Association between Cheiloscopic Patterns and ABO Blood Groups among South Indian Population.

BACKGROUND: Human beings have few characteristics that are unique from others. Lip prints are one of such feature. They are not changed throughout the life and are not influenced by injuries, diseases, or environmental changes. According to the various antigen-antibody reactions in the bloodstream, different individuals have specific blood groups. AIM: To study the distribution of lip print patterns among individuals with different ABO and Rh blood groups and also to know the relation between their characters and blood groups. MATERIALS AND METHODS: In the present study, lip prints were collected randomly from 85 individuals, and their blood group matching was performed. This is to identify the most common lip print type and to know any association between lip print types and blood groups. Tsuchihashi's classification of lip prints was used to compare with the ABO and Rh blood grouping systems. RESULTS: It was observed that in individuals with B+, A+, and O- blood groups, predominant pattern was Type IV and individuals having blood group O+ and AB+ common lip print pattern was Type II. CONCLUSION: This study showed strong association between lip print patterns and ABO blood groups as some blood groups were not included in statistical analysis; further studies including larger sample are essential to substantiate the results. CLINICAL SIGNIFICANCE: Correlating lip print with blood group helps in identification of the suspects. Along with lip prints, another biological record that remains unchanged throughout the lifetime of a person is the blood group. Determining the blood group of a person from the samples obtained at the site of crime and also recovering lip prints from site can help identify a person.

Sense of Coherence and Oral Health Status among 16 to 17-year-old Preuniversity Students of Virajpet Taluk: A Cross-sectional Study.

BACKGROUND: Sense of coherence (SOC) is an important psychological factor that enables people to cope with stressors and successfully maintain and improve health. Oral health affects general health and impacts quality of life. The aim of the present study is to assess the association between SOC and oral health status among 16 to 17-year-old preuniversity students in Virajpet, Karnataka, India. MATERIALS AND METHODS: A total of 361 subjects were included in the study by stratified cluster random sampling method. Sense of coherence was measured using the Kannada-translated 13-item scale proposed by Antonovsky. Oral health status was measured using oral hygiene index - simplified (OHI-S), Silness and Loe Plaque index, Community Periodontal Index (CPI) and Loss of Attachment (LA) as well as decayed-missing-filled teeth (DMFT) index. Chi-square test and analysis of variance were used to evaluate the association between SOC and oral health. RESULTS: There was no statistically significant association of plaque index and caries experience with SOC, whereas the SOC scores were found to be significantly associated with loss of attachment and OHI-S among the subjects. The distribution of the mean number of sextants with loss of attachment was more among males. CONCLUSION: Sense of coherence has a role to play in the maintenance of oral health. There is a need to closely examine the psychodynamic factors that affect oral health. CLINICAL SIGNIFICANCE: There is good evidence that SOC is a resource capable of promoting health, strengthening resilience, and developing a subjectively positive state of health.

Relationship between procrastination and academic performance among a group of undergraduate dental students in India.

Procrastination, generally defined as a voluntary, irrational delay of behavior, is a prevalent phenomenon among college students throughout the world and occurs at alarmingly high rates. For this study, a survey was conducted of 209 second-, third-, and fourth-year undergraduate dental students of Bapuji Dental College and Hospital, Davangere, India, to identify the relationship between their level of procrastination and academic performance. A sixteen-item questionnaire was used to assess the level of procrastination among these students. Data related to their academic performance were also collected. Spearman's correlation coefficient test was used to assess the relationship between procrastination and academic performance. It showed a negative correlation of -0.63 with a significance level of p<0.01 (two-tailed test), indicating that students who showed high procrastination scores performed below average in their academics. In addition, analysis with the Mann-Whitney U test found a significant difference in procrastination scores between the two gender groups (p<0.05). Hence, among the Indian undergraduate dental students evaluated in this study, it appeared that individuals with above average and average academic performance had lower scores of procrastination and vice versa.
