# 牙本质嗜碱性颗粒(Dentin Basophilic Granules) - 器官 / 系统:牙齿 / 消化系统(tooth / alimentary-system) - NTP 数据编号:ntp-0256 - 规范 URL:https://www.labsmart.cn/ntp/tooth-dentin-basophilic-granules.html - 中文图谱总页锚点:https://www.labsmart.cn/ntp-atlas.html#tooth-dentin-basophilic-granules - 原始出处:https://ntp.niehs.nih.gov/atlas/nnl/alimentary-system/tooth/Dentin-BasophilicGranules - 授权:美国联邦政府作品,公有领域;引用请标注 NTP Nonneoplastic Lesion Atlas - 适用说明:仅供科研使用,不用于临床诊断 ## 一句话结论 牙本质中的嗜碱性颗粒(Figure 1、Figure 2)在NTP研究中罕见。它们是小而圆的嗜碱性球状物,在牙本质层内呈线性排列。 ## 病变描述(中文) 牙本质中的嗜碱性颗粒(Figure 1、Figure 2)在NTP研究中罕见。它们是小而圆的嗜碱性球状物,在牙本质层内呈线性排列。在暴露于氟化钠2年的F344大鼠的predentin和dentin中曾见到此类颗粒。据报道,类似的沉积物代表牙齿/骨骼标本脱钙过程中形成的氟化钙结晶。 ## 诊断与分级建议(NTP 共识,中文) 嗜碱性颗粒一旦出现即应诊断并分级。 ## 英文原文 · Comment Basophilic granules in the dentin ( Figure 1 and Figure 2 ) are rarely seen in the NTP studies. They are small, round, basophilic globules that occur in a linear pattern within the dentin layer. They have been seen in the predentin and dentin in F344 rats exposed to sodium fluoride for 2 years. Similar deposits are reported to represent calcium fluoride crystal formation that occurs during decalcification of tooth/bone specimens. ## 英文原文 · Recommendation Basophilic granules should be diagnosed and graded whenever present. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0199.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0195.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
