Treatment outcome of the teeth with cemental tears.

Introduction: A cemental tear is a special type of surface root fracture noted in combination with periodontal and/or periapical bony destruction. We hypothesized that clinical characteristics and treatment techniques may affect the prognosis of teeth with cemental tears.

Methods: Treatment outcome for the teeth with a cemental tear was assessed in a multicenter cemental tear study project.

Cemental tear: clinical characteristics and its predisposing factors.

Introduction: Cemental tears often show characteristics mimicking a periapical or periodontal lesion. This leads to difficulty in the early diagnosis of cemental tears.

Methods: In this multicenter study, 71 teeth with cemental tears being confirmed by direct inspection or histological examination were included.

Cemental tear on a mandibular second molar: a case report.

A cemental tear is a special kind of root fracture that may cause rapid and localized periodontal destruction. Most cemental tears have been reported on bicuspids and incisors. Here we present a case of cemental tears on both the right mandibular first and second molars.

Periodontal disease activity measured by the benzoyl-DL-arginine-naphthylamide test is associated with preterm births.

Background: Infection is a risk factor for preterm birth. This study was conducted in the field and addressed the link between periodontal pathogens measured with the benzoyl-DL-arginine-naphthylamide (BANA) test and preterm birth.

Methods: This prospective study was performed in Changhua, Taiwan.
