Different distributions of fluorotic dental enamel within the dentition have been described in the literature. This report describes two patterns of intraoral distribution. In nine Tanzanian low fluorosis communities with a prevalence of pitting fluorosis of less than 2% and in five moderate fluorosis communities with a prevalence of pitting fluorosis of 16-59%, incisors and first molars were the least affected teeth. In four high fluorosis communities with a prevalence of pitting fluorosis of 86-97%, maxillary incisors exhibited lower Thylstrup-Fejerskov Index values than the maxillary canines, premolars and molars. The mandibular teeth exhibited increasing Thylstrup-Fejerskov Index values from the anterior to the posterior region. The curves presenting the intraoral distribution of the severity of dental fluorosis corresponded with the curve presenting the completion time of primary enamel formation of the various tooth types, with the exception of the first molars in high fluorosis communities. The similarity of the curves suggests that the later in life enamel is completed, the higher is the severity of dental fluorosis. This relation seems to be explained by the prevailing feeding and dietary habits, which result in minimal intake of fluoride in the first 18 months of life during breastfeeding, followed by increasing fluoride ingestion in the following years through consumption of tea, seafish and F-containing magadi salt.
文献中已描述了牙列中氟斑牙釉质的不同分布情况。本报告描述了两种口腔内分布模式。在9个坦桑尼亚低氟社区（斑点状氟斑牙患病率低于2%）和5个中度氟社区（斑点状氟斑牙患病率为16%-59%）中，门牙和第一磨牙是受影响最小的牙齿。在4个高氟社区（斑点状氟斑牙患病率为86%-97%）中，上颌门牙的蒂尔斯楚普-费耶斯科夫指数值低于上颌尖牙、前磨牙和磨牙。下颌牙齿从前部到后部区域的蒂尔斯楚普-费耶斯科夫指数值逐渐增加。呈现氟斑牙严重程度口腔内分布的曲线与呈现各种牙型釉质初步形成完成时间的曲线相符，但高氟社区的第一磨牙除外。曲线的相似性表明，釉质形成完成得越晚，氟斑牙的严重程度越高。这种关系似乎可以通过普遍的喂养和饮食习惯来解释，即在生命的前18个月母乳喂养期间氟摄入量最低，随后在接下来的几年中通过饮用茶、食用海鱼和含氟马加迪盐导致氟摄入量增加。
