REVIEW
Sophie Miquel, Marcelo Aspiras, Jon E L Day
There is a growing body of literature which suggests that oral health and mastication can influence cognitive and systemic health during aging. However, it is currently unclear whether oral health, masticatory efficiency, cognitive health and systemic health merely deteriorate independently with age, or whether mechanisms exist linking mastication to cognitive and systemic health directly. The aim of this paper is to review the extent to which reduced mastication influences cognitive and systemic health during aging because this knowledge may underpin future interventions that improve quality of life...

Ameloblastoma is an aggressive odontogenic tumor which typically occurs between third and fourth decade of life that often needs resective approach. Immediate reconstruction may show better results. The treatment of multicystic ameloblastoma in the mandible being a rare case that occurred in the late second decade of life, which was surgically removed along with the affected teeth with safety margins, and the region was immediately reconstructed using a vascularized graft, removed from the fibula. Its integration, in combination with osseointegrated dental implants and fixed implant-supported prostheses, restored chewing function and esthetics...

Broad similarities in the timing of jaw adductor activity driving jaw movements across distantly related and morphologically disparate species have led to the hypothesis that mammalian masticatory motor patterns are conserved. However, some quantitative analyses also suggest that masticatory motor patterns have evolved in concert with dietary and/or morphological specialization. Here, we assess this relationship in two closely related carnivoran species with divergent diets and morphology: carnivorous ferrets and frugivorous kinkajous...

Skull shape convergence is pervasive among vertebrates. Although this is frequently inferred to indicate similar functional underpinnings, neither the specific structure-function linkages nor the selective environments in which the supposed functional adaptations arose are commonly identified and tested. We demonstrate that nonfeeding factors relating to sexual maturity and precipitation-related arboreality also can generate structure-function relationships in the skulls of carnivorans (dogs, cats, seals, and relatives) through covariation with masticatory performance...

Self-reported measures of oral health are often used to assess oral health in populations or groups, but their validity or reliability needs repeated confirmation. The objective of this cross-sectional study was to evaluate the validity of self-reported tooth counts and masticatory status, using data obtained from a sample of Japanese adults. A total of 2,356 adults aged 40 to 75 years participated in a questionnaire survey and a clinical oral examination from 2013 through 2016. Self-reported measures were compared with clinically measured values...

INTRODUCTION: Zygomatic implant placement can be the best option for restoring masticatory function of an extremely atrophic upper jaw, but the procedure is more invasive than conventional implant placement and can be associated with complications. PRESENTATION OF CASE: We report a complication that occurred during a secondary corrective surgical procedure four years after zygomatic implant placement. The patient was a 54-year-old female who had been edentulous for 25 years...

OBJECTIVES: The esthetic and functional results of orthognathic surgery of severe dentofacial deformities are predictable, however there are differences regarding the effects on stomatognathic system. The aim was to investigate the effects of orofacial myofunctional therapy (OMT) on the masticatory function in individuals with dentofacial deformity submitted to orthognathic surgery (OGS). MATERIAL AND METHODS: Forty-eight individuals (18-40 years) were evaluated, 14 undergoing OMT (treated group-TG), 10 without this treatment (untreated group-UTG) and 24 in a control group with normal occlusion; for clinical aspects the data of an individual was missed (n=46)...

Osteogenesis Imperfecta (OI) is a rare autosomal dominant connective tissue disorder in wich, the bone quality and density is affected. OI includes some metabolic disorders and have a wide range of clinical presentations. In Osteogenesis Imperfecta bone has a very low density and it is a disorder currently treated with bisphosphonates. Quality and quantity of bone is important for establishment of osseointegration in dental implants. There are few reported cases in the literature. This is a case report of a 61 year-old man with grade IV OI, rehabilitated with implant-supported fixed prostheses in the posterior right and left mandible, whithout bone grafts...

Gingival enlargement refers to any increase in the size of normal gingiva. The gingiva may be enlarged in response to various interactions between the host and the environment. It can be of various types including inflammatory, drug induced, associated with systemic disease, neoplastic, false, and idiopathic. Idiopathic gingival enlargement is a rare condition of undetermined etiology. The enlargement can be localized or generalized to entire dentition and is usually associated with the emergence of the teeth into the oral cavity and may regress after extraction...

OBJECTIVE: Oroalimentary automatisms (OAAs) resembling normal alimentary behavior are stereotyped complex movements that may occur during epileptic seizures. They are considered common clinical signs in temporal lobe seizures, but their anatomofunctional mechanisms are not established. We took the opportunity of presurgical intracerebral recordings to study the relations between the occurrence of OAAs and temporal/spatial features of ictal activities. METHODS: We retrospectively reviewed patients with medically intractable medial temporal lobe epilepsy who underwent stereoelectroencephalography (SEEG) at Cleveland Clinic between 2009 and 2016...

Most of the tools and diagnosis models of Masticatory Efficiency (ME) are not well documented or severely limited to simple image processing approaches. This study presents a novel expert system for ME assessment based on automatic recognition of mixture patterns of masticated two-coloured chewing gums using a combination of computational intelligence and image processing techniques. The hypotheses tested were that the proposed system could accurately relate specimens to the number of chewing cycles, and that it could identify differences between the mixture patterns of edentulous individuals prior and after complete denture treatment...

BACKGROUND: The term decreased occlusal vertical dimension refers to the reduced distance between two anatomical points while the teeth are in a state of occlusion. The development of this situation is about some parafunctional activities of the masticatory system. AIM: To evaluate the value of decreased occlusal vertical dimension in cases with temporomandibular disorder and to follow up the influence of corrective treatment with occlusal splints and definitive prosthetic construction upon the elimination of clinical symptoms...

In the elderly, masticatory function often presents failure in certain oral tasks due to impairment such as decline in muscular force, jaw or tongue motility, neuro-muscular coordination, tooth damage, malocclusion and saliva production. Great disparity is observed in the various and potentially cumulative oral declines that occur with ageing. Such difficulties may have an impact on food consumption and nutritional status. To obtain better understanding of the consequences of several oral deficiencies, a series of swallowable boluses were prepared in vitro with the AM2 masticator apparatus with normal and deficient programming...

A 28-year-old man presented to the emergency room complaining of right proptosis. He also manifested eye pain and facial fullness and redness in this side. Seven years ago, he had right hemifacial gunshot trauma treated with surgical reconstruction. The CT scan showed expansion of the right maxillary sinus due to a hypodense nonenhancing lesion extending to the nasal cavity, masticatory space, and extraconal space of the orbit. MRI was performed showing high signal intensity of the lesion on T2-weighted images indicating a cystic nature...
