DISCUSSION
Caries is aninfective disease that presents high incidence from the earliest ages and causes tooth structure loss, damaging the individual’s oral and general health. Typically, when the dentin is taken chance and it is difficult to control biofilm formation on the lesion, it is essential to remove the tissue involved to control the development of the disease (Correa et al., 2007).
During the invasive treatment of caries using high speed instruments, the dental surgeon is forced to destroy the sound tooth structure. The concept of minimally invasive dentistry is based on removing caries with method that minimize the loss of sound enamel and dentin (Allen et al., 2005). Carious dentin is composed of an outer infected layer that …show more content…

However, it is a time-consuming methodology with unclear aspects, such as the partial volumetric effect (Jan, 2006). Occurring when a single pixel or voxel includes both the structure of interest and the background, this effects results in differences in relation to successive longitudinal scans of the same specimen. As a result of this, in carious teeth specimens with larger cavities will face further suffering from partial volumetric effect in comparison to teeth with smaller cavities (Jorgensen et al., 2008). What is more, owing to the fact that the device is very expensive and limited in terms of availability due to the use of such synchrotron sources, it is not used on a widespread basis (Sidky et al., …show more content…

Knoop and Vicker’s microhardness is suitable for determining the hardness of very brittle materials, such as dental hard tissue (Hosoya et al., 2000; Hossain et al., 2003; Correa et al., 2007).
In tooth hardness studies the Vicker indenter is more practical than the Knoop’s in that a square shape has to be forever preserved; and close to the outer surface and the dentinoenamel junction a small tension of the diagonals of the indentations, that cause errors in hardness measurements, is easily determined (Gutierrez-Salazar and Reyes-Gasga, 2003). Therefore in this study, the use of a microhardness tester with a Vicker indenter allowed measuring the hardness of the remaining dentin, as an indicator of treatment effectiveness.
The mean Vicker’s hardness values of the sound dentin (VHN=55,33 in the conventional group and VHN=54,81 in the hand excavation group) in our experiment was close to the traditional Vicker’s hardness values of sound dentin (50-60 VHN) as reported by Fuentes et al. (2003). Statistical analysis did not show significant differences between the two groups for dentin

Dental assistants’ contribution to the doctor is to allow for efficient dental treatment by preparing the patient for the procedure, sterilizing instruments, passing instruments during the procedure, holding suction devices, exposing dental radiographs, taking impressions, and fabricating provisional crowns. Along with crowns, Rt1 Dental offers veneers which are wafer-thin, custom-made shells of tooth-colored materials designed to cover the front surface of teeth to improve your smile. Many people are skeptical about other procedures like cavities and root canals. During these procedures, pain is thought to be the leading dynamic because of the injections. The assistants and Dr. Trakhtman know of various techniques to help lessen the pain

Chronic periodontitis Chronic Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, leading to progressive destruction of the attachment apparatus of the teeth including periodontal ligament, cementum and alveolar bone with periodontal pocket formation, and recession of the gingival tissue(1) . The clinical feature that characterizes periodontitis from gingivitis is the presence of clinically apparent attachment loss. This loss mainly is associated with changes in the density and height of subjacent alveolar bone (1). Severe generalized periodontitis affects 5–15% of any population worldwide and is a major cause of teeth loss after dental caries (2). Chronic Periodontitis also known as adult periodontitis or chronic adult

The crown of a tooth is the top part, the only exposed main part. Enamel which is the hardest substance inside the human body, covers the whole crown. Usually there is a yellow-white color area that happens to be very sensitive, that would be the neck of a tooth, it protects the nerves (Collins). The main part in a mouth that gets the most infections is the small 2mm space that is in between the tooth and the gums, that is known as the gingival sulcus (Collins). When woking inside of a patents mouth the anantomy of the human moth will come in handy,

Because all 3 preps had enough normal dentin thickness over the pulp tissue, the need for a liner or a base was not necessary in any of the restorations. The final and maybe most important part of the entire process includes checking the occlusion of each restoration using articulating paper. A high restoration could lead to fracture/failure or the restoration and/or pain on mastication. Once confirmed to be normal, the patient is given proper home instructions which include not eating anything for the next 2 hours.

-All teeth have been recorded according to FDI nomenclature. Radiographic Examination: A combination of panoramic and peri-apical radiographs was taken by a dental experienced radiologist, using Cranex 3+ Ceph (Sore dex orion corporation, Finland) X ray unit and Kodak (MXG and Dental Intra oral E- speed) films (Estman Kodak Company, Rochester New York USA). The prei-apical radiograph has been taken when the tooth apical area was not clear on the panoramic view. The paralleling technique was used for taking the peri-apical radiographs (using Endo Ray II film holder, Dentsply Rinn Corporation USA).

Periodontal disease destructs the tissues the form around the teeth, including the gums, periodontal ligaments, and tooth sockets. A patient may notice bleeding, tender, and/or swollen gums, mouth sores, shiny appearance to the gums, or in some cases, hypertrophic gingivitis. If gingivitis isn’t taken care of in its early stages, it can result in an infection of the gums or jaw bones or in some cases, trench mouth. Trench mouth is a form of gingivitis that results when there are copious amounts of normal bacteria in the mouth. The gums become infected and form painful ulcers and gingivalgia.

It can vary in thickness and hardness on each tooth, from tooth to tooth and from person to person. It can also vary in color (typically from yellowish to grayish white) depending on variations in the thickness, quality of its mineral structure and surface stains. Enamel has no blood or nerve supply within it. It is enamel’s hardness that enables teeth to withstand blunt, heavy masticatory forces. Enamel is so hard because it is composed primarily of inorganic materials: Roughly 95% to 98% of it is calcium and phosphate ions that make up stronghydroxyapatite crystals.

If treatment for ECC is delayed, the difficulty in treatment and the cost effectiveness increases. The most common immediate consequence of untreated dental caries is dental pain affecting their eating, talking, playing and sleeping. Children having ECC are at greater risk of developing more caries in their primary and permanent dentition. Severe ECC can deteriorate the child’s anterior esthetics at an early age. Subsequently, the child may suffer from difficulties involving speech articulation as these initial years are critical for speech development.

“The benefit of CAD/CAM technology is that it allows the practitioner the ability to produce esthetic, well-fitting prosthetic dental restorations onsite in a matter of hours” (Kotrzewski). The ultimate convenience of this technology is that the restoration can be placed in the same day on the damaged tooth, whereas older techniques require temporaries for several weeks while the prosthetic is being sent to an offsite laboratory and produced. This technology has caused the dental restorations that are designed and produced in an easier and more simple manner. It has also improved the speed of the creation of the restorations, therefore CAD/CAM has become a highly used and competent dental technology in dental

Traditional restorative dentistry propagated early operative intervention to remove diseased tissue and bacteria. Modern dentistry, however, emphasises on arresting the caries progression and restoring the tooth with minimum tissue destruction. Minimal invasive dentistry is based on this axiom. A drawback in restorative dentistry is the occurrence of secondary caries[18,19] that has compelled us to practice a more extensive form in the past.
