Objective: Epidermal growth factor (EGF) is a polypeptide molecule, with important functions in epithelial growth and wound repair. It exerts its effects on cells by binding to receptors on the cell surface. The aim of this study was to evaluate and compare salivary EGF levels in patients with gingivitis and advanced periodontitis as well as in healthy controls.

Oral commissure contraction treatments vary from patient education to complicated surgical and/or prosthetic treatments, but recurrence is often described. This article reports on a combined surgical and non-surgical approach in order to increase maximum mouth opening and maintain the result of the surgery.

Materials And Methods: Three-dimensional finite element models were fabricated for three situations in anterior maxilla: (1) a fixture in contact with buccal cortical plate restored by straight abutment, (2) a fixture inclined at 15 degrees, and (3) 20 degrees labially restored with corresponding angled abutment. A palatal bite force of 146 N was applied to a point 3 mm below the incisal edge.
Suture needles can break when they are used to suture the oral mucosa, especially if they have been bent or if excessive force is applied. Several retrieval modalities have been discussed in the literature; these have focused mainly on locating the needle. Although the segment often is found and removed by the surgeon during the procedure, more extensive procedures and paraclinical diagnostics may be necessary.

The implants were embedded in fresh iliac bone of sheep in a 37°C water bath. Temperature changes were recorded via embedded thermocouples at the cervical (T1) and apical (T2) regions of the implant surface.

In the presence of an atrophic edentulous mandible, peri-implant soft tissue management is a challenging task. Therefore, mucosal grafts are sometimes necessary in patients with insufficient attached gingiva around abutments.
