Final answer:
The maxillary central incisors are the first teeth to appear in each of the maxillary quadrants, followed by the maxillary lateral incisors, and later the maxillary cuspids or canines.
Step-by-step explanation:
The first teeth to be found in each of the maxillary quadrants are the maxillary central incisors. The maxillary central incisors are the sharp front teeth used for biting into food, and they typically emerge first at about six to ten months of age. Following the central incisors are the maxillary lateral incisors, then the maxillary cuspids or canines, which emerge at roughly ten months and between 16-24 months, respectively. The canines are flanked by the incisors and have a pointed edge (cusp) used for tearing food. Posterior to these are the maxillary first premolars, which are not present in the primary dentition and appear during the transition to permanent teeth, typically around the age of 10-12 years.
