Background:A variety of oral mucosal lesions and conditions are associated with the habit of smoking and chewing tobacco, and many of these carry a potential risk for the development of cancer. There have been no studies that report the prevalence of habits and associated oral changes in the population in Dharwad region, of Karnataka, south India.Materials and Methods:A hospital–based, cross-sectional study was carried out at SDM Dental College (Dharwad, Karnataka). A total of 2400 subjects (1200 subjects with and 1200 subjects without habits) attending the dental hospital were interviewed and examined by trained professionals to assess any oral mucosal changes.Results:Oral mucosal lesions were found in 322 (26.8%) subjects who had tobacco smoking and chewing habits as compared to 34 (2.8%) subjects without those habits. Oral leukoplakia (8.2%) and oral submucous fibrosis (OSF) (7.1%) were the prevalent oral mucosal lesions found in subjects who had those habits, while the other lesions (1.7%) namely; oral candidiasis, median rhomboid glossitis, recurrent apthous ulcer, frictional keratosis, and oral lichen planus (0.9%) were frequently reported among individuals without those habits. The odds of developing oral lesions in subjects with tobacco habits was nearly 11.92 times that of abstainers (odds ratio, OR = 11.92, 95% confidence intervals, CI = 10.61-14.59%).Conclusion:The study showed that the risk of the development of oral lesions associated with tobacco smoking, chewing, or both is quite high. Males who had one or more of these habits showed more frequent oral changes than females. The study reinforces the association of OSF with gutkha and areca nut chewing, and leukoplakia, erythroplakia, and oral cancer with tobacco smoking, chewing, or mixed habits.

Objective:This study was undertaken to evaluate the respective effectiveness of the horizontal scrub, Fones, and modified Bass methods demonstrated on the cast to individual child within the classroom setting.Materials and Methods:A total of 180 healthy children studying in 1st and 2nd grades in the age range of 6-8 years were randomly selected from various schools of Gulbarga district, Karnataka, India. They were equally divided into three groups. Children in each group were demonstrated only one of the three brushing techniques, viz. horizontal scrub technique to group A, Fones technique to group B, and modified Bass technique to group C, using a cast model. All the children were re-examined and reviewed after 24 h and plaque index was re-assessed to obtain the follow-up data. The results were compared with the baseline data, and statistical analysis was carried out using paired t-test and intergroup comparison was made using analysis of variance (ANOVA) test.Results:Statistically significant (P < 0.001) reduction in plaque score was seen in modified Bass technique followed by horizontal scrub technique and the least efficacy was seen in Fones technique.Conclusion:This study showed that modified Bass technique was the most effective brushing technique in children.

Objectives:The gingival and periodontal changes during pregnancy are well known. Gingivitis is the most prevalent oral manifestations associated with pregnancy. The hormonal and vascular changes that accompany pregnancy are known to exaggerate the inflammatory response to the local irritants. Hence, a study was designed to assess oral hygiene status, gingival status, periodontal status, and treatment needs (TNs) among pregnant and nonpregnant women.Materials and Methods:A cross-sectional study was conducted among 120 pregnant and 120 nonpregnant women of 18–44 years age attending the Outpatient Department of Gynaecology and Obstetrics in Government Hospital of Belgaum city, Karnataka, India. The study consisted of an interview and oral examination. Type 3 examination was followed. Simplified Oral Hygiene Index (OHI-S), Gingival Index, and Community Periodontal Index and TNs Index were used to assess “oral hygiene status,” “gingival status,” and “periodontal status and TNs,” respectively.Results:The pregnant women showed poor oral hygiene with the mean OHI-S score as 2.68. Gingivitis was prevalent in almost all the pregnant and nonpregnant women. However, it was found more severe in pregnant women with mean gingival score as 1.25. A definite increase in gingivitis was found from Trimester II to Trimester III. The mean number of sextants showing healthy gingiva was significantly (P < 0.01) lower among pregnant women.Conclusions:Pregnant women showed poor oral hygiene, more gingival inflammation, and more periodontal disease as compared to nonpregnant women. The severity of gingivitis increased in Trimester III. Proper oral hygiene practice can prevent these diseases and further complications.
