Root Canal Treatment of Permanent Mandibular First Molar with Six Root Canals: a Rare Case
CASE REPORT Turk Endod J 2016;1(1):52–54 doi: 10.14744/TEJ.2016.65375 Root canal treatment of permanent mandibular first molar with six root canals: a rare case Ersan Çiçek,1 Neslihan Yılmaz,1 Murat İçen2 1Department of Endodontics, Faculty of Dentistry, Bülent Ecevit University, Zonguldak, Turkey 2Department of Oral Radiology, Faculty of Dentistry, Bülent Ecevit University, Zonguldak, Turkey This case report aims to present the management of a mandibular first molar with six root canals, four in mesial and two in distal root. A 16-year-old male patient who has suffered from localized dull pain in his lower left posterior region for a long time was referred to the endodontic clinic. On clinical examina- tion, neither caries lesion nor restoration was observed on the mandibular molar teeth; but the occlu- sal surface of the teeth had pathologic attrition. The mandibular and maxillary molars were tender to percussion due to bruxism, but there was no tenderness towards palpation. All of the molars revealed normal responses to the vitality tests. It was suggested that he should use the night-guard against brux- ism. After three months, his pain almost completely relieved, but the percussion of the left mandibular molar was still going on. After access cavity preparation, careful examination of the pulp chamber floor with dental loupe and endodontic explorer (DG 16 probe) showed six canal orifices, four of mesially and two of distally. CBCT scan was performed in order to confirm the presence of six canals. Following one year, it was observed that he had no pain. -

Objective: The purpose of this operating microscope. study was to report a clinical case showing a varying number of palatal roots in a second maxillary molar with the aid of operating microscope (OM). Case report: A four-rooted maxillary permanent second molar with 2 separated palatal canals undergone endodontic therapy. After endodontic access, examination of the chamber floor using an operating microscope revealed two distinct palatal canals orifices. A radiograph was taken after the working lengths of each canal were estimated by means of an electronic apex locator which clearly identified the four roots with independent four canals. The canals were instrumented with ProTaper™ rotatory instruments under irrigation with 5% sodium hypochlorite, obturated with Pulp Canal Sealer® and continue wave technique. -
Endodontic Therapy in a 3-Rooted Mandibular First Molar: Importance of a Thorough Radiographic Examination
C LINICAL P RACTICE Endodontic Therapy in a 3-Rooted Mandibular First Molar: Importance of a Thorough Radiographic Examination • Juan J. Segura-Egea, DDS, MD, PhD • • Alicia Jiménez-Pinzón, DDS • • José V. Ríos-Santos, DDS, MD, PhD • Abstract This case report describes endodontic therapy on a mandibular first molar with unusual root morphology. In the initial treatment the working length had been determined with only an apex locator; no periapical radiographs had been obtained because the patient was pregnant. The root canal into an additional distolingual root had not been found and was therefore left untreated, which led to treatment failure after 11 months. The radiographic examina- tion performed in a subsequent endodontic treatment allowed detection of the anomalous root and completion of the root canal treatment. The distolingual root canal would have been identified during the initial endodontic therapy if a thorough radiographic examination had been carried out. This report highlights the importance of radiographic examination and points out the need to look for additional canals and unusual canal morphology associated with a mandibular first molar. Radiographic examination during pregnancy is also discussed.

