Editorial :

      Dear Fellow Dentist,

The higher the technology goes , the higher is the feeling of going back to basics. Ultimately inspite of the high technology it  is the basic skills of the dentist that plays a mojor role in the treatment outcome. Sometimes the treatment for a particular ailment could perhaps be in some bug. In one of the articles this issue , there is about " Amblyomma cajennense" a blood sucking parasite which holds the future of cancer care.

I welcome more and more of you to send your cases or articles for Dental Follicle .

Halitosis -Breath Malodor - A review

By Dr.Ghazala Danish MDS

Oral Diagnostitian & Radiologist

 

Introduction

Breath malodor means an unpleasant odor of the expired air, whatever the origin may be. Oral malodor specifically refers to such odor originating from the oral cavity itself. A term like halitosis is synonymous with breath malodor. There are references to it in the Bible and in the Koran. Surprisingly enough, until recently breath malodor has not been a matter of much interest in periodontology, although its most frequent causes are plaque-related gingivitis and periodontitis.

Breath malodor should not be confused with the momentarily disturbing odor caused by food intake (e.g., garlic) or smoking because these odors do not reveal a health problem. The same is true for morning bad breath: as habitually experienced on awakening.

A persistent breath malodor, by definition, does reflect some pathology.

Imaginary breath odor or halitophobia, well-established personality disorder questionnaires allow the clinician to assess the patient's tendency for illusional breath malodor.

 

Morning bad breath

Transient breath malodor is noticed when waking up in the morning in more man half the adult population. It does not deserve special attention since it is due to the xerostomia developed during sleep, i.e. when salivary flow is reduced to a minimum. This with the ongoing intra-oral putrefaction explains the malodor when waking up. Morning breath odor disappears soon after the intake of food or fluid. The intra-oral placement of a toothpaste containing zinc salts and triclosan has the capacity to reduce the odor for several hours, even in the absence of toothbrushing.

 

Socio-economic aspects

The real concern of the population is the breath malodor which remains during the day and which can cause social and/or relational problems. Subjects who believe they produce malodor can adopt avoidance patterns such as keeping a distance when speaking to others or holding their hand in front of the mouth while speaking. There is also a tendency to constantly use rinses, sprays, chewing gums or pills to mask the breath odor, although many such items have no effect whatsoever or at least no lasting effect.

Even more disturbing is the fact that a number of subjects imagine they have breath malodor when they may not have. This imaginary breath odor, also called halitophobia, has been associated with obsessive-compulsive disorders or hypochondria. It has even led to suicide. For such patients, the presence of a psychologist/psychiatrist at the multidisciplinary malodor consultation is essential.

Tick saliva could hold cancer cure: Brazilian scientists

A South American tick, Amblyomma cajennense , a blood sucking parasite ,may perhaps be the cure for skin cancer . A protein in the saliva of the tick apparently reduces and can even eradicate cancerous cells while leaving healthy cells alone.The protein shares some characteristics with a common anti-coagulant called TFPI (Tissue Factor Pathway Inhibitor), specifically a Kunitz-type inhibitor which also has been shown to interfere with cell growthApparently it did not kill the normal cells.This is hoped to revolutionalize the cancer care.
