Emotional intelligence and perceived stress among female dental students at King Khalid University, Saudi Arabia.

OBJECTIVE: To assess the emotional intelligence and identify the perceived sources of stress among female dental students and interns at King Khalid University College of Dentistry (KKUCOD), to investigate whether specific stressors were related to the year of study and gender, and to evaluate the relationship between emotional intelligence (EI) and perceived stress (PS). MATERIALS AND METHODS: Total of 150 female undergraduates from 5th and 6th years and dental interns were invited to complete a questionnaire using face-to-face interview. Data on EI was collected using a scale developed by Schutte et al. while a modified version of the Dental Environment Stress (DES) was applied to assess the stress perceived by dental students. RESULTS: 120 students agreed to join the study with a response rate of 84%. Mean EI score for the sample was 120 (SD = 11.56), and the mean PS score was 70.37 (SD = 16.19). One-way ANOVA revealed a significant difference between different age groups and the educational, environmental score (P < 0.05). Correlational analysis showed that the PS scale and its factors correlated positively with each other (P < 0.01) and directly with the total EI score (P > 0.01); except for the living accommodation factor, negative correlations with overall EI score were significant. CONCLUSION: The present study showed that female interns and undergraduate students in clinical years of study at College of Dentistry reported higher EI and PS. The educational environmental score was found to be significantly different among different age groups. In contrary to most published literature, a direct association between EI and PS scores was found, except for the living accommodation factor. This might be attributed to the fact that the study was conducted 1 month prior to final exams. Living accommodation, personal factors, educational environment, academic work and clinical factors were identified as significant predictors of PS.

Development of artificial neural network model for prediction of post-streptococcus mutans in dental caries.

BACKGROUND AND OBJECTIVE: Streptococcus mutans is the primary initiator and most common organism associated with dental caries. Prediction of post-Streptococcus mutans favours in the selection of appropriate caries excavation method which eventually results in meliorate caries-free cavity preparation for restoration. The objective of this study is to predict the post-Streptococcus mutans prior to dental caries excavation based on pre- Streptococcus mutans using iOS App developed on Artificial Neural Network (ANN) model. METHODS: For the current research work, children with occlusal dentinal caries lesion were chosen, 45 primary molar teeth cases were studied. Caries excavation was done with carbide bur, polymer bur and spoon excavator. The colony forming units for pre and post-Streptococcus mutans were recorded, data emanating from clinical trials was employed to develop the ANN models. ANN models were trained, validated and tested with the registered clinical data using different ANN architectures. RESULTS: Feedforward backpropagation ANN model with an architecture of 4-5-1, predicts post-Streptococcus mutans with an efficiency of 0.99033, mean squared error and mean absolute percentage error for testing cases were 0.2341 and 4.967 respectively. CONCLUSIONS: Caries excavation methods and pre-Streptococcus mutans are feed as inputs, while post-Streptococcus mutans as targets to develop ANN model. Based on the developed ANN model, an ingenious iOS App was developed, the global clinician may utilize the App to meticulously predict post-Streptococcus mutans on iPhone based on pre-Streptococcus mutans, which in turn aids in decision making for the selection of caries excavation method. This study manifests the potential application of iOS App with built-in ANN model in efficiently predicting the post-Streptococcus mutans. Also, the study extends scope for applications of iOS App with built-in ANN models in clinical medicine.

Oral Habits: Prevalence and Effects on Occlusion Among 7 to 13 Years Old School Children in Aseer, Saudi Arabia

Abstract Objective: To evaluate the prevalence of deleterious oral habits and its effect on occlusion in school going children from 7 to 13 years old, in Aseer region of Saudi Arabia. Material and Methods: A cross-sectional study was conducted by clinical examination for the total sample of 750, who were attending private/ government schools in Aseer region school. Students were selected by stratified cluster random sampling. Clinical findings of each oral habits, including assessment of malocclusion, were examined involving the following parameters, i.e., crowding, spacing, open bite, crossbite and deep bite. Logistic regression analysis was conducted. Results: Boys had 26.2 % of crowded teeth, while 16.3% of girls were found to have crowded teeth; the difference was found to be significant (p=0.002). Spacing was present in 26.4% of boys and 16.7% girls; a significant difference was found between the two (p=0.002). Sleep bruxism was observed more among male subjects than females with a statistically significant difference in detrimental habits (p<0.001). Those subjects having tongue thrusting are 1.264 times at more risk of having crowded teeth than those with no tongue thrusting. Conclusion: There was a high prevalence of malocclusion associated with harmful oral habits in children. This highlighted the need to implement programs of oral care and health education for preventive orthodontic treatment at an early age.

