Developmental Anomalies : Van Der Woude Syndrome; Etiology Clinical Features Oral Manifestations and Treatment
van der Woude syndrome is an autosomal dominant syndrome consisting of a cleft lip / cleft palate in association with lower lip pits.
The pits constantly secrete mucous and the discharge is very embarrassing for the patient.
Chromosomal studies show deletions in the chromosomes at 1q32 . A modifying gene may also be responsible which is located at 17p11.
Some extraoral manifestations like limb anomalies, popliteal webs, and brain abnormalities are also reported.
Very rare cases with accessory nipples, congenital heart defects, and Hirschprung disease are also seen.
Surgical removal of pits can be carried out for cosmetic reasons.

Developmental Anomalies : Facial Hemiatrophy Etiology Clinical Features Oral Manifestations Histologic Features and Treatment
Also known as Parry – Romberg Syndrome, Romberg Syndrome or Hemifacial Atrophy.
Trophic malfunction of the cervical sympathetic nervous system
The skin, subcutaneous tissue, muscle and bone show atrophy.
Various cartilages of the face are also involved.
Contralateral Jacksonian epilepsy, trigeminal neuralgia, and changes in the eyes and hair are commonly seen.
There is a marked predilection for the left side of the face.
The intraoral tissues also show atrophic changes.
If the teeth are developing they are also similarly affected showing short crown or roots.
There is no treatment but the lesion stops progressing after a certain period of time and remains so for the rest of the life.

Developmental Anomalies : Facial Hemihypertrophy Etiology Clinical Features Oral Manifestations Histologic Features and Treatment
- Vascular abnormalities
- Neurogenic abnormalities
- Hormonal imbalance
- Incomplete twining
- Chromosomal abnormalities
- Intrauterine pressure
- Lymphatic abnormalities
Though the name is Hemihypertrophy, the actual underlying condition is a hyperplasia.
Enlargement of the half of the head and face is seen. Familial occurrence has been seen in many cases.
Other systemic conditions that are found to be associated with facial hemihypertrophy are Wilm’s tumor, adrenocortical tumor and hepatoblastoma.
Enlargement of teeth both primary and permanent are reported.
Early eruption of permanent teeth as well as early shedding of deciduous teeth on the involved side occurs.
The tongue is most commonly involved and shows extremely large papillae.
The buccal mucosa appears velvety and folds of tissues may hang in the oral cavity.
No variation from normal.

Rubber dam was introduced by S.C. Barnum in 1964.
Application of rubber dam is the most successful method of isolating the operating field.
Dry clean operating field
Better access and visibility
Protection of Patient and Operator
Increased operating efficiency
Improves the properties of dental materials indirectly
Objectionable to some patients
Unfavourable Conditions for Dam Placement
Insufficiently erupted teeth
Some third molars
Extremely malpositioned teeth
Some third molars
Rubber dams are available in 5X5 inch and 6X6 inch sheets.
They available in 5 different thickness
|Thin||0.15 mm||(0.006 inch)|
|Medium||0.20 mm||(0.008 inch)|
|Heavy||0.25 mm||(0.0010 inch)|
|Extra Heavy||0.30 mm||(0.012 inch)|
|Special Heavy||0.35 mm||(0.014 inch)|
The rubber dam has a shiny and a dull side.
A rubber dam holder ( frame) is used to secure the borders of rubber dam in stretched condition.
Young´s rubber dam holder is U shaped metal frame with small projections to hold the dam.
Rubber dam retainer or clamp is used to anchor the rubber dam to the most posterior tooth to be isolated.
It consists of four prongs and two jaws connected by a bow.
The prongs make four point contact with the tooth.
The jaws of the retainer should not extend beyond the mesial and distal line angles of the tooth.
Retainers are available with and without wings.
The functions of the wings -
1. To provide extra retraction of the rubber dam from the operating field
2. Allow the attachment of the dam to the retainer before placing it on the tooth.
The disadvantage of the wings is that it interferes with the placement of the matrix bands, band retainers and wedges.
Retainers are not required when isolating anterior teeth except in case of cervical retainer while dealing with class V cavities.
Rubber dam punch is used to make holes in the rubber dam. It has provisions for making holes of 6 different sizes.
Rubber dam luricants are used to lubricate the rubber for easy positioning.
Ideal rubber dam lubricants are water soluble lubricants like soap slurry and shaving cream apart from commercially available specific lubricants.
The corner of the mouth and lips should be protected by cocoa butter or petroleum jelly.
When operating on incisors and mesial surfaces of canines the isolation should extend from first premolar to first premolar.
When operating on canines the isolation field extends from first molar of the same side to the lateral incisor of the opposite side.
For premolars at least two teeth distal to the required tooth and lateral incisors on the opposite side on the opposite side are included.
For molars the isolation extends from the last available tooth to the lateral incisors of the opposite side.
For endodontic purpose only the tooth to be operated on is isolated.
The distance between the holes of rubber dam is 6.3 mm or ¼ inches.
The first hole in the maxillary arch should be punched for central incisor.
For the mandibular arch the first hole should be punched for the most posterior tooth that will receive the retainer.
For class V lesions the holes are punched slightly facial to the arch form. This compensates for the extension of the dam in cervical area.
If the thinner dam dam material is chosen the holes should be smaller because the thinner materials stretch more than the thicker ones.

