    Abstract: Background: Isolated zygomatic arch fractures, managed by closed methods, can be inadequate leading to facial asymmetry. Assessment of the reduction and ensuring correct alignment of frac­tured fragments in the operation table always avoids next surgery. This study aims to determine intraoperative, adequacy of reduction of by use of ultrasound in isolated zygomatic arch fracture. Methods: During the closed reduction of isolated zygomatic arch linear probe of ultrasound was used to check the continuity of the echogenic line. The intraoperative ultrasound finding was com­pared with the gold standard CT scan. Results: Ultrasound has 100% sensitivity and 80 % specificity. It also has high precision and accu­racy to determine the reduction of the fractured bone. Conclusions: Ultrasound is a handy tool in the reduction of zygomatic arch fracture. It not only shows but also guides to adequate reduction.

    Abstract: Background: Mandibular third molar’s roots have close proximity to the inferior alveolar canal (IAC) and nerve. Inferior alveolar nerve injuries have been observed to occur more frequently when there is radiographic evidence of close contact of third molar roots to the IAC. Orthopan­tomogram is one of the commonly used diagnostic tools for evaluating the relationship between these two structures. There is lack of data regarding prevalence of these radiographic signs in Nepalese population. It was required to assess the reliability on the radiographic signs of relation­ship between the IAC and the third molar roots, to establish IAC as risk indicators for IAC exposure during extraction. Methods: A single centre cross-sectional descriptive study was designed where demographic data and radiographic signs of third molar roots proximity to IAC were obtained from imaging software records and descriptive analysis was performed with SPSS version 20. Results: One or more radiographic signs were observed in 49.6% of mandibular third molars. In­terruption of white line followed by narrowing of canal and darkening of roots was observed in decreasing order of frequency and no statistically significant association between sex, age and side of impacted third molar with presence of radiographic signs. Conclusions: Presence of one or more radiographic signs of proximity of mandibular third molar roots with IAC in nearly half of the cases. Clinicians should be aware of risk of nerve injury on pres­ence of these signs. Further investigation with cone beam computed tomography to rule out any nerve injury risk should be adopted into practice.

    Abstract: Mandibular step body osteotomy has been out of favour since more stable ramus osteotomies were refined and used for jaw deformities. Mandibular body osteotomy still has certain indications for which it is preferable over ramus osteotomies. Mandibular body osteotomy is best suited to correct prognathism caused by mandibular body excess with a retained tooth or in presence of extraction space, with good posterior occlusion, when ramus osteotomies and setback will lead to loss of the last tooth and non-obtuse gonial angle. Other indications are apertognathia, mandibu­lar asymmetry and small advancements of the anterior mandible. Here we present a case 24 year male with a skeletal class III malocclusion managed with an intra­oral mandibular step osteotomy and setback of 8 mm. One-year followup has shown minimum neurosensory and odontogenic complications associated with mandibular step osteotomy and very high satisfaction among the patient. We also present a brief review of the indications, modifi­cations and refinement of the technique and summarize current published clinical usage. This is a very stable osteotomy with favourable fracture pattern and does not involve stripping or change in position of muscles of mastication thereby ensures long term stability and minimal risk of relapse. This surgery also has minimal effect on airway narrowing compared to the ramus osteotomy setback. For some specific indications not suited to a sagittal split ramus osteotomy, mandibular body step osteotomy still has relevance and usage.

    Abstract: Background: Cervical abrasion is defined as the loss of tooth substance that occurs in the absence of carious mechanism at cementoenamel junction of a tooth. This type of lesion can cause discommoding effects in dental health. The aim of the study was to assess the prevalence of cervical abrasion among general population in Chitwan and to relate the find­ing to probable etiology, thereby developing an etiological hypothesis that can be beneficial during treatment. Methods: The study was carried out between August 2019 and October 2019 in 500 adults who attended the department of Conservative Dentistry and Endodontics, COMS-TH. A proforma con­sisting of demographic data, type of di et and oral hygiene practices was used for the data col­lection and each patient went through a clinical examination as well. The statistical analysis was performed using SPSS. Descriptive analysis was performed and Chi-square test of association was done. Results: Total prevalence of cervical abrasion in the study population was 10.4%. A statistically sig­nificant relationship was observed between cervical abrasion, gender, age, toothbrush frequency, method of tooth brushing and type of toothbrush employed. The study affirmed that population with cervical abrasion had hypersensitivity. Conclusions: The prevalence of cervical abrasions was seen to increase with age, frequency of toothbrushing, faulty method of toothbrushing and use of inappropriate type of toothbrush. Hence, it is advocated that dental professionals guide people on correct brushing technique and use of appropriate type of toothbrush to avoid and prevent this problem from worsening.
