All maxillary and mandibular teeth were aligned, the maxillary spaces were closed and the mandibular crowding
"It's widely believed that cultures vary in their tolerance to crowding
," Evans and his colleagues write.
The results showed that the difference in arch width was statistically significant along all points of measurement between crowding
and non-crowding group in both the genders with the crowding
group having smaller arch dimensions in both the genders.
Cephalogram tracings were used to determine vertical parameters such as Maxilla to Mandibular plane angle and Lower Facial height and study casts were used for Lower incisor crowding
. The Pearson Chi square test was used to determine whether vertical parameters play a significant part in the development of Lower incisor crowding
places significant stress on piping plovers and perhaps on sanderlings as well, many complicated factors underlie bird-population declines, cautions Anne Hecht, an endangered species biologist who works with Andrews.
The purpose of this study was to assess the prevalence of permanent incisor crowding
in the maxillary and mandibular arches among Saudi schoolchildren.