– Pulp-capping with VivaSens
In individual cases contact with the mucous membranes
may result in short-term reversible irritation. Certain
ingredients of VivaSens may cause sensitization in
predisposed patients or dental personnel which can lead to
allergic contact dermatitis. In such cases, VivaSens should
not be used.
If VivaSens is used to protect dentin before adhesive
restorative treatment, compatibility with the chosen
adhesive must be considered. If used with the Total Etch
adhesive Excite®, VivaSens may be applied after the etching
step and always prior to the adhesive. Interactions with
other Total Etch adhesives (using the same treatment
procedure) are not to be expected but cannot be excluded.
Compatibility with other types of adhesives must be
checked by the user.

Instructions for Use
Skyce is a range of crystal glass tooth jewellery.
The stones are bonded to the labial surfaces of
natural upper anterior teeth without invasive
Colour and sizesColour:
Step by step application
1. A rubber dam must be placed to avoid the
aspiration or swallowing of the tooth jewellery.
2. The contact surface of the tooth must be
professionally cleaned with brushes or cups and
polishing paste, eg Proxyt.
3. A 37-% phosphoric acid gel (eg Total Etch) is
applied to the contact surface. The diameter of
the etched surface must be slightly larger than
that of the stone.
Note: The tooth must be etched for at least 60 s.
4. After 60 s of etching, thoroughly rinse off the
phosphoric acid with water.
5. Carefully dry the tooth surface.
6. Apply a thin coat of Heliobond or Tetric Evo-
Flow onto the etched region.
7. Apply Heliobond or Tetric EvoFlow to the clean
reverse side of Skyce and place the stone on
the tooth surface. Some Heliobond or Tetric
EvoFlow must come out along the sides of the
stone to provide a setting for the stone.
In order to optimize the bond, fully coat the stone
with a thin layer of Heliobond. This does not
impair the lustre of the stone.
Note: Tetric EvoFlow is unsuitable for this pur-
Setting the tooth jewellery with Heliobond
or Tetric EvoFlow.
8. The jewel must be light cured for at least 40 s
both from the labial and palatal aspects (eg
9. If, in rare cases, excess has to be removed, only
use silicone polishers. Rotary instruments must
not touch the stone to prevent scratching.
1. It is easier to apply Skyce if it is held with a
probe to which soft wax or a bit of adhesive
material from the tip of a OptraStick has been
2. Do not touch the stone with your fingers or
allow it to become contaminated with saliva. If
Skyce is contaminated, carefully clean the stone
with acrylic pellets in an alcohol bath.
3. For information about the side effects and
interactions of the cementation materials and
the phosphoric acid gel as well as any
warnings, see the corresponding Instructions
4. Skyce can be removed whenever desired.
