To compare and evaluate House classification and graphoanalysis for the assessment of emotional status of complete denture patients. Fifty complete denture patients were included in the study. These patients were classified according to House classification as philosophical, exacting, indifferent and hysterical based on their behaviour during the course of the complete denture fabrication. Handwriting samples of these patients were obtained independently and the patient's emotional status was again classified by graphoanalysis. Statistical analyses like Chi-square, Spearman rank correlation, and Mann-Whitney U test were used to assess the expediency of both the methods in classifying complete denture patients. A significant correlation was found between results of graphoanalysis and those of clinical experience. Chances of observing highly difficult patients like hysterical were more from graphoanalysis than by clinical experience. Graphoanalysis is a useful tool for identification of difficult patients. Classification or categorization of patients by graphoanalysis and by clinical experience of patients differs significantly and graphoanalysis when coupled with clinical experience is more helpful in identification of difficult patients than merely by clinical experience alone.
Objectives: 1. To provide information about the subgingival microbiota around single tooth implants.2. To assess the subgingival microbial flora around the teeth adjacent to single tooth implants.3. To clinically evaluate the gingival health surrounding the single-tooth implants. Methods: Patients undergoing the single-tooth implant replacements, were selected as subjects for the study. The natural teeth adjacent to implant sites were taken as control sites. Clinically each peri-implant gingival tissue health was evaluated. Subgingival plaque samples were removed with sterile curette and evaluated for microbial flora, by microscopic examinations. Bacterial cultures of samples studied. The similar procedure was followed for the control sites also. Finally the data collected were statistically analyzed and interpreted. Results: The subgingival microbiota around single tooth implants was cultured and studied. Enterobacter species, Klebsiella pneumonia, Pseudomonas aeruginosa and Streptococcus species were predominantly found. Klebsiella pneumonia and Pseudomonas aeruginosa were found more frequently around implant sites than control sites. Anaerobic Bacteroides species were found in only one case around the implant site. Conclusions: Prevention and control of bacterial infection in the peri-implant region are among the key factors in determining the long term success or failure of dental implant therapy. The thorough knowledge about the subgingival microbiota around the healthy and diseased peri-implant mucosa is needed to determine the overall outcome of implant therapy.
The effects of rigid/non-rigid connectors and stress absorbing elements on mechanical behavior of TISP were studied using 2D finite element analysis. Finite element models were created in DISPLAY III software and were subjected to a static occlusal load of 75N. The use of non-rigid connector increased the stress (17.7 N/mm 2 ) on the implant neck when compared to rigid connector (10.25 N/mm 2 ) and stress absorbing element (8.49N/mm 2 ). Maximum displacement of the TISP (18.74 µm) was seen with a nonrigid connector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
