Proteomics - The research frontier in periodontics.

Periodontitis is an inflammatory condition resulting from the interplay between the infectious agents and host factors. Various protein molecules play a vital role in the initiation, progression and severity of periodontal diseases. The study of proteins as biomarkers in periodontal diseases has been highlighted during the last few years.

Glucometric assessment of gingival crevicular blood in diabetic and non-diabetic patients: A randomized clinical trial.

Background: Diabetes mellitus is one of the most incessant metabolic afflictions with high prevalence rate in Indians. Diagnosis of diabetics in the initial stage helps to prevent its long term complications that are responsible for high morbidity and mortality. The aim of the present study was to assess whether glucometric analysis using Gingival Crevicular Blood (GCB) can be used for screening of diabetic patients in dental chair.

Host modulation therapy: An indispensable part of perioceutics.

Traditionally, only antimicrobials have been used as the chemotherapeutic modality for the treatment of periodontitis. Though bacteria are the primary etiologic factors of periodontal diseases, yet the extent and severity of tissue destruction seen in periodontitis is determined by the host immuno-inflammatory response to these bacteria. This increasing awareness and knowledge of the host-microbial interaction in periodontal pathogenesis has presented the opportunity for exploring new therapeutic strategies for periodontitis by means of targeting host response via host-modulating agents.

Periodontio-integrated implants: A revolutionary concept.

Though the fields of regenerative dentistry and tissue engineering have undergone significant advancements, yet its application to the field of implant-dentistry is lacking; in the sense that presently the implants are being placed with the aim of attaining osseointegration without giving consideration to the regeneration of periodontium around the implant. The following article reveals the clinical benefits of such periodontio-integrated implants and reviews the relevant scientific proofs. A comprehensive research to provide scientific evidence supporting the feasibility of periodontio-integrated implants was carried out using various online resources such as PubMed, Wiley-Blackwell, Elsevier etc.

Implant Maintenance: A Clinical Update.

Introduction. The differences in the supporting structure of the implant make them more susceptible to inflammation and bone loss when plaque accumulates as compared to the teeth. Therefore, a comprehensive maintenance protocol should be followed to ensure the longevity of the implant.

Diabetes history was recorded based on the information provided by the physician and it included date of diagnosis, duration, age of diagnosis, latest values of glycosylated haemoglobin and existing diabetic complications.

Essentials of periodontal medicine in preventive medicine.

Influence of systemic disorders on periodontal diseases is well established. However, of growing interest is the effect of periodontal diseases on numerous systemic diseases or conditions like cardiovascular disease, cerebrovascular disease, diabetes, pre-term low birth weight babies, preeclampsia, respiratory infections and others including osteoporosis, cancer, rheumatoid arthritis, erectile dysfunction, Alzheimer's disease, gastrointestinal disease, prostatitis, renal diseases, which has also been scientifically validated. This side of the oral-systemic link has been termed Periodontal Medicine and is potentially of great public health significance, as periodontal disease is largely preventable and in many instances readily treatable, hence, providing many new opportunities for preventing and improving prognosis of several systemic pathologic conditions.
