AbstractThere have been infrequent case reports of bilateral root resorption in the lower second molar secondary from impacted third molar removal with bone regeneration without pain. Root resorption is commonly observed during third molar surgical impaction that affects mandibular second molars. The bone regeneration into the adjacent affected tooth is evident simply after the surgical extraction of the impacted tooth. However, there have been a few previous reports on the prognosis of the remaining resorbed tooth. Most dentists often choose to extract them when damaged if root resorption is observed. This report case involved bilateral root resorption of the lower second molar due to lower adjacent impacted third molar teeth and bone regeneration without pain sensation. After surgical extraction of bilateral lower impacted third molar teeth, the remaining teeth retained vital pulp and survived as functional teeth.

Background: The most frequently performed surgical procedure in dentistry is impacted third molar extraction with difficulty varies according to the location of the tooth. Laser therapy after surgery can accelerate cell and tissue reconstruction along with relieve post-operative pain. The objective of this study was to investigate the clinical and radiographic characteristics of impacted lower third molar and to evaluate the results of surgical extraction of impacted lower third molar with post-surgical low-level laser therapy (LLLT). Subjects and Methods: Clinical and radiographic data from 90 patients (average age 28.13 ± 5.38) subjected to a surgical extraction of lower third molar were pooled and divided randomly into 3 groups: group 1 received LLLT immediately after surgery intraorally, group 2 treated with LLLT immediately after the extraction extraorally. Patients received routine management with nonactivated laser were inserted in the control group. Assessments of pain, swelling and trismus level were carried out at 24, 48 hours and on the 7th day after surgery. Results: Correlation of wisdom teeth to ramus and adjacent teeth mainly type II (88.9%), type III accounted for 11.1%. Relative depth of wisdom teeth in the bone mainly position B (81.1%), position C (18.9%). Correlation of wisdom teeth axis to adjacent teeth: horizontal (58.9%), mesioangular impactions (40%) and distoangular impaction (1.1%). There were statistically significant decreases in the level of pain, edema and interincisal opening between the laser-treated groups and the control group on the 1st and 2nd postoperative day. Conclusions: Intraoral and extraoral post-surgical low-level laser therapy treatment was useful in reducing swelling, pain and trismus compared to placebo group in impacted third molar surgery. Key words: Impacted lower third molar, low- level laser therapy

Volume Measurements

The aim of this article is to describe a large mandibular cyst treated with decompression followed by surgical enucleation. Furthermore, we described the utility of cyst volume measurements by using a 3D reconstruction on Cone Beam Computed Tomography (CBCT). The dentigerous cyst is the most common cyst type of epithelial origin, arising from remnants of odontogenic epithelium, asymptomatic and associated with the crown of an unerupted or partially or completely impacted tooth. However, after a long duration and extension of the cyst volume it may provoke significant bone resorption, cortical expansion, tooth displacement and the vitality of neighboring teeth may be affected. The regular treatment of this lesion is enucleation and extraction of the involved tooth. Marsupialization and decompression are proposed when the volume of the cyst is well developed to release the cystic pressure and allow the bone cavity to progressively decrease in volume with the gradual apposition of bone. This report presents a large dentigerous cyst related to impacted mandibular third molar of a 21-year-old male patient. The cyst was treated successfully by decompression and later by surgical enucleation with surgical extraction of the related molar. In conclusion, the combination of decompression and surgical approach showed on the three-dimensional CBCT investigation a significant correlation between the treatment and volume reduction of the cyst. The clinical case described allows us to observe bone formation after decompression and surgical enucleation was performed with less risk on vital anatomic elements.

Objectives: To compare the difference in mean trismus by giving two doses of Dexamethasone after surgical extraction of impacted mandibular third molar. Study Design: Randomized controlled clinical trial. Period: 1st Jan 2016 to 30thJune 2017. Setting: Out Patient Department of Oral & maxillofacial Surgery, Nishtar Institute of Dentistry Multan. Methodology: Data was entered on SPSS version 23 and mean ± SD were calculated for quantitative variables like age and mouth opening in mm. Similarly frequency and percentage of qualitative variables were calculated and presented like gender and incidence of trismus. P value ≤ 0.05 was considered as significant. Results: There were 60 patients in total. Males were 31 (51.7%) while females were 29 (48.3%) (Graph-1). Mean age of the patients was 37.25 + 9.04 years ranging from a minimum of 20 to a maximum of 50 years. When students t-test was applied to compare the means of two groups, in group A the mean trismus was found to be 25.77 + 3.58 mm while in group B the mean trismus was found to be 35.53 + 5.11 mm. The t-value was found to be 8.56 and df 58. The p-value was found to be < 0.0001 which was clinically significant. Conclusion: The dosage of 8 mg of dexamethasone was statistically more significant in the reduction of trismus as compare to 4mg (p-value =0.000). So it is recommended that Dexamethasone with dosage of 8mg should be used to control postoperative trismus after surgical extraction of mandibular impacted third molar.

Objectives: To evaluate the severity of post-operative pain after surgical extraction of impacted mandibular third molar using two different techniques i.e. comma incision and standard Wards incision. Study Design: Interventional study. Setting: Department of Oral surgery, Isra Dental College Hospital. Period: From January 2016 to June 2016. Material & Methods: A sample of 50 patients of impacted third molar was selected by non-probability purposive sampling for tooth extraction either by conventional technique or by coma shaped incision. Post-operative amount of pain was measured on 1st, 3rd and 7th day respectively. Results: Mean ± SD age in group A and B was noted as 28.5 ± 4.32 and 27.2 ± 4.39 years respectively. Male and female in groups A and B were noted as 16 (64%) and 9 (36%), & 14 (56%) and 11 (44%) respectively. Right and left lower mandibular teeth extraction in groups A and B were noted 11 and 14, & 10 and 15 respectively. Pain was measured after extraction at day 1, day 3 and day 7. Conclusion: The Coma incision was preferable over the conventional method- the standard Ward`s incision because of lesser degree of post-operative pain.
