Conventional Rotary Technique and Piezosurgical Technique in the Removal of Impacted Mandibular Third Molar: A Comparative Study.

AIM: To compare the operating time, postoperative pain, edema, trismus, and patient acceptance following surgical removal of impacted third molar using piezosurgery and conventional rotary technique. MATERIALS AND METHODS: About 42 patients with impacted mesioangular mandibular third molars were included in this study. Subjects are divided into two groups: group I (treated with conventional rotary technique) and group II (treated with piezosurgery). Duration of surgery, pain, trismus, and swelling were assessed. The patients were evaluated on the 1st, 3rd, and 7th postoperative days. RESULTS: Postoperative pain, trismus, and edema were reduced with piezosurgery compared with conventional technique. Even though the duration of time was longer with piezosurgery, patient comfort was found to be better. CONCLUSION: Piezosurgery is a meticulous and innovative ultrasonic technique with selective bone cutting and better postoperative outcomes. However, it is expensive, and the operating time is prolonged. CLINICAL SIGNIFICANCE: Piezosurgery is an alternative in the surgical removal of third molars as it ensures precise and selective cutting, with no injury to the surrounding soft tissues. Postoperative outcome and patient acceptance are improved with piezosurgery.

An Observational Study on Cystic Alterations in Normal Dental Follicles Associated with Impacted Lower Third Molar for Early Intervention.

AIM: To evaluate the cystic changes in the radiographically normal dental follicle associated with impacted mandibular third molar. MATERIALS AND METHODS: This study was conducted on 80 patients. Samples were selected using a convenient sampling technique from the patients who had impacted mandibular third molars in Pell and Gregory's positions B and C, with follicular space less than 2.5 mm in diameter. After surgical removal of an impacted tooth, the dental follicle was sent for histopathologic evaluation. RESULTS: Pathologic alterations were found in 19% of cases out of 80 samples. Odontogenic keratocystic and dentigerous cystic changes were found in 7% of cases. A statistically significant cystic alteration was found in female patients and distoangular impacted teeth. CONCLUSION: This study shows a significant cystic alteration in the radiologically normal dental follicles. Clinical and radiographic features alone may not be a reliable indicator of the absence of pathology. Early intervention of impacted teeth will help to reduce morbidity due to the development of pathology. CLINICAL SIGNIFICANCE: This study will help educate patients on the risks of retaining impacted teeth, based on scientific facts, in order to minimize the risks and to assess the correlation of pathologic alterations with the depth of impaction and angular position of the impacted tooth.

Evaluation of Microbial Adherence on Antibacterial Suture Materials during Intraoral Wound Healing: A Prospective Comparative Study.

AIM: To assess the efficacy of antiseptic-coated silk sutures with triclosan-coated polyglactin 910 suture in reducing bacterial colonization after oral surgical procedures. MATERIALS AND METHODS: The patients who required multiple sutures after surgical procedures in the mandible were the study subjects. The sites of suturing were divided into three groups. Group A - surgical site receiving black-braided silk suture (control group). Group B - surgical site receiving triclosan-coated Polyglactin 910 suture (experimental group). Group C - surgical site receiving antiseptic-coated silk suture (experimental group). Evaluation was done on the 3rd postoperative and 7th postoperative day. Microbial adherence was evaluated by microbiological study. RESULTS: The mean comparison of microbial count between 3rd and 7th post-op day in the three groups shows an increased microbial colonization in the control group when compared with the experimental groups. The combined mean microbial adherence in the three groups showed microbial count in the uncoated silk suture (group A) as 10.35 ± 3.74, triclosan-coated suture (group B) as 6.28 ± 2.17 and iodoform + calendula oil-coated suture (group C) as 7.1 ± 2.02 which is statistically significant (p < 0.05). CONCLUSION: The present research concluded that the pomade-coated silk suture is as efficient as triclosan-coated VICRYL PLUS Polyglactin 910 sutures in reducing the bacterial colonization in intraoral wound healing. CLINICAL SIGNIFICANCE: The pomade (iodoform + calendula oil) may be advocated in the field of oral and maxillofacial surgery for impregnating the suture materials which act as an antiseptic agent and a promoter of wound healing which is easily accessible and also cost-effective.

Low-concentration Povidone-iodine and Normal Saline as Irrigant on Reducing Postoperative Complications after the Third-molar Surgery: A Comparative Study.

AIM: This study was conducted to compare the efficacy of using 0.5 mg/mL povidone-iodine solution as an irrigant and coolant in reducing postoperative sequelae like swelling, trismus, and pain with the conventional normal saline irrigation during the surgical removal of the impacted lower third molar. MATERIALS AND METHODS: The research was conducted out toward the MES Dental College in Perinthalmanna, Kerala, in the Department of Oral and Maxillofacial Surgery. After mandibular third-molar surgical removal, researchers studied 60 individuals, 30 of whom had normal saline irrigation (group I), and 30 of whom received 0.05% povidone-iodine irrigation (group II). The postoperative discomforts were measured on the second and seventh days after surgery, respectively. After that, the data were analyzed using SPSS. The data analysis considered p-values less than 0.05 to be significant. RESULTS: At the second postoperative visit, patients in the povidone-iodine group reported much less pain, swelling, and reduced mouth opening than those in the normal saline group. But on the seventh postoperative day, there was not much difference between either group. CONCLUSION: Following the surgical removal of teeth, it was revealed that povidone-iodine solution (0.5 mg/mL) was more effective as irrigation and cooling aid than regular saline solution. CLINICAL SIGNIFICANCE: Low-concentrated povidone-iodine is a better option in dentistry as irrigant.

