Orofacial esthetics, chewing function, and oral health-related quality of life in Kennedy class I patients with mini-implant-retained removable partial dentures: A 3-year clinical prospective study.

This prospective clinical study aimed to assess self-reported orofacial esthetics, chewing function, and oral health-related quality of life (OHRQoL) over three years in the Kennedy Class I patients without posterior dentition who received free-end saddle removable partial dentures (RPDs) retained by two mini dental implants (MDIs) inserted in the canine/first premolar region. The study's robust findings reaffirm the viability of MDI-retained RPDs as a treatment modality in contemporary prosthodontics, instilling confidence in the dental community. MATERIALS AND METHODS: 92 participants with posterior edentulism in the maxilla or mandible received 184 MDIs and 92 RPDs. After one year, three participants were excluded, and another seven were excluded after three years. The final sample was 82 participants. Self-perceived orofacial esthetics was assessed by the Orofacial Esthetic Scale (OES), chewing function by the Chewing Function Questionnaire (CFQ), and the OHRQoL by the OHIP-14. Statistical analysis utilized multivariate regression analysis, standardized effect size calculation, Wilcoxon Signed Rank test, and Friedman's test. RESULTS: OHRQoL and chewing function significantly improved (p < 0.001) one month after MDI loading by the new RPDs and continued to improve over the observation period (p < 0.05). The OES also significantly improved (p < 0.001) and remained almost unchanged over the next three years (p = 0.440). CONCLUSION: Despite the limitations of this study, the MDI-retained RPD appears to be a viable treatment modality in contemporary prosthodontics from the patients' perspective.

Pediatric patients' reasons for visiting dentists in all WHO regions.

BACKGROUND: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the four oral health-related quality of life (OHRQoL) dimensions (4D) or areas in which oral disorders impact pediatric patients. Using their dentists' assessment, the study aimed to evaluate whether pediatric dental patients' oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. METHODS: Dentists who treat children from 32 countries and all WHO regions were selected from a web-based survey of 1580 international dentists. Dentists were asked if their pediatric patients with current or future oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. Proportions of all pediatric patients' oral health problems and prevention needs were computed. FINDINGS: Data from 101 dentists treating children only and 523 dentists treating children and adults were included. For 90% of pediatric patients, their current oral health problems fit well in the four OHRQoL dimensions. For 91% of oral health problems they intended to prevent in the future were related to these dimensions as well. Both numbers increased to at least 96% when experts analyzed dentists´ explanations of why some oral health problems would not fit these four categories. CONCLUSIONS: The study revealed the four fundamental components of dental patients, i.e., the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact) are also applicable for pediatric patients, regardless of whether they have current or future oral health concerns, and should be considered when measuring OHRQoL in the pediatric dental patient population.

In Vitro Comparison of Time and Accuracy of Implant Placement Using Trephine and Conventional Drilling Techniques Under Dynamic Navigation.

The aim of this randomized in vitro study was to compare the time and accuracy of implant-site preparation and implant placement using a trephine drill versus a conventional drilling technique under dynamic navigation. In total, 42 implants were placed in simulation jaw models with the 2 drilling techniques by 2 operators who had previous experience with dynamic navigation. The timing of each implant placement was recorded, and horizontal, vertical, and angulation discrepancies between the planned and placed implants were compared. There was no significant difference in time or accuracy between the trephine and conventional drilling techniques. Implant-site preparation with a single trephine drill using dynamic navigation was as accurate under in vitro experimental conditions as a conventional drilling sequence.

Nonmalignant Oral Disease--Specific Dental Patient-Reported Outcome Measures for Adult Patients: A Systematic Review.

