It has been reported that about a third of older population bears most of the root caries burden. Root surface caries is one of the significant oral health problems in the elderly, and the incidence of root surface caries has been found to be one of the major risk factors for tooth loss. Limited studies have been carried out on root caries in elderly patients in context of Nepal. Hence, the objective of this study was to find the prevalence of root caries and its associated factors among the elderly population. This observational cross sectional study was done on 188 adult patients of 60 years and above. A specifically designed questionnaire was used to collect the following information: socio-demographic characteristics, use of medication, oral hygiene practices and oral health behaviour. Data were analyzed using Chi square test and descriptive statistics were calculated. It was found that the prevalence of root caries was 61.7% and it increased with age. There was an association between root caries and socioeconomic status which showed root caries was seen more in adults of upper middle class. More of root caries was seen in females, those who were unmarried, taking medications and non vegetarians. Oral hygiene habits and oral health behaviour had a positive impact on root caries. More of root caries was seen on buccal surface of molars.

Attitude and practice of rubber dam application among dental interns during clinical procedure plays an important role in providing quality treatment and avoiding medicolegal consequences. The aim of this study was to determine the attitude and practice of dental interns towards rubber dam use. A questionnaire-based study was conducted using pre-structured questionnaire among 138 dental interns of three different colleges affiliated to Kathmandu University of Kathmandu District. The results showed that 97.1% study participants believe rubber dam gives good isolation, moisture control and safety. Positive attitude was shown by 55.1% of intern toward rubber dam use during all procedures and 64.5% during root canal treatment. Of the total, 73.2% believed they lacked training and 92.2% were willing to take more training. Most of the interns (85.5%) believe rubber dam as helpful tool. In conclusion, majority of the interns believe rubber dam gives good isolation, moisture control and safety but their lack of rubber dam use in clinical practice could be due to insufficient training, patients' objection and extra time needed for placement. To overcome this, more trainings, preclinical and clinical demonstration and mandatory use during all clinical posting should be done in dental colleges.

Dental caries not only affects the quality of life but also brings economic burden to individual and society. The aim of this study was to determine the prevalence of dental caries and associated factors among patients. An analytical, cross-sectional study was conducted among the patients visiting Department of Oral Medicine of Nepal Medical College Dental Hospital of Kathmandu. The results showed that overall prevalence of dental caries was 81.6%. Dental caries among participants between 25-34 years was highest (33.1%) and more among females (84.9%). Majority of the participants used toothbrush 96.8%, while 78.3% used fluoridated toothpaste. Even though most study participants claimed to use toothbrush and fluoridated toothpaste, prevalence of dental caries was high.

The major reason for patient not opting for RCT is due to lack of knowledge. The factors that discourage the patient and hinder the treatment when identified will help the understanding of the clinician to adequately address the issue. Thus, this study with aim to assess the knowledge, awareness and expectation of RCT from patients' perspective was undertaken. This survey was conducted with pre-structured questionnaire consisting of 13 questions and were distributed to random 404 patients attending the department. The completed questionnaire was the analyzed. 61.4 % of participants had knowledge of RCT. Participants with previous experience of RCT were more likely to undertake the procedure again despite the cost issue, when required, then those who had no previous experience.72% of the participants choose specialized service. In comparison to other studies the knowledge and awareness regarding RCT was higher in this study.

Cross sectional studies from different countries shows that there is varying degree of prevalence of periradicular radiolucencies (PR) in root filled teeth. Since no such prevalence studies have been done in Nepal, we are unaware of the existing problem in our population. Thus, aim of this study was to investigate the prevalence of periradicular radiolucencies and its association with the quality of root canal treatment and coronal restorations in an adult Nepali population. Among 350 patients, 40.8% (389) presented with PR. Significantly better outcome was seen in teeth with adequate qualities of root filled teeth and coronal restoration. The prevalence of PR in Nepali population was seen relatively high and the considerable efforts to i...

With the advent of Bioceramic sealers and their beneficial biological properties, they have been widely incorporated in clinical practice. So, the purpose of this study was to find out the difference in the healing outcome of root canal treatments and retreatments carried out with either single cone obturation technique (SCO) or warm vertical compaction technique (WVC). This was observational analytical study (Cohort study), carried out in private practice. The patients were recalled at-least at six months. When association of healing with type of sealer was considered there was a statistically significant association between healing potential and type of sealer (p-value 0.03). Kaplan-Meier analysis for time to healing showed that with progress of time probability of healing was seen to be more in bioceramic sealer group. Within the limitations of this study the SCO had good healing potential and can be used as a safe alternative in obturation.
