| Abstract | ||
| To evaluate the effect of the x-ray on the pH of the saliva in gingivitis in compare with control group. In this study 25 patients aged between 18-35 years suffering from gingivitis, were selected, came for periodontal treatment & 10 volunteers with normal gingiva used as control group. Unstimulated Saliva collected from all patients before & after exposed to the x-ray, the salivary pH measured in both groups pre & post exposed to the x-ray. The readings showed in control group decrease in salivary pH post exposure to x-ray, analyzed by ANOVA test. There was significant difference( p- value < 0.05) in pH value pre & post exposure to the x-ray, while the readings showed in gingivitis increase in salivary pH post exposure to x-ray, analyzed by ANOVA test . There was significant difference (p- value < 0.05) in pH value pre & post exposure to the x-ray . When the salivary water exposure to the x-ray, it will analyze the following reaction: Therefore, this explains the decrease in the pH of saliva in the control group. But the calcium, phosphate & protein are high in the saliva of gingivitis patients, so the exposed of these patients to the x-ray lead to hydrolysis of salivary water to two hydroxide ions & 2 hydrogen ions. The calcium hydroxide is strong base while the carbonic acid is a weak acid, so this explains why the salivary pH increased in case of gingivitis may be reach to the 9 degree due to this strong base. pH of the saliva decreased in case of the control group while increased in case of the gingivitis. | ||
