Combined assessment of lysine and N-acetyl cadaverine levels assist as a potential biomarker of the smoker periodontitis.

Periodontitis is an inflammatory condition of supporting structures of teeth leading to attachment and bone loss. Cigarette smoking is the single most important and modifiable risk factor with 5 to 20-fold susceptibility for periodontal diseases. Reverse smoking is a peculiar habit of smoking where the lit end is kept inside the mouth, which is predominant in the northern coastal districts of Andhra Pradesh. Polyamines are biologically active amines involved in tissue regeneration and modulation of inflammation. The study aimed to evaluate polyamines and check their utility as a marker in detection of periodontitis among different groups. Total polyamine levels showed significant increase in reverse smokers with periodontitis when compared to the other groups. Qualitative analysis by thin layer chromatography showed three polyamine bands with varying intensity among the different groups. Mass spectrometric and NMR analyses of the three bands identified them as N1, N8-diacetyl spermidine, N-acetyl cadaverine and lysine. Most significantly elevated levels of lysine was observed in the smoker and reverse smoker periodontitis groups when compared to healthy and non-smoker periodontitis groups. The significantly elevated levels of N-acetyl cadaverine could be responsible for the more destruction of periodontium in the reverse smoker group. Antioxidant potential decreased significantly in different smoker periodontitis groups. The present study suggests that the quantitative analysis of salivary polyamines, lysine and N-acetyl cadaverine can aid as an easy noninvasive diagnostic method for assessing the periodontal status, especially in smokers.

Evaluation of periodontal status in women with polycystic ovary syndrome versus healthy women: a cross-sectional study.

BACKGROUND: Polycystic ovary syndrome (PCOS) affects approximately 4% to 12% of females of reproductive age. Previous studies have shown an association between systemic and periodontal diseases. This study aimed to compare the prevalence of periodontal disease in women with PCOS and healthy women. METHODS: A total of 196 women aged 17 to 45 years were included in this study. Oral hygiene index-simplified (OHI-S), gingival index (GI), community periodontal index (CPI), and loss of attachment (LA) were assessed. Individuals who smoked, were pregnant, had any systemic disease (such as type 1 or type 2 diabetes mellitus, cardiovascular disease, malignancy, osteoporosis, and thyroid dysfunction), had a history of systemic antibiotic use in the past three months, or received any periodontal intervention in the past 6 months of screening were excluded. Student t-test was used to analyze the data. A p-value of <0.05 was considered statistically significant. RESULTS: Despite similar OHI-S scores (p=0.972) in the two groups, women with PCOS had significantly higher GI, CPI, and LA scores than healthy women (p<0.001). CONCLUSION: Periodontal disease was more prevalent in women with PCOS than in healthy women. This finding may be due to the synergistic effects of PCOS and periodontitis on proinflammatory cytokines. PCOS may have an effect on periodontal disease, and vice versa. Hence, education on periodontal health and early detection and intervention for periodontal diseases is of paramount importance in patients with PCOS.

Radiographic evaluation of mandibular ramus for gender estimation: Retrospective study.

BACKGROUND AND AIMS: Gender estimation is a very important part of a study in the field of anthropology and forensic sciences. In the skeleton, gender estimation is the first step of the identification process as subsequent methods for age and stature estimation are sex-dependent. Skeletal components such as the pelvis and skull are investigated for gender estimation and the mandible is a practical element to analyze sexual dimorphism in fragmented bones. The aim of the present study is to measure, compare, and evaluate various measurements of the mandibular ramus, observed in digital orthopantomographs and also to assess the usefulness of the mandibular ramus as an aid in gender estimation. MATERIALS AND METHODS: A radiographic retrospective study was conducted using 80 digital orthopantomographs to measure, compare, and evaluate the measurements of the mandibular ramus such as maximum ramus breadth, maximum ramus height, and coronoid heightusing Planmeca ProMax(®) digital machine to assess the usefulness of mandibular measurements in gender estimation. RESULTS: Descriptive statistics of various measurements and associated univariate F ratios for both the sexes were determined. Four variables were significant predictor in classifying a given sample (P < 0.001). The F-statistic values indicated that measurements expressing the greatest sexual dimorphism were noticed in the maximum ramus height. CONCLUSION: Mandibular ramus can be considered as a valuable tool in gender estimation and the most reliable measurements were obtained of linear objects in the horizontal plane by digital panoramic imaging.
