The Feasibility of Cross-Linguistic Speech Evaluation in the Care of International Cleft Palate Patients.

ABSTRACT: Many patients with cleft palate in developing countries never receive postoperative speech assessment or therapy. The use of audiovisual recordings could improve access to post-repair speech care. The present study evaluated whether English-speaking speech-language pathologists (SLPs) could assess cleft palate patients speaking an unfamiliar language (Tamil) using recorded media. Recordings obtained from Tamil-speaking participants were rated by 1 Tamil-speaking SLP and 3 English-speaking SLPs. Ratings were analyzed for inter-rater reliability and scored for percent correct. Accuracy of the English SLPs was compared with independent t tests and Analysis of Variance. Sixteen participants (mean age 14.5 years, standard deviation [SD] 7.4 years; mean age of surgery of 2.7 years, SD 3.7 years; time since surgery: 10.8 years, SD 5.7 years) were evaluated. Across the 4 SLPs, 5 speech elements were found to have moderate agreement, and the mean kappa was 0.145 (slight agreement). Amongst the English-speaking SLPs, 10 speech elements were found to have substantial or moderate agreement, and the mean kappa was 0.333 (fair agreement). Speech measures with the highest inter-rater reliability were hypernasality and consonant production errors. The average percent correct of the English SLPs was 60.7% (SD 20.2%). English SLPs were more accurate if the participant was female, under eighteen, bilingual, or had speech therapy. The results demonstrate that English SLPs without training in a specific language (Tamil) have limited potential to assess speech elements accurately. This research could guide training interventions to augment the ability of SLPs to conduct cross-linguistic evaluations and improve international cleft care by global health teams.

Stress distribution patterns of implant supported overdentures-analog versus finite element analysis: A comparative in-vitro study.

AIMS AND OBJECTIVES: The aim of this study was to asses & compare the load transfer characteristics of Ball/O-ring and Bar/Clip attachment systems in implant supported overdentures using analog and finite element analysis models. METHODOLOGY: For the analog part of the study, castable bar was used for the bar and clip attachment and a metallic housing with a rubber O-ring component was used for the ball/O-ring attachment. The stress on the implant surface was measured using the strain-gauge technique. For the finite element analysis, the model were fabricated and load applications were done in a similar manner as in analog study. RESULTS: The difference between both the attachment systems was found to be statistically significant (P<0.001). CONCLUSION: Ball/O-ring attachment system transmitted lesser amount of stresses to the implants on the non-loading side, as compared to the Bar-Clip attachment system. When overall stress distribution is compared, the Bar-Clip attachment seems to perform better than the Ball/O-ring attachment, because the force was distributed better.
