Analysis of Dental Tissues Density in Healthy Children Based on Radiological Data
Background:
Background:The information about the Hounsfield range values for healthy teeth tissues could become an additional tool in assessing dental health and could be used, among other data, for subsequent machine learning.
Objective:
Objective: The purpose of our study was to determine dental tissues density values in Hounsfield units.
Methods:
Methods:The total sample included 36 healthy children (21 girls, 15 boys) with an age range from 10 to 11 years at the time of the study. The analysis of 320 teeth tissue density was carried out.Data were expressed as mean±standard deviation. The significance was determined using Student's t-test. The statistical significance was set at P<.05.This study is not a randomized controlled trial and is therefore not registered in the ClinicalTrials.gov.
Results:
Results:The analysis of 320 teeth tissue density was carried out: 72 - 1st permanent molars, 72 - permanent central incisors, 27 - 2nd primary molars, 40 - tooth germ of 2nd premolars, 37 - 2nd premolars, 9 - 2nd permanent molars, 63 - tooth germ of 2nd permanent molars. Analysis of the data showed that tissues of healthy teeth in children have different density ranges: enamel - 2954.69±223.77HU-2071.00±222.86HU, dentin - 1899.23±145.94HU-1323.10±201.67HU, pulp - 420.29±196.47HU-183.63±97.59HU. The tissues (enamel, dentin) of permanent central incisors in the mandible and maxilla had the highest mean density value. No gender differences concerning the density of dental tissues were reliably identified.
Conclusions:
Conclusions:Evaluation of Hounsfield values for dental tissues can be used as an objective method for assessing their density. If determined density values of enamel, dentin and pulp of the tooth do not correspond to the range of values for healthy tooth tissues, it may indicate a pathology.