Clinical Evaluation of Solitary Median Maxillary Central Incisor Syndrome.

Solitary median maxillary central incisor (SMMCI) is a rare dental anomaly. It is estimated to occur in 1 : 50,000 live births. The SMMCI tooth differs from the normal central incisor in that the crown form is symmetric and it develops and erupts precisely in the midline of the maxillary dental arch in both primary and permanent dentitions. The presence of SMMCI with hemifacial microsomia (HFM) is a very rare clinical condition. We report a case of SMMCI in a female of African ethnic origin, who presented with SMMCI in permanent dentition with mild nasal stenosis. An early diagnosis of SMMCI is important, since it may be a sign for other severe congenital or developmental abnormalities. Therefore, systematic follow-up and close monitoring of the growth and development of SMMCI patients are crucial.

Comparison of mesiodistal tooth width in individuals from three ethnic groups in Southern Saudi Arabia.

OBJECTIVE: The aim of this study was to compare the mesiodistal tooth sizes and to see the gender dimorphism among three ethnic groups of southern part of Saudi Arabia, that is, Asir, Najran, and Jizan region. SUBJECTS AND METHODS: The sample composed of 90 individuals (45 of each gender) from 3 different regions of southern Saudi Arabia, having mean age of 26.9 years. The measurements were done directly on the models with the aid of the digital calliper measuring the largest mesiodistal measure of incisors, canines, premolars, and molars in both sides. RESULTS: Almost all the mesiodistal tooth widths were statistically significant between the groups except maxillary and mandibular permanent third molars. Regarding sexual dimorphism, the groups were combined; almost all the mesiodistal tooth widths were not shown statistically significant difference between the males and females except that right first permanent premolars were significantly larger in the females than in the males. CONCLUSION: The present study has provided norms of the mesiodistal permanent tooth diameters of a Saudi population that are newer and more complete than the previously published norms. There appear to be some secular trends in the mesiodistal diameter of the Saudi permanent teeth toward sexual dimorphism.

Oral hygiene practice and periodontal status among two tribal population of Telangana state, India- an epidemiological study.

BACKGROUND: The tribes of India have poor periodontal health status due to their isolation, awareness and less accessibility to dental resources. They follow traditional methods of oral hygiene practice, which are found to be inadequate and inaccurate to maintain their good oral health. This study aims to assess the oral hygiene practice, oral hygiene and periodontal status of two tribes residing in Bhadrachalam, Telangana, India. METHODS: Based on accessibility the two tribes Koya and Lambada were included in the study. The total study population consisted of 1000 subjects, with 500 subjects in each group. Using a preformed proforma the oral hygiene practices were recorded for two groups and oral examination was done using Oral Hygiene Index (OHI-S) index and Community Periodontal Index (CPI). RESULTS: The OHI-S ranged between 2.5-3.0 in both the groups. The CPI index scores showed that sextants with calculus, shallow pockets, deep pockets and loss of attachment of 4-5 mm were significantly present in both groups. CONCLUSION: To conclude, though practice of poor oral hygiene and compromised periodontal status was seen among both groups. However, it was more prevalent in Koya. Under these circumstances, implementation of a basic awareness of oral health care programme for these tribes should be a high priority.

Nifedipine induced gingival enlargement in an edentulous patient: a case report with one year follow up.

BACKGROUND: Gingival enlargement due to calcium channel blockers is a common complaint reported by patients. It can be localized or generalized and can range from mild to severe, affecting patients appearance and function. Nifedipine induced gingival enlargement is noticed only in 10 % of patients and very few cases of Nifedipine induced gingival enlargement in an edentulous patient have been documented in the literature. CASE PRESENTATION: Here in, we report a case of gingival enlargement in a 70 year old hypertensive edentulous patient who was on low dose Nifedipine therapy. Patient wanted complete dentures. We planned to excise the overgrowth and followed up for 1 year. CONCLUSION: Nifedipine induced gingival enlargement noticed only in 10 % of patients. Hence, there is a need for physicians and dentist to make a coordinated treatment plan and practice care while prescribing these drugs which are associated with gingival overgrowth.

Knowledge, Attitude, and Behavior Related to Use of Miswak (Chewing Stick): A Cross-Sectional Study from Aseer Region, Saudi Arabia.

