The more civilized, the more incidence had happened in our daily life, particularly in industrial factories, by traffic accident, and in sports, etc. in the dental field. The accidental trauma is usually involved the teeth and surronuding tissues. And the author intended to study of the traumatic injuries of anterior teeth by individual tooth, age, sex, cause of trauma, and how they were treated. The following results were obtained: 1. The patients with traumatic injuries of the anterior teeth were 1.8% among the total dental out-patients. 2. By the age group, the twenties was most frequent in both sexes, and the teenagers next. 3. The predominant causes of traumatic injuries in the dental field were traffic accident (23.4%), fighting (19.2%), falling (18.5%), and sports (7.3%). 4. In the classification of injuries of the teeth, uncomplicated crown fractures (31.2%), subluxations (14.7%), and the complicated crown fractures (13.2%) were presented. 5. By the individual tooth in the traumatic cases, the upper cental incisors were most frequently injuried (49.8%). 6. In the treatments fillings and endodontic treatments (33.2%), splints (13.5%), extractions (11.7%) were main after care method.

Purpose: The aim of this retrospective study was to determine the association between dental implants in the posterior region and traumatic occlusion in the adjacent premolars, using data collected during from 2002 to 2015. Methods: Traumatic occlusion in the adjacent premolars was assessed by examining clinical parameters (bleeding on probing, probing pocket depth, fremitus, and tooth mobility) and radiographic parameters (loss of supporting bone and widening of the periodontal ligament space) over a mean follow-up of 5 years. Clinical factors (gender, age, implant type, maxillary or mandibular position, opposing teeth, and duration of functional loading) were evaluated statistically in order to characterize the relationship between implants in the posterior region and traumatic occlusion in the adjacent premolars. Results: The study inclusion criteria were met by 283 patients, who had received 347 implants in the posterior region. The incidence of traumatic occlusion in the adjacent premolars was significantly higher for splinted implants (P=0.004), implants in the maxillary region (P<0.001), and when implants were present in the opposing teeth (P<0.001). The other clinical factors of gender, age, and duration of functional loading were not significantly associated with traumatic occlusion. Conclusions: This study found that the risk of traumatic occlusion in the adjacent premolars increased when splinted implants were placed in the maxillary molar region and when the teeth opposing an implant also contained implants.

Purpose: The aim of this clinical trial was to explore the impact of intentional passive eruption (IPE) using occlusal reduction on the periodontal parameters of teeth with moderate chronic periodontitis and traumatic occlusion. Methods: This study was performed on 40 teeth from 16 subjects. At baseline, 4 weeks after initial periodontal treatment, and 6 months after IPE, clinical and radiographic examinations were performed. The 20 teeth in the test group underwent IPE using occlusal reduction, whereas the 20 control teeth did not undergone occlusal reduction. Results: All the periodontal parameters were improved by the initial periodontal treatment. The teeth in the test group showed a significantly greater decrease in pocket depth, tooth mobility, and marginal bone loss than did the control group (P<0.05), but there were no significant changes in the attachment level. Significantly greater improvements in all the parameters were observed in the test group after 6 months of IPE compared to 4 weeks after the initial periodontal treatment (P<0.05). Conclusions: Within the limits of this study, performing initial periodontal therapy combined with IPE using occlusal reduction was shown to be very simple and effective. Moreover, IPE would be helpful in improving periodontal parameters.

A majority of patients who sustain injuries to the peripheral sensory nerves of the face and jaws experience a slow but gradual return of sensation that is functional and tolerable, if not the same as before the injuries. However, long-term effects of such injuries are aggravating for many patients, and a few patients experience significant suffering. In some of these patients, posttraumatic symptoms become pathological and are painful. The predominant painful components are (1) numbing anesthesia dolorosa pain, (2) triggered neuralgiaform pain, (3) burning and aching causalgiaform pain, and (4) phantom pain. This is a case report of conservative management of traumatic neuralgia and neuritis as part of posttraumatic pain syndromes in geriatric patients who have undergone the teeth extraction and alveoloplasty.

