AIM: Gingivitis commonly progresses to periodontitis in permanent dentition but rarely in deciduous teeth. Little is known about the biochemical differences between gingiva of deciduous and permanent teeth. Here we compared the protein profiles of gingival crevicular fluids (GCF) from the gingiva of deciduous and permanent teeth. MATERIALS AND METHODS: Forty children with mixed dentition (Hellman's dental age IIIA) were selected and GCF samples were collected from deciduous cuspids and central incisors in the maxilla...

AIM: The bone implant contact (BIC) has traditionally been evaluated with histological methods. Thereupon, strong correlations of 2-dimensional (2D) BIC have been detected between μCT and destructive histology. However, due to the high intra-sample variability of BIC values, one histological slice is not sufficient to represent 3D BIC. Therefore, our aim has been to correlate the averaged values of 3-4 histological sections to 3D μCT. MATERIAL AND METHODS: Fifty four implants inserted into the maxilla of 14 minipigs were evaluated...

AIM: Periodontitis is a chronic inflammatory disease, characterized by irreversible destruction of tooth-supporting tissue including alveolar bone. We recently reported mucin 4 (MUC4) and matrix metalloproteinase 7 (MMP7) as highly associated with periodontitis in gingival tissue biopsies. The aim of this study was to further investigate the levels of MUC4 and MMP7 in saliva and gingival crevicular fluid (GCF) samples of patients with periodontitis. MATERIALS AND METHODS: Saliva and GCF samples were collected from periodontitis patients and healthy controls...

OBJECTIVES: Evidence on possible associations between facial morphology, attachment loss and gingival recession is lacking. We analyzed whether the facial type, which can be described by the ratio of facial width and length (facial index), is related to periodontal loss of attachment, hypothesizing that a broad face might be associated with less gingival recession (GR) and less clinical attachment loss (CAL) than a long face. MATERIALS AND METHODS: Data from the 11-years follow-up of the population-based Study of Health in Pomerania were used...
