ACTIVITY NO. 1 Theories in Dental Caries

THEORIES OF DENTAL CARIES The legend of worm theory (EXOGENOUS THEORIES)

CORE PRINCIPLE

➔ This theory proposed that living worms inside the tooth structure were thought to be the cause of dental caries.

PROS

CONS

➔ An equivalent of which was also found in Japanese and Chinese literature ➔ India and Egypt have also accepted this theory ➔ Fumigation, acupuncture, and other treatments were aimed at the "worms."

➔ The belief that caries was caused by a "tooth worm" was no longer accepted in the medical community by the Enlightenment. ➔ Pierre Fauchard, known as the father of modern dentistry, was one of the first to reject the idea worms caused tooth decay and noted that sugar was detrimental to the teeth and gingiva.

Humoral theory (ENDOGENOUS THEORY)

➔ According to this theory, tooth decay is caused by an imbalance between the body's humors.The four humors that were thought to maintain the body health included ‘ blood, phlegm, black bile and yellow bile

➔ All diseases including dental caries attributed to imbalance between these factors.

➔ Any change in these elements' relative proportions will result in disease.

Vital theory (ENDOGENOUS THEORY)

➔ According to this theory, tooth decay started within the tooth itself.

➔ The tooth was thought to be the source and origin of the disorder, as the process began within the tooth.

➔ remained dominant until the middle of the nineteenth century.

Chemical acid theory (EXOGENOUS THEORIES)

➔ The fermentation of food particles around the teeth caused tooth decay,

➔ Responsible for caries ➔ Caries began on the enamel surface

➔ Involvement of microorganism – not recognised

where food had putrefied and gained enough dissolving power to cause the disease chemically,

Parasitic (septic) theory (EXOGENOUS THEORIES)

➔ Even though caries are purely a chemical process, microorganisms are thought to continue eliminating enamel and dentin.

➔ had recognize first the organic matrix in enamel.

➔ Neither Erdl nor Ficinus were able to explain how these organisms were able to destroy tooth structure.

Miller’s chemico-parasitic theory (ACIDOGENIC THEORY)

➔ Dental caries, according to this theory, is a chemico-parasitic process with two stages: decalcification and dissolution.

➔ Miller demonstrated through a series of experiments that certain bacteria in the mouth produce acids from carbohydrates, causing demineralization of the dental tissues. ➔ Theory that is widely accepted

➔ The evidence given by the acidogenic theory was considerable but it was not conclusive, and alternative explanation was given in the form of proteolytic theory.

Proteolytic theory (NEW THEORY)

➔ According to this theory, The organic component is the most vulnerable, followed by the inorganic, and is attacked by microorganism hydrolytic enzymes.

➔ Evidence suggests that the organic portion of the tooth is important in the development of dental caries. ➔ These structures serve as pathways for advancing microorganisms.

➔ The proteolytic theory has some minor flaws, such as a lack of evidence to support the claim that the initial attack on enamel is proteolytic.

Proteolysis chelation theory (NEW THEORY)

➔ Simultaneous microbiological degradation of organic components and mineral dissolution through the chelation process

➔ The proteolysis chelation theory addressed some of the minor flaws in the proteolytic theory.

➔ Creating conditions that make keratinous proteins less stable, as well as complexing calcium

2. What is the contribution of the different theories to our current understanding of dental caries development? Dental caries, also known as tooth decay, is a microbiologically contagious illness that affects localized dissolution and damage to the calcified structure of the teeth. Oral cancer, as well as other oral infectious diseases and, are costly to treat due to nutritional influences on craniofacial development. Despite advancements in the science of oral diseases, dental caries have become a global health concern affecting people of all ages. These dental caries theories, will make us be more careful of our oral health, examines various microbiological perspectives of dental caries in a broader sense, and its updating will aid in updating recent microbiology trends in dental caries as well as formulating various oral hygiene development programs.
