“…ocelusal sound waveform similar lo thai seen at baseline and 0-06 mm elevation. Muramoto et al (1989) have shown that the duration of oeelusal sounds in healthy subjects during tapping was 6-9 ms. Our findings support their results. Also, 0-06 mm FCDK elevation resulted in a 0-2 ms prolongation of occlusal sound.…”

“…Gnatbosonic studies by Watt (1966Watt ( , 1968Watt ( , 1970 revealed tbat elevations of a tooth up to OJ 0 mm can be compensated by the physiological mobility of ibe teeth whereas changes will occur above tbe limit. Muramoto et al (1989) revealed that occlusal sounds may also be used in assessing tissue destruction caused by periodontal diseases. Tbeir hypothesis was further consolidated by Taguchi et al (1990) who demonstrated that durations of tooth percussion sound signals are longer in patients with periodontitis than in healthy controls.…”

Occlusal sounds, contact timings and time moments were measured and analysed on 10 subjects onto whom an occlusal interference was created experimentally. A full-cast double crown was unilaterally set on the upper first molar of each subject, then gradually elevated for 0.06, 0.10, 0.20 and 0.30 mm by inserting a pre-calibrated metal folio. Occlusal sound was measured with an analyser designed for the purpose. Timings and time moments were analysed with a T-scan system. All measurements were performed at least 10 times per subject. The results showed that prolonged occlusal sound duration, changes in acoustic signal waveform and increased shift of the centre of effort were observed concomitantly with crown elevation. Differences in these values at 0.06 mm as compared with those at baseline were not statistically significant. This could be explained through a physiological compensation by the periodontal ligament. The differences with baseline were statistically significant from 0.10 mm ongoing. The distribution of occlusal conacts was determined by the use of a newly developed parameter. Referred to as 'Tap Score', the parameter consists of converting contact timings occurring in seven ranges into least-square-based weighted scores. Analysis of the tap score disclosed evident imbalance between the crowned and the non-crowned side starting from 0.10 mm elevation, whereby a forward shift of the major contact point was observed on the non-crowned side. Our study demonstrated that evident changes in gnathosonic and T-scan parameters are likely to occur at a crown elevation within a 0.06-0.10 mm range.(ABSTRACT TRUNCATED AT 250 WORDS)

A multiparametric analysis of occlusal and periodontal jaw reflex characteristics in young adults with normal occlusion

et al. 1997

Periodontal jaw reflex, duration of percussion sounds, tooth mobility, and time-moment analysis of occlusal contacts by the T-scan system was recorded in nine periodontally healthy volunteers. The results showed that (i) reflex responses to the pressure applied to the uppercentageral incisors in the lingolabial direction varied, depending on the background jaw-clenching force (BCF) of the same-sided first molars. The BCF levels to elicit excitatory reflexes were 6-8 Kgf, and inhibitory reflexes were clearly elicited with a BCF of 10 Kgf and beyond. (ii) Duration of percussion sounds via an occlusal sound analyser (4.73-4.84 mS: upper first molars, 4.89-5.00 mS: uppercentageral incisors) and tooth mobility using a 'Periotest' (3.3-3.5: upper first molars, 5.5-5.6: uppercentageral incisors) showed a normal value. (iii) The time moments of occlusal contacts were symmetrical toward the midsagittal axis of the occlusal plane. The centre of the anteroposterior occlusal contacts was located in the first molar regions.

Ten periodontally affected subjects and 10 healthy subjects were selected in order to examine the duration patterns of percussion sounds in all upper teeth, excluding the 8's. Probing depth, loss of attachment, tooth mobility by 'Periotest', bone loss and percussion sound duration via occlusal sound analyser were recorded during the pretreatment period. The following results were obtained from the study: (i) the normal duration of percussion sounds ranged from 4.40-5.33 ms; (ii) percussion sound values of periodontal patients were of longer duration than those of healthy subjects; (iii) a close correlation between duration and other individual parameters was found in all upper teeth, with the exception of molars.
