Objective: To determine the relationship between skeletal malocclusion and upper pharyngeal airway space in the United Arab Emirates population using linear cephalometric measurements. Material and Methods: A retrospective cross-sectional study was performed on lateral cephalogram radiographs acquired from the University Dental Hospital. Through convenience sampling, 70 lateral cephalograms were selected from 200, meeting the inclusion criteria for this study. Study subjects were divided into three groups: Class I (n=25), Class II (n=21), and Class III (n=24). The study groups were compared based on the linear upper pharyngeal airway space measurements. Results: The three groups observed significant differences between the upper pharyngeal airway measurements. No differences in parameters were noted within the male and female study subjects. A highly significant difference (p

IntroductionCoronectomy is a safer option than extraction for third molars with an increased risk of injury to the inferior alveolar nerve. However, it can still cause complications due to a lack of standardized and effective tooth sectioning techniques. We proposed a standardized protocol for third molar coronectomy involving standardized tooth sectioning parameters to minimize potential complications, surgical failure, and the need for further procedures.MethodsThe study was conducted on 69 eligible archived CBCTs. The coronal sections of the mandibular at the anterior-most level of the lower third molar were used to determine various axes and reference points. This was done to establish the target angle and depth for the coronectomy sectioning. The data on the depth and angle of the sectioning was presented in means and standard deviation. A multivariate analysis of variance was used to determine the impact of study variables on drill depth and angle. Linear regression and correlation between study variables were also used to predict the drill depth and angle.ResultsThe samples included 46 males and 23 females aged from 21 to 47 years. The mean drill angle was determined as 25.01 ± 3.28. The mean drill depth was 9.60 ± 9.90 mm. The bucco-lingual tilt had a significant effect on the drill depth, F(1, 62) = 5.15, p < 0.05, but no significant impact on the drill angle, F(1, 62) = 29.62, p > 0.05. The study results suggest that a standardized sectioning protocol can be effective during surgical coronectomy procedures.DiscussionDrilling at a 25-degree angle to a depth of 9.5 mm is advisable to obtain the desired results. This approach will ensure no remaining enamel is left, minimize the chances of root extrusion and future eruption, and improve the outcome.

Abstract The prevalence of gingivitis is substantial within the general population, necessitating rigorous oral hygiene maintenance. Objective This study assessed a Garcinia indica (GI) fruit extract-based mouthrinse, comparing it to a 0.1% turmeric mouthrinse and a 0.2% Chlorhexidine (CHX) mouthrinse. The evaluation encompassed substantivity, staining potential, antimicrobial efficacy and cytocompatibility. Methodology The study employed 182 tooth sections. For antimicrobial analysis, 64 extracted human teeth coated with a polymicrobial biofilm were divided into four groups, each receiving an experimental mouthrinse or serving as a control group with distilled water. Microbial reduction was assessed through colony forming units (CFU). Substantivity was evaluated on 54 human tooth sections using a UV spectrophotometer, while staining potential was examined on 64 tooth sections. Cytocompatibility was tested using colorimetric assay to determine non-toxic levels of 0.2% GI fruit extract, 0.1% Turmeric, and 0.2% CHX. Results Data were analysed with one-way ANOVA (α=0.05). Cell viability was highly significant (p0.05) at end of 12 hours. However, 0.1% Turmeric showed minimal CFU reduction (P

