Diagnosis of occlusal caries: Part I. Conventional methods. (1/53)
Accurate diagnosis of the presence or absence of disease is a fundamental requirement in health care. The diagnosis of non-overt occlusal decay is challenging and can be highly subjective, and its inherent uncertainties can lead to widely differing treatment decisions. The development of more sensitive, specific and reproducible diagnostic tools for occlusal surfaces would contribute greatly to more precise planning of preventive and operative therapy. The purpose of this 2-part paper is to review current knowledge concerning conventional and new diagnostic methods for occlusal caries. Part I looks at established diagnostic methods for occlusal surfaces. Conventional visual, tactile and radiographic examinations provide less-than-ideal diagnostic sensitivity. Neither fissure discolouration (black or brown) nor the use of an explorer has been shown to improve diagnostic accuracy. However, the combination of careful visual examination with optimal radiographic examination affords better diagnostic performance. The best visual indicators involve precise features associated with the presence of disease, such as opaque fissure demineralization and the presence and extent of localized breakdown of the enamel. For best results, teeth should be clean, thoroughly dry and well illuminated. Part II will examine new and emerging technologies, including the DIAGNOdent laser fluorescence device, which are being developed for the diagnosis of occlusal decay.

Accurate diagnosis of the presence or absence of disease is a fundamental requirement in health care. The diagnosis of non-overt occlusal decay is challenging and can be highly subjective, and its inherent uncertainties can lead to widely differing treatment decisions. The purpose of this 2-part paper is to review current knowledge concerning conventional and new diagnostic methods for occlusal caries. Part I looked at established methods for diagnosing occlusal decay. These methods have several limitations, particularly in their ability to diagnose early carious lesions. Part II examines new and emerging technologies that are being developed for the diagnosis of occlusal decay. Electrical conductance measurements and quantitative laser- or light-induced fluorescence represent significant improvements over conventional diagnostic methods, especially for in vitro applications and particularly with regard to sensitivity and reproducibility. Proponents of the DIAGNOdent laser fluorescence system claim that it evaluates the fluorescence that develops when laser light is incident on areas of demineralization. This noninvasive device is simple to use and provides quantitative data. Studies supporting its validity are limited but do suggest good sensitivity and excellent reproducibility. However, the DIAGNOdent system requires more scientific scrutiny. Although it offers a high rate of disease detection, it has little ability to indicate the extent of decay. In all treatment decisions, clinicians must be aware of the limitations of the diagnostic methods that have been used. Clinical judgment based on the patient s case history, visual cues, review of radiographs and probability of disease is still the most important aspect of optimum patient care. New technologies may provide supplemental information, but they cannot yet replace established methods for the diagnosis of occlusal caries. (+info)Clinical diagnosis of dental caries: a European perspective. (3/53)
The aim of this paper is to provide a broad international perspective on aspects of the RTI/UNC systematic review, to introduce relevant literature not cited, and to make recommendations for clinical practice education and research suggested by the evidence. Clinical caries diagnosis represents the foundation on which the answers to most of the consensus questions will be based. This paper highlights needs for being clear about definitions and nomenclature; understanding the importance of the concepts underlying the D1 and D3 diagnostic thresholds used widely within the RTI/UNC Review; and appreciating that the diagnostic challenge now faced by clinicians is significant and is becoming more complex as the presentation and distribution of the disease changes over time and the range of preventive and operative treatment options expands. A series of recommendations informed by the evidence are made, including a rather contentious issue for many clinicians concerning the lack of evidence supporting the continued use of a sharp explorer as a diagnostic tool for primary caries diagnosis. This practice should be discontinued as it may cause some harm to the patient and yet fails to provide a significant balancing diagnostic benefit. Finally, it is suggested that dentistry should learn from the developing evidence base in medicine on how best to disseminate the findings of reviews and promote appropriate changes in clinical practice. (+info)Clinical diagnosis of dental caries: a North American perspective. (4/53)
This paper summarizes current trends in the clinical diagnosis of occlusal caries in response to the RTI/UNC review and reflects the dilemma felt by many dentists who understand the difficulty in accurately assessing the extent and activity of pit and fissure caries in many of their patients. They are unsure if they should be aggressive in instrumenting suspicious lesions and provide small restorations, some of which may not be indicated. Alternatively, should they wait until signs are more clear-cut and provide larger restorations? Discussed here is the advantage of practicing dentists who obtain immediate false-positive feedback when they instrument a tooth with no clinical caries and false-negative feedback when a recall patient exhibits progression of an equivocal lesion. They should be encouraged to use this feedback as part of their diagnostic procedure and explain to their patients the difficulty of providing an accurate and precise diagnosis with existing tests. (+info)The diagnosis of root caries. (5/53)
