Using data available on dentists for 1972, 1982 and 1992 and on dental therapists for 1992 the geographical distribution of dental operators (dentists/dental therapists) in South Africa was determined and the dental operator to population ratios were calculated. Over a period of 20 years the number of dentists in South Africa has increased by 135,6 per cent while the total population of the area has increased by 59,8 per cent. The lowest operator to population ratio was 1:4517 found in the PWV region, and the highest ratio was 1:48730, recorded in the Northern Transvaal. The greatest decrease in dental operator to population ratios occurred in Natal and Transvaal. The study shows that there is an imbalance in the geographic distribution of dental operators favouring large urban areas.
利用1972年、1982年和1992年有关牙医的数据以及1992年有关牙科治疗师的数据，确定了南非牙科从业者（牙医/牙科治疗师）的地理分布，并计算了牙科从业者与人口的比例。在20年的时间里，南非的牙医数量增加了135.6%，而该地区的总人口增加了59.8%。最低的从业者与人口比例是在比勒陀利亚-韦伦加-瓦尔三角地区发现的1:4517，最高比例是在北德兰士瓦记录的1:48730。牙科从业者与人口比例下降最大的是纳塔尔和德兰士瓦。该研究表明，牙科从业者的地理分布不均衡，有利于大城市地区。