Tooth Size Proportions Useful in Early Diagnosis
#63 Ortho-Tain, Inc. 1-800-541-6612 Tooth Size Proportions Useful In Early Diagnosis As the permanent incisors begin to erupt starting with the lower central, it becomes helpful to predict the sizes of the other upper and lower adult incisors to determine the required space necessary for straightness. Although there are variations in the mesio-distal widths of the teeth in any individual when proportions are used, the sizes of the unerupted permanent teeth can at least be fairly accurately pre-determined from the mesio-distal measurements obtained from the measurements of already erupted permanent teeth. As the mandibular permanent central breaks tissue, a mesio-distal measurement of the tooth is taken. The size of the lower adult lateral is obtained by adding 0.5 mm.. to the lower central size (see a). (a) Width of lower lateral = m-d width of lower central + 0.5 mm. The sizes of the upper incisors then become important as well. The upper permanent central is 3.25 mm.. wider than the lower central (see b). (b) Size of upper central = m-d width of lower central + 3.25 mm. The size of the upper lateral is 2.0 mm. smaller mesio-distally than the maxillary central (see c), and 1.25 mm. larger than the lower central (see d). (c) Size of upper lateral = m-d width of upper central - 2.0 mm. (d) Size of upper lateral = m-d width of lower central + 1.25 mm. The combined mesio-distal widths of the lower four adult incisors are four times the width of the mandibular central plus 1.0 mm. -
Dental Arch Space Changes Following Premature Loss of Primary First Molars
PEDIATRIC DENTISTRY V 30 / NO 4 JUL / AUG 08 Scientific Article Dental Arch Space Changes Following Premature Loss Of Primary First Molars: A Systematic Review William Tunison, BSc1 • Carlos Flores-Mir, DDS, DSc2 • Hossam ElBadrawy, DDS, MSc3 • Usama Nassar, DDS, MSc4 • Tarek El-Bialy, DDS, MSc OSci, PhD5 Abstract: Purpose: The purpose of this study was to consider the available evidence regarding premature loss of primary molars and the implications for treatment planning. Methods: Electronic database searches were conducted—including published information available until July 2007—for available evidence. A methodological quality assessment was also applied. Results: Although a significant number of published articles had dealt with premature primary molar loss, only 3 studies (including a total combined sample of 80 children) had the minimal methodological quality to be considered for this systematic review. Conclusion: A reported immediate space loss of 1.5 mm per arch side in the mandible and 1 mm in the maxilla—when normal growth changes were considered—was found. The magnitude, however, is not likely to be of clinical significance in most cases. Nevertheless, in cases with incisor and/or lip protrusion or a severe predisposition to arch length deficiency prior to any tooth loss, this amount of loss could have treatment implications.

Root Canal Morphology and Configuration of 123 Maxillary
OPEN International Journal of Oral Science (2017) 9,33–37 www.nature.com/ijos ORIGINAL ARTICLE Root canal morphology and configuration of 123 maxillary second molars by means of micro-CT Thomas Gerhard Wolf1, Frank Paqué2, Anja-Christin Woop1, Brita Willershausen1 and Benjamín Briseño-Marroquín1 The aim of this study was to investigate the root canal configuration, accessory canals and number of main foramina of 123 maxillary second molars by means of micro-computed tomography. The teeth were scanned and reproduced with 3D software imaging. The root canal configuration and number of main foramina were evaluated by means of a four-digit system. The morphological complexity of human maxillary second molars is depicted by the number of accessory and connecting canals. The most frequently observed root canal configurations in the mesiobuccal root were 2-2-2/2 (19.5%), 2-2-1/1 (14.6%) and 2-1-1/1 (13.0%). A 1-1-1/1 configuration was observed in 93.5% and in 96.7% in the distobuccal and palatal roots, respectively. The MB1 root canal had one accessory canal (18.7%), and 8.9% of the MB2 root canal had one or two accessory canals. The distobuccal (11.3%) and palatal (14.6%) root canals had at least one accessory canal, and connecting canals were observed in 16.3% of mesiobuccal roots. The MB1, MB2, distobuccal and palatal root canals had one main foramen in 99.2%, 43.1%, 98.4% and 99.2% of samples, respectively. In the mesiobuccal root, one accessory foramen was detected in 14.6%, two were detected in 7.3%, and three were detected in 5.7%. -
Third Molar (Wisdom) Teeth
Third molar (wisdom) teeth This information leaflet is for patients who may need to have their third molar (wisdom) teeth removed. It explains why they may need to be removed, what is involved and any risks or complications that there may be. Please take the opportunity to read this leaflet before seeing the surgeon for consultation. The surgeon will explain what treatment is required for you and how these issues may affect you. They will also answer any of your questions. What are wisdom teeth? Third molar (wisdom) teeth are the last teeth to erupt into the mouth. People will normally develop four wisdom teeth: two on each side of the mouth, one on the bottom jaw and one on the top jaw. These would normally erupt between the ages of 18-24 years. Some people can develop less than four wisdom teeth and, occasionally, others can develop more than four. A wisdom tooth can fail to erupt properly into the mouth and can become stuck, either under the gum, or as it pushes through the gum – this is referred to as an impacted wisdom tooth. Sometimes the wisdom tooth will not become impacted and will erupt and function normally. Both impacted and non-impacted wisdom teeth can cause problems for people. Some of these problems can cause symptoms such as pain & swelling, however other wisdom teeth may have no symptoms at all but will still cause problems in the mouth. People often develop problems soon after their wisdom teeth erupt but others may not cause problems until later on in life. -

