Familial gingival fibromatosis is a rare hereditary condition due to chromosomal abnormality which can occur as an isolated disease or as part of a syndrome and has an incidence of 1:350 000. This condition leads to esthetic, functional, psychological and masticatory disturbance of the oral cavity. Here, we present a case of 21-year-old female with severe enlargement of gums in maxilla and mandible. Deciduous teeth were erupted at normal age but the permanent teeth in the oral cavity were not erupted. Her grandmother, father and younger sister were also affected with the same condition...

Despite progress in dentistry, tooth loss in old age is still a reality, even more so in long-term-care residents. However, recent trends indicate that natural teeth are lost later in life. Functional decline and age-related pathologies have to be considered in oral health care for this vulnerable population. Retaining and restoring teeth and oral function in elders is important. Tooth loss significantly impairs masticatory performance, which cannot be fully restored by prosthodontic means. Hence an unconscious change in food intake occurs, often involving malnutrition and withdrawal from common meals...

Continued ageing of the global population is expected to pose significant challenges to maintaining optimum lifelong health in individuals and populations. Oral health is an essential element of general health and quality of life throughout an individual's life course, yet it is often neglected in integrated approaches to general health promotion. Surveillance and monitoring systems are essential for developing oral health policy and strategy at both national and community levels. As major oral diseases, dental caries and periodontal diseases are core indicators for surveillance at every stage of life...

Currently, there are three major groups of dentists who provide orthodontic services to the public: postgraduate trained orthodontists, postgraduate trained pediatric dentists, and general dentists who have taken various orthodontic training courses. All of them can expect to encounter a variety of clinical situations that require a proper understanding of how normal temporomandibular joints (TMJs) function, and also how the masticatory system can develop pain-dysfunction problems; those problems are classified and defined as temporomandibular disorders (TMDs)...

Masticatory myofascial pain is the one of the most common etiologies for nonodontogenic pain, often characterized by the presence of trigger points. Conventional management includes approaches such as jaw exercises, physical therapy, intraoral appliances, medications, and trigger point injections. Peripheral/regional nerve blocks have shown to be effective in managing myogenous pain conditions. The twin block is a nerve block that blocks both the masseteric and the anterior deep temporal nerves. The objective of this case series is to illustrate expeditious and sustained efficacy of the twin block in the management of chronic masticatory myofascial pain...

Rhythmic masticatory muscle activity can be a normal variant of oromotor activity, which can be exaggerated in patients with sleep bruxism. However, few studies have tested the possibility in naturally sleeping animals to study the neurophysiological mechanisms of rhythmic masticatory muscle activity. This study aimed to investigate the similarity of cortical, cardiac and electromyographic manifestations of rhythmic masticatory muscle activity occurring during non-rapid eye movement sleep between guinea pigs and human subjects...