AIM: The aim of this study was to assess the oral health knowledge, behavior, and practices related to use of miswak (chewing stick) in population of Aseer Region, Saudi Arabia. SUBJECTS AND METHODS: Of the 2023 participants, 1666 (83.3%) were females and 334 (16.7%) were males. The questionnaires having 10 online questions were used to assess the knowledge of oral hygiene methods, including frequency, reason, and methods for miswak use. STATISTICAL ANALYSIS USED: The survey data were collected and organized into Microsoft Excel spreadsheets (Microsoft Inc., USA) and were statistically analyzed utilizing the Statistical Package for the Social Sciences version 20.0 software (IBM Inc., USA). The statistical test used here was the Chi-square test, and P < 0.05 was considered to be statistically significant (P < 0.05). RESULTS: Participants responded regarding the primary oral hygiene methods; 46.5% respondents used toothbrushes, 44.5% used both toothbrushing and miswak, and 8% used only miswak as their primary tooth cleaning method. 28.2% respondents cleaned their teeth with tooth brush or miswak at least once a day, 37.6% twice, 28.4% whenever required, and 5.9% infrequently. Majority of the participants, i.e. 70.2% were using miswak with taper and as a brush to clean all tooth surfaces. About 84.7% feel fresh, and teeth are whiter after the use of miswak. Nearly, 84.7% prefer to continue using miswak in combination with other teeth cleaning methods, which may have more benefits. CONCLUSIONS: In our study, most common type of oral hygiene method employed is toothbrush and in combination with miswak. Chewing stick use was common among participants with religious advice being the dominant reason for usage.

Molariform mesiodens in primary dentition.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition. A midline supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. This paper reports a rare case of the presence of a molariform mesiodens in the primary dentition. On clinical and radiographic examination, flaring of the primary central incisors was seen, with a molariform mesiodens consisting of multiple lobes or tubercles on the occlusal surface with the well-formed root. The treatment plan consisted of the extraction of the supernumerary tooth and regular observation of permanent central incisors for proper eruption and alignment.

Knowledge and Practice of Pulp Therapy in Deciduous Teeth among General Dental Practitioners in Saudi Arabia.

BACKGROUND: It has been observed that the general dentists and pedodontists differ in their treatment recommendations for pulp therapy in deciduous teeth. AIM: To determine the knowledge and practice of pulp therapy in deciduous teeth by general dental practitioners (GDP) in two cities of southern Saudi Arabia. SUBJECTS AND METHODS: Fifty GDP selected at random from government and private dental clinics were questioned about pulp therapy in deciduous teeth in Abha and Najran cities using a 10-item questionnaire. The data were analyzed using IBM SPSS software version 11.0 and descriptive statistics were obtained. RESULTS: All 50 participants responded to the survey. Pulpotomy was suggested as the first line of treatment for pulp-exposed primary tooth by 32 respondents with 44 using Buckley's formocresol and 32 applying it on the pulp for 5 minutes. 43 respondents squeeze dried the cotton pellet before application on the pulp. In pulpectomy procedure 44 respondents preferred zinc oxide eugenol as obturation material with 22 using handheld reamers and 15 using slow-speed lentilospirals for obturation. 12 respondents used obturation techniques which had no scientific relevance. In order of preference Glass ionomer cement (GIC), silver amalgam, and stainless steel crowns were the materials of choice for final restoration of endodontically treated deciduous teeth. All 50 answered in the affirmative when asked if they would like to have additional information about pulp therapy in deciduous teeth. CONCLUSION: The study concluded that general dentists were regularly performing pulp therapy in decidous teeth and therefore need to be frequently updated about these procedures.

In vivo comparison of reduction in bacterial count after caries excavation with 3 different techniques.

PURPOSE: The purpose of this in vivo study was to evaluate and compare the reduction in bacterial count in dentin after caries excavation with a spoon excavator, carbide bur, and polymer bur. METHODS: Forty-five primary molar teeth from 36 children with occlusal dentinal carious lesions without pulpal involvement were chosen and divided into 3 groups: (1) caries was excavated using a brand new round bur with a slow-speed handpiece at 800 rpm from the occlusal aspect; (2) new polymer burs were used with slow-speed handpiece at 800 rpm, according to the lesion's size; (3) caries was excavated using a sterile spoon excavator. RESULTS: The mean difference in colony forming units of Streptococcus mutans and lactobacilli before and after caries excavation was found to be significant (P<.01) in all 3 groups. Further intergroup comparison of percentage reduction in bacterial counts between different groups was statistically significant, except when the percentage reduction in S mutans of group 2 was compared to that of group 3 (P=.26). Reduction in S mutans count was highly significant (P<.001) for group 1 vs group 3. CONCLUSIONS: Caries removal with a carbide bur, polymer bur, and spoon excavator produced significant reduction in viable count of both Streptococcus mutans and lactobacilli. Carbide burs, however, produced greater reduction in the viable count of bacteria followed by polymer bur and spoon excavator.
