Reciprocating Systems

The objective of the present study was to evaluate and compare the dentin removal capacity of Endogal Kids and Reciproc Blue NiTi alloy endodontic reciprocating systems for root canal treatments in primary second molar teeth via a micro-computed tomography (micro-CT) scan. Materials and Methods: Sixty root canal systems in fifteen primary second molar teeth were chosen and classified into one of the following study groups: A: EK3 Endogal Kids (n = 30) (EDG) and B. R25 Reciproc Blue (n = 30) (RB). Preoperative and postoperative micro-CT scans were uploaded into image processing software to analyze the changes in the volume of root canal dentin using a mathematical algorithm that enabled progressive differentiation between neighboring pixels after defining and segmenting the root canal systems in both micro-CT scans. Volumetric variations in the root canal system and the root canal third were calculated using a t-test for independent samples or a nonparametric Mann–Whitney–Wilcoxon test. Results: Statistically significant differences (p = 0.0066) in dentin removal capacity were found between the EDG (2.89 ± 1.26 mm3) and RB (1.22 ± 0.58 mm3) study groups for the coronal root canal third; however, no statistically significant differences were found for the middle (p = 0.4864) and apical (p = 0.6276) root canal thirds. Conclusions: Endogal and Reciproc Blue NiTi endodontic reciprocating systems showed similar capacity for the removal of root canal dentin, except for the coronal root canal third, in which the Reciproc Blue NiTi endodontic reciprocating system preserved more root canal dentin tissue.

Second Mesiobuccal Canal

Objectives: To determine the frequency of second mesiobuccal canal (MB2) in a sample of 223 extracted maxillary permanent 1st molars. Study Design: In-vitro Cross-sectional study. Setting: Department of Endodontic at Peshawar Dental Hospital. Period: June 2019-Nov 2019. Material & Methods: The samples were processed with application of the Clearing Technique which includes demineralization with nitric acid, dehydration with ethanol and clearing with methyl salicylate. The samples were classified according to Weine’s system of root canal classification. Results: Among the 223 samples, 30% were found to have Weine’s type1 root canal in the mesiobuccal root (second mesiobuccal canal absent).  Second mesiobuccal canal was present in majority of the samples (70%) with Weines type2 (2-1) predominant with 23.32%, Weines type3 (2-2) present in 15.7% and Weines type 4 (1-2) present in 21% of the samples. 9% of the samples could not fit into Weines classification so they were placed in Vertuccis classification for root canal system type 6 (2-1-2). Conclusion: The present study concludes that the second mesiobuccal canal is more frequently found in maxillary permanent 1st molar teeth than our textbooks report, irrespective of quadrant and gender. Therefore, time should be given to evaluation of its anatomy by the clinician before starting the root canal treatment for the greater good of the community.

ABSTRACT Introduction The success of endodontic therapy depends upon the ability of the clinician to locate, clean, shape and completely obturate all the root canal systems present in a tooth. In the recent times number of additional canals vs traditional canals has been very striking and pointing toward a greater degree of variation in the root canal morphology which needs to studied, understood and born in mind during practice so as to enhance the success. Introduction of surgical operating microscope is a major breakthrough in enhancement of vision in endodontics which not only gives required magnification but also coaxial illumination and video output. These facilities should be of a great help in location of small otherwise difficult to locate accessory canals. Materials and methods This in vivo study was planned to study variations in the canal anatomy of maxillary and mandibular first molar using surgical operating microscope using 200 first molar teeth, 100 maxillary and 100 mandibular groups, each group to be divided into 50 males and 50 female subgroups. After access opening chambers were cleaned, dried and observed and imaged under the microscope. Results The observations were recorded and incidences of variations in anatomy were analyzed subjecting the same to SPSS version 16.0. Conclusion It was observed that surgical operating microscope enhances clinician's ability to locate additional canals in the teeth. How to cite this article Abrar BAS, Pawar MG.

Abstract: In children, caries occurs mostly at the age of 6 to 9 years. At the age of 6 years permanent molar teeth begin to erupt, therefore, they are more susceptible to caries. Moreover, at the age of 9 years, a period of mingled teeth where the number of permanent teeth and of the milk teeth are nearly the same. This study aimed to obtain the prevalence of dental caries of the first permanent molar among students of elementary schools in South Tomohon. This was a descriptive study with a cross-sectional design. The population of this study was 72 students aged 6-9 years old. Samples were obtained by using total sampling method. Primary data were obtained by examination of the teeth and mouth. The results showed that the prevalence of caries among students of elementary schools in South Tomohon was 68.1% (49 students). Based on gender, caries were most frequent among males (68.4%). Based on age, caries were most frequent among students of 8 years old (79.2%). Based on tooth element, tooth 36 had the highest incidence of caries (37.2%). Based on the severity of caries, dentine caries was the most frequent (46.51%).Keywords: dental caries, the first permanent molarAbstrak: Karies merupakan penyakit yang banyak menyerang anak-anak terutama umur 6 sampai 9 tahun.

Apical Displacement

Taurodontism is the consequence of a developmental disorder in which the invagination of Hertwig's epithelial root sheath doesn't occur at a proper level. As a result, the pulp body and the chamber of a multi-root tooth, usually permanent molar teeth, are enlarged by the apical displacement of the pulp floor. Despite its clinically normal appearance, the morphological variation of this tooth can be diagnosed by a routine radiographic exam that shows enlarged apico-occlusal pulp chamber and short roots. Due to these anatomical variations, endodontic treatment of a taurodontic element is a clinical challenge given the complexity of localization and instrumentation of the root canal system. According to the degree of displacement of the pulp floor, taurodontism can be classified as: hypotaurodontism, mesotaurodontism and hypertaurodontism. This study objective is to report a clinical case of a patient who was submitted to endodontic treatment of the second inferior molar affected by hypertaurodontism.

ABSTRACT Aim To evaluate the interference of the intracanal medication Calen® (SSWhite, São Paulo, Brazil) on the filling of simulated lateral canals. Materials and methods Twenty human anterior teeth were used. Before the endodontic filling procedures the access of cavity was made, and after this root canals were made in all the teeth to simulate the presence of lateral canals. After preparation, the teeth were randomly divided into two groups (n=10). In group I, the root canal system was filled directly after chemicalmechanical preparation; in group II, endodontic treatment was performed in multiple sessions, and after preparation the calcium hydroxide-based intracanal medication Calen® was inserted. After the period of 7 days, the root canals were vigorously irrigated and then they were filled. Next, the teeth were radiographed to verify the quality of the filling. Results The results demonstrated that the teeth treated in a single session, without calcium hydroxide medication, presented 47 canals out of 60 with radiographic evidence of filling, whereas the teeth in which intracanal medication was used, only 07 presented a radiographic image compatible with filling (p < 0.05). Conclusion The use of the calcium hydroxide-based medication Calen made it difficult to obtain a hermetic filling of the root canal system. Clinical significance The clinical significance of this work basing on the fact that once the dentist knowing that property obliteration of calcium hydroxide can be taken care when they are used in the presence of lateral canals.
