Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.

[39] [40] Curettes are mainly used to remove subgingival calculus, smooth root surfaces and to clean out periodontal pockets. [39] [43] Curettes can be divided into two subgroups: universals and area specific instruments. Universal curettes can be used in multiple areas, while area specific instruments are designed for select tooth surfaces. [40]
The depth of the periodontal pockets must be recorded in the patient record for proper monitoring of periodontal disease. Unlike in clinically healthy situations, parts of the sulcular epithelium can sometimes be seen in periodontally involved gingival tissue if air is blown into the periodontal pocket, exposing the newly denuded roots of the ...
Entamoeba gingivalis from aggressive periodontal disease patient biofilm using phase contrast microscope 1000x. It is recognizable through its dense core in the middle, formed by a central point encircled by a circular halo and surrounded by bigger phagosomes inside a greyish cytoplasm.
Gingivectomy is the primary treatment method available in reducing the pocket depths of patients with periodontitis and suprabony pockets. [4] [5] In a retrospective comparison between different treatment approach to periodontitis management based on the initial and final gingival health, conventional gingivectomy was proven to be more successful in reducing pocket depths and inflammation ...
A study used e-PTFE membranes to cover surgically constructed average size bone defects in the mandibular angles of rats. Consequently, the e-PTFE membrane acted as a barrier to soft tissue and sped up bone healing, which took place between 3–6 weeks while no healing occurred in the non-membrane control group during a 22 week period. [16]
In the presence of periodontal disease, the gingival sulcus becomes a periodontal pocket and the oxidation reduction potential will decrease to low levels as the site is very anaerobic. At the same time, the gingival crevicular fluid would have increased by 147% when gingivitis is present and would have increased by up to 30-fold where ...
This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection , although commonly the latter term is applied to an infection which has spread outside the local region around ...