The most commonly used clinical signs of root caries are visual (color, contour, surface cavitation) and tactile (surface texture) descriptions of a lesion. The traditional methods of visual-tactile diagnosis for root caries can produce a correct diagnosis but usually not until the lesion is at an advanced stage. Despite the subjectivity inherent in interpreting the clinical signs of root caries diagnosis, good to excellent inter-examiner reliability has been reported in clinical studies; however, the presence of filled surfaces dramatically enhances the agreement. When only untreated root caries is diagnosed, examiner reliability is reduced considerably. Clinicians look to diagnostic tests in the hope that they will perform better (that is, be more reliable) than clinical diagnosis and, therefore, can be used to replace clinical diagnosis. From the limited data available on diagnostic tests for root caries, tests determining the presence or absence of mutans streptococci and Lactobacilli are the most clinically helpful, producing calibrated efficiency scores exceeding 40 percent. The risk assessment approach to root caries diagnosis involves the determination of a patient's risk through the interpretation of clinical signs and the selection and application of an appropriate diagnostic test if the clinician is unsure of the diagnosis. (+info)Do we need to be concerned about dental caries in the coming millennium? (6/53)
Dental caries continues to be a pubic health problem despite claims that 50% of schoolchildren are caries-free. There are widespread variations in the prevalence of caries worldwide. Caries lesions are the clinical manifestation of a pathogenic process that may have been occurring on the tooth surface for months or years. Acid production by bacteria embedded in a biofilm termed "dental plaque" is a key aspect of the pathogenesis of dental caries; nevertheless, the ability of micro-organisms to survive in a hostile acid milieu and the influence of fluoride and additional agents on this acid tolerance receive scant attention. Study of cariogenic micro-organisms largely has been limited to observations made on them in the planktonic state; clearly dental caries is essentially a surface phenomenon, and micro-organisms behave distinctively when grown on a surface. Although significant progress has been made in our understanding of the etiology, pathogenesis, and prevention of dental caries, it still remains a scientific and clinical enigma worthy of the attention of the best scientists. (+info)Effect of a Brazilian regional basic diet on the prevalence of caries in rats. (7/53)
The aim of the present study was to determine the effect of a regional basic diet (RBD) on the prevalence of caries in the molar teeth of rats of both sexes aged 23 days. The animals were divided into six groups of 10 rats each receiving the following diets for 30 and 60 days after weaning: RBD, a cariogenic diet, and a commercial diet. The prevalence and penetration of caries in the molar teeth of the rats was then analyzed. The RBD produced caries in 37.5% of the teeth of animals fed 30 days, and in 83.4% of animals fed 60 days, while the cariogenic diet produced caries in 72.5% and 77.5% of the teeth of animals fed 30 and 60 days, respectively. Rats fed the RBD for 30 days had caries in the enamel in 38% of their teeth, 48% had superficial dentin caries, and 7.5% moderate dentin caries. The effect of the RBD did not differ significantly from that of the cariogenic diet in terms of the presence of caries in rats fed 60 days. The penetration depth of the caries produced by the RBD was the same as that produced by the cariogenic diet. Our results show that the RBD has the same cariogenic potential as the cariogenic diet. Since the RBD is the only option for the low-income population, there should be a study of how to compensate for the cariogenicity of this diet. (+info)The intra- and inter-examiner reliability of quantitative light-induced fluorescence (QLF) analyses. (8/53)
OBJECTIVE: To assess the reliability of the analysis stage of quantitative light-induced fluorescence (QLF). The QLF analysis involves subjective input from the user and this study examines the influence of this on the reproducibility of the QLF data. METHOD: QLF images were taken of 20 human molar teeth that had been previously subjected to a demineralizing solution (phosphoric acid 37%) to create artificial white spot lesions on their buccal surfaces. Following examination of the images, 16 were chosen to represent a range of lesion size and severity. Three copies were made of the images and each was allocated a different filename. 10 examiners in three centres were asked to analyse each of the 16 images on three occasions, with at least seven days between each attempt. Simple instructions describing the analysis procedure were supplied and examiners were asked to adhere to these directions. Examiners were asked to rate each of the 16 teeth on their first attempt both quantitatively (5 point scale) and qualitatively in terms of difficulty of analysis. Data reported were the delta Q at 5% threshold for each tooth on each of three attempts. RESULTS: Using ANOVA and paired t-tests to detect statistical differences, the three attempts of each examiner were used to determine intra-examiner reliability. Only one examiner (a novice at the technique) demonstrated differences between all three attempts and two demonstrated difference between one attempt. When the mean scores were compared to determine the inter-examiner reliability, only one examiner's results were statistically different when compared with two others. CONCLUSION: This study has demonstrated that the analysis stage of QLF is reliable between examiners and within multiple attempts by the same examiner, when analysing in vitro lesions. Novices at the technique should be trained before analysing experimental data. (+info)"Dental Caries Activity Tests are analytical methods used to measure the level of microbial activity in dental plaque or saliva, which can indicate the risk of tooth decay and help guide preventive treatment strategies."
