Question

Law of symmetry is not followed by:

• A. Maxillary molars
• B. Mandibular molars
• C. Maxillary premolars
• D. Mandibular premolars

Hint:

Maxillary molars often show greater variability in their morphology and position compared to other teeth, making them an exception to the law of symmetry.

Answer 1

The Correct Option is A

The law of symmetry in dentistry states that teeth in the left and right sides of the dental arch should be symmetrically positioned with respect to the midline of the face. However, this law is not always followed due to variations in tooth size, shape, and position. In general, maxillary and mandibular teeth are symmetrical in shape and position within their respective arches. 
However, maxillary molars are an exception to this rule because they often exhibit more variation in their size, shape, and position compared to other teeth. Maxillary molars have three roots, which can vary in size, shape, and position, leading to variations in the overall shape and position of the tooth. 
Additionally, the maxillary sinus, which is located above the maxillary molars, can also affect the position and shape of these teeth. Therefore, the correct answer to the question is option 1: maxillary molars do not always follow the law of symmetry in dentistry due to variations in their size, shape, and position.
