 Hello everyone welcome back to a new session on dentistry and more so today We have a very interesting topic that is ugly deckling stage or brawl pen phenomenon so all of us have faced or went through this stage that is ugly deckling stage during our early school years Where our teeth looked very weird especially the front teeth it was flared up But after a few years it got character automatically So what is exactly? Ugly deckling stage and why it is known as ugly deckling so broadband been a phenomena. It is we can say that it was Explained by a person broadband, but why it is known as ugly deckling stage. So let's see what is Ugly deckling stage or broadband phenomena. So ugly deckling stage. It is nothing but a peculiar appearance of our upper teeth during a period of eight to nine years or eight to ten years it was literally ugly because the teeth were flared up there was midline diastema But why it is known as ugly deckling stage It is based upon a story that is given by it is a Danish story for a fairytale by Danish poet and author hands Christian Anderson So he published a story of ugly deckling So the story says about a duckling The duckling found herself to be very ugly when it was born But once the duckling having full grown and matured The duckling found out that Let's become a beautiful swan that ugly phase was very short and It was a self-corrected one. So it was just a Comparison a self-corrected problem or a psychological problem He connected the problem of this incisor flare-up and the weird-looking teeth to this story that is ugly duckling stage Now let's see what is happening inside our teeth When the canine erupts so it all starts with the permanent canines So it is a Transitional phase. Okay. So what happens is normally the central incisor and lateral incisor it erupts during 6 to 8 years 7 years 8 years it is erupted Now what happens is the canines the permanent canines which are very big the longest tooth It has a big ground it has very lengthier roots and it is very bulkier So when it erupts what happens is it applies pressure on the roots of lateral incisor from both sides Okay, so this blue is canine it applies pressure on the lateral roots So what happens is the root? takes up the force and it In turn transfer the force to central incisor root and all the forces are directed towards the mesial side From here it is going mesial side and it is theory. It is going mesial side. So when roots are Converging or it is moving mesial side What happens? The crowns are moving distally. Okay, so it just rotates The roots moving mesially at the same time crowns Moving distal side and there will be a diastema formation and it looks very weird But after a later period of time that is it continuously reps So it is erupting it is coming Here and here it is reaching the crown region Still it applies pressure, but now it is applying pressure on the crown instead of root So what happens? The crowns are moving mesial side from both the ends from right and left ends the crowns are Converging the roots are going back to its original position So when the canine erupts it first applies the pressure on roots Then it is on the crown. So both the time it moves mesial side So when it is applying on the roots the crown diverges and this ugly decaling stage or broadband phenomena Seen but when it is completely erupted when it is reaching to its occlusion Plane the force is transmitted to crown the crown is going back to its original position The root is coming back to its original position And the person or the child is having the normal occlusion or the normal appearance So that is about ugly decaling stage. It is a very transient or self-correcting malocclusion Transient means it takes two to three years once it Completely erupted it will be over. So there will be flaring of lateral incisor, madeleine dastema formation Then canine erupts it reaches the normal occlusion So that is ugly decaling stage or broadband phenomena It is a very simple concept canine erupts replace pressure crown diverges Canine completely erupts it applies pressure on crown it goes back to the normal Occlusion or normal alignment. So that's all about this concept ugly decaling stage and Our broadband phenomena. I will come up with a new topic on dentistry and more. Thank you
