Method: A total of 10 mouth breathing patients were recruited for the study. They were systemically healthy except their mouth breathing problem. All patients were diagnosed for adenotonsillar hypertrophy by an ENT specialist. All have dry mouth complain when they wake up in the morning. Non of the patients were prescribed for antibiotics in the last month. The examined periodontal clinical parameters were Aproximal Plaque Index, Bleeding on probing, Probing Depth, DMF Score. The periodontal examination sites were divided into two groups according to the location of the tooth; anterior and posterior. Anterior and posterior sites’ plaque index and bleeding on probing levels were compared. Periodontal examinations were conducted by a trained dentist. Unstimulated whole saliva were collected to determine flow rate, buffering capacity.
Result: There was no significant difference in the Plaque Index and Bleeding on Pobing levels between anterior and posterior teeth (p=0.6, p=0.3 respectively). The mean salivary flow rate of the patients were 0.42ml/min. The buffering capacity of all patients were between 4-6 ml/min.
Conclusion: The effect of mouth breathing on periodontal tissues is not related to saliva buffering capacity or salivary flow rate. Anterior teeth did not show more inflammation than posterior teeth. This displays that mouth breathing effects all areas of mouth.
