LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Kloehn facebow can be used in suitable cases where
maxillary prognathism exists or mesial molar movement has
occurred. The facebow is indicated in early mixed dentition
when permanent maxillary first molars have erupted and can
be banded.
4. Occlusal and craniofacial findings of class II
malocclusion during late mixed/permanent dentition stage
• A child with class II malocclusion presents with a
protrusive mid-face and/or a retrusive chin. They often
report with complaints of superior protrusion, front teeth
jutting out or showing too much.

causes rotation of the palatal plane and slight increase in
SN-PP angle. The inferior descent or extrusion of upper
molars is essentially prevented by the forces of occlusion
from the masticatory muscles.
13. Kloehn (1953) was the earliest advocate of the use of
orthopaedic forces to change positions of teeth and so
influence the changes of the alveolar process in the maxilla.
During normal craniofacial and alveolar growth, alveolus
and teeth move forward and this can be intercepted. Thus
if the maxilla is restrained in class II patients, mandible will
follow its normal growth and reach to a normal relation with
the maxilla.

first molar crowns and prevent their extrusion
The inner bow is expanded, 8 to 10 mm larger than distance
between first molar tubes, and made parallel to the occlusal

The ends of inner bows are bent inwards to prevent the
rotation of the first molars in their position.

Grow normally. The distalizing effect on maxillary molars
causes them to erupt backward and downward, thus inhibit

19. Transverse width of the maxilla improves from the
expanded inner bow, and allows an anterior displacement of
mandible and hence, improvement in the facial convexity.
The maxillary protrusion is reduced while sagittal position
of the mandible improves, which is measured as a reduction
in angleANB. The improvement in craniofacial skeletal and
dental profile is sustained during the period of fixed

Class II division 1 malocclusion:
features and early intervention of
growing maxillary excess
22. Prevalence of malocclusion of class 2
malocclusion.
Cephalometric finding.
Clinical findings.
Interception of growing class2 division 1
malocclusion.
OVERVIEW
23. Class 2 malocclusion comprises agroup of specific
skeletal. Dental and facial features. It is second in
frequency. Distribution and prevalence amongAngle’s
malocclusion classes .
It is the most frequently encountered and treated
malocclusion in orthodontic practice
24. Class 2 malocclusion is a synonym with distal position of
the lower molar or mandible or protrusion of the maxilla
and maxillary teeth or a variable combination
25. Prevalence
The prevalence of Angle’s class 2 malocclusion varies
among population groups.. It is high among caucasians
and lowest among the primitive races..
Class 2 malocclusions are observed in a wide – spectrum
of presentation and severity …
27. Clinical findings
Presentation during deciduous and early mixed
dentition..
• Adistal step relationship 2nd deciduous molars is an
indication of a devoloping class 2 malocclusion during
the mixed dentition ..
Mixed dentition Permanent dentition
28. Occlusal and craniofacial characteristics from
deciduous to mixed dentition
• Distal terminal plane of second deciduous molars . Large
over jet and overbite .
• Narrow maxillary basal bone
• Poor or no spacing in the deciduous dentition
• Transverse discrepancy ( TD) between maxillary and
mandibular deciduous intermolar withs (2.8-1.1) mm
compared to nil among normal occlusal groups .
• Retruded mandible and shorter mandibular length ( Co-Pg)
on cephalometric examination
• The maxilla can also displaced forward in class || subjects
with or without difference in the mandible ..
29. Occlusal and craniofacial characteristics from
deciduous to mixed dentition
• It has been stated by Bishara et al that a distal step deciduous
molar relationship is never self - correcting in growing
children.
• Children with straight terminal plane may develop into a class |
molar or class || molar relationship influenced by the
mandibular growth pattern and adjustment of occlusion during
the late mixed dentition .that would in clinical sense .
• Infer that when we encounter a class|| distal molar relation
early in the mixed or permanent dentition.
• Some sort of interceptive measures may have to be undertaken
or planned because nature would not take care
30. • During transition from deciduous to mixed dentition ,the
craniofacial skeletal patteren shows an abnormal and
variable patteren of growth in class || children compared
to the control group of normal occlusion .
• The upper jaw becomes more prominent due to larger
increments of maxillary protrusion relative to stable basal
cranial structures .
• The mandible grows at a lesser pace than children with
normal occlusion.
• A more backward and downward inclination of the
mandibular body leading to a lesser decrease in the facial
angle is seen .
31. • All this is coupled with a narrow maxillary base in the
development of class || malocclusion .
• Other variations in class || subjects consist of contraction
of the maxilla at both the skeletal and dentoalveolar levels
and narrowing of the base of the nose.
• In general , the occlusal and skeletal features of class ||
malocclusion may remain stable or worsen to the stage of
mixed dentition . There are certainly no favourable
changes into a class | occlusion ..
32. This is often accompanied by a large overjet,
deep bite (open bite can be seen in some) and a
class II (distal) molar, premolar and canine
relationship.

