Smile is more than a form of communication; it is kind of socialization
and attraction. Although moderate gummy smile can be quite acceptable and
esthetically pleasing if the gum is healthy, more pronounced cases are
less well tolerated and require treatment.

Smile analysis in vertical dimention:- factors to be considered when observed...Dr.Maulik patel
This is article description of smile when observing in vertical dimension ,maily used by dentist (orthodontist) while treatment of gummy smile with braces.
Smile: is the most pleasant and wanted expression by each one of us.
Smile: is amused facial expression with the corner of mouth turned up and exposed front teeth
Facial expression, postures of lips, occlusion and arrangement of teeth, buccal corridor, shape of teeth, gingival color, texture, contour and other several aspects constitute component of smile
Most of patients come to us to improve their smiles, the orthodontic studies stress on skeletal structure than soft tissue structure, and the smile still receives relatively little attention
Nature of smile:
1- Posed smile: voluntary, static, sustained, social smile not elicited by an emotion
2- Un-posed smile: spontaneous, involuntary, dynamic, natural, and not sustained characterized by greater lip elevation
Smile types: smile styles:
1- Commissures smile: the corner of the mouth turned upward called Monalisa smile
2- Cuspid smile: the upper lip is elevated, the entire lip rises like a window shade
3- Complex smile: the upper lip moves superiorly as in cuspid smile and lower lip moves inferiorly
Evaluation of posed smile:
variables Normal smile Not good smile
Smile arc Consonant Non consonant
Smile index Average Increased / decreased
Morley’s ratio 75 – 100% (normal) Disturbed
Buccal corridor Average Obliterated / excessive
Smile line Average High / low
Occlusal plane No canting Canting occlusal plane
Important definitions:
Smile arc:
the curvature formed by an imaginary line tangent to the incisal edges of the teeth, modified in varying degree of curvature in relationship to the lower lip
Range: from no curvature to an accentuated curvature was in relation to the lower lip, so quantification differed for each model
Buccal corridor:
the amount of dark space displayed between the facial surfaces of the posterior teeth and the corner of the mouth, calculated as the total dark space on both sides of the mouth as a percentage of the total smile width
Range: from 6% to 26.5 in approximately 0.5% increments
Maxillary gingival display or gummy smile:
The amount of gingival show above the central incisor crown and below the center of the upper lip. Negative number indicate gingival exposure. Positive number indicate tooth overlap by the lip
Range: from 1mm of gingival display (-1) to almost 7mm of tooth coverage for the female models, and approximately 2mm of gingival display (-2) to 6mm tooth coverage for male models
The variation between the models was due to differences in sizes and coordinating the images for different faces
Maxillary midline to face:
The relationship of maxillary dental midline (measured between the central incisors) to the midline of the face, defined by the center of the philtrum and the facial midline
Range: the maxillary midline was moved to the left of the face in approximately 0.25 mm increments. The right and left buccal corridor was maintained throughout the movement of the dentition. The maximum deviation show is 6mm

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

18. 2 Factors Influencing the Gingival Display :
1 - Age
Gingival Smile Line Diminishes With Age
2 - Sex
Low Smile Line is a Male Characteristic , While
High Smile Line Is a Female Characteristic
19. In most children ,lip incompetency , is considered as a” transient
condition” that will be self-corrected after puberty due to the
maturation of the oro-facial musculature .
20. The effects of maturation and aging on the soft
tissues of the face can be summarized as:
(1) lengthening of the resting philtrum and commissure heights,
(2) decrease in turgor (or tissue “fleshiness”),
(3) decrease in incisor display at rest,
(4) decrease in incisor display during smile, and
(5) decrease in gingival display during smile .

31. Short Upper Lip :
- Short philtrum relative to the commissures
The average length of the upper lip is :
• 22-24 mm in males
• 20-22 mm in females
32. • Short upper lip type
• Between 6 and 40 years :
• Philtrum lengthening > Commissures lengthening
33. Hypermobile Upper Lip :
- Extreme elevation of the upper lip on smile due
to hyperfunction of the elevator muscles
Apical movement of the upper lip,
from rest to maximum smile, is more
than 9-10 mm .
The average elevation of the
upper lip on smile is : 7-8 mm
34. Hyperomobility of the Upper Lip
Normal Vertical Proportions
Normal Clinical Crown Lengths
Excessive Contraction of the Elevators of the upper lip
35. Altered ( Delayed ) Passive Eruption
• Delayed
migration of the gingival
margin in an apical direction
36. Tooth Eruption
Active Eruption
Movement of the teeth in
the occlusal direction
Passive Eruption
Exposure of the teeth by
apical migration of the

37. Delayed Passive Eruption
• During adolescence, the gingival
margin migrates apically until it
reaches its adult position of 1mm
coronal to the cemento-enamel
junction( CEJ) .

38. Altered Passive Eruption
• Failure of the gingival tissue to adequately recede to the
proper level relative to the cemento-enamel junction( CEJ) .
al
Prevalence : 12.1% ( 7% in men , 14% in women )
39. Active Altered Passive Eruption
The Active Eruption of the teeth is complete by age 12 for the
maxillary central incisors and canines. The maxillary lateral
incisors continue to demonstrate minor changes in gingival margin
position up to 16 years of age.

