FIG. 1. Immunodiffusion of sonicated antigens of B. intermedius and B. Ioescheii that were isolated from the family reacted with antisera to black-pigmented Bacteroides species. The wells contain the sonicate supernatant of cells from B. intermedius isolated from the younger sister (Y-Bi), the elder sister (E-Bi) and their mother (M-Bi), B. loescheii isolated from the younger sister (Y-BI), the elder sister (E-BI), and their mother (M-BI), B. loescheii (ATCC 15930), B. intermedius (20-3), and B. gingivalis (381). Troughs contain antiserum to B. gingivalis 381 (Anti-Bg), B. intermedius 20-3 (Anti-Bi), and B. loescheii (Anti-BI), respectively.

A total of five bacteriological samples from the periodontal pockets of two sisters with localized juvenile periodontitis and their mother with advanced periodontitis was studied. Gram-negative anaerobic rods were predominant in the samples. Bacteroides intermedius and Bacteroides loescheii were the most predominant species. The antigenicity and bacteriocinogenicity of these isolates were quite similar. Serum immunoglobulin G antibody levels of the subjects to gram-negative periodontopathic bacteria were measured by using the micro-enzyme-linked immunosorbent assay. The levels of antibodies to saccharolytic black-pigmented Bacteroides species were significantly higher than the levels in healthy young females.

... In Western countries, the use of toothbrushes and interdental instruments in combination has become widespread, and this has a highly preventive effect against dental caries and periodontal disease 2,6,8) . Cleaning using a toothbrush alone has been reported to remove only approximately 65% of plaque from the entire tooth surface 11) . Toothbrush bristles are unlikely to reach interdental regions. ...

... Thus, 20,000-cycle performed in this study presented two years of tooth brushing. To achieve challenging conditions for the toothbrush abrasion test, Settima was selected because the toothpaste has a great relative dentin abrasivity (RDA) value and large abrasion compared to other toothpaste 29,30) . Thus, it should be noted that toothbrush abrasion tests with other kinds of toothpaste might show different results from those in this study. ...

... Only the characteristics of keratinized gingiva width (KGW) / attached gingiva width (AGW) around natural adjacent teeth and the KMW around future implant sites have been discussed. Regarding the natural teeth, the buccal KGW/AGW is higher at the maxillary teeth than at the opposite mandibular teeth [21][22][23]. Lang and Löe [22] also reported that the maxillary facial KGW is approximately 1.0 mm wider than that of the mandible. Factors including the position of the tooth, high frenum and muscle attachments, gingival thickness (GT), gingival phenotype (GP), and gingival recession are associated with the AGW around natural teeth [24][25][26][27][28]. ...

Considering the anatomically normal connective tissue attachment pattern, a BCL of 3.0 mm may result in approximately 15% bone resorption; more than 15% bone loss would not present incidentally. ...
