Abstract
Aim: Periodontitis is an inflammatory, multifactorial disease which results in destruction of supporting tissue and bone thereby resulting in loosening of the tooth. Tooth loss is one of the major oral issues faced by elderly patients. Thus the present study aimed to investigate the prevalence of tooth loss among periodontitis patients.
 Methodology: Data collection was conducted from June 2020 to March 2021 among 200 periodontitis patients with diabetes mellitus based on the record management system software to analyse the most frequent missing tooth at the time of first visit. Frequency of maxillary anterior, maxillary posterior, mandibular anterior and mandibular posterior tooth loss was assessed in the study.
 Results: Among the frequency distribution the mandibular posterior tooth loss was the most common among periodontitis with diabetes patients. In case of anterior tooth loss the results were almost similar with 16% of maxillary anterior tooth loss and 17% in case of mandibular anterior tooth loss. Male subjects presented with more missing teeth in mandibular posterior tooth region when compared to females but not statistically significant (p>0.05).
 Conclusion: The present study results showed that there is no significant association between sex and maxillary anterior, mandibular anterior, maxillary posterior and mandibular posterior tooth loss (p>0.05). The present study showed that mandibular posterior tooth loss was most frequent among periodontitis with diabetes mellitus patients.

Summary
Diabetes mellitus is a systemic disease characterized by increased blood glucose levels and abnormalities of lipid metabolism due to absence or decreased level of insulin. It affects all the body organs and their functions either directly or indirectly. Tissue destruction in periodontitis results in the breakdown of the collagen fibers of the periodontal ligament, resulting in the periodontal pocket between the gingiva and tooth [3]. The causes of tooth loss vary with geographical location, culture and even time. Studies reported more teeth lost due to periodontal reasons compared with dental caries [4]. Diabetes and periodontitis influence the clinical outcome of each other and control of both influences the clinical improvement of each [5]
