Objectives: Cleft lip and palate is a common congenital anomaly that impairs the aesthetics, speech, hearing, and psychological and social life of an individual. To achieve good aesthetic outcomes, presurgical nasoalveolar molding (NAM) has become important. Currently, the intraoral NAM technique is widely practiced. Numerous modifications have been made to intraoral NAM techniques, but the original problem of compliance leading to discontinuation of treatment remains unsolved. Therefore, the present study compared an extraoral NAM technique with the intraoral NAM technique. Materials and Methods: Twenty infants with complete unilateral cleft lip and palate were included and divided into two equal groups. Group A received the intraoral NAM technique, and Group B received the extraoral NAM technique. Pre- and postoperative extraoral and intraoral measurements were recorded. Results: Groups A and B did not differ significantly in any extraoral or intraoral parameter. Conclusion: The extraoral NAM technique is as effective as the intraoral NAM technique in achieving significant nasal and alveolar changes in complete unilateral cleft lip and palate patients. Additionally, it reduces the need for frequent hospital visits for activation and the stress associated with the insertion and removal of the intraoral NAM plate, thereby improving compliance.

Extraction of premolars for orthodontic purposes may prove challenging when the tooth is blocked or lingualised. The standard buccal approach may prove difficult in such cases. A novel technique was used for 16 patients with healthy linguoverted mandibular premolars using maxillary extraction forceps. The ease of extraction increased and resulted in uneventful postoperative healing in all patients. The authors suggest this as a preferred technique for extracting mandibular premolars in linguoversion.

Objectives : The purpose of this study was to examine students' difficulties in the process of oral radiography practice, to raise awareness of the importance and necessity of oral radiography and decipher, and to provide some information on effective ways of oral radiography practice. Methods : The subjects in this study were 285 dental hygiene students at K college, who included 153 sophomores and 132 graduates-to-be from June to November, 2010. Results : 1. The parts of the anatomy structure that they found it most difficult to decipher were maxillary molar(25.3%) and lower molar(22.1%). 2. They made during oral radiography was an improper film positioning(35.1%). 3. The part of bisecting technique was adjusting vertical and horizontal angles(53.0%). 4. The part of paralleling technique was positioning XCP in the oral cavity(44.2%). 5. The part of bite-wing technique was adjusting vertical and horizontal angles(38.2%). 6. The part of occlusion technique was positioning film and tube head(36.5%). 7. The part of panorama technique was finding out program setting(42.5%). Conclusions : The findings of the study indicated that in terms of anatomy structure decipher, it's especially difficult to decipher maxillary molar and lower molar, and that film positioning was difficult to do in the process of oral radiography. What difficulties they faced in applying each kind of oral radiography techniques and which part of the oral cavity they found it hard to radiograph were analyzed as well in this study. Given the findings of the study, more intensive practice is required to help students to acquire accurate oral radiography techniques to ensure their successful job performance in the future.

Objectives: Appropriate and accurate local anesthetic (LA) techniques are indispensable in the field of oral and maxillofacial surgery to obtain a satisfactory outcome for both the operating surgeon and the patient. When used alone, the inferior alveolar nerve block (IANB) technique requires supplemental injections like long buccal nerve block for extraction of mandibular molars leading to multiple traumatic experiences for the patient. The aim of this study was to anesthetize the inferior alveolar, lingual, and long buccal nerves with single-needle penetration requiring a minimal skillset such as administering a conventional IANB through introduction of the Benny Joseph technique for extraction of mandibular molars. Materials and Methods: This was a prospective study conducted in the Department of Oral and Maxillofacial Surgery, Kunhitharuvai Memorial Charitable Trust (KMCT) Dental College, Calicut, India. The duration of the study was 6 months, from June to November 2017, with a maximum sample size of 616 cases. The LA solution was 2% lignocaine with 1:100,000 adrenaline. The patients were selected from a population in the range of 20 to 40 years of age who reported to the outpatient department for routine dental extraction of normally positioned mandibular right or left first or second molars. Results: Of the 616 patients, 42 patients (6.8%) required re-anesthetization, a success rate of 93.2%. There were no complications such as hematoma formation, trismus, positive aspiration, and nerve injuries. None of the cases required re-anesthetization in the perioperative period. Conclusion: The Benny Joseph technique can be employed and is effective compared with conventional IANB techniques by reducing trauma to the patient and also requires less technique sensitivity.

Background: Behavior guidance is a technique used to subdue inappropriate behavior by establishing communication that meets the needs of a child. This study aimed to measure the effectiveness of a mobile app (Little Lovely Dentist) compared to the tell-show-do (TSD) technique in managing anxious children during their first dental visit. Methods: Fifty children (30 boys and 20 girls) without any past dental experience, aged from 7 to 11 years, were randomly allocated into either the dental app group or the TSD group. The pre- and post-operative anxiety of children who underwent prophylactic cleaning was assessed both physiologically and subjectively using a heart rate measurement and the RMS pictorial scale, respectively. Results: The intragroup comparison of heart rate and RMS scores for children allocated to the dental app group was statistically significant (P value ≤ 0.001). However, a significant reduction only occurred in the RMS scores, but not the heart rate measurements, in the TSD group. Conversely, there was an increase in heart rates in the TSD group. Conclusion: Educating the child prior to a dental procedure using a smartphone application such as Little Lovely Dentist can significantly alleviate the anticipatory anxiety and engage children in dental treatment during their first visit.

Mandibular implant overdenture is a good treatment option for complete edentulous patients with restoring removable prosthesis. Mandibular implant overdenture with two implants and locator attachments is widely used. It is tissue-supported overdenture that is made with the concept of conventional complete denture fabrication. There are two patients who provided impressions by open mouth technique and closed mouth technique in each case. In both cases, mandibular implant overdentures were restored with functionally and aesthetically satisfying results.

Many approaches to local anesthesia have been studied in dentistry. In this study, we introduce a new local anesthetic method, "Point-Inject Technique (PIT)", and compare it with traditional injection techniques. The PIT method utilizes both the vasoconstrictive and antinociceptive properties of local anesthetics as well as the application of controlled pressure during injection, reducing the time to complete anesthesia. Fifty patients were selected as the experimental group who were anesthetized using PIT, and the other 50 patients were selected as the control group using the direct injection method with a carpool syringe. The PIT group received 0.25 cartridges of 2% lidocaine with 1:100,000 epinephrine. The control group received 1.5~2 cartridges of 2% lidocaine with 1:100,000 epinephrine. Both groups were asked to mark the intensity of the pain caused by anesthesia using the Numeric Pain Rating Scale. The average time to recover from anesthesia was 40 minutes in the experimental group and 90 minutes in the control group. Additionally, 96% of the experimental group reported feeling no pain, while 78% of the control group reported having some form of pain during injection. The PIT method reduced both the reported pain scores of patients as well as time to recover from local anesthesia than the widely-used syringe injection method.
