Abstract:


    • In children and young adults, the permanent first molar (PFM) is highly susceptible to caries due to a variety of reasons: sequence of eruption, location in mouth, diet/hygiene, MIH and tooth anatomy, amongst others. Yet, the treatment options can become limited if this tooth is left undiagnosed and untreated with dental caries. One treatment option that can be presented to families is the idea of ‘Second Molar Substitution’ (SMS). The goal of this treatment modality is to extract the PFM so that the permanent second molar (PSM) can take its place in the dental arch. According to research that was published by the AAPD, the ideal time this should be done is between 8 to 10 years old and when the earliest radiographic sign of bifurcation development in the PSM in the same quadrant is observed. This case report details treatment of 4 PFM extractions using SMS from initial encounter to the subsequent follow-up visits over an 18 month period of a 9-year-old patient with ADHD using only in-office nitrous oxide sedation.
