This study will be aimed to investigated the correlation between levels of salivary amino acids (glycine , proline , lysine , alanine ) in the saliva of healthy children with and without active carious lesions and to estimate the predictive capacity of caries susceptibility

the goal of the study is to test the effect of body mass index on adolesent Iraqi student girls by measuring salivary hormones (ghrelin,leptin,resistin)and measuring oral health by plague index score() and taste perception score () 90 female subject will be enrolled in this study between 16-17 years old,30 subjects with normal body weight ,30 subject overweight ,and 30 subject with obeiece group catogerize by body mass index according to age.
the methed of the study is by taking Saliva sample from the subject , taste perception score and oral health measure.

This study aims to evaluate the changes in salivary pH and Streptococcus mutans count by preparing a solution containing these sweeteners dissolved in distilled water and administering it to the participants. Saliva samples will be collected before using the mouth rinse, and salivary pH will be measured using a pH meter, while S. mutans count will be analyzed in the laboratory.
After consuming the solution, salivary pH will be assessed at 1 minute, 15 minutes, and 30 minutes, while the growth of S. mutans will be examined 30 minutes post-rinse.
