A 5‐year‐old boy with autism presented with an accidentally impaled toothbrush in the oral cavity. He was taken to the operation room and examined under general anesthesia. The handle of the toothbrush was cut off using rib scissors for mask ventilation, and intra‐oral intubation was performed. The toothbrush was located approximately 2.5 cm into the floor of the mouth. The toothbrush was removed uneventfully. Intravenous antibiotic therapy was instituted during hospitalization, and discharge from the hospital occurred 4 days after the operation.

The aim of this study was to evaluate the diffusion of OH− ions through root dentin by the medications: G1, Ca(OH)2/saline; G2, Calen; G3, Calen/camphorated p‐monochlorophenol (CMCP); and G4, Calen/0.4% chlorhexidine (CHX). Root canals from bovine teeth were prepared in a standardized manner. A cavity until dentin was prepared in the middle third of the root surface of each specimen. The external surface of the root was made impermeable using a layer of adhesive, except the prepared cavity. The root canals were filled with different medications, and teeth were individually stored in flasks containing...

When it is further considered that fracture and luxation injuries are often combined, the result is that more than 100 trauma scenarios exist, when the two dentitions are combined. Each of these trauma scenarios has a specific treatment demand and prospect for healing. With such a complexity in diagnosis and treatment, it is obvious that even experienced practitioners may have problems in selecting proper treatment for some of these trauma types. To remedy this situation, an Internet‐based knowledge base consisting of 4000 dental trauma cases with lon...

In the first case, the treatment of choice was follow‐up. The patient showed gingival alteration and root resorption of tooth 21. Calcium hydroxide therapy and root canal filling were performed twice because of not attending callback. After finishing the endodontic treatment, follow‐up visits showed no abnormalities. In the second case, the treatment of choice was watch and wait to the teeth 11 and 21. After 7 months spontaneous eruption of both teeth was detected. Radiographic examination showed atypical root formation and almost completely pulp canal obliteration, 8 years later. In t...

Crown fractures and luxations are the most commonly occurring of all dental injuries. Proper diagnosis, treatment planning and followup are important for improving a favorable outcome. Guidelines should assist dentists and patients in decision making and for providing the best care effectively and efficiently. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion of the IADT board...

His lower lip and upper gingiva were lacerated with swelling and epistaxis, and he had a maxillary alveolar bone fracture and severe intrusion of the right maxillary central incisor, which had penetrated the floor of the nasal cavity with avulsion. Under local anesthesia, we repositioned the incisor and bone segment and fixed them with a titanium micromesh plate and self‐tapping screws and splints. The incisor was also treated by root canal 3 days after the operation and was restored with a crown. We performed root canal filling 1 month later. Five months later, the plate and screws were removed. In prognosis of our case, no symptoms...

The material used in this study was Sports Mouthguard (3.8 mm thickness), and two holding conditions of the sheet were undertaken: one was the condition that the sheet was held all around the periphery and the other was that the sheet was held at only four points. The sheets were formed using a vacuum former when the sheets were heated until they hung 2.0 cm from the baseline. We measured the thickness of each part of the mouthguard and calculated the ratio of changes in the thickness. The difference in the thickness by the holding conditions at the area of the sheet that fitted over the anterior teeth, palate, and posterior...

Owing to the high speed, close body contact, and the combination of throwing and swimming that is inherent to the sport, the general injury potential is high. Using a standardized questionnaire for a total of 415 water polo players from Switzerland, this study examines the frequency of dental and facial injuries in water polo, athletes’ habits regarding the wearing of mouthguards, and the general level of knowledge about emergency procedures following dental trauma. The participating players came from 6 divisions: Swiss national leagues A and B, first and second leagues, as well as the women’s, and junior’s league. The data were evaluated according to division and gender. Of the 415 ...

Nevertheless, crown fractures, which are common sequelae to this type of injury, might be overlooked, especially if dental care is not sought immediately after a visit to a non‐dental facility. The present case report reviews the delayed diagnosis and treatment outcome of a bilateral posterior complicated crown fracture affecting mandibular second primary molars in a young child. Pharmacologic and orthodontic considerations are also discussed in the paper.

