The purpose of this study was to discriminate clinically and radiographically among the three groups of dentigerous cysts studied. First, Group I , involved area of dentigerous cyst was successive permanent tooth area beneath deciduous tooth. Second, Group II , involved permanent molar area, and the last, Group 111, in¡þvolved maxillary anterior supernumerary tooth area.
The author observed and compared the clinico-radiographic features of 49 cases of Group I , 36 cases of Group 1, and 15 cases of Group III of dentigerous cyst and this observation and comparison had been done by based on the charts and panoramic films.
The obtained results were as follows
1. The cases of Group I were 29 cases and, those of Group 1I were 36 and those of Group I were 15.
2. The incidence of dentigerous cyst is high in first decade. In Group I , before first decade and early first
decade was 87.8%, in Group 11 and Group 111, was discovered more lately.
3. The frequency of dentigerous cyst is 2.5 times higher in male than in female.
4. The sequence of chief complaint was swelling(50%), routine examination(32%), and pain(9%).
5. When considering the type of the cyst, lateral type is many most in Group I (71.4%) and central type is
many most in Group 1 (94.4%) and Group 111(100%) .
6. The most size of dentigerous cyst was 2 crown size. in Group I , 1 crown size in Group 11 , above of 4 crown size in Group 1.
7. Almost involved teeth showed displacement and some tooth of displaced teeth showed delayed root devel¡þopment and dilaceration of root.
8. The most many response of alveolar bone was buccal bone expansion in Group I (67.3%), no bone expan¡þsion in Group 11(66.7%) and palatal bone expansion in Group 111(60.0%).
9. The percentage of involved teeth were as follows : The mandibular third molar was 31% and many most. The mandibular second premolar was 30%. Mesiodens of maxillary anterior area was 15%. The maxillary canine was 8%. The mandibular first premolar was 5%.
10. In the Group I , causes suggesting of dentigeous cyst are pulpotomized deciduous tooth(59.2%), severe dental caries of deciduous tooth, untreated traumatic history on the deciduous tooth etc.
11. The treatment method of dentigerous was marsupialization in 61.2% of cases of Group I and that was enucleation in 61.1% of cases of Group II and in 80.0% of cases of Group III.
