Abstract

Dental caries, a chronic disease of significant global reach, represents a leading public health problem affecting individuals across all age groups. The condition is characterized by the aggravating the loss of minerals in  dental hard tissues, primarily due to the byproducts of bacterial metabolism that are acidic in nature. Bacterial species involved in caries development include Streptococcus mutans, Streptococcus sobrinus, and several  species of Lactobacillus . These microorganisms contain unique pathogenic mechanisms that enable them to stick to tooth surfaces, convert sugars into harmful acids and then grow in acidic environments. This review analyzes the historical context and microbiology of dental caries and details the specific roles and mechanisms of Streptococcus mutans and various strains of Lactobacillus in advancement of caries. It also discusses the formation and composition of dental plaques as a significant factor in caries development, as well as the stages and symptoms of dental cavity formation. The review further explores the current treatment strategies, including antibiotics, fluoride applications, and advanced dental restoration techniques, highlighting their effectiveness and limitations in managing the prevalence of oral health problems. The comprehension of dental caries has evolved significantly; it remains a widespread problem, especially in areas with limited access to dental care. Continued investigation and innovation are crucial to developing more potent prevention and treatment methods, ultimately reducing the worldwide burden of this disease.