Abstract Background Fully guided implant surgery as a technique is gaining popularity. It has been observed that use of surgical guides improves precision and predictability for dental implant placement. However, like any other newer technology, the acceptance of fully guided dental implant technology among users is based upon its perceived usability. This study aimed at evaluating the perception about using Virtual Implant Planning Software (VIPS) among undergraduate dental students at the university of Sharjah. Methods Ninety-Six dental surgery students from the University of Sharjah were included in the study. One week after the Virtual Implant Planning Software (Planmeca Romexis version 6.2 procedure, students were asked to complete a Combined technology acceptance model and the theory of planned behaviour (C-TAM TPB) questionnaire. Sixty-six students responded to the questionnaire. Results Cronbach’s alpha surpassed 0.7 for perceived usefulness, perceived ease of use, perceived behavioral control, and subjective norm. Attitude and behavioural intention reported Cronbach’s alpha values less than 0.7. Spearman’s correlation coefficient was significant for all the constructs. Perceived ease of use explained 49%, 33%, and 42% of the variance of perceived usefulness (R2 = 0.49), attitude (R2 = 0.33), and perceived behavioral control (R2 = 0.42) respectively. Perceived usefulness explained 25%, 18%, and 23% of the variance of attitude (R2 = 0.25), behavioral intention (R2 = 0.18), and perceived behavioral control (R2 = 0.23) respectively. Attitude accounted for 25%, 33%, and 29% of the variance of behavioral intention (R2 = 0.25), perceived behavioral control (R = 0.33), and subjective norm (R = 0.29) respectively. Conclusion The fully guided VIPS was acceptable by dental students specifically because of its usability. This makes VIPS a very effective tool for teaching implantology for dental students. VIPS also allows students to perform multiple repetitions of the implant planning procedure which enhances understanding and content retention.

Background: The search for effective antimicrobial agents to mitigate peri-implant infections remains a crucial aspect of implant dentistry. This study aimed to evaluate and compare the antimicrobial efficacy of i-PRF, A-PRF+, and enamel matrix derivative (EMD) on decontaminated rough and smooth titanium (Ti) discs. Materials and Methods: Rough and smooth Ti discs were coated with multispecies biofilm and thoroughly debrided using a chitosan-bristled brush. Subsequently, i-PRF, A-PRF+, and EMD were applied. Untreated discs served as control. Residual adherent bacteria present on the treated Ti discs were visualized by SEM and quantified using culture technique, and colony-forming units (CFUs) were measured after 48 h and 7 days. Results: i-PRF demonstrated better antimicrobial effectiveness on both smooth and rough implant surfaces as compared to A-PRF+ and EMD (p < 0.001). In all the experimental groups, smooth Ti discs displayed a greater reduction in microbes compared to rough Ti discs when treated with the biologics. The major reduction in CFU values was determined after seven days. Conclusions: i-PRF as a regenerative material may also be suitable for decontaminating implant surfaces, which could influence tissue healing and regenerative outcomes positively.

Background: The complex nature of maxillofacial injuries can affect the surgical treatment outcomes and general well-being of the patient. To evaluate the efficiency of the surgical treatment, assessment of the quality of life (QOL) of the patients is of vital importance. Due to the absence of an exclusive QOL assessment tool for maxillofacial fractures, we introduce the ‘Twenty-point quality of life assessment in facial trauma patients in Indian population'. The aim of this study was to assess and evaluate the QOL following surgical management of maxillofacial trauma patients based on the severity of the injury. Methods: The study consisted of 182 subjects divided into two groups of 91 each (Group A: severe facial injury and Group B: mild to moderate facial injury). The Facial Injury Severity Scale (FISS) was used to determine the severity of facial fractures and injuries. The twenty–point quality of life assessment tool includes Zone 1 (Psychosocial impact) and Zone 2 (Functional and aesthetic impact), with ten domains each to assess QOL. Results: In Zone 1, the mean scores for Group A and Group B were 38.6 and 39.26, respectively. In Zone 2, Group B (44.56) had higher mean scores compared to Group A (32.92) (p< 0.001). Group B (83.8) had higher mean scores compared to Group A (71.58) when the total of both Zone 1 and Zone 2 were taken into consideration (p

Objectives: The aim of this study was to analyse volumetric asymmetries between the right and left condyles in relation to age, gender, and dental status. Materials and methods: A retrospective analysis of 150 cone beam computed tomography (CBCT) scans was conducted. A single investigator performed the volumetric analysis of the CBCT scans using Vesalius 3D software. The volumetric data were analysed in relation to the gender, age, and dental status. Results: The mean right condylar volume was significantly higher (P < .01) than the left condylar volume. Right and left condylar volumes were significantly higher (P < .01) in male study participants when compared to female study participants. There was no significant difference (P = .47) in the volumetric asymmetry between the male and female study participants. The volumetric asymmetry was significantly higher (P < .01) in the older age groups when compared to the younger age groups. The volumetric asymmetry was significantly higher (P < .01) in the partially and completely edentulous patients when compared to the dentate study participants. The condylar volume on the side having a partially edentulous area was significantly lower than the condylar volume of the contralateral dentate side (P < .001). Conclusions: The volumetric asymmetry between the right and left condyle significantly increases with age and edentulousness. The result of the study encourages the clinicians to perform volumetric evaluation of the condyles in cases of radiographically evident condylar asymmetries to obtain a more accurate diagnosis.

