CD79A and dental caries: When saliva flow is reduced, oral health problems such as dental caries and oral infections can develop.3,5 The protective function of saliva can overwhelm bacterial action, so studies indicate the importance of prevention and treatment, as is the case in other infectious diseases.2 Saliva contains antimicrobial proteins,i.e., immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM), as well as antimicrobial agents,i.e., lysozyme, prolene-rich glycoproteins, mucins, lactoferrin, and lactoperoxidases.
