Introduction: Assessment of root canal treatment (RCT) quality performed by undergraduate students is important in evaluating the teaching of endodontic. Hence, this study aims to evaluate the obturation quality of root canal treated teeth and the number of visits required by patients to complete RCT rendered by undergraduate students in School of Dental Sciences, Universiti Sains Malaysia (USM). Methods: All RCT cases performed by fourth year and final year undergraduate dental students in 2017/2018 were included in this study with a total of 258 teeth. Both digital and conventional periapical radiographs of all treated teeth were assessed. Evaluation of the obturation quality was classified as acceptable and unacceptable based on the length in relation to the radiographic apex and density of the obturation in relation to the presence of voids. The number of visits required to complete each RCT case by the students were also assessed. Results: Out of the total 258 teeth, 63.6% were maxillary and 36.4% were mandibular comprising 53.5% anteriors, 14.7% premolars and 31.8% molars. Overall acceptable obturation quality was 71.3%. There was significant association between obturation quality and type of teeth as well as location of teeth. Conclusion: Students in this institution performed significantly better obturation quality on anterior teeth than on premolars and molars as well as on maxillary teeth as compared to the mandibular teeth. Patients seemed to require more visits for RCT of molars than anteriors and premolars.

ABSTRACT Head and neck cancer patients require oral assessment and management prior, during and after cancer treatment to minimise oral complications. Hence, this study aimed to evaluate sociodemographic data, oral health management, oral complications derived from cancer treatment, time frame in completing dental treatment and association between oral management and complications. Purposive record sampling of head and neck cancer patients who completed radiotherapy and/or chemotherapy at Hospital Universiti Sains Malaysia (HUSM) from 2011 to 2017 were reviewed. A checklist was used to record the data and analysed using descriptive statistics and Pearson Chi-square test. A number of 194 patient records were reviewed with majority were Malays (88.1%), males (61.3%) with the mean age of 57.18 years old. Only 21% of the patients had oral assessment prior to cancer treatment. About 84% of the referred patients were dentally fit within 1 month. Mucositis and fungal infections were the most prevalent complications. The relationship between oral assessment prior to cancer treatment and oral complications was not significant (p = 0.134). Despite the insignificant association due to several limitations, oral assessment and management prior, during and after cancer therapy are recognised as crucial for improving quality of life. A standard institutional operating procedure is recommended to improve patient care.
