Influence of the Partial Denture on the Articulation of Dental and Postalveolar Sounds
Dental prosthesis is a foreign body in oral cavity and thus necessarily interferes with speech articulation. The purpose of this study was to examine influence of partial denture on speech quality and to show eventual differences in pronunciation of dental sounds c, z, s and postalveolar sounds č, ž and š. We have examined differences in pronunciation between subjects with removable partial dentures, the same group without partial dentures and a control group. The study was performed on 30 subjects with removable partial dentures and 30 subjects with complete dental arch. All subjects were recorded while reading six Croatian words containing the examined sounds. Recordings were analyzed with Multispeech Program (Kay Elemetrics Inc.). Acoustic analysis – LPC (linear prediction coding) provided formant peaks (Hz) for each examined sound, its intensity (dB) and formant bandwidths (Hz). Results showed that subjects with partial dentures had 50% less distorted variables and that prostheses did not completely restore articulation of postalveolar sounds. Groups with and without prostheses had lower formant peaks intensities and wider formant bandwidths in comparison to the control group. Partial dentures have not significantly interfered with resonance frequency. At the same time, pronunciation of the examined sounds was significantly improved.
However, precision of the articulation movements has deteriorated
A European perspective on auditory processing disorder-current knowledge and future research focus
Current notions of \u201chearing impairment,\u201d as reflected in clinical audiological practice,
do not acknowledge the needs of individuals who have normal hearing pure tone
sensitivity but who experience auditory processing difficulties in everyday life that are
indexed by reduced performance in other more sophisticated audiometric tests such
as speech audiometry in noise or complex non-speech sound perception. This disorder,
defined as \u201cAuditory Processing Disorder\u201d (APD) or \u201cCentral Auditory Processing
Disorder\u201d is classified in the current tenth version of the International Classification of
diseases as H93.25 and in the forthcoming beta eleventh version. APDs may have
detrimental effects on the affected individual, with low esteem, anxiety, and depression,
and symptoms may remain into adulthood. These disorders may interfere with learning
per se and with communication, social, emotional, and academic-work aspects of life.
The objective of the present paper is to define a baseline European APD consensus
formulated by experienced clinicians and researchers in this specific field of human
auditory science. A secondary aim is to identify issues that future research needs
to address in order to further clarify the nature of APD and thus assist in optimumdiagnosis and evidence-based management. This European consensus presents the
main symptoms, conditions, and specific medical history elements that should lead to
auditory processing evaluation. Consensus on definition of the disorder, optimum diagnostic
pathway, and appropriate management are highlighted alongside a perspective
on future research focus