Dental caries activity tests are a group of diagnostic procedures used to measure or evaluate the activity and progression of dental caries (tooth decay). These tests help dentists and dental professionals determine the most appropriate treatment plan for their patients. Here are some commonly used dental caries activity tests:
1. **Bacterial Counts:** This test measures the number of bacteria present in a sample taken from the tooth surface. A higher bacterial count indicates a higher risk of dental caries.
2. **Sucrose Challenge Test:** In this test, a small amount of sucrose (table sugar) is applied to the tooth surface. After a set period, the presence and quantity of acid produced by bacteria are measured. Increased acid production suggests a higher risk of dental caries.
3. **pH Monitoring:** This test measures the acidity or alkalinity (pH level) of the saliva or plaque in the mouth. A lower pH level indicates increased acidity, which can lead to tooth decay.
4. **Dye Tests:** These tests use a special dye that stains active carious lesions on the tooth surface. The stained areas are then easily visible and can be evaluated for treatment.
5. **Transillumination Test:** A bright light is shone through the tooth to reveal any cracks, fractures, or areas of decay. This test helps identify early stages of dental caries that may not yet be visible during a routine dental examination.
6. **Laser Fluorescence Tests:** These tests use a handheld device that emits a laser beam to detect and quantify the presence of bacterial biofilm or dental plaque on the tooth surface. Increased fluorescence suggests a higher risk of dental caries.
It is important to note that these tests should be used as part of a comprehensive dental examination and not as standalone diagnostic tools. A dentist's clinical judgment, in conjunction with these tests, will help determine the best course of treatment for each individual patient.
'Dental caries' is a multifactorial, dynamic disease process characterized by demineralization and destruction of dental hard tissues (enamel, dentin) due to bacterial acid production from fermentable carbohydrates, ultimately leading to cavitation if left untreated.
Dental caries, also known as tooth decay or cavities, refers to the damage or breakdown of the hard tissues of the teeth (enamel, dentin, and cementum) due to the activity of acid-producing bacteria. These bacteria ferment sugars from food and drinks, producing acids that dissolve and weaken the tooth structure, leading to cavities.
The process of dental caries development involves several stages:
1. Demineralization: The acidic environment created by bacterial activity causes minerals (calcium and phosphate) to be lost from the tooth surface, making it weaker and more susceptible to decay.
2. Formation of a white spot lesion: As demineralization progresses, a chalky white area appears on the tooth surface, indicating early caries development.
3. Cavity formation: If left untreated, the demineralization process continues, leading to the breakdown and loss of tooth structure, resulting in a cavity or hole in the tooth.
4. Infection and pulp involvement: As the decay progresses deeper into the tooth, it can reach the dental pulp (the soft tissue containing nerves and blood vessels), causing infection, inflammation, and potentially leading to toothache, abscess, or even tooth loss.
Preventing dental caries involves maintaining good oral hygiene, reducing sugar intake, using fluoride toothpaste and mouthwash, and having regular dental check-ups and cleanings. Early detection and treatment of dental caries can help prevent further progression and more severe complications.
