Patients frequently report sensitivity of prepared abutment teeth during the temporization period and after the final cementation of full coverage restoration. Purpose of this clinical investigation was to evaluate the effectiveness of desensitizing agents in reducing the pre- and postcementation sensitivity for full coverage restorations and to compare the relative efficacy of three in office applied desensitizing agents in relieving the postcementation sensitivity with the use of glass ionomer luting cement. Materials and methods: This study consisted of 30 patients requiring either full coverage restoration or 3 unit fixed partial denture. Total of 40 restorations (n = 40) were made and were randomly assigned into four groups comprising 10 restoration (n = 10) in each group. Group C control where no desensitizer application was done, group BB applied with BisBlock dentin desensitizer (Bisco Inc.), group ST applied with Systemp desensitizer (Ivoclar Vivadent), group GC applied with GC Tooth Mousse desensitizer (GC Asia). Desensitizer application was done immediately after the tooth preparation. Sensitivity of the tested abutment was determined by the patient response to cold, hot and bite stimuli and were recorded on visual analog scale (VAS). Sensitivity level scores was evaluated at 4 time intervals, i.e. 1 week after desensitizer application at baseline precementation appointment and others at 5 minutes, 1 day and 1 week postcementation appointment. VAS score data was statistically analyzed using one-way ANOVA followed by post hoc Tukey's test. Results: BisBlock and GC Tooth Mousse desensitizer resulted in statistically significant (p < 0.01) reduction in postcementation sensitivity of glass ionomer cement in comparison to Systemp desensitizer at 5 minutes, 1 week postcementation time interval with no statistical difference was seen between all desensitizer groups at 1 day postcementation. Application of BisBlock and GC Tooth Mousse desensitizer resulted in highly significant (p < 0.01) reduction in sensitivity level at the end of 1 week. Clinical significance: Desensitizer's application on the prepared abutment teeth is considerably effective in relieving both pre- and postcementation sensitivity for full coverage restoration over the short duration of time. Immediate reduction in postoperative sensitivity relatively in a short time period may be beneficial in terms of patient's comfort. Nonetheless, multicenter long-term clinical trials should be conducted to confirm the results. Conclusion: Efficacy of BisBlock and GC Tooth Mousse desensitizer was more in relieving the postcementation sensitivity of glass ionomer cement at various time intervals in comparison to Systemp desensitizer. In conclusion, application of desensitizers was beneficial to reduce the pre- and postcementation abutment sensitivity.

The main reason for seeking orthodontic treatment for Class II malocclusions is aesthetic improvement. Growth modification treatment procedures offer better results for a patient with significant potential growth.The aim of this cephalometric clinical study was to distinguish skeletal and dental corrections on skeletal class II division I growing subjects with Twin Block therapy (TB) and the changes were assessed using SO-analysis by Pancherz.Strict diagnostic protocol viz. growing individuals with horizontal growth pattern, skeletal class II due to retrognathic mandible with positive VTO, bilateral class II molar relation, minimal crowding in either arch or overjet more than 5mm was used. Out of 28 selected cases,17 patients received TB therapy and 11 patients were maintained as control group. Standard removable TB appliances with lower incisor capping were delivered to treatment group. The horizontal advancement was about 8mm and 2-3mm vertical opening between the upper and lower central incisors were maintained for all the cases. The mean time interval between the initial (T1)and post treatment (T2) cephalograms of Twin-Block group was 11 month,with a range of 8 month to 13 month. In the control group, the mean time interval between the first (C1)and second (C2) cephalometric films was 12 month,with a range of 10 month to 14 month.T1and T2 cephalograms were traced and S-O analysis was used to segregate dental and skeletal effects.SPSS software was used for statistical analysis.Skeletal Changes: In this study, the mean movement of maxilla was 0.67mm which represents significant restriction of forward maxillary growth in contrast to control groups. Dental Changes: In this study the maxillary molars appear to move distally with a mean value of 0.13mm. Comparing this to the movement of maxillary jaw base itself, maxillary distal movement of molar is less. But still it contributes to Class II correction.The overjet reduction and molar relation correction are more skeletal in nature.