Pediatric mandibular fractures can have variable etiologies but have similar manifestations as those in adult patients. There are various treatment modalities to treat mandibular parasymphysis/symphysis fractures in children, which have their own limitations and complications. We currently describe our experience with open cap splint as a treatment modality which involves fewer risks in treating 10 pediatric parasymphysis/symphysis mandibular fractures.

The diagnosis is based on clinical and radiographic presentations. It might be difficult to detect VRFs in non‐endodontically treated molars by conventional radiographs in certain situations because of the limitations of 2D images and many others factors such as the VRFs being in their early stages. Root morphology variation and the orientation of VRFs can influence conventional radiographic detection and the interpretation of a radiolucent fracture line. The four case reports presented here describe and discuss the use of cone‐beam computed tomography (CBCT) in successfully diagnosing VRFs based on direct visualization of radiolucent lines, especially those suspected from ro...

Intentional replantation with 180° rotation may be a useful procedure to overcome this problem. In Case 1, a 23‐year‐old woman with complicated crown‐root fractured teeth #11, #21, and #22 was referred for treatment. All fractured teeth were extracted, rotated 180°, and replanted in a slightly extruded position. After 3 months, root canal treatment was completed and the final restorations fabricated. At the 18‐month follow up, the patient was asymptomatic, the tooth was functional, and no root resorption was observed radiographically. At the 90‐month follow up, slight cervical root resorption of tooth #11 was noted. In Case 2, a 27‐year‐old woman with a crown‐root fractured tooth #21 ...

The quality can be reduced by the image compression. The purpose of this study is to evaluate the effect of Joint Photographic Experts Group (JPEG) compressions on the diagnostic capability of periapical images in the detection of root fractures. Ten dry human mandibles containing 151 teeth were used in this study. Mandibles were radiographed with direct digital imaging sensor using the paralleling technique. Four observers detected root fracture on the images saved in one uncompressed and two compressed formats.

A total of 15 healthy female beagle dogs were used. Mandibular third and fourth premolars were endodontically treated and then extracted as atraumatically as possible. The coronal portion of each root was carefully scaled and planed. The roots on the right side of the mandible were treated with PDGF‐BB and reimplanted, while the roots on the left side served as controls. After 2, 4, or 8 weeks, specimens were collected and processed for histopathological examination. By the 4th week after reimplantation, new periodontal ligament (PDL)‐like tissue had formed around the PDGF‐BB‐treated root surfaces and new bone. By the 8th week, healin...

This clinical case reports the replacement of two central incisors that were lost because of a trauma. The advantages and disadvantages of the two treatment options (i.e. implantology or prosthetic restoration) were carefully evaluated in relation to the case in hand. Patient compliance and aesthetic requirements had been also considered. In this case, a conventional prosthetic restoration was performed using a metal‐ceramic bridge, utilising full crowns between the right and left maxillary lateral incisors associated with minimal canine preparation.

Based on a series of case reports, there appears to be evidence that new soft tissue can enter the root canal with a potential for subsequent hard tissue deposition resulting in a narrowing of the root canal. Very little is presently known about the exact nature of this tissue growing into the canal and how it may behave in the long term. In the case of regeneration of necrotic non‐infected pulp tissue, a series of clinical and histological studies have shown that such events may take place in four variants: (i) Revascularization of the pulp with accelerated dentin formation leading to pulp canal obliteration. This event has a good long‐ter...

The presence of microorganisms causes pulpal disease and further a tecidual clutter in the periradicular region. The therapy of periradicular pathosis is the consequence of a correct diagnoses which depends on the knowledge of the nature and complexity of endodontic infections. As there is no information on the microbiology of primary endodontic infection in young teeth, the aim of the current study was to investigate the microbiologic status of root canals from permanent young teeth with primary endodontic infection. Twelve patients with the need for endodontic treatment participated in the study. The selected teeth were uniradicular and had...

These conditions include teeth with: (i) exposed pulps, (ii) immature roots and pulp necrosis, (iii) root fractures and pulp necrosis located in the coronal part of the pulps, and (iv) external infection‐related (inflammatory) root resorption. The main reasons for replacing CH with MTA in these situations have generally been the delayed effect when using CH to induce hard tissues, the quality of such induced hard tissues, and finally the dentin weakening effect of CH, which in some instances lead to cervical root fractures in immature teeth. MTA appears, fro...

