Dental Anatomy Introduction and Macro Anatomy

Primary Dentition

• The dental formula for the primary dentition (milk, baby, deciduous) in one side is: incisors 2, canines 1, molars 2.

Tooth Morphology

• Lower second premolars have 5 lobes, with 3 buccal and 2 lingual lobes.
• The type of teeth with 5 lobes, with 3 buccal and 2 lingual lobes, are lower second premolars.

Dental Development

• The mixed dentition phase occurs around 6-12 years of age.

Permanent Dentition

• There are 16 permanent teeth in total in both sides according to the dental formula of the permanent dentition.

Primary Teeth

• Primary dentition secondary teeth are also known as succedaneous teeth.

Tooth Notation

• The Palmer Notation System represents a way to identify teeth.
• The letter "R" represents the upper right quadrant in the Palmer Notation System.
• Deciduous teeth are numbered in the Palmer Notation System.

Tooth Structure

• The anatomical crown of a tooth comprises the enamel, dentin, and cementum.
• Triple-rooted teeth are molars.
• The pulp chamber and pulp horns exist in the crown of a tooth.
• The junction between enamel and dentin is also known as the Dentino-enamel junction (DEJ).

Periodontal Tissue

• The periodontal ligament is a connective tissue that acts as a medium for tooth attachment.

Tooth Characteristics

• Enamel, the most mineralized tissue in the body, is translucent and colorless.
• Crowns of all teeth have occlusal, buccal, lingual, mesial, and distal surfaces.
