Microabrasion
The aesthetics of a child’s anterior teeth is a concern for both children and their parents alike. Yellow or brownish-yellow defects are of full thickness, and therefore may respond to bleaching with carbamide peroxide. However, careful consideration should be made of the risks including hypersensitivity, mucosal irritation and enamel surface alterations.Creamy-yellow or whitish-creamy defects are less porous and variable in depth, and may respond to microabrasion with 18% hydrochloric acid or 37.5% phosphoric acid and abrasive paste. Again, this should be undertaken cautiously as microabrasion may result in loss of enamel. Veneers
Direct or indirect composite veneers can be effective in improving aesthetics with minimal tooth tissue removal. Ceramic veneers as a treatment option should be delayed due to the risks of resulting in a short clinical crown height, immature tooth pulp irritation and also the instability of the gingival margins during the eruption of teeth.

Fissure sealants
The placement of fissure sealants on permanent molars without post-eruptive breakdown should be undertaken. Use of a 5th generation bonding adhesive prior to fissure sealant application may improve retention rates of fissure sealants.For partially erupted molars with inadequate moisture control, glass ionomer cements (GIC) can be considered as an interim treatment option. As the retention rate of GIC is often poor, replacement with a resin-based fissure sealant is recommended following tooth eruption.Resin-based fissure sealants can be beneficial to patients affected with mild MIH where the first permanent molars have fully erupted, although the degree of hypomineralization affects the bond strength of said sealants.
For example, cancers of the liver parenchyma arising from malignant epithelial cells is called hepatocarcinoma, while a malignancy arising from primitive liver precursor cells is called a hepatoblastoma and a cancer arising from fat cells is called a liposarcoma. For some common cancers, the English organ name is used. For example, the most common type of breast cancer is called ductal carcinoma of the breast. Here, the adjective ductal refers to the appearance of cancer under the microscope, which suggests that it has originated in the milk ducts. Benign tumors (which are not cancers) are named using -oma as a suffix with the organ name as the root. For example, a benign tumor of smooth muscle cells is called a leiomyoma (the common name of this frequently occurring benign tumor in the uterus is fibroid). Confusingly, some types of cancer use the -noma suffix, examples including melanoma and seminoma. Some types of cancer are named for the size and shape of the cells under a microscope, such as giant cell carcinoma, spindle cell carcinoma and small-cell carcinoma. Prevention
Cancer prevention is defined as active measures to decrease cancer risk. The vast majority of cancer cases are due to environmental risk factors. Many of these environmental factors are controllable lifestyle choices. Thus, cancer is generally preventable.
