PMID: 2152540

The presence of supernumerary teeth in the premaxillary region may cause a variety of pathological effects. This study was carried out to determine the various aspects of supernumerary teeth in the premaxillary region, particularly the effects of the supernumerary teeth on the permanent incisors and surrounding tissues. Approximately 20 percent of the patients (n = 49) with supernumerary teeth did not present with any abnormality. A high proportion of patients (37.9 percent) had delayed or failure of eruption of permanent teeth and 24.1 percent had rotation or displacement of permanent teeth. Other effects observed were median diastema and cystic changes around the unerupted supernumerary tooth. The high proportion of pathological effects seen showed that early diagnosis of the anomaly is important to intercept damage to the adjacent normal teeth and surrounding tissues. However, no cases of root resorption of the permanent teeth due to the presence of supernumeraries were observed.

PMID: 33080065 DOI: 10.1111/scd.12532

Cleidocranial dysplasia (CCD) is a rare bone disorder. The main dental features are the presence of multiple retained deciduous teeth and supernumerary teeth, as well as unerupted permanent teeth. To date, CCD is managed by a combination approach, which consists of the extraction of deciduous and supernumerary teeth, followed by orthodontic traction of unerupted permanent teeth. This case highlights the management of a girl with CCD, who refused the recommended protocol. A 15-year-old Malay female presented with a complaint of retained deciduous teeth. Intraoral examination revealed multiple retained deciduous teeth. Radiographs showed numerous impacted supernumerary and unerupted permanent teeth. The patient opted to improve her facial appearance with a less aggressive treatment option. A composite build-up on all anterior maxillary deciduous teeth was carried out until the patient was ready to undergo surgical intervention.

Fulltext Transposed Supernumerary Premolar In Alignment - A Case Report

Ngeow, W.C.

Ann Dent, 1996;3(1):-.

MyJurnal

Supernumerarypremolars have been reported to occur in 0.29% of the general populationand to represent about 9.1% of all supernumerary teeth. Most of the supernumerary teeth reported in the literature were detected by radiographsas most of them were unerupted or impacted.Asearch of the literature revealed not many cases of fully erupted and well aligned supernumerary premolars being reported. A case of a unilateral transposed supernumery premolarthat had erupted into alignment is presented here. The remarkable featureof this case is that the supernumery premolar is transposed between the first and second permanent maxillary molars. The etiology of supernumeraryteeth is also reviewed.

Hyperdontia is the condition of having supernumerary tooth, or teeth, which appear
in addition to the regular number of teeth. It is a developmental anomaly and has been argued to
arise from multiple aetiologies. It may remain embedded in the alveolar bone or can erupt into the
oral cavity. Mesiodens is a supernumerary tooth located in the anterior maxilla, placed palatally or
in between the maxillary central incisors. (Copied from article).

Introduction: Transposition is a rare dental anomaly in positional interchange between two adjacent teeth. Studies indicated that tooth transpositions are more frequent unilateral than bilateral (12:1). It is a very rare phenomenon when the anomaly is bilateral and affects same teeth on both sides. The case of a 17 year old girl, with class I incisor relationship on class 1 skeletal base with bilateral transposition of maxillary canines-first premolars, severe crowding and posterior crossbite, is presented. This case report demonstrates the orthodontic management of bilateral transposition of maxillary canines-first premolars and by the end of treatment, the transpositions were maintained while achieving a good functional and aesthetic result.

PMID: 1498045

A case report showing the eruption of the left maxillary and mandibular permanent cuspids in a six-year-old boy, is presented. In addition, the dental age of all the permanent cuspids as seen by the eruption and tooth development suggested that the cuspids are comparable to those seen in a 13 to 14 year-old-boy. A search of the literature has not revealed any such reports.

MyJurnal

Supernumerary tooth (ST) is a developmental anomaly and has been argued to arise from multiple etiologies. These teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. When it remains embedded, it may cause disturbance to the developing teeth. The erupted supernumerary tooth might cause aesthetic and/or functional problems especially if it is situated in the maxillary anterior region. A case of supernumerary teeth is presented where the teeth have been left in place and which later gave rise to some problems. The patient had history of trauma and requested orthodontic treatment for the misalignment of his anterior teeth. The treatment options are further discussed.

Mandibular third molar and angle of mandible fractures: an unsolved clinical dilemma

Rajandram R, Nabil S, Shareif M, Ishak I, Marhazlinda J, Nordin R, et al.

Sains Malaysiana, 2013;42:39-43.

