Orthodontic extrusion of Ellis Class VIII fracture of maxillary lateral incisor - The sling shot method

A Bibliometric Study on the Top 101 Most-Cited Articles of Dental Journals of the Middle East/North Africa Countries From 2011 to 2021

Introduction: This retrospective descriptive study evaluated the Scopus-indexed dental journals and their most-cited documents affiliated with the Middle East and North Africa (MENA) countries from 2011 to 2021. Methods: Dental journals affiliated with MENA countries, their bibliometric indicators (SJR, CiteScore, SNIP, and H-index), and the 101 most cited articles of the considered journals were extracted and studied through descriptive statistics. In addition, the "citation per year" of each top 101 articles was calculated. Spearman's rho test was used for pairwise comparisons of the correlation coefficient values between each two of the considered bibliometric indicators. Results: The number of citations of the 101 most-cited papers ranged from 35 to 203. The mean (SD) citations of studied articles were 61.33 (37.58) and the median was 46. Furthermore, CiteScore had the highest significant correlation with SJR (r=0.828, P˂0.001). Moreover, the citation per year of the top 101 documents had no significant relationship with any of the journals' bibliometric indicators. Conclusion: Because journal performance and citation rate are multi-dimensional concepts, a single metric cannot express them thoroughly despite correlations between indices. "European Journal of Dentistry" from Turkey, "Saudi Dental Journal" from Saudi Arabia, and "Iranian Endodontic Journal" and "Journal of Lasers in Medical Sciences" both from Iran had the highest ranks in the SCImago portal and the highest scores in bibliometric indices amongst the MENA dental journals.

Dentist perspective on knowledge and practice toward Ellis class 3 tooth fracture: A survey

Traumatic dental injuries otherwise referred to as dental trauma is common in dental practice. The etiology of dental trauma is mostly falls and accidents in case of children and young adults. The treatment provided should be quick and effective which depends on the extent of the dental trauma, the injury might expose enamel, dentine and pulp of the affected teeth. Ellis class 3 involves all the 3 layers mentioned, so there should be quick measures taken. A survey was conducted among dental practitioners to assess their knowledge and practice experience about Ellis class 2 fracture. Detailed questionnaire was created with questions about Ellis class 3 tooth fracture and was circulated to 100 dental practitioners in Chennai, Tamilnadu through google forms. The collected data was analyzed using SPSS software. The knowledge and practice of Ellis class 3 trauma was 85%, the dental practitioners have adequate knowledge about the various clinical, diagnostic aids used and are aware to provide the correct treatment for each case. Based on the responses from the dental practitioners there is not much practice of Ellis class 3 dental trauma in their dental practice. Thus the present study concludes that the knowledge and practice of Ellis class 3 teeth fracture is good among dental practitioners and the various aspects are well known by dentists.

Association of crossbite with vertical skeletal growth patterns: A retrospective study

Crossbite is a type of malocclusion in which teeth are positioned more buccally or lingually than their corresponding opposing tooth in the upper or lower dental arch, resulting in a lateral mismatch of the teeth in the dental arches. Crossbite can be unilateral or bilateral, and it can be anterior or posterior. The link between crossbite and skeletal growth pattern remains uncertain. The current study aimed to find the prevalence of crossbite in subjects visiting a private dental hospital and evaluate if there is any association between crossbite and skeletal growth pattern. Data required for the study were procured from the dental information archiving software. The data were sorted and entered into an Excel spreadsheet. IBM SPSS software version 23 was used to conduct the statistical analysis. Graphs and tables were used to interpret the findings. the prevalence of crossbite was found to be 6.4%. Subjects with horizontal growth pattern commonly had crossbite, but no statistical significance (P = 0.07), standard deviation (1.011), was noted. There was no statistically significant association between different skeletal growth patterns however subjects with horizontal growth pattern reported more commonly with crossbite.

Association of vertical growth pattern with canine impactions in Dravidian subjects

Canine impaction, ectopic canines, canine transposition, canine transmigration, and agenesis are all caused by disturbances during development and eruption of the teeth. The position of the canines is of utmost importance, and they should be carefully inspected as they follow the longest path during eruption in the oral cavity and their shape and position play a major role in occlusal guidance. The prevalence of canine impaction may also be connected to the pattern of facial growth. The objective of this study was to analyze the association of vertical growth pattern and canine impaction in Dravidian population. The dental records were consulted for information. The patient information was gathered from the outpatient data records of patients who were treated with fixed orthodontic treatment at the private dental setup. Patients with canine impactions were shortlisted. Malocclusion, growth pattern, and type of impaction were recorded. The data obtained were tabulated and analyzed using statistical software. Out of 1385 subjects, 35 patients had impacted canines. Among 35 patients with impacted canines, 23 (65.71%) have a vertical growth pattern, 6 (17.14%) have an average growth pattern, and 6 (17.14%) have a horizontal growth pattern. According to the findings of this investigation, there was no gender-related difference in canine impaction. The canine impaction prevalence in Dravidian subjects was found to be 2.53%. Most of them with impacted canines had a vertical growth pattern.

