Pre-eruptive movements of the mandibular third molar.

1. It would appear that the developing mandibular third molar is continually changing its angular position relative to the mandibular plane and adjacent teeth. 2. For normal uprighting and eruption to occur growth at the mesial root must dominate. 3. In the absence of sufficient space, uprighting movements of the mandibular third molar may result in mesioangular impaction. 4. Vertical and distoangular impactions can be explained by continued growth at the mesial root while the crown is prevented, at its distal surface, from erupting. 5. If growth at the distal root becomes more influential, severe mesioangular or horizontal impaction may occur.

Peridontal status following surgical-orthodontic alignment of impacted teeth.

Treatment of impacted teeth is often a combination between oral surgery and orthodontics. This study evaluates the gingival condition of impacted teeth after surgical-orthodontic treatment, where two different surgical methods were used. In one group (n = 11) the teeth were radically exposed and orthodontically moved to their final position. In the other group (n = 11) the teeth were partially exposed by raising a mucoperiosteal flap. Orthodontic traction was then applied; whereafter the flap was sutured back into place. The results showed that one of the teeth in the partial exposure group and seven in the radical exposure group showed loss of attachment. This study indicates that a combination of mucoperiosteal flap technique and applied orthodontic traction is prefered to minimize the loss of attachment in cases of displaced impacted teeth.

[Possible usage of parallax phenomenon in dental radiography].

The authors describe a method of X-ray recording which uses the phenomenon of parallax in determination of exact localisation and inter-relationship of some elements within the upper and lower jaws. By describing the method in detail, the authors also point out its advantages in everyday estimation of the position of impacted teeth and their relationship to the surrounding anatomical points.

Cystic complex odontoma associated with an impacted canine.

An odontoma is a benign tumor containing all the various component tissues of teeth. Although it is the most common odontogenic tumor, it is usually discovered upon radiographic examination or later in life when it has developed into a cyst causing facial asymmetry and swelling of the face. Here is a case of a cystic complex odontoma associated with an impacted permanent canine.

Accidental displacement of impacted maxillary third molar: a case report.

An unusual case of an impacted right maxillary third molar that was accidentally displaced into the maxillary sinus during exodontia and was surgically retrieved almost 2 years later is described. The tooth was removed under general anesthesia, after maxillary sinus exposure through Caldwell-Luc approach. Postoperative recovery was uneventful. Six months after the retrieval surgery, the maxillary sinus was completely healed and the patient did not present any complaint.
