is to find out more information on areas which can be improved to benefit not only the public’s oral health knowledge and status but to improve oral health professional methods of practice as well (Petersen, 2003). The research’s main objective is to inspect tobacco smoking and its effect on periodontitis on the New Zealand adult population. Principal methods to be used include collecting data from participants that would be randomly selected from a sample which could represent the New Zealand adult population and interviewed from a telephone using a survey. The participants would categorize themselves as either as a non-smoker, former smoker or current smoker. The participants would then have their probing pocket depth and gingival recession clinical measured at three different tooth sites with 2.5-3.5mm, 3.5-5mm and over 5mm range recorded. The research hopes to impact the fact that smoking is a risk factor to periodontitis and that smoking should be prevented.

Summary of PROPOSED Research
Background:
Periodontal disease arises from inflammation of the gingivae that is untreated commonly known as gingivitis. The inflammation and infection moves from the gingivae to the bone and supporting ligaments of the teeth. This loss of bone and support will cause the tooth to become mobile and this may lead to it eventually falling out. Being susceptible to periodontal disease is different according to a person as bacterial flora and local and systemic factors (Thomson et al, 2007). It is an important area to research for the New Zealand adult population as tobacco Smoking is known to effect periodontal disease this is done through affecting the level of bone attachment and the soft tissues around the gingivae (Obeid & Bercy, 2000). The appearances clinically of gingivae for a smoker is different as it is fibrotic with rolled margins that are thick, pocketing depth which is larger consistently in maxillary lingual sites, the gingivae being less inflamed compared to the disease level seen and a person having a deeper probing depth, attachment loss and tooth loss than a person at the same age who never has smoked. Smokers have also been known to have impaired healing of gingivae due to blood flow and poorer clinically results to both surgical and non-surgical treatment (Obeid & Bercy, 2000). It is necessary to research this area to find out if the amount of cigarettes smoked has more of an effect on the stage of periodontitis. When researching this topic the necessary confounding factors such as age, sex and socio economic status has to be considered (Bergstrom et al, 2000).
Aim:
The research’s main objective is to inspect tobacco smoking and its effect on periodontitis on the New Zealand adult population.
Description of Study and Design:
A descriptive cross sectional study will be researched to try and find out if tobacco smoking is a casual risk factor for periodontal disease.
Principal methods to be used include collecting data from participants 18 and over that would be randomly selected from a community sample which could represent the New Zealand adult population and interviewed from a telephone using a survey. The participants would categorize themselves as either as a non-smoker, former smoker or current smoker. The current smokers would then have their smoking listed as heavy, moderate or light depending on the amount of cigarettes smoked daily. The participants would then have their probing pocket depth and gingival recession clinical measured at three different tooth sites with 2.5-3.5mm, 3.5-5mm and over 5mm range recorded by a Dentist and Dental Hygienist. The periodontitis will be recorded as no, moderate and severe depending on the bone attachment loss. Age and sex would be used as main confounders. The study will have to be ethically approved by the Otago University Human Ethics Committee. The adults income will be a confounder factor also as it effects their ability to have dental care. The data will be statistically analysed and the results published.
Participants:
The research study requires randomly selected participants male and female over eighteen which will give a sample of adults which could represent the New Zealand adult population. The recruitment process will be through telephone numbers provided from a district health board such as Public health south. The inclusion criteria would be adults over the age of 18 that do not wear full dentures, have enough dentition to be examined at three different random tooth sites and also do not have a medical condition which prevents them from partaking in the clinical
examination.
Main Outcome Measures:
The research’s main goal is to prove through a descriptive cross sectional study that tobacco smoking is a casual risk factor on periodontitis regarding the New Zealand adult population. Another goal is to measure the severity of periodontitis regarding the amount of cigarettes the person smokes weather the risk is increased with more cigarettes smoked or not.
