HEALING
General Pathology
HEALING
Definition. Replacement of damages tissue by healthy tissue. It is an attempt to restore the tissue to structural and functional normalcy.
Healing may be of 2 types
A. Regeneration.
B. Repair by granulation tissue.
A. Regeneration
Where the replacement is by proliferation of parenchymatous cells of type destroyed. This depends upon:
(1) Regenerative capacity of cells. Cells may be :
(a) Labile cells which are constantly proliferating to replace cells continuously shed off or destroyed
Epithelial cells of skin and lining surfaces.
Lymphoid and haemopoietic tissue.
(b) Stable cell. Cells mostly in resting-phase, but capable of dividing when necessary e.g.
Liver and other parenchymatous and glandular cells.
Connective tissue cells.
Muscle cells have a limited capacity to divide.
(c) Permanent cell. These cells, once differentiated are not capable. of dividing e.g.-nerve
(2) The extent of tissue loss. If there is extensive destruction including disruption of the framework, complete.regeneration is not possible. even with labile an stable cell
B. Repair by granulation tissue
Granulation tissue is formed by proliferation of surrounding connective tissue elements. which migrate into the site to be repaired.
Granulation tissue formation seen in :
Wound healing.
Organisation of exudates.
Thrombi.
Infarcts.
Haematomas.
The process of repair can be best studied in clean incised wounds, where there is .no or minimal tjssue loss or the_edges or the edges of the wound are approximated closely as in a surgical wound. This is called Primary union (healing by first intention).
1. The blood in the incised area clots and the fibrin binds the edges together.
2. During the first 24 hours, an acute inflammation sets in to .bring protein and phagocyte rich exudates to the site.
3. The superficial part of the clot get dry and dehydrated{scab). The surface epithelium proliferates just beyond the cut edges and the cells migrate-deep to dry scab. Epithelialisation is usually complete by 24- 48 hours.
4 Granulation tissue, with actively growing fibroblasts and capillary buds invades the clot (stage of vascularisation). These fibroblasts 'posses contractile myofibrils & hence are termed as myofibroblasts'.
5. Simultaneously, demolition of the debris and clot components takes place.
6 The granulation tissue initially lays down a mucopolysacharide rich ground substance
7.Reticulin and later collagen fibrils are formed by the fibroblasts (with 5 days)
8 with progressive maturation of collagen, some of the capiliary buds develop into arterioles and venules and majority of them are obliterated (stage of devascularisation).
9. With time (weeks to months) the tensile strength of the scar increases and it shrinks.
Secondary union (excised wound-healing by secondary intention).
1. Coagulum forms and fills the gap.
2. Inflammatory reaction is seen as in primary union but is more intense, as a lot more debris has to be removed. .
3. Epithelial proliferation starts covering the surface from the periphery by proliferation beyond the edges and migration under scab.
4.Debridement starts and simultaneously granulation tissue grows into the coagulum from the sides and base of the wound. This is much more exuberant than in primary union. The surface now looks red and granular.
5. Wound contraction. This is early contraction (starts after 3 days and is complete in 2 weeks) and must be differentiated from contraction after scar formation Wounds can contract by up to 80% of original size of that the gap to be filled is much reduced, resulting in faster healing with a smaller scar.
Wound contraction is probably caused by:
Dehydration
Collagen contraction.
Granulation tissue contraction .(myofibroblasts).
The exact mechanism is not known.
6. Laying down of collagen.
7 Maturation to form a scar which later shrinks and devascularises.
Factors affecting wound healing
Wound healing is delayed by :
A. Local factors
1. Poor blood supply.
2. Adhesion to bony surfaces (e.g. over the tibia).
3. Persistent injurious agents (infective or particulate) results in chronicity of inflammation and ineffective healing. .
4. Constant movement (especially in fracture healing).
5. ionizing radiation (in contrast, ultraviolet rays hasten healing).
6. Neoplasia.
B. General factors
I. Nutritional deficiency, especially of.
(i) Protein
(ii) Ascorbic acid (Vitamin C).
(iii) Zinc
2. Corticoids adversely affect wound contraction and granulation tissue formation
(anabolic steroids have a favorable effect).