OBJECTIVES: Dental patient-reported outcome measures (dPROMs) can be differentiated into outcome measures for all oral diseases, so-called disease-generic dPROMs, and measures for specific oral diseases, so-called disease-specific dPROMs. The aim of this systematic review was to identify the psychometrically validated nonmalignant disease-specific dPROMs for adult patients and the dental patient-reported outcomes (dPROs) they measure. METHODS: This systematic review searched Ovid MEDLINE, Embase, PsycINFO, and the Cochrane databases along with hand searching, through July 28, 2020, to identify original articles of English language, multi-item dPROMs for adult dental patients with a specific oral disease, condition, or oral manifestations of systemic diseases. We analyzed the questionnaires for content commonalities, the reference or recall period, and the dimensionality. RESULTS: We retrieved 4228 unique references and identified 34 questionnaires; of which, 31 questionnaires captured impacts from oral diseases or conditions and three from oral manifestations of systemic diseases. All questionnaires together contained 102 dPROMs, measuring 75 dPROs. Oral health-related quality of life was a broader dPRO, which was measured by 24 dPROMs. The 74 narrower dPROs were measured by 78 dPROMs. The dPRO names suggested that essentially four dPROs were measured: Oral Function (N = 19), Orofacial Pain (N = 7), Orofacial Appearance (N = 11), and Psychosocial Impact (N = 37). CONCLUSIONS: Many psychometrically validated tools (N = 102) are available to measure the impact of specific nonmalignant oral disease on patients. While these tools intend to measure the particular patient-perceived impact profile of the oral disease, all tools measure in essence only four, more general concepts - the dimensions of oral health-related quality of life.

Why Patients Visit Dentists - A Study in all World Health Organization Regions.

OBJECTIVE: The dimensions of oral health-related quality of life (OHRQoL) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the major areas where patients are impacted by oral diseases and dental interventions. The aim of this study was to evaluate whether dental patients' reasons to visit the dentist fit the 4 OHRQoL dimensions. METHODS: Dentists (N = 1580) from 32 countries participated in a web-based survey. For their patients with current oral health problems, dentists were asked whether these problems were related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact or whether they do not fit the aforementioned 4 categories. Dentists were also asked about their patients who intended to prevent future oral health problems. For both patient groups, the proportions of oral health problems falling into the 4 OHRQoL dimensions were calculated. RESULTS: For every 100 dental patients with current oral health problems, 96 had problems related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact. For every 100 dental patients who wanted to prevent future oral health problems, 92 wanted to prevent problems related to these 4 OHRQoL dimensions. Both numbers increased to at least 98 of 100 patients when experts analyzed dentists' explanations of why some oral health problems would not fit the four dimension. For the remaining 2 of 100 patients, none of the dentist-provided explanations suggested evidence against the OHRQoL dimensions as the concepts that capture dental patients' suffering. CONCLUSION: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact capture dental patients' oral health problems worldwide. These 4 OHRQoL dimensions offer a psychometrically sound and practical framework for patient care and research, identifying what is important to dental patients.

A systematic scoping review of oral health models.

PURPOSE: The purpose of this systematic scoping review was to identify, analyze, and compare existing generic oral health models in English scientific dental literature. METHODS: We conducted a literature search in five databases, Ovid Medline, Embase, PsycINFO, Cochrane, and Web of Science, using pre-determined inclusion and exclusion criteria and calculated the interrater agreement coefficient "prevalence-adjusted bias-adjusted kappa" (PABAK). We identified, reviewed, and displayed the generic oral health models in review tables. RESULTS: Of the 3498 references identified, 13 oral health models from seven countries met the inclusion criteria. The interrater agreement coefficient resulted in a ''substantial agreement'' (PABAK = 0.80). Ten of the 13 (77%) generic oral health models were developed in English-speaking countries. All models were multidimensional and contained from two to 12 dimensions. Four models presented linear conception, and we observed non-linear conception in six models. Authors presented the unidirectional or reciprocal relations between dimensions in six models, and five models, respectively. Two models did not show models' relation or conception. Researchers used only experts (N = 1), literature (N = 2), dental patients (N = 2), or general population subjects (N = 3), or a combination of these sources (N = 5) for development of their generic oral health models. Statistical analyses supported the majority of the models (N = 8). CONCLUSIONS: The identified 13 oral health models vary substantially in their characteristics. This systematic scoping review of generic oral health models provides a toolbox, from which dental researchers can choose the theoretical model they consider fit best their oral health concept they want to investigate. Ideally, the international dental community will come soon to an agreement of accepting one oral health model, and this will provide an opportunity for comparison of outcomes across studies and populations and thus elevate dentistry to a higher evidence-based level.

