RESUMEN

The present study is a systematic review of the evaluation of screening programs as a strategy for early detection of oral cancer. The aim of this study was to assess whether screening through visual inspection is able to identify injuries in early stages, to increase survival, and to decrease the incidence and mortality of oral cancer. Studies using visual inspection to screen for oral cancer and potentially malignant lesions in apparently healthy individuals over 18 years without previous diagnosis of the disease were included. The MEDLINE/PubMed, Cochrane databases Library, EMBASE, and LILACS, including manual search and gray literature, were searched through January 2021 with no language or date restrictions. The risk of bias and the methodological quality were evaluated according to the appropriate tool for each study design. The analysis of the results was narrative. Seventeen studies were reviewed that included cohort, accuracy, and randomized clinical trial studies. The tracking type performed was opportunistic and organized in a variety of environments. The age of participants ranged between 18 and 60 years old and, in some programs, only people with risk habits for oral cancer were included. The screeners were healthcare professionals, physicians, and dentists. Two studies reported data on the incidence rate of severe cases and mortality and showed a reduction when patients were at risk for the disease and participated in the program more than once. A limitation of this review was the great variability observed in the estimates of the screening effectiveness among the studies, which made comparisons difficult. If a screening program is continuous and able to ensure the inclusion of high-risk individuals, it can contribute to improvement in survival rates with a change of stage and can have a significant impact on incidence and mortality due to the disease.

RESUMEN

Rationale: Multiple Calcifying Hyperplastic Dental Follicle (MCHDF) is an extremely rare condition and is characterised by multiple impacted permanent teeth, with enlarged dental follicles, containing calcifications. Cone-beam computed tomography (CBCT) is the ideal exam for the identification of this condition. Patient Concerns: The present study seeks to compare the behaviour of MCHDF in imaging exams of three clinical cases with their MCHDF imaging diagnoses, in which a change about tooth eruption was observed. Diagnosis: CBCT proved to be an important diagnostic tool for MCHDF, as it is able to identify these small calcifications, as well as measure the size of the follicle.Treatment Outcomes and Take. Away Lessons: With a consistent imaging diagnosis, less invasive treatments become a viable option for this condition, since functional and aesthetic involvement is common in these patients, who often tend to be quite young.

RESUMEN

PURPOSE: The coronectomy technique is an alternative to conventional impacted tooth removal which aims to reduce the risk of damage to the inferior alveolar nerve (IAN). The technique is usually performed by senior oral surgeons or residents in training. Herein, patients were treated in a single service, in which coronectomy was performed by an undergraduate dental student on partially erupted lower third molars. METHODS: A prospective analysis was performed on 21 individuals submitted to a total of 35 coronectomies. Clinical and radiographic follow-up was performed for at least 12 months. RESULTS: Overall, healing was within normal limits, without major complications and without permanent IAN injury. However, one case showed temporary IAN paraesthesia resolved within a month and two required repetitions of coronectomy due to the remaining enamel, but with a good final result. Root migration was observed in all cases, but no other surgery was required. CONCLUSION: Coronectomy may be an important option for treating partially erupted teeth in close nerve relationships, which could also be performed by trained undergraduate dental students. This series is interesting because it can encourage oral and maxillofacial surgeons to train undergraduate students and to stimulate their attraction and passion for surgery.

RESUMEN

The aim of this study was to describe a series with 66 cases of infected cemento-osseous dysplasia (COD) and to discuss the demographic distribution, clinicoradiographic features and treatment of this condition. A study looking back on the diagnoses made at a single Brazilian centre within a 28-year timeframe was performed. A literature review with searches across five databases was also conducted to identify reports on osteomyelitis/infected COD. Descriptive and statistical analyses were performed. The case series study showed a female/male ratio of 21:1. Affected individuals' mean age was 57.4 years. Mandible was the most affected site (95.5%) and florid subtype was the most frequent infected COD (62.1%). Tooth extraction was the main factor associated with the development of infection associated within a COD lesion. The literature review retrieved 30 studies reporting 46 cases of this condition. Asian women in their 40 s and 50 s were more affected. Surgery for removal/curettage of necrotic bone was acknowledged as an appropriate approach to the treatment of this infection. The clinicodemographic data of the study were similar to data collected across the literature. Clinicians, maxillofacial surgeons and oral rehabilitation providers should be alert to the diagnosis of COD, since infection is a frequent complication whose management is challenging.

RESUMEN

Taurodontism is considered a dental anomaly responsible for a morphoanatomical change in the shape of the tooth in which the roots are reduced in size but the body of the tooth is enlarged and bulky. The aim of this paper is to present a case of a 25-year-old female patient with taurodontism of mandibular partially erupted third molars, presenting a high risk of angle fracture and paresthesia in case of their removal, treated by means of coronectomy. The postoperative period was uneventful and the patient remained in follow-up for 12 months. In conclusion, the identification of third molars with higher risk of complications related to their extractions is the key to consider conservative measures to avoid problems. Coronectomy is a relatively simple technique that should be taken into account when considering bulky, deeply located third molars with a high risk of paresthesia or mandibular fracture, even in presence of taurodontism.