3. Low temperature.
4. Defects (qualitative or quantitative) in polymorphs and macrophages
.Complication of wound healing
1. Wound dehiscence
2. Infection
3. Epidermal inclusion (implantation) cysts.
4. Keloid formation
5. Cicatrisation resulting in contract Ires and obstruction(in hollow viscera).
6. Calcification and ossification.
7. Weak scar which could be a site for incisional hernia
8. Painful scar if it involves a nerve twig.
9. Rarely neoplasia (especially in burn scars).
The Lips
AnatomyThe Lips
These are mobile muscular folds that surround the mouth, the entrance of the oral cavity.
The lips (L. labia) are covered externally by skin and internally by mucous membrane.
In between these are layers of muscles, especially the orbicularis oris muscle.
The upper and lower lips are attached to the gingivae in the median plane by raised folds of mucous membrane, called the labial frenula.
Sensory Nerves of the Lips
The sensory nerves of the upper and lower lips are from the infraorbital and mental nerves, which are branches of the maxillary (CN V2) and mandibular (CN V3) nerves.
INFECTION
General Surgery
1 Cellulitis: a non-suppurative inflammation of subcutaneous tissue, extending along connective tissue planes and across intercellular spaces.
Spreading inflammation in the tissue planes is called cellulitis. There is wide spread swelling, redness and pain without definite localization.
Caused by Streptococcus pyogenes.. If general condition of the patient is undermined, as in diabetes, cellulitis spreads rapidly and leads to Septicemia (infection in the blood).Redness, itching and stiffness is present in the site of inoculation (where the bacteria enter the skin), local Gangrene (death of the tissue) may occur. The appearance of skin creases or wrinkles, indicates resolution (healing).
Treatment
1. Rest , Appropriate antibiotics.
Cellulitis of the neck: Is a complication of wounds tonsillitis or mastoiditis Ludwig’s angina is the term applied to sub-maxillary cellulitis. The two dangers of cervical cellulitis are:
1. Oedema of glottis - with possible asphyxia (respiratory obstructon )
2. Mediastinitis - In ludwig’s angina the floor of the mouth become oedematous. The tongue can be seen displaced, turned upwards by swelling and oedema. The patient is unable to close the mouth owing to oedema of the tongue and the floor of the mouth. This can also CCC when the tongue is bitten by a wasp.
Ludwig’s angina: Ludwig - characterized by a brawny (non pitting) swelling of the sub-mandibular region, corn with inflammatory oedema of the mouth. It is the combined cervical and intrabuccal signs that constitute the characteristic feature of the lesion. The cause of the condition is virulent, usually streptococcal infection of the cellular tissue surrounding the sub-mandibular salivary gland.
Clinical features
The swollen tongue is pushed towards the palate and forwards through the open mouth, while the cellulitis extends down the neck.
The most dangerous plane, is deep to the deep fascia.
Ludwig’s angina is an infection of closed fascial space and if .untreated, the inflammatory exudate often passes via, the tunnel occupied by stylohyhoid to the submucosa of glottis, in which event the patient is in immediate danger of death from oedema of the glottis.
Treatment
1. antibiotics on Early Diagnosis
2. In cases where the swelling, both cervical and intrabuccal, does not subside rapidly with such treatment, a curved incision, beneath the jaw is made and this decompresses the closed fascial space. The incision is deepened and after displacing the superficial lobe of the sub-mandibular salivary gland, the mylohyoid muscle are divided. This decompresses the closed fascjal space referred to. The wound is lightly sutured and drained. The operation can be conducted with greatest safety under local anaesthesia.
Bacteraemia and Septicemia
Bacteraemia and septicaemia means the organisms are present in the blood. Clinical features are those of severe infection and shock: , Pyrexia is intermittent , Rigors , Jaundice is due to liver damage, Acute renal failure may occur , Peripheral circulatory failure, lntravascular coagulation indicates a fatal outcome
causative focus found and treated surgically .g., Appendicetomy in perforated appendix
2. Blood culture taken
3. Broad spectrum antibiotic is given
4. Blood transfusion is given.
5. Injection hydrocortisone is given.
Pyaemia
Pyaemia is due to infected emboli circulating in blood stream. Pyaemia is characterized by: -
1. Rigors
2. Intermittent fever
3. Formation of abscess in vital organs like heart or brain.
Treatment
1. Is to prevent emboli reaching the blood stream
2. Broad spectrum antibiotic is given.
3. Abscess are incised and drained
If not treated portal pyaemia with multiple abscesses in liver occur, which is a dangerous condition.
