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.
As a dentist there can be many scary events that could occur, one being diseases. If dentists find that a disease could be in a client’s mouth, it must be taken care of right a way. The worst disease is oral cancer. This has caused many people pain and suffering along with death. It is a serious subject that dentists have to deal with.
Dental caries is one of the most common and2 multifactorial human diseases that has widely affected vast majority of individuals all over the world3.It is induced by acids developed by the dental plaque adhering to the tooth surface.4 Different circumstance effect dental aspect.Interaction between detrimental and defensive factors are crucial.Microorganisms, sugar, and unhealthy eating habits are disastrous to dental aspect, while saliva, oral hygiene, and the natural resistance of the teeth serve as the defensive equilibrium.1 Bacterial plaque plays the initial role in the pathogenesis of the disease. Dental plaque is a ordinary term for the diverse microbial community (predominantly bacteria) found on the tooth surface, fixed in a matrix
The activity of lesions need to be determined as cavitated lesions continue to trap bacterial plaque and need to be restored. A single observation will only tell the clinician about the condition of the tooth at that single point in time; but, it will not determine whether the demineralization increasing or, perhaps decreasing. The small lesion needs to be well examine than the larger lesion (Whitaker., 2006). Most of dental caries detection research focused occlusal and smooth surface caries. A critical factor to consider is that
Teeth also can regain minerals in a natural process called remineralisation. Saliva helps minerals biuld back up in the teeth (flouride foods does the same).2 Dental decay begins inside the tooth's enamel when minerals are being lost faster than they are being regained. The longer the food stays near the bacteria on the tooth, the more acids will be produced.
ADVERTISEMENT Dental stones gradually spread from the crown, dental calculus for each progress, alveolar bone atrophy some, over time, the teeth gradually loose, dental stones will be punctured needle, and gradually spread to the root parts. For the mouth, the stone is a foreign body, its existence itself will continue to stimulate the periodontal tissue and oppression of the gums, affecting the oral local blood circulation, resulting in periodontal tissue infection, causing inflammation of the gums atrophy, the formation of periodontal bags. When the periodontal bag formation, food residues, plaque and stones and other more easily deposited, further damage to the deeper periodontal ligament, so the result of a vicious cycle, and finally
Removal of irritants from root canal b. Drainage c. Sinus tract resolves after RCT VII. EXTERNAL ROOT RESORPTION 3 types are common: apical, lateral and cervical root resorption. Etiology: a. Infected necrotic pulp tissue b. Over-instrumentation during RCT c. Adjacent impacted tooth d. Trauma e. Granuloma/cyst Signs and Symptoms: a. Asymptomatic b. Mobile root after complete resorption c. Pink tooth is observed if the resorption reaches the crown Diagnosis: a.
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
It is important to know that periodontal disease come as a result of plaque, also known as biofilms being on the tooth as well as gums for a long time. On this list is tartar, which is basically hardened plaque. This disease can be as simple as a gum inflammation or take an extreme form. Previously, it was believed that any bacteria led to development of biofilms. However, it is now being discovered that it is tussle between bad bacteria and any bacteria.
Flood waters commonly contain high levels of bacteria. Small depressions filled with flood water provide an excellent breeding ground for bacteria. Whenever a well is inundated by flood waters or surface runoff, bacterial contamination is likely. Shallow wells and wells that do not have water-tight casings can be contaminated by bacteria infiltrating with the water through the soil near the well, especially in coarse-textured soils. Older water systems, especially, dug wells, spring-fed systems, and cistern-type systems are most vulnerable to bacterial contamination.
