| Description | The aim of the study was to estimate the pre-, peri-, or postnatal origin of localized hypoplasia of primary canine (LHPC) and determine the most common age of death of individuals with LHPC. We also evaluated the total defect formation time and determine the average value in the months ahead. The examined file was 31 non-adults in the necropolis of Great Moravia in ZnojmoHradiště (9th and the first half of the 10th century), who had retained primary canines with LHPC. 80.0% of individuals showed postnatal hypoplastic defect, 13.3% prenatal and 6.7% (n=1) displayed both postnatal and perinatal LHPC, too. The incidence of localised hypoplasia was the same in the upper and lower teeth. In maxillary canines, the incidence of postnatal hypoplasia was very high (90.9%), in the mandibular canines also significantly prevailed but was slightly lower (81.8%). On average, therefore, the incidence of LHPC of postnatal origin was 86.4% for the examined canines. More than half of the examined individuals with LHPC died at the age of 2–5 years. Average time of formation of hypoplastic defects in the primary canines comes in our group at 4.9 months, which is comparable with literature data of 5.2 months. |
