Residual caries Residual caries is demineralised tissue left behind when a filling is placed 2 and it can be active or arrested.
Is residual caries a criterion for rerestoration?
It is concluded that although residual caries does not seem to be the criterion for rerestoration, one has to strive for as complete caries removal as possible. If this cannot be fulfilled the sealing capacities of the filling material seem to be more important than its cariostatic properties.
What are recurrent caries and how are they treated?
What are recurrent caries? Recurrent caries are caries (also commonly known as cavities) that occur underneath a dental restoration. In the case of a filling or a crown, this means that even if the previous decay that prompted the application of the crown (or filling) was removed, more decay occurred after the filling or crown.
What is the difference between recurrent and secondary dental caries?
Although recurrent caries are located underneath dental restorations, secondary caries are new caries that occur at the margins of a restoration. These are most commonly found at the places where the dental restoration meets the gumline, as in the case of a crown or a fixed denture.
Can you get recurrent caries from a tooth restoration?
Recurrent Caries And Tooth Decay. When you visit the dentist for treatment that includes dental restorations like crowns or fillings, you usually trust that the restoration has fixed the problem of caries (or cavities) in that tooth. This may not always be the case. Recurrent caries can occur after dental restoration.
What's residual caries?
Residual caries is demineralised tissue left behind when a filling is placed2 and it can be active or arrested.
What are the four main types of caries?
Removal of caries is often the result of untreated caries....Disease stagesInitial caries, caries in the spot stage or, as it is also called “white caries”. ... Superficial caries. ... Medium caries. ... Deep caries.
What causes recurrent caries?
Recurrent caries is tooth decay that occurs under existing dental restorations, such as fillings, crowns, or onlays. It may be caused by poor oral hygiene, or by development of a microscopic pathway for leakage (micro leakage) past the dental restoration.
What is difference between secondary caries and recurrent caries?
Secondary caries, otherwise known as recurrent caries (cavities) is tooth decay occurring underneath/surrounding existing dental restorations such as dental fillings, crowns or onlays.
Are caries and cavities the same thing?
Tooth decay is the disease known as caries or cavities. Tooth decay is caused by certain bacteria in the mouth that thrive on sugars and refined carbohydrates and produce acids as a side effect. The acids attach to the hard outer layer of your tooth (enamel) first.
How are dental caries removed?
Treatment options include:Fluoride treatments. If your cavity just started, a fluoride treatment may help restore your tooth's enamel and can sometimes reverse a cavity in the very early stages. ... Fillings. ... Crowns. ... Root canals. ... Tooth extractions.
What is the treatment for recurrent caries?
Clinical implications: As recurrent carious lesions are localized and limited, alternative treatments to restoration replacement are suggested. Polishing may be sufficient. If not, exploratory preparations into the restorative material adjacent to the localized defect can reveal the extent of the lesion.
Can tooth decay continue after filling?
If you've had a cavity at some point in the past and gotten it filled, you might think you're in the clear—the tooth is sealed, so nothing bad can happen to it, right? Unfortunately, tooth decay can still happen underneath a filling, especially if the filling has been cracked, worn, or otherwise damaged.
Can a dentist see decay under a filling?
Diagnosis of recurrent decay An instrument called an explorer will be used to detect worn spots around the edge of the fillings. If the seal between the filling and tooth enamel breaks down, decay-causing bacteria and food particles can get under the filling.
What is the difference between primary and secondary caries?
Primary caries is the term used to describe caries lesions developing on intact, natural tooth surfaces, as opposed to secondary or recurrent caries, which develops next to an existing restoration [Fejerskov and Kidd, 2015].
Where are you most likely to find secondary caries?
In any case, the presence or recurrence of these lesions is typically associated with the marginal areas of the restoration, and it has been stated that 80% to 90% of secondary caries will be found at the gingival margin (for class II to V restorations), irrespective of the type of restorative material (Mjör 1998, 2005 ...
Which stage is the earliest stage of dental caries?
Demineralization: The initial stage of tooth decay comes in the form of white or brown spots on the surface of the tooth. This occurs when enamel is weakened and is at risk of being stripped away. Reversing decay at this stage is possible with enamel-fortifying, remineralization toothpaste.
What are the different types of caries?
Caries can be divided into the following three types according to the location of occurrence: crown caries, root caries and mixed-type caries affecting both the crown and root.
What are the type of caries?
There are three types of smooth-surface caries. Proximal caries, also called interproximal caries, form on the smooth surfaces between adjacent teeth. Root caries form on the root surfaces of teeth. The third type of smooth-surface caries occur on any other smooth tooth surface.
What is a Class 4 cavity?
Class IV cavities Class IV carious lesions occur on the proximal surfaces of incisors and canines and involve the incisal angles.
What are the classes of caries?
Depending on its extent, decay is classified as incipient, moderate, advanced or severe. But to understand these categories, it helps to know a bit about tooth anatomy.

Patient discussion about caries
Q. Can I treat dental Caries with antibiotics? I heard it’s a contagious disease, which means there are bacteria causing it. That means I can kill them by taking antibiotics no?
What are recurrent caries?
Recurrent caries are caries (also commonly known as cavities) that occur underneath a dental restoration. In the case of a filling or a crown, this means that even if the previous decay that prompted the application of the crown (or filling) was removed, more decay occurred after the filling or crown.
What is secondary caries?
Although recurrent caries are located underneath dental restorations, secondary caries are new caries that occur at the margins of a restoration.
How are recurrent caries diagnosed?