The purpose of this study was to investigate the relationship between partially erupted impacted mandibular third and the risk for angle of mandible fracture. We designed a retrospective cohort study composed of patients who presented with mandible fractures. The predictor variables were the presence and angulation of the partially erupted impacted mandibular third molar and the distance between the apices of the mandibular third molar and the inferior border of the mandible. The outcome variable was the presence or absence of an angle fracture. Patients with a partially erupted impacted mandibular third molars had a 3.3 times greater chance of an angle fracture than patients without mandibular third molars (p<001). No significant association was found between the distance of the apices and angulation of the mandibular third molars to the inferior border of the mandible with angle of mandible fractures. Our findings highlight the need for enforcement of proper protective gear in young individuals who are at high risk for facial trauma.

MyJurnal

The objective of this retrospective study was to investigate what percentage of the dental students in the University of Malaya has a tooth size discrepancy. The sample comprised 40 good quality pre-treatment study models with fully erupted and complete permanent dentitions from first molar to first molar, which were selected from the dental students of the University of Malaya. The mesiodistal diameter tooth sizes were randomly measured manually from first molar to first molar using digital calliper (Mitutoyu) accurate to 0.01 mm, and the Bolton analyses for anterior and overall ratios were calculated by scientific calculator. Reproducibility analysis for intra- and interexaminer calibrations was assessed by measuring 10 study models twice, a week apart. A paired sample t-test and the correlation coefficient were used to evaluate the systematic and random errors of the measurements using Statistical Package for Social Sciences (SPSS) version 12.0. The reproducibility of the intra and inter-examiners for the sum of upper and lower mesiodistal tooth size were high (average mean difference = 0.62, r = 0.82). This study found 47.5% of the samples had anterior, and about 10% had overall· tooth width ratios greater than 2 standard deviations from Bolton's mean. Large percentage of the dental students of the University of Malaya has tooth size discrepancies outside of Bolton 2 standard deviations. It would seem prudent to routinely perform the tooth size analysis and include the findings into orthodontic treatment planning.

Fulltext Paradental Cyst Associated With an Unerupted Wisdom Tooth

Ngeow, W.C., Zain, R.B., Chai, W.L.

Ann Dent, 2000;7(1):-.

MyJurnal

The paradental cyst is an odontogenic cyst occurring near to the cervical margin of the lateral aspect of a root as a consequence of an inflammatory process in a periodontal pocket. A distinct form of the paradental cyst occurs not infrequently on the buccal aspects of erupted mandibular third molar, where there is an associated history of pericoronitis. A search of the literature revealed that these cysts had all been reported in relation to partially, newly or fully erupted molars. This report presents one case in which the cyst was noticed to be associated with an unerupted third molar. The histological appearance of the cyst and the gross relationship to the cemento-enamel junction is similar to those typical of paradental cysts reported in the literature. However, the radiographic and clinical appearance of the tooth being unerupted do not tally with paradental cyst and yet exclude the diagnosis of dentigerous cyst. The diagnosis of dental follicular tissue was excluded based on the histopathological presentation. The authors suggested that this case may represent an early form of paradental cyst which in the past may have been dismissed as dental follicular residues and thus, the prevalence of paradental cyst may have been under reported in the literature.

Fulltext Does arch length preservation in mixed dentition children affect mandibular second permanent molar eruption? A systematic review and meta-analysis

Arunachalam S, Sivakumar I, Jayaraman J, Sharan J

BMC Oral Health, 2021 08 11;21(1):395.

PMID: 34380483 DOI: 10.1186/s12903-021-01755-1

BACKGROUND: Arch length preservation strategies utilize leeway space or E-space in the mixed dentition to resolve mild to moderate mandibular incisor crowding. The purpose of this systematic review of the literature was to analyze the effects of arch length preservation strategies in on mandibular second permanent molar eruption.

METHODS: A search for relevant articles published from inception until May 2020 was performed using PubMed/Medline, Cochrane databases, Clinicaltrials.gov, Google scholar and journal databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were adopted for the conduct of the systematic review. Using RevMan 5.3 software, the most pertinent data were extracted and pooled for quantitative analysis with 95% confidence intervals. Heterogeneity was analyzed by using Cochran Q test and I squared statistics.

RESULTS: A total of 5 studies involving 855 mixed dentition patients with arch length preservation therapy were included in the qualitative analysis. Pooled estimate of the data from two studies revealed 3.14 times higher odds of developing mandibular second molar eruption difficulty due to arch length preservation strategies using lingual holding arch (95% CI; OR 1.10-8.92). There was no heterogeneity found in the analysis. The certainty levels were graded as very low.

CONCLUSIONS: This systematic review demonstrates that arch length preservation strategies pose a risk for development of mandibular second molar eruption disturbances, but the evidence was of very low quality. Registration number: CRD42019116643.
