Assessment of the Smear Layer Removal Efficacy of Three Different Agents on Periodontally Compromised Tooth: An In Vitro Study.

AIM: The purpose of the present study was to evaluate the smear layer removal efficacy of three various agents on periodontally compromised tooth. MATERIALS AND METHODS: The current study included 75 molar teeth that were extracted due to periodontal disease. After that, 25 samples were randomly assigned using a simple random technique to the three different agent groups, group A: Scaling and root planing (SRP) and application of SofScale agent, group B: SRP and application of QMix agent, group C: SRP and application of MTAD agent. Using a diamond circular saw, the treated portions were divided into horizontal and vertical halves. All samples were viewed under Scanning Electron Microscope. Every tooth was focused at the coronal third, middle third, and apical third portion with a magnification of 1000×. Data were recorded and statistically analyzed. RESULTS: The smear layer removal efficacy was more in the QMix agent (3.06 ± 0.04) group followed by MTAD agent (3.28 ± 0.09) and SofScale agent (4.14 ± 0.10) group on the root surface. On intra group comparison, there was a statistically significant difference found in all the intra group agents with all the three levels. On inter group evaluation, at coronal third, there was no significant difference found between the different agents. There was a significant difference found between the different agents at middle and coronal third. CONCLUSION: On conclusion, the current investigation found that, the root surfaces treated with QMix shown a greater ability to remove smear layers compared to tooth surfaces treated with MTAD and SofScale agent. CLINICAL SIGNIFICANCE: Conventional therapies such as SRP effectively eliminate calculus, plaque, and necrosed cementum; nevertheless, they leave behind a smear layer that could impede normal healing. In an effort to overcome this, root conditioning agents were applied on the root surface to remove the smear layer. The traditional root conditioning agents such as citric acid have certain disadvantages, though, such as an acidic pH that could harm the root surface. As a result, researchers have been looking for biocompatible root conditioning treatments that are more effective. How to cite this article: Singh DK, BS Raj H, Soans CR, et al.

To Study the Impact of Tooth Sectioning on Postoperative Pain, Swelling and Trismus After Surgical Extraction of Impacted Mandibular Third Molars.

AIM: To study the impact of tooth sectioning on postoperative pain, swelling, and trismus after surgical extraction of impacted mandibular third molars. MATERIALS AND METHODS: The present research was conducted on a sample of 100 individuals who were in good health. The participants had an average age of 28 years and were seeking treatment at the Department of Oral and Maxillofacial Surgery for the extraction of impacted mandibular third molars. The participants were allocated randomly to one of the two experimental conditions. The patients in Group A are receiving a surgical procedure to remove the mandibular third molar without the need for tooth sectioning. The study focuses on patients classified as Group B who are having a surgical procedure for the extraction of the mandibular third molar using dental sectioning. RESULTS: The Group B patients saw a notable decrease in pain intensity on the third and seventh days after the surgery. The mean difference in pain scores was 4.15±0.54 and 1.69±0.11, respectively, indicating statistically significant findings with a p-value of less than 0.05. The study observed statistically significant differences in swelling between the 1st, 3rd, and 7th postoperative days for group II. The mean differences were recorded as 149.85±5.86, 119.25±4.22, and 107.52±, respectively. The significance level was determined to be P<0.05. The study observed that the degree of mouth opening in Group B exhibited a significant rise on the 3rd and 7th postoperative days, with a mean difference of 40.87±3.69 and 43.15±3.29, respectively, as compared to Group A. This difference was found to be statistically significant, with a p-value of less than 0.05.  Conclusion: The findings of our research indicate that the technique of sectioning the tooth is the preferable approach for surgical extraction of impacted third molars, as it effectively reduces the occurrence of post-operative problems.

A Comparative Evaluation of 2.0mm Two-Dimensional Miniplates Versus 2.0mm Three-Dimensional Miniplates in Mandibular Fractures.

BACKGROUND: In the past few decades, there has been an increasing interest in obtaining a more instantaneous return to normal function using diverse methods of direct fixation. AIMS AND OBJECTIVES: To compare the conventional 2-mm 2D (two-dimensional) miniplates and 2-mm 3D (three-dimensional) miniplates in terms of treatment outcome, stability, duration of surgery, and complications of treatment of symphysis and parasymphysis mandibular fractures. MATERIALS AND METHODS: 16 patients with clinical and radiological evidence of fractures of the mandible in symphysis and parasymphysis areas treated by open reduction and internal fixation with 2D miniplates and 3D miniplates. The patients were followed up for three months and assessed clinically and radiographically by taking orthopantomograms. The assessment was made on the immediate postoperative day, third day, fifth day, the seventh day, two weeks, three weeks, four weeks, two months, and three months. RESULTS: Mean intraoperative time taken for 2D miniplate was 54.8 min and for 3D miniplate was 40.6 min. Mild paraesthesia at the soft tissue region supplied by mental nerve was noticed in two patients (25%) of group I, whereas there was no such paraesthesia observed in group II patients. Wound dehiscence and infection were noticed in one patient in group I. CONCLUSION: 3D plates seem to be better than conventional 2-mm miniplates for symphysis and parasymphysis fractures.

Correlating the clinical assessment of impacted mandibular third molars with panoramic radiograph and intraoral periapical radiograph.

AIMS AND OBJECTIVES: This study was conducted to compare the clinical assessment of impacted third molars of mandible with panaromic radiograph (OPG) and intraoral periapical radiograph (IOPA) and to assess the efficacy of IOPA and. Moreover, we corroborated the OPG and IOPA findings of impacted mandiblar third molar root apex to inferior alveolar canal. MATERIALS AND METHODS: A total of 200 patients with pericoronitis were examined who were indicated for surgical extraction, among which 50 patients were selected for the study. All the patients underwent a radiographic survey with a digital OPG and IOPA of impacted mandibular third molars, along with clinical survey for anatomic relationship, type of impaction, space available, position in relation to second molar, number of roots, root curvature, and proximity of nerve canal. The data was subjected to statistical analysis. The Statistical Package for Social Sciences version 4.0.1 software was used for analyzing the collected data. RESULTS: The study revealed that IOPA was more accurate in determining a majority of the factors affecting the third molar surgery, including relationship of the external oblique ridge (IOPA vs OPG = 96%:90%), anteroposterior relation with ramus (IOPA vs OPG = 70%:66%), vertical depth of impaction (IOPA vs OPG = 72%:68%), number of roots (P = 0.013), morphology of roots (IOPA vs OPG = 96%:90%); however, OPG was found to be accurate in evaluating the type of impaction (IOPA vs OPG = 88%:94%), canal relation, along with root of impacted molar (IOPA vs OPG = 74%:86%). CONCLUSION: To conclude, although IOPA has a marginal angle over OPG in assessing various parameters, only the number of roots have a greater accuracy (P < 0.0013) in IOPA than with OPG. However, the OPG is the better choice to be considered when the patient is associated with trismus.
