Abstract
Periodontitis is a chronic inflammatory disease characterised by destruction of supporting structures of teeth. Diabetes mellitus is a systemic disease which is characterised by increased blood glucose level and abnormalities of lipid metabolism, due to absence or decreased level of insulin. The progression of periodontal disease is influenced by factors like microorganism, host response, systemic background and genetic makeup of the host. The aim of the study was to assess the association of the right upper molar involvement between diabetes mellitus and chronic periodontitis. A retrospective data of all the patients reporting for periodontal therapy to Saveetha Dental College And Hospital was collected. The data was extracted from the patients records. Data segregation was done based on 1) age, 2) gender 3) types of periodontitis 4) blood sugar value 5) probing depth and 6) clinical attachment loss. After data collection statistical analysis was done in IBM SPSS software version 20. Chi square test was performed to determine the statistical significance. From the study 67.65% of males and 32.35 % of females with periodontitis had diabetes. The most common age group that was affected was 45-55 years by 44.12%. Patients with diabetes mostly were affected with generalised chronic periodontitis by 82.35%. Probing depth of 3mm was seen mostly in patients with diabetes and periodontitis (35.29%). Clinical attachment loss of 5mm was seen mostly in patients with diabetes and periodontitis (35.29%). Patients with periodontitis had blood sugar level above 200mg/dl by 55.88%. From the chi square test performed to determine the correlation between age of the periodontitis patients and the blood sugar levels, the P value obtained was 0.05 (p<0.05) which shows a positive significance. From the chi square test performed to determine the correlation between diabetic and periodontitis patients with clinical attachment loss showed a positive correlation with p value 0.028 (p <0.05), statistically significant. Within the limits of the present study it can be concluded that the most common age group that was affected was 45-55 years. The most common gender that is affected is male. Patients with diabetes were mostly affected with generalised chronic periodontitis.

Introduction
Chronic periodontitis is a common inflammatory disease of the
supporting tissues of the teeth which is caused by specific microorganisms,
resulting in progressive destruction of the periodontal
ligament and alveolar bone leading to periodontal pocket
formation, gingival recession, or both [1]. Periodontitis is characterised
by inflammatory changes seen in the tooth supporting
tissue which is caused by bacterial infection. Periodontal diseases
include two entities which are gingivitis and periodontitis. Gingivitis
is a reversible inflammation of periodontal tissues whereas
periodontitis also presents destruction of the tooth supporting
structures, and may lead to tooth loss. Gingivitis can be caused
due to bacterial plaque accumulation and is considered as the key
risk factor for the onset of periodontitis. Plaque not just contains
bacteria it also contains viruses which can cause disease progression
[2]. The main etiologic factors of periodontal disease are microorganisms
in combination with individual host susceptibility and environmental factors. The presence of anaerobic gram negative
bacteria causes a local inflammatory response that becomes
chronic and progressive: the inflammation of the gingiva causes
alveolar bone destruction and clinical attachment loss to the teeth,
which is caused by component of microbial plaque that have the
capacity to induce an initial infiltration of inflammatory cells such
as lymphocytes , macrophages and PMNs [3]. Some of the microbial
components such as lipopolysaccharide, activates macrophages
that will synthesise and secrete a great variety and amount of
pro inflammatory molecules such as the cytokines, interleukin -1,
tumor necrosis factor-alpha,prostaglandins and other enzymes
[3]. Tumor necrosis factor-alpha is an important proinflammatory
mediator that causes destruction of periodontal tissues [4].
