Immunohistochemical analysis of the gingiva with periodontitis of type I plasminogen deficiency compared to gingiva with gingivitis and periodontitis and healthy gingiva.

Objective: Type I plasminogen deficiency (Plgdef) is an uncommon chronic inflammation of mucous membranes. Gingival enlargements usually proceed with progressive periodontal destruction and tooth-loss. Plasmin(ogen)-independent enzymatic mechanisms for fibrin clearance have already been discussed in the literature.

The Use of High-Frequency Ultrasound in the Measurement of Thickness of the Maxillary Attached Gingiva.

Purpose: Ultrasonography has been extensively explored in dentistry because of its several diagnostic advantages. The purpose of this study was to determine the thickness of the maxillary attached gingiva with the use of a high-frequency ultrasound in subjects with sex-, age- and smoking-related differences.

Materials And Methods: A total of 100 healthy subjects (70 women and 30 men, age range: 18 to 55 years) were included.
