Exploratory and confirmatory factorial analysis of the OHIP-Edent instrument

Abstract Several instruments have been used to measure oral health-related quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in the literature that structurally analyze the instruments to verify whether they measure the requirements to which they were designed to. The objective of the study was to evaluate the internal structure of the OHIP-Edent questionnaire. The OHIP-Edent was administered to 54 edentulous patients' wearers of conventional complete dentures. For structural analysis, an exploratory factorial analysis (EFA) was carried out. After determining the internal consistency of the model (Cronbach's alpha = 0.88), the fit was checked using the root mean square error approach (value 0.04), the comparative fit index (value 0.982) and the Tucker-Lewis index (value 0.976). After analysis of the 19 questions and the seven domains proposed in the OHIP-Edent questionnaire, the hypothetical factorial model showed three dimensions denominated "Physical Impact", "Psychological Impact" and "Social Impact". In this sample of conventional complete denture wearers, the OHIP-Edent seems adequate to measure the "Physical Impact", "Psychological Impact", and "Social Impact" of the OHRQoL. The confirmatory factorial analysis confirmed the model and, through adjustment indexes, it was verified that the three dimensions have convergence and consistence adequate in order to characterize the OHRQoL construct with validity.

Deep pain sensitivity is correlated with oral-health-related quality of life but not with prosthetic factors in complete denture wearers

ABSTRACT Low pressure Pain Threshold (PPT) is considered a risk factor for Temporomandibular Disorders (TMD) and is influenced by psychological variables. Objectives To correlate deep pain sensitivity of masticatory muscles with prosthetic factors and Oral-Health-Related Quality of Life (OHRQoL) in completely edentulous subjects. Material and Methods A total of 29 complete denture wearers were recruited. The variables were: a) Pressure Pain Threshold (PPT) of the masseter and temporalis; b) retention, stability, and tooth wear of dentures; c) Vertical Dimension of Occlusion (VDO); d) Oral Health Impact Profile (OHIP) adapted to orofacial pain. The Kolmogorov-Smirnov test, the Pearson Product-Moment correlation coefficient, the Spearman Rank correlation coefficient, the Point-Biserial correlation coefficient, and the Bonferroni correction (α=1%) were applied to the data. Results The mean age (standard deviation) of the participants was of 70.1 years (9.5) and 82% of them were females. There were no significant correlations with prosthetic factors, but significant negative correlations were found between the OHIP and the PPT of the anterior temporalis (r=-0.50, 95% CI-0.73 to 0.17, p=0.005). Discussion The deep pain sensitivity of masticatory muscles in complete dentures wearers is associated with OHRQoL, but not with prosthetic factors.

Evaluation of complete denture patients using graphoanalysis: A clinical study.

Purpose of the Study: The purpose was to analyze and classify behavioral pattern of complete denture patients and to identify difficult patients. Materials and Methods: Fifty complete denture patients were randomly selected for the study. Their behavioral pattern was categorized using House classification as philosophic, indifferent, exacting and hysterical. The above behavioral classification was based on two methods namely interview and questionnaire and graphoanalysis. Accuracy of the above-mentioned two methods in predicting behavior of complete denture patients was statistically evaluated. Results: On analyzing the data it was found that a significant correlation exists between handwriting pattern and behavior of an individual. Further it was noticed that chances of identifying difficult patients such as hysterical was more effective by employing graphoanalysis than questionnaire and interview method. Conclusion: Graphoanalysis in addition with properly structured interview and questionnaire is useful in evaluation of behavior of an individual especially for recognizing difficult patients.

Comparison of patients satisfaction with replacement complete dentures fabricated by copy denture technique versus conventional technique

To compare the level of patients satisfaction with replacement complete dentures fabricated by copy denture technique versus conventional technique. This was a Quasi experimental comparative study [Phase 2 trial]. Conducted from May 2005 to May 2006 at the Department of Prosthodontics, AFID, Rawalpindi. First 60 patients seeking replacement complete dentures were registered and divided into two groups. Group -A patients were given dentures fabricated by copy denture technique and Group-B patients were given dentures fabricated by conventional denture fabrication technique. The patients satisfaction level was assessed after 6 weeks of denture insertion with the help of a questionnaire. Questions about appearance, looseness of dentures, ability to chew food, ability to taste foods, speech and comfort of the patients were asked from each of the patients. Each of the questions had three answers [a] Good [b] Fair and [c] Poor. Good was given a scoring rate of 3, fair a scoring rate of 2 and poor a scoring rate of 1. The maximum scoring rate was 18 and minimum was 6. The patients who had a rate of 15 to 18 were categorized as highly satisfied, from 11-14 were categorized as fairly satisfied and from 06 to 10 were categorized as poorly satisfied. In group A, 10 patients [33%] were highly satisfied, 11 patients [36%] were fairly satisfied and 7 patients [23%] were poorly satisfied. Chi-square test was applied for the comparison of satisfaction level of the two groups. Differences in satisfaction scores between the subjects belonging to the two groups were statistically significant. The p value was 0.002. Copy denture technique is a valid, biologically acceptable and cost effective treatment modality
