Four things are required for caries to form: a tooth surface (enamel or dentin), caries-causing bacteria, fermentable carbohydrates (such as sucrose), and time. [20] This involves adherence of food to the teeth and acid creation by the bacteria that makes up the dental plaque. [21]
Those microorganisms nearest the tooth surface typically obtain energy by fermenting dietary sucrose; during fermentation they begin to produce acids. The bacterial equilibrium position varies at different stages of formation. Below is a summary of the bacteria that may be present during the phases of plaque maturation:
Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses. Viruses that specifically infect bacteria—bacteriophages—are most common in the oral ...
Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The infection at the root of the tooth can travel through bone and infect surrounding soft tissue. Mouth infections are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. [1]
Extracellular long-chained glucans synthesized from sucrose via glucosyltransferase enzymes help accumulate S. sobrinus on tooth enamel surfaces. The glucans provide a shelter for bacterial colonization, and the protected environment creates the perfect nesting ground for S. sobrinus and other microorganisms to sustain a stable community in the form of dental plaque.
[1] [2]: 411 It can present with slightly pale, smooth or roughened surface morphology. It is caused by the human papilloma virus types 13 and 32. [3] It exhibits surface cells with vacuolated cytoplasm around irregular, pyknotic nuclei and occasional cells with mitosis-like changes within otherwise mature and well-differentiated epithelium.
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
Early childhood caries (ECC) is a multifactorial disease, with risk factors including but not limited to, cariogenic bacteria, diet practices and socioeconomic factors. [6] Deciduous teeth begin to erupt at 6 months of age, once visible in the oral cavity they are susceptible to tooth decay or dental caries. [1]
