Which root configuration is typical for an upper molar?

• A. 2 roots
• B. 1 root
• C. 4 roots
• D. 3 roots

Answer: (D)

The usual arrangement for an upper molar is three roots: two on the buccal side (mesiobuccal and distobuccal) and one palatal root. This configuration fits the maxillary bone’s shape and provides strong anchorage to withstand the heavy chewing forces molars endure. In practice, you’ll typically see three roots on an upper molar, and when treating the tooth you’ll plan for three primary root locations (though the buccal root may house more than one canal in some cases). Rare variations can show an extra root (making four), but three roots is by far the most common pattern.
