High consumption of these cariogenic food and drinks for prolonged time may result in dental erosion and severe tooth decay. The aim of this report is to present a patient who had rampant caries and aesthetic problems resulting from his cariogenic habits. A 22-year-old man referred to our clinic with rampant caries. The patient who was stressed and anxious had also aesthetic concerns. Although he had no systemic-health problems, his oral hygiene was extremely poor. The diagnosis was severe tooth decay, multiple erosive lesions at different stages and concomitant gingivitis. The anamnesis revealed the history of consuming ~4-5 L cola and ~30-40 pieces of peppermint every day during the past 4 years. The patient also reported that he had nausea reflex and constantly chewed mentholated gum to inhibit his discomfort. The full-mouth rehabilitation was achieved with a multidisciplinary approach within the limitation of the patient cooperation. In the case of high intake of acidogenic food and drinks that caused severe tooth decay, the treatment procedures experienced were challenging. Thus, patient education/motivation and counselling on cariogenic habits were considered in multidisciplinary treatment planning for the prosperous prognosis of the case. ","PeriodicalId":76664,"journal":{"name":"The Journal of the American College of Dentists","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87355609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The safety of this drug therapy is presently controversial. Although formocresol has the potential for malignant transformation, it has a long term track record of safety. Decreased formocresol pulpal therapy utilization has the potential to limit tooth preservation globally, especially in pediatric patients. Issues regarding carcinogenicity, toxicology, and mutagenesis are discussed. Further issues such as expense, ease of administration, availability, and effectiveness are also discussed. A review of the published literature regarding formocresol case reports is investigated. In conclusion, although formocresol has several known problematic side-effects, it is the opinion of the authors that when properly utilized as a pulpal medicament, formocresol is safe, inexpensive, readily available, easily administered, and effective. ","PeriodicalId":76664,"journal":{"name":"The Journal of the American College of Dentists","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90421555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the long-term histological sequences are largely unknown.\u0000Objectives: The present study is to evaluate the histological and ultrastructural effects of BoNTA on submandibular salivary gland (SSG).\u0000Methods: Eighteen 6-week-old male albino rats received 0.1 ml of either saline (sham group, n=9) or BoNTA (BoNTA group, n=9) injection in the right SSGs. Of 9 rats in each group, 3 were terminated at 2, 4 and 12 weeks after the injection. The harvested SSGs were embedded and sectioned at 6µm, and stained with H&E for histological study. Ultrathin sections (60-90nm) were cut from1 mm3 pieces harvested from the center of SSGs, and mounted on copper grids for ultrastructural study using transmission electron microscope (TEM). \u0000Results: All sham SSGs showed normal acinar cells with rounded nuclei and regular striated ducts (SD) with characteristic basal striations. By TEM, acinar cells exhibited rounded nuclei, mitochondria, and secretory granules at cytoplasm. Numerous mitochondria presented in SD. Compared with these features, 2-week BoNTA-injected SSGs showed loss of spherical fashion and basal striations in serous acini and SD respectively, and the cell boundaries were not clear. TEM further revealed irregular nuclei of acinar cells and SD, and swollen mitochondria. In 4-week SSGs, some acini and ducts lost their spherical fashion and in some areas, these structures disappeared. Ruptured mitochondria were observed in acini and SD by TEM. However, all 12-week BoNTA-injected SSGs seemed to have similar structures to those of sham SSGs. By using scoring system for semi-quantifying the histological structural changes of BoNTA-injected SSGs, 2- and 4-week BoNTA-injected SSGs showed significantly higher scores as compared with their sham counterparts. However, no significant score difference was found between 12-week BoNTA-injected and sham SSGs. \u0000Conclusions: Although application of BoNTA results in significant changes in histological structures and ultrastructures of SSGs, these detrimental effects seems to be transient, and the major recovery occurs in 3 months. Thus, BoNTA can be used for treating SSG hyperfunction. ","PeriodicalId":76664,"journal":{"name":"The Journal of the American College of Dentists","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75388967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two different digital model software programs, Orthomodel (v.1.01, Orthomodel Inc., Istanbul, Turkey) and O3DM (v.2.0, O3DM Thunoegade, Aarhus C, Denmark) were used for diagnostic measurements including tooth width, Bolton discrepancies, intermolar and intercanine distances. A total of 34 measurements were calculated on each digital model. All measurements were repeated by the same observer over 10 randomly selected dental casts at least two weeks later for intraobserver reliability. Results were analyzed statistically. The paired samples t-test was used to compare the differences between the measurements obtained with both softwares. The intraobserver reliability was determined using Cronbach’s alpha test.\u0000Results: Cronbach’s alpha value indicated a very high level of reliability for all measurements. Orthomodel and O3DM software programs showed significant differences in the mesiodistal widths of some teeth and the sum of maxillary 6 teeth widths (p<0.05), but not in the Bolton ratios and transverse arch width measurements.\u0000Conclusions: Both digital model softwares demonstrated clinically acceptable measurements despite of the differences in some measurements essential for diagnosis and treatment planning. ","PeriodicalId":76664,"journal":{"name":"The Journal of the American College of Dentists","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83105212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
