“…Despite a large catchment zone, majority of the population do not seek adequate dental services provided. Hosung Shin and Han-A Cho [11] conducted a study based on secondary data to assess the Spatial barriers and the bypassing of nearby dental clinics for dental services to calculate the distance patients travel to dental clinics, the rate of bypassing nearby dental clinics and the distance covered when bypassing nearby dental clinics, and explored factors associated with patients' spatial access to dental clinics and found that median distance travelled to a dental clinic was 1.8 km, which is farther for rural (8.4 km) than for urban (1.5 km) patients. It can be assumed that choice of transport option as well as availability of public transport option can be a barrier in seeking regular as well as emergency dental services.…”

Background: Information on dental demographic, dental needs, dental providers and the distance from the closest dental institution is necessary to plan for effective delivery of public oral health services. Geographical catchment area of dental hospitals often plays a major role in distribution of adequate health services .Aim of the study is to assess the geographical distribution of patients attending the institution to define the catchment zones and to investigate the changes in the pattern of geographic distribution of patients. 6000 new patients visiting Coorg institute of Dental Sciences and Hospital in the months of January to December in the calendar year 2018 meeting the inclusion criteria were included in the sample. Demographic details along with their location of residence were recorded. A total of 58,982 new patients visited Coorg institute of dental sciences and hospital in the calendar year of 2018.Highest number of patients were reported in the month of December followed by may indicating that hospital has a fairly large catchment zone covering a distance approximately up to 100kms from which 95 % patients reported overlapping those of private dental clinics.

“…23 These variations make truly defining rurality difficult, especially when considering that a rural area adjacent to a metro or suburban area may have better access to dental services than another area that also meets criteria for rurality. 17 As privately insured individuals are more likely to choose to bypass rural health care for both medical and dental needs, 25,26 a binary measure of rurality may not fully capture the impact of rurality on care outcomes experienced by individuals in more remote rural areas.…”

Objectives: Rurality is associated with reduced dental access and worse oral health outcomes. It is unknown whether there is variation in dental services received by rural adults who visit a dentist. Methods: This was a retrospective analysis of claims data from a large private insurer. All individuals who had at least one dental visit in 2018 were included. Patient demographics, whether or not a patient's ZIP code was rural as defined by the Federal Office of Rural Health Policy, as well as ZIP code demographics were collected. Differences in the frequency of dental services received were evaluated using χ 2 tests. Multilevel logistic regressions were used to evaluate the individual and ZIP code-level correlates of receiving a preventive dental procedure, a tooth extraction, or a denture-related dental procedure. Results: Rates of preventive, oral and maxillofacial surgery, and denture-related procedures were higher among rural adults. Accounting for individual age and gender, and ZIP code average income and dentist density, rural dwellers were more likely to receive a preventive procedure [odds ratio (OR) 1.15, P < 0.0001] or tooth extraction (OR 1.08, P < 0.0001), and less likely to have a denturerelated procedure (OR 0.94, P = 0.015) compared to nonrural dwellers. Female gender was the strongest predictor of receiving a preventive procedure (OR 1.30, P < 0.0001). Conclusions: Even among privately insured individuals with known access to dental care, rurality was associated with significant differences in the frequency of various dental procedures. Rural dental patients may have higher needs for oral surgical procedures, even when they have access to preventive care.

“…Marital status was categorized as married or single [ 22 ]. Educational attainment level was classified into three categories: middle school graduation or lower, high school graduation, and college or higher [ 13 , 22 ]. For income, a square root equivalence scale that considered the household’s total earned income, total asset income, and the number of household members for one year was used [ 36 ].…”

“…For example, low-income children and adolescents have been shown to travel longer distances to receive orthodontic treatment than others [ 11 ]. Users of dental treatment for non-covered services of the National Health Insurance (NHI; hereafter ‘non-NHI-covered’) in South Korea, which includes mostly non-emergency and elective treatments (e.g., implants/orthodontics and dental prostheses) traveled further to receive treatment, bypassing the dental office nearest their residence [ 12 , 13 ].…”

This study analyzed patient preferences using travel time from residence to dental institution when selecting dental care services. We used data from the Korean Health Panel from 2008 to 2017 and analyzed each dental service episode. Since the distribution of travel time was skewed to the left, median travel time was analyzed. The association of travel time with services was analyzed via the population-averaged generalized estimating equation (GEE) with the Poisson family. The median of the average travel time per episode was longer for non-National Health Insurance (NHI)-covered services and shorter for NHI-covered services. The first quintile of low-income subjects traveled the longest for all services and utilized dental care the most. In the GEE analysis, travel time was approximately three times longer for implant treatment and gold inlay/resin fillings and >2 times longer for orthodontic care than for NHI-covered services. Patients residing in rural counties traveled for longer than residents of large cities. Income was statistically significant; however, the coefficient was close to zero. Travel time was related to the type of service and reflected patient preference. This was more prominent for expensive non-NHI-covered services than for NHI-covered services. The findings suggest patients’ subjective preferences for dental clinic selection are expressed as rational deliberation considering each individual’s situation.