The DMF (Deutscher Medizinischer Fachverlag) Index is a numerical rating system used to evaluate and compare the pharmaceutical marketing activities, promotional efforts, and communication strategies of various healthcare companies within the German-speaking market.
I'm not aware of a medical definition for "DMF Index." The abbreviation "DMF" could potentially stand for many things, as it is used in various contexts across different fields. In the field of dentistry, DMF stands for Decayed, Missing, and Filled teeth/surfaces, which is a method for measuring dental caries or tooth decay. However, there is no standard medical definition for "DMF Index." If you could provide more context or specify the field of study or practice, I would be happy to help further!
'Streptococcus mutans' is a gram-positive, facultatively anaerobic, beta-hemolytic bacterial species that naturally resides in the human oral cavity and significantly contributes to dental caries, or tooth decay, due to its ability to ferment dietary sugars into acidic byproducts.
Streptococcus mutans is a gram-positive, facultatively anaerobic, beta-hemolytic species of bacteria that's part of the normal microbiota of the oral cavity in humans. It's one of the primary etiological agents associated with dental caries, or tooth decay, due to its ability to produce large amounts of acid as a byproduct of sugar metabolism, which can lead to demineralization of tooth enamel and dentin. The bacterium can also adhere to tooth surfaces and form biofilms, further contributing to the development of dental caries.
'Dental caries susceptibility' refers to the likelihood or predisposition of an individual to develop dental caries, often influenced by factors such as diet, oral hygiene, saliva composition, and bacterial biofilm.
Dental caries susceptibility refers to the likelihood or predisposition of an individual to develop dental caries, also known as tooth decay or cavities. It is influenced by various factors such as oral hygiene practices, dietary habits, saliva composition, and the presence of certain bacteria in the mouth, particularly mutans streptococci and lactobacilli.
People with a higher dental caries susceptibility may have thinner or softer enamel, reduced saliva flow, or a greater concentration of cavity-causing bacteria in their mouths. Regular dental check-ups and good oral hygiene practices, such as brushing twice a day, flossing daily, and using fluoride toothpaste, can help reduce the risk of developing dental caries. Additionally, a balanced diet that limits sugary and starchy foods and beverages can also help lower the likelihood of tooth decay.
Saliva is a clear, watery, and slightly alkaline fluid produced by the major and minor salivary glands in the mouth, primarily consisting of water, electrolytes, various enzymes, and antibacterial compounds, which plays essential roles in food digestion, oral health maintenance, and speech.
Saliva is a complex mixture of primarily water, but also electrolytes, enzymes, antibacterial compounds, and various other substances. It is produced by the salivary glands located in the mouth. Saliva plays an essential role in maintaining oral health by moistening the mouth, helping to digest food, and protecting the teeth from decay by neutralizing acids produced by bacteria.
The medical definition of saliva can be stated as:
"A clear, watery, slightly alkaline fluid secreted by the salivary glands, consisting mainly of water, with small amounts of electrolytes, enzymes (such as amylase), mucus, and antibacterial compounds. Saliva aids in digestion, lubrication of oral tissues, and provides an oral barrier against microorganisms."
'Dental care' is the practice of maintaining and improving oral health through regular check-ups, cleanings, treatments, and education on proper hygiene to prevent dental diseases such as tooth decay and gum disease.
Dental care refers to the practice of maintaining and improving the oral health of the teeth and gums. It involves regular check-ups, cleanings, and treatments by dental professionals such as dentists, hygienists, and dental assistants. Dental care also includes personal habits and practices, such as brushing and flossing, that help prevent tooth decay and gum disease.
Regular dental care is important for preventing common dental problems like cavities, gingivitis, and periodontal disease. It can also help detect early signs of more serious health issues, such as oral cancer or diabetes, which can have symptoms that appear in the mouth.
Dental care may involve a range of treatments, from routine cleanings and fillings to more complex procedures like root canals, crowns, bridges, and implants. Dental professionals use various tools and techniques to diagnose and treat dental problems, including X-rays, dental impressions, and local anesthesia.
Overall, dental care is a critical component of overall health and wellness, as poor oral health has been linked to a range of systemic health issues, including heart disease, stroke, and respiratory infections.
