At the end of this topic you should be able to: –Identify the clinical features of the common GIT disorders that have dental or oral significance –Be familiar with the general management of such conditions –Recognize the oral and dental manifestations of this diseases –Know what to treat and what to refer of oral complains related to such diseases
5
Signs and symptoms Dysphagia Dysphagia Dyspepsia or Heartburn: Dyspepsia or Heartburn: –also known as upset stomach or indigestion, refers to a condition of impaired digestion. –It is characterized by chronic or recurrent pain in the upper abdomen –It can be functional dyspepsia ( non-ulcer dyspepsia) or ulcer or erosion related pain as in: – DU, GU, Gastritis and Duodenitis
6
Pain: Pain: –Odynophagia : pain with swallowing –Epigastric pain –Abdominal cramps –It may presented as chest pain !! Bleeding: Bleeding: –Hematemesis: Fresh blood Fresh blood Ground –coffee Ground –coffee –Melena: Fresh Fresh Occult Occult Nausea Nausea
7
Signs and symptoms Vomiting: Vomiting: the forceful expulsion of gastric contents through a relaxed esophageal sphincter and open mouth the forceful expulsion of gastric contents through a relaxed esophageal sphincter and open mouth Diarrhoea: watery or bloody Diarrhoea: watery or bloody –Acute: infections, food poisoning, drugs –Chronic: IBDs, chronic infections
8
Constipation Constipation –perception of abnormal bowel movements that may include straining, hard stools, decreased frequency, and a feeling of incomplete evacuation –It can be caused by: Systemic Systemic Structural Structural Medications Medications Idiopathic Idiopathic
9
Weight loss: Weight loss: –involuntary decrease in body weight of at least 5% is a problem that requires clinical evaluation Regurgitation : Regurgitation : –acid regurgitation –sudden, spontaneous reflux of small volumes of bitter tasting acidic material into the mouth (Mouth brash)

13
Dysphagia
14
–The esophagus is about 25 mm musclar tube (cervical, thoracic, abdominal) –Its basic function is to transport swallowed material from the pharynx into the stomach –Retrograde flow of gastric contents into the esophagus is prevented by the lower esophageal sphincter (LES) –Entry of air into the esophagus is prevented by the upper esophageal sphincter (UES)
15
Dysphagia Swallowing is a complex activity involving a coordinated action of lips, tongue, soft palate, pharynx, larynx and oesophagus which are innervated by VII, IX, X and XII nerves
16
Dysphagia is a subjective difficulty in swallowing Dysphagia is a subjective difficulty in swallowing Unless it is associated with sore throat or oropharyngeal ulceration it is a serious symptom Unless it is associated with sore throat or oropharyngeal ulceration it is a serious symptom It may be: It may be: Total: for solid and liquid and usually indicate a neuralgic cause Selective: for solid as in tumors or benign stricture Intermittent: spasm of crico-laryngeal muscles
17
Etiology Dysphagia could be of: –acute onset as in stroke –slowly developed as in tumour and motor neuron disease
18
The site of the cause may be: 1.In the lumen of oesophagus (foreign body) 2.In the wall of oesophagus (tumour or disorder in motility) 3.Pressure from outside (mass or tumour)
19

Halitosis
35
Halitosis is a term applied oral malodour and to foul, offensive bad breath. is a term applied oral malodour and to foul, offensive bad breath. Others like friends and family members are more aware of halitosis than the individual himself except in case of psychogenic causes Others like friends and family members are more aware of halitosis than the individual himself except in case of psychogenic causes
36
The true prevalence of halitosis is unknown, the available evidence suggests that halitosis is common and can affect people of all ages. The true prevalence of halitosis is unknown, the available evidence suggests that halitosis is common and can affect people of all ages. Most studies have reported that about 20% to 40% of the population have halitosis, although some have reported the figure to be as high as 50%.

54
Peptic ulcers Classified into: –Gastric ulcers –Duodenal
55
–DU are 4 times as common as gastric ulcers and tend to affect young men –Cause is unknown but it is believed to be due to imbalance in acid production and defensive factors such as mucous production, bicarbonate secretion and mucosal resistance –Generally peptic ulcers may be caused by: deregulation of acid production deregulation of acid production Interference with mucosal integrity Interference with mucosal integrity Disruption of mucosal barrier Disruption of mucosal barrier
56
–The integrity of the mucosa is dependent upon the endogenous prostaglandin which promote bicarbonate secretion, maintain mucosal blood flow and are released during epithelial repair –Acid secretion in gastric ulcer is normal or less than normal
57
Predisposing factors of peptic ulcers Infection (Helicobacter pylori): colonization occur in 95% of duodenal ulcers and 70% of gastric ulcer Infection (Helicobacter pylori): colonization occur in 95% of duodenal ulcers and 70% of gastric ulcer –Eradicating H pylori decreases the relapse rate of DU Steroids and NSAID Steroids and NSAID Genetic predisposition (Hereditary): blood group “O” are more susceptible (duodenal) Genetic predisposition (Hereditary): blood group “O” are more susceptible (duodenal) Stress Stress

