An infant aged one and a half year is experiencing the eruption of a fresh tooth. This particular tooth is most likely a decidous___________?
Show answer Hide answer
Answer: D. Maxillary canine
Explanation
Deciduous canines erupt later than incisors, usually appearing around eighteen months of age. Maxillary canines occupy a posterior position relative to the primary incisor teeth. Chronological dental eruption charts place maxillary canine emergence after primary first molars. Primary dentition consists of twenty teeth developing sequentially throughout early childhood. Deciduous canines feature prominent facial bulges and long single roots. Dental age estimation relies on comparing observed eruption patterns with standard norms.
Pediatric dental examinations monitor eruption sequences to detect developmental delays early. Primary canines play an important role in establishing canine guidance during lateral jaw excursions. Parents often notice localized gingival inflammation during active primary tooth eruption phases. Maxillary central incisors erupt much earlier, typically around eight to ten months. Mandibular lateral incisors emerge relatively early in the normal infant eruption sequence. Maxillary lateral incisors erupt before the child reaches one and a half years.
