ABSTRACT
Aim: To evaluate the changes in temporomandibular joint (TMJ) vibrations after insertion of the complete denture in edentulous patients. Settings and Design: An observational in vivo study conducted to evaluate the changes in maximum mouth opening, total integrals, peak amplitude, and peak frequency in TMJ vibrations on the day of complete denture insertion and 6 months of follow up. Materials and Methods: Twenty patients (male: 12 and female: 8) were selected for the fabrication of balanced complete dentures following conventional procedure. Joint vibration analysis was recorded using the joint vibration analyzer. The patients were instructed to open as wide as possible and close to the intercuspal position with rhythmic speed following the metronome projected on the screen. The TMJ vibrations were amplified and displayed as waveforms in a graphical representation by system software. Statistical Analysis Used: Wilcoxon test. Results: A significant decrease in the total integral (P = 0.001) and peak amplitude (P = 0.044) for opening and closing movements of the left and right joints was observed. There was no significant change in maximum mouth opening (P = 0.624). A decrease in peak frequency was noted only at left opening movements between the day of insertion and at 6 months (P = 0.025). Conclusion: The function of TMJ mechanics was improved till 6 months after insertion of complete denture with balanced articulation (BA).

PURPOSE: An edentulous patient's psychosocial attributes that may have influence on the oral health-related quality of life (OHRQoL) are given little consideration in therapeutic care. The aim of this study was to assess the impact of complete denture therapy on overall OHRQoL in elderly edentulous patients. The possible role of the patient's initial expectation toward OHRQoL was also evaluated. METHODS AND MATERIALS: OHRQoL was assessed using the OHIP-EDENT psychometric instrument, and 56 patients participated in the study. The assessment was done at three time points including pretreatment, after 1 month, and after 6 months. Significant differences in the OHIP-EDENT scores between pretreatment to after 1 month and pretreatment to after 6 months were calculated using Wilcoxon Signed Rank test (p < 0.05). Mann-Whitney test was used to analyze the association of patient expectations with OHIP-EDENT scores. RESULT: Statistically significant improvement in OHRQoL after complete denture therapy at both 1 and 6 months postinsertion was evident. Statistically significant difference in the mean scores between the genders was observed after 6 months. There was no statistically significant difference in the levels of dysfunction, discomfort, and disability associated with oral problems between moderate and high expectation group at any time point. CONCLUSION: Elderly edentulous patients had an improved overall OHRQoL after complete denture therapy, and female patients had appreciably better OHRQoL than their male counterparts. A patient's initial expectation did not have significant influence on overall OHRQoL.

Contemporary research in acrylic denture base materials focuses on the development of a novel poly(methyl methacrylate) (PMMA) resin with antimicrobial properties. Although PMMA resin has fulfilled all the requirements of an ideal denture base material, its susceptibility to microbial colonization in the oral environment is a formidable concern to clinicians. Many mechanisms including the absence of ionic charge in the methyl methacrylate resins, hydrophobic interactions, electrostatic interactions, and mechanical attachment have been found to contribute to the formation of biofilm. The present article outlines the basic categories of potential antimicrobial polymer (polymeric biocides) formulations (modified PMMA resins) and considers their applicability, biological status, and usage potential over the coming years.

Individuals with Down syndrome (DS) are susceptible to severe periodontal disease, due to immune alterations related to functional defects of polymorphonuclear leukocytes and monocytes. The adjunctive use of locally delivered antimicrobials has been proven to be beneficial, especially in areas where mechanical therapy might fail. This article describes the management of a patient with DS who had aggressive periodontitis. The treatment used a local drug delivery system with tetracycline fibers as an adjunct to scaling and root planing.