Background: Dermatoglyphics is the study of various dermal configurations on the fingers, palms, and soles. These appear during the 12th week of intrauterine life and develop completely by the 24th week. It is said that they remain constant thereafter. The aim of the present study was to compare and assess the association of dermatoglyphic patterns between skeletal class I and skeletal class III malocclusion. Methods: Finger and palm prints were collected using the ink and roller method from 604 subjects who were divided into skeletal class I, class III with maxillary retrognathism and class III with mandibular prognathism based on lateral cephalogram assessment. Results: Loop pattern was more predominant in skeletal class I malocclusion subjects (72.1%) and whorl pattern was more frequent in the other two groups (group II=70.1% and group III=69.3%). Total finger ridge count (TFRC) and atd (digital triradius ‘a’- axial triradius ‘t’- digital triradius ‘d’) angle also showed significant difference between the study groups. Conclusions: The present study attempted in assessing the association between dermatoglyphic patterns and skeletal malocclusion. Analysing dermal configurations may aid in indicating the type of developing malocclusion and thus help in interceptive and preventive orthodontics.

Objective: The use of tobacco has proven to be one of the leading cause of preventable premature deaths and diseases across the globe. The World Health Organization (WHO) claims that tobacco consumption alone kills more people annually as compared to Acquired Immunodeficiency Syndrome (AIDS), alcohol, and other addictions (drugs, etc.) put together. Although the Cigarettes and Other Tobacco Products Act (COTPA) is a powerful Indian national law to curb the tobacco epidemic, the effectiveness of its implementation remains disputed. The current study aims to examine the role of the security guards in the implementation of the COTPA by assessing their awareness. Method: A cross-sectional questionnaire-based study was conducted among 258 security guards in Goa to ascertain the knowledge regarding the tobacco legislation in the country. A self-administered 20-item close-ended questionnaire was used to collect information regarding the demographic variables, tobacco use, and knowledge regarding COTPA. Data analysis was done using SPSS version 22.0. Results: The mean age of the study participants was 29.93 ± 6.93 years. Overall, 68.6% of the study participants were aware of any tobacco control law in India. It was observed that 71% of the subjects had adequate knowledge of the COTPA. The participants with higher secondary educational levels had significantly higher knowledge scores. Conclusion: The overall awareness of the security guard was good but there is a need to provide in-depth knowledge on certain key aspects of the COTPA. Efforts should be made to train the security personnel to increase their awareness of the act.

Introduction: Screening programs with the use of specific diagnostic tools in asymptomatic patients are useful in identifying suspicious oral lesions and aid in the early diagnosis of oral cancer. The objective of the present study was to compare the oral rub and rinse technique with the conventional exfoliative cytology in the screening of oral malignant and potentially malignant diseases. Materials and Methods: An oral cancer screening program was conducted in the Dakshina Kannada district of Karnataka, India. The oral rub and rinse technique was performed on patients who had red/white lesions in the oral mucosa followed by the conventional exfoliative cytology. Scalpel biopsy was performed to confirm for presence or absence of malignancy in cases wherever indicated. Descriptive statistics (frequency and percentage) were used in the present study. Results: A total of 848 subjects were screened for oral cancer and precancer. About 112 participants had premalignant/malignant lesions and biopsy was performed on 30 subjects. Of these, 27.7% were Class I smears, 39.3% were Class II smears, 22.3% were Class III smears, 4.5% were Class IV smears, and 6.2% were unsatisfactory using the conventional technique, whereas the oral rub and rinse technique showed 26.8% Class I smears, 42.9% Class II smears, 19.6% Class III smears, 6.2% Class IV smears, 0.9% Class V smears, and 3.6% unsatisfactory. Conclusion: Although both the techniques could detect malignancy, the oral rub and rinse technique showed better cellular clarity and sample adequacy when compared to conventional exfoliative cytology, which makes it a practical tool in resource-challenged settings.