Assessment of anterior open bite prevalence in children visiting a dental hospital - A retrospective evaluation

Anterior open bite (AOB) is the insufficient vertical overlapping between the maxillary and mandibular anteriors when the teeth are in centric occlusion. The purpose of this study was to determine the prevalence of AOB in children and adolescents who visited a private dental hospital. In this study, subjects aged between 16 and 18 years with AOB were included. Data about orthodontic examination of patients were taken from preentered dental records of the hospital. Data of patients with AOB regarding age, gender, and intraoral and extraoral features were collected from the case records of the subjects, and statistical analysis was performed (Chi-square test and nonparametric correlations). The prevalence percentage of open bite in the anteriors was 2.7%, with more prevalence in Class 1 subjects (81.5%). Subjects with AOB had competent lips (81.8%), straight nasolabial angle (86.8%), and shallow palatal vault (49.5%). AOB had no significant relationship with the type of malocclusion, palatal vault, and lip competency, according to the Chi-square test. AOB and the nasolabial angle had a significant association. Both acute and right-angled nasolabial angles were commonly seen in adolescent patients with AOB. In children and adolescents visiting a private dental hospital in Chennai, the prevalence of AOB was found to be 2.7%. A significant association was observed between AOB and nasolabial angle.

Association of severity of malocclusion with socioeconomic status in the South Indian population

Malocclusion has been linked to various factors out of which certain dietary patterns and unhealthy habits are the most overlooked. The dietary patterns and unhealthy habits vary according to socioeconomic status. The present research was aimed to perform an association of malocclusion severity with socioeconomic status. This study was done in a retrospective manner and was conducted at Saveetha Dental College. A total of 241 clinical case records of the participants with malocclusion reporting for orthodontic therapy were selected and enrolled for the study. Data on the socioeconomic status and the severity of malocclusion as assessed with the Index of Orthodontic Treatment Needs (IOTNs) index were noted. All these records were collected and entered into Excel and then analyzed through statistics. Descriptive statistics and nonparametric Chi-square tests were performed. From the analysis, the proportion of IOTN Grade 1 malocclusion (30%) was found to be the highest. The highest number of patients with Grade 1 malocclusion belonged to the lower socioeconomic class. Socioeconomic status and the severity of malocclusion were significantly associated with each other. Malocclusion prevalence and severity were more among participants belonging to lower socioeconomic groups.

Severity of mandibular arch crowding in different sagittal malocclusions

Mandibular anterior crowding is caused by a variety of factors. Mandibular incisor crowding can be caused by a number of causes including incisor and molar inclination, early loss of deciduous molars, mandibular growth, and oral musculature. The study was aimed to perform an association of the lower anterior crowding severity with gender and type of malocclusion. The current study was performed in a hospital setup and data about mandibular arch crowding patients were collected from the Records management system of a Private Dental Hospital in Chennai city. All the patient data on Mandibular arch crowding were sourced and tabulated after which statistical analysis with SPSS-IBM was done. Data collection was done over a period from June 2019 to February 2021. The entire study sample size was 634 case records. The result obtained from the statistical analysis was found that nearly 46% of the patients were found to have Mandibular arch crowding with female predilection (50%). The most commonly associated age groups were children than adults (63.2%) associated with mild type of crowding (65.1%). The most commonly involved malocclusion was found to be Class 1 (88.4%) Mild imbrications of the lower arch were common and were seen mainly in subjects with Class I malocclusion. Female subjects presented with more prevalence of mandibular arch crowding when compared to male subjects. Children were more affected by crowding than adults.

Variation in condylar morphology in different malocclusion among Indians

Temporo-mandibular joint (TMJ) joint and the condyle of mandible are observed in the radiographs of the skull and the jaw. Therefore, it is of interest to assess the predictability of four different shapes of condyle in skeletal class I, II and III malocclusion. The four commonly visualized shapes are oval, bird beak, diamond and crooked were assessed using an ortho pantomogram (OPG). Each of the malocclusion was visualized for different shapes of the condyle. 987 OPGs were radiographically evaluated and the morphology of 1974 condylar heads was visualized. The shapes of the condyles were grouped under four different types. Data shows that oval shaped condyle was most common followed by bird beak. There was variability in the diamond and crooked shape and was lesser than the other types. Thus, the shapes of the condyle are useful predictable guide in deciding the nature of the occlusion.

Palatal plane inclination on vertical growth pattern among Indians

The skeletal discrepancies in the vertical dimensions can either lead to a long face or a short face. The palatal plane inclination is one such contributing factor. The study sample comprised of 15 lateral cephalograms collected between the time period of June 2019 - March 2020 with 5 cephalograms belonging to skeletal Class I, II and III respectively. The inclination angle and mandibular plane angle were measured using the FACAD software. The obtained results were tabulated and statistically analysed using Pearson's correlation test to determine the correlation between the two variables. There was a statistically significant negative correlation between the skeletal malocclusions with a p value of 0.011. Thus, palatal plane inclination is not a major contributing factor for vertical growth pattern and it is suggestive of a multifactorial influence.
