BackgroundThe OHIP-49 is widely used to assess oral health-related quality of life, but its length makes it time-consuming and difficult to use. An abbreviated version of the OHIP-49 with fourteen items has been validated for older adults, but not in Chile. The aim was to develop and validate the Spanish version of the OHIP-14 in an elderly Chilean population.MethodsTwo studies were conducted; a cross sectional to develop and a retrospective study to validate the OHIP-14Sp. The OHIP-49Sp was applied to 490 older adults and the fourteen questions with the higher impact on oral health-related quality of life were selected through linear regression. These items were applied on a retrospective dataset of 85 older adults to test internal consistency (Cronbach’s alpha). A discriminative validity analysis was performed along with the assessment of sociodemographic (age and gender, educational level) and clinical variables (number of teeth, caries lesions, CPITN, prosthetic needs and prosthetic functionality). Data were analyzed using Mann–Whitney U, Student’s t and one-way ANOVA tests with a 95% confidence level and finally were analyzed by a Multivariate Logistic Regression Model.ResultsHigh internal consistency values were obtained for the OHIP-14Sp instrument (0.91). There was an association between the OHIP-14Sp scores and the presence of caries (p = 0.003), need for complex periodontal treatment (p = 0.002), prosthetic needs (p < 0.0001) and age younger than 70 years-old (p < 0.0001). Subjects with periodontal treatment need were more likely to report reduced oral health-related quality of life (PR = 2.10).ConclusionsThe OHIP-14Sp proved to be a consistent and valid tool to assess oral health-related quality of life when tested in Chilean older adults.

The OHIP-49 Sp proved to be a valid tool to assess oral health-related quality of life, when tested in Chilean older adults.

The hypothetical factor structure was confirmed by the CFA for 16 and 8 items versions. The information contained in abbreviated items allows measuring oral health related quality of life in Chilean children.

Objetive: To evaluate microleakage of composite resins (CR) placed over different cavitary liners after managing deep caries lesions through selective removal of soft carious tissue to soft dentin (SRCT-S). Material and Methods: Fifty four human teeth were collected for microleakage testing. Each assay comprised ICDAS 5 or ICDAS 6 carious lesions and sound teeth for controls. Sound teeth were prepared with cavities that mirrored the carious teeth cavities, which were prepared with SRCT-S. Sound and carious teeth were further randomly assigned to one of the three experimental groups: Group A: universal adhesive (UA) + CR, Group B: glass ionomer cement liner + UA + CR, and Group C: calcium hydroxide + UA+ CR. Occlusal microleakage (OM) and cervical microleakage (CM) was classified within one of 5 depth categories. ANOVA and Chi-square tests were computed (p<0.05). Results: OM and CM were similarly distributed across subgroups (p>0.05). All Group C samples with carious lesions presented some degree of microleakage. However, no statistically significant differences were observed between groups and within each group (p>0.05). Conclusion: Teeth restored with CR after SRCT-S using calcium hydroxide as a liner material seem to exhibit higher microleakage than those restored using glass ionomer or UA alone. Further clinical research is needed to deepen these findings. Clinical significance: The application of calcium hydroxide as a liner under a composite resin may reduce the longevity of a restoration after performing selective or partial removal of carious tissues. Clinicians should rethink the need of using calcium hydroxide for this application, albeit the lack of clinical evidence.
