Summary:

Invasion of gingival tissues by bacteria is thought to be a major factor in development of periodontal lesions. Morphologic studies have revealed bacteria within the pocket epithelium, gingival connective tissues, alveolar bone, and oral epithelium. The current studies are intended to determine whether they are present in healthy and diseased tissues and to identify the microbial source. Five beagle dogs with naturally occurring periodontitis were fed a soft diet. Two quadrants of the dentition of each dog were cleaned regularly and health maintained while others were allowed to develop further disease. After 4 weeks, samples of gingiva were removed both prior to and after the animals were sacrificed by perfusion fixation attempting not to introduce microorganisms. The identical samples were examined by light and scanning electron microscopy for numbers and location of organisms. Their numbers were greater in diseased than in healthy tissues. Furthermore, the quantity was greater in samples taken prior to perfusion fixation than after such treatment, especially in the oral epithelium. The results suggest that normally there are some microorganisms present within the periodontal tissues and that their numbers are greater in diseased tissues. However, the data also indicated that significant numbers may be introduced into the tissues during sampling of unfixed tissues. J Periodontol 1990; 61:35-4].

Tobacco is a major risk factor in the development and severity of periodontal disease, as well as in the response to periodontal therapy. It is essential that methods be employed to increase awareness of the adverse effects on the oral cavity directly related to smoking, specifically the relationship between the latter and its impact on periodontal tissue.

Periodontal Response to Early Uncovering, Autonomous Eruption, and Orthodontic Aligment of Palatally Impacted Maxillary Canines
<b>Introduction:</b> The purpose of this study was to evaluate differences in periodontal status, root length, and visual assessment in patients with palatally impacted maxillary canines that were surgically exposed, allowed to erupt freely into the palate, and orthodontically aligned. <b>Methods: </b>Clinical examinations of the maxillary lateral incisors, canines, and adjacent premolars were performed on 16 patients with unilaterally impacted canines and 6 with bilaterally impacted canines treated…

Non-Surgical Periodontal Therapy: Decision Making in the 21st Century Premium Member Content

Non-Surgical Periodontal Therapy: Decision Making in the 21st Century
Non-surgical periodontal therapy is a vital part of everyday dental practice. Since the majority of periodontal therapy is performed by general dentists and dental hygienists, it is critical that clinicians have all of the requisite skills and information needed to perform these services at the highest level possible. The purpose of this presentation is to provide the latest evidence- and practice- based information on periodontal debridement and adjunctive therapies that can improve patient outcomes. Though surgical procedures may still need to be performed in some sites, the majority of inflammatory periodontal disease can be eliminated or reduced significantly using the techniques and protocols discussed in this educational segment on non-surgical periodontal therapy.