Exploring training dental implant placement using computer-guided implant navigation system for predoctoral students: A pilot study.

INTRODUCTION: Recent computer-guided dynamic navigation systems promise a novel training approach for implant surgery. This study aimed to examine learning progress in placement of dental implants among dental students using dynamic navigation on a simulation model. MATERIALS AND METHODS: Senior students with no implant placement experience were randomly assigned five implant placement attempts involving either three maxillary or four mandibular implants distributed in the anterior/posterior, and left/right segments. Implant placement was planned using a Navident Dynamic Guidance system. Surgical time was recorded. Horizontal, vertical and angulation discrepancies between the planned and placed implant positions were measured using superimposed CBCT scans. Data were analysed with repeated measures regression with Tukey's adjusted pairwise comparisons (α = 0.05). RESULTS: Fourteen students participated, with a mean age of 26.1 years and equal males and females. Mean time for implant placement was associated with attempt number (P < 0.001), implant site (P = 0.010) and marginally related to gender (P = 0.061). Students had a significant reduction in time from their first attempt to their second (10.6 vs 7.6 minutes; adjusted P < 0.001) then plateaued. Overall 3D angulation (P < 0.001) and 2D vertical apex deviation (P = 0.014) improved with each attempt, but changes in lateral 2D (P = 0.513) and overall 3D apex deviations (P = 0.784) were not statistically significant. Implant sites were associated with lateral 2D, 2D vertical and overall 3D apex deviation (P < 0.001). DISCUSSION: Males were marginally faster than females, had slightly lower overall 3D angulation, and reported higher proficiency with video games. Novice operators improved significantly in speed and angulation deviation within the first three attempts of placing implants using dynamic navigation. CONCLUSION: Computer-aided dynamic implant navigation systems can improve implant surgical training in novice population.

Patient-Reported Outcome Measures for Adult Dental Patients: A Systematic Review.

OBJECTIVES: Patient-reported outcomes (PROs) are used beside disease-oriented outcomes (eg, number of teeth, clinical attachment level) to better capture the impact of diseases or interventions. To assess PROs for dental patients (dPROs), dental PRO measures (dPROMs) are applied. The aim of this systematic review was to identify generic dPROMs for adult patients and the dPROs. METHODS: This systematic review searched the MEDLINE, Embase, and PsycINFO databases along with hand searching, through December 2017, to identify English-language, multi-item dPROMs that are oral health generic, that is, they are applicable to a broad range of adult patients. RESULTS: We identified 20 questionnaires that contained 36 unique dPROs. They were measured by 53 dPROMs. dPRO names (N = 36) suggested they could be grouped into four dPRO categories: (1) Oral Function (N = 11), Orofacial Pain (N = 7), Orofacial Appearance (N = 3), and Psychosocial Impact (N = 14), as well as an additional dPRO that represented perceived oral health in general. Only eight questionnaires had a specific recall or reference period. dPROM's score dimensionality was only investigated in 13 of the 20 questionnaires. CONCLUSIONS: The identified 36 dPROs represent the major aspects of an adult dental patient's oral health experience; however, four major dPRO categories, that is, Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact, summarize how patients are impacted. If multi-item, oral health-generic dPROMs are to be used to measure patients' suffering, the 53 dPROMs represent current available tools. Limitations of the majority of these dPROMs include incomplete knowledge about their dimensionality, which affects their validity, and an unspecified recall period, which reduces their clinical applicability.

