In industrialized countries, low back pam is very common, with up to 60 to 80% of the population being affected at some time in their lives. Herniated lumbar intervertebral disc is one of principal cause of low back pain and radiculopathy. The therapy of the disease is classified into conservative treatment or surgical intervention. The majority of these cases successfully heal with conservative managemant, even though it was claimed that the henirated disc material would not resolved spontaneously without surgical removal. It was reported that there was no significant difference in outcome and cost effectiveness between conservative and surgical therapy group. Also after conservative therapy the resorption of herniated disc with satisfactory improvement of symptom was reported. Conservative treatment includes bed rest, heat, drug therapy, therapeutic exercises, physical therapy such as traction and manipulation, and acupuncture. These managements show favorable outcome in the patients with herniated lumbar intervertebral disc. So conservative management should be applied in the therapy of herniated intervertebral disc, unless there exist aggravation during the first 3 weeks of treatment or apparent surgical care indication. And further investigation to improve effectiveness of conservative therapy should be ensued.

Fusion and gemination are developmental anomalies of teeth that may require endodontic treatment. Fusion may cause various clinical problems related to esthetics, tooth spacing, and other periodontal complications. Additional diagnostic tools are required for the diagnosis and the treatment planning of fused tooth. The present case report describes a case of unilateral fusion of a supernumerary root to an upper permanent central incisor with large periapical lesion in which a conservative approach was used without extraction of supernumerary tooth and obturated with mineral trioxide aggregate to reach a favorable outcome.

Purpose: This study was conducted to determine the usefulness of ultrasonography in evaluating callus formation in radiologically suspected nonunion or delayed union of clavicle fractures during conservative management. Materials and Methods: Six male patients and one female patient (average age: 38.3 years; range: 7 to 70 years), whose conservatively managed clavicle fractures were suspected of nonunion or delayed union, were examined with ultrasonography. If callus formation was detected, the patient continued to receive conservative management. If callus formation was not detected, the patient received operative management. Results: Six patients, in whom callus formation was observed ultrasonographically, continued to receive conservative management. The final simple radiographies of their fractures showed complete unions. One patient, in whom no callus formation was observed ultrasonographically, received operative management. In that patient, there was no operative finding of any fracture healing. Conclusion: Ultrasonography is a useful tool for evaluating callus formation in clavicle fractures suspected of nonunion or delayed union during conservative management. Ultrasonography can be used to avoid unnecessary surgery.

This systematic review aimed to qualitatively and quantitatively evaluate the effectiveness of cryotherapy in the reduction of postendodontic pain. The review question was, "What will be the success rate of cryotherapy technique among human patients with postendodontic pain?". The review protocol was framed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Six studies were included in the review, and quantification of five studies was performed through a meta-analysis. In the forest plot representation of the studies comparing the control and cryotherapy groups in terms of the success rate in the management of postendodontic pain, the combined risk ratio (RR) was 0.80 (95% CI: 0.56 to 1.13) with a P value of 0.20. Based on the quantitative analysis, it can be suggested that intracanal cryotherapy does not play a significant role in reducing postendodontic pain.

The purpose of this study is to categorize group of firms by using characteristics of technical innovation in telecommunication industry and to identify relationships between types of technical innovation and such contingency factors of technical innovation. The major findings of this study are summarized as follows; First, Type 1 Group (Innovative Industry Leading Group) tends to use innovative and market differentiation strategy and has more innovative C.E.O's management style and innovative culture. Second, Type 2 Group (Dependent Group on Market Change) tends to use market differentiation or cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture. Third, Type 3 Group (Small Technology Intensive Group) tends to use focused innovative strategy and has a more innovative C.E.O's management style and innovative culture. Fourth, Type 4 Group (Non-Innovative Group) tends to use focused cost leadership strategy and has a more conservative C.E.O's management style and non-innovative culture.

In the management of temporomandibular joint(TMJ) disorders, dental practioner should conduct the reversible, conservative, and inexpensive treatment modalities prior to the irreversible and invasive treatment. That is to say, behavioral, pharmacologic, and physical therapy should be conducted firstly, and then the occlusal appliance therapy could be considered. If patients do not react to these conservative treatments, we have to consider surgical treatments. If the accurate diagnosis is confirmed by intimate history taking, clinical and imaging examinations, we can rehabilitate the normal TMJ function and relieve the clinical symptoms with only conservative treatments in most TMJ disorder cases.

Tooth resorption os perplexing problem for all dental practitioners. The etiology factors and diagnosis are vague, chosen treatment dose not prevent the rapid disappearance of the calcified dental tissues. Since the etiologic factors, diagnosis, treatment and prognosis differ for these various types of resorptive defects, it is important to diagnose resorption radiographically or clinicall and distinguish internal from external resorption. Following these cases are internal root resorption, external root resorption of serious complication subsequent to avulsion and traumatic injury.

As a result of the increased participation in recreational and competitive sports activity, the incidence of chronic lateral instability has risen. Because chronic ankle instability can cause significant comorbidity and increase the social cost, the interest in this issue is growing. Although there are well-documented and effective surgical treatments for managing this condition, conservative treatments are a viable first option in selected patients. Through conservative treatment, surgical treatments can be reduced or delayed without necessarily affecting the overall outcome, but the failure of conservative treatment results in the need for surgical treatment to reduce the long term complications. Appropriate postoperative rehabilitation is essential for adequate functional recovery, even when surgical treatment is required.

Exposing sound structure of a subgingivally fractured tooth using orthodontic extrusion is considered to be a conservative way to re-establish biologic width without sacrificing esthetics or jeopardizing periodontal support of neighboring teeth. When a misaligned tooth is traumatically involved, a more comprehensive approach combining tooth extrusion and re-alignment may be necessary for a successful restorative outcome. This case report describes a successful esthetic management of a patient with complicated crown-root fracture on the maxillary right central incisor and pre-existing malocclusion in the maxillary anterior region. Forced eruption along with re-alignment of teeth by orthodontic movement seems to allow re-positioning of the fracture line to a favorable position and correction of crowding, providing a better esthetic result.

Background: The optimal management of perianal abscess in children is controversial. Purpose: To evaluate the efficiency of conservative treatment of perianal abscess in children and identify parameters that predict therapy failure. Methods: All cases of children younger than 14 years of age with perianal abscesses between 2001-2016 were evaluated. Results: Of the 113 enrolled patients, 64 underwent subsequent surgery for advanced disease (primary surgery group). Conservative treatment was initiated in 49 patients (primary conservative group) but was stopped because of inefficiency in 25 patients, who were referred for surgery after a median 7.03 days (range, 2 to 16 days). The other 24 patients (48%) initially achieved complete remission after conservative treatment, but 10 were readmitted after a median 34 months (range, 3 to 145 months) with recurrent disease. There were no significant differences in permanent success after conservative treatment between infants (10 of 29, 34%) and older children (4 of 20 [20%], P=0.122). Overall, conservative treatment alone was effective in only 14 of 113 patients. Recurrence after surgery occurred in 16 patients (25%) in the primary surgery group and 11 patients (22%) in the primary conservative group (P=0.75). Univariate analysis of predictors for conservative treatment failure revealed inflammatory values (C-reactive protein and white blood count, P=0.017) and abscess size (P=0.001) as significant parameters, whereas multivariate analysis demonstrated that only abscess size (odds ratio, 3.37; P=0.023) was significant. Conclusion: Conservative treatment of perianal abscess is permanently efficient in only a minority of children but is not associated with a higher recurrence rate after subsequent surgery. Abscess size is a predictor for therapy failure.
