Effectiveness of a web-based learning module on oral health promotion for nursing and allied health professionals

BACKGROUND Nursing and allied health professionals are helping hands for healthcare and are important in the training cascade. We aimed to develop and validate the effectiveness of a web-based learning module on oral health promotion among nursing and allied health professionals. METHODS We developed and validated an oral health module focused on prevention and promotion for a web-based intervention among nurses and allied health professionals. Pre- and post-test assessment was conducted to evaluate the effectiveness of the programme. RESULTS Of a total of 347 participants, 170 (48.9%) had a good knowledge score in the pre-test, and after attending the oral health module their number increased to 267 (76.9%). The mean difference between the pre-test and post-test scores was statistically significant (p<0.005). CONCLUSIONS Training of nurses and allied health professionals on oral health through a web-based module showed improvement in oral health literacy.

Consensus & Evidence-based INOSA Guidelines 2014 (First edition).

Obstructive sleep apnoea (OSA) and obstructive sleep apnoea syndrome (OSAS) are subsets of sleep-disordered breathing. Awareness about OSA and its consequences amongst the general public as well as the majority of primary care physcians across India is poor. This necessiated the development of the INdian initiative on Obstructive Sleep Apnoea (INOSA) guidelines under the auspices of Department of Health Research, Ministry of Health & Family Welfare, Government of India. OSA is the occurrence of an average five or more episodes of obstructive respiratory events per hour of sleep with either sleep related symptoms or comorbidities or >15 such episodes without any sleep related symptoms or comorbidities. OSAS is defined as OSA associated with daytime symptoms, most often excessive sleepiness. Patients undergoing routine health check-up with snoring, daytime sleepiness, obesity, hypertension, motor vehicular accidents and high risk cases should undergo a comprehensive sleep evaluation. Medical examiners evaluating drivers, air pilots, railway drivers and heavy machinery workers should be educated about OSA and should comprehensively evaluate applicants for OSA. Those suspected to have OSA on comprehensive sleep evaluation should be referred for a sleep study. Supervised overnight polysomnography (PSG) is the “gold standard” for evaluation of OSA. Positive airway pressure (PAP) therapy is the mainstay of treatment of OSA. Oral appliances are indicated for use in patients with mild to moderate OSA who prefer oral appliances to PAP, or who do not respond to PAP or who fail treatment attempts with PAP or behavioural measures. Surgical treatment is recommended in patients who have failed or are intolerant to PAP therapy.

Oral habits in school going children of Delhi: a prevalence study.

This study was conducted on 5554 children aged 5-13 years old with the objectives of recording the prevalence of oral habits among North Indian children according to sex. These children were selected from the schools of Delhi. The sample represented the entire school-going population of Delhi in the age group of 5-13 years. Statistical analysis was carried out using BMDP software and sex differences were calculated by using Fisher's exact test. The results showed that the prevalence of oral habits in Delhi school going children was 25.5%. Tongue thrust was the commonest habit (18.1%) followed by mouth breathing (6.6%). Thumb sucking was relatively less common habit and seen in only 0.7% of children. There were no significant differences between boys and girls for the prevalence of oral habits. However, for the specific habit types there was a sex difference. Thumb sucking was more common in girls (1.0%) when compared with boys (0.4%) and this difference was statistically significant (P < 0.001). There was a reverse trend for the mouth breathing, which was more common (P < 0.001) in boys (7.8%) than girls (5.3%). There were no differences for tongue thrust habit between boys (17.5%) and girls (18.6%).

A study of dental caries in school children from rural Haryana.

The prevalence of dental caries among rural school children (688 boys and 331 girls) in the age group of 12-16 years in Haryana was found to be 39.4%. It was 37.9% in boys and 42.6% in girls. The difference between males and females was statistically not significant. A significant increase in prevalence of dental caries with age was observed (i.e. 33.1% in 12-year-old children to 45.8% in 14-year-old children). The mean DMFT per child was found to be 1.03 and DMFT per affected child was 2.6. The mean of D, M and F was found to be 1.0, 0.03 and 0.0 respectively.

Role of messenger system in orthodontic tooth movement.

Various in vivo and in vitro studies have established that arachidonic acid metabolites i.e., prostaglandins and leukotriens play a key role in the conversion of orthodontic pressure stimuli into a cell mediated response. However, considering the different response of osteoblasts and osteoclasts to the same chemical stimuli that leads to the deposition of bone on tension side and resorption on pressure side it has been suggested that it is the messenger system that modulates the behaviour of cells. The messenger system translates a wide array of external stimuli (first messenger) in to a narrow range of internal signals (second messengers). The role of Cyclic-AMP (C-AMP), Inositol phosphate (IP3), and Diacyleglycerol (DAG) as second messengers in the mediation of orthodontic tooth movement have been discussed in this article.