Effective pain control during local anesthetic injection is the cornerstone of behavior guidance in pediatric dentistry. The aim of this study was to evaluate the practical efficacy of a 2-stage injection technique in reducing injection pain in children. This was a split-mouth, randomized controlled crossover trial. One hundred cooperative children aged 7 to 13 years in need of bilateral local anesthetic injections (inferior alveolar nerve block, posterior superior alveolar nerve block, or maxillary and mandibular buccal infiltrations) for restorative, endodontic, and extraction treatments were recruited for the study. Children were randomly allocated to receive either the 2-stage injection technique or conventional technique at the first appointment. The other technique was used at the successive visit after 1 week. Subjective and objective evaluation of pain was done using the Wong-Baker FACES Pain Rating Scale (FPS) and Sound Eye Motor (SEM) scale, respectively. The comparison of pain scores was done by Wilcoxon sign-rank test. Both FPS and SEM scores were significantly lower when the 2-stage injection technique of local anesthetic nerve block/infiltration was used compared with the conventional technique. The 2-stage injection technique is a simple and effective means of reducing injection pain in children. © 2016 by the American Dental Society of Anesthesiology.

Oral cavity is an uncommon site for metastasis and is usually an evidence of widespread disease. The clinical presentation of the metastatic lesions differs between the various sites in the oral region. Metastatic tumors account for 1-3% of all oral malignancies. The jawbones, particularly the mandibular molar area is more frequently affected than the oral soft tissues (2:1). Here, we report a case of a 60-year-old male patient with metastasis from lung to the mandible, where the metastasis was detected before primary tumor. © 2015 Journal of Oral and Maxillofacial Pathology.

Salivary duct carcinoma (SDC) is a rare invasive malignancy arising in the ductal epithelium of the salivary glands. These are an uncommon but distinct group of highly malignant salivary gland tumours. These are usually seen in the major salivary glands, especially in the parotid gland. This malignancy was established as a distinct clinicopathological entity and was delineated from "adenocarcinoma (NOS)" in 1991 by the World Health Organization. Salivary duct carcinomas affecting the minor salivary glands have been reported in only 4% of the SDC cases and constitute 2% of all the salivary gland malignant neoplasms. Its biological behaviour is highly aggressive; the metastatic and the tumour-related death rates were 75% and 73%, respectively. In this article, wereport a case of a salivary gland carcinoma which was present in the palate of a 55-yearold male patient.

Fusion is the union of two tooth buds that are normally separated. Fusion is more frequent in deciduous teeth, particularly in the anterior region. The etiology of fusion is not known. It has been suggested that the pressure of adjacent dental follicles produces their contact and fusion before calcification. There is no difference between men and women in incidence. The term paradental cyst means that such type of cysts that are close proximity with the root of a tooth. A history of recurrent pericoronitis is reported usually and there is often the presence of a communication between the periodontal pocket and the cyst. We present a rare case report where in partially erupted mandibular third molar is fused horizontally with a supernumerary tooth with paradental cyst.

Paget disease of bone (PDB) is a chronic progressive disease of the bone of uncertain etiology, characterized initially by an increase in bone resorption, followed by a disorganized and excessive formation of bone, leading to pain, fractures, and deformities. It can manifest as a monostotic or polyostotic disease. The prevalence of PDB is common in the Anglo-Saxon population, but relatively rare in India. The disease is often asymptomatic and commonly seen in an aging population. The diagnosis of the disease is mostly based on radiological examination and on biochemical markers of bone turnover. Markedly elevated serum alkaline phosphatase (SAP) is a constant feature while calcium and phosphate levels are typically within normal limits. It is being successfully treated by biphosphonates, a group of anti-resorptive drugs, thereby decreasing the morbidity and mortality associated with the disease. We report a classic case of PDB with craniofacial involvement resulting in Leontiasis Ossea (lion like face), cotton wool appearance of the skull and elevated SAP.

The study was conducted with the aim of comparing the shear bond strength (SBS) and microleakage of Tetric N-Bond, G-bond, and Xeno V (seventh generation dentin adhesives) in primary anterior teeth.For the shear bond strength, 45 teeth were randomly divided in to three groups namely group A, B, C (n = 15). Samples were mounted horizontally on acrylic block exposing the facial surface and bonded with different adhesives according to manufacturer instructions. A split Teflon mold was used to build the composite resin cylinder and light cured. Shear bond strength was tested using a universal testing machine. The values were statistically analysed. For microleakage, another 45 teeth were similarly grouped. Two class V cavities were prepared on the labial surface and treated with different dentine bonding agents and restored with resin composite (Ivoclar vivadent) A2 shade. The restorations were subsequently thermally stressed for 200 cycles and were subjected to dye penetration test, followed by sectioning through the center of the restoration labiolingually. Each section was examined using stereomicroscope at 40 magnification to asses dye penetration at the margins of the restoration.The SBS varied between 22.12-23.77 N/mm 2 (P-value = 0.231). The microleakage scores varied between 0.6-1.2 (P-value = 0.03; Post-hoc test A vs B (0.007)).There was a statistically higher degree of microleakage observed in group A when compared to group B.Among the three commercially available bonding agents, there were no statistically significant differences in SBS. G bond had higher microleakage when compared to the others.
