“…Rothman (32) states that normal speech production depends on proper functioning of five essential mechanisms: 1) motor, consisting of the lungs and associated musculature, 2) vibrator -vocal cords, 3) resonator, consisting of oral, nasal, pharyngeal cavities and paranasal sinuses, 4) initiator, consisting of the motor speech area of the brain and 5) articulators. Articulators can be divided into static or passive (teeth, hard palate, and alveolar ridge) and dynamic or active (tongue, lips, soft palate or velum) components (4,35,45). Teeth and the above mentioned structures take part in performing the functions of oral cavity such as mastication and speech production.…”

Summary The prevalence of edentulism among Latvian population is high. According to the World Health Organization criteria complete tooth loss is regarded as a disability. One of the basic oral cavity functions is taking part in speech production. Alterations in oral cavity, caused by tooth loss and resorption of its supporting alveolar ridge, can produce changes in speech quality and intelligibility. This can lead to psychological and social problems, thus decreasing the patient’s quality of life. There are several options in replacing missing teeth. In Latvia prosthetic rehabilitation with removable dentures is in great demand. It is mentioned in literature, that removable dentures improve speech quality and intelligibility. However, there is no consensus in this field. The objective of this review is to screen literature for data related to the assessment of speech quality and intelligibility after replacement of lost teeth with removable dentures. Literature was selected through several electronic databases, as well as a manual search in dental journals. The detailed analysis of thirty two articles was performed and some significant facts were revealed. There exists an opinion, that removable dentures may have a negative effect on speech production. As the volume of oral cavity is diminished, resonation of oral cavity is decreased. Artificial teeth, removable denture base can limit tongue space and change the location of its articulation contacts. The assessment of speech quality and intelligibility is an essential diagnostic tool before and after prosthetic rehabilitation in order to provide the best option for restoring lost function. A standardized method for determining changes in speech quality after tooth loss and further prosthodontics has not yet been established. Semi-standardized instruments for the analysis of speech disorders are well documented when dealing with speech changes before and after prosthetic rehabilitation with various oral osseointegrated implant supported prostheses. For the Latvian language this method has not been described yet.

Speech, as formulated, perceived and decoded, is unique to humans. Speech is a learned process which makes use of the anatomical structures designed primarily for deglutition and respiration. The production of sounds requires selective modification and control of an outgoing air stream, which originates from the respiratory apparatus. Speech is a very sophisticated autonomous and unconscious activity. Speech in matured man in a learned habitual neuromuscular pattern which makes use of anatomical structures designed primarily for respiration and deglutition. Because oro-dental morphological features also may influence an individual speech, the dentist should therefore recognize the possible role of prosthetic treatment on speech activity. The loss of teeth and supporting structures alters the main articulatory cavity and produces a marked effect on the speech pattern proportionate to the location and magnitude of alterations. An empiric approach to the phonetic factor in denture construction frequently places the burden for compensating for speech changes for the adaptability of the tongue. Additionally, significant is the fact that the speech mechanism is highly susceptible to degenerative diseases. If dentures are to contribute effectively to the functions of speech, dentists should utilize studies in the speech science field to augment their clinical knowledge of the phonetic factor in denture construction.

“…A microphone produces a time-varying electrical voltage that is proportional to the increase or decrease in local pressure that constitutes sound. This continuous time-varying voltage is an electric analog of the acoustic signal [ 15 ]. The patients were asked to sit in upright position to allow reading of a passage in comfortable amplitude and pitch.…”

Objective. To investigate the influence of reproduction of different thickness and palatal rugae materials on complete dentures speech using Computerized Speech Lab (CSL) (spectrogram). Materials and Methods. Three completely edentulous male patients (aged 50–60 years) were selected for reading a paragraph. Twelve upper dentures were constructed, four for each patient. The patients' speech groups were divided into five groups, Group I: patients without dentures; Group II: patients rehabilitated with conventional acrylic dentures; Group III: patients with conventional acrylic dentures with rugae reproduction; Group IV: patients with dentures with metallic framework of minimal thickness and direct ragged metallic palatal surface at rugae area; Group V: patients with dentures with palatal rugae constructed from resilient acrylic resin material with thickness less than conventional denture. Speech samples were recorded after insertion of each denture for groups using Computerized Speech Lab (CSL) (spectrogram). The sounds selected were lingopalatal /s/z/sh/t/d/ and /l/. Results. Group III produced high mean significant difference with /sh/t/ sound. For Group IV, the difference was noticed with /s/z/sh/t/ and /d/ sounds, while for Group V the difference was shown with /z/l/ sound (P < 0.05). Conclusion. It is recommended to reproduce the rugae area in complete denture because the phonetic quality of complete denture with rugae is superior to the conventional denture.
