Dental Anatomy
Maxillary lateral incisor agenesis:
This is the most common congenital absence of a permanent tooth in the maxillary
anterior region, accounting for about 20% of all dental anomalies.
Coronal developmental invagination (DI):This is a common anomaly in the
permanent maxillary lateral incisor, usually appearing as an accentuation of the
lingual pit.It's often bilateral.
Peg-shaped crown:This is a common alteration in the maxillary lateral incisor.

Public Health DentistryDental plaque is a bacterial biofilm that forms on the teeth and is a common factor in the development of both dental caries and periodontal disease. While fluoride in drinking water can help prevent dental caries, it is not directly related to periodontal disease. Nutritional disturbances can affect the overall health of the individual but are not the sole cause of either condition. Disturbed occlusion may be a risk factor for certain dental issues but is not universally common to both diseases.

Dental Materials
Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin. This is the main method of adhesion of composite resin to tooth surface.
After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.

Microfilled composites have a very high surface area with silica particles diameters of 0.04 to 0.2 µm, which provides excellent aesthetic results and polishability.
