The use of re-surgery in the treatment of teeth with severe sensitivity in the buccal mucous membrane: A case report with 75 months follow-up

BACKGROUND AND AIM: A periapical endodontic surgery is an alternative treatment when teeth are not responding to conventional treatment and endodontic re-treatment. CASE REPORT: The following case report presents a clinical case of maxillary right and left central incisors with unsatisfying endodontic surgery and severe sensitivity in the buccal mucous membrane. Radiographic examination revealed several fragments of amalgam as root-end filling material, surrounded by a periapical radiolucent area. The chosen treatment plan was to perform endodontic retreatment. Symptoms persisted in spite of the gutta-percha removal and calcium hydroxide intracanal medication. Hence, periradicular re-surgery was performed. However, deep tissue penetrated amalgam particles were difficult to explore and could not be removed completely. The root-end filling was done with mineral trioxide aggregate (MTA), and the lesion was subjected to histologic analyses. The treatment was successful due to the absence of painful symptoms and due to periapical bone repair after 75 months follow-up. CONCLUSION: MTA can be used successfully in the situations with failed previous periradicular surgery with amalgam.

Oral Health-Related Quality of Life among Children Aged 11-14 Years Old with and without Parental Care in South-East of Iran

Objective: To measure the Oral Health-Related Quality of Life (OHRQoL) and compare children with and without parental care. Material and Methods: This cross-sectional study was conducted on 160 schoolchildren with parental care and 100 orphans in Kerman, Iran. After fulfilling the questionnaire voluntarily, a clinical examination was performed, and indices such as decayed, missing, and filled teeth (DMFT), molar-incisor hypoplasia (MIH), modified gingival index (MGI), traumatic dental injury (TDI), and malocclusion were recorded. Data were statistically analyzed using SPSS version 25 via the ANOVA, Pearson\u27s correlation coefficient test, Chi-Square test, and descriptive statistics. Results: Children without parents scored poorly for OHQRoL items compared to those with parents (p<0.001). DMFT was not significantly related to OHRQoL; however, missing teeth were correlated with the CPQ11-14 overall. Also, the TDI index had a significant relationship with CPQ mean score (p=0.02). Moreover, the difference in the mean CPQ11-14 score in children with TDI in the two groups was significant regarding the quality of life (0.031). Conclusion: OHRQoL differed significantly between children in the two groups, which can be influenced by gender and habits. Due to the vulnerability of welfare-supported children without parental care, these findings emphasize the value of preventive and health-promoting measures for this group of children

T he Use of Different Study Skills by Undergraduate and Postgraduate Students of Kerman Dental School

Background: Different study skills have been developed and introduced, although most learners are apparently unaware of them. Objectives: This study was conducted to investigate the frequency of using different study skills among undergraduate and postgraduate students. Method: The study population consisted of 201 undergraduate and 45 postgraduate students of Kerman Dental School in 2016-2017, who were selected using the random stratified sampling method. A questionnaire composed of four questions used to collect data. The questionnaire was a modified version of the one used by Karpiacke et al. The frequency of using different study skills (i.e., re-studying, re-writing, using flashcards, studying in groups, memorizing, teaching content, creating headings, self-testing, highlighting, finding connections, and finding real examples) was asked in the first question. Students’ preparation for exams and students’ satisfaction with their study skills were asked in the next questions. Data was analyzed using the chi-square test in SPSS23. Results: Of the 246 participants, 72 (35.8%) undergraduate students and 20 (44.4%) postgraduate students were male. The frequency of using different study skills was the same between the male and female undergraduate students, except for re-writing (P=0.024), studying in groups (P=0.018), and creating headings (P=0.018) which were higher in the female undergraduate students. However, there was no significant difference between male and female postgraduate students in terms of the frequency of using different study skills. Conclusion: The most and least commonly used strategies by the undergraduate and postgraduate students were re-studying and using flashcards, respectively. Only 30.3% of the undergraduate and 24.4% of the postgraduate students used the self-testing strategy. Keywords: Study skills, study strategies, students, dental schoo

The use of re-surgery in the treatment of teeth with severe sensitivity in the buccal mucous membrane: A case report with 75 months follow-up

BACKGROUND AND AIM: A periapical endodontic surgery is an alternative treatment when teeth are not responding to conventional treatment and endodontic re-treatment. CASE REPORT: The following case report presents a clinical case of maxillary right and left central incisors with unsatisfying endodontic surgery and severe sensitivity in the buccal mucous membrane. Radiographic examination revealed several fragments of amalgam as root-end filling material, surrounded by a periapical radiolucent area. The chosen treatment plan was to perform endodontic retreatment. Symptoms persisted in spite of the gutta-percha removal and calcium hydroxide intracanal medication. Hence, periradicular re-surgery was performed. However, deep tissue penetrated amalgam particles were difficult to explore and could not be removed completely. The root-end filling was done with mineral trioxide aggregate (MTA), and the lesion was subjected to histologic analyses. The treatment was successful due to the absence of painful symptoms and due to periapical bone repair after 75 months follow-up. CONCLUSION: MTA can be used successfully in the situations with failed previous periradicular surgery with amalgam
