Background: Chronic infectious, inflammatory, or neoplastic disorders are associated with anemia of chronic disease. Chronic inflammatory diseases such as periodontitis may contribute to masked anemia, especially in smokers. This study was aimed at verifying and comparing the efficacy of nonsurgical periodontal therapy (NSPT) for improving anemia among chronic periodontitis patients with and without the habit of smoking. Methods: Thirty systemically healthy individuals with chronic periodontitis were divided into two groups of 15 each, smokers (group A) and nonsmokers (group B). The groups were compared based on hematological parameters such as serum erythropoietin (SE) and serum ferritin (SF) levels at baseline and 3 months after NSPT for anemia evaluation. Results: The baseline SE levels in groups A and B were 11.84 and 15.19 mIU/mL (p=0.031), respectively; the corresponding levels at 3 months after NSPT were 13.00 and 17.74 mIU/mL (p=0.022). The baseline SF levels in groups A and B were 95.49 and 44.86 ng/mL (p=0.018), respectively; the corresponding levels at 3 months after NSPT were 77.06 and 39.05 ng/mL (p=0.009). Group B showed a significant increase and decrease in the SE and SF levels, respectively, at 3 months after NSPT (p=0.035 and p=0.039, respectively), whereas group A showed insignificant changes (p=0.253 and p=0.618, respectively). Conclusion: NSPT led to an improvement in anemia among chronic periodontitis patients. However, the improvement is less in smokers compared to that in nonsmokers. Furthermore, SF and SE levels might serve as effective biomarkers for assessing anemia in smokers and nonsmokers with chronic periodontitis.

Objective: This study aimed to evaluate the association between low tongue position (LTP) and the volume and dimensions of the nasopharyngeal, retropalatal, retroglossal, and hypopharyngeal segments of the upper airway. Methods: A total of 194 subjects, including 91 males and 103 females were divided into a resting tongue position (RTP) group and a LTP group according to their tongue position. Subjects in the LTP group were divided into four subgroups (Q1, Q2, Q3, and Q4) according to the intraoral space volume. The 3D slicer software was used to measure the volume and minimum and average cross-sectional areas of each group. Airway differences between the RTP and LTP groups were analyzed to explore the association between tongue position and the upper airway. Results: No significant differences were found in the airway dimensions between the RTP and LTP groups. For both retropalatal and retroglossal segments, the volume and average cross-sectional area were significantly greater in the patients with extremely low tongue position. Regression analysis showed that the retroglossal airway dimensions were positively correlated with the intraoral space volume and negatively correlated with A point-nasion-B point and palatal plane to mandibular plane. Males generally had larger retroglossal and hypopharyngeal airways than females. Conclusions: Tongue position did not significantly influence upper airway volume or dimensions, except in the extremely LTP subgroup.

Background: Tobacco consumption has become pandemic, and is estimated to have killed 100 million people in the 20th century worldwide. Some 700,000 out of 5.4 million deaths due to tobacco use were from India. The era of global modernization has led to an increase in the involvement of women in tobacco consumption in the low income and middle-income countries. Tobacco consumption by females is known to have grave consequences. Objectives: To assess: (1) the tobacco use among urban and rural women; (2) the discrepancy in the knowledge, belief and behavior towards tobacco consumption among urban and rural women in Durg-Bhilai Metropolitan, Chhattisgarh, Central India. Materials and Methods: The study population consisted of 2,000 18-25 year old young women from Durg-Bhilai Metropolitan, Chhattisgarh, Central India, from both urban and rural areas. Data were collected using a pretested, anonymous, extensive face to face interview by a female investigator to assess the tobacco use among women and the discrepancy in the knowledge, belief and behavior towards tobacco consumption among urban and rural individuals. Results: The prevalence of tobacco use was found to be 47.2%. Tobacco consumption among rural women was 54.4% and in urban women was 40%. The majority of the women from urban areas (62.8%) were smokers whilst rural women (77.4%) showed preponderance toward smokeless tobacco use. Urban women had a better knowledge and attitude towards harms from tobacco and its use than the rural women. Women in rural areas had higher odds (1.335) of developing tobacco habit than the urban women. Conclusions: Increased tobacco use by women poses very severe hazards to their health, maternal and child health, and their family health and economic well-being. Due to the remarkably complex Indian picture of female tobacco use, an immediate and compulsory implementation of tobacco control policies laid down by t he WHO FCTC is the need of the hour.

