Assessment of 100 children in Jerusalem with supernumerary teeth in the premaxillary region.

This retrospective study evaluated the prevalence of supernumerary teeth in the premaxilla in a group of children referred for consultation, and determines the presence of associated local disorders before and after surgical intervention. The patient files of 100 Israeli schoolchildren (72 boys and 28 girls) were reviewed. Seventy-eight percent of the 130 teeth in this study were unerupted; and 122 were surgically removed. The most common shape was conical or peg-shaped (61 percent).

An investigation into the relationship between mandibular third molars and angle fractures in Nigerians.

We examined the relationship between the presence or absence of mandibular third molars and angle fractures in Nigerians between January 1976 and July 1997. Information was obtained from patients' case records and radiographs.A total of 490 patients were seen during the study period, 408 of whom (83%) had their third molars present, and 76 of whom had angle fractures. Road traffic accidents (n =304, 62%) were the main cause of the fractures. Of these, 44 (14%) had angle fractures compared with 14/75 (19%) patients in whom the mechanism of injury was a fight or assault.Sixty-five of the 408 patients whose third molars were present (16%) had angle fractures, as did 11/82 (13%) who did not have third molars (p =0.57). Of the 77 patients whose lower third molars were not erupted, 24 (31%) had angle fractures compared with 52/331 (16%) in whom the lower third molars were erupted (p =0.002). These findings suggest that angle fractures are uncommon in this population because of their particular mechanism of injury. In addition, the presence of a lower third molar does not necessarily predispose to fractures of the angle of the mandible. However, angle fractures are more likely to occur in people with unerupted lower third molars than in those in whom they have erupted.

An assessment of root cementum in cleidocranial dysplasia.

The purpose of this prospective study was to determine if there is a difference between the amount of cellular and acellular cementum on the roots of 2 teeth extracted from a subject with cleidocranial dysplasia (CCD) compared to 10 teeth extracted from 10 subjects unaffected by CCD. The cementum of 2 permanent teeth, which had been extracted from the CCD subject, was examined and histomorphometrically analyzed for comparison to the cementum of 10 anterior teeth that had been extracted from individuals who were unaffected by CCD. The percentage of the root covered by cellular or acellular cementum was quantified to determine if patients affected by CCD typically lack cellular cementum. In the roots of the 2 permanent teeth of the subject with CCD, a mean of 18.05 +/- 10.67% was covered by cellular cementum and 76.90 +/- 3.53% was covered by acellular cementum. In the 10 permanent teeth from subjects without CCD, a mean of 19.12 +/- 15.60% of the root was covered by cellular cementum and 80.34 +/- 15.71% was covered by acellular cementum. The findings indicate that there is no statistically significant difference between the amount of either cellular or acellular cementum covering the roots of the study subject with CCD and the roots of the 10 control teeth. The presumption that a lack of cellular cementum causes the increased number of unerupted teeth in patients with CCD is not supported by the findings of this study.

Direct bonding to unerupted teeth using light-cured adhesive.

A technique is described for bonding gold traction chain directly to the enamel surface of unerupted teeth using a visible light-cured adhesive. This method obviates the need for a bracket and relies on direct, rather than transmitted illumination.

Canine ectopia: report of two cases.

Transmigration of mandibular canine is a rare elusive phenomenon described in dental literature. The eruption of such transmigrated canines is even rarer. Two rare cases one of midline mandibular canine and the other of transmigrated mandibular canine across the midline and erupted distal to the opposite lateral incisor are presented. The transmigrated canine maintained its nerve supply from the original site. It is suggested that on routine evaluation of orthopantomograms when the dentist finds an excessive mesial inclination of the unerupted mandibular canine at 8-9 years associated with proclination of lower anteriors. increased axial inclination of the unerupted canine and an enlarged symphyseal cross section area of the chin, it is best to keep such a patient under routine evaluation.

Inflammatory dentigerous cyst in a 3 year old South African black male: A case report.

We present here a case of a dentigerous cyst in the anterior maxilla of a 3 year old male. There was associated cortical expansion and facial asymmetry. These cysts are rare at this age and in addition are less common in the maxilla. Management consisted of enucleation under general anaesthetic including removal of the unerupted 11. This report attempts to highlight the importance of prompt diagnosis and referral of children with dentigerous cysts.

Eruption effects of microdontia--a case report.

A patient presented at the Department of Orthodontics, Medunsa Dental Hospital, complaining of "crooked teeth". On clinical examination it was evident that several teeth were unerupted. The absence of a normal eruption pattern of certain teeth as well as delayed eruption of others, resulted in a malocclusion.

Alkali-soluble and insoluble fluoride in erupted and unerupted human enamel from a high fluoride area with a low fluorosis score.