Acute Abscess : An abscess a collection of pus.
Bacteria which cause pus formation is called pyogenic organisms. Bacteria reach the infected area by:
1. Direct route: eg. Penetrating wound
Local extension: From adjacent focus of infection
2 Lymphatics
4. Blood stream
Pyogenic membrane surrounds the abscess and is infiltration with (leukocytes and bacteria.
Pus: Pus contains dead leukocytes and bacteria. It reaches the surface of the body or is discharged into a hollow viscous.
Symptoms: patient feels ill., Throbbing pain is characteristic of suppuration. Pain becomes more severe in the dependent position. E.g. infected finger,
Classical signs
Temperature is elevated , Rigors, inflammation
Fluctuation: Present in the later stages, and reveals the presence of pus. Prevention
1. An abscess can sometimes be aborted by antibiotics in the early stage.,. Rest, Elevation of the affected part.
Treatment
Is incision and drainage of abscess
Hilton’s method of opening an abscess:
It is used where important anatomical structures like the blood vessels and nerves are preesnt, as in the neck, axilla and groin. The skin and superficial fascia is incised. A sinus forceps is thrust into the abscess cavity. The blades are opened and the pus is drained. A gloved finger is introduced and loculi are broken. A ribbon gauze is lightly packed and antibiotics are given. This is done under surface anaesthesia i.e., ethyl chloride spray.
Antibioma
If antibiotic is given the pus in the abscess frequently becomes sterile and a large brawny edematous swelling remains which takes many weeks to resolve.
Treatment: explore the mass with a wide-bore aspirating needle
Most antibiornas are due to late, inadequate, and ineffective antibiotics.
CANCRUM ORIS
Is an infective gangrene of cheek and lip.
may occur as a complication of kala azar, enteric fever and children with poor oral hygiene.
The lesion starts as an acute inflammatory patch on oral mucosa which is seen ulcerated.
The affected part of the cheek or the lip gradually becomes gangrenous.
Focal vascular thrombosis and sepesis occur.
When slough separates, a part of the cheek or lip sloughs out to form a buccal fistula with ugly deformity. The adjacent jaw may be infected too.
Various organisms are found - specially Fusiform bacillus and_Borrellia vincenti.
The foetid odour, gangrenous patch of cheek or lip, purulent discharge from the mouth, fever and toxaemia are the characteristic features. The patient is unable to open the mouth properly.
Treatment
1. Antibiotics, multivitamins and repeated mouth washes
2 Neostibamine in kala-azar. Sequestrectomy in chronic osteomyelitis of the mandible.
4. Plastic reconstruction of the lip or cheek for unsightly deformity undertaken.
CARBUNCLE
Is an infective gangrene of the subcutaneous tissue. It is due to staphylococcal aureus infection. It is uncommon before the age of 40. Males are the usual sufferers. Diabetes may be present. It often occurs on the nape of the neck.
Clinical features
Subcutaneous tissue becomes painful and indurated. Ove skin is red. Unless treated promptly, extension will occur and late softening. The skin gives way and thick pus and slough are discharged.
Usually, there is one central large slough, surrounded by smaller areas of necrosis. Infection extends widely and fresh openings appear
Treatment
1. Many carbuncles are aborted, if penicillin is used adequately in the early stage.
2. Local treatment consists of hygroscopic dressings being given ie. magsulph-glycerin dressing Later the carbuncle is excised with a cruciate incision.
3. If the gap is large and when the granulation tissue comes to the surface, skin grafting is done.
MAXILLARY SECOND BICUSPID
Dental Anatomy
MAXILLARY SECOND BICUSPID
smaller in dimensions. The cusps are not as sharp as the maxillary first bicuspid and have only one root.
Facial: This tooth closely resembles the maxillary first premolar but is a less defined copy of its companion to the mesial. The buccal cusp is shorter, less pointed, and more rounded than the first.
