RESUMO
Background: Saliva is complex fluid maintaining microbiological flora and oral hygiene. It has varying composition and has diagnostic and prognostic value. The present case-control study was aimed at finding the association between salivary pH and periodontal disease. Materials and methods: Three groups consisting of persons with healthy gingiva, persons with generalized chronic gingivitis and those with generalized chronic periodontitis were studied. Results: It was seen that the saliva of patients suffering from chronic generalized gingivitis was alkaline in nature while that of patients with chronic generalized periodontitis was acidic when compared with health individuals. The difference between the groups was significant (p=0.00). Conclusion: Salivary pH can have prognostic value for periodontal disease.
RESUMO
Many patients undergo orthodontic treatment for aesthetic improvement. It is well established that the patients who undergo orthodontic treatment have a high susceptibility to present plaque accumulation on their teeth because of the presence of brackets, wires and/or other orthodontic elements on the teeth surfaces with which the oral hygiene procedures might be more difficult. The orthodontic treatment is a double-action procedure regarding the periodontal tissues which may be very meaningful in increasing the periodontal health status and may be a harmful procedure which can be followed by several types of periodontal complications. There is a strong correlation between the severity and extent of gingival recessions and the orthodontic treatment suggesting that orthodontic tooth movement may lead to gingival recession. The principal objective in the treatment of gingival recession is to cover the exposed root surfaces to improve aesthetics and to reduce hypersensitivity. Different soft tissue grafting procedures have been proposed in the treatment of gingival recessions. Free gingival graft is a reliable method for treatment of gingival recession. The purpose of this case report was to illustrate the relationship between orthodontic therapy and gingival recession and to describe the management of this case.
