- Abstract
Introduction: Hypertension commonly referred to as high blood pressure is a long-term medical condition in which the blood pressure inside the arteries remains elevated. The normal blood pressure is from 120/80. There are two types of hypertension – mprimary hypertension that is due to genetics and other environmental factors such as obesity and sedentary lifestyle of the host and secondary hypertension that is due to some underlying disease such as Cushingarysyndrome, hyperthyroidism, and acromegaly. Periodontitis is the inflammation of the gums and the tissue surrounding the tooth structure. It is usually caused by bacterial accumulation due to poor oral hygiene. Periodontitis is of three types – chronic which shows a slow deterioration; aggressive which shows a rapid deterioration; and necrotizing which causes the death of gums due to improper blood supply. Moderate or severe form of periodontitis patients is said to have 20% increase in the risk of hypertension. Methodology: This cross-sectional study has taken 50 samples of individuals, who were divided into two groups – Group A and Group B each containing 25 patients. Group A consists of patients suffering from only hypertension. Group B consists of patients with both hypertension and periodontitis. The blood pressure of the patients was taken with the help of sphygmomanometer. The incidence of periodontitis was checked by the incidence of bleeding on probing. Results and Discussion: The hypertensive patients without periodontitis show a slightly dipping pH when compared to hypertensive patients with periodontitis which shows a somewhat neutral pH. Conclusion: From the study, it can be concluded that only hypertensive patients have an acidic pH when hypertensive patients are affected with periodontitis, it causes neutral pH. In addition, only periodontitis patient has a basic pH. During hypertension, the pH is low and the salivary flow rate is slow due to disturbance in the autonomic nervous system. The bicarbonate buffer is effective in high salivary flow rate and its concentration decreases during the slow rate of salivary flow – resulting in low pH. As for periodontitis, the pH is greater as the dental plaque can occur only in high pH above 7.6.
