Detailed explanation-1: -Both maxillary premolars erupt earlier than the mandibular premolars. The maxillary first premolar has a bifurcated root (two roots, one buccal and one lingual). Some first premolars have roots that are joined, or fused. The roots are shorter in length and resemble the roots of the molars.
Detailed explanation-2: -The maxillary first premolars (that are bifurcated) have furcations that are midmesial and mid-distal, and are both located 7 mm from the CEJ. (Figure 3.) The furcations on the mandibular first molars are centered mid-facial and midlingual.
Detailed explanation-3: -Supernumerary roots are one of the development anomalies pertaining to the tooth root morphology. It is generally well known that the deciduous and permanent anterior teeth have a single root. Maxillary molars have three roots and mandibular molars have two roots.
