Association of cephalometric changes after 5 years of complete dentures wearing and oral health-related quality-of-life

Comparison of Three Prosthodontic Treatment Modalities for Patients with Periodontally Compromised Anterior Mandibular Teeth: A 2-year follow-up study

OBJECTIVES

To prospectively assess self-perceived chewing function (CF) and oral health-related quality of life (OHRQoL) in geriatric patients after receiving three different treatment modalities in the mandible: removable partial denture (CD-RPD), complete denture (CDs), or complete overdenture supported by mini dental implants (CD-MDI). At baseline, all patients had mobile anterior teeth (1 mm or >) and missing posterior teeth in the mandible. Patients were completely edentulous in the maxilla. After treatment, patients were recalled at the 3-month and the 2-year post-treatment period.

MATERIALS AND METHODS

A total of 176 patients participated (CD group, n=68; CD-RPD group, n=58; CD-MDI group, n=50). Self-reported CF was assessed using the Chewing Function questionnaire (CFQ), The OHRQoL was evaluated using the OHIP14 questionnaire, which the patients completed 1. before treatment, 2. three months after treatment, and 3. at the 2-year post-treatment stage.

RESULTS

The OHRQoL and the self-perceived CF significantly improved in all groups after treatment (p<0.01). The highest improvement of a CF was recorded in the CD-MDI group. The OHRQoL was significantly higher in the CD-MDI group in comparison to the CDs group after treatment (p<0.01). At the 2-year post-treatment stage, self-perceived CF significantly further improved in the CD-MDI group, while it worsened in the CD and the CD-RPD groups (p<0.01). The same pattern was recorded for the OHIP14 summary scores. The highest amount of denture repairs and adjustments was recorded in the CD-RPD group, although maintenance was also demanding in the CD-MDI group.

CONCLUSION

Within the limitations of this study, rehabilitation with mandibular MDI retained overdenture can be considered as preferred treatment with the constant improvement of OHRQoL and a chewing function in comparison to mandibular CD or mandibular RPD option in patients with mobile anterior mandibular teeth.

Short-Term Assessment of the OHIP-14 Scale on Denture Wearers Using Adhesives

PURPOSE

The purpose of this study was to assess differences of the Oral Health Implant Profile-14 (OHIP-14) scale over a month and determine association with gender, supporting tissues (KIS), and denture base (KID) among patients wearing complete dentures using denture adhesives.

MATERIALS AND METHODS

Sixteen denture wearers, candidates for a new set of complete dentures, were selected. OHIP-14 scores were recorded at the beginning of the study, 6 weeks after fitting of the new set (T0 ), 15 days (T1 ), and finally 30 days (T2 ) after daily use of a denture adhesive as instructed. The KIS and KID were clinically examined and rated according to the Kapur Index. Statistical analyses were based on repeated-measures ANOVA, Mann-Whitney test, regression analysis, and Friedman test at a = 0.05.

RESULTS

The OHIP-14 scale was found to have a high reliability (alpha = 0.847) and a high test-retest consistency (ICC = 0.889); however, domain 1 had the lowest item-total correlation (rho = 0.144) and item 7 a negative one (rho = -0.414). Trend analysis indicated a significant negative linear trend over time (slope = -3.156, p = 0.002), while repeated-measures ANOVA showed differences in OHIP-14 between T2 and T1 (p = 0.003) or T0 (p = 0.005) intervals. OHIP-14 groups were found to be positively associated with KIS (p = 0.010) and negatively with KID (p = 0.047) groups, but not with gender (p = 0.272).

CONCLUSIONS

The study shows that OHIP-14 has a high internal reliability and consistency when applied to new denture wearers, and its score decreases if denture adhesives are used for at least 15 days. Low KIS and high KID contributes to this trend. Some OHIP-14 items are more associated than others with the total score trend over time.
