Importance of Osseoperception and Tactile Sensibility during Masticatory Function in Different Prosthetic Rehabilitations: A Review

Background and Objectives: Tactile sensibility is an important characteristic for evaluating the masticatory efficiency in different occlusal situations. When a tooth is extracted, relevant proprioceptors from the periodontal ligament get lost; and after the rehabilitation of this abscess by means of oral prosthesis, this sensibility decreases influencing masticatory function. Osseoperception is a sensitive phenomenon associated with dental implants that allows an increased tactile sensibility to those wearing implant prostheses. The purpose of this study was to determine the difference in tactile sensibility values between implant prosthesis, complete dentures, and natural teeth through a review of the available literature. Materials and Methods. In order to dissect the information, 24 articles from 2004 to 2021 were analyzed from MEDLINE, PubMed Central, and Web of Science databases. These articles were directly related to measuring tactile sensibility in different situations and demonstrating the influence of osseoperception in an improved masticatory function. Results: Tactile sensibility in implant prosthesis is slightly reduced compared with natural dentition but presents improved values with regard to complete dentures. Conclusions: Implant prosthesis are more effective during masticatory function than complete dentures, as they present an increased tactile sensibility, very similar to that present in natural dentition. This enhanced sensibility in implants is due to the osseoperception phenomenon.

Active Tactile Sensibility of Brånemark Protocol Prostheses: A Case–Control Clinical Study

Few studies have assessed active tactile sensibility in patients rehabilitated with implants. Improved knowledge about functional tactile sensibility will contribute to several clinical applications, such as protocols for immediate loading, prosthesis design, occlusal improvement in implantology, and physiological integration of implant-supported prostheses. The present study evaluated active tactile sensibility in patients rehabilitated with Brånemark-type mandibular prostheses that impede the total mucosa-supported maxillary prosthesis. Thirty-five subjects participated in this study. The experimental group (n = 18) inclusion criteria were as follows: Brånemark-type prosthesis and a total mucosa-supported maxillary prosthesis. The control group (n = 17) was composed of participants with complete healthy dentition. Carbon foils with different thicknesses (12 μm, 24 μm, 40 μm, 80 μm, and 200 μm) were placed in the premolar region to evaluate the brink of active oral tactile sensibility. The researchers assessed the participants 120 times. After evaluation, we observed a statistical difference (p < 0.05) between the groups. Additionally, the degree of sensibility was found for all thicknesses, except for 12 μm, on both sides. There was a more significant increase in perception in the control group as the carbon thickness increased. The tactile sensibility threshold was 2.5 times greater for participants with prostheses. Thus, the tactile sensibility for mandibular implant-supported and maxillary mucosa-supported prostheses is significantly lower than that of dentate patients, which was detected above the thickness of 80 μm; in patients with natural dentition, different thicknesses were seen starting from 24 μm.

Estimulación de la lectoescritura en escolares con desviación del desarrollo intelectual

Las alteraciones del sistema nervioso que frecuentemente se asumen en la educación como desviaciones del desarrollo psíquico afectan considerablemente el curso del desarrollo de cada individuo en los diferentes períodos etarios. Las primeras manifestaciones intelectuales que desempeña el sujeto en su evolución hacia la madurez psíquica se manifiestan considerablemente desde las áreas de lenguaje y locomoción, siendo la lectoescritura y la psicomotricidad pares indisolubles en la actividad evolutiva de cada sujeto. En consideración a las características funcionales que se manifiestan en los individuos con alteraciones a nivel intelectual en el primer ciclo de la educación especial, la presente investigación se propone diseñar un cuaderno que estimule las habilidades de la lectoescritura en escolares con desviación del desarrollo intelectual. Como referentes metodológicos se promueve la observación mediante encuesta, la escala valorativa, pruebas psicopedagógicas descriptivas, los test de dominancia de funciones cerebrales y el test de integración funcional básica y el criterio de especialistas. Teniendo en cuenta el orden de criterios establecidos y los resultados obtenidos, se puede inferir que la estructura secuencial que promueve la propuesta sirve como referente de estudio aplicativo a diferentes alteraciones con el diagnóstico común de alteración en la grafomotricidad, ya que aúne los requisitos indispensables para estimular las áreas del lenguaje, sensibilidad táctil fina y gruesa, visuoconstrucción, así como las praxias y gnosias. Por lo que se considera una propuesta a tono con los reclamos de las adecuaciones de la educación rumbo a la equidad e igualdad de oportunidades desde una educación inclusiva y diversa. PALABRAS CLAVE: estimulación; lectoescritura; desviación; desarrollo intelectual. Stimulation of literacy in schoolchildren with borderline intellectual functioning ABSTRACT Deficits of the nervous system that frequently it is assumed in the education as deviations of the psychic development they affect considerably the course of the subject development in each different life periods. The first intellectual manifestation that plays the subject in its evolution towards the psychic ripeness is manifested considerably from the areas of language and locomotion, being the reading-writing and psychomotor areas the equal indissoluble in the evolutionary activity in the subject. Under consideration to the functional characteristics that it is manifested in the individuals with alterations at intellectual level in the first cycle of the special education, the investigation proposes design a notebook that stimulates the skills of the reading-writing in escolars with deviation of the intellectual development. As relating methodological promotes the observation by review, the evaluative scale, psychopedagogical descriptive taste, the test of dominium of cerebral functions and the test of functional basic integration and the specialists’ criteria. By keeping in mind, the order of criterions established and the results obtained, can infer to it that the sequential structure that promotes the proposal serves as relating of study applicative to different alterations with the common diagnosis of alteration in the graphic-motoric, since the indispensable requirements to stimulate the areas of the language, tactile sensibility dies and thick, visual construction, as well as praxis and gnosis. For which is considered a proposal in tune with the fittings of the education bound for the equity and equality of opportunities from an inclusive and diverse education.

