usually directed buccolingually. The fracture may involve one proximal surface (buccal or lingual) or both buccal and lingual proximal surfaces. The fracture is located in the root portion of the tooth only, and may extend coronally toward the cervical periodontal...
The extruded tooth was repositioned and splinted with a heavy wire and adhesive resin, after which a resorbable collagen tissue was placed to cover the buccal region. Subsequent to the injury, swelling was observed and the patient complained of pressure pain in the periapical region of the ...

dentin, and to understand the role of individual structural elements in the fracture of dentin.ResultsAbsent in peritubular dentin, root dentin is insensitive to cracks and exhibits higher fracture resistance than coronal dentin that has a typical brittle fracture behavior along the peritubular dentin....
However, there are ways you can make sure you don’t suffer from vertical root fractures in the first place. Here’s all you need to know: To save a tooth from this type of crack, it’s key not to take it through a root canal treatment. Instead, you should regularly visit your den...
The purpose of this study was to compare endodontically versus nonendodontically treated teeth with respect to clinical features, including patient age and gender and tooth types of vertical root fractures.A total of 315 consecutive cases of vertical root fracture occurring in 274 Chinese patients duri...

More closely related mammals also vary in tooth form depending on diet, albeit in subtler ways; such is the case with primates (Figure 2). Folivorous langurs have cheek teeth with taller cusps and longer shearing blades than do hard-object-feeding mangabeys. Frugivores, and those with bro...
摘要: Objectives The aim of this study was to investigate the prevalence, by gender, of vertical root fracture (VRF) as the main reason for the extraction of permanent teeth in dental clinics in Tokyo.关键词: Vertical root fracture Reasons for tooth extraction Permanent teeth Prevalence ...