Traumatic dental injury can result in avulsion of anterior teeth. In young patients, it is a challenge to the dental professional because after replantation, late complications such as ankylosis require tooth extraction. Although prosthetic and orthodontic treatment, and implant placement have been described as the options for intervention, autogenous tooth transplantation could be an effective procedure in growing patients if there is a suitable donor tooth available. This case presents the treatment of a patient who suffered a traumatic injury at 9 years old with avulsion of tooth 21, which had been replanted, and intrusion of tooth 11. Both teeth ankylosed; thus they were removed and autotransplantation of premolars was carried out. After transplantation, the tooth underwent root canal treatment because of pulpal necrosis. Orthodontic treatment began 3 months after transplantation and during 7 years' follow-up the aesthetics and function were maintained without signs of resorption.

외상성 손상은 치아 손상 자체 뿐만 아니라 악안면부의 손상을 동반하는 흔히 발생하는 현상으로 사고 발생후 외모의 손상을 일으키기 때문에 추후 환자의 사회생활에도 영향을 미칠 수 있다. 따라서 미연에 손상이 일어나는 것을 방지하는 것이 가장 중요하겠으나 이미 발생해버린 손상에 대해서 신속하고 정확한 대처를 통해 피해를 최소화할 수 있다고 하겠다. 치료의 궁극적인 목표는 사고 이전의 교합관계의 회복과 같은 기능적인 측면부터 정상적인 안모의 회복을 통한 삶의 질 향상과 같은 정신적인 측면까지 다양하다. 치과 영역의 응급상황에 특화된 분야가 아직 미흡한 상황이지만 앞에서 다룬 기본적인 초기 처치 원칙에 입각하여 진료가 이루어진다면 추후 환자에게 발생할 수 있는 추가 비용이나 합병증 등은 많이 줄어들 것으로 생각된다.

본 연구는 치아 외상의 양상과 외상 후 초진 시기의 지연이 치료에 미치는 영향에 대해 알아보고자, 2009년 1월부터 2013년 12월까지 전남대학교 치과병원 소아치과에 치아 외상을 주소로 내원한 환자 378명(외상 치아 940개)을 대상으로 기록을 조사하여 다음과 같은 결과를 얻었다. 외상의 빈도는 남자가 여자보다 2배 더 높았다. 전체 외상의 원인은 넘어짐(36.5%)이 가장 많았고, 상악 중절치(66.9%)가 가장 많이 영향을 받았다. 유치에서 가장 흔한 외상 유형은 아탈구(43.9%)였고, 영구치에서는 단순 치관파절(30.9%)이었다. 전체 환자의 10%만이 외상 후 1시간 이내에 치과에 내원하였다. 유치에서 가장 흔한 초진 시 처치는 경과관찰(53.2%)이었고, 영구치는 근관치료(27.3%)였다. 영구치에서 초진 시기의 경과에 따라 근관치료 비율은 증가하였다. 이는 외상 후 초진 시기가 늦어질수록 치수가 생활력을 잃을 가능성이 높아진다는 것을 알려준다.

The treatment of complete avulsed teeth due to traumatic injuries is replantation procedure. The major complication of replantation are pulp necrosis, ankylosis, and root resorption. It is important to maintain the vitality of periodontal ligament to minimize the complications. The purpose of this case report is to consider the facts that affect the success rate and the prognosis of complete avulsed teeth after replantation. All of these cases had different conditions and transport media. The following results were observed: 1. The successive treatment of complete ayulsed teeth requires the maintainance of vitality of periodontal ligament. 2. The complication of replantation are inflammatory root resorption and ankylosis and in such case, proper endodontic treatment using calcium hydroxide medications and periodic observations are needed. 3. In case of delayed replantation, the use of fluoride and root planning procedure can help to achieve better result. 4. It is more esthetic and functional to maintain the avulsed tooth in mouth.