Your dentist can diagnose recurrent caries in one of three ways (or any combination of the three).
How to tell if you have a cavity?
Recurrent caries symptoms are similar to regular cavity symptoms. They can include: 1 Tender gums that bleed easily: A sign of both cavity and gingivitis, bleeding gums in the area surrounding a dental restoration can be a first sign that excess bacteria is present and causing inflammation. 2 Sensitivity to hot and cold: Even if the dental restoration is a crown, recurrent caries can cause sensitivity to hot or cold food and drink. Some patients even experience sensitivity to food that is high in sugar. 3 Bad breath: Bad breath is another clear sign that unhealthy bacteria is present in the mouth.
Can X-rays show caries?
X-rays and other imaging devices. An X-ray can pick up recurrent caries that are not obvious from a visual or physical exam, specifically those that occur between teeth and under dental restorations. In many cases, this is the only way your dentist can diagnose recurrent caries.
Can dry mouth cause caries?
As with regular caries, poor dental hygiene is a common cause. Additionally, dry mouth can increase the chances of developing recurrent caries, as can cracked or failing dental restorations. Dental restorations that weren’t properly fitted in the first place can also lead to the development of recurrent caries.
Can caries cause sensitivity to cold?
Sensitivity to hot and cold: Even if the dental restoration is a crown, recurrent caries can cause sensitivity to hot or cold food and drink. Some patients even experience sensitivity to food that is high in sugar. Bad breath: Bad breath is another clear sign that unhealthy bacteria is present in the mouth.
What is residual caries?
Residual caries is demineralised tissue left behind when a filling is placed 2 and it can be active or arrested. It is difficult to determine what the lesion is as there is a continuum of transient changes that can either: rapidly progress, slowly progress, or not progress at all: at this point the arrested lesion becomes chronically remineralised. If the lesion is not active no treatment is required, however, when it is active treatment is required to further prevent demineralisation.
What is recurrent caries?
Recurrent caries is a primary caries lesion next to a pre-existing filling. It usually forms cervically and interproximally due to plaque stagnation. 3 Recurrent caries is potentially serious as once dentine is reached it can spread rapidly. 4 When limited to the immediate area of margin the caries can be removed and a ‘repair’ restoration can be placed.
What causes caries in teeth?
Dental caries is a reversible progressive disease of the dental tissues initiated by the action of bacteria on fermentable carbohydrates in the biofilm on tooth surfaces. 1 Streptococcus mutans and lactobacilli quickly produce acid from fermentable carbohydrates adhering to the tooth surface because of their ability to synthesise sticky extracellular polysaccharides from dietary sugar. Fermentable carbohydrates and cariogenic plaque need to be present on a tooth surface for acid to form. ‘Stephan's curve’ illustrates pH changes and shows that the gradual return of pH will result in the acid diffusing out of this plaque. This is because the saliva has a ‘buffering ability’ where calcium and phosphate fluoride enters by facilitated transport over membranes over the salivary gland tissue. Many theories have been considered into the aetiology of caries but to date it is the acidogenic theory described by Miller in the 1800s that has been proved the most likely cause. Epidemiological studies such as Tristan da Cunha in the 1930s, Hopewood House in 1942, and the Vipeholm study in 1945 all demonstrate that when refined carbohydrates are introduced into the diet at an overwhelming rate, dental caries inevitably ensues.
What is the importance of detecting and recording carious lesions?
Because of its importance, the National Dental Hygiene Board examinations require students to be proficient in detecting and classifying dental caries. So be prepared to be challenged on this topic!
Who developed the classification system for carious lesions?
Over 100 years ago, Dr. G.V. Black (1836-1915) developed a system to categorize carious lesions based on the type of tooth affected (anterior or posterior tooth) and the location of the lesion (e.g. lingual, buccal, occlusal, etc.). The six classes of carious lesions according to G.V. Black are as follows: 1
What happens when dental caries are not treated?
Dental caries worsen if you don’t get treatment. A common mistake people repeat is they believe if it doesn’t hurt, there’s no need to do anything. However, caries may progress and cause problems in the long run if you don’t tackle them right away. Complications that may occur if dental caries aren’t treated include:
What are the causes of caries?
Eating disorders: Bulimia and anorexia can contribute to the erosion of the enamel and thereby lead to caries.
What are the types of dental caries?
Not all causes of dental caries are the same. Dentists and scientists classify caries in different ways. Types of dental caries include:
Why is my tooth more susceptible to caries than enamel?
Dentin and cementum are more prone to caries than enamel due to lower mineral content. Pulpitis, a condition that causes painful inflammation of the pulp (soft area within the center of the tooth containing nerve, blood vessels, and connective tissue) Periodontitis, or gum disease.
How many children have dental caries?
According to the Centers for Disease Control and Prevention (CDC), the percentage of children aged 5-19 years with untreated dental caries is 16.9% in the United States, whereas 31.6% of adults have untreated caries. CDC also reports the total prevalence of caries (both treated and untreated) is 45.8%.
Why do caries appear on teeth?
Caries develops on enamel due to the acidic environment produced by bacteria. Acute caries: This is a rapid process affecting a large number of teeth. Lesions associated with acute caries appear grayish or light brown. Secondary caries: These occur on the edges of restoration and fracture places in the mouth.
Where do caries form?
Book now. Caries can appear in two forms called occlusal and interproximal caries. Occlusal caries form on the area on top of the tooth and are easy to spot. Interproximal caries develop in between teeth and may be unnoticed in the initial stages.