Lingual: Again, this tooth resembles the first. The lingual cusp, however, is more nearly as large as the buccal cusp.
Proximal: Mesial and distal surfaces are rounded. The mesial developmental depression and mesial marginal ridge are not present on the second premolar.
Occlusal: The crown outline is rounded, ovoid, and is less clearly defined than is the first.
Contact Points; When viewed from the facial, the distal contact area is located more cervically than is the mesial contact area.
Sampling methods in Public Health Dentistry
Public Health DentistrySampling methods are crucial in public health dentistry as they enable
researchers and practitioners to draw conclusions about the oral health of a
population based on a smaller, more manageable subset of individuals. This
approach is cost-effective, time-saving, and statistically valid. Here are the
most commonly used sampling methods in public health dentistry with their
applications:
1. Simple Random Sampling: This is the most basic form of
probability sampling, where each individual in the population has an equal
chance of being selected. It involves the random selection of subjects from a
complete list of all individuals (sampling frame). This method is applied when
the population is homogeneous and the sample is expected to be representative of
the entire population.
It is useful in studies that aim to determine prevalence of dental caries or
periodontal disease in a community, assess the effectiveness of oral health
programs, or evaluate the need for dental services.
2. Stratified Random Sampling: This technique involves dividing
the population into strata (subgroups) based on relevant characteristics such as
age, gender, socioeconomic status, or geographic location. Random samples are
then drawn from each stratum. This method ensures that the sample is more
representative of the population by reducing sampling error.
It is often used when the population is heterogeneous, and there is a
need to analyze the data separately for each subgroup to understand the impact
of different variables on oral health.
Applications:
Oral Health Disparities: Stratified sampling can be
used to ensure representation from different socioeconomic groups when
studying access to dental care.
Age-Specific Studies: In research focusing on pediatric
dental health, stratified sampling can help ensure that children from
various age groups are adequately represented.
3. Cluster Sampling: In this method, the population is divided
into clusters (e.g., schools, neighborhoods, or dental clinics) and a random
sample of clusters is selected. All individuals within the chosen clusters are
included in the study. This approach is useful when the population is widely
dispersed, and it reduces travel and data collection costs. It is often applied
in community-based dental health surveys and epidemiological studies.
Applications:
School-Based Dental Programs: Cluster sampling can be
used to select schools within a district to assess the oral health status of
children, where entire schools are chosen rather than individual students.
Community Health Initiatives: In evaluating the
effectiveness of community dental health programs, clusters (e.g.,
neighborhoods) can be selected to represent the population.
4. Systematic Sampling: This technique involves selecting every
nth individual from the sampling frame, where n is the sampling interval. It is
a probability sampling method that can be used when the population has some
order or pattern. For instance, in a school-based dental health survey, students
from every third grade might be chosen to participate.
This method is efficient for large populations and can be representative if
the sampling interval is appropriate.
Applications:
Community Health Assessments: Systematic sampling can
be used to select households for surveys on oral hygiene practices, where
every 10th household is chosen from a list of all households in a
neighborhood.
Patient Records Review: In retrospective studies,
systematic sampling can be applied to select patient records at regular
intervals to assess treatment outcomes.
5. Multi-stage Sampling: This is a combination of different
sampling methods where the population is divided into smaller and smaller
clusters in each stage. It is particularly useful for large-scale studies where
the population is not easily accessible or when the study requires detailed data
from various levels (e.g., national to local levels).
For example, in a multi-stage design, a random sample of states might
be selected in the first stage, followed by random samples of counties within
those states, and then schools within the selected counties.
Applications in Public Dental Health:
National Oral Health Surveys: Researchers may first
randomly select states or regions (clusters) and then randomly select dental
clinics or households within those regions to assess the prevalence of
dental diseases or access to dental care.
Community Health Assessments: In a large city,
researchers might select neighborhoods as the first stage and then sample
residents within those neighborhoods to evaluate oral health behaviors and
access to dental services.
Program Evaluation: Multi-stage sampling can be used to
evaluate the effectiveness of community dental health programs by selecting
specific program sites and then sampling participants from those sites.
