Persistent Toothache Despite Multiple Dental-related Treatments: How Could this Be?

Patients with recurrent or persistent dentoalveolar pain usually believe that endodontic treatment or extracting a tooth will alleviate it, and most cannot conceive that the pain might not be tooth related. Understanding that dental procedures of any kind will be ineffective when a tooth-related pathology is ruled out and that a nonodontogenic etiology best explains the "toothache" pain goes against their beliefs. In this article, we present an overview of basic concepts to help manage such cases by briefly outlining possible causes of nonodontogenic pain as well as diagnostic pitfalls that may lead to questionable treatments.

Relationship Between Disease Characteristics and Oral Radiologic Findings in Systemic Sclerosis: Results From a Canadian Oral Health Study.

Objective: Systemic sclerosis (SSc; scleroderma) is associated with a wide periodontal ligament (PDL) and mandibular erosions. We investigated the clinical correlates of SSc with these radiologic abnormalities.

Methods: Subjects from the Canadian Scleroderma Research Group cohort underwent detailed radiologic examinations.

The Canadian Systemic Sclerosis Oral Health Study IV: oral radiographic manifestations in systemic sclerosis compared with the general population.

Objective: The aim of this study was to compare oral radiologic abnormalities associated with systemic sclerosis (SSc) against abnormalities in the general population.

Study Design: Patients with SSc and healthy controls were enrolled in a multi-site cross-sectional study. Included in the radiology examination were a panoramic radiograph, four bitewings, and an anterior mandibular periapical radiograph.

Relationship between disease characteristics and orofacial manifestations in systemic sclerosis: Canadian Systemic Sclerosis Oral Health Study III.

Objective: Systemic sclerosis (SSc; scleroderma) is associated with decreased saliva production and interincisal distance, more missing teeth, and periodontal disease. We undertook this study to determine the clinical correlates of SSc with these oral abnormalities.

Methods: Subjects were recruited from the Canadian Scleroderma Research Group cohort.

The Canadian systemic sclerosis oral health study II: the relationship between oral and global health-related quality of life in systemic sclerosis.

Objective: Both oral and global health-related quality of life (HRQoL) are markedly impaired in SSc. In this study we aimed to determine the degree of association between oral HRQoL and global HRQoL in SSc.

Methods: Subjects were recruited from the Canadian Scleroderma Research Group registry.
