Basic amino acid in the pathogenesis of caries
Abstract:
Amino acid pattern in total saliva was studied in 43 children with caries, aged 12-15 years, using the method of ion exchange chromatography. The results were compared to those obtained in a control group of 39 children without caries. In saliva from the children with caries, a significantly lower level of arginine (22.02 mumol/l), and a complete lack of histidine and its derivatives were observed when compared to the control group, where the concentrations of arginine and 1-methylhistidine were 28.36 and 26.34 mumol/l, respectively. The results obtained suggested that a decreased concentration of arginine, and a lack of histidine and its derivatives might imply an increased risk of caries.

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
