Dental Injuries

Dental trauma in childhood and adolescence is common. At 5 years of age 31–40% of boys and 16–30% of girls, and at 12 years of age 12–33% of boys and 4–19% of girls, will have suffered some dental trauma. Boys are affected almost twice as often as girls in both the primary and the permanent dentitions. The majority of dental injuries in the primary and permanent dentitions involve the anterior teeth, especially the maxillary central incisors. Concussion, subluxation, and luxation are the most common injuries in the primary dentition, while uncomplicated crown fractures are most common in the permanent dentition. Prognosis of traumatic injuries has improved significantly in the last 20 years. This has been largely due to a greater understanding of dental pulp reaction patterns and vital pulp therapies. Children are most accident prone between 2 and 4 years for the primary dentition and between 7 and 10 years for the permanent dentition. Coordination and judgement are incompletely developed in children during the primary dentition years, and the majority of injuries are due to falls in and around the home as the child becomes more adventurous and explores his/her surroundings. Most injuries in the permanent dentition are caused by falls and collisions while playing and running, although bicycles are a common accessory. The place of injury varies in different countries according to local customs, but accidents in the school playground remain common. Sports injuries usually occur in the teenage years and are commonly associated with contact sports. Injuries due to road traffic accidents and assaults are most commonly associated with the late teenage years and adulthood, and are often closely related to alcohol abuse. One form of injury in childhood that must never be forgotten is child physical abuse or non-accidental injury (NAI). More than 50% of these children will have orofacial injuries (see also Chapter 4, Safeguarding Children). Accidental dental injuries can result from direct or indirect trauma. Direct trauma occurs when a tooth receives a direct blow, making this sort of injury more common at the front of the mouth.

A Longitudinal Study of the Presence of Dental Anomalies in the Primary and Permanent Dentitions of Cleft Lip and/or Palate Patients

Objective The aim is to survey primary and permanent dental anomalies: hypodontia, microdontia, a supernumerary tooth, and fused teeth in patients with cleft lip and/or palate. Design Retrospective longitudinal study Subjects The subjects were selected from all 1724 patients with cleft lip and/or palate who were registered at the orthodontic clinic of Kyushu University Hospital, Fukuoka, Japan, from 1970 to 2009. Finally, 994 subjects were evaluated for primary dentition, 1352 for permanent dentition, and 871 for the longitudinal changes from primary to permanent dentition. Methods The prevalence of dental anomalies was compared for each tooth type, among various cleft types, between males and females, and between the alveolar cleft area and the noncleft area. Results The prevalence of hypodontia was 16.2% for primary dentition and 52.7% for permanent dentition in the subjects with cleft lip and/or palate. Hypodontia increased with the severity of the cleft type. Multiple hypodontia was found more frequently in the subjects with bilateral cleft lip and palate and the subjects with unilateral cleft lip and palate. Microformed lateral incisors were found in 22.7% of permanent lateral incisors but not in primary dentition. Supernumerary teeth were found in 17.7% of the subjects with cleft lip and/or palate for primary maxillary dentition and in 5.7% for permanent maxillary dentition. Conclusion The prevalence of hypodontia was greater in permanent dentition than in primary dentition; although, it was not much different between males and females or between the right and left sides. The prevalence of dental anomalies was significantly different among four groups by cleft type: cleft lip, cleft lip and alveolus, cleft lip and palate, and cleft palate.

A longitudinal study was undertaken to assess the persistance of occlusal features of the primary dentition at five years into the permanent dentition at 12 years. It was found that although there was a broad measure of predictability there was variation in detail which made forecasting unreliable in the individual patient. Generally speaking, incisal overjet and overbite changed very little between the two dentitions, but those changes which occurred were in both directions, and the direction of change could not be predicted. The sagittal relationships of the dental arch were also relatively stable, but where change occurred it tended to be in a Class II direction, with the mandibular arch becoming more retroposed in relation to the maxillary arch. The prediction of crowding of the permanent dentition from a simple count of spaces in the primary dentition, while generally reliable, was not accurate in every individual patient.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. This paper reports a rare case of the presence of a molariform mesiodens in the primary dentition. On clinical and radiographic examination, flaring of the primary central incisors was seen, with a molariform mesiodens consisting of multiple lobes or tubercles on the occlusal surface with the well-formed root. The treatment plan consisted of the extraction of the supernumerary tooth and regular observation of permanent central incisors for proper eruption and alignment.

ABSTRACTSupernumerary teeth occur frequently in permanent dentition, but they are rarely found in primary dentition. Supernumerary teeth of orthodox shape and size that resemble normal dentition are called ‘supplemental teeth’. Supplemental teeth are less common than supernumerary teeth and are often overlooked because of their normal shape and size. Supplemental teeth may cause esthetic problems, delayed eruption and crowding, and they require early diagnosis and treatment to prevent complications. The case reported here is one of bilateral supplemental teeth impeding the eruption of permanent maxillary lateral incisors, and it emphasizes the importance of early diagnosis and treatment during early mixed dentition.