A 7-day recall period for a clinical application of the oral health impact profile questionnaire.

OBJECTIVES: Aims were to investigate and compare the validity and reliability of Oral Health Impact Profile (OHIP) scores referencing 7-day and 1-month recall periods in international prosthodontic patients. MATERIAL AND METHODS: A sample of 267 patients (mean age = 54.0 years, SD = 17.2 years, 58 % women) with stable oral health-related quality of life was recruited from prosthodontic treatment centers in Croatia, Germany, Hungary, Japan, Slovenia, and Sweden. These patients completed the OHIP on two occasions using a new 7-day recall period and the traditional 1-month recall period. OHIP score validity and reliability were investigated with structural equation models (SEMs) that included OHIP(past 7 days) and OHIP(1 month) latent factors and single indicator measures of global oral health status. The SEMs assessed measurement invariance and the relative validities of the two OHIP latent factors (representing the two recall periods). RESULTS: The SEMs provided cogent evidence for recall period measurement invariance for the two OHIP forms and equal validities (r = .48) with external measures of global oral health status. CONCLUSION: When assessed in international prosthodontic patients, OHIP scores using the new 7-day recall period were as reliable and valid as the scores using the 1-month recall period. CLINICAL RELEVANCE: Conceptual advantages make a 7-day recall period a preferred frame of reference in clinical applications of the OHIP questionnaire.

Exploration of dimensionality and psychometric properties of the Pittsburgh Sleep Quality Index in cases with temporomandibular disorders.

BACKGROUND: This study assessed the dimensional structure of sleep quality with the Pittsburgh Sleep Quality Index (PSQI) and investigated its psychometric properties in cases with temporomandibular disorders (TMD). METHODS: A convenience sample of 609 TMD cases (age: 37.1 ± 13.1 yrs, 18-67 yrs, 85% female) of the multi-center Validation Project meeting Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and with sufficient PSQI data were included in this study. To investigate PSQI scores' dimensionality, exploratory factor analysis was used. Factors were identified using the Scree plot. To investigate internal consistency, Cronbach's alpha was calculated. Analyses were separately performed for TMD cases with (N = 496) and TMD cases withouta pain-related diagnosis (N = 113). RESULTS: The mean PSQI score for all TMD cases was 7.1 ± 4.0 units, range: 0-19. The exploratory factor analysis identified one factor for cases with at least one pain-related TMD diagnosis as well as one factor for cases with a pain-free TMD diagnosis that explained 41% of the variance in cases with pain-related TMD and 37% in cases with pain-free TMD. Internal consistency for PSQI scores was alpha of 0.75 in cases with pain-related TMD, alpha of 0.66 in cases with pain-free TMD and alpha = 0.75 for all TMD cases. CONCLUSIONS: Sleep quality in TMD patients is a unidimensional construct and can therefore be represented by one summary score; a finding that is in line with previous reports in TMD patients.

Dental silicate ceramics surface modification by nonthermal plasma: A systematic review.