Background: Smoking tobacco is considered as a leading cause of preventable death, mostly in developing countries like India. One of the primary goals of international tobacco control is to educate smokers about the risks associated with tobacco consumption. Tobacco warning labels (TWLs) on cigarette packages are one of the most common statutory means to communicate health risks of smoking to smokers, with the hope that once educated, they will be more likely to quit the habit. Materials and Methods: The present survey was conducted to assess the effectiveness of TWLs in communicating health risks of tobacco usage among 263 adult smokers working as bus drivers in Karnataka State Road Transport Corporation (KSRTC), Mangalore, India. Information was collected on demographic details, exposure and response to health warnings on tobacco products, intention to quit and nicotine dependency. Results: The majority (79.5%) of the respondents revealed negative intentions towards quitting smoking. Nearly half of the participants had a 'low' nicotine dependency (47.5%) and 98.1% of the respondents had often noticed warning labels on tobacco packages. These health warnings made 71.5% of the respondents think about quitting smoking. Respondents who noticed advertisement or pictures about dangers of smoking had better knowledge, with respect to lung cancer and impotence as a consequence of tobacco. A higher exposure to warning labels was significantly associated with lower nicotine dependency levels of smokers among the present study population. A significantly higher number of respondents who noticed advertisement or pictures about the dangers of smoking thought about the risks of smoking and were more inclined to think about quitting smoking. As exposure increased, an increase in the knowledge and response of participants was also observed. Conclusions: Exposure to tobacco warning labels helps to educate smokers about health risks of tobacco smoking. It may be possible to promote oral health among bus drivers by developing strategies to educate them about these risk factors.

It is a trend that carbonated drink intake among adolescents is increasing, which makes young people more vulnerable to dental erosion. However, in Korea, public knowledge about dental erosion is very insufficient. The aim of this study was to investigate the prevalence of dental erosion and to assess its risk indicators among 13-15 years old students in Yangsan, Korea. A total of 1,371 adolescents were examined by one calibrated clinician. Dental erosion was assessed by using the Visual Erosion Dental Examination system. Correlation between their dietary habit, oral hygiene and dental erosion was assessed. The data showed that 676 (49.3%) adolescents had dental erosion. The prevalence of dental erosion was significantly higher in females than in males. The prevalence of tooth erosion in mandible is higher than in maxilla. Dental erosion was generalized to develop mostly on anterior teeth, especially lateral incisor, however, the severity score was highest in canines. Following questionnaire analysis, dental erosion was significantly associated with milk and flavored milk. No other associations were detected. The prevalence of dental erosion in this study is higher than those of previous reports. On the contrary to previously reported studies, the prevalence of dental erosion in females is higher than in males.

Background: Use of smoke-less tobacco (SLT) is very common in South and South-East Asian countries. It is significantly associated with various types of cancers. The objectives of this study were to assess the proportion of hospital staff that use SLT, and to identify the factors associated with its use and their practices. Methods: In a cross-sectional study, 560 staff of two tertiary care hospitals were interviewed in the year 2009. Nurses, ward boys and technicians were counted as a paramedic staff while drivers, peons, security guards and housekeeping staff were labeled as non-paramedic staff. SLT use was considered as usage of any of the following: betel quid (paan) with or without tobacco, betel nuts with or without tobacco (gutkha) and snuff (naswar). Results: About half (48.6%) of the hospital staff were using at least one type of SLT. Factors found to be statistically significant with SLT were being a male (OR=2.5; 95% CI=1.8-3.7); having no/fewer years of education (OR=1.7; 95% CI=1.2-2.4) and working as non-paramedic staff (OR=2.6; 95% CI=1.8-3.8). Majority of SLT users were using it on regular basis, for > 5 years and keeping the tobacco products in the oral cavity for >30 minutes. About half of the users started due to peer pressure and had tried to quit this habit but failed. Conclusion: In this study, about half of the study participants were using SLT in different forms. We suggest educational and behavioral interventions for control of SLT usage.
