“…The local environment of the tooth appears to be important for the initiation and progression of caries, and local accumulation of plaque is essential for this process to occur (4,5). Plaque accumulation is greatest on the occlusal surfaces of molar teeth from commencement of eruption until establishment of full functional occlusion, and hence this 324 may be the period of greatest risk of caries initiation in the pits and fissures (6,7). Studies have shown that it is possible to arrest completely the development of visible carious lesions through simple mechanical cleaning of teeth (8).…”

Occlusal pit and fissure caries accounts for a high proportion of the total caries burden among children. Studies from Denmark suggested that oral hygiene measures may be effective in the control of occlusal caries in permanent teeth. This study reports on the findings after 24 months of a controlled field trial comparing the caries-preventive effects of a professional tooth-cleaning and dental health education programme (test) with a standard preventive programme (control), comprising selective fissure sealing and application of topical fluorides. School Dental Service clinics of the Health Department of Western Australia, in Perth, were assigned to four test or four control clinics. Schoolchildren, mean age 6 years, with sound newly erupted first permanent molars were included in the study (207 test, 197 control). After 24 months, 179 test and 156 control children were examined by a calibrated examiner who was 'blind' to the test or control status of the child. Thirty-two test and 31 control children developed occlusal caries on the first permanent molars; the estimated risk ratio was 0.90 (95% CI 0.58-1.41). Children in both groups had an average DMFT score of 0.30. The 24-month results suggest that the two preventive programmes did not differ with respect to the control of occlusal caries in newly erupted molars.

“…They are also indispensable from a masticatory point of view. But, according to a report by Miyano et al,27.9% of the upper and 59.8% of the lower irst molars are affected by caries immediately following eruption (Fukada, 1982). It is established that irst molars when compared to the other teeth, takes a long time between the partial and full eruption of its crown.…”

Comparison of incidence of dental caries in the mandibular first molar in teenagers versus adults

The mandibular first molars are one of the first permanent teeth to erupt; thus, it remains the longest in terms of exposure to cariogenic pathogens. Also, its anatomical location and structure make it a prime location for dental caries (DC) but hard to access for cleaning. Thus, we aim to compare its incidence in adults and teenagers because the identification of the most susceptible age for tooth decay is key in prevention and prophylaxis against the same. A retrospective cross-sectional study was conducted by reviewing and analysing the data of 86,000 patient records from June 2019 to April 2020. Patients with treated mandibular first molars were selected from the age group of 13 and above. A Microsoft Excel 2016 data spreadsheet was used to collect data and was later exported to the Statistical Package for the Social Sciences for Windows (Version 20.0, SPSS). The number of males with DC in their mandibular first molar (59%) was higher than that of the females (41%). The highest number of cases were reported to prevail in the 'Young Adults' group, with 56.7%, followed by the 'Middle Adults' with 26%. This shows that adults have a higher incidence of DC in their mandibular first molars than teenagers. Also, there was a clear incidence of 46 having a higher incidence than caries in 36. (52.5% > 47.5%). There is an association between age and incidence of dental DC as proved by our Chi-Square Test, where we obtained a 'p' value of p<0.05, making it statistically significant. Once lost, our teeth cannot be naturally replaced, making prevention imperative. Thus, identifying the age in which we are most prone to decay is a great leap forward. But since the study does present with limitations, further research needs to be done to confirm the same.

“…Estudos têm mostrado uma alta incidência de cárie dentária oclusal presente no decurso do processo de erupção (FUKADA et al, 1982), imediatamente após a erupção (BOYD; CANNON; LEIGHTON, 1952;FUKADA et al, 1982), e um a três anos após a erupção (BOYD; CANNON; LEIGHTON, 1952;SLACK, 1973 …”

“…Uma alta incidência de cárie dentária oclusal está presente durante o processo de erupção (FUKADA et al, 1982), imediatamente após a erupção (BOYD; CANNON; LEIGHTON, 1952;FUKADA et al, 1982), e de 1,0 a 1,5 anos durante a fase de erupção (CARVALHO; THYLSTRUP; EKSTRAND, 1992). Trata-se de um pensamento comum de que a maior susceptibilidade de cárie nas superfícies oclusais, em comparação com superfícies lisas, é resultado das irregularidades estruturais associadas com as fossas e fissuras oclusais (NIKIFORUK, 1984;NEWBRUN, 1982).…”
