Abstract

Land cover change is primarily caused by direct land use, which, if carried out without considering conservation measures, can lead to the degradation of watershed quality, resulting in increased sedimentation and erosion with low infiltration rates. This study aims to examine land cover changes, other factors influencing erosion, and the effect of land cover on erosion in the Suso Watershed in 2018 and 2023 using the Soil and Water Assessment Tool (SWAT) model. The study consists of three stages: 1) Analysis of land cover data for 2018 and 2023 to identify changes in land cover related to erosion hazard; 2) Analysis of other influencing factors such as slope, rainfall, and soil type; and 3) Erosion hazard modeling using SWAT. Land cover change in the Suso Watershed between 2018 and 2023 significantly affected erosion hazard levels. In 2018, the area was predominantly classified under moderate erosion hazard (60–180 tons/ha/year), while in 2023, it shifted to being dominated by the severe erosion hazard category (180–480 tons/ha/year). Other factors contributing significantly to erosion include steep slope conditions (>45%), high annual rainfall (2,700.50–2,759.06 mm in 2018), which increased to a very high category in 2023 (3,062.72–3,157.82 mm), and the predominance of inceptisol soil types. The conversion of forested land to non-forested land, along with other influencing factors, has contributed to the increase in erosion hazard levels in the Suso Watershed.

Abstract

AbstractIntroduction: Ectopic canines are permanent teeth that develop outside of their normal position in the jaw and can be caused by genetic or environmental factors. And require orthodontic treatment to correct it. Objective: This case report involves orthodontic treatment using segmental retraction to correct ectopic maxillary canine. Case Report: A 13-year old girl complained that her canine tooth was above the other teeth in the right maxilla. The maxillary midline shifted to the right by 3 mm. Cephalometrics showed SNA 810, SNB 770, ANB 40, and overjet and overbite were normal. The molar and canine relation on the right side was class II, and the left side was class I. The patient was treated with segmental retraction to correct the position of the maxillary right canine with extraction of the maxillary right first premolar and extraction of the maxillary left premolar to fix the right shifted midline. After 19 months of orthodontic treatment, facial profile changes were achieved (convex to straight tendency), and ectopic maxillary right canine and shifted midline were corrected. Conclusion : Segmental retraction in orthodontic treatment of ectopic canine provides satisfactory results and quick correction for patients and improves occlusion function and aesthetics.

Abstract

Abstract Introduction: The eruption path of the maxillary permanent canine is not only long and winding, but slightly buccal in relation to the dental arch. Moreover, its eruption occurs after that of the lateral incisor and the first premolar. Therefore, any approximation between the roots of these teeth decreases the space available for the canine and may cause their intraosseous retention or ectopic eruption, usually manifested by an exaggerated buccal position. Objective: the aim of this case report was to present the treatment of transposition and ectopic maxillary Case Report: A 15 years-old boy with chief complaint of misaligned teeth. Clinical examination revealed a convex facial profile with a unproportional lower third of the face, diminished nasolabial angle, showed canine displaced while smiling. The presence of the right and left maxillary primary canine was noted, as well as space deficiency in the maxillary arch of approximately —18 mm and severe crowding both of the anterior teeth in maxilla and mandible. Furthermore, the maxillary canines presented virtually superimposed buccal to the maxillary lateral incisors or nearly transposed. The patient was treated with 0.022-in Roth prescription brackets. Extraction of the 14, 24, 35, and 45 to reveal the crowding and corection the transposition and ectopic maxillary canine. Total treatment time was 15 months. On the day of debonding, a maxillary Hawley retainer was delivered Conclusion: Proper treatment of an ectopic canine patient with severe crowding requires careful treatment planning by the orthodontist. The decision to extract the premolars is to be good aesthetically, functionally, and for more stable results in these patients
