Selected salivary antioxidants and gingival health condition among a group of obese females aged 20-22 years in Baghdad, Iraq
Keywords:Key words: Obesity, gingival health, salivary antioxidants, salivary flow rate
Background: Obesity and periodontal disease are diseases of multifactorial etiology
closely related to dietary habits and sociodemographic background of the
individuals. The aim of this study was the assessment of selected salivary
antioxidants and gingival health condition among a group of obese females aged
20-22 years in comparison with normal weight females.
Materials and methods: The study group included 40 obese females, with an age
range 20-22 years old. The control group included 40 normal weight females of
the same age. Body weight was assessed by using the Body Mass Index (BMI).
Collection of unstimulated salivary samples was carried out under standardized
conditions. Plaque and gingival indices were used for recording the oral hygiene
and gingivitis. Salivary flow rate was measured then salivary samples were
analyzed to determine the concentration of salivary antioxidants (total protein and
Results: The data analysis of the present study found that the level of salivary total
protein was lower among the obese females compared to the normal weight
females with statistically highly significant difference (p<0.01), while salivary
uric acid was statistically highly significantly higher among the obese than the
normal weight females (p<0.01). Salivary analysis demonstrated that the salivary
flow rate was statistically highly significantly higher among the obese females
The mean values of plaque index and gingival index were lower among obese
females compared to the normal weight females with statistically highly
significant difference for plaque index (p<0.01).
Conclusions: The result of this research revealed that salivary antioxidant (uric acid)
and salivary flow rate were higher among obese females than normal weight
females which may play a role in protection oral tissue from oral diseases in
addition to the oral cleanliness effect.
