Patients often seek consultation with dentists for their temporomandibular disorders (TMD), especially for pain. Acute pains refer to pains that are of short duration. Common acute TMD are arthralgia and local myalgia. Diagnosis should be made based on careful history taking and clinical examination. Most acute TMD are well controlled by education, cognitive awareness training, and conservative treatment. The aggressive and irreversible treatments should not be applied. Acute TMD should be controlled in the early phase so as not to be proceed to chronic pain.

Background: Radicular pain, associated with herniated intervertebral disc, has been treated with either conservative treatments or a traditional surgical discectomy. Several modalities for minimally invasive percutaneous procedures have been developed as alternatives to a surgical discectomy. Percutaneous decompression using a $Dekompressor^{(R)}$ probe has been recently introduced. Herein, we report the outcome of percutaneous decompression with a $Dekompressor^{(R)}$ for the treatment of a herniated intervertebral disc. Methods: Between August 2004 and April 2005, percutaneous decompression was performed using a $Dekompressor^{(R)}$, 1.5-mm percutaneous lumbar discectomy probe in 17 patients with a herniated lumbar intervertebral disc resistant to conservative treatments, with the results reviewed retrospectively. The procedure was performed under fluoroscopic guidance after local anesthesia. Disc access was gained with a posterolateral approach on the symptomatic side and intradiscal placement of the discectomy probe in the herniated disc confirmed from the anteroposterior and lateral views on the fluoroscopy. Results: We obtained satisfactory clinical results in 14 patients with a decrease in the initial Visual analogue scale (VAS) of more than 55% and the elimination or reduction of analgesic medication, with a follow-up of 3 to 11 months. Conclusion: We concluded that a percutaneous discectomy with a $Dekompressor^{(R)}$ probe might be an effective alternative for the treatments of painful disc herniations resistant to conservative managements when performed under proper selection criteria.

Objectives: This study evaluated the influence of chlorhexidine (CHX) on the microtensile bonds strength (${\mu}TBS$) of resin core with two adhesive systems to dentin in endodontic cavities. Materials and Methods: Flat dentinal surfaces in 40 molar endodontic cavities were treated with self-etch adhesive system, Contax (DMG) and total-etch adhesive system, Adper Single Bond 2 (3M ESPE) after the following surface treatments: (1) Priming only (Contax), (2) CHX for 15 sec + rinsing + priming (Contax), (3) Etching with priming (Adper Single Bond 2), (4) Etching + CHX for 15 sec + rinsing + priming (Adper Single Bond 2). Resin composite build-ups were made with LuxaCore (DMG) using a bulk method and polymerized for 40 sec. For each condition, half of specimens were submitted to ${\mu}TBS$ after 24 hr storage and half of them were submitted to thermocycling of 10,000 cycles between $5^{\circ}C$ and $55^{\circ}C$ before testing. The data were analyzed using ANOVA and independent t-test at a significance level of 95%. Results: CHX pre-treatment did not affect the bond strength of specimens tested at the immediate testing period, regardless of dentin surface treatments. However, after 10,000 thermocycling, all groups showed reduced bond strength. The amount of reduction was greater in groups without CHX treatments than groups with CHX treatment. These characteristics were the same in both self-etch adhesive system and total-etch adhesive system. Conclusions: 2% CHX application for 15 sec proved to alleviate the decrease of bond strength of dentin bonding systems. No significant difference was shown in ${\mu}TBS$ between total-etching system and self-etching system.

