Dental caries, tobacco usage and associated risk factor of dental caries in patients visiting a government hospital in Western, Nepal.

BACKGROUND: This study was conducted to assess the prevalence of dental caries, tobacco usage, and associated risk factors for dental caries in patients who visited a government hospital in Western, Nepal. METHODS: This analytical cross-sectional study was conducted from January to April 2022. Patients above 18 years visiting the dental OPD of a government hospital, and who had provided informed consent were enrolled in the study using a convenience sampling technique. As the study also involved an illiterate population, in that case, informed consent was obtained from their respective legal guardian as well. A pretested standardized, close-ended questionnaire was administered by researchers to gather information regarding the associated risk factors and oral hygiene practices. Clinical examination was done for dental caries according to the criteria by the World Health Organization (WHO) using the "DMFT" index (WHO modification 1987). Bivariate and multivariable logistic regression was done and the odds ratio and p-value was calculated. For all tests, statistical significance was set at p < 0.05. RESULTS: A total of 219 participants completed the study with a mean age of 31.73 ± 12.46. The prevalence of dental caries and tobacco was found to be 80.36% and 5.02% respectively. Participants without health insurance had 2.35 times higher odds of dental caries (95% CI: 1.03-5.36). Not rinsing the mouth after eating sweets was associated with 3.07 times higher odds of dental caries (95% CI: 1.31-7.18). Those who hadn't visited a dentist in the past 12 months had lower odds (0.42; 95% CI: 0.18-0.94). Eating fresh fruit daily showed statistically higher odds (2.70; 95% CI: 1.04-6.99) of dental caries. Non-tobacco users had higher odds (14.19; 2.55-78.99) of dental caries. CONCLUSION: Dental caries is highly prevalent, while tobacco usage is relatively low. Factors associated with dental caries included lack of health insurance coverage, consumption of fruits once daily, recent dental visits within the past year, not rinsing the mouth with water after consuming sweets, and non-tobacco users.

Mandibular Third Molar Impaction among Patients Visiting Outpatient Dental Department of a Tertiary Care Centre.

Introduction: Mandibular third molar impaction is the most common impaction as third molars are last to erupt at the age of 17-25 years. Despite its high prevalence and negative impacts, there is limited study about mandibular third molar impaction. The aim of this study is to find out the prevalence of mandibular third molar impaction among patients visiting the outpatient Dental Department of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients visiting the Outpatient Dental Department of a tertiary care centre from 1 January 2023 to 30 June 2023. Ethical approval was taken from the Institutional Review Committee of the same institute. A total of 414 orthopantomograms were prospectively reviewed for the angulation of impaction, depth and position. The indication for extraction was recorded from patients' cards during the time of extraction. Convenience sampling method was used. The point estimate at a 95% confidence interval was calculated. Results: The prevalence of mandibular third molar impaction was 37.13% (34.29-39.97, 95% Confidence Interval). There was a high prevalence of mesioangular 344 (45.38%) pattern followed by vertical 249 (32.85%) for mandibular third molar impaction, the most commonly involved group was 20-30 years, with female 247 (59.70%) predominance. Bilateral impaction 344 (83.10%) was more prevalent than unilateral. Depth A, 639 (84.3%), ramus relation level I, 602 (79.42%) was the most common level of impaction. Recurrent pericoronitis 160 (38.6%) was the common indication for extraction followed by dental caries 145 (35%). Conclusions: The prevalence of mandibular third molar impaction was lower than other similar studies done in similar settings. Keywords: impacted tooth; pericoronitis; prevalence; third molar.

Demographic Profile and Outcome of Pediatric Intensive Care Unit.

BACKGROUND: Pediatric intensive care provides better observation as well as an intensive treatment, which helps to cure, support, and provide better outcomes for sick children. This study aimed to describe the demographic profile and the outcome of PICU patients, and evaluate the relationship of diagnostic categories with treatment and outcome. METHODS: This retrospective cross-sectional study was conducted in a six-bedded PICU from 1 March 2021 to 1 March 2022. Bivariate analysis was used to identify the association between dependent and independent variables. RESULTS: The infants admitted below 6 months of age were 63 (22.3%) and had male predominance accounting for 64%. The main portal of entry of the admitted cases was emergency ward 214(75.6%). Most of the patients 153(54.1%) were admitted for intensive monitoring of their abnormal vitals along with critical care according to our PICU protocol. Respiratory illness 122(43.1%), neurosurgical illness 59(20.8%), and primary infectious disease 52(18.3%) were the common reason for PICU admission. Post-major surgery 2(66.7%), hematological illness 3(37.5%), and cardiac disorders 1(20%) had high mortality rates. Among the portal of admission, the majority of the children (80.0 %) who were admitted to the PICU through the emergency ward died before exiting from the PICU (p<0.0001). CONCLUSIONS: Respiratory illness was the most common cause of admission and post-major surgery had the highest mortality rate. Portal of entry was statistically associated with patient characteristics and had a significant relationship with the outcome. Similar studies in other health institutions are required to further analyze the demographic profile and outcome of pediatric critical care in Nepal.
