Orthodontics - 3 Questions
A cleft palate is a congenital condition that does not inherently affect statural growth. The other factors listedpoor nutrition, chronic diseases, and cardiac diseasescan all have long-term negative impacts on a person's growth and development. Poor nutrition can lead to stunted growth due to insufficient nutrients for bone and tissue development, while chronic diseases and cardiac diseases can impair the body's ability to regulate growth hormones and overall health, potentially leading to growth delays or abnormalities.
Crowding that occurs after age 18 is typically the result of physiological maturational changes. Explanation: Dental crowding is a common malocclusion where teeth do not have enough space to align properly in the dental arch. After the age of 18, most of the facial growth has concluded, and the teeth are fully erupted. If crowding occurs at this stage, it is most likely due to physiological maturational changes, such as the natural movement of teeth or the eruption of third molars (wisdom teeth). Impacted third molars are another potential cause of late crowding, but the question specifies that the crowding is not due to them. Orthodontic relapse is a possibility if the individual had prior orthodontic treatment, but without that context, the most likely cause for new crowding in adulthood is the natural shifting of teeth over time or the late eruption of wisdom teeth. Periodontal disease can affect tooth positioning, but it does not directly cause crowding.
Which dimension in which arch is considered as a safety value for pubertal growth spurts?
1) Maxillary intercanine dimension 2) Mandibular intercanine dimension 3) Maxillary intermolar width 4) Mandibular intermolar width
Intercanine width serves as safety valve for dominant horizontal basal mandibular growth spurt.
