Abstract Lateral luxation injuries are one of the most severe periodontal injuries in dental trauma. The correct diagnosis followed by repositioning of the tooth on the right position is fundamental for the periodontal ligament healing. This study reported a clinical case of lateral luxation of maxillary central incisor involving a new cone beam computed tomography (CBCT) software for reconstruction (e-Vol DX) to confirm the lateral luxation after no conclusive dental trauma injury definition by using conventional exam. The lateral luxation injury was digitally reduced by insertion of tooth back to its alveolus, and at the same session, the tooth was stabilized with a rigid splint and further changed to a semi-rigid nylon splint. During the pulpal status monitoring, the pulp was diagnosed necrotic, then the root canal was treated to prevent root resorption. External office-bleaching and restorative procedure was performed. The 4-years follow up and new imaging exam and digital reconstruction confirmed bone healing and no complication. CBCT images analyzed by eVol DX can be used to determine and to guide lateral luxation treatment.

Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects the alveolar process without compromising the teeth’ pulp vitality is usually asymptomatic, and bone expansion, cortical disruption, and root resorption are uncommon. Due to its avascular characteristic, surgical procedures are often contraindicated. In this case, a 59-year-old female patient presented with a complaint of pain in the right maxillary central incisor. Panoramic and periapical radiographs showed florid cemento-osseous dysplasia in some regions. The right maxillary central incisor showed an extensive radiolucent image suggestive of root resorption but without fibro- -osseous lesion. For better evaluation and implant planning, CBCT was performed and demonstrated florid cemento-osseous dysplasia adjacent to the right maxillary central incisor, contraindicating implant placement. In other regions, CBCT enabled the identification of the expansive features of this fibro-osseous lesion.

Intrusive luxation is a kind of traumatic injury characterized by an axial displacement of the tooth toward the alveolar bone. Its main causes are bicycle accidents, sports/recreational activities, and falls or collisions. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning and repositioning through dental traction by orthodontic devices. The correct diagnosis must be based on clinical and radiographic exams and it is crucial for decision-making in the treatment of injured patients. Currently, the cone beam computed tomography (CBCT) has been widely used in orthodontics, restorative dentistry and implantology as well as in the diagnosis of complex dental trauma. This article reports a case of severe dental intrusion, in which the cone beam computed tomography (CBCT) was performed because of doubts generated after clinical examination and panoramic radiograph analyze. This case report confirmed that the CBCT is an important exam to correct diagnostic.

Abstract Background The proximity of the maxillary sinus floor to the maxillary molar roots increases the probability of oroantral communication on conducting any surgical or endodontic procedure in the involved area. The aim of this study is to evaluate the relationship between each maxillary molar root and maxillary sinus floor using cone beam computed tomography. Predicting the probability of protrusion of each root into the sinus will consequently predict the probability of occurrence of the oroantral fistula in a sample of the Egyptian population. Results The total number of roots located outside the sinus was 121 (35.3%), while those contacting the sinus floor were 80 (23.3%) and those intruded the sinus were 141 (41.2%). The percentage of root intrusion into the sinus in males (56.9%) was significantly (p = 0.01) higher than females (42.9%). The probability of root intrusion in the left molars (54.2%) was non-significantly (p = 0.067) higher than that of the right side (44.3%). As for the type of tooth, the second molar showed the highest probability of root intrusion into the sinus (55.3%) followed by the third molars (52.6%) then the first molars (40.9). According to the type of root, the mesiobuccal root showed the highest probability of intrusion into the sinus (50.9%) followed by the palatal root (49.1%) then the distobuccal root (47.4%). However, the difference in both type of tooth and type of root was statistically non-significant (p = 0.051 and 0.869 respectively). As for the individual root with the highest probability of intrusion, the mesio-buccal root of the right third molar is the most frequent root to intrude the sinus (71.4%) and the mesio-buccal root of the right first molar is the least frequent (22.7%). Conclusions In a sample of the Egyptian population, males exhibit higher probability of root protrusion into the sinus than females. The side and type of tooth are of higher impact on the probability of its intrusion into the sinus compared to the type of root. Left second molars are at a higher risk of oroantral communications on surgical or endodontic procedures compared to other molars due to its highest probability of intrusion into the sinus.

Radiographic Interpretation

A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to make a differential diagnosis and also show that the use of this technology can provide relevant information on the location and nature of root resorption, which conventional radiographs cannot. As a result, the root canal treatment was not initially considered. The patients will be monitored and will undergo a scan after a short period of time to detect any small changes. It was observed that both cases benefited from CBCT in the diagnosis of ICR, because this imaging modality determined the real extent of resorption and possible points of communication with the periodontal space.

Inflammation of the pulp is most common and difficult to diagnose. For it radiographs is necessary. One attempt to do is to assess its histogram and density. Radiography equipment that has the ability to analyze is cone beam computedtomography (CBCT). The purpose of this study is to analyze radiograph of the pulp chamber histogram: peak value,grayscale and trends, as well as the density on the condition reversible and irreversible pulpitis condition. The populationof this descriptive study is secondary data of CBCT-3D radiographs during 2012-2013. Selected sample of 75 data isreversible pulpitis, irreversible pulpitis 80 data, as well as 20 normal condition data as control. Data were analyzed byone way ANOVAand are presented in tables and graphs. The results showed that the value of the histogram under normalconditions showeda different significance for both the peak value of the reversible or irreversible pulpitis (p= 0.01). It isdifferent with a grayscale value, showed no significant different between normal with reversible pulpitis (p =0.997) and significantly different between normal and pulpitis reversible against pulpitis irrebversible (p= 0.03-0.01). There is a growing trend change is on the right direction of reversible and irreversible pulpitis. It was concluded that the irreversiblepulpitis, density and histogram shows the direction of more luscent compared with normal and reversible pulpitisconditions.

Objective: This study sought to assess the frequency and severity of second molar external root resorption (ERR) due to the adjacent third molar and its correlation with the position of third molar and other related factors using cone-beam computed tomography (CBCT). Materials and Methods: This cross-sectional study evaluated 320 second molars and their adjacent impacted third molars on CBCT scans of patients over 16 years, retrieved from the archives of Azad University Radiology Department. Presence/absence of second molar ERR, its location and severity (if present), and position of adjacent third molar were determined on CBCT scans, and recorded in a checklist. Data were analyzed using a logistic regression model. Results: The frequency of second molar ERR was 33.4% in the mandible and 14% in the maxilla. The severity of ERR was significantly correlated with the involved jaw (P=0.001) but had no correlation with age, gender, or depth of impaction of adjacent third molar (P>0.05). The mesioangular and horizontal positions of impacted third molars had a significant correlation with the frequency of second molar ERR (P<0.006). Conclusion: According to the results of this study, ERR occurring in second molars adjacent to third molars is common, especially in the mandible. Mesially inclined third molars have a greater potential of being associated with ERR in second molars.