6. Convenience Sampling: Although not a probability sampling method,
convenience sampling is often used in public health dentistry due to practical
constraints. It involves selecting individuals who are readily available and
willing to participate. While this method may introduce bias, it is useful for
pilot studies, exploratory research, or when the goal is to obtain preliminary
data quickly and inexpensively. It is important to be cautious when generalizing
findings from convenience samples to the broader population.
Applications:
Pilot Studies: Convenience sampling can be used in
preliminary studies to gather initial data on dental health behaviors among
easily accessible groups, such as dental clinic patients.
Focus Groups: In qualitative research, convenience
sampling may be used to gather opinions from dental patients who are readily
available for discussion.
7. Quota Sampling: This is a non-probability sampling method
where the researcher sets quotas for specific characteristics of the population
(e.g., age, gender) and then recruits individuals to meet those quotas. It is
often used in surveys where it is crucial to have a representative sample
regarding certain demographic variables.
However, it may not be as statistically robust as probability sampling
methods and can introduce bias if the quotas are not met correctly.
Applications in Public Dental Health:
Targeted Surveys: Researchers can use quota sampling to
ensure that specific demographic groups (e.g., children, elderly, low-income
individuals) are adequately represented in surveys assessing oral health
knowledge and behaviors.
Program Evaluation: In evaluating community dental
health programs, quota sampling can help ensure that participants reflect
the diversity of the target population, allowing for a more comprehensive
understanding of program impact.
Focus Groups: Quota sampling can be used to assemble
focus groups for qualitative research, ensuring that participants represent
various perspectives based on predetermined characteristics relevant to the
study.
8. Purposive (Judgmental) ampling: In this approach,
participants are selected based on specific criteria that the researcher
believes are important for the study. This method is useful for studies that
require in-depth understanding, such as qualitative research or when studying a
rare condition. It is essential to ensure that the sample is diverse enough to
provide a comprehensive perspective.
Applications:
Expert Interviews: In studies exploring dental policy
or public health initiatives, purposive sampling can be used to select key
informants, such as dental professionals or public health officials.
Targeted Health Interventions: When studying specific
populations (e.g., individuals with disabilities), purposive sampling
ensures that the sample includes individuals who meet the criteria.
9. Snowball Sampling: This is a non-probability method where
initial participants are selected based on the researcher's judgment and then
asked to refer others with similar characteristics. It is often used in studies
involving hard-to-reach populations, such as those with rare oral conditions or
specific behaviors.
While it can provide valuable insights, the sample may not be representative
of the broader population.
Applications :
Studying Marginalized Groups: Researchers can use
snowball sampling to identify and recruit individuals from marginalized
communities (e.g., homeless individuals, low-income families) to assess
their oral health needs and barriers to accessing dental care.
Behavioral Research: In studies examining specific
behaviors (e.g., smoking and oral health), initial participants can help
identify others who share similar characteristics or experiences,
facilitating data collection from a relevant population.
Qualitative Research: Snowball sampling can be
effective in qualitative studies exploring the experiences of individuals
with specific dental conditions or those participating in community dental
health programs.
10. Time-Space Sampling: This technique is used to study
populations that are not fixed in place, such as patients attending a dental
clinic during specific hours. Researchers select random times and days and then
include all patients who visit the clinic during those times in the sample.
This method can be useful for assessing the representativeness of
clinic-based studies.
Applications
Mobile Populations: Researchers can use time-space
sampling to assess the oral health of populations that may not have a fixed
residence, such as migrant workers or individuals living in temporary
housing.
Event-Based Sampling: Public health campaigns or dental
health fairs can be used as time-space sampling points to recruit
participants for surveys on oral health behaviors and access to care.
Community Outreach: Time-space sampling can help
identify individuals attending community events or clinics to gather data on
their oral health status and service utilization.
The choice of sampling method in public health dentistry depends on the research
question, the population's characteristics, the available resources, and the
desired level of generalizability. Probability sampling methods are generally
preferred for their scientific rigor, but non-probability methods may be
necessary under certain circumstances. It is essential to justify the chosen
method and consider its limitations when interpreting the results.
