Asymmetric hologram having a single-size nanostructured metasurface.
05 was taken as statistically significant.

Overall, 21 patients formed the study group comprising 9 females and 12 males. Gender influenced the UAFH, LAFH, UPFH, ramus height, and gonial angle significantly. Males had higher values than females. Normal bite had an obtuse gonial angle than the deep bite, and the difference was statistically significant (
= 0.036). When the gonial angle was acute or square faced, the need for other surgical procedures was high and the difference was statistically significant (
= 00.048).

The results are discussed in the light of Indian skeletal anthropometry. selleckchem The relationship of the gonial angle with facial height parameters in bilateral MH cases in this part of the world is presented.

To compare the efficacy of intravenous (IV), intramassetric (IM) submucosal (SM) routes & oral routes of dexamethasone administration post impacted third molar removal surgery.

Prospective randomized comparative clinical study.

This prospective comparative study included 60 patients with Class II and position B type of impaction (according to Pell and Gregory's classification). Patients were randomly divided into 4 groups. Group A, B, C & D patients received 8mg dexamethasone immediately post-surgical tooth removal via the IV, SM and IM route & oral respectively. Assessment of swelling, mouth opening and pain was done at intervals of 1st, 3rd and 7th post-op days.

The average age of the patients was 27 years. The mean time taken was 20 mins 40 seconds. The IV group showed minimal swelling and better pain control on the 3rd post op day (statistically significant). All 4 routes showed comparable mouth opening results.

IV administration of dexamethasone post third molar surgery has been the traditional way because of its faster onset of action and increased efficacy; IM and SM routes are also comparably effective although oral route had the best patient acceptance.

Nasotracheal intubation is the most common method of airway management in oral and maxillofacial surgery patients. However, many times, it is associated with bleeding resulting from trauma to nasopharyngeal mucosa. We conducted this study to determine the effectiveness of nasopharyngeal airway (NPA) to easily facilitate the nasopharyngeal insertion and to reduce the trauma during nasotracheal intubation.

A total of 120 patients scheduled for elective oral and maxillofacial surgery requiring nasotracheal intubation were randomly divided into two groups of 60 each, after preparation with xylometazoline drops intranasally, lubrication with lignocaine jelly, and thermosoftening of the tip of the endotracheal tube (ETT). In group NPA, dilatation of the nasal cavity was done with NPA before nasotracheal intubation and in Group C, nasotracheal intubation was done without dilatation of the nasal cavity. The smoothness of insertion of ETT was graded on a 4‑point rating scale. Assessment of bleeding into nasopharynx was confirmed during laryngoscopy and was also graded with 4‑point scale.

In the NPA group, all the 60 (100%) patients had smooth or relatively smooth (Grade 0 or 1) insertion compared to 51 (85%) patients in the control group (
< 0.0001). Eighteen (30%) patients had mild (Grade 1) bleeding and one (1.67%) patient had moderate bleeding (Grade 2) in the control group, whereas only four (6.67%) patients in the NPA group had mild (Grade 1) bleeding (
= 0.0005).

Dilatation of nasal cavity with NPA significantly eases the insertion of ETT into the nasopharynx and also significantly decreases the incidence and severity of trauma and bleeding during nasotracheal intubation.

Augmentation of the maxillary sinus increases the lost height of ridge in the posterior maxilla. Bony convolutions from the floor of the sinus called septa may be encountered during the procedure and significantly impact the outcome of the procedure.

For this retrospective study, 120 cone-beam computed tomography (CBCT) scans were collected from the archives of the department of oral radiology in the time period between January 2016 and August 2018. Planmeca Romexis
software version 3.2.7 was used to check for the incidence, and then among the septa, plane of orientation, location with respect to the wall of the sinus, and in terms of relation to tooth were examined. The average height and average width of all the septa were measured using a measuring tool in the software.

Thirty-five of the total 88 patients showed septa in 40 sinuses, in which 36 sinuses showed one septum and 4 sinuses showed 2 septa. Forty-one septa were located on the floor of the sinus in the frontal orientation and 3 septa were located on the lateral wall of the sinus in the axial orientation. The mean height and mean width of the 41 septa on the floor of the sinus were 5.72 mm and 3.47 mm, respectively. The mean height of septa found on the lateral wall of the sinus was 5.59 mm.

Septa had a higher tendency to be in bucco-palatal direction and on the floor of the sinus and frequent occurrence in the region of molars. A thorough prediagnostic evaluation using CBCT is necessary prior to sinus augmentation procedures.

A thorough prediagnostic evaluation using CBCT is necessary prior to sinus augmentation procedures.The inherent proliferative capacity of the cystic lining of odontogenic keratocysts and tendency to recur with enucleation led to more aggressive management being widely recommended. Larger lesions preclude the possibility of resection. A case is reported in which extensive odontogenic keratocysts involve almost the entire mandibular medulla of a patient with basal cell nevus syndrome, illustrating the importance of customising treatment to accommodate the clinical and radiographic presentation of individual cases. The clinical outcome of using Carnoy's solution versus marsupialization is radiographically demonstrated in this case. Diagnostic criteria for basal cell nevus syndrome and treatment modalities of odontogenic keratocysts are discussed.
