After 24 months:

• Investigation of the success rate of Class II composite resin restorations in primary molars that have undergone pulpotomy.
• Comparison of Class II composite resin restorations in primary molars that have undergone pulpotomy with restorations of the same type in the same patient, in which no pulpotomy has been performed.

The null hypothesis of the study is that there is no statistically significant difference in the success of Class II resin restorations after their placement in primary molars, regardless of whether a pulpotomy has been performed or not.

Inclusion Criteria:

• Healthy children aged 3-9 years

  • At least one pulpotomy in a carious primary molar requiring a Class II resin restoration
  • At least one Class II cavity in a carious primary molar in the same patient that requires a resin restoration
  • The teeth to be restored must not present clinical signs of pulp necrosis, such as pathological mobility or abscess/fistula
  • Parents have signed an informed consent form
  • The young patients return for evaluation at 12 and 24 months
  • There is no exfoliation or extraction of the evaluated teeth before the 24-month period
