Smooth surface caries progression

  • The occlusal, approximal, and smooth surfaces at the gingival margins of teeth are very susceptible to dental caries, which usually develop in areas of stagnation where plaque can accumulate undisturbed (1). Current evidence from epidemiological studies focusing on children, young adults, and adults have shown a shift in
Visual examination, probing, and X‐ray imaging confirmed smooth surface caries on the mesial surface of the maxillary left third molar (Figure 1A). Caries of the affected site progressed up to the dentine, and probing showed that the areas were slightly soft. Cold water and heat did not induce pain.

Smooth 2D surface. Ask Question. I am wondering about the possibility to smooth the plot or make it somehow better, since now the pixels are too big. library(ggplot2) library(reshape2) #.

  • The QLF method has been tested in several in-vitro, 40-42 in-situ, 43 and in-vivo 44-49 studies for smooth-surface caries lesions. Adapting the QLF method for occlusal caries diagnosis is under investigation. 50 The sensitivity of the system is reported to be 80% to 96%, with a specificity of 11% to 80%. 51,52
  • 2- Smooth surface caries I- Interproximal caries: •Usually begins just below the contact point and appears in initial stages as a faint white opacity of enamel without loss of continuity of enamel surface. •The early chalky white spot becomes roughened owing to superficial decalcification of enamel.

    Enamel caries tends to occur on smooth surfaces or pits/fissures Pre-cavitated enamel lesions are composed of 4 zones – translucent zone, dark zone, body of lesion and surface zone Post-cavitated lesions have several zones in dentine – sclerotic zone and the body (divided in to zones of demineralisation, penetration and destruction)

    Apr 19, 2018 · As a consequence, the decay may cause an eruption in the surface and further on develop the cavity. Smooth surface cavity – Contrary to the pit and fissure cavity, this one is created in the empty spaces where the teeth touch, or it can be seen along the line where the gums and teeth meet. That can be a less severe cavity than the first one because it’s more visible and it can be easily cleaned through careful flossing.

    This technique is used to treat smooth surface white spot lesions microinvasively. It is based on the infiltration of an initial enamel caries lesion with low-viscosity light-curing resins called infiltrants. The surface layer is eroded and desiccated, followed by resin infiltrant application.

    Steps in the formation of dental caries (pg 262-263) o Incipient lesion, untreated incipient lesion, progression Incipient lesion Subsurface demineralization: o Acid products from cariogenic dental biofilm pass through microchannels (pores) from the surface of the enamel to the subsurface area in the dentin. Visualization: o The area of demineralization is not visible by clinical observation ...

    These acids will not cause tooth decay, but they can slowly dissolve the enamel surface directly over time (a process called erosion). Some sugar-free gums are designed to help fight tooth decay and are particularly useful if you have a dry mouth (many medications can cause a dry mouth).

    In section, the smooth-surface lesion is conical as a result of systematic variations in dissolution along the enamel prisms. The conically shaped lesion represents a range of increasing stages of lesion progression, beginning with dissolution at the ultrastructural level at the edge of the lesion (Bj0rndal & Thylstrup, 1995).

    Erosive tissue-loss in dental enamel is of significant clinical concern because the net loss of enamel is irreversible, however, initial erosion is reversible. Micro-hardness testing is a standard method for measuring initial erosion, but its invasive nature has led to the investigation of alternative measurement techniques. Optical coherence tomography (OCT) is an attractive alternative ...

    lesions), missing (due to caries), or filled tooth surfaces in any primary tooth in a child 71 months of age or younger [5]. In children younger than three years of age, any sign of smooth - surface caries is indicative of severe early childhood caries (S - ECC). During this period the children are still too young to be

    This study demonstrated that incipient, smooth surface caries can be produced experimentally in the course of 23 days, when active oral hygiene procedures are abolished and frequent sucrose rinses are performed. After sixty days of meticulous oral hygiene and daily mouthrinses with 0.2% NaF there was regression of enamel lesions.

    rampant caries: usually rampant caries occurs after what: excessive and frequent intake of sucrose or after xerostomia: what lesions form more quickly because the cementum is softer in this area: root surface: what kind of caries start to form in tiny spaces between the tooth and the margins of a restoration: secondary ( recurrent ) caries

    Jul 01, 2020 · The caries infiltration technique appears to be the only microinvasive treatment approach currently available for stopping caries progression while restoring incipient proximal carious lesions and smooth-surface white spot lesions.

LF method was validated for occlusal dentinal caries detection by comparing LF readings with the actual lesion depth, determined by opening the fissures. LF readings obtained on smooth surface white spot lesions were compar ed with corresponding measurements by QLF, which served as a reference method. Oper ator agreement was also tested.
9.5.1. in early stages it has histological zones similar to smooth surface caries 9.5.2. shape of lesion differs bacause of different angulation of enamel rods 9.5.3. lesion start as 2 cones with their bases on lateral surface of fissure and later they coalesce to form one cone at depth of fissure
The aim of this study was to assess the possibility of digital image analysis of pit-and-fissure discoloration in order to diagnose caries. Digital images showing pit-and-fissure discoloration in 100 teeth of 19 patients were analyzed to obtain the fractal dimension (FD) and the proportion of the area of pit-and-fissure discoloration to the area of occlusal surface (PA).
