Correlated characteristics of the jaws: Association between torus mandibularis and marginal alveolar bone height

Abstract

The factor marginal alveolar bone height and torus mandibularis (TM) were studied in 2 groups of dentate patients more than 20 years of age, altogether 571 individuals. Subgroups possessing TM had the higher prevalence of unimpaired bone height as compared with those without the trait (P less than 0.001). Different environmental factors considered, such as food habits, exposure to infection, oral hygiene habits, bruxism, access to professional dental care, and habits as to seeking dental treatment, did not seem to account for or to have any influence on the observed phenotypic correlation between TM and more favorable bone height. It was therefore suggested that TM and marginal bone seem to be influenced by common pleiotropic genes. It is hypothesized that future disclosure of the loci that regulate the capacity to develop TM at the same time may throw some light on the genetic contribution and mechanisms that tend to make the marginal alveolar bone more resistant to destructive agents.

Current status of the torus palatinus and torus mandibularis

“…(5,12) Thus, Sirirungrojying et al (5) determined that TM can be used to indicate the risk of appearance of temporomandibular disorders. As possible causes, other authors mention eating habits, (4,5,7) states of vitamin deficiency or supplements rich in calcium (13), and also diet (4,(16)(17)(18)(19). In the studies conducted by Eggen et al (18) and Al-Bayaty et al (4), they associate the consumption of fish with the presence of tori, because fish contains Ω3 unsaturated fatty acids and vitamin D, encourages bone growth.…”

Oral Tori Are Associated With Local Mechanical and Systemic Factors: A Case-Control Study

“…The exact etiology of oral tori has eluded investigators for decades, but it is believed that the trait (TP and/or TM) is expressed when a certain threshold of genetic and local environmental factors is surpassed. 4,5,8,10,[12][13][14][15][16][17][18][19][20][21] Historically, studies on the etiology of these bony lesions have focused on genetic and environmental influences, but have neglected to investigate the broad scope of interdependent factors involved in bone metabolism. The purpose of this investigation was to undertake a broader assessment of potential environmental influences and, in doing so, address the following question: in subjects with oral tori, are there associations with various dental factors, medications, and medical conditions compared with control subjects?…”

Periodontal disease in the Mycenean (1450–1150 BC) population of Aghia Triada, W. Peloponnese, Greece

“…Other researchers also mention that hard food decrease and soft diet increase the incidence of periodontitis (Shaw 1962, Mitsis, 1981. Dietary, genetic and cultural differences may be the reason of the low or the high frequency of the disease in archaeological material or lived people from geographically distant countries (Marshall-Day, 1949; Mitsis & Taramidis 1995; Clarke et al, 1986;Eggen 1992, ).…”
