Effect of Oral Hygiene Instruction on Maxillofacial Prosthetic Patients’ PCR （Plaque Control Record）

Abstract

Purpose: This study aimed to explore the effects of oral hygiene instruction on maxillofacial prosthetic patients’ oral hygiene conditions with plaque control record （PCR）.
Methods: Patients were divided into 3 groups. Group-1 included 38 maxillofacial prosthetic patients with continuous oral hygiene instruction by dental hygienists. Group-2 included 16 maxillofacial prosthetic patients who didn’t receive oral hygiene instruction. Group-3 included 35 non-maxillofacial defects patients with continuous oral hygiene instruction. Oral hygiene condition was calculated by O’Leary’s PCR. Patients’ age, residual teeth, occlusal supports, and occlusal units （OUs） were picked up as factors. Statistical analyses were performed using Kruskal-Wallis test, Steel-Dwass test, and Spearman’s rank correlation coefficient.
Results: Group-3 patients had significantly more residual teeth, occlusal supports and OUs compared to Group-1 and Group-2, although there was no significant difference in age among all groups. There were significant differences in PCR scores among all groups, Group-2 showed the highest PCR scores, and Group-3 showed lower than Group-1. In only Group-1, significant correlations were found between PCR and residual teeth, and occlusal supports.
Conclusions: Oral hygiene instruction and oral care could improve maxillofacial prosthetic patients’ oral hygiene conditions. However, it seems to be hard to reach the level of non-maxillofacial defects patients.
