ABSTRACT
CONTEXT: Vision is the most important sense for interpreting the world and when sight is impaired, especially in childhood it can have detrimental effects on one's life. To maintain the oral health status of such group requires special approach. AIM: The aim of this study is to evaluate the impact of Braille text and verbal, oral hygiene instructions on the oral health status of visually impaired children. SETTINGS AND DESIGN: A prospective nonrandomized before and after comparison trial without any control group was conducted among 165 children aged 7-19 years residing in one of the blind schools in Delhi. MATERIALS AND METHODS: A questionnaire was developed to record the source of oral health knowledge and practices. Oral health status of the children was evaluated by recording plaque index (PI) and gingival index (GI) scores at 1, 3, and 5 months intervals. Periodic reinforcement of oral health education was performed with the help of instructions in Braille language. STATISTICAL ANALYSIS: Paired t-test and McNemar tests were used to assess the difference between the scores before and after oral health education. RESULTS: Among completely blind children, the mean difference of PI and GI score from baseline to the last evaluation was found to be 0.56 and 0.28, whereas among partially blind children, it was found to be 0.58 and 0.25, respectively. All the above values were statistically significant (P < 0.001). CONCLUSION: Visually impaired children irrespective of the degree of blindness could maintain an acceptable level of oral hygiene when taught using Braille text for instructions. However, continuous motivation and reinforcement at regular intervals are required for the maintenance of oral health status.
ABSTRACT
BACKGROUND: Occupational injuries cause major health problems, which the developed, developing, and underdeveloped nations worldwide are facing today. The present study aimed to assess dental caries, periodontal health of stone mine workers, and the relationship between wasting diseases and the years of working experience. METHODS: The study population comprised 510 men, selected based on the stratified cluster sampling procedure. Clinical oral examinations were carried out, and periodontal disease, dental caries, and wasting diseases were recorded. RESULTS: Workers were in the age group of 17-56 years; the prevalence of dental caries in the workers was found to be 74%, with a mean decayed, missing, filled teeth index of 2.89. A periodontal pocket of more than 6 mm was observed in 6% of the workers. CONCLUSION: The oral health of mine workers is in a poor state; steps should be taken so as to provide basic medical and dental care facilities.
