  • 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.

  • 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.

Bidlack 1,2,* 1 The Forsyth Institute, Cambridge, MA 02142, USA 2 Department of Developmental Biology, Harvard School of Dental Medicine, Boston, MA 02115, USA * Correspondence: [email protected] (A.G.-B.); [email protected] (F.B.B.) Received: 26 May 2020; Accepted: 20 June 2020; Published: 23 June 2020 Abstract: Tooth enamel is the outer covering of tooth crowns, the hardest material in the mammalian body, yet fracture resistant. The extremely high content of 95 wt% calcium phosphate in healthy adult teeth is achieved through mineralization of a proteinaceous matrix that changes in abundance and composition. Enamel-specific proteins and proteases are known to be critical for proper enamel formation. Recent proteomics analyses revealed many other proteins with their roles in enamel formation yet to be unraveled. Although the exact protein composition of healthy tooth enamel is still unknown, it is apparent that compromised enamel deviates in amount and composition of its organic material. Why these differences affect both the mineralization process before tooth eruption and the properties of erupted teeth will become apparent as proteomics protocols are adjusted to the variability between species, tooth size, sample size and ephemeral organic content of forming teeth. This review summarizes the current knowledge and published proteomics data of healthy and diseased tooth enamel, including advancements in forensic applications and disease models in animals. A summary and discussion of the status quo highlights how recent proteomics findings advance our understating of the complexity and temporal changes of extracellular matrix composition during tooth enamel formation.

  • 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.

It is believed that this cusp is seen in people with larger teeth. Since it has different prevalence among populations, it can be used in forensic dentistry. As well, dentists should be aware of common dental anomalies that might impact dental treatments. In this study, the prevalence of Carabelli cusp and its relation to tooth size in permanent and deciduous dentitions in Iranian population was assessed.

  • Tooth Decay Information
    ToothMasters Information on Tooth Decay Definition: Tooth decay is the destruction of the enamel (outer surface) of a tooth. Tooth decay is also known as dental cavities or dental caries. Decay is caused by bacteria that collect on tooth enamel. The bacteria live in a sticky, white film called plaque (pronounced PLAK). Bacteria obtain their food from sugar and starch in a person's diet. When they eat those foods, the bacteria create an acid that attacks tooth enamel and causes decay. Tooth decay is the second most common health problem after the common cold (see common cold entry). By some estimates, more than 90 percent of people in the United States have at least one cavity; about 75 percent of people get their first cavity by the age of five. Description: Anyone can get tooth decay. However, children and the elderly are the two groups at highest risk. Other high-risk groups include people who eat a lot of starch and sugary foods; people who live in areas without fluoridated water (water with fluoride added to it); and people who already have other tooth problems. Tooth decay is also often a problem in young babies. If a baby is given a bottle containing a sweet liquid before going to bed, or if parents soak the baby's pacifier in sugar, honey, or another sweet substance, bacteria may grow on the baby's teeth and cause tooth decay. Causes: Tooth decay occurs when three factors are present: bacteria, sugar, and a weak tooth surface. The sugar often comes from sweet foods such as sugar or honey.

  • 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.

  • 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.
