• On the basis of above criteria the plaque status was“2” because plaque was observed with the naked eyeand gingival status was given score 1 because mildinflammation was seen.
• Gingival recession was observed on 43
• No mobility of tooth was observed
Clinical findings
• After reviewing the periodontal status it is observed that thereare small pits on the entire surface of maxillary central incisorsalong with the canines (on cusp tips and cuspal slopes) andlateral incisors. But these pits are scattered and are not parallelto the incisal edges.
• These defects are also seen on the 1st molars of both sides inmaxilla. Molars are morphologically altered, brown lines arealso observed especially on the buccal surface.
• When mandibular dentition is observed , Linear defects areseen on the lower central incisors , lateral incisors and canineswhich are parallel to the incisal edges.
• When the inner surfaces of upper and lower arches no defectsare seen
• Clinically there is surface loss of the enamel or pitting of theenamel surface.
• When mandibular molars are observed, both side 1st molarsare involved with same clinical presentation
• Patient has retained deciduous canine in upper 1st quadrant with the absence lateral incisor along with the presence of permanent canine.
• These defects are limited to the enamel only but exposed dentine due to loss of enamel is sensitive.
Investigation
Radiographic feature• Linear radiolucency seen in mandibular anterior teeth from
canine to canine
• It is also seen that in upper first quadrant lateral incisor is congenitally absent
• Multiple circular radiolucency is seen in both the central incisors and upper left lateral incisor and canine
• Small radiolucencies are present especially in enamel regions of left upper and lower 1st molars denoting malformation of enamel
• It is also seen that permanent canine has taken place of permanent lateral incisor because roots are longer and fully formed along with retention of deciduous canine.
• Impacted 3rd molars.
DIFFERENTIAL DIAGNOSIS
• Enamel Hypoplasia
• Molar incisor hypomineralization
•
• Amelogenesis Imperfecta
• Flurosis
• Early decalcification due to caries
Comparison
Enamel Hypoplasia
• Enamel hypoplasia stain relatively clear, and are parallel to the ridge line enamel.
• Enamel hypoplasia can occur in a single tooth or a set of teeth
Dental Fluorosis
• Dental fluorosis as a long-term damage, so the patches were scattered in a cloudy pattern, and not in a well defined pattern
• Dental fluorosis occurs in most teeth, particularly in the maxillary anterior teeth .
J Clin Exp Dent. 2009. Dental fluorosis: Exposure, prevention and management
• Tooth Colour generalized Yellow
• Tooth size Small
• Tooth Shape is also changed
• Enamel leads to attrition which leads to loss of enamel
• Generalized enamel loss
• All the teeth are involved
Comparison B/w Enamel Hypoplasiaand Amelogenesis Imperfecta (clinical)
• Tooth Colour is normal
• Tooth size is normal
• Tooth Shape is normal
• No sign of attrition
• Localized enamel loss
• Involving Incisor canine and molars
• Dark brown bands on gingival part of crown
• No Such thing can be noticed• No Such thing can be noticed• No complain of sensitivity
• Low risk of caries • Not Specific can be generalized or
localized • There is no enamel loss
Comparison B/w Enamel hypoplasiaand Fluorosis (clinical)
• No dark brown stains are seen
• Enamel pitting is seen
• Enamel defects are parallel to the Incisal edge
• Patient complains of sensitivity
• High risk of caries
• Involving Incisor canine and molars
• There is enamel loss
Evidences for ruling out AmelogenesisImperfecta and Fluorosis and making aDiagnosis that this condition is EnamelHypoplasia
Enamel Hypoplasia
• What is Enamel Hypoplasia?
• What are it’s causes?
• What are it’s types?
• How is it classified according to pattern?
• How is it classified
according to severity?
