Detailed explanation-1: -Each of the primary molars is replaced by permanent, premolar teeth. There are three permanent molars in each quadrant that are not succeeded by primary teeth and may be referred to as non-succedaneous teeth.
Detailed explanation-2: -The permanent incisors, canines, and premolars are called succedaneous teeth because they replace (succeed) the primary teeth.
Detailed explanation-3: -Three permanent molars do not succeed primary teeth in each quadrant; therefore they are nonsuccedaneous teeth.
Detailed explanation-4: -The mandibular molars precede the maxillary molars. The first permanent molar (maxillary or mandibular) erupts posterior to the second deciduous molar, taking up a position in contact with it. Therefore the first molar is not a succedaneous tooth because it has no predecessor.
