Dental abscess: A potential cause of death and morbidity.

BACKGROUND: Dental abscess as an end stage of dental disease is common in the community, and patients with dental abscesses are likely to seek care from their primary health provider. Once the infection has spread beyond the confines of the jaws, there is an increasing risk of airway obstruction and septicaemia. If treated with antibiotics alone, the infection will not resolve and will become progressively worse. OBJECTIVE: This article reviews the pathophysiology, demographics and management of severe odontogenic infections. It includes evidence-based studies of a large number of cases treated at a single tertiary hospital. DISCUSSION: Prompt assessment and referral to a tertiary hospital is required for cases at risk of airway compromise. The morbidity and mortality of cases is presented in this article, with discussion of risk factors and the financial burden on the health system.

Post mortem survey of dental disorders in 349 donkeys from an aged population (2005-2006). Part 2: epidemiological studies.

REASON FOR PERFORMING STUDY: Dental disorders have recently been recognised as having major clinical and welfare implications in donkeys. However, no investigation appears to have examined the association of dental disorders with managemental factors and any intercurrent illness. OBJECTIVES: To determine the association of dental disorders observed in a post mortem study with age group, body condition score, time since last dental treatment, feeding and the illness that necessitated euthanasia or caused death. METHODS: A prospective study documented the type and prevalence of dental disorders in 349 mainly aged donkeys (median estimated age of 31 years) that were subjected to euthanasia over an 18 month period in 2005'Aì2006. The estimated age, body condition score, supplemental feed status, time since last dental treatment and nature of the intercurrent disease that necessitated euthanasia or caused death were also recorded. Multivariable analysis was performed to examine associations of these factors with specific dental disorders and between specific dental disorders. RESULTS: There was a high prevalence (93.4%) of significant dental disease. Age group was significantly associated with the presence of dental disorders and an older age range was a high risk factor for the presence of cheek teeth (CT) diastemata. There was a significant association between the presence of CT diastemata and the concurrent presence of displaced, missing and worn CT. There was also a significant association between the presence of diastemata and colic. CONCLUSIONS AND POTENTIAL RELEVANCE: Aged donkeys have a high prevalence of dental disorders especially of CT diastemata. Dental disorders and, in particular, the presence of CT diastemata were significantly associated with colic. Routine, prophylactic dental treatments should be performed, especially in aged donkeys.
