Horizontal/oblique root fractures in the palatal root of maxillary molars with associated periodontal destruction: case reports

Abstract

Horizontal/oblique root fracture of the palatal root in molars is rare. A combination of periodontal and root canal treatment and palatal root amputation may allow short-term preservation of functional teeth.

Horizontal root fractures in posterior teeth without dental trauma: tooth/root distribution and clinical characteristics

“…, Lin et al . ). Whether the age‐related structural change or long‐term usage of teeth resulted in HRF in posterior teeth is unclear and needs to be investigated in further studies.…”

“…Similarly, widespread tooth wear was also noted in case reports of HRF (Lin et al . , Wang et al . ) and in this study.…”

“…, Lin et al . ). The fracture patterns are classified into several types: vertical, horizontal and surface root fracture (cementodentinal tears; Rivera & Walton , Lin et al .…”

“…Root fractures are commonly observed in teeth with prior endodontic treatment or a history of dental trauma (Chan et al 1999, Lin et al 2008. The fracture patterns are classified into several types: vertical, horizontal and surface root fracture (cementodentinal tears; Rivera & Walton 2002.…”

Diagnostic value of cone beam computed tomography for recognition of oblique root fractures: An in vitro study

“…Another cause of oblique root fractures is repeated excessive pressure during the mastication of hard food, 5,6 which is usually observed in subjects above the age of 40 years and mostly affects lateral teeth, resulting from age-related changes in tooth elasticity and the presence of numerous and large fillings. 7 There is a lack of data on the prevalence of oblique root fractures, because they are frequently recognized as horizontal ones. The diagnosis of tooth root fractures is predominantly based on radiological imaging, which is often unreliable in relation to oblique fractures.…”