OBJECTIVES: Nonthermal atmospheric or low-pressure plasma (NTP) can improve the surface characteristics of dental materials without affecting their bulk properties. This study aimed to systematically review the available scientific evidence on the effectiveness of using NTP for the surface treatment of etchable, silica-based dental ceramics before cementation, and elucidate its potential to replace the hazardous and technically demanding protocol of hydrofluoric acid (HF) etching. METHODS: A valid search query was developed with the help of PubMed's Medical Subject Headings (MeSH) vocabulary thesaurus and translated to three electronic databases: PubMed, Web of Science, and Scopus. The methodological quality of the studies was assessed according to an adapted version of the Methodological Index for Non-Randomized Studies (MINORS). RESULTS: Thirteen in vitro study reports published between 2008 and 2023 were selected for the qualitative and quantitative data synthesis. The implemented methodologies were diverse, comprising 19 different plasma treatment protocols with various device settings. Argon, helium, oxygen, or atmospheric air plasma may significantly increase the wettability and roughness of silicate ceramics by plasma cleaning, etching, and activation, but the treatment generally results in inferior bond strength values after cementation compared to those achieved with HF etching. The technically demanding protocol of plasma-enhanced chemical vapor deposition was employed more commonly, in which the surface deposition of hexamethyl disiloxane with subsequent oxygen plasma activation proved the most promising, yielding bond strengths comparable to those of the positive control. Lack of power analysis, missing adequate control, absence of examiner blinding, and non-performance of specimen aging were common methodological frailties that contributed most to the increase in bias risk (mean MINORS score 15.3 ± 1.1). SIGNIFICANCE: NTP can potentially improve the adhesive surface characteristics of dental silicate ceramics in laboratory conditions, but the conventional protocol of HF etching still performs better in terms of the resin-ceramic bond strength and longevity. More preclinical research is needed to determine the optimal NTP treatment settings and assess the aging of plasma-treated ceramic surfaces in atmospheric conditions.

Factors related to oral health related quality of life in TMD patients.

The aims of the study were to determine the impact of temporomandibular disorders (TMD) on self-percieved oral health related quality of life (OHRQoL) and to compare OHRQoL of patients with TMD with a control group. A total of 81 TMD patients participated in a study group and 400 adults served as the control group. The mean OHIP summary scores were computed for all patients with the same diagnosis and the same subgroup of axis I according to the RDC/TMD exam form. The mean OHIP subscores for all seven domains of the OHIP questionnaire were compared between the study and the control group. The hierarchical linear regression model was used to assess the most important variables according to the RDC/TMD protocol that contribute to OHRQoL in TMD patients with the OHIP summary score as dependent variable. According to this study, TMD had a high association with reduced OHRQoL (p < 0.001). More diagnoses of axis I according to the RDC/TMD protocol (p < 0.001), higher age of TMD patients (p < 0.001) and diagnoses associated with limited jaw movements contributed to more impaired OHRQoL (p = 0.008 and p = 0.030, respectively). Female TMD patients had no significantly different OHRQoL compared to male patients (p = 0.436). According to regression analysis, higher age (p < 0.001), more physical diagnoses (p = 0.018) and diagnosis Ib (p = 0.169) explained 39.1% of the variability (p < 0.001) of the OHIP summary score in TMD patients.

A 3-year longitudinal study of quality-of-life outcomes of elderly patients with implant- and tooth-supported fixed partial dentures in posterior dental regions.

BACKGROUND: Clinical studies have mainly been focused on oral health-related quality-of-life (OHRQoL) outcomes of removable dentures. OBJECTIVE: To evaluate therapy of elderly patients with implant-supported fixed partial dentures (IFPD) and tooth-supported fixed partial dentures (FPD) in the posterior dental regions. PATIENTS AND METHODS: The OHIP49 was used to measure OHRQoL in 64 patients with IFPD and 38 patients with FPD, before, 3 weeks and 3 years after rehabilitation. A control group (CG) consisted of 62 individuals. RESULTS: The Oral Health Impact Profile questionnaire (OHIP) follow-up scores of the patients with FPD and the patients with IFPD were significantly smaller in comparison with the baseline scores (p < 0.01). The OHIP scores were further reduced at the 3-year follow-up. The patients with IFPD had significantly higher scores than the patients with FPD and the CG at the baseline and at the follow-ups. In the patients with FPD, both age groups (≤60 and >60) showed equal improvement of the OHRQoL. In the IFPD group, patients older than 60 years showed better improvement (p < 0.05). There were no significant differences dependent on gender and antagonistic teeth (p > 0.05). CONCLUSION: The FPD and the IFPD treatment showed significant improvement of OHRQoL. The FPD treatment improved OHRQoL equally in both age groups, while the IFPD treatment improved OHRQoL better in older patients.