Inflammatory bowel diseases
91
Inflammatory bowel disease (IBD) Crohn’s disease Crohn’s disease Ulcerative colitis Ulcerative colitis
92
–Inflammatory bowel disease (IBD) involves chronic inflammation of all or part of the digestive tract. –IBD primarily includes ulcerative colitis and Crohn's disease. –Both usually involve severe diarrhea, pain, fatigue and weight loss. IBD can be debilitating and sometimes leads to life-threatening complications.
93
Severe colitis noted during colonoscopy in a patient with inflammatory bowel disease. The mucosa is grossly denuded, with active bleeding noted. The patient had her colon resected very shortly after this view was obtained.
94
Crohn’s disease
96
–Crohn's disease is an IBD that cause inflammation of the lining of the digestive tract. –Chronic granulomatous inflammatory bowl disease that may affect any part of GIT discontinuously (mouth to anus) –In Crohn's disease, inflammation often spreads deep into affected tissues. –Unlike ulcerative colitis it is characterised by skip lesions –Terminal ileum and proximal colon are commonly affected –Young adults are more commonly affected (20-40)
97
Etiology: –Exact cause is unknown but viral, bacterial and food allergy has been incriminated ?? –Genetic predisposition –Interaction between genetic and environmental factors
98
Pathogenesis IBD GenesEnvironment
99
Clinical features: –depend on severity of the disease and site of involvement –may be asymptomatic with signs of malabsorption –abdominal pain that may mimic appendicitis –weight loss –finger clubbing –finger clubbing
100
–abdominal mass (right iliac fossa mass) –per-anal area may show fistula, fissures and sinuses –fever, malaise, uveitis, iritritis and erythema nodosum –The disease progress with relapses and remissions
101
Crohn’s Disease: Anatomic Distribution Small bowel alone (33%) Colon alone (20%) Ileocolic (45%) LeastMost Freq of involvement
102
The great majority of cases (70-85%) of Crohn’s colitis have small bowel involvement and relative sparing of the rectum The great majority of cases (70-85%) of Crohn’s colitis have small bowel involvement and relative sparing of the rectum in IBD major perianal lesions are a feature exclusively of Crohn’s disease. in IBD major perianal lesions are a feature exclusively of Crohn’s disease. In CD There is relatively normal intervening mucosa and segmental rather than diffuse or continuous distribution, and asymmetric involvement of different parts of the wall within given segments of bowel. In CD There is relatively normal intervening mucosa and segmental rather than diffuse or continuous distribution, and asymmetric involvement of different parts of the wall within given segments of bowel. Fistulization into surrounding tissues and organs occurs only in Crohn’s disease as opposed to ulcerative colitis.

Crohn disease is characterized on pathology by non-caseating granulomas but these are not always found on bowel biopsy.
111
Treatment: depend on case severity –Oral steroids: prednisolone –Azathioprine: as steroid sparing agents –Cyclosporine –Sulphasalazine –Surgery: indicated in Symptoms persist despite treatment Symptoms persist despite treatment Intestinal obstruction Intestinal obstruction Local complications: fistulae, abscess, perforation Local complications: fistulae, abscess, perforation
112
Complications of IBD: –Severe life threatening inflammation of colon due to dilatation of the colon and pass of bacterial toxins into portal circulation –Perforation of small intestine or colon –GIT obstruction –Life threatening Bleeding and anemia –Fissures and fistulae of perianal diseases –Ca of bowel –Severe malabsorption
113
Ulcerative colitis Ulcerative colitis is an inflammatory bowel disease that causes long-lasting inflammation and ulcers in the innermost lining of your large intestine (colon) and rectum.
114
Ulcerative colitis –Usually affect large bowel starting at the rectum and proceed proximally (no skip lesions) (no skip lesions) –First attack usually followed by remissions and relapses –Rectal bleeding and bloody diarrhea and mucous discharge –Little constitutional symptoms (fever, lethargy and abdominal discomfort)
115
–Characterized by protracted course that extends over years –Remitting and relapsing course –Both diseases are very similar clinically and it may be very difficult to differentiate between them –The crucial difference is that UC involve only colon while CD can involve any part of GIT
116
Complications of IBD –Longstanding case are at increased risk of developing colon cancer –Severe IBD may cause an acute abdomen termed “toxic megacolon” which may need surgical management

Oral mucosa manifestations of inflammatory bowel disease The changes of the face and oral mucosa associated with inflammatory bowel disease can be divided into four main categories: The changes of the face and oral mucosa associated with inflammatory bowel disease can be divided into four main categories: 1. Specific, meaning these occur only in association with the bowel disease and/or show characteristic histology of that condition. 2. non-specific, meaning these occur more commonly with the bowel disease than in the general population, but also do occur without bowel disease, and the pathology is not diagnostic for the bowel disease. 3. Complications of malabsorption caused by the bowel inflammation resulting in deficiencies in vitamins and minerals. 4. Side effects or complications of medications prescribed to treat the bowel disease.
124
–The first three of these categories may be useful in directing the doctor to the bowel problem and making the specific diagnosis.
125
Oral Signs of Crohn's disease –The oral mucosa is commonly affected in Crohn's disease with up to one third of patients reported to have oral changes, and even higher in children. –In some studies, the oral changes preceded the diagnosis of Crohn's disease in 60%. Of cases –Specific oral mucosal changes: orofacial Crohn's disease (oral Crohn’s) orofacial Crohn's disease (oral Crohn’s)

140
Pyostomatitis vegetans Pyostomatitis vegetans (PV) is a rare condition characterized by pustules that affect the oral mucosa. It is a highly specific marker for inflammatory bowel disease (UC in particular) and its correct recognition may lead to the diagnosis of ulcerative colitis or Crohn’s disease. Thus, a presumptive diagnosis of PV should suggest a complete gastrointestinal investigation
141