Evaluation of Treatment Outcome Following Closed Reduction of Nasal Bone Fractures.

INTRODUCTION: The closed reduction of a displaced nasal fracture is a preferred method in oral and maxillofacial surgery. This prospective study was conducted to evaluate the treatment outcome following closed reduction of nasal bone fractures. MATERIALS AND METHODS: A total of 20 patients with nasal bone fracture who underwent closed reduction were included in the study. The cases were operated under local or general anesthesia. The outcome of treatment was evaluated pre- and postoperatively through systematic follow-ups. Clinical assessment was done to evaluate functional (airway patency, nasal obstruction, crepitus) as well as esthetic parameters (facial symmetry, swelling, and nasal deviation). Functional and esthetic satisfaction of patients was assessed using visual analog scale (VAS) pre- and post-operatively. RESULTS: It was observed that there was significant improvement in both functional and esthetic parameters following closed reduction of nasal fractures. CONCLUSION: The present study suggested that closed reduction of nasal bone fracture is very effective in the management of nasal bone fractures. However, further studies with larger sample size in different clinical situations should be considered to confirm the efficacy of the same. CLINICAL SIGNIFICANCE: Closed reduction can be a viable and more conservative alternative in management of nasal fractures.

Management of fascial space infections using ultrasonography as a surgical guide for drainage - A case series.

Fascial space infections are common emergencies presented to a maxillofacial surgeon. Space infection requires early diagnosis and prompt management. When left untreated, space infection spreads and involves not just one space, but also its adjacent spaces. Abscess in the head and neck region are treated by surgical incision and drainage, along with antibiotics and removal of the causative factor. The surgical incision and drainage of an abscess, if carried out based on physical examination may result in, excessive pain, tissue trauma, unnecessary extensive incisions, excess time and failure to locate and evacuate the abscess fluid. To avoid all such complications, ultrasonography is not only an invaluable diagnostic tool but also aids in ultrasonography guided drainage of fascial space infections.

Evaluating the Clinical Efficacy of Maxillary Labial Frenectomy Procedure Using Diode Laser (980 nm) and Conventional Scalpel: An Observational Study.

Aim: This is an era of minimally invasive and least traumatic surgical interventions being focused on. The traditional scalpel frenectomy technique offers an increase in post-operative sequelae. To unravel this scenario a comparative evaluation is carried out to find out the clinical outcomes and quality of life after maxillary labial frenectomy using a conventional scalpel and diode laser frenectomy of 980 nm. Materials and Methods: Thirty-six subjects age ranging between 18 and 45 years reported to the Department of Oral and Maxillofacial Surgery, MES Dental College, Perinthalmanna with an aberrant frenal attachment of maxillary labial frenum were randomly assigned into two groups. Group A underwent the conventional scalpel technique and group B for the diode laser-assisted (980 nm) frenectomy technique. The post-operative parameters of ooze from the surgical site, pain, wound healing, and discomfort or acceptance of the procedure were assessed on day 1, day 7, and day 14, respectively. Results: The diode laser group exhibited statistically significant clinical and healing outcomes. Less pain, minimal or absent ooze, increased healing, and better acceptance of the procedure with diode laser at 1, 7, and 14 days recall visit. Conclusion: Surgical interventions involving needle puncture and the associated post-operative sequelae are the most dreaded experiences that make patients indifferent toward surgical treatments. Thus in terms of better clinical outcomes and improved quality of life diode laser frenectomy is an excellent alternative wherein a needleless anesthetic success followed by minimal surgical intervention and less post-operative sequelae with fast recovery is possible.

Comparative Evaluation of Classical Inferior Alveolar Nerve Block and Gow-gates Nerve Block for Surgical Removal of Mandibular Third Molar: A Prospective Study.

BACKGROUND: The most commonly used nerve block procedure to anesthetize the mandibular arch is the classical inferior alveolar nerve block (IANB). In 1973, Gow-Gates developed a new procedure known as the Gow Gates nerve block, to achieve anesthesia in the same area with fewer complications. METHODOLOGY: The study comprised 80 patients who reported for the surgical removal of impacted third molar. The patients were randomly assigned into two groups- Group I received Gow-gates nerve block and Group II were administered classical IANB. Positive aspiration, meantime for the onset of anesthesia, mouth opening before and after each block and pain during the surgical procedure were compared. RESULTS: Group 1 yielded positive aspiration in 2.5% of the cases (one patient) and 15% had positive aspiration in Group 2 (six patient). The mean time taken for onset of anesthesia was 6.16 min in Group 1 as compared to 2.78 min in Group 2. While comparing the quality of anesthesia between the blocks, 87.5% of the patients in Group 1 and Group 2 had successful anesthesia equally i.e., 35 of the 40 patients fell into category 1 and 2 of the eight-point category rating scale in both the groups and the remaining five patients (12.5%) in both the groups had unsuccessful anesthesia. CONCLUSION: Both approaches offer quality anesthesia in the posterior mandibular area when meticulously followed. The percentage of unsuccessful anesthesia in the Gow-Gates group could be attributed to the inexperience of the operator. Postoperative comfort and patient satisfaction were greater in the other group.
