INTRODUCTION: The aim of this study is to describe a case of a melanotic macule found in conjunction with a giant cell fibroma (GCF). For oral pigmented lesions without an identifiable etiologic factor, critical factors in determining the differential diagnosis are clinical history, symmetry, and uniformity of the lesions. Potential differential diagnosis includes racial pigmentation, endocrine disturbance, Peutz-Jeghers syndrome, trauma, hemochromatosis, oral malignant melanoma, or idiopathic etiology and melanotic macules...

INTRODUCTION: There exist a number of factors that affect the outcome of orthodontic treatment. These factors can be assessed by various gingival markers. One such maker is myeloperoxidase (MPO). Hence, we planned the present study to assess and compare the MPO activity in the gingival crevicular fluid (GCF) of subjects undergoing orthodontic treatment by different aligning arch wires. MATERIALS AND METHODS: The present study included assessment of patients who underwent orthodontic treatment for crowding of anterior teeth...

AIM: Periodontal diseases are associated with microorganisms rich in Gram-negative species. Several studies have indicated the presence of few a periodontopathic microorganisms in the same family. A parent with severe adult periodontitis, who is infected with bacteria associated with periodontal disease, may function as a source of infection. Their children may be at a greater risk to become colonized with bacteria. The purpose of this investigation was (1) to explore the presence of three bacteria, such as Porphyromonas gingivalis (PG), Prevotella intermedia (PI), and Aggregatibacter actinomycetemcomitans (AA) in the same Lebanese family and (2) to study the clinical destruction in the same family and their relations as members of this family due to the presence of PG...

BACKGROUND: Orthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy...

AIM: The aim of this prospective cohort study was to evaluate the postinsertion posterior single-implant occlusion changes at 3- and 6-month intervals using T-Scan computerized occlusal analysis. MATERIALS AND METHODS: A total of 21 patients received single implant, opposed by natural dentition, in posterior regions of the maxilla or mandible (13 premolar, 8 molar) and were finally restored with cemented-retained metal-ceramic crowns. The occlusal contacts were equilibrated according to the implant-protective occlusion concept to develop light contact with heavy occlusion and no contact with light occlusion in maximum inter-cuspation...