Causes• Exposure to dioxine by prolonged
breast-feeding • Nutritional deficiency [vitamin A,C,D]• Exanthematous diseases• [eg: measles, chicken pox, scarlet
fever]• Congenital syphilis• Hypocalcemia• Birth injury, prematurity, Rh hemolytic
disease• Local infection or trauma• Ingestion of chemicals• Idiopathic causes• Antibiotic used during pregnancy
(Tetracycline)EUROPEAN JOURNAL OF PAEDIATRIC DENTISTRY • 3/2003
Types
• Hereditary
• Environmental
Severity of hypoplasia was recorded according to Schultz (1988):
• 1st degree: mild
• 2nd degree :moderate
• 3rd degree :severe
Pattern of Enamel Hypoplasia
• Linear
• Circular
Variability and Evolution, 2001, Vol. 9: 7587
MILD HEREDITARY TYPE WITH MIXED PATTERN (CIRCULAR AND LINEAR BOTH)
ETIOLOGY CAN BE CONTRIBUTED TOPRE-NATAL USE OF ANTIBIOTICS (TETRACYCLINES)
DIAGNOSIS (CONTINUED)
TREATMENT PLAN (initial)
• Oral hygiene instructions
• Diet modification
• Fluoridated tooth paste and mouth wash
• Topical fluoride application
• Ultrasonic Scaling
•
• Direct composite restoration of :
1,2,33,2,1
3,2,1 1,2,3
Treatment options
• Bleaching
• Microabrasion
• Composite resin
• Porcelain Veneers
• Zirconia crown
Bleaching and microabrasion
• Ashkinazi et al. demonstrated the use of microabrasion technique in patients with enamel hypoplasia. At four-year follow up they showed that the improvements in aesthetics were maintained.
BRITISH DENTAL JOURNAL VOLUME 215 NO. 9 NOV 9 2013
• Enamel which is easily penetrated with an explorer is not a good candidate for microabrasion. Superficial brown and white discolorations on hypomaturated enamel can be easily removed by microabrasion.
Braz J Oral Sci. January-March 2006 - Vol. 5 - Number 16
• When the enamel is intact but discolored, bleaching and/or microabrasion may be used to enhance the appearance
• Clinical guidelines – AMERICAN ACADEMY OF PEDIATRIC DENTISTRY 2013
Composite resin
• Despite the lack of good evidence, due to its reversible and minimally invasive nature, rehabilitation with composite
resins should be considered as the first line of treatment.BRITISH DENTAL JOURNAL VOLUME 215 NO. 9 NOV 9 2013
• Indirect resin composite restorations have shown promising success rates. One study showed a 93% success rate of indirect composite restorations on premolars and molars over a three-year period
BRITISH DENTAL JOURNAL VOLUME 215 NO. 9 NOV 9 2013
Porcelain Veneers
• When restoring teeth affected by MIH with either composite or porcelain veneers, some of the underlying tooth structure may be relatively dark and the translucent nature of these restorations is often unable to adequately mask the discolouration. This can result in poor aesthetics of the restored teeth.
BRITISH DENTAL JOURNAL VOLUME 215 NO. 9 NOV 9 2013
Full coverage restorations
• Some authors have been described the use of all-ceramic crowns as a possible restorative approach particularly in the hypoplastic form - chipping is reported to be a major complication associated with the use of all-ceramic materials, especially zirconia
The Journal of Contemporary Dental Practice, March-April
2013;14(2):320-326
• Porcelain fused to metal crown for posterior teeth and all ceramic crowns for anterior teeth.
The Journal of Contemporary Dental Pracitice, Volume 8, No.4, May 1,2007
• If the enamel or dentin cannot be bonded, full coverage restorations will be required
Clinical guidelines – AMERICAN ACADEMY OF PEDIATRIC DENTISTRY 2013
Final treatment plan was done according to severity
Mild hypoplasia can be treated by direct composite restoration.
1. In the First step, the composite shade selection is done which is A1 Enamel.
2. In the 2nd step little preparation is done of all the defects with round bur creating a bevel in the defects.
3. Adequate isolation is needed so rubber dam is placed, quadrant isolation is done from 1st premolar to 1st
premolar of both the arches4. Then the basic steps of restorations is followed5. Then rubber dam is removed6. Then finishing of the composite is done
Quadrant isolation is done from 1st
premolar to 1st premolar
Composite Restoration placed but not finished
Rubber dam removed and After finishing