The amounts of fluoroapatite and 'CaF2-like' fluoride (F) were determined in enamel of unerupted and erupted teeth that had been exposed in vivo to 1.8-2.6 parts/10(6) F in the drinking water and to brushing with F dentifrice at least once a day, and occasionally to a F mouth-rinse (0.022% F). Enamel was sampled by acid-etching and the F levels were measured with an adapted F ion-selective electrode. More F was built into the deeper enamel in the high-F area than in a similar low-F area. Unerupted enamel did not etch significantly (p > 0.05) deeper than erupted enamel. No significant differences (p > 0.05) were found in the F concentrations amongst the following: alkali-washed erupted, unwashed erupted, alkali-washed unerupted and unwashed unerupted at the outer most enamel (approx. 6 microns). However the erupted enamel (alkali-washed or not) showed higher F levels than unerupted enamel (alkali-washed or not) between approx. 6 microns and greater than 100 microns. The increase of F for this high-F area was about 100% in the deeper enamel while for a low-F area it was approx. 78% in the most outer enamel with no increase after a depth of about 20 microns. In contrast to a similar low-F area (water F < 0.10 parts/10(6)), no significant 'CaF2-like' F could be detected in erupted or unerupted enamel for the high-F area.

A case of gigantiform cementoma associated with multiple unerupted teeth.

Both the occurrence of gigantiform cementoma in the jaws or multiple unerupted teeth are very rare conditions. The purpose of this paper is to report on a case of a combination of these two conditions and to review relevant literature. A 47-year-old dwarfish male was referred to our Oral and maxillofacial Surgical Department with the chief complaint of pain and swelling in the right lateral nasal region with the discharge of pus from the right upper premolar area. Clinical and roentgenographic examinations revealed that there were 17 unerupted teeth and some radiopaque and radiolucent shadows on both jaws. This patient was treated with saucerization and extraction of unerupted teeth on the right upper and lower jaws for controlling infected lesions. A surgical specimen was sent for histopathological examination and the report indicated gigantiform cementoma.

Prediction of the size of un-erupted permanent cuspids and bicuspids in a Saudi sample: a pilot study.

The purpose of this study was to produce an estimated equation for the prediction of unerupted cuspids and bicuspids for the Saudi population. In this study, dental casts of 65 Saudi subjects (37 males and 28 females) were used. The subjects' age ranged from 18 to 25 years. The mesiodistal width of all permanent teeth was measured. The data was subjected to regression analysis. Results showed the Tanaka and Johnston equations overestimate the predicted tooth width of the un-erupted cuspids and bicuspids in Saudis. Results showed the predicted tooth width of Saudis (males and females) is closer to the 50% level of confidence in Moyer's chart. Multiple regression equations were estimated including the sex factor. Accordingly, two equations were estimated for the prediction of the tooth width of the un-erupted cuspids and bicuspids for the Saudi males and females. Based on the results, it can be concluded the 50% data is more accurate than the commonly used percentage Moyer's table (75%) when both sexes are combined. Further studies are needed to confirm the findings of this study.

Pericoronal radiolucencies and the significance of early detection.

Pericoronal radiolucencies are common radiographic findings encountered in general dental practice. They usually represent a normal or enlarged dental follicle that requires no intervention; alternatively they may represent a pathological entity that requires appropriate management and histopathological interpretation. A pericoronal space of greater than 2.5mm on an intraoral radiograph and greater than 3mm on a rotational panoramic radiograph should be regarded as suspicious. Although many pathological processes may present radiographically as pericoronal radiolucencies associated with unerupted teeth, the most common is the dentigerous cyst. These lesions may enlarge considerably if allowed to develop unchecked, and have the potential for pathological transformation. In this report we present four cases of large pericoronal radiolucencies associated with unerupted teeth, and highlight the importance of early detection and management of such lesions.

The conservative approach to managing unerupted lower premolars -- two case reports.

General dental practitioners frequently refer patients with unerupted premolars for specialist management. The frequency of unerupted lower second premolars in 15-year-old children has been cited as high as 9.7%. Two cases are discussed involving unilateral unerupted premolars, which initially appear to be in unfavourable positions. The first patient was referred at 16 years of age and presented with an unerupted lower left first premolar positioned along the lower border of the mandible. The second patient presented with an unerupted distally inclined, horizontally positioned second premolar impacting on the roots of the first permanent molar. Both cases were reviewed without any treatment, and both premolars erupted into excellent positions. This raises important questions concerning the possible treatment options for such teeth as well as the timing of any interceptive treatment. In cases where premolars are unerupted or impacted, a multidisciplinary approach is indicated involving orthodontics, paedodontics and oral surgery to establish the optimal treatment plan.
