During root canal instrumentation, soft tissue or debris get impacted in the apical region causing canal blockage. This can be avoided if apical patency is maintained. A major concern over apical patency is extrusion causing periapical tissue irritation and delaying or hindering periapical healing. The aim of this review was to evaluate the literature regarding the influence of apical patency on success of root canal treatment. A search of the literature was conducted via PubMed using the terms “apical patency” OR “patency file”. Inclusion criteria were: articles published in English, between the years 2000 and 2020, and were neither case reports nor reviews. A total of 32 articles were selected. Clinical studies directly investigating the influence of apical patency on root canal treatment outcome are limited. In-vitro and in-vivo studies were found evaluating amount of extrusion, canal cleanliness, and shaping associated with apical patency examined this influence indirectly. According to the available literature, there is little evidence to contraindicate the use of apical patency or suggest it has a negative effect on root canal treatment outcome. However, more evidence of high quality is required to confirm this.","PeriodicalId":35469,"journal":{"name":"Journal of Stomatology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71124858","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 most common canal dressing is calcium hydroxide. Apart from its well-known benefits, calcium hydroxide is considered difficult to be completely removed from root canal system. In the literature, in an assessment of the effect of material removal from root canals, superiority of some instruments over the other are reported. Objectives: The aim of the study was to analyze the impact of Brush-Finisher on removing an intra-canal dressing in different root canal widths. Material and methods: The study was performed using extracted single-rooted teeth, which were prepared to standardize all samples and divided into 2 groups, including large canals (LC, n = 8) and narrow canals (NC, n = 8) groups. As a control group of narrow and wide canals, a syringe with an endodontic needle was used (LC, n = 8 and NC, n = 8). Calcium hydroxide paste was placed into the canals. After 2 weeks, cleaning procedure was performed using 2% NaOCl and a Brush-Finisher. After agitation of the rinsing solution, radiographs were taken in bucco-lingual and mesio-distal projections. Then, all radiographs were uploaded to graphic software, and the roots were divided into 3 parts: apical, middle, and coronal, and a crisscross pattern was carried out. Every square field located along the course of canal was calculated and evaluated in terms of the absence or presence of canal dressing. P-value of < 0.05 was assumed statistically significant. For comparison of individual proportions, N-1 χ2 test was used, while Marascuilo procedure was applied to evaluate significance between particular comparison of pairs. Results: Significant difference between efficacy of Ca(OH)2 removal was observed comparing middle and coronal level in LC group (0.077) as well as between apical and middle level (0.106) and coronal and middle level (0.082) in NC group. Conclusions: Activation of irrigation with the Brush-Finisher was more beneficial in removing Ca(OH)2 in narrow rather than large canals. Cleaning was less efficient in middle levels of both groups.","PeriodicalId":35469,"journal":{"name":"Journal of Stomatology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71124955","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}

This causes great discomfort for the patient as well as huge labor and time-consuming procedures for dentists and dental technicians. Objectives: The purpose of this study was to evaluate the adhesion between self-curing acrylic material and teeth in distillate water and denture disinfection agent. Material and methods: Five types of self-cure acrylic resin samples’ groups were prepared for the study, and were combined with acrylic teeth. First group included teeth samples made without surface modification, second group consisted of teeth samples’ surfaces activated with acetone, while in third group, retention holes were made. In fourth group of samples, their surfaces were increased by retention holes and washed twice with monomer, whereas in fifth group of teeth, cervical layers were grinded with a bur. One plate from each group was stored in distilled water (W) and another in Corega Tabs (CT) solution for 30 days at 37 o C. Connection between acrylic resin-acrylic tooth was assessed using tensile strength instrument. Results: The highest bonding force was achieved between Villacryl SP and Mifam teeth in the group with retention holes made and surface washed twice with monomer (W: 149.86 ± 5.42 N; CT: 146.38 ± 4.39 N), cohesive type. The lowest adhesion values were observed for tooth surfaces with no changed surface (W: 15.15 ± 3.44 N; CT: 13.49 ± 3.80 N), and with samples washed with acetone (W: 15.8 ± 3.22 N; CT: 12.0 ± 1.0 N). In these cases, the connection had adhesive character. Conclusions: A proper connection between acrylic teeth and surface of denture base is possible to achieve when both chemical and mechanical methods surface are combined, thus increased by retention elements. cleaning agent.","PeriodicalId":35469,"journal":{"name":"Journal of Stomatology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71125635","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}

