An Unusual Case of Mesial Supplementary Lateral Incisor: A Case Report

By definition, supplemental teeth are supernumerary teeth (ST) resembling adjacent teeth at the end of a tooth series and are well aligned in the arch. A case of the non-syndrome, supplemental type of supernumerary lateral incisor is presented, along with an unusual habit that was noted accidentally in the same child. In the present case, of the two lateral incisors, the mesial supplemental lateral incisor was causing an impaction of 11. In addition, the patient was aesthetically concerned. So, the decision was made to extract the supplemental tooth with altered morphology (mesial one) under local anesthesia even though, as per definition, the distal one is the supplementary tooth. And finally, to align the incisors by orthodontic treatment.

Aim

A case of the non-syndrome, supplemental type of supernumerary lateral incisor is presented, along with an unusual habit of that was noted accidentally in the same child.

Background

By definition, supplemental teeth are supernumerary teeth (ST) resembling adjacent teeth at the end of a tooth series and are well aligned in the arch.

Case description

In the present case, of the two lateral incisors, the mesial supplemental lateral incisor was causing impaction of 11. In addition, the patient was aesthetically concerned.

Conclusion

Decision was made to extract the supplemental tooth with altered morphology (mesial one) under local anesthesia even though, as per definition, the distal one is the supplementary tooth. And finally, to align the incisors by orthodontic treatment.

Clinical significance

Decision-making regarding removal of tooth is quite baffling as a selective removal of the normal or the supplementary tooth may be required and it should be made after analyzing multiple factors.

Crown Fracture of an Unerupted Incisor in a Young Child: Case Report and Restorative Protocol

Aim

This case report describes a protocol for restoring a crown fracture of an unerupted permanent incisor in a child.

Background

Crown fractures are an important concern in pediatric dentistry due to the negative impact on oral health-related quality of life (OHRQoL) in children and adolescents resulting from functional limitations as well as consequences related to social and emotional well-being.

Case description

An enamel and dentin fracture of the crown of unerupted tooth 11 due to direct trauma is being presented in a 7-year-old girl. The restorative treatment involved minimally invasive dentistry, including computer-aided design (CAD)/computer-aided manufacturing (CAM) technology and direct resin restoration.

Conclusion

The treatment decision was essential for maintaining pulp vitality and continued root development, as well as ensuring esthetic and functional results.

Clinical significance

Crown fracture of an unerupted incisor may occur in childhood, requiring a long-term clinical and radiographic follow-up. Predictable, positive, and reliable esthetic outcomes can be achieved using CAD/CAM technology combined with adhesive protocols.

Missing and unerupted teeth in osteogenesis imperfecta

INTRODUCTION

Osteogenesis imperfecta (OI) is a genetic disorder characterized by bone fragility and craniofacial and dental abnormalities such as congenitally missing teeth and teeth that failed to erupt which are believed to be doubled in OI patients than normal populations and were associated with low oral health quality of life. However, the etiology of these abnormalities remains unclear. To understand the factors influencing missing and unerupted teeth, we investigated their prevalence in a cohort of OI patients as a function of the clinical phenotype (OI type), the genetic variant type, the tooth type and the onset of bisphosphonate treatment.

METHOD

A total of 144 OI patients were recruited from The Shriners Hospital, Montreal, Canada, between 2016 and 2017. Patients were evaluated using intraoral photographs and panoramic radiographs. Missing teeth were evaluated in all patients, and unerupted teeth were assessed only in patients ≥15 years old (n = 82).

RESULTS

On average, each OI patient had 2.4 missing teeth and 0.8 unerupted teeth, and the most common missing and unerupted teeth were the premolars and the upper second molars, respectively. These phenomena were more prominent in OI type III and IV than in OI type I, and were not sex or age-related. Missing teeth were significantly more common in patients with C-propeptide variants than all other variants (p-value <0.05). Unerupted teeth were significantly more common in patients with α1 and α2 glycine variants or substitutions than in those with haploinsufficiency variants. Early-onset of bisphosphonate treatment would significantly increase the risk of unerupted teeth in patients with OI types III and IV (OR = 1.68, 95% CI (1.15-1.53)).

CONCLUSION

The prevalence of missing and unerupted teeth at the tooth type level in OI patients varies according to the nature of the collagen variants and the OI type. These findings highlight the role of collagen in tooth development and eruption.

Rare case of bilateral complex odontoma associated with mandibular bicuspids

Among oral pathologic lesions, odontomas are the most common odontogenic tumor of the jaws and generally asymptomatic. They are mostly diagnosed as a result of routine radiographic investigation. In this report, we describe a very rare occurrence of bilateral complex odontoma in the region of the mandibular second premolar. Conservative surgical procedure was planned, and removal of the odontomas was carried out through the socket after extraction of the deciduous second molars, and the diagnosis was confirmed with a histopathological study.

Orthodontic treatment of an unerupted mandibular canine tooth in a patient with mixed dentition: a case report

Background

The aim of this case report was to describe the surgical–orthodontic treatment of an unerupted mandibular canine tooth in a 9-year-old girl.

Case presentation

A 9-year-old white girl presented with an unerupted right mandibular canine tooth. Combined surgical–orthodontic treatment was performed to correct dental impaction and to achieve good aesthetic and functional results.

Conclusion

Orthodontic treatment achieved all of the required objectives.