A Condition in which the
Gingival Margin is positioned
coronally on the anatomic
crown in adulthood and does
not approximate the CEJ .
41. Clinical Crown Length
Vertical height of the maxillary
central incisor in adult is normally
between 9-12 mm , with an average
of :
10.6 mm in males , and
9.5 mm in females
42. Clinical Crown Length
Ideal maxillary central incisor proportion is
approximately 80% width compared with height, with
ranges between 66% and 80%
43. Diagnosis of Altered Passive Eruption
• Clinical crowns << the anatomic crowns
Evaluation of the position of the cementoenamel
junction( CEJ) of the maxillary incisors relative to both
the gingival margins and incisal edges of these teeth.
44. Short clinical crown height associated with a Gummy
Smile condition could be due to :
- Lack of eruption
- Gingival enlargement
- Severe attrition
45. Detorqued or Lingually tipped maxillary incisors :
- Lower crown position and subsequent increase in
tooth and gingival display .

46. Summary : Etiological Classification of
Gummy Smile Conditions
Skeletal Type
Dento –Alveolar Type
Muscular Type
Short Upper Lip Type
Dento-gingival Type
47. Differential Diagnosis
• When planning treatment for a gummy smile the
key is to diagnose the reason for excessive
gingival margin-to -lip distance when the patient
smiles .
48. Gummy Smile
- Differential Diagnosis
1st Step
Assessment of the upper lip relative to the incisal
edges of the maxillary incisors At Rest :
- Normal incisor display = 3- 4 mm
49. Gummy Smile
- Differential Diagnosis
Normal ( 3- 4 mm) incisor display At Rest , But there
is a Gummy Smile ???
- The G.S Is due to either :
- Hyperomobility of the Upper Lip or
- Altered Passive Eruption
50. Gummy Smile
- Differential Diagnosis
Hyperomobility of the Upper Lip
•M.Polo . AJO-DO,2008
The incidence of gummy smile
secondary to hyperfunctional upper lip
elevator musculature is about 0.1%.
A marked tendency for greater incidence
of excessive gingival display appears to
be present in females .
51. Gummy Smile
- Differential Diagnosis
Assessment of the upper lip relative to the incisal
edges of the maxillary incisors At Rest :
- If incisor display > 3- 4 mm then the
Possible Causes :
• Short Upper Lip
• Overeruption of Maxillary Incisors
• Vertical Maxillary Excess
52. Gummy Smile
- Differential Diagnosis
• Short Upper Lip ,vs,
• Overeruption of Maxillary Incisors
• Vertical Maxillary Excess
Evaluation of the Lower Anterior Face Height
Cephalometrically :
- If Normal : the problem is related to short

Face Height Cephalometrically :
- If Increased : the problem is due to
Vertical Maxillary Excess
56. Gummy Smile
- Differential Diagnosis
• Overeruption of Maxillary Incisors ,vs,
• Vertical Maxillary Excess
- Coronal Positioning of Maxillary Incisors ( Relative to
Post. Occlusal Plane ) IF they were Over-erupted .
57. Gummy Smile
- Differential Diagnosis
In the case of Vertical Maxillary Excess :
Both anterior and posterior teeth are overerupted
relative to the patient’s facial soft tissues
59. Treatment Methods
Treatment of the Gummy Smile Varies
According to the Etiological Factors ,
Perception and Expectations of the
Patient .
60. Treatment Options
Control or modification of certain aspects of facial
growth ( growing patients )
Maxillary incisor intrusion by Orthodontic means .
Surgical maxillary impaction
Gingivectomy and Apically Repositioned Flap
Restriction of the upper lip elevation when smiling
( surgical , Botox injection … )
• The Definitive Diagnosis of the Problem Determines
the Appropriate Treatment .

103. • Treatment of Gummy Smile Due to:
Vertical Maxillary Excess
• Superior Repositioning of the Maxilla through
Le Fort I Osteotomy .
Indications:
- Long lower face height
- Lip incompetence
- Excessive exposure of maxillary anterior teeth
• Limitation : the upper lip may be considerably shortened
111. Biological width
Distance of gingival margin to bone on labial is 3mm. 2 mm of
this is crevice depth, and 1mm. is for connective tissue between
probable depth and crest of bone.
112. Treatment of Altered Passive Eruption : Gingivectomy
5 millimeters of crevice depth with adequate band of
Keratinized tissue .
Gingivectomy can be used to increase crown length by
up to 3 mm
113. Gingivectomy
This patient requires 3 mm of
crown lengthening
Sufficient crevice depth and
Keratinized tissue
114. Treatment of Altered Passive Eruption : Gingivectomy
Crowns placed twelve weeks after Gingivectomy
115. Treatment of Altered Passive Eruption :
- Apically Repositioned Flap
Short clinical crowns with
large gingival display on
smiling
Insufficient gingival crevice
depth for Gingivectomy
116. Treatment of Altered Passive Eruption :
- Apically Repositioned Flap
• Flap elevated and bone recontoured
119. Gingival hyperplasia
Surgical removal after debanding if needed to enhance
posttreatment stability
If interfere tooth movement - surgical removal
121. Treatment of Hypermobile Upper Lip :
- Surgical Lip Repositioning
- Botox Injection
Objective :
- To Decrease the amount of lip elevation on smiling .
- Lowering the height of the gingivolabial sulcus .

Lip Repositioning Technique
•The procedure restricts the muscle pull of the elevator lip
muscles by shortening the vestibule , thus reducing the gingival
display when smiling .

131. • When injected intramuscularly at therapeutic doses, BTX-A produces
partial chemical denervation of the muscle, resulting in localized reduction
in muscle activity.

Mario Polo , Am J Orthod Dentofacial Orthop 203-133:195;2008
BTX-A injections for the neuromuscular correction of gummy smile
caused by hyperfunctional upper lip elevator muscles was effective and
statistically superior to baseline smiles , although the effect was transitory .
