This review looked at the impact of premolar extraction on soft tissue profile in class II division 1 malocclusions. 13 studies were included the majority being retrospective. There is some evidence to suggest an increase in the nasolabial angle but the quality is limited.

This review of asymptomatic retained third molars included 7 prospective studies and found that the cumulative incidence for M3 extraction varied from 5 to 64% and was associated with the follow-up duration.

This new review looks at early or late premolar extraction for the orthodontic treatment of severe crowding. However, only seven retrospective studies are available so it is difficult to assess which protocol is more effective.

In a small proportion of children (1-3%) the upper permanent canine tooth is diverted into the roof on the mouth. Treatment of this displacement can be complex and it is considered that the early removal of the primary canine tooth may improve the position f the developing permanent successor. The aim of this Cochrane review [read the full story…]
Teeth are extracted every day in dental surgeries throughout the world because of tooth decay and periodontal (gum) disease. Alveolar osteitis (dry socket) is a complication that can follow an extraction with estimates of its incidence ranging from <1-37.5%. Typically a blood clot is absent in the socket and the patients have pain in and [read the full story…]
Bisphosphonates (BPs) are used for the treatment of a range of bone problems, e.g., osteoporosis, or bone metastases of malignant cancer. In 2003 the condition of bisphosphonate related osteonecrosis of the jaw (BONJ) was reported. The aim of this retrospective cohort study was to estimate the cumulative incidence and risk ratio for ONJ (osteonecrosis of [read the full story…]
Alveolar bone remodelling follows tooth extraction and traumatic extraction is associated with additional bone loss. Prior to extraction periodontal disease, periapical pathology and mechanical trauma can also lead to loss of bone. In order to maintain a good alveolar ridge a range for preservation procedures have been investigated. The aim of this review was to [read the full story…]
Dry socket (alveolar osteitis) socket is a painful complication of tooth extraction that occurs in about 5% of extractions of permanent tooth. It is more common following the extraction of wisdom teeth. That aim of this review was to assess whether chlorhexidine, when compared to placebo and/or other interventions, reduced the incidence of alveolar osteitis [read the full story…]
One of the complications of the removal of lower third molars ( wisdom teeth) is inferior alveolar nerve injury (IANI) . This has resulted in the use of a new extraction procedure coronectomy (partial odontectomy or root retention) a technique whereby the crown of a tooth is removed but parts of the roots are untouched. [read the full story…]
Third molars (wisdom teeth) generally erupt between the ages of 17-24 years. Often they fail to erupt or only erupt partially. When they do not reach their normal functional position they are considered to be impacted, this can be due to lack of space, obstruction by another tooth, or development in an abnormal position. An [read the full story…]