Body temperature and esthesia in individuals with stroke

Patients with sequelae of stroke commonly report somatosensory losses. It is believed that body temperature may be associated with tactile sensibility and sensorimotor recovery of these patients. Demonstrate the associations among tactile sensibility, cutaneous temperature, subjective temperature perception, and sensorimotor recovery of patients with stroke sequelae. 86 patients with stroke sequelae were included. Patients had standardized regions of interest (ROIs) assessed with infrared thermography (FLIR T650SC) and monofilaments esthesiometry, and global motor recovery was evaluated with Fugl-Meyer Assessment (FMA). The presence of self-reported perception of temperature difference was used to divide the participants into two groups of 43 patients, and correlation tests were applied to establish correlations among variables. There is no clinically relevant association between tactile sensibility and cutaneous temperature of the foot, regardless of the subjective sensation of temperature changes. Sensorimotor recovery evaluated by FMA is associated with the difference of sensibility between both sides of the body (p < 0.001), as well as with the difference of tactile sensibility (p < 0.001). A clinically significant association between the difference of cutaneous temperature and tactile sensibility was not found, regardless of the presence or absence of subjective perception of such temperature difference. However, sensorimotor recovery is correlated with cutaneous temperature differences and tactile sensibility.

Liberature or Literature in the Electric Age

The article proposes a media-oriented approach to liberature, a literary trend born in Poland at the end of the 20th century which aims at reconsidering the physical body of the book as an integral part of the literary work. The idea of liberature is not only a contemporary literary programme, but it has also helped in redefining phenomena from the past hitherto considered to be marginal. The thesis of the article is that this corporeal turn is directly connected with what Marshall McLuhan has called the electric age – a time in which electrical media have put an end to print culture and consequently to the predominance of sight over other senses, to standardisation, specialisation, and linear thinking in favour of a new audio-tactile sensibility. Liberature, if considered from this point of view, turns out to be not a form of resistance of old print culture in a digital world, but the natural consequence of a change of paradigm we can trace also in other fields such as physics and linguistics where the concept of embodiment has occupied a central position for several decades. Hence, far from being a curiosity at the periphery of contemporary literature, it ought to be considered as an important expression of present times.

A REVIEW STUDY ON THE MODE OF ACTION OF KSHEERA DHOMA IN THE MANAGEMENT OF ARDITA (BELL’S PALSY)

Arditais a medical condition causing the Vakratha[deviation] of Mukha ardha and leads to facial asymmetry and malfunction. It occurs due to aggravated Vatadosha. It has been included in Vataja Nanatmaja Vyadhi. It can be correlated to facial palsy in modern which carries similar complaints to Ardita of deviation of half of the face with sensory & motor impairment on the affected side. Acharya Sushruta and Charaka mentioned Nadi sweda in the Ardita chikitsa sootra. The modified form of Nadisweda itself is Ksheera Dhooma. As there is a weakness of Facial nerve in Bell’s palsy and the same moist heat is indicated in Bell's palsy by modern medicine. This effect is ensured by Swedana and it has the capacity to stimulate the nerve centres and increases the tactile sensibility. It is seen that Ksheeradhooma is having good efficacy on Ardita. Keywords: Ardita, Ksheera dhooma, bell’s Palsy

Upper extremity sensory training after stroke

Introduction. Stroke is one of the leading causes for disability worldwide. After stroke, the majority of stroke survivors experience significant arm-hand impairments and a decreased use of the paretic arm and hand in daily life. Tactile sensibility of the hand is essential for identifying objects and for motor performance. Despite important sensory contributions to normal and abnormal movement, research has predominantly focused on motor aspects of stroke recovery. In this paper, we present the effect of sensory stimulation program on arm sensation and motor recovery in subacute stroke. Case outline. In a 65 years old woman the sensibility stimulation program was administered in subacute phase of post-stroke rehabilitation, six weeks after stroke, involving active and passive somatosensory intervention, motor control, coordination, strength and balance exercises. The rehabilitation protocol was applied for four weeks, five times a week. On discharge, the results of physiotherapy assessment showed full recovery of her right arm and hand. Conclusion. This case report shows that precise assessment, problems identification and problem oriented somatosensory interventions can improve, for short period, functional motor performance of the arm involved in rehabilitation after stroke.
