Asthmatic children were clinically examined to assess their dental caries experience and periodontal health condition. Stimulated salivary samples were collected and assessed for salivary flow rate, salivary pH and buffering capacity.

Non-asthmatic children were clinically examined to assess their dental caries experience and periodontal health condition. Stimulated salivary samples were collected and assessed for salivary flow rate, salivary pH and buffering capacity.

Caries experience of asthmatic and non-asthmatic children was recorded using the number of decayed, missing or filled teeth (dmft/DMFT) and decayed, missing or filled surface (dmfs/DMFS) indices. The gingival index (GI) was used to assess the gingival condition according to the criteria of Loe and Silness as follows: no gingival inflammation (<0.1), mild inflammation (0.1-1.0), moderate inflammation (1.1-1.9), and severe inflammation in case of marked gingival redness and edema with spontaneous bleeding and ulceration (2.0-3.0) Plaque index(PI) was used to assess the amount of dental plaque.The measurement of the state of oral hygiene by Silness-Löe plaque index is based on recording both soft debris and mineralized deposits on the following teeth: A film of plaque adhering to the free gingival margin and adjacent area of the tooth.
