Question: 1 / 1390

What percentage of malocclusion is observed after early loss of deciduous teeth?

40%

50%

60%

The correct percentage of malocclusion observed after the early loss of deciduous teeth is 60%. Early loss of primary teeth can significantly disrupt the normal alignment and spacing of the remaining teeth. When a primary tooth is lost prematurely, adjacent teeth may drift into the space, causing changes in occlusion and potentially leading to malocclusion.

Research indicates that a substantial proportion of individuals may experience malocclusion as a result of such early loss, which is why this specific percentage of 60% is cited in the literature. This statistic emphasizes the importance of maintaining the integrity of the primary dentition until the natural exfoliation occurs, as these teeth play crucial roles in dental arch development and alignment.

In contrast, the other percentages listed do not accurately reflect the findings supported by studies on this subject, making 60% the most accurate representation of malocclusion incidence following the early loss of deciduous teeth.
