In the past, most of the literatures relating to periodontitis are centered n measuring clinic periodontal periodontal probing depth and clinic periodontal attachment loss of the various periodontal diseases. The researches on the level and the rate of alveolar bone fracture, as well as the tooth loss rate of the aggressive periodontitis on natives are limited. As there is a trend that the natives who suffer from peiodontitis are gradually getting younger, the purpose of this research is aimed on the measurement and estimation of the X-ray cumulative alveolar bone loss and the tooth loss rate of the aggressive periodontitis (AGP) which were newly classified from AAP in 1999. Furthermore, from this study, the differences on the cumulative radiographic alveolar bone loss (CRABL), yearly radiographic alveolar bone loss (YRABL) and tooth loss rate (TLR) between AGP and other patients can also be compared and revealed.
The samples of this research were taken from the patients who received treatments in Kaohsiung Medical University. Sixty AGE patients and ten health adult patients were taken as samples for the study. The full mouth X-ray film and basic data of the samples were collected for calculating the distance between CEJ to the top of alveolar bone from the mesial side and distal side of the tooth and TLR respectively by DEC.
The results of this research are listed below:
Age (P<0.0001), sex (P<0.0235), Disease Classification (P<0.0001), and Tooth Loss Rate (P<0.0001) have remarkable correction with CRABL %.Only the factors of Age and Disease Classification have notable links with YRABL%.Age (P<0.0023), and Disease Classification (P=0.0218) also have distinguished correlations with tooth loss rate. As the age increases, the tooth loss rate increases. The tooth loss rate of the AGP group is twenty times more than the healthy adult group is about five times more than the health adult group.CRABL % increases along with the age. The CRABL % of the AGP group is more critical than LAGP group and the male group is also more serious than the female group.YRABL % decreases along with the age. The YRABL % of AGP group and LAGP group is about 2~3 times than the healthy adult group.The highest tooth loss rate is the molar, followed by the second molar, premolar, incisor and then the canine.The highest average of CRABL % and YRABL % is the Aggressive Periodontitis Group (59.85%;2.24%), followed by the Localized Aggressive Periodontitis Group (41.3%;1.97%), and finally the Healthy Adult Group (9.96%;0.08%).
