RESUMO
It is of interest to assess the presence of maxillary sinus septae in patients undergoing implant treatment using Cone Beam Computed Tomography (CBCT).This retrospective study evaluated CBCT scans of 99 patients who opted for implant placement. A total of 198 sinuses were analyzed. The cases were divided into two group's namely edentulous group and non-edentulous groups. The location of septa was divided for analysis into 3 regions namely, the anterior (1st and 2nd premolar), middle (1st and 2nd molar) and posterior (behind 2nd molar) regions. Out of 198 sinuses assessed 15 sinuses had septa. It was more common in males. Mean height of septa was 7.7mm. It was more commonly seen in the middle region (1st and 2nd molar). All of the septa were partial in nature. Septa were common on the right side. It was absent in the edentulous group. To conclude this study showed low prevalence of septa in patients who were assessed as a part of pre-operative planning for implant placement. Modified sinus lift procedures were completed for placement of bone grafts in patients with septa,. This reduced the chances of membrane perforation and increases the chances of better outcomes. CBCT with its low cost and high resolution is useful for assessing the sinus.
RESUMO
Background and Objective: Impaction of the third molar teeth is a common disorder which often necessitates their removal. After third molar surgery, the common postoperative sequelae are pain, trismus, and buccal swelling. Our study sought to evaluate the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus after surgical extraction of impacted mandibular 3rd molars. Materials and Methods: Over a period of 22 months (December 1, 2016-September 30, 2018), 44 patients in the age group of 18-40 years, who required surgical extraction of impacted third molar and met the inclusion criteria were recruited. After surgical extraction of the third molar, only primary closure was performed in the control group (22 Group), whereas PRF was placed in the socket followed by primary closure in the study group (22 patients). The outcome variables were pain, swelling, and maximum mouth opening were measured with a follow-up period of 1 week. Results: The application of PRF in the study group lessens the severity of immediate postoperative sequelae such as pain, swelling, and trismus compared to the control group. Conclusion: The treatment outcomes and postoperative sequel were better in the PRF group as compared to other control group on days 1, 3, and 7 postoperatively.
RESUMO
Tooth impaction is a pathological situation where a tooth is unable to achieve its normal functional position within the expected time span. The removal may be associated with intra-operative or post-operative complications. The Le Fort I osteotomy is a procedure used by maxillofacial surgeons to correct a wide range of dentofacial deformities. Due to its versatility and simplicity, it has gained popularity for a wide range of uses. This case report describes the location and surgical removal of a right maxillary third molar which was accidentally displaced into the infratemporal fossa in a 26-year-old female while performing Le Fort I osteotomy. The patient underwent a second surgery for the retrieval of tooth using modified Gillie's temporal approach. The important role of the cone beam computed tomography in determining the localization of the displaced tooth is demonstrated.
