Assessment of traumatic injuries to primary teeth in general practise and specialized paediatric dentistry

DENTAL TRAUMATOLOGY, Issue 2 2010
Carl Gösta Rasmusson
Materials and methods:, A total of 323 children with traumatic injuries, 184 boys and 139 girls aged 7,83 months, participated in the study. All the children had first presented at a Public Dental Service clinic where they were examined by general dentists who decided, based on the severity of the trauma, to assign each child to one of the following two groups: Group A , recommended for treatment at the general practise (166 children with 257 traumatized incisor teeth). Group B , recommended for referral to a specialist in paediatric dentistry (157 children with 261 traumatized incisor teeth). Even in Group A, the specialist controlled the treatment decisions. The clinical diagnose and follow-up followed the recommendations presented by Andreasen & Andreasen. Results:, The distribution of trauma by age was similar in both groups, with about 60% occurring between 1 and 3 years. More injured teeth were extracted in children in Group B (n = 111) than in Group A (n = 33). A higher percentage of intruded primary incisors were recorded in Group B (24%) compared with Group A (16%). Similarly, the percentage of concussions/subluxations, lateral luxations and complicated crown fractures was higher in Group B than in Group A. Conclusions:, The group referred for specialist treatment had more severe injuries and needed more complicated treatment than the group recommended for care by general dentists. However, the rate of sequelae in permanent successors was the same in both. [source]

We evaluated the rigidity of various commonly used splints in vitro Material and Methods:, An acrylic resin model was used. The central incisors simulated injured teeth, with increased vertical and horizontal mobility. The lateral incisors and canines stimulated uninjured teeth. Tooth mobility was measured with the Periotest® device. Vertical and horizontal measurements were made before and after splinting, and the difference between values was defined as the splint effect. We evaluated 4 composite splints, 3 wire-composite splints, a titanium trauma splint, a titanium ring splint, a bracket splint, and 2 Schuchardt splints Results:, For all injured teeth and all splints, there was a significant splint effect for the vertical and horizontal dimensions (P < 0.05). For injured teeth, the composite splints produced the largest changes in vertical tooth mobility; wire-composite splints 1 and 2, using orthodontic wires, produced the smallest vertical splint effects. For uninjured teeth, the Schuchardt 1 splint and the bracket splint produced the largest splint effects; wire-composite splints 1 and 2 produced only a slight change in tooth mobility. Composite splints 2 and 3 produced the largest horizontal splint effects for injured teeth, and the 4 composite splints produced the largest horizontal splint effects for uninjured teeth. The most horizontally flexible splints were the titanium trauma splint and wire-composite splints 1 and 2. Conclusions:, According to the current guidelines and within the limits of an in vitro study, it can be stated that flexible or semirigid splints such as the titanium trauma splint and wire-composite splints 1 and 2 are appropriate for splinting teeth with dislocation injuries and root fractures, whereas rigid splints such as wire-composite splint 3 and the titanium ring splint can be used to treat alveolar process fractures.

DENTAL TRAUMATOLOGY, Issue 3 2009
Ceyhan Altun
From a total of 4956 children aged 6,12 years (mean age: 8.91 ± 1.95) applying to the Center, 472 children (9.5%) were found to have suffered dental injuries during a period of 2 years. Injuries were classified according to drawings and texts based on the WHO classification system, as modified by Andreasen and Andreasen. Injury rates were highest among children age 6 and ages 8,10. The most frequently injured permanent teeth were the maxillary central incisors (88.2%), and the maxillary right central permanent incisor made up 47.2% of all injured teeth. The most common cause of dental trauma was falling while walking or running (40.3%). Most injuries involved a single tooth (64.8%). The most common type of injury was enamel fracture (44.6%). There was a significant difference in gender, where boys more often suffered from a dental hard tissue and pulp injury than girls (P = 0.019), whereas there was no difference in gender (P = 0.248) in the distribution of periodontal injuries. Injuries were found to occur more frequently during the summer (P < 0.001). Children with increased overjet were 2.19 times more likely to have dental injuries than other children. Considering that the incidence of traumatic dental injury is highest among children ages 6 and ages 8,10 as well as the fact that patients with increased overjet are more prone to dental trauma, preventive orthodontic treatment in early mixed dentition may play an important role in reducing traumatic dental injuries.

