Tooth Loss And Health Related Quality of Life: ENS 2016-2017

Objectives: To evaluate the impact of tooth loss on health-related quality of life (HRQoL) in Chileans aged over 15 years, who participated in the 2016-2017 National Health Survey (ENS 2016-2017).
Methods: This study included 5473 individuals who underwent an intraoral examination. The EQ-5D questionnaire was used to measure HRQoL, which evaluates five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The answers could be G1 = no problems, G2 = some problems, or G3 = problems. The dependent variables were the number of remaining teeth and anterior tooth loss. Means and proportions were calculated with their respective standard errors and 95% confidence interval (CI) using complex sampling models. Linear regressions were performed for the number of teeth and logistic regressions for anterior tooth loss. In logistic regressions, Odds Ratios (OR) were obtained with their 95% CI. We adjusted by age, sex, geographical area, and educational level.
Results: In "self-care" dimension, the number of teeth followed a significant distribution (p-value = 0.01) with 20.59 teeth (sd 0.44) in G1, 18.53 (sd 0.85) in G2 and 17.43 (sd 1.73) in G3. Concerning mandibular anterior tooth loss, a G2 individual had an OR of 1.58 (95% CI 1.05-2.39), while a G3 had an OR of 2.04 (95% CI 0.67-6.13). For “usual activities”, the number of teeth decreased significantly (p-value = 0.01) from a mean of 20.17 (sd = 0.34) in G1 to 16.85 (sd = 1.17) in G3. The mandibular anterior tooth loss increased from 1.42 (95% CI 0.96-2.10) in G2 to 3.24 (95% CI 1.34-7.81) in G3. The other EQ-5D dimensions did not show consistent gradients for anterior tooth loss.
Conclusions: A lower number of remaining teeth was associated with lower HRQoL scores in all EQ-5D dimensions. Concerning anterior tooth loss, it was associated with lower HRQoL, especially in “self-care” and “usual activities.”
