Dental caries is a result of shift in the balance of mineral loss and gain, leading to more changes in the tooth structure, which cannot be accepted as healthy but should be considered as pathological. This change of dental caries from a physiological process to pathology is continuous and affected by numerous variables and also there is a lack. There is great interest in identifying the subset of individuals in the population that are more susceptible to dental caries. We proposed that a portion of these particular individuals are more susceptible to dental caries due to changes in dental enamel that are related to amelogenin genomic variation. However, apparently amelogenin function can be impacted by inflammation, and this can lead. Enamel carious lesions are characterized by mineral loss in the body of the lesion, whereas the surface remains comparably highly mineralized. 2,12 The pores within the body of enamel caries provide diffusion pathways for acids and dissolved minerals. Therefore, an alternative approach for superficial sealing might be to arrest carious lesions by infiltration of these pores with light-curing. enamel caries and resin infiltrant composition might affect hydrolytic degradation of resin infiltrant, the aim of this study was to evaluate the effects of resin infiltrant composition and caries histological zone on the variation in microhardness of resin-infiltrated artificial bovine enamel caries (RI-AEC) upon water immersion hydrolytic Part II The caries lesion and its biological determinants.

Significant differences are shown between the mechanisms operating on the various dental hard tissues during development of caries. Histologically distinguishable reaction. Using histology as the gold standard, it was found that 12 teeth were sound (non-CD), while 50 teeth had enamel and dentine caries (CD). The validity tests at the enamel histological caries level, ΔRmax (ρ = 0.80) were strongly correlated with the histology (P < 0.001)

Dental Caries Causes. Dental caries (tooth decay) is a multifactorial process that is caused by several factors. These factors are: Bacteria: they decompose carbohydrates and produce acidic metabolites that attack tooth enamel. Carbohydrate: it provides the basis of life for bacteria. Poor oral hygiene: lack of dental care promotes bacterial growth, proliferation and the formation of plaque To investigate the validity of micro-CT for in vitro caries detection in comparison with histology as the reference standard. Methods: A systematic search was conducted in the databases Latin American and Caribbean Health Sciences (LILACS), LIVIVO, PubMed, Scopus and Web of Science from their inception to 16 January 2019

Enamel hypoplasia is a defect of the enamel that only occurs while teeth are still developing. Still, it can affect both baby teeth and permanent teeth. The condition results in thin enamel, which. The objectives of the present study are to elucidate the indications for VPT and to present a set of histopathology and histobacteriology-based guidelines for VPT in teeth with deep caries. METHODS: Two hundred and sixty-four carious, unrestored and VPT-treated human teeth, which were extracted for reasons not related to the present study Types of Pulp. Figure 5 illustrates the regions where the two types of dental pulp are located:. 1. Coronal pulp (A) (Lab Image 3) occupies the crown of the tooth and has six surfaces; occlusal, mesial, distal, buccal, lingual and the floor.. Pulp horns (B) are protrusions of the pulp that extend up into the cusps of the tooth.With age, pulp horns diminish and the coronal pulp decreases in.

High intensity infrared light from the pulsed Nd:YAG dental laser is absorbed by pigmented carious enamel and not absorbed by normal enamel. Therefore, this system is capable of selective removal of surface enamel caries. Safety and efficacy of the clinical procedure was evaluated in two sets of clinical trials at three dental schools. Carious lesions were randomized to drill or laser treatment Dental fluorosis is a common disorder, characterized by hypomineralization of tooth enamel caused by ingestion of excessive fluoride during enamel formation.. It appears as a range of visual changes in enamel causing degrees of intrinsic tooth discoloration, and, in some cases, physical damage to the teeth.The severity of the condition is dependent on the dose, duration, and age of the. Depth of caries was measured, and finally Intraclass Correlation Coefficient (ICC) and Bland-Altman plot were used to show the agreement between the methods.The software diagnosed 60% of enamel caries. The ICC (for detection of enamel caries) between the computer software and histological analysis results was determined as 0.609 (95% confidence. Four teeth were lost during histological preparation, leaving 96 teeth for further evaluation. Of the 96 sites selected, 27 were histologically sound, 16 had shallow and 16 deep enamel caries, 26 had superficial and 11 deep dentine caries. Correlation coefficients between histology and ICDAS scores varied between 0.55 and 0.71 Enamel structure is of importance in demineralization. Differences in porosity in enamel effect the rate of demineralization, seen between permanent and deciduous teeth. Individual differences have been shown in the mean mineral concentration values in enamel, the role of this in demineralization is not thoroughly investigated. The aim of this study was to study variations of depths of.

However, while OCT demonstrates a structural difference in the enamel in the region of the caries, this technique provides little insight into the source of this difference. Raman spectroscopy provides biochemical measures derived from hydroxyapatite within the enamel as well as information on the crystallinity of the enamel matrix In the present study, out of 50 teeth 48 (96%) were diagnosed as cariously involved by visual examination while histology detected caries in 44 teeth (88%) .The similar findings were observed by Rocha et al. and Bengston et al. where visual method detected caries in 100% of the sample whereas histology showed caries in 90% of the sample. When comparisons were made between visual examination.

Hidden caries (defined as caries in the dentin without an opening through the enamel leading to it) was a phenomenon that was noticed in 1868 (Knapp, 1868). Early childhood caries, or labial decay of childhood, was described in 1884 (Darby, 1884). Secondary decay was discussed as a problem in 1880 (Palmer, 1880) Regional odontodysplasia (ROD) is uncommon developmental anomaly, which tends to be localised and involves the ectodermal and mesodermal tooth components.
