The MID of the OHIP is an important benchmark to assess individual and group treatment effects in prosthodontics and could be used to approach what is clinically significant in terms of patient-based outcomes.

Oral health-related quality of life (OHRQoL) is increasingly of interest in dentistry. The current internationally accepted instruments used to measure OHRQoL need to be cross-culturally adapted for use in other cultural environments. It was the aim of the present study to develop a Hungarian version of the Oral Health Impact Profile (OHIP-H) following accepted guidelines. The original English-language version was translated into Hungarian, back-translated into English, and tested for its psychometric properties. Construct validity was tested on 144 prosthodontic patients and 200 randomly selected subjects. A priori hypothesized associations between OHIP summary scores and self-reported oral health and six self-reported oral conditions were investigated. The pattern of the observed associations supported the new instrument's construct validity. Responsiveness tested in 28 oral surgery patients was indicated by a statistically significant mean OHIP score change from 39.2 to 23.0. Test-retest reliability was demonstrated by intraclass correlation coefficients of 0.81-0.90 for OHIP summary scores and subscales in 31 prosthodontic patients. Cronbach's alpha values between 0.71 and 0.96 proved to have high internal consistency. Adequate psychometric properties in typical patient populations make the new instrument suitable for assessment of OHRQoL in Hungary.

The purpose of this study was to locate the 3D spatial position mandibular cast and determine its occlusal contacts in a novel way by using an intraoral scanner as part of the virtual occlusal record procedure. This study also analyzes the requirements in quantity and dimensions of the intraoral virtual occlusal record. The results showed that the best section combination consists of 2 lateral and frontal sections, the width of this section being that of 2 teeth (24 mm × 15 mm). This study concluded that this procedure was accurate enough to locate the mandibular cast on a virtual articulator. However, at least 2 sections of the virtual occlusal records were necessary, and the best results were obtained when the distance between these sections was maximum.

This insight into patients' perceived oral health provided by OHIP item profiles may be important for patient diagnosis and outcome assessment in the clinical setting.

Sufficient psychometric properties of the OHIP-A make the instrument suitable for assessment of oral health-related quality of life in Saudi Arabia.

Age and sex characteristics of different signs and symptoms of mandibular dysfunction were studied in 600 randomly selected urban persons. With regard to mandibular mobility marked differences were observed between the sexes, and a steady decrease parallel with ageing. Against this, the percentages of the objective dysfunction signs of impaired mobility and TMJ-sounds, as well as those of the pooled percentages of all the objective signs (Di-I + II + III), increased parallel with ageing. The percentages of headache occurrence peaked in different age groups for men and women. Statistically significant correlations were found between headache, parafunctions, stress, age, the existence of a preferred chewing side, as well as several dental-occlusal factors, and the prevalence of mandibular dysfunction; between Ai and Di according to Helkimo, and between excessive tooth wear and parafunctions.
