Radiographic Study of Developmental Alteration in Tooth Number among Children in IIUM Dental Clinic
Abstract: The aim of this
research was to determine the prevalence, distribution and association of
developmental alteration in tooth number with gender, location, and presence of
delayed eruption of tooth among children who attended to Student's polyclinic
of IIUM Kuantan, Malaysia. Methods: A cross sectional study on total 727 Orthopanthomograms
(OPGs) of 3-17 years old children from April 2009 to July 2012. OPGs with
presence of alteration number were scrutinized to find out the prevalence,
distribution and association. The data was analyzed comparing gender, location
and presence of delayed eruption and tested using Chi-square test. Results: Out
of 727 OPGs, 71 OPGs showed developmental alteration in tooth number. The
prevalence was 98/1000 OPGs within 3 years. Among those 71 OPGs, the gender
differences were: males (49.3%) and females (50.7%). Locations were found in
maxilla (45.1%), mandible (40.8%) and both (14.0%). The finding of delayed
eruption was (7.0%). There were significant differences between alteration in
tooth number with location as (p<0.05) while there were no significant
differences with gender and delayed eruption as (p>0.05). Conclusions: This
study showed that hyperdontia was considerably lower than hypodontia. There was
association between alteration in tooth number with location, but no
association with gender and delayed eruption.