Unfortunately, current literature emphasizes their negative effect on the condition of soft tissues of the oral cavity and hard dental tissues. Objectives: The aim of the study was to assess the effect of types of inhaled anti-asthmatic drugs on the properties of saliva in children. Material and methods: Study group included 114 asthmatics and 94 healthy patients between the age of 3 and 17. Information about the age of onset, severity of asthma, use of anti-asthmatic medications, duration of the therapy, method of drugs’ administration, and number of their application were recorded. The severity of asthma was assessed by a pediatrician. Saliva was collected for resting pH, buffering capacity, hydration, saliva quantity, and viscosity measurements using saliva-check buffer kit (GC). Student’s t-test, c2 test, Mann-Whitney U test, and Spearman’s correlation coefficient were used, with a significance level of p < 0.05. Results: Asthmatics appeared to be characterized by significantly lower average values of saliva quantity (p = 0.0064), buffering capacity (p = 0.0002), and viscosity (p = 0.0094) than controls. Spearman’s rank correlation revealed a negative correlation between steroid dose, therapy duration, and the use of dry powder inhalers (DPIs) on saliva quantity. Moreover, combination therapy with β2-agonists and DPIs reduces hydration of lip mucosa. Finally, the use of DPIs increases the viscosity of saliva.

Objectives: The aim of this study was to compare SOHO-5 (parental version and child’s self-reports) and ECOHIS in a sample of Chilean preschoolers. Material and methods: 121 pairs were selected from the Pablo Neruda School in Curanilahue, Chile. Collection of dmft/DMFT indices, socio-demographic data, and application of instruments were performed in the facilities of the school. Parents answered ECOHIS and SOHO-5p (parental version), and children answered SOHO-5c (child’s self-reports). Mann-Whitney U test and Spearman’s correlation coefficients were used for statistical analysis. Results: SOHO-5p and ECOHIS were strongly correlated. Moreover, SOHO-5p and ECOHIS could discriminate between preschoolers with and without severe caries. In contrast, SOHO-5c did not correlated with SOHO-5p, nor ECOHIS. In addition, SOHO-5c could not distinguish between the presence and absence of severe caries among the sample. Conclusions: ECOHIS and SOHO-5p were both significantly correlated with OHRQoL among preschoolers. How-ever, SOHO-5c did not correlate with any of the variables studied, nor with SOHO-p or ECOHIS.

The main aim of the study was the assessment of new dental caries detection methods: digital fiber-optic transillumination (DIFOTI) and quantitative light-induced fluorescence (QLF), in comparison with conventional method: visual and tactile examination. Objectives: Specific aims were the comparison of efficacy of diagnostic devices, including DIAGNOcam (DIFOTI), DIAGNOdent pen, and VistaCam iX (QLF) in early caries detection in children, and the assessment of their sensitivity and specificity. Material and methods: In total, 61 children, aged 5-18 were examined. Early caries (caries incipiens) on occlusal and approximal surfaces of molar deciduous, and permanent teeth and premolar teeth were diagnosed. Examination scheme included visual and tactile examination according to ICDAS-II (international caries detection and assessment system), and assessment of dental caries with VistaCam iX, DIAGNOdent pen, and DIAGNOcam devices. Results: 227 surfaces were examined, including 129 permanent molars’ surfaces, 50 deciduous molars’ surfaces, and 48 premolars’ surfaces. Therefore in total, 172 occlusal surfaces and 55 approximal surfaces were analyzed. The highest sensitivity was obtained with VistaCam iX – 0.9655, lower DIAGNOcam – 0.8649, and DIAGNOdent pen – 0.6410. The highest specificity was obtained with DIAGNOdent pen – 0.9043, lower VistaCam iX – 0.9028, and DIAGNOcam – 0.8947. Conclusions: The clinical visual and tactile examination should be the basic diagnostic method, and their results should be confirmed with additional devices, such as VistaCam iX, DIAGNOcam, or DIAGNOdent pen. None of the mentioned modern devices provided total efficacy in early caries detection. VistaCam iX and DIAGNOcam obtained better sensitivity than DIAGNOdent pen; however, all devices achieved high specificity.","PeriodicalId":35469,"journal":{"name":"Journal of Stomatology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71124620","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 canal adjacent to the molar triangle may have different variants that occur at different frequencies. This canal constitutes 46.67% of all mandibular canal branches, making it the most common type of bifurcation, next to the canal branching upstream, buccal-lingual and to the tooth root. Thomas von Arx et al. classified variants of the alignment of the retromolar canal and distinguished five types. The retromolar canal and its content may be of great clinical importance for doctors in the area of the retromolar triangle. The retromolar nerve may contribute to inadequate anesthesia around the retromolar triangle, but this problem can be solved by techniques other than traditional anesthesia. Working in this area, doctors should take into account the possibility of damaging the neurovascular bundle. The analysis of the available literature show that the retromolar canal is not a rare phenomenon in the population.