Abstract,,, The aim of this study was to evaluate etiology, types of traumatic dental injuries, treatment and to determine the incidence of complications according to dental injuries in patients who referred to Yeditepe University, Faculty of Dentistry, Istanbul, Turkey. The study was based on the clinical data of the 161 traumatized teeth in 92 patients. WHO classification slightly modified by Andreasen & Andreasen for dental trauma was used. The causes and localization of trauma, traumatized teeth classification, treatment and complications were evaluated both primary and permanent teeth. The distribution of complications according to diagnosis and treatment of the injured teeth were evaluated. Of 35 (38%) girls and 56 (72%) boys with a mean age 7.6 ± 3.5 (ranging 1,14.2) participated to study and the mean followed up was 1.72 ± 1.28 years (ranging 0.10,3.8 years). From the 161 affected teeth, 69 (42.9%) were in primary teeth and 92 (57.1%) in permanent teeth. The highest frequency of trauma occurred in the 6,12 year age group. Overall boys significantly outnumbered girls by approximately 1:1.6. The most common type of injury in the primary and permanent teeth was seen as luxation (38%) and enamel fracture (20%) of the maxillary central incisors, respectively. Falls were the major sources of trauma both the primary (90%) and the permanent teeth (84%). In the primary dentition, the most common type of soft tissue injury is contusion (62.5%) and in the permanent dentition, it is laceration (49%). The most of the treatment choice was determined as examination only and extraction in primary teeth (58 and 24.6%, respectively) while it was applied as restoration and pulpectomy in permanent teeth (31.5 and 18.5%, respectively). Complications were recorded on 37 teeth (23%) with a most common type of necrosis (10.5%) and dental abscess (7.4%). Necrosis was more frequent in luxation whereas dental abscess were in crown fracture with pulpal involvement in both dentitions. The study showed that boys were more prone to dental traumas than girls. Falls were more frequent trauma type with a high complication risk. It reveals that the time of the immediate treatment showed the important predisposing factors that increase the success of treatment and decrease the risk of complication. The correct diagnosis of dental injuries is more important for eliminating the occurrence of complications. [source]

Abstract , The purpose of this retrospective study was to analyse data from the records of patients seen in the dental trauma emergency clinic in a general hospital in the city of Recife, Brazil, during the years 1997,1999, according to sex, age, cause, number of injured teeth, type of tooth and type of trauma. The records of all patients seen by dentists were collected. Altogether, 250 patients from 1 to 59 years of age presenting 403 dental injuries were examined and/or treated. The causes of dento-alveolar trauma were classified in five categories: home injuries, street injuries, school injuries, sports activities, violence. The type of trauma was classified by dentists working at the dental trauma clinic on the basis of Andreasen's classification. The gender difference in the number of cases of trauma was statistically significant (males 63.2% vs females 36.8) (P<0.0001). Fracture in enamel only (51.6%) and fractures in dentine (40.8%) were the most commonly occurring types of injury. Injuries were most frequently diagnosed as serious among the youngest patients (up to 15 years of age); 82.4% of intrusive luxation cases were diagnosed in the 1,5 years age group. The main causes of tooth injury were falls (72.4%), collisions with objects (9.2%), violence (8.0%), traffic accidents (6.8%) and sports (3.6%). Trauma caused by violence was found to be statistically significant in the 6,15 years age group (P<0.0005). [source]

