    Review Article
    Yerda Ozkan* and Recep Orbak
    At the best determination and the administration treatment of a patient who has a periodontology and periodontal problem based upon an evidence, the required thing is to combine the findings of clinical examinations, if required test results will be taken and the scientific data concerning to the complaint of the patient at the dentistry literature with the complaint of the patient. The purpose of this compilation is to focus on the importance of the evidence- based treatment at the better determination of the treatment choices for the periodontology patients in the 21th century that the quality has raised at every field.
    Literature Review

    In Dentistry, the mechanical tests aim to evaluate the properties and predict the behavior of dental materials, mimicking the real biological conditions and providing methods to be further used. Among the existing tests, tensile and shear tests are highlighted. However, since the 90’s, the so-called microtests appear as an alternative to those tests. The advantage of microtests is the reliability of the results. This paper aims to evaluate, through a literature review, the advantages of microtests over the conventional tests, as well as their indications for in vitro simulation of the bond strength between the dental surfaces.

    Aim: To study the effects of viscosity of oral moisturizers and residual ridge form on the retention force of maxillary complete dentures.
    Methods: Thirty-five maxillary edentulous participants were recruited. Three types of oral moisturizers with different viscosities, artificial saliva, and denture adhesive were used. These were applied between the intaglio surface of the denture and basal seat mucosa. The central incisor was loaded 45° upward to the occlusal plane. The force needed to dislodge the denture was measured using a digital force gauge. Dental impressions of the polished surfaces and intaglio surfaces of the maxillary complete dentures were obtained. Then, duplicate dentures were cast using auto polymerizing acrylic resin. The buccolingual molar residual ridge form was assessed using the dental impressions. The duplicate denture was used to measure the positional relationship of the central incisor edge, anterior residual ridge crest, and posterior border of dentures. The effect of residual ridge form on retention force was analyzed.
    Results: The gel-type oral moisturizer showed significantly greater retention than the other types (P < .05). The retention force and buccolingual molar residual ridge form were not correlated. As the ratio of the distance from the central incisor to the anterior residual ridge crest and the distance from the anterior residual ridge crest to the posterior denture border increased, retention force decreased (r = -0.352; P < .01).
    Conclusion: The results indicate that the retention force of dentures is affected by oral moisturizer viscosity and the relative position of the anterior residual ridge crest.
    Short Communication

    The supragingival plaque control need has been sustained by the concept of the periodontal disease as an opportunistic infection. This concept relies on the fact that the supragingival biofilm has been proven to be essential for the establishment of the subgingival biofilm, this opportunity arising through a retro-feeding process between the supragingival biofilm formation and maturation and the inflammatory response. Since decades, the impact of the supragingival plaque control has been recognized as an important factor to modulate the subgingival response, regarding clinical, microbiological, and immunological indicators. These studies collectively underscore the supragingival control as essential not only for prevention of periodontal disease and maintenance of therapy results but also for the treatment of periodontitis, favoring subgingival inflammation reduction as well as the stability of attachment levels. Thus, it can be concluded that an adequate supragingival control is essential for the quality of periodontal therapy, migrating from a second-plan intervention to a unique unquestionable importance.

    Derived from neural crests, the mature pulp is due to the proliferation and condensation of apical cells implicated in root lengthening. Adult cells are bound together by intercellular junctions (desmosomes and gap junctions), forming a network. They are further transported to the crown. Root lengthening is associated to tooth eruption and to vertical sliding. Composed by type I and III collagens, fibronectin, tenascin, and other non-collagenous proteins that include a series of proteoglycans, the extracellular matrix is favoring the sliding of pulp cells. A micro-vascular network differing in the root and crown, supply the blood flow. Endothelial cells, pericytes and lymphatic vessels are contributing to direct the vascular implication to pulp development. Inflammatory and immunocompetent cells are present with in the pulp, namely dendritic cells, macrophages, lymphocytes and endothelial cells. They add to the different forms of the immune response of the dental pulp implicated in the different types of programed cell death. Nerves play role in the neutrophin family, identified within the pulp. Neuromediators are released near the nerves. Stem cells issued from the pulp of permanent and deciduous teeth, from the apical papilla and from the dental follicle, contribute to pulp healing and regeneration. Sliding of the pulp cells from the apical to the coronal pulp, and later the lateral sliding due to the effects of Wnt visualized after BIO implantation, are factors implicated in the formation of reparative and reactionary dentin, and consequently to pulp healing.