PDL cells were obtained from extracted healthy third molars and cultured in Dulbecco’s modified Eagles medium (DMEM). The cultures were exposed for 1, 2, 4, and 8 h to experimental solutions (tap water served as negative control and DMEM as positive control) at 37°C. The viable cells were then counted using the trypan blue exclusion technique. Data were analyzed by using one‐way anova, post hoc Scheffe and two‐way anova test. Statistical analysis showed that HBSS, powdered baby formula, and soymilk maintain cell viability equally well in different periods of times. Tap wat...

It should be emphasized and acknowledged that many cases of dental trauma are preventable. Appropriate management includes primary prevention, i.e. avoidance of pathology development, and secondary prevention, i.e. early diagnosing and treatment of the pathology before significant morbidity occurs. The aim of this article is to provide a review of the current dental trauma literature with regard to education and knowledge and with relevance to primary and secondary prevention. As the duty of providing the public with measures for the maintenance of proper oral health is of the dental profession, the responsibility of providing primary and secondary prevention of dental...

Several studies have been undertaken in an attempt to prevent, delay, or treat these complications, which are the main causes of loss of replanted teeth. This literature review examines research evidence on intracanal dressings and root canal filling materials used in cases of tooth replantation. A comprehensive search was performed in the Medline/Pubmed, Bireme and Scielo full‐text electronic journal databases to retrieve English‐language articles referring to these topics that had been published between 1964 and 2010. Calcium hydroxide (CH) remains the usually recommended choice as an intracanal medicame...

However, many preventable sports‐related dental injuries still occur even with the use of a conventional mouthguard. We have developed a mouthguard (the Hard & Space mouthguard) with sufficient injury prevention ability (more than 95% shock absorption ability against impact with a steel ball carrying 15.2 kg m2 S−2 potential energy) and ease of clinical application. This mouthguard consists of an outer and an inner EVA layer and a middle layer of acrylic resin (hard insert), with a space to prevent contact between the inner surface of the mouthguard and the buccal surfaces of the maxilla...

Endodontic treatment was performed on both teeth, and a temporary removable appliance was made for esthetics. One month later, an indirect esthetic post and core was made for each tooth, and provisionals were placed. After a 6‐month period of soft tissue stabilization, two pressed all‐ceramic crowns were fabricated and bonded to the preparations. The authors believe this to be a stable long‐term option relative to the reminiscent tooth structure, esthetic demand, and occlusal features of the case.

All cases involved young adult men. The three clinical cases involve dentin and enamel fractures, dentin and enamel fractures with pulp exposure, and dentin and enamel fractures with pulp exposure associated with root fracture. The cosmetic treatments used to resolve fractures were direct composite resin by layering technique, indirect all‐ceramic restorations (laminate veneer and ceramic crowns over the teeth), and immediate implant after extraction followed by immediate loading (ceramic abutments with ceramic crown over implant).

This case report aims to detect horizontal/oblique root fractures in posterior teeth using a combination of conventional radiographs and cone‐beam computed tomography (CBCT). Three maxillary first molars with horizontal/oblique root fractures in the palatal roots are presented. More detailed information on root fractures can be obtained using CBCT compared with conventional radiography. As such, CBCT might be a useful complementary diagnostic method to conventional radiography in cases of suspected horizontal/oblique root fractures.

Regenerative endodontic procedures include revascularization, partial pulpotomy, and apexogenesis. Several case reports give these procedures a good prognosis as an alternative to apexification. Care is needed to deliver regenerative endodontic procedures that maintain or restore the vitality of teeth, but which also disinfect and remove necrotic tissues. Regeneration can be accomplished through the activity of the cells from the pulp, periodontium, vascular, and immune system. Most therapies use the host’s own pulp or vascular cells for regeneration, but other types of dental stem cell therapies are under development. Th...