Abstract , Information concerning age and sex distribution, etiology, types, place and extent of trauma as well as seasonal variations, time difference between traumatic injury and seeking of dental care and number of traumatic injuries was recorded retrospectively from 150 patients. The study comprised 91 boys and 59 girls representing 246 dental injuries and 332 injured teeth (72 primary and 260 permanent teeth). The most common injuries were uncomplicated crown fracture (23.57%), subluxation (15.85%), avulsion (10.16%), lateral luxation (9.75%), complicated crown fracture and intrusion (8.4% and 8.94%, respectively). The occurrence of uncomplicated crown fractures was significantly higher (P<0.05) in the 10,12 years age group than other age groups. Lateral luxation and intrusion were significantly higher in the 1,6 and 7,9 years age groups (P<0.05, respectively). [source]

Objectives. To investigate treatment provision in primary and secondary dental care following complicated crown fracture of permanent teeth. Design and methods. Retrospective observational survey of dental records of all patients attending a dental hospital trauma clinic during a 2-year period with complicated crown fracture. Results. Eighty children (70% male) aged 6,16 years (mean age 10·3 years) with 98 complicated crown fractures were identified. Of these children, 54% were seen for emergency treatment on the day of their injury, 75% within 48 h. Of the 98 injured teeth, 60% were seen initially in general dental practice but only 56% of these 59 cases were provided with emergency treatment in practice, the others being referred immediately to the trauma clinic for treatment. The main cause of fractures was transport, in particular, bicycles. Radiographs were available for 96 teeth; for the 43 open apex teeth, the definitive treatment was pulp capping (44% of cases) and pulpotomy (30%), with vitality maintained in five cases up to 4·8 years after trauma. The 53 closed apex cases were treated definitively with pulp capping (38%) and pulpectomy (36%) and six teeth had maintained their vitality up to 4·3 years after trauma. Sixty-seven per cent of the pulp caps and 47% of the 19 pulpotomies provided relied on a doubtful coronal seal. This was primarily due to the extensive use of a conventional glass ionomer cement as an emergency bandage. The use of an etched or bonded material at initial presentation extended the Median Survival Time for vitality in open apex teeth from 188 to 377 days and in closed apex teeth from 15 to 64 days. Conclusions. Emergency treatment of complicated crown fractures, particularly in primary care services is often inappropriate or inadequate with regard to emergency management of the exposed pulp and provision of a hermetic coronal seal.

Structured Abstract Authors,,, Kleine-Hakala M, Hukki J, Hurmerinta K Objective,,, To observe the effect of mandibular distraction osteogenesis (DO) on developing molars. Design,,, Descriptive clinical study. Setting,,, University hospital setting. Seventeen children (mean age 7.6 years) with various syndromes (hemifacial/craniofacial microsomia, Goldenhar syndrome, Treacher Collins syndrome, Nager syndrome and Pyle,Bakwin,Krida syndrome) participated. Experimental variable,,, Severely retrognathic lower jaws were distracted (mean 30 days) with an extraoral bicortically fixed DO device. Outcome measure,,, Consecutive panoramic tomograms were analysed after a mean follow-up period of 3.6 years, range 1,6.9 years. Results,,, The mandibular molars were affected by DO in 13 of the 17 patients which included 18 of 63 mandibular molars studied. Structural changes included root malformations, hindered tooth development and the destruction of tooth follicles. Positional changes such as shifted and tilted teeth were also found. Three injured teeth failed to erupt. These changes were because of splitting of the tooth follicle during the osteotomy (22%), piercing of the tooth follicle by the pin (39%) or migration of tooth germ towards the newly created bone (39%). Fifteen per cent of first molars, 43% of second molars and 31% of third molars were affected during the distraction process. Of all dental injuries, 44% were noticed while the appliance was in place. A further 17% of injuries were noted between 3 months and 1 year postoperatively and 33% during the second postoperative year. Conclusions,,, Although dental injuries are a minor disadvantage compared with the vast benefits offered by DO, focusing on these drawbacks might lead to re-consideration of the type of the device as well as the timing of DO.
