The trimeric model: a new model of periodontal treatment planning.

Treatment of periodontal disease is a complex and multidisciplinary procedure, requiring periodontal, surgical, restorative, and orthodontic treatment modalities. Several authors attempted to formulate models for periodontal treatment that orders the treatment steps in a logical and easy to remember manner. In this article, we discuss two models of periodontal treatment planning from two of the most well-known textbook in the specialty of periodontics internationally.

Expression of cyclooxygenase-2 (COX-2) in colorectal adenocarcinoma: an immunohistochemical and histopathological study.

Background: The aim of this study was to evaluate cyclooxygenase-2 (COX-2) immunoreactivity in colorectal adenocarcinomas and to find correlations with different pathological features.

Materials And Methods: This study included 35 cases of colorectal carcinoma for which surgical colectomy specimens were collected. Immunohistochemical staining of COX-2 (cyclooxygenase-2) is done by using the Streptavidin-biotin technique.

Immunohistochemical expression of p16 in Carcinoma Ex-pleomorphic Adenoma (undifferentiated and Adenocarcinoma Types).

Objective: This study was aimed at characterizing alterations in the immunohistochemical expression of p16 in carcinoma ex-pleomorphic adenomas.

Study Design: A selected series of 27 cases of carcinoma ex-pleomorphic adenomas were examined.

Results: The results showed that p16 expression in non tumour duct cells was strongly positive nuclear staining in 23 (85%) cases out of 27 cases, that 3 (11.

Prevalence of archaea in chronic periodontitis patients in an Indian population.

Aim: The aim of this study was to investigate the prevalence of archaea in the subgingival crevices of patients with chronic periodontitis in an Indian population.

Materials And Methods: Thirty four chronic periodontitis patients and 16 healthy subjects were included in the study. Thirty four subgingival plaque samples were collected from chronic periodontitis patients, of which 17 samples were from deep pockets and 17 were from shallow pockets.

The effect of dietary habits on the development of the recurrent aphthous stomatitis.

Background: The aim was to assess the relationship between the dietary habits and development of recurrent aphthous stomatitis.

Materials And Methods: Two groups (30 patients with RAS who have been following dietary habits and not associated with systemic disease or hematologic abnormalities, and the control group consist of 28 patients without recurrent aphthous stomatitis).

Results: A Mann-Whitney test (P>0.