Background The association of the linear dimensions of the inferior turbinate hypertrophy with nasal septal deviation has been studied recently. However, the volumetric dimensions provide a more accurate status of the turbinate hypertrophy compared to linear measurements. The aim of this study was to analyze the association of inferior nasal turbinate volume with the degree of nasal septal deviation (NSD). Methods A retrospective evaluation of the cone beam computed tomography (CBCT) scans of 412 patients was carried out to obtain 150 scans which were included in the study. The scans were categorized into three groups. Group 1 comprised of 50 scans of patients with no inferior turbinate hypertrophy (ITH) and no nasal septal deviation. Group 2 comprised of 50 scans of patients with ITH and no NSD; whereas Group 3 included 50 scans of patients with ITH and NSD. The total turbinate volume of inferior turbinates (bilateral) were determined by using Vesalius 3D software (PS-Medtech, Amsterdam, Netherlands). Results The intraclass correlation coefficient (ICC) between the volumetric estimations performed by the two radiologists was 0.82. There were no significant age and gender related changes in the total turbinate volume. Patients in Group 3 had significantly higher (p = 0.001) total turbinate volume compared to Group 2 and Group 1. There was a positive and significant correlation (r = 0.52, p = 0.002) between the degree of septal deviation and total turbinate volume. When the total turbinate volume of the patients with different types of septal deviation was compared in Group 3, a statistically significant difference (p = 0.001) was observed. Regression analysis revealed that the septal deviation angle (SDA) (p = 0.001) had a relationship with total turbinate volume. From the results of the study we can conclude that the total turbinate volume is higher in patients with nasal septal deviation. It can also be concluded that the septal deviation angle has a positive correlation with total turbinate volume. The data obtained from the study can be useful in post-surgical follow up and evaluation of patients with nasal septal deviation and hypertrophied inferior nasal turbinate.

Objectives: The volume of the inferior turbinates (IT) and the lining of the maxillary sinuses are important parameters when assessing sino-nasal diseases. However, no radiographic studies have investigated the correlation between these parameters. The present study was conducted to analyze the association between IT volumes and thickness of maxillary sinus mucosal lining. Materials and methods: A retrospective evaluation of the cone-beam computed tomography (CBCT) scans of 100 adult subjects was carried out by two radiologists. The scans were assigned to two groups (Group 1 & 2) based on the radiographic evidence of maxillary sinus lining in the CBCT scans. Group 1 consisted of 50 CBCT scans of subjects with no evidence of maxillary sinus mucosal lining, whereas Group 2 consisted of 50 subjects with evidence of maxillary sinus mucosal lining. The scans in the Group 2 were further sub-classified into five categories, based on the thickness of the maxillary sinus mucosal lining. Vesalius 3D software was used to evaluate the total volume of inferior nasal turbinates by the two radiologists and a mean volume was obtained for each study subject. Results: The intraclass correlation coefficient (ICC) between the volumetric estimations performed by the two radiologist was 0.87. Analysis of the results revealed that there was no significant gender-based difference (Group 1, P = 0.67 and Group 2, P = 0.95) in the total turbinate volume in either of the study groups. The total turbinate volume did not show any significant correlation (Group 1, r = 0.24 and Group 2, r = 0.12) with the age. There was a significant increase (P = 0.001) in the total turbinate volume of the subjects in Group 2 compared to Group 1. Regression analysis revealed that the thickness of sinus lining correlated significantly (P = 0.001) with the total turbinate volume. Conclusion: An increase in the total turbinate volume has been associated with an increase in the thickness of the maxillary sinus mucosal lining. The data from this study will be useful for post-operative follow-up of inferior turbinates and maxillary sinus lining after the turbinate volume reduction procedures.
