masticatory problems and poor oral hygiene. Periodontal examination revealed a dense tissue covering 30% of her teeth crowns within both jaws. Panoramic x-ray showed a normal bone height and teeth positioning. The patient did not use any medications, but a similar condition was also present in other family members...

OBJECTIVE: Visfatin is an adipocytokine that plays a role in regulating periodontal inflammation by as yet identified mechanisms. It has been suggested that visfatin mediates inflammation via activation of the nuclear factor-kappa B (NF-κB) and phosphatidylinositol 3-kinase (PI3k) signaling pathways which play a role in the inhibition of neutrophil apoptosis. The aim of this study was to investigate the expression of visfatin, NF-κB (NF-κB1 and NF-κB2), PI3k, tumor necrosis factor alpha (TNF-α), and interleukin-1 beta (IL-1β) in the tissue of healthy individuals and patients with periodontitis...

Gingival recession has a diverse etiology. The consequences may include gingivitis, periodontitis, and hypersensitivity. Whereas the management can include surgical treatment options, sometimes a more conservative, yet still esthetic approach may be required. The use of gingiva-colored composites provides one such alternative and can be applied to varying presentations of the problem. While surgical treatment can be successful in re-creating favorable esthetic anatomy as well as achieving accurate tissue contour in cases when minor amounts of tissue are reconstructed, long-term results vary because of the vascularity and complexity of the interdental space...

Dilaceration is a developmental disturbance characterized by the angulation of the crown or root of a permanent tooth, which is often related to trauma of primary dentition. We report a case of a dilacerated root in a maxillary central incisor associated with gingival hyperplasia in a patient under fixed orthodontic treatment, a combination of pathological conditions that had never been mentioned before in the scientific literature.A 10-year-old female patient presented to the Department of Odontology and Oral Pathology with tenderness to palpation and bleeding from the oral aspect of the central incisor, alerted by the proliferation of the gingiva...

OBJECTIVES: Gingival recession is the term used to characterize the apical shift of the marginal gingiva from its normal position on the crown of the tooth. It is frequently observed in adult subjects. The occurrence and severity of the gingival recession present considerable differences between populations. To prevent gingival recession from occurring, it is essential to detect the underlying etiology. The aim of the present study was to determine the occurrence of gingival recession and to identify the most common factor associated with the cause of gingival recession...

While, overall, dental implants are highly efficacious, consistently achieving predictable esthetic results can pose color-driven challenges at the implant/soft-tissue interface, particularly in the esthetic zone. An ongoing, 5-year, multicenter (eight sites) prospective study is following a total of 168 implants placed in 120 patients using a novel biomimetic (osteoconductive) implant system with pink collars and abutments that afford better gingival color matching, enhanced design variability, and streamlined fabrication and customization of the abutment/implant-tissue interface...

The gray values accuracy of dental cone-beam computed tomography (CBCT) is affected by dental metal prostheses. The distortion of dental CBCT gray values could lead to inaccuracies of orthodontic and implant treatment. The aim of this study was to quantify the effect of scanning parameters and dental metal prostheses on the accuracy of dental cone-beam computed tomography (CBCT) gray values using the Taguchi method. Eight dental model casts of an upper jaw including prostheses, and a ninth prosthesis-free dental model cast, were scanned by two dental CBCT devices...

Gingival fibromatosis is a rare and heterogeneous group of disorders that develop as slowly progressive, local or diffuse enlargements within marginal and attached gingiva or interdental papilla. In severe cases, the excess tissue may cover the crowns of the teeth, thus causing functional, esthetic, and periodontal problems, such as bone loss and bleeding, due to the presence of pseudopockets and plaque accumulation. It affects both genders equally. Hereditary, drug-induced, and idiopathic gingival overgrowth have been reported...

STATEMENT OF PROBLEM: The mechanical-chemical technique and the use of a laser are methods for displacing the gingiva to make an accurate impression of the preparation for a complete crown. The tissue needs to be displaced and the hemorrhage controlled to capture the prepared finishing line in the impression. The degree of undesirable gingival recession after these displacement techniques is unknown. PURPOSE: The purpose of this pilot clinical study was to clinically monitor and compare the regeneration of the gingival tissue by using 2 methods of gingival displacement in the same participant: the mechanical-chemical technique with double cords impregnated with aluminum chloride and the 810 nm diode laser (Odyssey; Ivoclar Vivadent AG)...