Objectives: This in vitro study evaluated the effect of dentin biomodifiers on the immediate and long-term bond strengths of a simplified etch and rinse adhesive to dentin. Materials and Methods: Flat coronal dentin surfaces were prepared in 120 extracted human molars. Teeth were randomly divided into 5 groups (n = 24) according to 5 different surface pre-treatments: No pre-treatment (control); 1M carbodiimide (EDC); 0.1% epigallocatechin-3-gallate (EGCG); 2% minocycline (MI); 10% sodium ascorbate (SA). After surface pre-treatment, adhesive (Adper Single Bond 2 [SB], 3M ESPE) was applied. Composite was applied into transparent plastic tubes (2.5 mm in diameter), which was placed over the bonded dentin surface. From each group, 10 samples were subjected to shear bond strength (SBS) evaluation at 24 hours (immediate) and remaining 10 samples were tested after 6 months (delayed). Additionally, 4 samples per group were subjected to scanning electron microscopic analysis for observation of resin-dentin interface. The data were statistically analysed with Shaperio-Wilk W test, 2-way analysis of variance (ANOVA), and post hoc Tukey's test. Results: At 24 hours, SBS of all surface pre-treatment groups were comparable with the control group, with significant differences found between EDC and SA groups only (p = 0.009). After 6 months storage, EDC, EGCG, and MI pre-treatments preserved the resindentin bond strength with no significant fall. Conclusions: Dentin pre-treatment with all the dentin biomodifiers except SA resulted in significant preservation of resin-dentin bond over 6 months storage period, without negatively affecting the immediate bond strength of the etch and rinse adhesive tested.

In this study, compressive strengths of three condensable composite resins(ALERT, SureFil, Solitaire), conventional hybrid composite resin(Z-100) and amalgam(HI-Aristaloy 21) according to the 6 types of cavity design(cylinder, trapezoidal, butt-joint, round bevel, long bevel and short bevel) were measured and appearance of fracture surfaces were observed with SEM, thus evaluated clinical applications of condensable composite resins according to the cavity designs. The results were as follows; 1. Compressive strengths according to experimental materials were the highest in SureFil, and Z-100, ALERT, Solitaire, HI-Aristaloy 21 in order. 2. SureFil showed the highest compressive strength(p<0.05). compressive strengths of ALERT and Solitaire were lower than that of Z-100, hybrid composite(p<0.05). 3. Compressive strengths according to specimen design were the highest in trapezoidal shape(p<0.05) and no significant difference was detected between other specimen designs. 4. The appearance of condensable composite resin under SEM was of a diverse configuration according to component of resin matrix, shapes of filler and surface treatments between resin and filler.

Recently, open reduction and internal fixation has been the treatment of choice for displaced intra-articular calcaneal fractures for many orthopaedic surgeons. However controversy still surrounds the optimal treatment with regard to whether displaced intra-articular calcaneal fractures should be treated operatively or conservatively. Conservative treatments include use of splint, rest, leg elevation, icing, use of analgesics and early mobilization. Operative treatment is open reduction and internal fixation, performed through an extensile lateral approach with interfragmentary screws and application of a neutralization plate. We reviewed the question of whether operative treatment by open reduction and internal fixation provides a benefit compared with conservative treatment for displaced intra-articular calcaneal fractures.

Many articles on operative treatment strategies for osteochondral lesions of the talus (OLT) have been published. On the other hand, there are only a few reports on the conservative treatment of OLT. Understanding the natural history of OLT is essential to establishing the correct treatment. Conservative treatment might lead to comparable clinical outcomes compared to the current options of the operative treatment in isolated OLT lesions. OLT lesions can be divided into two (or possibly three) types. Hence, the prognosis and outcome of certain operative treatments should be evaluated further. The prognosis of OLT combined with instability or malalignment appears poorer than that of isolated OLT lesions. Therefore, concomitant pathologies should be evaluated together when treating patients with OLT.

Effective pain management is crucial for the successful performance of various endodontic procedures. Painless treatments are made possible by anesthetizing the tooth to be treated using various nerve-block techniques. However, certain circumstances necessitate supplemental anesthetic techniques to achieve profound anesthesia, especially in situations involving a "hot tooth" in which intrapulpal anesthesia (IPA) is employed. IPA is a technique that involves the injection of an anesthetic solution directly into the pulp tissue and is often utilized as the last resort when all other anesthetic techniques have been unsuccessful in achieving complete pulpal anesthesia. This review focuses on the IPA procedure and the factors that influence its success. Additionally, the advantages, limitations, disadvantages, and future directions of IPA are discussed.