In 1991, a 7‐year‐old boy suffered a traumatic intrusion leading to an infraposition of tooth 21 along with its immobility. Based on the clinical findings, including bright‐sounding percussion testing, disappearance of the periodontal space and a failed attempt at orthodontic movement, a diagnosis of ankylosis was made. Following prosthetic restoration of the infrapositioned tooth, spontaneous re‐eruption occurred 15 years later. With the help of a partial multibracket appliance, the tooth could be adjusted to occlusal level and was then restored to the patient’s satisfaction. Radiographically, it was demonstrated that extrusi...

Disturbances during crown development of the permanent teeth result in morphologic alterations. This case report highlights the role of 3‐D imaging when conventional dental radiographs are not enough to answer our clinical questions regarding future eruptive disturbances. 3‐D imaging can many times give us a definitive diagnosis and improve the treatment planning after early injuries in the deciduous dentition. The current status of multislice computed tomography (CT) and cone beam CT (CBCT) as diagnostic tools in pediatric dental population is also discussed briefly.

Researchers recommend the use of a nose protector, but there is no standardization regarding the material employed. Clinical experience has demonstrated that a combination of a flexible and rigid layer of ethylene vinyl acetate (EVA) offers both comfort and safety to practitioners of sports. The aim of the present study was the investigation into the stresses generated by the impact of a rigid body on the nasal bone on models with and without an EVA protector. For such, finite element analysis was employed. A craniofacial model was constructed from images obtained through computed tomography. The n...

However, VRFs in teeth without endodontic treatment are relatively uncommon. VRFs are difficult to diagnose as the symptoms are non‐specific or often delayed. The most common radiographic findings are thickening of the periodontal ligament, deep, localized, vertical bone loss, and localized periradicular bone loss. The explicit feature for detecting VRFs is direct visualization of a radiolucent fracture line on radiographs. However, the fracture line can be difficult to directly visualize in conventional diagnostic methods such as periapical radiographs. If unrecognized, VRFs can lead to frustration and inappropriate endodontic treatment. The two case...

If this process develop slowly, it is possible to observe that tooth loss is characterized by a well conserved alveolus with regard to bone preservation, particularly in vertical dimension. This clinical case reports a dental trauma of a central incisor in a young boy characterized by tooth avulsion and its delayed replantation. After 10 years, dental ankylosis of the incisor was recorded and the patient underwent a prosthetic‐orthodontic rehabilitation using CAD‐CAM technology and no‐prep veneers.

Sixty human‐extracted maxillary central and lateral incisors were mounted in an acrylic block with the coronal aspect of the tooth protruding from the block surface. The teeth were assigned to two groups: 2‐mm incisal fracture and 4‐mm incisal fracture. Then, the teeth were further divided into two different restoration subgroups, porcelain laminate veneer and composite resin restoration, therefore obtaining four groups for the study (n = 15). The specimens were subjected to 1000 cycles of thermocy...

The consequences can be complex because of combined damage to the pulp, dentine, cementum, bone, and periodontium. Management of horizontal root fractures and lateral luxation depends on several factors, with the result that various clinical modalities have been suggested. This case report describes the treatment and 10‐year follow‐up of two maxillary central incisors, one with horizontal root fracture and the other with lateral luxation, treated with mineral trioxide aggregate and root canal treatment, respectively.

There is a close relationship between deciduous teeth and permanent teeth germ, and any injury in the deciduous dentition may influence the permanent teeth eruption. The extent of the damage caused to the permanent teeth germ depends on the patient age at the time of injury, type of trauma, severity, and direction of the impact. Conventional radiographic images are frequently used for diagnosis; however, recent developments in three‐dimensional (3D) imaging systems have enabled dentistry to visualize structural changes effectively, with better contrast and more details, close to the reality. The cone‐beam computed tomography (CBCT) has been used in the...

Five adult female beagle dogs were used. Thirty maxillary teeth (bilateral maxillary canines and second and fourth premolars) were randomly divided into two experimental groups (groups A and B, containing 12 teeth each) and one control group (group C). Endodontic treatment was only performed on teeth in group A compared with teeth in groups B and C. Buccal osseous dehiscence defects were surgically created in teeth from all groups. Teeth in the experimental group were treated with the EMD, whereas the controls were not. After 5 months, the animals were sacrificed and block sections of the teeth in e...

