Occlusal Examination
12. Plaque and Gingival index
A film of plaque adhering to the free gingival margin and
adjacent area of the tooth, which can not be seen with
the naked eye. But only by using disclosing solution or by
using probe
No plaque
Moderate accumulation of deposits within the gingival
pocket, on the gingival margin and/ or adjacent tooth
surface, which can be seen with the naked eye
Abundance of soft matter within the gingival pocket
and/or on the tooth and gingival margin.
No inflammation
Mild inflammation, slight change in color, slight
edema, no bleeding on probing.
Moderate inflammation, moderate glazing, redness,
bleeding on probing
Severe inflammation, marked redness and
hypertrophy, ulceration, tendency to spontaneous
bleeding

13. • On the basis of above criteria the plaque status was
“2” because plaque was observed with the naked eye
and gingival status was given score 1 because mild
inflammation was seen.
• No mobility of tooth was observed
18. • Canine to canine can be seen easily
• Part of mid-incisal area of lower mandibular
teeth can be seen
• Patient gums are also seen which make it a
gummy smile.
• Central incisors are prominent
19. Clinical findings
• In maxillary arch ,spacing is seen in Maxillary
central incisors
• Space is also present between central incisors
and lateral incisors as well but this space is
smaller than central incisors
• Space is also observed between lateral incisors
and canine as well, which is very large and
cannot be closed by restoration. Orthodontic
intervention is mandatory for closing this
space.
21. • Right central Incisor is labially placed to the
arch form
• Spacing is also observed in the right canine
and premolar as well
• Palate is shallow
• Maxillary arch is large.
• No spacing is observed in Mandibular arch.
23. Comparison between distal crown
inclination & diastema
• Crowding is not observed
• Both the centrals are
separated with each other
• No inclination is observed
• Crowding Is observed
• Both the centrals are in
contact at the cervical area of
the crown
• Distal inclination is observed
24. • Lateral incisors are
present
• Lateral incisors are
congenitally absent
Comparison between Congenitally
missing teeth & diastema
25. • Peg shaped laterals are
observed
• Mal-aligned teeth are
observed
Comparison between Peg-shaped
laterals & diastema
• No Peg shaped laterals
are observed
• No Mal-aligned teeth
are observed
27. Causes of midline diastema
• Genetics
• Superior labial frenum
• Anterior traumatic bite
• Oral habits
• Supernumerary teeth
• Tooth and arch size discrepancy
• Pathologic migration of teeth
• Odontomas occuring in the maxillary midline
• Developmental cyst in the oro-facial midline
• Flaccid lips
Bishara SE, Jakobsen JR. Individual variation in tooth size-arch length. World J Orthod 2006
28. Etiology of my case
Tooth and Arch Size Discrepancy
because all the teeth are of normal size and
spacing is also observed generally.
Lamberton CM, Reichart PA, Triratananimit. Tooth size-arch length changes
from the primary to permanent dentitions. World J Orthod 2009
29. Measurements and Investigation
• Length and width of right central incisors = 9mm
• Length and width of right central incisors = 9mm
• Length and width of right central incisors = 7mm
30. Midline space
• Space between central incisors are seen which was
measured and found to be 1.5mm
35. Prediction of the fate of midline
diastema
• It claimed to have an accuracy of 88%
Sanin’s prediction is as follows:
Space between mixed dentition Possibility of space closure
1mm 99%
1.5mm 85%
1.85mm 50%
2.7mm 1% ( Treatment either ortho or
restorative approach is
mandatory)
Dent Update 2014; 41: 457–464
36. Treatment options
• Different treatment modalities include
restoration, orthodontics, prosthodontics,
surgery, and various combinations
• Direct composite restoration
• Orthodontic and porcelain laminate
placement
• Orthodontic procedures

37. Classifying Diastema according to
treatment Plan
Diastema Size Treatment
Mild 1mm or less Direct composite( with
enamel shade only)
Moderate More than 1mm but less
than 2.5 mm
Direct composite
restoration ( with enamel
along with dentine shade is
used)
Severe size More than 2.5 mm Direct veneering +
orthodontic movement
Summit’s fundamental of Operative Dentistry 4th edition
38. Treatment Plan of my Case
• According to the above table, my case falls in
moderate category of midline diastema. So the
final treatment plan will be direct composite
restoration ( enamel + dentine shade are used)
39. Final treatment plan was done
according to severity
Midline Diastema can be closed by direct
composite restoration.
1. First the Diagnostic wax-up is made in order to
judge the favourable outcome. So wax is added to
the distal surface of right and left central incisor.
2. In the First step, the composite shade selection is
done which is A2 Enamel and Dentine.
3. No preparation is done.
40. 4. Adequate isolation is needed so rubber dam is
placed, quadrant isolation is done from 1st
premolar to 1st premolar of both the arches
5. Then the basic steps of restorations is followed
6. Then rubber dam is removed
7. Then finishing of the composite is done
47. Problems
• Both the incisors get more prominent due to
increase in size
• Shade selection was not that adequate
• Normal squarish shape of both the incisors is
not followed
