Treatment of a Localized Stage III Periodontitis in the Esthetic Zone with Guided Tissue Regeneration Technique on a Heavy Smoker Patient with 12-Year Follow- up: A Case Report.

This case report exhibits a heavy smoker female patient with a localized stage III periodontitis who has been under the smoking cessation program during the pre-surgical period, followed by a strict maintenance program for the past twelve years, after being treated with guided tissue regeneration techniques and restored with zirconia prosthetic crowns. A 50-year-old, heavy smoker (> 40 cigarettes per day), systemically healthy female patient presented complaining of mobility and pain in the upper right central incisor, which was temporarily splinted to the left central incisor using resin composite. After clinical and radiographic examination, significant damage of the attachment apparatus, deep periodontal lesions extending the middle portion of the root, and severe infrabony defect were noted.

Correlations between Width of Keratinized Gingiva and Supracrestal Gingival Tissues Dimensions: A Retrospective Clinical Study.

Aim: The aim of this retrospective study is to assess potential correlation between the width of the keratinized gingiva (KG), and the dimensions of the supracrestal gingival tissue (SGT) components.

Materials And Methods: On the sample of 259 teeth of 79 patients, the following measurements were collected: width of KG, sulcus depth (SD), SGT, and biological width (BW) dimensions; separate correlations between measured elements were computed for males and females, for anterior and posterior, and for maxillary and mandibular teeth separately.

Results: Correlations between buccal KG and BW were present only for the upper anterior teeth and were nonsignificant in the female subsample, whereas the correlation between lingual KG and SGT were present only in females.

Effect of patient- and surgery-related factors on supracrestal tissue reestablishment after crown lengthening procedure.

Objectives: The standard application of a mean value of 2.04 mm for the biologic width has been demonstrated to result in inconsistent amounts of tooth extension following a crown lengthening procedure. Biologic width has been replaced by the supracrestal gingival tissue dimension, which includes the biologic width and sulcular depth.

Single Sitting Surgical Treatment of Generalized Aggressive Periodontitis Using GTR Technique and Immediate Implant Placement with 10-Year Follow-Up.

This case report exhibits a patient with generalized aggressive periodontitis who has been under maintenance for the past 12 years after being surgically treated in a single sitting and restored with dental implants. A 41-year-old systemically healthy male patient presented complaining of lower anterior teeth mobility and pain in the upper right quadrant. After clinical and radiographic examination, the upper right molars and lower anterior incisors were deemed unrestorable.

Comparison of the Clinical Biological Width with the Published Standard Histologic Mean Values.

Aims And Objectives: Biologic width (BW) as defined by Cohen is the part of the supracrestal gingival tissues that occupy the space between the base of the gingival crevice and the alveolar crest; it includes the junctional epithelium and the connective tissue element. Interactions between dental crowns and the marginal periodontal tissues analyzed in many review papers concluded that the recognition of the BW, in terms of crown margin placement, is beneficial for periodontal health. Therefore, knowledge of the dimensions of the sum of the junctional epithelium and connective tissue attachment as well as the sulcus depth (SD) is of clinical relevance.

Expression of Bone Morphogenetic Protein-2 and Histological Differentiation of Oral Squamous Cell Carcinomas.

Background and Objective : Bone morphogenic protein-2 (BMP-2) plays an essential role in mesenchymal cell differentiation into osteoblasts، through many intracellular pathways which may also be active in tumors. Invasive oral squamous cell carcinomas account for more than 90% of head and neck malignancies in many cancer registries. They are classified into three types according to epithelial cell differentiation.
