Association between periodontal health and salivary mineral content

Many studies are lacking to find connection of calcium, magnesium and phosphate associated to periodontal disease. In this study the association of salivary calcium (Ca), magnesium (Mg), phosphate (P) and their ratio (Ca/Mg, Ca/P, Mg/P) with periodontal parameters among young, healthy and dentally aware subjects was evaluated. The study included 36 participants aged 27-30 years. A structured questionnaire was filled out including general information, self-report smoking and oral hygiene habits. Clinical periodontal examination was performed with graduated periodontal probe on six sites per tooth. Periodontal indexes: dental plaque (PI), supragingival calculus (SC), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) were recorded. Unstimulated saliva samples were obtained and processed for salivary minerals determination with spectrophotometry methods. Salivary flow rate was determined and pH was recorded by pH- meter. Salivary minerals, calcium, magnesium and phosphate were correlated with salivary flow and salivary pH within physiologically expected values and relations. PD correlated with lower salivary Ca/Mg ratio (p<0.05) and lower saliva phosphate concentration (r=0, 35). Higher plaque index correlated with lower salivary Ca/Mg ratio (p<0.05). BOP was greater in non-smokers and correlated with higher Ca/Mg ratio (r=0, 37). Smokers had greater mean PD, higher plaque index, and lower BOP. The present findings suggested that lower salivary phosphate concentration and Ca/Mg ratio is associated and correlates with better periodontal health. This study also confirmed that smokers compared with non-smokers have greater PD, PI and lower BOP.
