【摘要】：目的:比較中國南寧和老撾萬象人上頜第一恒磨牙的解剖形態(tài)，為牙髓病治療提供臨床參考依據。 方法：搜集來自中國南寧和老撾萬象地區(qū)人上頜第一恒磨牙各22顆。通過電子數顯卡尺測量牙體外形，手術顯微鏡觀察髓室底溝形態(tài)、透明牙技術了解近中頰根根尖孔數目、位置類型以及根管形態(tài)。采用SPSS19.0軟件對以上各組數據進行統(tǒng)計學分析。 結果：中國南寧和老撾萬象人上頜第一恒磨牙的平均牙長分別為18.73mm、18.40mm，牙冠長度分別為7.21mm、6.40mm,根長分別為11.52mm、12.00mm，。南寧人牙冠比萬象人長，，差異有統(tǒng)計學意義(P0.05),根長和牙長均無統(tǒng)計學差異（P0.05）。兩組人群上頜第一恒磨牙的髓室底溝形態(tài)均以均以“7”型和“Y”為主，差異不存在統(tǒng)計學意義(P0.05)。近中頰根根尖2個以上根尖孔的發(fā)生率為南寧人77%，萬象人59%(P0.05)，近中頰根根尖孔位于根尖區(qū)的比例分別為44%和43%（P0.05)。南寧人的近中頰根的根管形態(tài)以I型、IV型和V型為主，分別占32%，22.7%和18%，萬象人則以I型、II型、IV型為主，分別占27%、32%、27%，兩組居民的近頰根根管形態(tài)存在統(tǒng)計學差異（P0.05）。 結論：1、南寧和萬象人的上頜第一恒磨牙髓室底溝以“Y”型和“7”型為主。2、南寧人的上頜第一恒磨牙近頰根尖孔數目更多。3、兩地區(qū)人上頜第一恒磨牙近頰根尖孔主要位于非根尖區(qū)。4、兩地區(qū)人上頜第一恒磨牙近頰根雙根管存在率高。
[Abstract]:Objective: to compare the anatomical morphology of maxillary first molar in Nanning and Vientiane, China, and to provide clinical reference for the treatment of pulp disease. Methods: a total of 22 maxillary first permanent molars were collected from Nanning and Vientiane regions of China. The shape of teeth was measured by electronic digital caliper, the morphology of pulp floor sulcus was observed by operation microscope, and the number of apical foramen of proximal buccal root was determined by transparent tooth technique. The location type and root canal morphology were analyzed statistically by SPSS19.0 software. Results: the average tooth length, crown length and root length of maxillary first permanent molar in Nanning and Laotian were 18.73 mm and 18.40 mm, 7.21 mm and 6.40 mm, respectively, and the root length were 11.52 mm and 12.00 mm, respectively. The tooth crown of Nanning was longer than that of Vientiane. There was no significant difference in root length and tooth length between the two groups. The incidence of more than 2 apical foramen in the proximal buccal root tip was 77 in Nanning people, P0.05 in Vientiane, 44% in the apical area of the proximal buccal root root, and 43 in the apical region of the proximal buccal root. The root canal shape of the proximal buccal root of Nanning people was similar to that of the proximal buccal root in Nanning. I type IV and V type are dominant. The proportion of 32% and 18% was 22. 7% and 18%, respectively. In Vientiane, type I, type II and type IV were dominant, accounting for 2732 and 27, respectively. There was a statistical difference between the two groups in the morphology of the proximal buccal root canal (P0.05). ConclusionThe root sulcus of maxillary first permanent grinding pulp in Nanning and Vientiane is mainly "Y" and "7". The number of proximal foramen of maxillary first molar is more. 3 in Nanning and Vientiane. The main foramen of maxillary first permanent molar is mesiobuccal apical foramen in both regions. In the non-apical region of. 4, the presence of double canals in the buccal root of the first maxillary permanent molar was high in both regions.
