The rate of congenital tooth agenesis in patients with alveolar cleft was 72.5%, and the most common missing teeth were lateral incisors. The rate of tooth agenesis was higher in bilateral alveolar cleft (87.1%) than in unilateral alveolar cleft (67.4%). No correlation was found between gender and tooth agenesis patterns, tooth agenesis rate, or number of missing teeth. Crown width in patients with alveolar clefts is less than normal. No correlation was found between the number of missing teeth and crown width.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The congenital tooth agenesis patterns and tooth agenesis rates in patients with alveolar clefts in Guizhou, China, were related to the type of cleft, independent of gender.
