It is diseases that should be occurs in to teeth, so author used different digital image processing tools and techniques such as, Dental X-Rays, Image Processing, Image Segmentation and Binarization these all of defined and elaborate Below.
Dental Erosion ABSTRACT: The nature of acids and sugars has both acidogenic and cariogenic properties, which results in enamel loss, tooth sensitivity, loss of vertical dimension and dental caries. The review shows the relationship between dental erosion and caries in children and adults. Introduction: Erosion is condition where there is loss of enamel and dentin triggered by the action of acids with out the involvement of bacteria. The etiology could be intrinsic (gastric acids) or extrinsic (dietary) and the effect is directly related to the consumption for example how many times a day soft drinks were consumed or how many times a day regurgitation of food took place, the greater the number
Changes in bone level and presence of caries can be easily seen by taking a radiograph. During this visit, plaque and calculus should be removed by the hygienist. The effectiveness of the daily oral hygiene methods are evaluated and reviewed. (Concepts,
CONCLUSION In this paper, a novel approach is proposed to detect the measure of the teeth from dental x-ray images. The top hat-bottom hat transformation is followed by smoothening of the image to enhance the contrast and the boundaries of the image respectively. The statistics of the teeth are calculated so as to provide the dentists with an accurate and faster method of the detection of the measure of the teeth. The work has given appreciable results and can be aimed for coloured dental
INTRODUCTION Microleakage has been a key issue in the field of operative dentistry1, but it is not long since it has drawn the attention of orthodontists. From the orthodontic point of view, microleakage is an important factor in the development of two iatrogenic lesions particularly at the adhesive - enamel interface: white spot lesions and decalcification. The presence of fixed orthodontic appliances impedes oral hygiene and facilitates plaque accumulation. This in turn increases the bacterial counts in the plaque around the attachments and the production of organic acids2. In the presence of a low pH in the oral environment, the calcium and phosphate ions diffuse out of enamel resulting in demineralization and white spot lesions3.
Interview techniques borrowed from participatory and ethnographic research can be used during the assessment phase of the dental hygiene process to allow the dental hygienist to systematically explore the factors that may affect the practice of preventive oral health behaviours. (Craig, B et al 1996) Data gathered during this phase can then be used in the planning phase of the dental hygiene process to develop a strategy which is specifically designed to meet the assessed needs of the individual client. (Craig, B et al
Factors as bulimia, gastric acid reflux,acidic medicines and frequent acidic diet exposure represent significant factors in the development of dental erosion(Machado C&Lacefield W,2008). The global increase in the ingestion of acidic beverages such as soft drinks and fruit juices is one of the main causes of high prevalence of dental erosion (Khmverdiz &Mohammed V,2013). Tooth colored direct restorations are often used in erosive lesions for dentin and enamel rehabilitation .physical and chemical properties of dental filling materials are indicators that predict their performance in a clinical setting .The roughening of the surface caused by wear and chemical degradation may affect gloss and consequently increase plaque retention, thus decreasing the longevity of the restoration (Lepri CP&Palma-Dibb RG,2013). Therefore failure or success of aesthetic restorations depends on their behavior under still persisting erosive conditions. The critical oral environment conditions, i.e.
This procedure was adopted by Whittaker and Bakri.11 The translucency of dentin as noted in the ground section is due to an increase in intratubular mineralization. This increase in mineralization has same refractive index as that of peritubular dentin giving translucent appearance within dentin. This translucency is first noted in the apical part of the tooth because of lesser diameter of dentinal tubules in the root dentin compared to the coronal part. Also lesser number of dentinal tubules are noted per unit area in apical part.14,15 The increase in translucency is generally considered as a physiological change with aging process as proved by Azaz et al 21 in his study of impacted canines. They reported increase in dentin translucency with increasing age, even in impacted tooth which is away from any pathological and functional
The classic comparative dental identification makes use of both post-mortem and ante-mortem dental records for determining and excluding discrepancies.  The tentative identification of an individual may be unknown in many cases as ante-mortem samples cannot be located. To aid the search of these cases dental profile of the individual is developed. A forensic odontologist can identify and report indicators for age, time of death, race, and sex with the help of these profiles. Dental identifications are cost effective and accurate and is the main identification method for criminal investigators in mass destruction, grossly decomposed and traumatised bodies where visual identification is neither possible nor