Thrombolytic Agents
Pharmacology
Thrombolytic Agents:
Tissue Plasminogen Activator (t-PA, Activase)
t-PA is a serine protease. It is a poor plasminogen activator in the absence of fibrin. t-PA binds to fibrin and activates bound plasminogen several hundred-fold more rapidly than it activates plasminogen in the circulation.
Streptokinase (Streptase)
Streptokinase is a protein produced by β-hemolytic streptococci. It has no intrinsic enzymatic activity, but forms a stable noncovalent 1:1 complex with plasminogen. This produces a conformational change that exposes the active site on plasminogen that cleaves a peptide bond on free plasminogen molecules to form free plasmin.
Urokinase (Abbokinase)
Urokinase is isolated from cultured human cells.Like streptokinase, it lacks fibrin specificity and therefore readily induces a systemic lytic state. Like t-PA, Urokinase is very expensive.
Contraindications to Thrombolytic Therapy:
• Surgery within 10 days, including organ biopsy, puncture of noncompressible vessels, serious trauma, cardiopulmonary resuscitation.
• Serious gastrointestinal bleeding within 3 months.
• History of hypertension (diastolic pressure >110 mm Hg).
• Active bleeding or hemorrhagic disorder.
• Previous cerebrovascular accident or active intracranial bleeding.
Aminocaproic acid:
Aminocaproic acid prevents the binding or plasminogen and plasmin to fibrin. It is a potent inhibitor for fibrinolysis and can reverse states that are associated with excessive fibrinolysis.
Dimensions of Toothbrushes
PeriodontologyDimensions of Toothbrushes
Toothbrushes play a crucial role in maintaining oral hygiene, and their
design can significantly impact their effectiveness. The American Dental
Association (ADA) has established guidelines for the dimensions and
characteristics of acceptable toothbrushes. This lecture will outline these
specifications and discuss their implications for dental health.
Acceptable Dimensions of Toothbrushes
Brushing Surface Dimensions:
Length:
Acceptable brushing surfaces should measure between 1 to
1.25 inches (25.4 to 31.8 mm) long.
Width:
The width of the brushing surface should range from 5/16
to 3/8 inch (7.9 to 9.5 mm).
Rows of Bristles:
Toothbrushes should have 2 to 4 rows of bristles to
effectively clean the teeth and gums.
Tufts per Row:
Each row should contain 5 to 12 tufts of
bristles, allowing for adequate coverage and cleaning ability.
Filament Diameter:
The diameter of the bristles can vary, affecting the stiffness and
cleaning effectiveness:
Soft Filaments:
Diameter of 0.2 mm (0.007 inches). Ideal
for sensitive gums and children.
Medium Filaments:
Diameter of 0.3 mm (0.012 inches). Suitable
for most adults.
Hard Filaments:
Diameter of 0.4 mm (0.014 inches).
Generally not recommended for daily use as they can be abrasive
to the gums and enamel.
Filament Stiffness:
The stiffness of the bristles is determined by the diameter relative
to the length of the filament. Thicker filaments tend to be stiffer,
which can affect the brushing technique and comfort.
Special Considerations for Children's Toothbrushes
Size:
Children's toothbrushes are designed to be smaller to accommodate
their smaller mouths and teeth.
Bristle Thickness:
The bristles are thinner, measuring 0.005 inches (0.1
mm) in diameter, making them gentler on sensitive gums.
Bristle Length:
The bristles are shorter, typically around 0.344 inches (8.7
mm), to ensure effective cleaning without causing discomfort.
Clinical Implications
Choosing the Right Toothbrush:
Dental professionals should guide patients in selecting toothbrushes
that meet ADA specifications to ensure effective plaque removal and gum
protection.
Emphasizing the importance of using soft or medium bristles can help
prevent gum recession and enamel wear.
Education on Brushing Technique:
Proper brushing technique is as important as the toothbrush itself.
Patients should be educated on how to use their toothbrush effectively,
regardless of the type they choose.
Regular Replacement:
Patients should be advised to replace their toothbrush every 3
to 4 months or sooner if the bristles become frayed. This
ensures optimal cleaning effectiveness.
Special Considerations for Children:
Parents should be encouraged to choose appropriately sized
toothbrushes for their children and to supervise brushing to ensure
proper technique and effectiveness.
