this essay I will be discussing the Saber-tooth Curriculum and how it is linked to the implementation of Outcomes Based Education and the National Curriculum Statement. The Saber-tooth Curriculum is a famous satire on curriculum development‚ which was published in 1939. It tells the story of New-Fist‚ and his curriculum. In a post-apartheid South Africa we can still learn a great deal from this satire. The universal principle is illustrated by the Saber-tooth Curriculum and I will also be reflecting

the dental lamina and the tooth germs‚ causing anomalies in the number‚ size and form of teeth (abnormalities of morphodifferentiation) or to abnormalities in the formation of the dental hard tissues resulting in disturbances in tooth structure (abnormalities of histodifferentiation). Abnormalities of histodifferentiation occur at a later stage in development than abnormalities of morphodifferentiation; in some disorders both stages are abnormal. Histophysiology of tooth development: A number

Caries Lesions Tooth surface loss is a process that results in non-carious lesions. Several categories of tooth surface loss exist‚ including attrition‚ abrasion‚ erosion and abfraction. (Dentistry‚ n.d.) Non caries lesions will be discussed: • Attrition (wear) • Abrasion • Erosion • Enamel hypoplasia • -Enamel hypocalcification • -Discoloration • Malformation Causes of non caries lesions: - Bruxism - Clenching - Disease - dietary factors - habits and lifestyle - incorrect tooth brushing - abrasive

Odontogenisis The origin or the development of the tooth and tissue formation is known as Odontogenisis. The formation of the tooth begins at six weeks in the human embryo. However not all tooth develop at the same time. Although Odontogenisis is a continuous process it is divided into various stages. These stages are Bud stage‚ Cap stage and Bell stage which is followed by root formation and eruption. The basal layer of the ectoderm which is derived from the oral epithelium at the stomadeum

issues are some of the most apparent. From tooth decay to gum disease and the complete loss of teeth‚ many different oral health problems are common in people who regularly use illicit drugs and frequently consume alcohol. Tooth decay is a common problem that arises from frequent alcohol consumption—in both alcoholics and those whom indulge in binge drinking. This is because many alcoholic drinks are high in sugar which demineralizes and weakens tooth enamel. The risk may be slightly higher in cases

different types of force characteristics such as heavy versus light forces and continuous versus intermittent force and the type of tooth movement influence the rate and force of orthodontic tooth movement. Heavy forces generally results in pain development‚ necrosis of cellular components within the PDL and undermining resorption of alveolar bone adjacent to the affected tooth (Proffit‚ Fields‚ & Saver‚ 2013). A study carried out by Alikhani et al.‚ observed a linear relationship between the magnitude
