Evaluation Of Nasopalatine Canal Using Cone Beam Computed Tomography – A Retrospective Study

Background:Implantology is a very significant branch of dentistry that deals with the rehabilitation of edentulous patients. Thus, knowledge of anatomical variations of related neurovascular structures such as the nasopalatine canal is essential. Aim:The aim of study was to determine the form, length, and diameter of the nasopalatine canal using CBCT. Materials and Methods:In this retrospective study, images were archived from CBCTunit and visualized using Romexis software. The nasopalatine canals of 50 patients between the age range of 18-59years were analyzed. The shape of the nasopalatine canal, length of the nasopalatine canal and the diameter of incisive foramen were assessed in sagittal and coronal section. The width of labial and palatal alveolar bone around the canal and inclination of the nasopalatine canal to hard palate were evaluated. Statistics: (1) if there is any relation between the gender and the assessed parameters (2) if there is any relation between edentulous and partially edentulous patients with the assessed parameters.Results:The most common shape of the nasopalatine canal was cylindrical. The average length of the nasopalatine canal was 12.14±2.41 mm and the average diameter of incisive foramen 3.45±0.84 mm anteroposteriorly and 3.77±0.94mm mediolaterally. The average inclination of the nasopalatine canal to hard palate was 119.93±9.73°Conclusion:This study highlights the variations seen in the nasopalatine canal. The close vicinity of nasopalatine canal and implant can lead to sensory disturbances and damage of the tissues. Thus, a thorough knowledge before the surgical - implant procedure using cone beam computed tomography seems beneficial.

Subcutaneous emphysema and pneumomediastinum during dental treatment

Subcutaneous emphysema is a rare complication of maxillofacial and dental surgery, and may be life-threatening because it can rapidly spread to the scalp, neck, and chest. We report a case of severe subcutaneous emphysema with pneumomediastinum during restorative dentistry in a child with difficulty in communication. The patient was hospitalized for conservative treatment and discharged after complete recovery as a result of timely diagnosis and treatment. Dentists and pediatricians should be aware of potential subcutaneous emphysema during dental treatment, with careful monitoring to ensure prompt diagnosis and treatment.

Application of Hand Towel Drape over Dingman Mouth Gag

In cleft palate surgery, the environment is especially critical when suturing. Encum-bered, obstructive space in the environment can hinder a suture while using the Dingman mouth gag. We introduced a novel but simple draping technique. A simple hand towel is placed over the gag. A hole is cut out in the middle according to each patient's mouth. After making the hole, the hand towel is soaked in water and gently squeezed. Then the towel is properly placed over the Dingman mouth gag. Dripping water on the hand towel during the suture helps keep it in place. Using this draping technique, we cut 14 minutes of operation time compared to the average operation time of the past 2 years. There were several disadvantages in previous draping method. First, long suture material may easily get caught. Second, the operation field can easily be contaminated. Third, focusing on the operation becomes difficult due to the obstruction. This draping technique can compensate for the disadvantages of the previous Dingman mouth gag.

Glucocorticoides como profiláctico antinflamatorio en cirugía de terceras molares inferiores / Glucocorticoids as a prophylactic anti-inflammatory in inferior third molar surgery

Objetivo: Comparar la presencia de inflamación aguda severa en pacientes con y sin medicación antes del procedimiento de exodoncia de terceros molares inferiores, atendidos en la Clínica Odontológica de la Universidad Nacional Federico Villarreal. Material y métodos: Se tomó como muestra 116 pacientes de ambos sexos, entre 21 y 45 años de edad los cuales fueron divididos en dos grupos aleatoriamente, solo uno recibió medicación con Glucocorticoides antes del tratamiento. Resultados: Se encontró que el 92% de pacientes del grupo que no recibió medicación previa presentaron dolor agudo durante las primeras 48 horas, medicándose con fármacos no narcóticos (78%) y fármacos narcóticos (22%); as¡ mismo, presentaron signos de edema y trismus (82% y 80%) permaneciendo hasta los 6 d¡as, contrariamente los pacientes que recibieron medicación previa al tratamiento, presentaron signos y s¡ntomas de dolor agudo, edema y trismus en el 12%, 4% y 2% respectivamente, requiriendo de medicación solo 15% y con fármacos no narcóticos, encontrando asociaci¢n entre la medicación y frecuencia de signos, s¡ntomas y consumo de fármacos (p<0,05). El promedio de fármaco ingeridos por el grupo que no recibió medicación fue de 24 tabletas (3 analgésicos, 1 anti inflamatorio por d¡a durante 6 d¡as), mientras que, los que recibieron medicación ingirieron en promedio 6 tabletas y en su totalidad analgésicos. La apertura bucal máxima, signo del trismus, en los pacientes que no recibieron medicación fue en promedio 12mm y en los que recibieron medicación 32mm, siendo esta diferencia estad¡sticamente significativa (p<0,05). Conclusión: La presencia de signos y s¡ntomas de inflamación aguda severa as¡ como el consumo de fármacos fue mayor en el grupo que no recibió medicación con glucocorticoides antes de la intervención.

Objective: Compare the presence of severe acute inflammation in patients with and without medication before the procedure of extraction of third molars, treated at the Dental Clinic of Universidad Nacional Federico Villarreal. Material and Methods: Sample was taken as 116 patients of both sexes, between 21 and 45 years who were randomly divided into two groups, only one received medication before treatment with glucocorticoid. Results: It was found that 92% of patients who did not receive premedication had severe pain during the first 48 hours, medicating with non-narcotic drugs (78%) and narcotic drugs (22%), likewise, showed signs of edema and trismus (82% and 80%) 6 days remaining until contrary the patients who received pre-treatment medication, had signs and symptoms of acute pain, edema and trismus at 12%, 4% and 2% respectively, requiring only medication 15%, and non-narcotic drugs, finding association between medication and frequency of signs, symptoms, and medication (p <.05). The average drug ingested by the group that received no medication was 24 tablets (3 analgesics, anti-inflammatory one per day for 6 days), while those receiving medication ingested an average of 6 tablets and painkillers entirely. The maximum mouth opening, sign trismus in patients who received no medication was on average 12mm and 32mm those receiving medication, and this difference was statistically significant (p <0.05). Conclusions: The presence of signs and symptoms of acute inflammation and severe drug consumption was higher in the group not receiving glucocorticoid medication before surgery.

Transoral Removal of Submandibular Stone / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Traditionally, the treatment of choice for submandibular calculi that lie in the proximal duct or gland parenchyme has been sialadenectomy despite its risk. Recently, minimally invasive techniques including lithotripsy, sialendoscope have been reported, although these techniques have some limitations on large, infected calculi. The aim of this present review is to assess the transoral removal of submandibular calculi. SUBJECTS AND METHOD: The records of a hundred and sixty-three patients who underwent transoral removal of submandibular calculi between January 1, 1995 and July 31, 2004 were retrospectively reviewed. RESULTS: The complete removal of calculi was observed in 147 (90.2%) patients, partial removal with residual calculi in 8 (4.9%) patients and failure of removal in 8 (4.9%) patients. The removal rate of palpable calculi was significantly high. The removal rate of anterior, infection-free calculi was higher than the posterior and infected calculi, but there was no statistical significance. The size of calculi was not related with the removal rate of calculi. A hundred fifty-two (93.3%) of 155 patients in whom some or all of calculi were removed were free of symptoms of calculi. Symptoms were recurred in 19 patients after 2-68 (median 24) months and in 13 patients calculi were removed transorally again. CONCLUSION: The transoral removal of calculi is useful in preservation of the submandibular gland and effective in palpable calculi regardless of location, size, and combined infection.
