[Retracted] Dosimetric Comparison between Volumetric Modulated Arc Therapy (VMAT) and Intensity-Modulated Radiotherapy (IMRT) for Dental Structures of Head and Neck Cancer Patients

Table 3

Radiation doses received by maxillary and mandibular teeth using IMRT.

		Nasopharynx	Oral cavity	Oropharynx	Larynx
Maxillary teeth	Mean of average	37.56 ± 3.46 ^aA	24.60 ± 11.41 ^bA	23.22 ± 12.3 ^bA	22.21 ± 8.46 ^bA
	Mean of maximum	67.00 ± 6.72 ^aA	45.66 ± 3.48 ^bA	46.29 ± 16.8 ^bA	38.57 ± 14.50 ^bA
Mandibular teeth	Mean of average	31.49 ± 3.93 ^aB	49.76(7.34)^bB	35.31 ± 11.45 ^aB	27.95 ± 6.05 ^aB
	Mean of maximum	54.77 ± 6.65 ^aB	63.87 ± 9.17 ^bB	61.53 ± 9.28 ^bB	42.34(10.70)^cA

Different lowercase letters in the rows represent significant differences () (one-way ANOVA or the Kruskal-Wallis test). In each row, we compared the radiation doses of maxillary and mandibular at different tumor locations. Different capital letters in the columns represent significant differences () (independent-samples t-test or Mann-Whitney test). In each column, we compared the average doses (maximum dose) of the upper and lower teeth of the same tumor locations.