Similarly recent studies have reported association between Interleukin-
21 levels with periodontitis [5]. ET-1 has also been identified
in periodontal diseases [6, 7]. The attachment loss deepens
the sulcus creating a periodontal pocket that contains millions of
bacterial cells [8, 9]. The most frequently recognised periodontal
pathogens belongs to the three microphillic species (A. actinomycetemcomitans,
Campylobacter rectus and Eikenella corrodens)
and seven anaerobic species (porphyromonas gingivalis, bacteroides
forsythus, treponema denticolla, prevotella intermedia, fusobacterium
nucleatum, eubacterium and spirochetes) [10]. Periodontitis
is highly prevalent and has a negative impact on quality
of life [11]. Periodontitis can be associated with various systemic
conditions [12]. Inorder to prevent the progression of the disease
condition various periodontal therapies can be performed. Periodontal
therapy primarily aims at the elimination of the disease
and maintenance of a functional, healthy dentition and supporting
tissue.Periodontal therapy can be non surgical,surgical and
supportive periodontal therapy. A team has worked on various
regenerative therapies that has been indicated for periodontitis
patients [13-15] and other treatments such as coronally displaced
flap and lip repositioning [16, 17]. Management of generalised
chronic periodontitis patients where the esthetics and function
had to be restored dental implants and implant-supported prosthesis
can be a predictable treatment modality in periodontal
diseases [18]. While performing surgical therapy trauma to the
inferior alveolar nerve is one of the complications during surgical
procedures in the posterior mandible [19]. Various antimicrobial
and chemotherapeutic agents such as chlorhexidine mouth washes
, triclosan are employed for the management of periodontitis
[20]. Herbal medicines and preparations can also be used for the
management of periodontal diseases [21].
Some variations of root anatomy in regards to the shape,size and
number must be considered as predisposing factors for the appearance
and evolution of periodontal disease as it is the favourable
site for the bacterial plaque to accumulate [22, 23]. In multirooted
teeth there are various clinical observations that there is a
high rate of root exposure and consequently the exposure of the
future area is common. In maxillary molars this fact may endanger
the three existent furcation (buccal,mesial and distal) causing
severe periodontal problems. It is likely that once the furcation region
is affected the roots will present a greater loss of periodontal
supporting structure than the other parts of the tooth. Since the
plaque control is very poor and difficult in this region [24].
Diabetes mellitus is a systemic disease with several major complications
affecting both quality and length of life [25]. Diabetes
mellitus is a chronic metabolic disease which is characterised
by hyperglycemia [26]. Hyperglycemia triggers a wide
variety of long term complications in diabetes such as large vessel
disease,cardiomyopathy and kidney and eye impairments [27, 28].
Both type 1 and type 2 diabetes mellitus is associated with elevated
levels of systemic markers of inflammation [29]. The elevated
inflammatory state in diabetes contributes to microvascular and
macrovascular complications [30]. Elevated levels of IL-6 and
TNF alpha have been demonstrated in diabetes [29]. From various
studies it was found that there is a defect in the polymorphonuclear
leukocyte activity in diabetes patients including impares
chemotaxis, phagocytosis and microbial function [31]. Diabetes
mellitus and periodontitis share a common platform based on
pathogenesis. Previously our team has a rich experience in working
on various research projects across multiple disciplines [32-
46]. Hence this study aims to assess the prevalence of upper right
molar involvement between diabetes mellitus and periodontitis.
Materials And Methods
This was a retrospective study in which 86000 patients were reviewed.
The data extraction was from patients records , Saveetha
Dental College And Hospital,Chennai. It was found that a total
of 280 patients had periodontitis. After evaluating periodontal
status and clinical examination of the patients, it was found that
34 patients out of the 280 patients with periodontitis had diabetes
mellitus. The subjects were grouped based on the age into 4
(36-45),(46-55),(56-65),(above 65). From the data obtained it was
found that 28 patients had generalised chronic periodontitis and
6 patients had localised chronic periodontitis. The blood sugar
value of each of the patients were obtained and was grouped into
3; (120-150),(150-200),(Above 200). Periodontal status was diagnosed
based on the probing depth and clinical attachment loss of
16. After the data collection the datas was tabulated in excel sheets
and then transferred to IBM SPSS software version 20. Based on
the blood sugar levels and periodontal parameters that were obtained,
assessment of correlation was performed. Chi square test
was the statistical test that was used to determine the correlation.
Ethical consideration- the original study protocol was reviewed
and approved by the research ethical committee of Saveetha Dental
College And Hospital,Chennai.
