The hypothesis that palatally-displaced canines are associated with smaller than average lateral incisors or with congenital absence of adjacent lateral incisors was tested on a West of Scotland population. A retrospective study of the records of orthodontic patients attending Glasgow Dental Hospital was carried out. One-hundred-and-eighty-two subjects with palatally displaced canines were identified. The tooth length of lateral and central incisors was measured on radiographs and the crown widths of lateral incisors were measured on study casts. One-hundred-and-six extracted maxillary lateral incisors were examined to allow more accurate measurement of crown width and root length than was possible from radiographs. An association was sought between the size of the lateral incisor or its absence, the position of the adjacent maxillary canine, and between crown size and root length of the lateral incisor. The conclusions supported the hypothesis that there is a weak association between palatally displaced maxillary canines and lateral incisors of smaller than average crown width. There was weak support for the association between palatal canines and absence of the adjacent lateral incisor. There was no correlation between lateral incisor crown width and root length.

Background: This study aimed to assess the accuracy of chronological age estimation based on dental measurements made on the Periapical (PA) radiographs of an Iranian adult population.   Methods: This study evaluated 90 parallel PA radiographs of sound maxillary canine teeth of 39 males and 51 females. Tooth length, root length, pulp length, pulp width, and root width at points A, B, and C according to Kvaal’s method were measured on PA radiographs using Scanora software. The collected data were analyzed using SPSS. Results: Maximum root width at point A provided the highest accuracy for gender estimation (77.7%). A significant correlation was noted between maximum pulp width at points B and C with age. Besides, a regression formula for age estimation was obtained. Conclusion: Maximum pulp width at points B and C could be used for age estimation in the adult population besides other parameters.

Tooth transposition is a relatively rare dental anomaly of interchange in position of two adjacent teeth. Aim: To determine the prevalence and distribution of canine transposition in a sample of orthodontic patients and present treatment alternatives and outcome. Study design: The records of 3000 consecutively treated orthodontic patients from a university clinic were surveyed to detect canine transposition in both dental arches. The data was recorded according to gender, age, number and location. Results: Canine transpositions were detected in 15 subjects, 3 (20%) males and 12 (80%) females presenting a prevalence of 0.5%. Of them, 6 were between the maxillary canine and first premolar, 7 between the maxillary canine and lateral incisor, 2 transpositions were between the mandibular canine and the lateral incisor. A female to male ratio of 4:1 with left side predominance was found. Treatment options include extracting the transposed teeth, maintaining them in their transposed position, or repositioning them in their normal place within the dental arch. Conclusion :The prevalence of canine transposition in the present sample was found to be 0.5% with a greater frequency in the maxilla. Treatment options include extraction of one of the transposed teeth, alignment of the teeth in their transposed position or correction of the anomaly. The latter gives the best esthetic outcome.

Two groups of subjects who demonstrated unilateral maxillary canine impaction were examined, a Caucasian group and an Oriental group. It was found that there are significant differences between the groups for sex of patients seeking treatment, site of impaction (buccal/palatal), and arch form. The Oriental group was significantly more crowded in the canine area than the Caucasian group. In almost all cases the dimensions of the lateral incisor on the side of impaction were smaller than the non-impacted side, although five subjects from the Caucasian female sub-group did not conform to this pattern, and for the Oriental male sub-group the mesiodistal crown width was larger on the impacted side.

ABSTRACT Introduction: The purpose of this study was to evaluate the prevalence of dental anomalies in a subpopulation of orthodontic patients with agenesis of maxillary lateral incisors (MLI). Methods: The material of the present study included the records of the 1964 orthodontic patients. Panoramic radiographs and dental casts were used to analyze other associated eight dental anomalies, including agenesis of other teeth, dens invaginatus, dens evaginatus, peg shaped MLI, taurodontism, pulp stone, root dilaceration and maxillary canine impaction. Results: Out of the 1964 patients examined, 90 were found to have agenesis of MLI, representing a prevalence of 4.6%. The most commonly found associated-anomalies were agenesis of other teeth (23.3%), peg-shaped MLIs (15.6%), taurodontism (42.2%), and dilacerated teeth (18.9%). Conclusion: Permanent tooth agenesis, taurodontism, peg-shaped maxillary lateral incisor, and root dilacerations are frequently associated with maxillary lateral incisor agenesis.

ABSTRACT Transposition of maxillary teeth is an eruptive disturbance occurring in approximately 1 of every 300 orthodontic patients. Such cases are frequently very challenging in terms of treatment planning and orthodontic management. The canine is one of the most commonly transposed teeth, ectopically positioned with either the lateral incisor or the first premolar. This case report illustrates unique orthodontic treatment, describes treatment procedures, and presents the final outcome of bilateral maxillary canine-lateral incisor complete transpositions in which the involved teeth were moved to their clinically normal position in the dental arch without extracting premolars.

Data were analyzed using SPSS. Results: Maximum Root width at point A had the highest accuracy for sex estimation (77.7%). A significant correlation was noted between maximum pulp width at points B and C with age and a regression formula for age estimation was obtained.

The records of 200 orthodontic patients accepted for treatment by the Orthodontic Department of the Bristol Dental Hospital in 1977 were compared with 200 taken on in 1985 in order to determine whether there had been any change in the proportion of referred cases requiring more complex procedures. Within each sample, cases were categorized as follows: (a) suitable for removable appliance treatment by an undergraduate or general practitioner; (b) requiring simple one arch fixed appliance treatment such as might he attempted by a general practitioner after a period of further training; (c) needing specialist treatment such as full multibracketed fixed appliances or orthognathic surgery. It was found that there had been no change in the proportions of simple and complex cases referred during the 8-year period although the proportion of patients now receiving complex treatment had increased greatly. Possible explanations and implications are discussed.
