Furcation involvement in molars strongly associated with molar loss

This registry-based retrospective cohort study aimed to evaluate the impact of furcation status on the risk for molar loss.

Subjects with and without furcation involvement (FI) in 2010/2011 were identified in a nationwide registry in Sweden (age- and gender-matched sample: 381,450 subjects; 2,374,883 molars). Data on dental and periodontal status were extracted for the subsequent 10-year period. Impact of Furcation involvement (at baseline or detected during follow-up) on molar loss (i.e., tooth extraction) was evaluated through multilevel logistic regression and survival analyses.

Results

• Furcation involvement had a significant impact on molar loss.

• Furcation involvement degrees 2 and 3 resulted in adjusted risk ratios of 1.67, respectively. Following the first detection of deep Furcation involvement (degrees 2–3), estimated survival decreased by 4% at 5 years and 8% at 10 years.

• In addition to Furcation involvement, endodontic status and probing depth were relevant risk factors for molar loss.

Furcation status had a clinically relevant impact on the risk for molar loss. However, after first detection of deep Furcation involvement, the decline in molar survival was minor.