Results And Discussion
In the study 67.65% of males and 32.35 % of females with periodontitis
had diabetes. The most common age group that was
affected was 45-55 years by 44.12%. Patients with diabetes mostly
were affected with generalised chronic periodontitis by 82.35%.
Probing depth of 3mm was seen mostly in patients with diabetes
and periodontitis (35.29%). Clinical attachment loss of 5mm
was seen in patients with diabetes and periodontitis (35.29%). Patients
with periodontitis had blood sugar level above 200mg/dl
by 55.88%. From the chi square test performed to determine the
association between age of periodontitis patients and the blood
sugar levels , the P value obtained was 0.05 (p<0.05) which shows
a positive significance. From the chi square test performed to
determine the association between diabetic and periodontitis patients
with clinical attachment loss it shows a positive association
with p value 0.028 (p <0.05), was statistically significant. The association
between clinical attachment loss and blood sugar levels
show a negative significance, p value obtained from chi square test
was 0.570 (p>0.05).
Diabetic patients with periodontitis are presented with subgingival
flora which is composed mainly of capnocytophaga, anaerobic
vibrios, and Actinomyces species [47]. Increased glucose level in
crevicular fluid in diabetic patients may favor the growth of some
of the microbial species. Impairment of neutrophil phagocytosis
is observed in poorly controlled diabetics [48]. Diabetes mellitus
adversely affects the host difference system and acts as a risk factor
for gingivitis and periodontitis. Several altered host responses
are associated with increased incidence and severity of periodontitis
in diabetes patients [49].
In the study the gender that was most commonly affected with
periodontitis and diabetes was males by 67.65%. In a previous
study conducted, prevalence of periodontal disease was almost
equal in both the gender by 59.4% in males and 59.5% in females
[31]. In another study conducted with concurrent finding, it was
reported that males were more commonly affected [50]. Similarly
in a study conducted it was reported that males were most commonly
affected than females with diabetes and periodontitis [51].
In the study the most common age group that was affected with periodontitis and diabetes was 45-55 years. In a previous study it
was found that the most common age group that was affected
with periodontitis and diabetes was above 55years [31]. In yet another
study conducted it was reported that the most common
age group that was affected was 41-64 years by 53.1% [52]. In a
previous study conducted it was found that the most common
age group that was affected was 36-45 years [53]. In the present
study, chi square test performed to determine the correlation between
age of the periodontitis patients and the blood sugar levels,
the P value obtained was 0.05 (p<0.05) which shows a positive
significance. In a study which was conducted Neelima S Rajhans
et al., it was found that there is a prevalence of periodontitis in
diabetic patients by 86% [31]. In another study conducted it was
reported that there is a significance in the prevalence of diabetes
in periodontitis patients with p value=0.000 [50]. In the present
study, the chi square test performed to determine the correlation
between diabetic and periodontitis patients with clinical attachment
loss of upper right molar shows a positive correlation with p value 0.028 (p <0.05), statistically significant. In a previous study
they have reported that there is a significant correlation between
diabetes and molar type in periodontitis with p value <0.05 [54].
In another study it was reported that subjects with type 2 diabetes
have an increased risk of destructive periodontitis with an odds
ratio of 2.81 when clinical attachment loss is used to measure
the disease [55]. Our institution is passionate about high quality
evidence based research and has excelled in various fields [56-66].
The limitation of the study is the limited sample size and it does
not include the ethinic group. It is a single centered study. The
future scope of the study is that a prospective study can be performed
with a larger population.

From the graph we can infer that periodontitis patients with diabetes had a maximum clinical attachment loss of 5mm when the blood sugar level was above 200 mg/dl, however it was statistically not significant (p value 0.570).
Conclusion
Based on present study the most prevalent age group was 45-55
years. The most common gender affected are male. Majority of
diabetes subjects had generalised chronic periodontitis than localised
periodontitis . Although an association between age and
blood sugar levels was established. An association between clinical
attachment loss and blood sugar level was not significant but
further prospective study is required to assess the involvement of
upper right molar with periodontitis, whether age was the causative
factor for chronic periodontitis or blood sugar levels.
