Abstract
To determine salivary pH in patients with Laryngopharyngeal Reflux (LPR) and compare it with that of normal individuals. A cross sectional analytical study was done. Adults with LPR as determined by Reflux Symptom Index (RSI) > 13 and Reflux Finding Score (RFS) > 7 were included in LPR group. Normal healthy adult participants with Reflux Symptom Index ≤ 3 and Reflux Finding Score ≤ 2 were included in non LPR group.32 participants were included in each groups. Salivary pH was determined in all participants using a standardized pH meter. Difference in salivary pH between two groups was statistically analyzed. The mean salivary pH in LPR group was 7.43 ± 0.77 and in non LPR group 7.0 ± 0.77. There was a statistically significant difference between the mean salivary pH between the two groups as determined by p value 0.004. The results of our exploratory study showed statistically significant difference in salivary pH between LPR and non LPR group. The salivary pH in 10(31.2%) out of 32 participants in LPR group was beyond the normal range and surprisingly the value was > 7.6, which was in contrast to acidic pH that was expected as per hypothesis. The rest 68.8% in LPR group had pH in the normal range. However salivary pH as a modality for diagnosing LPR cannot be concluded from such preliminary study with a small study population. This study forms a basis for future research for the role of salivary pH in LPR with better study designs and finer modalities of pH testing.
期刊介绍：
Indian Journal of Otolaryngology and Head & Neck Surgery was founded as Indian Journal of Otolaryngology in 1949 as a scientific Journal published by the Association of Otolaryngologists of India and was later rechristened as IJOHNS to incorporate the changes and progress.
IJOHNS, undoubtedly one of the oldest Journals in India, is the official publication of the Association of Otolaryngologists of India and is about to publish it is 67th Volume in 2015. The Journal published quarterly accepts articles in general Oto-Rhino-Laryngology and various subspecialities such as Otology, Rhinology, Laryngology and Phonosurgery, Neurotology, Head and Neck Surgery etc.
The Journal acts as a window to showcase and project the clinical and research work done by Otolaryngologists community in India and around the world. It is a continued source of useful clinical information with peer review by eminent Otolaryngologists of repute in their respective fields. The Journal accepts articles pertaining to clinical reports, Clinical studies, Research articles in basic and applied Otolaryngology, short Communications, Clinical records reporting unusual presentations or lesions and new surgical techniques. The journal acts as a catalyst and mirrors the Indian Otolaryngologist’s active interests and pursuits. The Journal also invites articles from senior and experienced authors on interesting topics in Otolaryngology and allied sciences from all over the world.
The print version is distributed free to about 4000 members of Association of Otolaryngologists of India and the e-Journal shortly going to make its appearance on the Springer Board can be accessed by all the members.
Association of Otolaryngologists of India and M/s Springer India group have come together to co-publish IJOHNS from January 2007 and this bondage is going to provide an impetus to the Journal in terms of international presence and global exposure.
