The systemic theory of dental caries Ken Southward, DDS, FAGD E namel erosion and dental caries are two different processes. The former is due to acids in the oral environment. There is evidence to demonstrate that dental caries occurs when the body can no longer control the inflammatory process within the tooth.1 While acid mayFile Size: KB.

A Review of the Biological and Clinical Aspects of Radiation Caries Aim: The aim of this article is to review the clinical and biological features underlying the development and progression of radiation caries.

Background: Although radiotherapy (RT) plays an important role in the management of patients with head and. The caries continuum, the caries balance and clinical relevance. Dental caries is a disease that is manifested as a dynamic process in the mouth.

Cycles of demineralization and remineralization continue in the mouth as long as there are cariogenic bacteria, fermentable carbohydrates and saliva by: The article presents research on the acidogenic and aciduric bacteria of the mouth and their possible connection to dental caries.

A quantitative study was produced of the incidence of acidogenic and aciduric bacteria in saliva, at the site of initial enamel decalcification, and in advanced tooth decay.

Biological Features of Dental Caries. acidogenic, aciduric and cariogenic microbiological population, high numbers in the early stages of caries and in some healthy subjects; instead. the cause of the caries process, and shows features of the classic biofilm.

Biofilm formation appears to be influenced by large scale changes in protein expression over. Objective. To examine 1) the acidogenic potential (amount lactate produced per mg plaque and minute, at pH or pH ) and the aciduric potential (acidogenic potential at pH /acidogenic potential at pH ) of dental plaque and salivary sediment taken from caries-active or caries-free adults, and 2) the effect of a short-term chlorhexidine treatment on these by: 6.

Following are some of the causes that is believed to cause dental al (acid) () proposed that an unidentified “chymical agent” was responsible for caries. According to this theory, teeth are destroyed by the acids formed in the oral cavity by the putrefaction of protein which produced ammonia and was subsequently oxidized.

Etiology of dental caries 1. Etiology of Dental Caries Introduction Definition: Dental caries is a microbial disease of the calcified tissues of the teeth, characterized by demineralization of the inorganic portion and destruction of the organic substance of the tooth.

It is the most prevalent chronic disease affecting the human race. Caries risk status is linked causally with increasing plaque levels of highly-acid-tolerant, acidogenic bacteria and an increasing plaque-pH-lowering potential Thus, after a sucrose challenge, pH values in dental plaque ex vivowill be lower in caries-active patients or sites, compared with caries-free sites or patients.

Numerous reports have shown that dental sealants are safe and highly effective in preventing pit and fissure caries in primary and permanent teeth, reducing dental caries by over 70% after 2- to 3-year follow-up. 35 With regard to evidence of effectiveness, a Cochrane review found that sealants placed on the occlusal surfaces of permanent.

Dental Caries progressive initially subsurface demineralization of teeth by bacterial acid one of the most common of all diseases major cause of loss of teeth 3. Dental Caries may be considered a disease of modern civilization since prehistoric.

Early childhood caries (ECC) is the most common chronic disease among young children who are less than 71 months of age and is currently represented as a public health problem in various countries worldwide. Dental caries continues to be a major health problem in developing nations because of lack of education, awareness, and poor socioeconomic : Arzu Pinar Edem.

Plaque samples collected from caries-free and caries-prone subjects were analysed for total bacteria, the ratio of acidogenic to total organisms and t Cited by:   Dental plaque contains bacteria that are both acidogenic and aciduric.

Although many bacterial subspecies have been shown to be associated with caries, Streptococcus mutans is still believed to be the most important bacterium in the initiation and progress of this disease in combination with lactobacilli.

In the caries process, once the pH of the plaque drops below a. Tooth decay, also known as dental caries or cavities, is a breakdown of teeth due to acids made by bacteria. The cavities may be a number of different colors from yellow to black.

Symptoms may include pain and difficulty with eating. Complications may include inflammation of the tissue around the tooth, tooth loss, and infection or abscess formation.

The cause of cavities is acid Pronunciation: Caries /ˈkɛəriːz/. The understanding of the caries process and its effect on the pulp is presented in the context that caries does develop in various rates of progression.

Early in the caries process, the pulp reflects changes within lesion activity. Thus, the early pulp response is reversible. Later, the rate of caries progression is reflected by theFile Size: KB. The incomplete tables given show that oral washings from 32 patients with varying degrees of dental decay contained lactobacilli, acidogenic streptococci and oral yeasts in at least 2, 15 and 9 cases respectively.

Of tooth decay material collected from 14 of these cases 6 contained lactobacilli, 10 contained acidogenic streptococci and 4 contained oral by: of the microbial etiology of caries, novel concepts have evolved around the caries process itself. Thus, there is a growing awareness that caries lesions can be managed by non-operative interventions [Fejerskov, ; Fejerskov et al., ].

Moreover, it has been demonstrated that the ef- fect of such interventions is reflected in the clinical ap. Caries can be classified by location as pit and fissure caries, smooth surface caries or root surface caries. In my experience, pit and fissure caries are the most common type in dogs.

A patient diagnosed with caries disease can have few or many caries lesions (a clinical manifestation), and the number and extent of these lesions are measures of disease severity. Based on clinical parameters, each caries lesion may be classified as noncavitated or cavitated (Fig.

The caries process is now well-understood; much of it has been described extensively in the dental literature. Some details of the caries process remain to be unraveled, but, in general, we understand the process well enough to initiate better-targeted methods of caries prevention and intervention.

The mechanism of dental caries formation is. This book thoroughly explains the biological background of dental caries and the formation of carious lesions, providing the reader with a sound basis for understanding the role and effectiveness of different therapeutic and preventive measures.

Detailed information is presented on pathogenesis, ultrastructure, and diagnosis. the development of a caries process. The combined action of the two types of factors tips the balance towards a development of the caries process.

2 | P a g e Introduction Dental caries, a chronic communicable disease, is experienced by more than 90% of all adults in the United States.1 In recent years, reduction in caries rates have been noted – in fact 20% of the population has 60% of the of the total caries diagnoses, making some people more susceptible to theFile Size: KB.

The surgeon general’s report Oral Health in America made it clear that oral health care is broader than dental care and that a healthy mouth is more than just healthy teeth (see Box ).

The report described the mouth as a mirror of health and disease occurring in the rest of the body, in part because a thorough oral examination can detect. specific biological factor. Current scientific knowledge makes it relatively easy to refute this conclusion.

For example, the ora cavity in most humans is colonized byStreptococcus mutan, s one of the bacteria primarily responsible for caries formation.

However, not all individuals develop caries. The mere presence. Caries risk assessment – why, when and how. Introduction There has been a dramatic decline in the caries prevalence in the last 30 years, but caries treatment still remains one of the most common and important aspects of dental practice (1).

What is Early Caries. Your tooth will not suddenly develop a hole after being affected by caries; however, if plaque is left on the surface of the tooth, acid produced by Streptococcus mutans, which causes caries, will dissolve the calcium or phosphorus components of the tooth, and they will be leached out of the enamel.
