This summary is based on the article published in the American Journal of Orthodontics & Dentofacial Orthopedics: Impacted central incisors: Factors affecting prognosis and treatment duration (May 2015) Stella Chaushu, Tal Becker, and Adrian Becker Context Although the prevalence of non-eruption or impaction of the maxillary central incisor is low, its occurrence is disfiguring for a young child and of considerable concern to the parents. The causes of this phenomenon can be divided into 2 main groups: obstructive and traumatic causes. Purpose of the Study To assess the patient and treatment factors that influence the success rate and the duration ...Read More »
What are the effects of surgical anchorage techniques compared to conventional anchorage in preventing unwanted tooth movement in orthodontic treatment?
This summary is based on the Cochrane Oral Health Group review: Reinforcement of anchorage during orthodontic brace treatment with implants or other surgical methods (August 2014) Safa Jambi, Tanya Walsh, Jonathan Sandler, Philip E Benson, Richard M Skeggs, Kevin D O’Brien Context Orthodontic treatment is used to correct crooked or sticking out teeth by moving the affected teeth into the correct position. The teeth are straightened by using a brace. Sometimes unwanted movement of other teeth is caused by the use of a brace and this is controlled by what is known as anchorage, or methods for stabilizing these teeth. ...Read More »
This summary is based on the Cochrane Oral Health Group review: Orthodontic treatment for prominent upper front teeth (Class II malocclusion) in children (November 2013) Badri Thiruvenkatachari, Jayne E Harrison, Helen V Worthington, Kevin D O’Brien Context Prominent upper front teeth are a common problem affecting about a quarter of 12-year old children in the UK. The correction of this condition is one of the most common treatments performed by orthodontists. This condition develops when the child’s permanent teeth erupt and children are often referred to an orthodontist for treatment with dental braces to reduce the prominence of the teeth. ...Read More »
This summary is based on the Cochrane Oral Health Group review: Orthodontic treatment for posterior crossbites (August 2014) Paola Agostino, Alessandro Ugolini, Alessio Signori, Armando Silvestrini-Biavati, Jayne E Harrison, Philip Riley Context A posterior crossbite occurs when the top back teeth bite inside the bottom back teeth. It occurs when the top teeth or jaw are narrower than the bottom teeth and can happen on one or both sides of the mouth. The condition affects between 1% and 16% of children who only have their baby teeth. Most posterior crossbites (50% to 90%) remain even when the permanent teeth ...Read More »

What are the effects of orthodontic treatment for distalising upper first molars in children and adolescents?
This summary is based on the review published in the Chochrane database of systematic reviews: Orthodontic treatment for distalising upper first molars in children and adolescents (October 2013) Safa Jambi, Badri Thiruvenkatachari, Kevin D O’Brien, Tanya Walsh Context When orthodontic treatment is provided with fixed appliances, it is sometimes necessary to move the upper molar teeth backwards (distalise) to create space or help to overcome anchorage requirements. This can be achieved with the use of extraoral or intraoral appliances. The most common appliance is extraoral headgear, which requires considerable patient co-operation. Further, reports of serious injuries have been published. ...Read More »
How effective is preemptive analgesia on postoperative pain following third molar surgery? Review of literatures
This summary is based on the article published in the Japanese Dental Science Review: Effectiveness of preemptive analgesia on postoperative pain following third molar surgery? Review of literatures (November 2013) Akira Yamaguchi and Kimito Sano Context Surgery to remove the mandibular third molar is relatively invasive and is often associated with postoperative pain, swelling and trismus, which are frustrating for both patients and surgeons. In particular, postoperative pain increases the patient’s suffering and anxiety, and can disrupt the homeostasis of the circulatory and endocrine systems (1—3). Since it is also reported that postoperative pain can have a negative influence on wound healing, reliable and fast-onset analgesia is ...Read More »
This summary is based on the article published in Implant Dentistry: Implants for Orthodontic Anchorage: Success Rates and Reasons of Failures (April 2014) Juan C. Rodriguez, DDS, Fernando Suarez, DDS, Hsun-Liang Chan, DDS, MS, Miguel Padial-Molina, DDS, PhD, and Hom-Lay Wang, DDS, MSD, PhD Context In orthodontics, controlled forces are applied in specific directions to move teeth from improper locations into what is considered an “ideal” physiologic/esthetic location. To provide the movement, a steady and strong support known as orthodontic anchor is required. Anchorage, by definition, is a resistance to displacement provided by a static object. The most common anchor used is the patient’s own dentition; however, in some cases, the anchorage is limited or ...Read More »