Headache Because of Problems with Teeth, Mouth, Jaws, or Dentures in Chronic Temporomandibular Disorder Patients: A Case-Control Study.

This study aimed to characterize self-reported headaches because of problems with the teeth, mouth, jaws, or dentures (HATMJD) in chronic patients with temporomandibular disorders (TMDs) in order to compare their results with those of TMD patients without such headaches and to investigate the associations of HATMJD with depression, anxiety, physical symptoms, oral behaviors, and sleep quality. We conducted a case-control study on consecutive chronic TMD patients referred to the University Medical Center of Ljubljana, Slovenia. A self-reported HATMJD was extracted from item #12 in the 49-item version of the Oral Health Impact Profile questionnaire. Axis II instruments of the Diagnostic Criteria for TMD (i.e., for screening of depression, anxiety, specific comorbid functional disorders, and oral behaviors) and the Pittsburgh Sleep Quality Index were used in this study. In total, 177 TMD patients (77.4% women; mean age: 36.3 years) participated in this study; 109 (61.6%) patients were classified as TMD patients with HATMJD. TMD patients with at least mild depressive and anxiety symptoms, with at least low somatic symptom severity, and a high number of parafunctional behaviors had more HATMJD. Parafunctional behavior and sleep quality were the most prominent predictive factors of the occurrence of HATMJD. TMD patients with HATMJD have more psychosocial dysfunction, a higher frequency of oral behaviors, and poorer sleep quality than TMD patients without such headaches.

Thorough clinical evaluation of skin, as well as oral, genital and anal mucosa is beneficial in lichen planus patients.

Lichen planus (LP) is a common mucocutaneous disease of unknown aetiology with various geographical prevalence, may be related to some serious disorders such as squamous cell carcinoma and often remains underdiagnosed. The aim of this retrospective study was to thoroughly determine localization and clinical characteristics of LP lesions in a cohort of 173 Slovenian patients in association to the presence of accompanying symptoms and history of potential stressful events. Isolated cutaneous lesions of LP were found in 56.6% and isolated oral LP in 3.5% of patients. Thirty-four percent presented orocutaneous LP, whereas genitocutaneous LP was noted in 1.2%, orogenito-cutaneous LP in 4% and orogenital LP in 0.5% of patients. Underlying stressful events were noted in 36 out of 137 (26.3%) patients. Despite obviously visible localization of the lesions various medical specialists should be familiar with LP and thoroughly examine the complete skin, as well as oral, genital and anal mucosa in each LP patient to avoid a delay in diagnosing this disease and possibly disclose a much serious underlying condition. Psychological support should be offered, if needed.

Frequency of Four-dimensional Oral Health Problems across Dental Fields - a Comparative Survey of Slovenian and International Dentists.

OBJECTIVES: To compare the frequency of patients' oral health problems and prevention needs among Slovenian and international dentists with the aim to validate the four oral health-related quality of life (OHRQoL) dimensions across six clinical dental fields in all World Health Organization (WHO) regions. METHODS: An anonymous electronic survey in the English language was designed using Qualtrics software. A probability sampling for Slovenia and a convenience sampling strategy for dentist recruitment was applied for 31 countries. Dentists engaged in six dental fields were asked to categorize their patients' oral health problems and prevention needs into the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact). Proportions of patients' problems and prevention needs were calculated together with the significance of Slovenian and international dentists' differences based on dental fields and WHO regions. RESULTS: Dentists (n=1,580) from 32 countries completed the survey. There were 223 Slovenian dentists (females: 68%) with a mean age (SD) of 41 (10.6) years and 1,358 international dentists (females: 51%) with a mean age (SD) of 38 (10.4). Pain-related problems and prevention needs were the most prevalent among all six dental fields reported by dentists; Slovenian (37%) and 31 countries (45%). According to Cohen, differences between Slovenia, the broader European Region, and 31 countries were considered non-significant (<0.1). CONCLUSION: According to the dentists' responses, the frequency of patients' oral health problems and prevention needs are proportionate between Slovenia and 31 countries, regionally and globally. The four OHRQoL dimensions can be considered universal across all dental fields.

