  For decades, losing a tooth meant only one thing: replacing it with artificial solutions such as dentures, bridges, or dental implants. But a groundbreaking scientific innovation may soon change dentistry forever. Researchers are now developing a drug capable of regrowing natural human teeth , opening the door to a new era in regenerative medicine. This discovery could transform how dentists treat tooth loss and may offer millions of people a natural alternative to artificial replacements. Why Humans Cannot Regrow Teeth Most humans develop two sets of teeth during their lifetime: baby teeth and permanent adult teeth. Once permanent teeth are lost due to decay, injury, or disease, they normally cannot grow back. However, scientists have discovered that humans still possess dormant tooth buds , which are early structures capable of forming teeth. These structures normally remain inactive because certain proteins in the body suppress their development. Recent research has fou...

The Hidden Connection Between Porphyromonas gingivalis and Alzheimer’s Disease Alzheimer’s disease is one of the most devastating neurological disorders in the world. It slowly destroys memory, thinking ability, and eventually the capacity to perform even the simplest daily tasks. For many years, scientists believed that Alzheimer’s was caused mainly by genetics and aging. However, recent research has revealed a surprising possible contributor: a bacterium that lives in the mouth. This bacterium is called Porphyromonas gingivalis , and it is commonly associated with gum disease. Scientists are now investigating whether it could also play a role in the development of Alzheimer’s disease. What is Porphyromonas gingivalis ? Porphyromonas gingivalis is a type of bacteria commonly found in the mouth, particularly in people who suffer from periodontitis , a severe form of gum disease. This bacterium thrives in the spaces between the teeth and gums, where it contributes to inflammation and ...

Care for a child’s teeth and gums can start even before the baby is born.  Pregnancy causes many hormonal changes , among these the rise of estrogen and progesterone increases the risk of developing oral health problems, like gingivitis and periodontitis .  The presence of maternal periodontal diseases and active infections has been associated with adverse pregnancy outcomes, such as preterm birth, preeclampsia, gestational diabetes and foetal loss.  Therefore, it is important to educate pregnant women about their oral hygiene and the importance of taking care of their newborn’s oral health.  J. Courtad and A. Horowitz devised six steps to help us in promoting oral health (ADA Convention- 2016 Denver):  1. Asking right questions such as “Has there been any change in your health history since your last visit?” and “When did you brush your teeth last?” is recommended in order to find out wether your patient is pregnant and to get to know her dental care better....

Dentists should always be prepared to give appropriate advice to the public about first aid for avulsed teeth .  An avulsed permanent tooth is one of the few real  emergency situations in dentistry. In addition to  increasing the public awareness by, for example, mass  media campaigns, healthcare professionals  and teachers should receive information on how to  proceed following these severe unexpected injuries. should receive information on how to  proceed following these severe unexpected injuries. Also, instructions may be given by telephone to people  at the emergency site. Immediate replantation is the  best treatment at the place of accident.  How can a dental trauma be manifested? If for some  reasons this cannot be carried out, there are alternatives such as using various storage media .  If a tooth is avulsed, make sure it is a permanent tooth  (primary teeth should not be replanted)  First aid for avul...

Little is known about the influence of biological characteristics on the occurrence of malocclusion .This study aimed to investigate the association between preterm birth and primary-dentition malocclusion and how breastfeeding and the use of pacifiers are related to this association ? Dentists should be aware that preterm birth may be a risk factor for malocclusion in primary dentition . The findings reinforce the benefits of breastfeeding on occlusal development and the negative consequences of pacifier use. In children born preterm, MSM ( moderate or severe malocclusion ) was found to be more prevalent even after adjustment for pacifier use and breastfeeding for a short period. Breastfeeding longer than 9 months reduced but did not eliminate the risk of malocclusion in preterm children.                                                   malocclusio...
