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

A systematic review of medicinal plants and herbal products' effectiveness in oral health and dental cure with health promotion approach

Medicinal plants and herbal drugs are being used increasingly as part of primary health care in most parts of the world. As important adjunctive and alternative treatments for oral health care, herbal products' use may continue to increase and become more widespread. The objective of this study is to present a comprehensive systematic review of the current published literature on the effectiveness of medicinal plants and herbal products employed to improve oral health in adolescents with a health promotion approach. The systematic review was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The keywords “herbal medicine,” “herbal extract,” “herbal supplements,” “plant extract,” “natural drug,” “pulpitis,” “dental caries,” “oral viral diseases,” and “abscess” were used in combination with the Boolean operators OR and AND. PubMed, Embase, Scopus, and Web of Science were searched. Quality assessment of the included studies was performed using the Cochrane Handbook for Systematic Reviews of Interventions. The search yielded 49 original research studies. A total of 22 studies had low or unclear risk bias. The geographical distribution of included studies was primarily concentrated on western countries. Overall, studies reported herbal product users' age, ranging from young adults aged 18 years to elderly people aged 75 years or older. Most studies reported multiple compounds, including herbal drugs and herbal extracts. Chamomile and Aloe vera were the most frequently reported herbal compounds. The most commonly described herbal products to treat oral diseases were gels, mouth rinses, and pastes. The studies included a range of people with oral diseases, including periodontal and gingival diseases, recurrent aphthous stomatitis, oral lichen planus, and oral candidiasis. Herbal product interventions were found to be effective and safe alternatives for oral health care. One of the most important goals of the World Health Organization (until 2015) is the oral health index, so it is important that dental services be followed up more seriously. Considering the problems in reaching this goal of the World Health Organization in our country, herbal products have the ability to improve clinical oral health outcomes in adolescents. Limited adverse side effects indicate the overall safety of these treatments for a wide range of oral diseases. Therefore, the use of medicinal plants as well as alternative medicine is one of the useful methods in achieving this important goal of public health

The effects of neonatal maternal deprivation and chronic unpredictable stresses on migraine-like behaviors in adult rats

Background: Stress is known to cause migraine. This study investigates the effects of neonatal maternal deprivation (MD) and chronic unpredictable stress (CUS) on migraine in rats. Methods: Seventy rats were randomly divided into ten groups (five groups of each sex, and seven rats/group). The groups included: untreated intact, nitroglycerin (NTG) only, NTG + MD, NTG + CUS (10 weeks after birth), and NTG + MD + CUS. For the induction of MD, pups were separated from their mothers from postnatal day 2 to day 14. The CUS was conducted by daily exposure to different stressors for 2 weeks. For the induction of migraine after stress, NTG (5 mg/kg/IP) was administered every second day for 9 days. Afterward, NTG-related symptoms, including climbing behavior, facial rubbing, body grooming, freezing behavior, and head-scratching, were recorded for 90 min. Statistical differences between the groups were analyzed by one-way and two-way ANOVA followed by the Newman–Keuls test. Results: Migraine symptoms, including increased head-scratching, facial rubbing, and decreased climbing behavior, were more significant in females than in males. Head scratching and facial rubbing increased in stressed females, but not in males as compared to NTG-treated rats. Body grooming was significantly decreased in MD males compared to the NTG group. The effects of NTG in MD + CUS on the rats did not differ from those in the MD or CUS groups. Conclusions: MD and CUS had a sex-related aggravating effect on the development of migraine, while the combination of MD and CUS had no additive migraine-aggravating effect
