Eruption cysts: A series of two cases
An 8 year old male child along with his parents reported to the Department of Pedodontics with the chief complaint of bluish black swelling on the gums in the front region of the upper jaw []. Parents of the child were fearful; assuming the lesions to be malignant tumor. History of the case revealed that 61 was extracted 1 year back due to caries. The lesions started appearing 2 weeks back as translucent swellings over normal mucosa and it slowly increased to its present size. The color of the lesions also slowly changed from its normal red mucosa to the present bluish black color 1 week back. No fluid discharge or any other associated symptoms were associated. The general physical examination of the child showed no abnormalities. There was no history of any acute infection, trauma, and drug or food allergy in the recent past. Examination of the oral cavity revealed that the child was in the mixed dentition stage. All the permanent 1st molars had completely erupted and all incisors except 21 were in various stages of eruption. Carious lesions were present with respect to 52, 62 and 73. Soft tissue examination did not show any abnormalities except, the presence of gingival swelling with respect to 21. Clinically the gingival lesions appeared as bluish-black, circumscribed, fluctuant swellings on the buccal gingiva over the site of un-erupted 21. Swelling measured approximately 1.5 × 2 cm and was very soft and fluctuant. The overlying mucosa was smooth and no ulceration was present. X-rays of the lesions confirmed the presence of 21 in the stage of eruption and there were no signs of bone involvement or any radiolucency surrounding this tooth. It was clinically and radio graphically diagnosed as eruption cyst with 21.\nThe clinical condition was explained to the parents and they were advised to observe the swellings for another 2 weeks as it may rupture on its own and may not need any surgical intervention. Patient reported after 15 days. The swelling was still present and dull aching pain was present on mastication. The surgical procedure was explained to the parents and consent was obtained for the same. A blood investigation was carried out before the procedure. The treatment included incising the eruption cyst with BP blade and draining the contents of the cyst. A window was cut leading to the exposure of 21. Post operative instructions were given [].\nThe patient was reviewed after one week and a normal eruption pattern was observed.
