Impact of complete mouth rehabilitation following Pankey Mann Schuyler versus HOBO Philosophy on Oral Health-Related Quality of Life using Oral Health Impact Profile-14: A randomized clinical trial

AIM: Aim of this in vivo study was to assess the impact of two rehabilitation philosophies namely; Pankey Mann Schuyler (PMS) & Hobo Twin Stage (HOBO) on Oral Health-related Quality of life (OHRQoL) using Oral Health Impact Profile (OHIP 14). SETTINGS AND DESIGN: This was a randomized clinical trial. MATERIAL AND METHODS: This study was designed based on the PICOT model. 40 patients were selected who need to undergo complete mouth rehabilitation. The intervention performed was complete mouth rehabilitation therapy and the results were compared with that of no intervention. The outcome was assessed in terms of improvement in mastication, phonetics, esthetics and overall OHRQoL (OHIP-14) over a period of 01 year at intervals of 48 hrs, 01 mon, 6 mon and 12 months. Patients were unaware of the treatment philosophy being used and were given a questionnaire (OHIP-14); at baseline (pre-treatment) and 48 hrs, 1, 6 and 12 months after completion of treatment (post-treatment) to evaluate OHRQoL. The data was collected by independent reviewers blinded to the regimen followed making the participants and the outcome assessors blinded to the procedure. STATISTICAL ANALYSIS: Independent Student's t-test and Chi-Square test were used for analysis RESULT: Analysis illustrated significant differences in scores obtainedpre-treatment and post-treatmentin both groups at 12 months (P < 0.05). At 12 months, OHIP-14 scores showed a mean percentage change of 51% in Group A (PMS); (P = 0.001) and a mean percentage change of 49% in group B (Hobo). CONCLUSION: Complete mouth rehabilitation therapy for management of generalized attrition or mutilated dentition is a viable and effective treatment option and brings about definitive improvement in Oral Health Related Quality of Life (OHRQoL) and overall health status of an individual.
