Developing a short form of Oral Health Impact Profile (OHIP) for dental aesthetics: OHIP-aesthetic.
ABSTRACT To develop and evaluate shortened forms of the Oral Health Impact Profile (OHIP) for discriminating dental aesthetics problems and evaluating dental aesthetic outcomes.
Eighty-seven subjects self-completed the 49-item OHIP at baseline and 63 at follow up (8 weeks later), with the intervention of applying an array of tooth-whitening products. Expert-based approach and regression analysis (on baseline data) were undertaken to derive two subset questionnaires (OHIP-conceptual and OHIP-regression). Their discriminatory ability for dental aesthetics and their responsiveness to tooth whitening were compared with the original OHIP-49, Slade's OHIP-14 and a Chinese short-form version of OHIP.
The measures developed were strongly associated with self-rating of dental aesthetics (P < 0.001) unlike OHIP-49 (P = 0.03) or other OHIP short forms (P > 0.05). The measures were also reliable (Cronbach's alpha 0.86) and comparable with the other OHIP forms. In terms of effect size, OHIP-conceptual was more effective in measuring changes than the one based on the regression analysis, the original OHIP-49, OHIP-14 and the Chinese version of the short-form OHIP. It also exhibited a less susceptibility to floor effects than other OHIP forms.
A modified short form of the OHIP derived (OHIP-conceptual) was the most favorable in discriminating dental aesthetics, was reliable and most sensitive to the dental aesthetics intervention - tooth whitening.

ABSTRACT: This study described oral health-related quality of life (OHRQoL) before and after treatment in patients with fixed, removable, and complete dentures. OHRQoL was measured using the German version of the Oral Health Impact Profile (OHIP-G) in a convenience sample of 107 prosthodontic patients at baseline and 1 and 6 to 12 months after treatment. The sum of OHIP-G item responses (OHIP-G49, range 0 to 196) characterized OHRQoL impairment in 42 patients treated with fixed prosthodontics, 31 patients treated with removable dentures, and 34 patients treated with complete dentures. OHIP-G49 medians were compared with the OHRQoL level in a general population sample (n = 2,026). A multivariable binomial regression analysis, controlling for the effects of baseline OHRQoL and follow-up wave, was used to compare the level of impaired OHRQoL in different prosthodontic treatment groups at follow-ups. OHRQoL improved in 96% of the subjects. OHIP-G49 medians reached the level of OHRQoL in the general population 1 month after treatment (fixed prosthodontics patients 6 OHIP-G units; general population subjects 5 units; removable denture patients 23 units, 15 units in general population subjects; complete denture patients 13 units, 23 units in general population subjects). OHIP-G49 medians were below population norms 6 to 12 months after treatment. In patients treated with removable/complete dentures, the expected posttreatment OHIP-G49 problem rate was 1.9 times the problem rate in patients treated with fixed prosthodontics, holding baseline OHIP-G49 and follow-up wave constant. OHRQoL changed substantially comparing pretreatment scores with 1 and 6 to 12 months of follow-up in patients treated with fixed, removable, and complete dentures.The International journal of prosthodontics 01/2005; 17(5):503-11. · 1.63 Impact Factor

ABSTRACT: To assess the impact of tooth loss in complete denture wearers using the Oral Health Impact Profile (OHIP), and to compare the validity of 49 and 14 item versions of OHIP in a denture wearing population. In this cross sectional study, data were collected at Newcastle Dental Hospital, UK. Two groups were involved: (1) subjects edentulous in one or both jaws seeking dental implants to retain their intra-oral prostheses (n = 48); (2) an edentulous control group of the same age and gender distribution requesting conventional, complete dentures (n = 35). All participants in the study completed a 49 item OHIP (OHIP-49) and a validated denture satisfaction questionnaire prior to active treatment. OHIP data were computed using the weighted standardised and simple count methods. Non-parametric statistical tests were used to compare the responses of implant and control subjects. Both groups were dissatisfied with their conventional dentures and had relatively similar levels of dissatisfaction. There were statistically significant differences between the groups for all seven OHIP-49 sub-scale scores. Differences between OHIP-14 sub-scale scores were also significant, with presence of teeth influencing the impact on psychological discomfort. Subjects in the implant group were significantly more impaired, disabled and handicapped by tooth loss than subjects seeking conventional dentures. The results suggested that OHIP-49 and OHIP-14 had a similar ability to discriminate between the groups. This indicates that OHIP-14 may be a useful aid in a clinical setting.Community dental health 10/1999; 16(3):176-80. · 0.93 Impact Factor
