Salivary oxidative analysis and periodontal status in children with atopy

Abstract

Background and aims: Prevalence of atopic diseases is progressively increasing in children with unclear clinical picture in oral cavity. This study aimed to find correlation between the total antioxidant and periodontal status in the saliva of periodontally compromised with atopy. Materials and methods: The groups consisted of patients of atopic diseases and gingivitis (ADG), of atopic diseases without gingivitis (AD), and healthy controls (HC). The level of gingival inflammation was evaluated using the sulcus bleeding index (SBI) reported by Mühlemann and Son. Glutathione (GSH), malondialdehyde (MDA), and superoxide dismutase (SOD) were estimated in saliva. Results: The mean salivary MDA levels of group HC was significantly lower compared with group ADG and AD (P < 0.05). Similarly, in the case of salivary GSH, marker levels revealed a significant decrease (P < 0.05) when mean values in the control group (5.12 ± 0.66 μmol/L) were compared with the ADG (2.31 ± 0.44 μmol/L) and AD groups (2.69 ± 0.56 μmol/L). The SOD activity was significantly lower in the ADG and AD groups compared with HC. Discussion: As there was no significant difference in the level of SOD concentration between groups, we suggest that antioxidant imbalance is primarily explained by atopic disease. Conclusion: The results showed changes in antioxidant balance in children with atopy.
