PURPOSE Previous studies have indicated that health beliefs are related to the periodontal disease status and treatment behaviour of patients. However, it is possible that treatment may affect a patient's health beliefs and thus complicate this issue. The present study therefore looked for changes in health control beliefs and oral health impacts in(More)
Expiratory resistive loads elicit compensatory reflexes in the neonate which regulate end-expiratory lung volume (EEV). This study investigated the coordination of laryngeal and diaphragmatic activities when awake neonatal lambs were exposed to a single breath expiratory resistive load. The lambs were chronically instrumented for recording trans-upper(More)
PURPOSE Previous studies have compared the use of interdental brushes and dental floss. However, none have attempted to compare their effects on subgingival plaque. Nor have smokers been excluded from previous studies, where they may have affected the assessment of gingival inflammation. MATERIALS AND METHODS The present study compared, in untreated(More)
The aim of this study was to test adjunctive insertion of 1% metronidazole gel into furcation areas during periodontal maintenance. Ten patients were selected with paired, contralateral, Class II or III furcation involvements that also bled on constant force probing. Bleeding on probing (BOP) and gingival crevicular fluid (GCF) were measured as experimental(More)
The relationship between buccolingual tooth mobility (TM) and other clinical parameters was studied in 124 upper anterior teeth in 21 patients with untreated periodontitis. Periapical long-cone radiographs were available for 74 teeth in the same population. TM was measured with Mühlemann's macroperiodontometer. Probing depths, attachment levels and bleeding(More)