A Combination of CAD/CAM-Fabricated Zirconia Milled Bars and a Gold-Electroplated Superstructure Framework for an Implant- Supported Overdenture: A Case Report.

A 54-year-old woman presented with severe maxillary resorption, which resulted in an unstable maxillary removable denture. Due to poor anatomical conditions, the prosthodontic solution posed for the patient was an implant-supported maxillary overdenture based on four implants. This report presents the detailed workflow for CAD/CAM-fabricated, individually milled zirconia bars and an electroplated superstructure framework for an implant-supported removable overdenture, which enabled good retention and an optimal esthetic result. A critical element in the present case was the production of electroplated secondary elements, which are highly precise, with a homogenous layer of gold. No retention loss was observed after 12 months in use.

Association Between Oral Health-Related and Health-Related Quality of Life.

OBJECTIVES: To investigate the correlation between the four dimensions of Oral Health-Related Quality of Life (OHRQoL) and Health-Related Quality of Life (HRQoL) constructs in a dental patient population. METHODS: A cross-sectional study carried out at HealthPartners, Minnesota, USA. This study is a secondary data analysis of available adult dental patients' data. The instruments used to assess the OHRQoL and HRQoL constructs were the Oral Health Impact Profile-version with 49 items (OHIP-49) and Patient-Reported Outcome Measures Information System (PROMIS) measures v.1.1 Global Health instruments Patient Reported Outcome Measures (PROMs), respectively. We used Structural Equation Modeling to determine the correlation between OHRQoL and HRQoL. RESULTS: Two thousand and seventy-six dental patients participated in the study. OHRQoL and HRQoL scores correlated with 0.56 (95%CI:0.52-0.60). The OHRQoL and Physical Health dimension of HRQoL correlated with 0.55 (95%CI:0.51-0.59). The OHRQoL and Mental Health dimension of HRQoL correlated with 0.51 (95%CI:0.47-0.55). When adjusted for age, gender, and depression, the correlation coefficients changed only slightly and resulted in 0.52 between OHRQoL and HRQoL Physical Health, and 0.47 between OHRQoL and HRQoL Mental Health. Model fit statistics for all analyses were adequate and indicated a good fit. CONCLUSIONS: OHRQoL and HRQoL overlap greatly. For dental practitioners, the OHRQoL score is informative for their patients' general health status and vice versa. Study results indicate that effective therapeutic interventions by dentists improve patients' OHRQoL as well as HRQoL.

The Croatian version of the Oral Health Impact Profile Questionnaire.

Purpose of this study was to develop a Croatian version of the Oral Health Impact Profile questionnaire (OHIP--CRO49), following the accepted cross-cultural adaptation technique guidelines. The original version was translated by using a forward-backward translation method. The psychometric properties of the OHIP-CRO49 were tested. To test the construct validity 163 randomly selected subjects and 26 prosthodontic patients participated. The construct validity was supported by the association between the OHIP-CRO49 sum-scores and the self-reported oral health and five oral disorders. The test-retest reliability was tested on 30 prosthodontic patients and 30 students, and it was supported by high intraclass correlation coefficients (r = 0.63 to 0.95). To test the internal consistency 163 randomly selected subjects (general population), 26 prosthodontic patients and 29 dental students participated, and it was supported by high Cronbach's alpha coefficients (0.60 to 0.97). The resposiveness was tested on 21 patients with a treatment demand (toothache), and was supported by a statistically significant mean OHIP-CRO49 score difference (from 108.48 to 27.57) and a high effect size (2.96 and 3.48). Adequate psychometric properties in a typical patients' population make the new instrument suitable for assessment of Oral health-related quality of life (OHRQoL) in Croatia.
