Now the question arises whether it is non- shedding primary teeth that led to impaction
of succedaneous teeth or is it failure of eruption of succedaneous teeth or lack of eruptive forces that led to retainment of primary teeth, is open to debate.
Impacted maxillary canine is considered 2nd most impaction
after third molars.9,10 MIC is rare clinical situation in orthodontics and is reported to be in the range of less than twice to 20 times less than maxillary canine impaction
.11-13 The etiology of MIC include both genetic and environment factors.12 MIC can labially or lingually displaced and some times transmigrated.
Stress associated with introduction into a new environment, the absence of pasture or grass in the paddocks where the geese were introduced, inadequate availability of food, and clearly visible sand in the paddocks may have been predisposing factors for the development of sand ingestion and impaction
in this goose.
Otherwise these should be avoided, as impaction
to bezoar (concretions) formation will result, especially in the incontinent patient.
The maxillary canine is the last tooth to erupt with a primary predecessor so it is susceptible to environmental influences that may affect its eruption leading to its impaction
In the age group of 31-35 years, the results from Graphs 5 and 6 show the horizontal and distoangular third molar impactions
(67%) which more frequently cause an effect on adjacent second molar which results in decay while the vertical third molar impactions
(33%) show the least effect on adjacent second molar.
Another study by Ahmad et al15 concluded that the prevalence of impacted teeth was high, and there was a predominant for impaction
of the mandibular third molars in this study of Al Ahsa Saudi population.
Moreover, the visibility of fish bones varies with respect to different fish species, its anatomic location of impaction
and orientation within the upper aerodigestive tract.7 Plain radiograph has poor sensitivity and specificity.
(18) Ultrasound and positive contrast fluoroscopy can help further characterize gastrointestinal abnormalities and differentiate between gastric impactions
with partial or complete obstruction.
An immediate upper intestinoscopy was undertaken in order to exclude esophageal impaction
and two button batteries were removed from the stomach of the patient.
The following are recommendations for the management of ingested for foreign bodies and food impactions
A foreign body impaction
(FBI) in the esophagus can be a serious condition with high mortality rate among children and adults.
