作者收集佛山市口腔医院1990～1993年尖周病患者的104张X线牙片.男67例,女37例,年龄18～56岁.全部病例均经两单位认定为尖周病,并经常规X线片证实.尖周病多由感染引起,龋病为最常见的病因(包括残冠残根),本组中龋病为66例,占63.4%,畸形牙9例,占8.65%;创伤合12例,占11.54%;牙折10例,占9.61%;髓室侧穿3例,占2.89%;桥基牙2例,占1.92%;髓腔内吸收与乳牙滞留各1例,各占0.96%.尖周病的X线片示尖周稀疏区多见于根尖部,在本组为79例.占70.54%;在根侧部20例,占17.86%;根分叉部13例,占16.6%.一般为圆形或椭圆形区,本组共92例,占88.46%,边缘清晰,无致密线条围绕.本组不规则形稀疏区12例,占11.54%.一般稀疏区范围较小,直经多<1cm,本组共有102例,另2例≥1cm.究竟是根尖肉芽肿、根尖脓肿还是根尖囊肿?精确诊断要依靠组织学检查.故未给本组104张X线牙片加以诊断性细分.
The author collected 104 oral radiographs of patients with periapical disease in Foshan Stomatological Hospital from 1990 to 1993. There were 67 males and 37 females aged from 18 to 56. All the cases were confirmed as spina bifida by two units, Conventional X-ray confirmed. Vertebral disease and more caused by infection, caries as the most common cause (including residual crown), caries in this group was 66 cases, accounting for 63.4%, deformity teeth in 9 cases, accounting for 8.65% ; Trauma in 12 cases, accounting for 11.54%; 10 cases of fracture, accounting for 9.61%; 3 cases of medullary lateral wear, accounting for 2.89%; abutment abutment in 2 cases, accounting for 1.92%; intramedullary absorption and deciduous teeth retention in 1 case , Each accounting for 0.96% .Near sharp lesions on the X-ray showed sparse apical week more common in the apical part, in this group of 79 cases .Of 70.54%; in the lateral side of the 20 cases, accounting for 17.86%; root bifurcation 13 cases, accounting for 16.6%, generally round or oval area, a total of 92 cases of this group, accounting for 88.46%, clear edge, no dense lines around the group of irregular sparse area in 12 cases, accounting for 11.54% District smaller, straight more than 1cm, a total of 102 cases in this group, and the other 2 cases ≥ 1cm. Whether it is apical granuloma, apical or apical aponeurosis? The exact diagnosis depends on histological examination. Group of 104 X-ray teeth to be diagnostic subdivision.