[email protected] Abstract: Although it is a very rare situation, four-rooted maxillary second molars can occur. The existence of two palatal roots is extremely rare and ranges about only 0.4%. The aim of this study is to present and document a very rare anatomic configuration of a four-rooted maxillary second molar. Anatomic variation in the number of roots and root canals can occur in any tooth, although some cases can be extremely rare as the one presented here.Clinicians should be aware of this possibility before considering any kind of treatment. Keywords: Molar, Dental Anatomy, Anatomical Variation 1. INTRODUCTION Usually the maxillary second molars are described in the literature as a teeth that have 3 roots with 3 or 4 root canals. Understanding of the presence of additional roots and unusual root canals is essential and determines the success of endodontic treatment1. The existence of maxillary second molars with 4 roots (2 buccal and 2 palatal) is extremely rare and ranges about only 0.4%.This information comes from a study that showed, after the examination of two different horizontally angled radiographs of 1,000 maxillary second molars, just four with four roots2. -
Two Sets of Teeth in a Lifetime
Two sets of teeth in a lifetime Two sets of teeth in a lifetime Deciduous teeth: They are the first set of teeth we have and there are altogether 20 of them. They usually start to erupt from around the age of six months until 3 years of age. Permanent teeth: At the age of 6, they sequentially erupt to replace the deciduous teeth which become loose and shed. Deciduous teeth: Space retainer for permanent teeth Normally, underneath the root of each deciduous tooth, there is a developing permanent successor tooth. When it is time for the permanent successor tooth to erupt, the root of the deciduous tooth will resorb and the deciduous tooth will become loose. The place is then taken up by its permanent successor tooth. Deciduous tooth retains the space for its permanent successor tooth. No tooth is dispensable If the deciduous tooth, especially the second deciduous molar, is lost early due to tooth decay, the consequences can be serious: Poor alignment of the teeth The second deciduous molar is already lost The first permanent molar Since the first permanent molar erupts behind the second deciduous molar at the age of 6, the space of the lost second deciduous molar will gradually close up as the first permanent molar moves forward. The permanent tooth is crowded out of the arch when it erupts Later, when the second permanent premolar erupts to replace the second deciduous molar, the permanent tooth will either be crowded out of the dental arch or be impacted and is unable to erupt, leading to poor alignment of the teeth. -
A Comparative Study of One Implant Versus Two Replacing a Single Molar Thomas J

Balshi, DDS, FACP/Ramon E. Hernandez, DMD/Maria Claudia Pryszlak, DMD/Bo Rangert, PhD, MechEng A comparative study between one and two Brånemark implants replacing a single molar was conducted. Forty-seven individuals comprised two groups of 22 patients treated with one implant and 25 with two implants. A total of 72 implants were placed, 66 (92%) in the mandible and six (8%) in the maxilla. After the first year of function, the success rate was 99%, with only one implant lost. Between the second- and third-year follow-ups, 100% of the implants continued to function in the remaining 46 patients, giving a 3-year cumulative success rate of 99%. The marginal bone loss between 1 and 3 years of function was 0.10 mm (SD 0.20) for the group with one implant and 0.24 mm (SD 0.20) for the group with two implants. No changes were observed in the Sulcus Bleeding Index during the 3-year follow-up. Prosthesis mobility or screw loosening was the most frequent complication and was predominant in the group using one implant (48%), but was substantially reduced in the group using two implants (8%). These mechanical problems, using one implant only, seem to be preventable using a stronger screw joint (CeraOne abutment). Precise centric occlusal contact was established and maintained over the study period, which was thought to contribute to the very high success rate for the single-implant-supported molars, despite their high degree of mechanical problems. -
