Differential premolar extractions
American Journal of Orthodontics and Dentofacial Orthopedics, 1997The primary object of this research project was to establish the amount of incisor retraction to be expected during full fixed mechanotherapy and to generate regression models that could provide more accurate prediction of each of the three most popular combinations of symmetrical premolar extractions, where extraoral anchorage would not be used ...

Prevalence of taurodontism in premolars
Oral Surgery, Oral Medicine, Oral Pathology, 1986Taurodontism does not involve molar teeth exclusively. To call attention to the occurrence of this phenomenon in premolars, 4,459 extracted mandibular and maxillary premolars were examined. Eleven showed evidence of taurodontism. Roentgenograms taken from a buccolingual direction confirmed the diagnosis of taurodont teeth.

Mandibular premolar differentiation
European Journal of Oral Sciences, 1994The authors present a method for differentiating between human mandibular premolars: P1 inf and P2 inf. The material with which the method was developed consisted of 260 stone casts. On these, both premolars were present and were intact on at least one side. The study models represented 131 girls and 129 boys, mean age 14.6 yr. In a comprehensive pilot

Duplication of the premolar dentition
Oral Surgery, Oral Medicine, Oral Pathology, 1988Multiple supernumerary teeth, often associated with various syndromes, is a relatively uncommon isolated dental anomaly. We present a case of a 9-year-old black male patient with complete duplication of the premolar dentition and premolarization of the permanent canines.

Dental Update, 2005
Tooth impaction is not uncommon among the population. Its management is important aesthetically and functionally to the patient. Treatment ranges from regular review, extraction of the primary tooth, surgical exposure of the impacted tooth, with or without orthodontic traction, auto-transplantation to its surgical removal. Any decision taken should be

Macrodontia of a mandibular premolar
Oral Surgery, Oral Medicine, Oral Pathology, 1977Abstract A case of a macrodont, dysmorphic, multitubercled mandibular premolar is described. Pathogenetically. the most likely mechanism for development of this anomaly was multiple incomplete coronal schizodontia.
