Comparison of Immediate Implant Placement Following Extraction with and Without Socket-Shield Technique in Esthetic Region.

INTRODUCTION: Immediate implant with socket shield and immediate implant without socket shield are the two techniques which can be used to preserve the already thin labial bone in the esthetic region, thus eliminating the need for graft materials. AIM: To compare the efficacy of immediate implant placement after extraction without socket-shield technique and with socket-shield technique in the esthetic region. MATERIALS AND METHODS: Sixteen patients who reported with unsalvageable maxillary anterior teeth with labial bone thickness of less than 2 mm, depicted on preoperative CBCT, were chosen for the study and randomly assigned one of the two groups: Group A comprising socket-shield technique patients and Group B comprising immediate implant placement without socket shield. The labial bone thickness was analyzed along its entire length through CBCT scan at definite follow-up intervals up to a period of 12 months after the procedure. RESULTS: Follow-up of 1 year demonstrated a statistically significant reduction in the labial bone thickness at the crest in Group B after 8th and 12th months of implant placement. CONCLUSION: The two techniques need further comparison though our study results demonstrated better preservation of bone through the socket-shield technique, thus eliminating the need for any bony substitutes.

Study of Normal Anatomy of Mandibular Canal and its Variations in Indian Population Using CBCT.

INTRODUCTION: Identification of detailed anatomy of mandibular canal (MC) with its contents including the position, course, and morphology is extremely important for the management of various surgical procedures including dental implant placement, third molar surgery, dental anesthesia, mandibular osteotomy, bone-harvesting procedure from the ramus and body of mandible, bone plating in angle and body region of mandible, or any other surgical procedure involving the mandible. METHODS: This prospective randomized study was carried out in the Department of Oral and Maxillofacial Surgery, Saraswati Dental College, Lucknow, on 100 randomly selected cone-beam computed tomography (CBCT) mandibular views displaying the entire mandible. RESULTS: Various parameters of the canal were studied in detail and subjected to statistical analysis using SPSS 20 software. For all the observations, paired t test was applied to compare right and left sides and independent t test for the comparison of gender. CONCLUSION: For centuries MC has been a paramount topic of discussion, and with the contraption of CBCT, we can finally decipher the canal in great detail. CBCT acts as a guide to prevent damage to the neurovascular bundle as the canal traverses its course and sometimes with certain variations.

Mannitol an adjuvant in local anaesthetic solution: recent concept & changing trends (review).

Various adjuncts have been utilized with lignocaine to decrement tourniquet pain and prolong postoperative analgesia and its efficacy during dental extraction and various other restorative procedures in dentistry. An obligatory part of the dental process is to sanction a patient to feel comfortable and pain-free during operational and remedial dental procedures. The most popular local anaesthetic injection for lower teeth is the inferior alveolar nerve (IAN) block. Instead of this the percentage of ineffectiveness is higher is inferior alveolar nerve block as compared to other local anaesthetic nerve block. The goal of cumulating different drugs is to engender the best therapeutic effects with the fewest or no unpropitious effects. There are fewer researches and evidence present which recommend and promote the application and effectiveness of mannitol other than in the administration in decreasing raised intracranial pressure. It is paramount to know how the drug interacts with each other to minimize the unexpected or perilous effects.

Second primary oral melanoma: A rare presentation.

Melanomas are neoplasms of melanocytic origin. They are aggressive neoplasms with an unpredictable behavior, and can involve virtually any organ of the body. Oral melanomas are very rare and have an extremely poor prognosis. Early diagnosis and prompt treatment is the key to reduce the morbidity and mortality. A second primary tumor is a new primary tumor developing in a person with a history of tumor, in a new site or tissue and subsequent to the initial tumor. Patients with previous history of melanoma are associated with a higher risk of developing second primaries. A case of second primary oral melanoma in a 55-year-old female is reported here. The anachronistic presentation of the primary and the second primary lesions make this case clinically interesting. Noteworthy immunohistochemical findings were recorded, HMB-45 positive and S-100 negative.

Sublingual piroxicam in the management of postoperative pain after surgical removal of impacted mandibular third molar.

INTRODUCTION: Surgical removal of impacted mandibular third molar is one of the most commonly performed procedures in oral and maxillofacial surgical practice. The role of preoperative and postoperative medications for management of postoperative complications has been extensively evaluated. AIM: To assess the therapeutic effect of a single dose of 40 mg sublingual piroxicam (study group) vs 150 mg oral diclofenac (50 mg thrice a day) (control group) in patients undergoing surgical removal of impacted mandibular third molar. MATERIALS AND METHODS: A total of 100 patients with asymptomatic impacted mandibular third molars were randomized into two groups. One group received two 20-mg tablets of piroxicam once daily on the first and second postoperative days, followed by one 20-mg tablet on the third post-operative day. The other group received one tablet of diclofenac 50 mg orally thrice daily on the first, second, and third post-operative days. Repeated extraoral examinations were done for continuous assessment of swelling, trismus, and reduction in pain. Overall impression of the treating physician and the patient regarding efficacy of study drugs were recorded at the end of the study. RESULTS: In the piroxicam group there was >50% reduction in pain on all three days postoperatively. The incidence of swelling and trismus was found to be higher in the control group as compared to the study group. Adverse events, such as gastrointestinal (GI) disturbances, were significantly higher in the diclofenac group (11%) as compared to the piroxicam group (0%). CONCLUSION: Two sublingual piroxicam 20 mg tablets once daily has better efficacy and tolerability profile than diclofenac 50 mg one tablet thrice daily in the management of pain after surgical removal of impacted mandibular third molar.

Oromandibular limb hypogenesis syndrome, type IIA, hypoglossia-hypodactylia: a case report.

A patient with oromandibular limb hypogenesis syndrome, type IIA hypoglossia-hypodactylia, is reported. The features essential for the diagnosis of this congenital defect include a reduction in tongue size (microglossia), micrognathic mandible and limb abnormalities of varying severity. Parents and the other sibling were normal. Past medical history for exposure of the mother to drugs during pregnancy was positive.
