Reasons for tooth extraction in four general dental practices in South Wales

Tooth retention has been one of the main aims of oral care which in turn could have contributed to the social oral health divide. To investigate this issue further, data collected for a group audit was used to study the reasons for tooth extraction for patients attending for routine treatment at four dental practices. The practices served populations in areas with different levels of deprivation in South Wales. In 558 teeth extracted over 417 visits, the reasons for extractions were: caries 59%, periodontal disease 29.1%, pre-prosthetic 1%, wisdom teeth 4.6%, orthodontic 5.5%, trauma 1.2%, patient request 2.4% and 6.2% other reason. The number of extraction visits per day within the group of dental surgeons varied with three practitioners performing more than three extraction visits per day while one practitioner had only 0.51. These reasons did not significantly depend on levels of deprivation. However, significantly more teeth were extracted for caries in the most deprived group in comparison to the least deprived. Therefore, could there be a case for appropriate extractions in the quest for equitable care?

“…Increased travel time to receive specialty care for such illnesses is a potentially reversible determinant of adverse outcomes, and several studies have shown that increased distance between the patient's residence and the closest relevant medical specialist is associated with adverse outcomes (9 -12). Even within a relatively small geographic area, shorter distances to healthcare services and availability of such services at the nearest center were strongly related to increased utilization of healthcare and better outcomes (12)(13)(14)(15)(16)(17)(18)(19)(20). Given that geography is a potentially reversible barrier to accessing healthcare services, careful planning to optimize the placement of future healthcare facilities with the goal of enhancing service and improving healthcare outcomes for remote dwellers is critical.…”

“…The last decade has witnessed increased use of geographic information systems (GIS) analysis for measuring access to health services and facilities, healthcare utilization, and relationships with healthcare outcomes (6,7,9,12,(21)(22)(23)(24). However, the use of GIS techniques to determine the optimal location of a healthcare facility with the goal of optimizing patient access is limited (12,18,20,25).…”

“…However, the use of GIS techniques to determine the optimal location of a healthcare facility with the goal of optimizing patient access is limited (12,18,20,25). Given Canada's vast size and relatively sparse population, GIS techniques have the potential to inform decisions on location of healthcare facilities including planning for clinics to care for people with chronic diseases.…”

SummaryBackground and objectives Travel distance to healthcare facilities affects healthcare access and utilization. Using the example of patients with kidney disease and nephrology services, we investigated the feasibility and utility of using geographic information system (GIS) techniques to identify the ideal location for new clinics to improve care for patients with kidney disease, on the basis of systematically minimizing travel time for remote dwellers.Design, setting, participants, & measurements Using a provincial laboratory database to identify patients with kidney disease and where they lived, we used GIS techniques of buffer and network analysis to determine ideal locations for up to four new nephrology clinics. Service-area polygons for different travel-time intervals were generated and used to determine the best locations for the four new facilities that would minimize the number of patients with kidney disease who were traveling Ͼ2 hours. ResultsWe studied 31,452 adults with living in Alberta, Canada. Adding the four new facilities would increase the number of patients living Ͻ30 minutes from a clinic by 2.2% and reduce the number living Ͼ120 minutes away by 72.5%. Different two-and three-clinic scenarios reduced the number of people living Ͼ120 minutes away by as much as 65% or as little as 32%, emphasizing the importance of systematic evaluation.Conclusions GIS techniques are an attractive alternative to the current practice of arbitrarily locating new facilities on the basis of perceptions about patient demand. Optimal location of new clinical services to minimize travel time might facilitate better patient care.

“…Today's health planners aim at developing health policy and services that address geographic and social inequalities in health, and therefore should benefit from evidence-based approaches that can be used to investigate spatial aspects of health policy and practice, and evaluate geographic equity (or inequity) in health service provision [15]. …”

Background: 'Traffic light' (red-yellow-green) maps are potentially powerful tools for 'at a glance' problem detection, for optimising resource allocation/reallocation, setting priorities, and targeting interventions to areas most in need. The maps can be also used for administrative area comparisons and performance monitoring over time. Interactive Web versions of the maps can be generated with many handy features to further empower organisations and decision makers. Methodological issues to consider when creating 'traffic light' maps include hue thresholding, data timeliness and stability of administrative boundaries.
