Common pathological conditions in remains
-
- results from bacterial fermentation of dietary carbohydrates leading to tooth decay (cavities)
- involves inflammation and infection of the gums and supporting structures of the teeth (periodontitis)
- form as a result of untreated dental caries or trauma leading to pus accumulation
- manifests as linear or pitted defects in tooth enamel due to disrupted amelogenesis during childhood (malnutrition, illness)
-
- caused by prolonged vitamin C deficiency leading to weakened collagen production and hemorrhaging (subperiosteal new bone formation)
- results from vitamin D deficiency during childhood causing softening and deformation of bones (bowed legs, flared metaphyses)
- characterized by decreased bone density and increased fracture risk due to hormonal changes, aging, or dietary deficiencies (calcium, vitamin D)
- Infectious diseases
- involves bacterial or fungal infection of the bone causing inflammation, pus formation, and necrosis (sequestrum, involucrum)
- can spread to the skeleton, particularly the spine (Pott's disease), causing destruction and collapse of vertebral bodies
- affects the hands, feet, and facial bones causing erosive lesions and resorption of bone (penciling of phalanges, rhinomaxillary syndrome)
- , including syphilis, causes distinctive skeletal lesions (caries sicca, saber shin, Charcot joint)
-
- can occur due to accidents, interpersonal violence, or occupational stresses (parry fractures, rib fractures)