33. The etiology may be attributed to mouth
breathing/prolonged thumb sucking which can be
elicited on carefully recording the history of the
patient….

34. The underlying craniofacial pattern of class II children has
been extensively investigated. Most of the studies have
concentrated on angular, sagittal and vertical
measurements on lateral cephalograms. A few studies are
also available ontransverse dimensions using PA
cephalograms.

35. McNamara5 observed two types of skeletal
combinationsin class II children. He found
mandibular retrusion thesingle most
characteristic feature which was attributed
toenvironmental factors such as :
abnormal muscle
function which
altered occlusal
interdigitations.
36. The skeletal maxillary protrusion was not the major finding.
But was rather neutral.
The 2nd was a combination of maxillary and mandibular
skeletal retrusion, often in association with altered mode of
respiration, i.e. mouth breathing.
These children with maxillary and mandibular retrusion
showed :
Greater vertical

39. Restoration of carious teeth to their correct antero posterior
dimensions is absolutely essential especially proximal
carious lesions on deciduous molars.
The sole purpose is that permanent first molars should
occupy the space distal to 2nd deciduous molars and
should not prematurely migrate forward.

40. Habits. Non-nutritive sucking habits such as prolonged
thumb and finger sucking are taken care of with appropriate
counselling and interceptive habit breaking appliance.A
child with recurrent throat infection, nasal blockages or
allergies should have ENT consultation to prevent mouth
breathing.

41. Orthodontic interventions in class II
malocclusion during mixed dentition..
1- Cases involving essentially maxillary excess compared
to the mandible.
2 - Cases involving essentially mandibular retrusion .
42. Cases involving essentially maxillary excess compared to
the mandible. Involve guiding alveolar growth in class II
division 1 using headgear orthopaedic force.
Used in class 2 with open bite
cases to intrude molars
Used in class 2 with deep bite
cases to extrude molars
43. Acervical headgear with
a face bow is used to
restrain maxillary growth
and distalize the upper
dentition to
class I dentition.
44. Components of a face bow
Kloehn cervical facebow consists of an inner bow of 0.045"
diameter and an outer bow of 0.071" diameter. The inner
bow fits in the round headgear tube on the first molar
bands. Conventionally, a double buccal tube is welded and
soldered on to the maxillary first molar bands..
The inner face bow fits in the headgear tube on
first molar bands
Inner and outer facebow
45.
46. Filho et al8 recommended the onset of treatment
in the late mixed dentition or beginning of the permanent
dentition based on the belief that it often coincides with the
facial growth spurt. It may also have the advantage of
continuing the treatment with full-banded fixed appliance,
following completion of 12 months of the first phase.
47. cervical traction is continued during/or till the end of
activeclinical crown height. The purpose is to place it close
to centre of resistance of the first molar which is near the
trifurcation of the roots. The inner bow has stops against
molar tubes and are so adjusted that a space of 4-6 mm is
kept between the bow and incisors. The stops can be either
soldered or bent..
48. The outer face bow is extended to the tragus of the ear.
The rigid outer bow is maintained at an elevation of about
treatment to prevent relapse and enhance anchorage for
maxillary anterior retraction/overjet correction
49.
50. Adverse effects
Unwanted side effects of Kloehn headgear can result from
the use of this method of treatment in high angle cases,
where molar extrusion and distal tipping may be significant.
This coupled with unfavourable growth of mandible and
clockwise rotation may bring about an undesirable outcome.
The success of the treatment is fully compliance dependent.
The appliance, if not worn correctly or in case of loose
molar band, breakage or welding failure of buccal tube(s),
may cause injury of various kinds and severity.
51. Long-term effects
The long-term effects of early headgear treatment on 8-year
follow-up have shown that headgear treatment shows a
significant reduction in number of extraction treatment as
compared to controls. The appliance inhibits the growth of
the maxilla and results in wider and longer arches. Its main
effect on maxilla is on the orientation of the maxillary plane.
The maxillary arch expansion achieved during early headgear
treatment results in a corresponding wide lower arch as an
adaptation to maxillary arch..
The arch expansion has been found to be maintained during
long-term follow-up
52.
53. Summary
The forward growing maxilla can be intercepted during
mixed dentition utilising orthopaedic forces in right
direction and amount with Kloehn face bow
This modality of treatment was once very popular
especially in USA. The appliance is effective however
requires patient compliance..