Earlier investigations have established that strain transferred to the teeth through mouthguard is a good indication of their efficiency. In the present study, a unique experimental scheme utilizing fiber Bragg gratings (FBGs) as distributed strain sensors is proposed and investigated to estimate impact absorption capability of custom‐made mouthguard. The proposed methodology is useful due to advantages such as, very small size and flexibility for ease of bonding, self‐referencing, and multiplexing capability of using FBG sensors. Material and methods: Finite‐element analysis was performed to simulate the stress distribution due to impact on the mouthguard. The FBGs w...

After performing the dissection of the soft tissues, immediate removal of the small fractures, including the tooth with small bony fragments, may be the best option, because of the difficulty incurred when attempting to retain the bone. When a large bony fragment is present, it is recommended (i) that the extraction be abandoned and surgical removal of the tooth be performed using root sectioning, (ii) that the dentist tries to detach the fractured tuberosity from the roots, or (iii) that the dentist stabilizes the mobile part(s) o...

The larvae involved in myiasis are voracious; they destroy healthy tissues and may cause serious haemorrhage. The condition can be life threatening. Six patients with craniofacial trauma and oral myiasis are reported. The diagnoses were made after larvae had been extracted. Treatment consisted of subcutaneous ivermectin therapy and the application of a phenol preparation (10% creolin) as a local measure for the control of larvae. After 12 (±1) days of hospitalization, no larvae remained in the patients’ mouths and the patients were discharged. The laboratory identified the larvae as those of the fly Cochliomyia hominivorax. Healing was uneventful in the six cases presented, ...

The research‐based background for establishment of the treatment plan is discussed. Reattachment of tooth fragment is a minimal invasive and esthetic method. Essential advantage of the reattached teeth is the fact that all the alternative methods as direct adhesive resin reconstruction, veneers and crowns can be performed in case of failure or a refracture. As a consequence of initial trauma, the tooth suffered a complicated crown fracture which was resolved by endodontic therapy and fragment reattachment. During follow‐up, the child suffered a second trauma resulting in dislodgement and fracture of the reat...

However, there was no evidence of respiratory tract impingement or deformation, including obliteration, on MR imaging. Therefore, surgical treatment involving an incision because of facial region swelling was cancelled, and the intravenous antibiotic therapy was continued. To prevent misdiagnosis and over‐treatment of young children with inflammation of the oral and maxillofacial regions, dentists, including pediatric dentists, should be aware of the clinical usefulness of MR...

A 61‐year‐old male patient had noticed pain in the right mandibular body and difficulty in mouth opening a week previously. The patient had been performing mouth‐opening training for a couple of weeks. The right lower face was slightly swollen with tenderness at the right lower border of the mandible. Hypoesthesia of the right lower lip was also observed. A bone step was palpable on the alveolar ridge of the right mandible, but mobility was not marked. The mandible was atrophic in the body region with only four anterior teeth left. Panoramic X‐ray examination revealed a moderately displaced fracture in the right molar region of the mandible. The patient had no severe ...

For several reasons, not the least ethical, such studies have to be carefully planned and important considerations have to be taken into account about suitability of the experimental model, sample size and optimizing the accuracy of the analysis. Several manuscripts of in vivo studies are submitted for publication to Dental Traumatology and rejected because of inadequate design, methodology or insufficient documentation of the results. The authors have substantial experience in experimental in vivo studies of tissue healing in dental traumatology and share their knowledge regarding critical considerations when planning experimental in vivo studies.

While the injuries were well described, not all records noted the cause or location. This has resulted in changes to the standard recording form to provide consistency in data capture. Information from this study will also be used to support child injury prevention strategies in New Zealand.

Responses from younger participants appeared to be affected by the presence of blood in photographs, while young adults were more ‘tooth‐focused.’ Younger children selected extrusion as the most painful injury, and the oldest group selected the complicated crown fracture. For the youngest age group, a missing anterior tooth was least concerning aesthetically, while young adults were most likely to choose discolouration (P < 0.05). Most in each age group thought crown fractures (particularly complicated ones) would be the most difficult for a dentist to treat. Conclusions: Statistically ...
