More than 700 bacterial species are able to colonize the subgingival periodontal pocket of humans. Periodontitis is a multi-factorial chronic inflammatory disease of the periodontium with varying degrees of bone loss. Destruction of periodontium starts by colonization of gram-negative anaerobic microorganisms. Several methods have been used for identifying the involved species. The aim of this ...

The periodontium is the supporting tissues for the tooth organ and is vulnerable to destruction, arising from overpopulating pathogenic bacteria and spirochaetes. The presence of microbes together with host responses can destroy large parts of the periodontium sometimes leading tooth loss. Permanent tissue replacements are made possible with tissue engineering techniques. However, existing peri...

The biologic width (BW) includes attached epithelial cells and connective tissue attachment complex being very important in the periodontal health during prosthetic treatments as invading this zone can cause bone resorption and gingival recession. The present study investigated biologic width values in the normal periodontium in anterior and posterior teeth. 30 patients that referred from resto...

nerve endings have been described in extracted human teeth (Griffin and Harris, Australian DJ, 19:255-59, 1974; Harris and Griffin, Australian DJ, 19:174-81, 326-37, 1974), and in mouse molars with intact surrounding periodontium (Corpron et al., J Dent Res, 53-7S, 1974; Avery et al., J Dent Res, 54:92, 1975; Corpron et al. JDentRes, 57:1B224, 1977). l)uring previous investigations of periodont...

background: surgical crown lengthening is needed for teeth with subgingival caries, fractured teeth, insufficient crown length, and deep subgingival margin of failed restorations. since there is no agreement on the effects of crown lengthening surgery on gingival parameters, the purpose of this study was to evaluate periodontal parameters in patients who needed crown lengthening surgery. method...
