“…Although the somatosensory function of teeth is complex and is engaged not only for biting or chewing (Trulsson & Johansson 1996a, b) but also in the reflexes of the masticatory muscles (van Steenberghe 1979, Linden 1990) and oral stereognosis (Jacobs et al 1997), we wanted to use a pure tactile stimuli without interference with pain, temperature or motor‐related tasks. This precludes the use of electrical stimulation, which are painful or unpleasant (Ettlin et al 2004, Jantsch et al 2005), and motor task involving clenching (Yan et al 2008, Byrd et al 2009).…”

“…The stereognostic ability is the ability to recognize and to distinguish forms and sizes. When testing the oral stereognosis, it can be performed by only contacting with teeth (Jacobs, Bou Serhal & van Steenberghe, 1997) or manipulating by tongue intra‐orally (Müller et al ., 1995; Mantecchini et al ., 1998; Essick, Chen & Kelly, 1999). This will involve receptors not only inside the oral cavity (periodontal ligament, oral mucosa and periosteum), but also receptors in the vicinity structures such as the muscles, tendons and temporomandibular joints (for a review, see Jacobs et al ., 1998a).…”

The innervation of skin and oral mucosa plays a major physiological role in exteroception. It also has a clinical interest as illustrated by sensory changes after neurosurgical procedures. These sensory changes often rely only on the patients' subjective reports, although objective assessments are possible. This review compares the neurophysiological features of the trigeminal sensory pathways with those of cutaneous sensory innervation. In this review, three receptor groups will be discussed: mechanoreceptors, thermoreceptors and nociceptors. Differences between receptors in the glabrous skin, the hairy skin and the oral mucosa will be highlighted. Sensory testing devices have been developed to quantify psychophysiological parameters such as the threshold level for receptor activation upon mechanical stimulation, but such devices have been merely developed to determine the threshold of skin receptors (tactile, thermal). Later on, some have been adapted to suit the particularities of the oral environment. This review attempts to compare the available literature on test devices for oral versus cutaneous tactile function. It summarizes what is common or rather particular to the devices used to study either cutaneous or oral receptors.

“…Rehabilitation focused on restoring eating and swallowing functions is important. The highest priority in the rehabilitation of eating and swallowing functions is undoubtedly the improvement of the physical function; however, when considering QOL, recovery of the sensory function is also desirable (1–9). The dignity of an individual is maintained through the recovery of both the functions.…”

“…As the size and shape of an intra‐oral bolus of food provides oral sensory information important for eating and swallowing, in this study, we focused on the ability to recognize the size and shape of items placed in the mouth, and investigated the oral stereognostic ability, aiming at developing a rehabilitation method that targets recovery of the oral stereognositic ability. There is a wealth of research on oral stereognostic ability (1, 3, 4, 6, 14–19). However, these studies did not always apply the same method and were not analysed from the perspective of sensory impairment.…”

Rehabilitation of eating and swallowing functions from the viewpoint of quality of life should attempt to restore not only the physical, but also sensory function. As the size and shape of the intra-oral bolus of food provides oral sensory information important for eating and swallowing, we investigated the stereognostic ability of the tongue in 269 young adults (mean age: 24.5 years) and 60 seniors (mean age: 80.5 years); all of whom had no eating or swallowing complaints. Assessment of the stereognostic ability involved identifying 20 differently shaped test pieces placed in the oral cavity. The young adults identified a significantly higher number of differently shaped test pieces than the seniors (mean correct number of responses: 16.5 and 10.1 respectively; P < 0.001). Gender and the presence of palatal covers did not have any significant effect on stereognostic ability. The test pieces were categorized into six groups based on the shape. When the young adults misidentified a piece, they often selected another piece within the same group, almost never selecting a piece from another group. The seniors, however, chose test pieces from different groups. Moreover, to determine whether stereognosis could be improved through training, we conducted training involving four senior subjects in their 80s, who correctly identified 10 or fewer pieces. After the training, the number of correct answers increased significantly (P < 0.05). These findings indicate that seniors show decreased stereognostic ability of the tongue compared with young adults and suggest the possibility of recovering the ability using our training method.
