Purpose For many dental patients, palatal injection proves to be a very traumatic experience. Diverse methods have been suggested to reduce the discomfort of palatal injection. Nevertheless, the reliability of these methods is not obviously evident and they are not found to be universally effective. The desirable method to evade pain during palatal injection is just not to have one. Hence, the present study aims at investigating if lidocaine hydrochloride could provide palatal anesthesia in maxilla when only a buccal infiltration anesthesia is done for teeth extraction. Patients and Methods One hundred and fifty patients requiring extraction of maxillary teeth were included in the study. Patients were randomly allotted to two groups, study and control. Patients in study group received a single buccal infiltration of 1.5 mL of lidocaine with epinephrine for extraction of maxillary teeth. Patients in control group received 1.5 mL of buccal and 0.3 mL of palatal infiltration of lidocaine with epinephrine for the extraction. After achieving adequate palatal anesthesia the tooth was extracted with consistent technique. Pain level experienced by the patients during injection procedure and during tooth extraction was rated in an 11-point pain rating scale. Time taken to achieve palatal anesthesia following a single buccal infiltration of anesthetic solution was evaluated by regular pin-prick evaluation of palatal tissues. Results The overall success rate of palatal anesthesia achieved with a single buccal infiltration is 81.3 %. The success rate reduced as we proceed from anterior to posterior maxilla. Time taken to achieve successful palatal anesthesia by single buccal infiltration is 7-9 min. Conclusion The extraction of permanent maxillary anterior teeth and premolars is possible by depositing local anesthesia to the buccal vestibule of the tooth without palatal supplementation. However, the extraction of permanent maxillary posterior teeth with similar technique would result in fewer success rates suggesting its avoidance.
Background:Age estimation is of prime importance in forensic science and clinical dentistry. Age estimation based on teeth development is one reliable approach. Many radiographic methods are proposed on the Western population for estimating dental age, and a similar assessment was found to be inadequate in Malaysian population. Hence, this study aims at formulating a regression model for dental age estimation in Malaysian children population using Cameriere's method.Materials and Methods:Orthopantomographs of 421 Malaysian children aged between 5 and 16 years involving all the three ethnic origins were digitalized and analyzed using Cameriere's method of age estimation. The subjects’ age was modeled as a function of the morphological variables, gender (g), ethnicity, sum of normalized open apices (s), number of tooth with completed root formation (N0) and the first-order interaction between s and N0.Results:The variables that contributed significantly to the fit were included in the regression model, yielding the following formula: Age = 11.368-0.345g + 0.553No -1.096s - 0.380s.No, where g is a variable, 1 for males and 2 for females. The equation explained 87.1% of total deviance.Conclusion:The results obtained insist on reframing the original Cameriere's formula to suit the population of the nation specifically. Further studies are to be conducted to evaluate the applicability of this formula on a larger sample size.
The easy availability and cost-effective nature of the materials, in concert with fast construction time, makes this suturing model appropriate when an affordable alternative is desired.
Goldenhar syndrome (oculo-auriculo-vertebral spectrum) is a rare congenital anomaly of unclear etiology and characterized by craniofacial anomalies such as hemifacial microsomia, auricular, ocular and vertebral anomalies. In many cases, this syndrome goes unnoticed due to a lack of knowledge about its features and because of its associated wide range of overlapping anomalies. Herewith, we present a case of Goldenhar syndrome in a 21-year-old male, who presented all the classical signs of this rare condition. This article also summarizes the characteristic features of patients with Goldenhar syndrome.
Introduction:In the undergraduate dental curriculum, student-to-student administration of first local anesthetic injection remains to be a traditional method in most of the dental institutions. This exercise is often foreseen by heterogeneous emotional responses both in student operator and respondent. Aim: This study evaluated the variations in attitude toward student-to-student LA administration and the associated anxiety levels among the genders. Materials and Methods: 40 female and 24 male preclinical dental students were provided with a questionnaire, containing statements of agreement. The experience and opinion throughout the procedure of first LA mandibular block administration was scored by the students using five-point Likert's scale and their anxiety levels were measured with 'interval scale of anxiety response' (ISAR) before, during and after administration of LA. The results were tested with Chi-Square test and Mann-Whitney test was used to know the significance of gender variation. Result: The perception of the operators as well as the recipient on mandibular anesthetic block injection analyzed by chi-square test showed significant values (P < 0.05) for all the statements. However, the gender variation performed by means of Mann-Whitney test demonstrated no significant statistical results. The anxiety evaluation using Mann-Whitney test showed significant variation among the genders both as an operator and respondent, except for the anxiety level of the operator after the injection procedure. Conclusion: This study illustrated the preparedness of the preclinical students for their first local anesthetic injections on humans and suggests for the required modification in the existing dental curriculum for a better training
